To remove the key on vehicles equipped with manual transmissions, turn the key to the Lock position and press the button to remove the ignition key.


STARTING AND OPERATING 229


Key Reminder An alarm will sound to remind you if the key is left in the ignition and the driver’s door is opened.


STARTING PROCEDURES The starter should not be operated for more than 15- second intervals. Waiting a few seconds between such intervals will protect the starter from overheating. Manual Transmission Apply the parking brake, place the gearshift control lever in NEUTRAL and depress the clutch pedal to the floor before starting the vehicle. This vehicle is equipped with a clutch interlocking ignition system. It will not start unless the clutch is fully depressed.


230 STARTING AND OPERATING


Automatic Transmission Start the engine with the selector lever in NEUTRAL or PARK position. Apply the brake before shifting to any driving range. Normal Starting of either a warm or cold engine is obtained without pumping or depressing the accelerator pedal. Turn the key to the START position and release when the engine starts. If the engine fails to start within 10 seconds, turn the key to the OFF position, wait 5
seconds, then repeat the starting procedure. NOTE: This vehicle is equipped with a transmission shift interlocking system. The brake pedal must be depressed to shift out of Park (P).


If Engine Fails To Start If the engine fails to start after you have followed the normal starting procedure, it may be flooded. Push the accelerator pedal all the way to the floor and hold it there while cranking the engine. This should clear any excess fuel in case the engine is flooded.


CAUTION!


To prevent damage to the starter, do not crank the engine for more than 15–seconds at a time. Wait 10 to 15 seconds before trying again.


If the engine has been flooded, it may start to run, but not have enough power to continue running when the key is released. If this occurs, continue cranking with the accel- erator pedal pushed all the way to the floor. Release the accelerator pedal and the key once the engine is running smoothly. If the engine shows no sign of starting after two 15
second periods of cranking with the accelerator pedal held to the floor, the normal starting procedure should be repeated.


WARNING!


Never pour fuel or other flammable liquids into the throttle body air inlet opening in an attempt to start the vehicle. This could result in a flash fire causing serious personal injury.


STARTING AND OPERATING 231


Engine Block Heater— If Equipped The engine block heater warms the engine coolant and permits quicker starts in cold weather. Connect the cord to a standard 110-115 volt AC electrical outlet with grounded, three-wire extension cord. The engine block heater cord is routed under the hood to the right side of the vehicle and held to the body with removable clips.


WARNING!


Remember to disconnect the cord before driving. Damage to the 110-115 volt electrical cord could cause electrocution.


232 STARTING AND OPERATING


After Starting The idle speed is automatically controlled and will de- crease as the engine warms up.


CAUTION!


Long periods of engine idling, especially at high engine speeds can cause excessive exhaust tempera- tures which can damage your vehicle. Do not leave your vehicle unattended with the engine running.


WARNING!


Do not leave children or animals inside parked vehicles in hot weather. Interior heat build up may cause serious injury or death.


TRANSMISSION SHIFTING


Automatic Transmission with Overdrive The gear shift selector display, located in the instrument panel cluster, indicates the transmission gear range (the selector is illuminated for night driving). The selector lever is mounted on the right side of the steering column. You must depress the brake pedal, to pull the selector lever out of park (P) position (Brake Interlock System). To drive, move the selector lever from Park or Neutral to the desired drive position. Pull the selector lever toward you when shifting into Reverse, Second, First or Park, or when shifting out of Park. Gear Ranges DO NOT race the engine when shifting from Park or Neutral position into another gear range.


STARTING AND OPERATING 233


WARNING!


Your vehicle could move and injure you and others if it is not completely in P (Park). Check by trying to move the gearshift lever back and forth without first pulling it toward you after you have set it in P. Make sure it is in Park before leaving the vehicle.


“P” Park This gear position supplements the parking brake by locking the transmission. The engine can be started in this range. Never use Park while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. Always apply parking brake first, then place the selector in Park position. On 4-wheel-drive vehicles be sure that the transfer case is in a drive position!


WARNING!


Never use Park position on an automatic transmis- sion as a substitute for the parking brake. Always apply parking brake fully when parked to guard against vehicle movement and possible injury or damage.


234 STARTING AND OPERATING


WARNING!


It is dangerous to shift the selector lever out of “P” or “N” if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in re- verse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal.


“R” Reverse Use this range only after the vehicle has come to a complete stop.


“N” Neutral Shift to Neutral when the vehicle is standing for pro- longed periods with the engine running. The engine may be started in this range. Set the parking brake if you must leave the vehicle. NOTE: Towing the vehicle, coasting, or driving, with the transmission in neutral (N) position, can cause severe damage to the transmission. “D” Drive This position provides all forward gears, including 3rd gear direct and 4th or 5th (if equipped) gear overdrive (see Overdrive Operation). Use this range for most city and highway driving.


“2” Second Use this position for driving slowly in heavy city traffic or on mountain roads where more precise speed control is desirable. Use it also when climbing long grades, and for engine braking when descending moderately steep grades. NOTE: Do not exceed maximum engine speed. “1” First Use this position for driving up very steep hills and for engine braking at low speeds (20 mph [32 km/h] or less) when going downhill. NOTE: Do not exceed maximum engine speed.


STARTING AND OPERATING 235


Overdrive Operation The overdrive automatic transmission contains an elec- tronically controlled fourth and fifth (if equipped) speed (Overdrive). The transmission will automatically shift from Drive to Overdrive if the following conditions are present: • the transmission selector is in Drive; • the engine coolant has reached normal operating tem- • vehicle speed is above approximately 30 mph (48
• the “TOW/HAUL” switch has not been activated; • transmission has reached normal operating tempera-


perature;


km/h);


ture.


236 STARTING AND OPERATING


If the vehicle is started in extremely cold tem- NOTE: peratures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for operation at this temperature. Normal operation will resume when the transmission fluid temperature has risen to a suitable level. Refer also to the Note under torque converter clutch, later in this section. If the transmission temperature gets extremely hot, the transmission will automatically select the most desirable gear for operation at this temperature. If the transmission temperature becomes hot enough the TRANS TEMP light may illuminate and the transmission may downshift out of Overdrive until the transmission cools down. After cooldown, the transmission will resume normal opera- tion. The transmission will downshift from Overdrive to Drive if the accelerator pedal is fully depressed at vehicle speeds above approximately 35 mph (56 km/h).


When To Use “TOW/HAUL” Mode


When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting oc- curs, press the “TOW/HAUL” button. This will improve performance and reduce the potential for transmission overheating or failure due to excessive shifting. When operating in “TOW/HAUL” mode, (if


5th gear


equipped) is disabled and 2-3 and 3-4 shift patterns are modified. Shifts into Overdrive (4th gear) are allowed during steady cruise (for improved fuel economy) and automatic closed-throttle downshifts to 3rd gear (for improved braking) will occur during steady braking. The “TOW/HAUL” light will illuminate in the instru- ment cluster to indicate when the switch has been activated. Pressing the switch a second time restores normal operation. If the “TOW/HAUL” mode is desired, the button must be pressed each time the engine is started. Torque Converter Clutch A feature, designed to improve fuel economy, has been included in the automatic transmission on your vehicle. A clutch within the torque converter engages automati- cally at calibrated speeds. This may result in a slightly different feeling or response during normal operation in


STARTING AND OPERATING 237


high gear. When the vehicle speed drops or during acceleration when the transmission downshifts to second gear, the clutch automatically disengages. NOTE: The torque converter clutch will not engage until the transmission fluid and engine coolant are warm [usually after 1-3 miles (1.6 - 4.8 km) of driving]. Because the engine speed is higher when the torque converter clutch is not engaged, it may seem as if the transmission is not shifting into Overdrive when cold. This is normal. Pressing the “TOW/HAUL” button, when the transmis- sion is sufficiently warm, will demonstrate that the transmission is able to shift into and out of overdrive. If the vehicle has not been driven in several NOTE: days, the first few seconds of operation after shifting the transmission into gear may seem sluggish. This is due to the fluid partially draining from the torque converter into the transmission. This condition is normal and will not


238 STARTING AND OPERATING


cause damage to the transmission. The torque converter will refill within five seconds of shifting from Park into any other gear position. Manual Transmission


NOTE: The parking brake should be engaged before leaving the vehicle, especially on an incline. Truck models with manual transmission are equipped with a clutch interlocking ignition system. The clutch pedal must be fully depressed to start the vehicle. Fully depress the clutch pedal before shifting gears. As you release the clutch pedal, lightly depress the accelera- tor pedal. To shift into Reverse, come to a complete stop. Depress the clutch and pause briefly to allow the gear train to stop. Move the shift lever from the Neutral position straight across and back into Reverse.


Never drive with your foot resting on the clutch pedal, or attempt to hold the vehicle on a hill with the clutch pedal partially engaged, as this will cause abnormal wear on the clutch. Recommended Vehicle Shift Speeds To utilize your manual transmission efficiently for both fuel economy and performance, it should be upshifted as listed in recommended shift speed chart. Shift at the vehicle speeds listed for acceleration. Earlier upshifts during cruise conditions (steady speeds) will result in increased fuel economy, and may be used as indicated. Manual Transmission – 5–Speed (NV4500) 2500 and 3500 models are equipped with the NV4500
manual transmission. This transmission has a “creeper” 1st gear which should be used to start from a standing position when carrying a payload or towing a trailer. Damage to the clutch can result from starting in 2nd or


3rd gear with a loaded vehicle. An unloaded vehicle may be launched in 2nd gear. Use each gear in numerical order – do not skip a gear. For most city driving you may find it easier to use only 1st through 4th gear ranges. For steady highway driving with light accelerations, 5th gear is recommended. To shift into 5th gear, move the shift lever to the right beyond the spring pressure point and push it forward. When shifting from 5th to 4th gear, pull the lever down toward you in one motion. Do not pull the lever sharply left as you may shift accidentally into 2nd gear and damage the transmission.

Manual Transmission — 6-Speed NOTE: The parking brake should be engaged before leaving the vehicle, especially on an incline. This model is equipped with a clutch interlocking igni- tion system. The clutch pedal must be fully depressed to start the vehicle.


240 STARTING AND OPERATING


Fully depress the clutch pedal before shifting gears. As you release the clutch pedal, lightly depress the accelera- tor pedal. When launching a stationary vehicle, keep the engine speed low until the clutch is fully engaged. Damage to the clutch can result from starting in 2nd or 3rd gear with a loaded vehicle. Use each gear in numeri- cal order – do not skip a gear. For improved clutch life, all six forward gears should be used. For steady highway driving with light acceleration, 6th gear is recommended. When shifting from 4th to 5th gear, apply side effort away and forward without push- ing hard enough to engage Reverse gear. Shifting from 5th to 6th requires the same side effort or the lever will return to center resulting in a shift into 4th gear and damage the transmission, clutch, or engine. You should use low gear when starting from a standing position if under a heavy load.


To shift into Reverse, come to a complete stop. Depress the clutch and pause briefly to allow the gear train to stop. Move the shift lever from the Neutral position straight across and up into Reverse. Never drive with your foot resting on the clutch pedal, or attempt to hold the vehicle on a hill with the clutch pedal partially engaged, as this will cause abnormal wear on the clutch. Recommended Shift Speeds To use your manual transmission for fuel economy it should be upshifted as listed below. Shift at the vehicle speeds listed for acceleration. Earlier upshifts during cruise conditions (relatively steady speeds) will result in increased fuel economy, and may be used as indicated. Higher upshift speeds may be used to obtain a desired acceleration rate.

Downshifting Moving from a high gear down to a lower gear is recommended to preserve brakes when driving down steep hills. In addition, downshifting at the right time provides better acceleration when you desire to resume speed. For acceleration at speeds less than 20 mph (30
km/h), 2nd gear is recommended.


STARTING AND OPERATING 241


CAUTION!


When descending a hill, be very careful to downshift one gear at a time to prevent overspeeding the engine which can cause valve damage.


FOUR-WHEEL- DRIVE OPERATION — IF EQUIPPED • Four-Wheel-Drive Dodge Ram Trucks are equipped with either a Manually Shifted transfer case or an Electronically Shifted transfer case. See the operating instructions for your transfer case, located within this section.


242 STARTING AND OPERATING


Manually Shifted Transfer Case Operating Information/Precautions The transfer case provides 4 mode positions - 2 (rear)- wheel-drive high range, 4-wheel-drive high range, neu- tral, and 4-wheel-drive low range. This transfer case is intended to be driven in the 2-wheel- drive position (2H) for normal street and highway con- ditions such as dry hard surfaced roads. When additional traction is required the transfer case 4H and 4L positions can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. This is accomplished by simply moving the shift lever to the desired positions. The 4H and 4L positions are intended for loose, slippery road surfaces only. Driving in the 4H and 4L positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components.


The 4-wheel-drive light (4WD), located in the instrument cluster, alerts the driver that the vehicle is in 4-wheel drive and that the front and rear driveshafts are locked together. This light illuminates when the transfer case is shifted to either the 4H or 4L positions. There is no light for the 2H or N (Neutral) positions. When operating your vehicle in 4L, the engine speed is approximately three times that of the 2H or 4H positions at a given road speed. Take care not to overspeed the engine and do not exceed 25 mph (40 km/h). Proper operation of 4-wheel-drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference will adversely affect shifting and can cause damage to the transfer case.


NOTE: Do not attempt to make a shift while only the front or rear wheels are spinning. The transfer case is not equipped with a synchronizer and therefore the front and rear driveshaft speeds must be equal for the shift to take place. Shifting while only the front or rear wheels are spinning can cause damage to the transfer case. Because 4-wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit. NOTE: Delayed shifts out of four-wheel drive may be experienced due to uneven tire wear, low or uneven tire pressures, excessive vehicle loading, or cold tempera- tures.


STARTING AND OPERATING 243


WARNING!


You or others could be injured if you leave the vehicle unattended with the transfer case in the Neutral (N) position without first fully engaging the parking brake. The transfer case Neutral (N) position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move regardless of the transmission position. The parking brake should always be applied when the driver is not in the vehicle.


For additional information on the appropriate use of each transfer case mode position see the information below: 2H Rear Wheel Drive High Range - Normal street and highway driving. Dry hard surfaced roads.


244 STARTING AND OPERATING


4H 4-Wheel-Drive High Range - Locks the front and rear driveshafts together. Forces the front and rear wheels to rotate at the same speed. Additional traction for loose, slippery road surfaces only. Neutral - Disengages both the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle. See Recreational Towing for more infor- mation. 4L 4-Wheel-Drive Low Range - Low speed 4-wheel-drive. Locks the front and rear driveshafts together. Forces the front and rear wheels to rotate at the same speed. Additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h).


Shifting Procedure - Manually Shifted Transfer Case


2H ⇔ 4H Shifting between 2H and 4H can be made with the vehicle stopped or in motion. If the vehicle is in motion, shifts can be made up to 55 mph (88 km/h). With the


vehicle in motion, the transfer case will engage / disen- gage faster if you momentarily release the accelerator pedal after completing the shift. Apply a constant force when shifting the transfer case lever. 2H or 4H ⇔ 4L With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift an automatic transmission to N (Neutral) or depress the clutch on a manual transmission. While the vehicle is coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer case lever firmly to the desired position. Do not pause in transfer case N (Neutral). NOTE: Pausing in transfer case N (Neutral) in vehicles equipped with an automatic transmission may require shutting the engine OFF to avoid gear clash while completing the shift. If difficulty occurs, shift automatic transmission to N (Neutral), hold foot on brake, and turn engine OFF. Make shift to the desired mode.


STARTING AND OPERATING 245


NOTE: Shifting into or out of 4L is possible with the vehicle completely stopped, however difficulty may oc- cur due to the mating clutch teeth not being properly aligned. Several attempts may be required for clutch teeth alignment and shift completion to occur. The pre- ferred method is with the vehicle rolling 2 to 3 mph (3 to 5 km/h). Avoid attempting to engage or disengage 4L with the vehicle moving faster than 2 to 3 mph (3 to 5
km/h). NOTE: Do not attempt to shift to or from 4L while the transmission is in gear or clutch is engaged. Transfer Case Reminder Light The four-wheel-drive operating light (4WD), located in the instrument cluster, is used to alert the driver that the front axle is fully engaged and all four wheels are driving.


246 STARTING AND OPERATING


Electronically Shifted Transfer Case Operating Information/Precautions This is an electric shift transfer case and is operated by the 4WD Control Switch (Transfer Case Switch), which is located on the instrument panel. The Electronically Shifted transfer case provides 4 mode positions: 2 (rear) wheel drive high range or all wheel drive high range, 4 wheel drive high range, 4 wheel drive low range, and neutral. The Electronically Shifted transfer case is designed to be driven in the 2 wheel drive position (2WD) or all wheel drive position (AWD) for normal street and highway conditions (dry hard surfaced roads). When additional traction is required, the transfer case 4HI and 4LO positions can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. This is accomplished by rotating the 4WD Control Switch to the desired


position - see Shifting Procedure section for specific shifting instructions. The 4HI and 4LO positions are designed for loose, slippery road surfaces only. Driving in the 4HI and 4LO positions on dry hard surfaced roads may cause increased tire wear and damage to the driv- eline components. NOTE: The transfer case Neutral (N) position is selected by depressing the recessed button located on the lower left hand corner of the 4WD Control Switch. The transfer case Neutral (N) position is to be used for recreational towing only. See the Recreational Towing section for specific procedures on shifting into and out of Neutral (N). Transfer Case Position Indicator Lights — Electronically Shifted Transfer Case Only Transfer case position indicator lights are located on the Four-Wheel-Drive Control Switch, found on your instru- ment panel, and indicate the current and desired transfer


case selection. When you select a different transfer case position, the indicator lights will do the following: If All Shift Conditions are Met 1. The current position indicator light will turn OFF. 2. The selected position indicator light will flash until the transfer case completes the shift. 3. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON. If One or More Shift Conditions are not Met 1. The indicator light for the current position will remain ON. 2. The newly selected position indicator light will con- tinue to flash. 3. The transfer case will not shift.


STARTING AND OPERATING 247


NOTE: Before retrying a selection, make certain that all the necessary requirements for selecting a new transfer case position have been met. To retry the selection, turn the control knob back to the current position, wait five (5) seconds, and retry selection. To find the shift require- ments, refer to the ⬙Shifting Procedure⬙ for your transfer case, located in this section of the owner’s manual. The “SERVICE 4WD” warning light monitors the electric shift 4WD system. If this light remains on after engine start up or illuminates during driving, it means that the 4WD system is not functioning properly and that service is required.


248 STARTING AND OPERATING


WARNING!


Always engage the parking brake when powering down the vehicle if the ⴖService 4WDⴖ light is illuminated. Not engaging the parking brake may allow the vehicle to roll which may cause personal injury.


NOTE: Do not attempt to make a shift while only the front or rear wheels are spinning. The transfer case is not equipped with a synchronizer and therefore the front and rear driveshaft speeds must be equal for the shift to take place. Shifting while only the front or rear wheels are spinning can cause damage to the transfer case.


When operating your vehicle in 4LO, the engine speed is approximately three times that of the 2WD/AWD or 4HI positions at a given road speed. Take care not to over- speed the engine and do not exceed 25 mph (40 km/h). Proper operation of 4 wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Because 4 wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit.


WARNING!


You or others could be injured if you leave the vehicle unattended with the transfer case in the Neutral (N) position without first fully engaging the parking brake. The transfer case Neutral (N) position disengages both the front and rear driveshafts from the powertrain and will allow the vehicle to move regardless of the transmission position. The parking brake should always be applied when the driver is not in the vehicle.


For additional information on the appropriate use of each transfer case mode position see the information below: 2WD/AWD Rear Wheel Drive High Range - Normal street and highway driving. Dry hard surfaced roads.


STARTING AND OPERATING 249


4HI 4 Wheel Drive High Range - Locks the front and rear driveshafts together. Forces the front and rear wheels to rotate at the same speed. Additional traction for loose, slippery road surfaces only. 4LO 4 Wheel Drive Low Range - Low speed 4 wheel drive. Locks the front and rear driveshafts together. Forces the front and rear wheels to rotate at the same speed. Additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h). Neutral - Disengages both the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle. See Recreational Towing for more infor- mation.


250 STARTING AND OPERATING


Shifting Procedure - Electronically Shifted Transfer Case


If any of the requirements to select a new NOTE: transfer case position have not been met, the transfer case will not shift.The indicator light for the previous position will remain ON and the newly selected position indicator light will continue to flash until all the requirements for the selected position have been met. To retry a shift:


return the control knob back to the original position, make certain all shift requirements have been met, wait five (5) seconds and try the shift again. If all the requirements to select a new transfer NOTE: case position have been met, the current position indica- tor light will turn OFF, the selected position indicator light will flash until the transfer case completes the shift. When the shift is complete, the indicator light for the selected position will stop flashing and remain ON. 2WD/AWD ⇔ 4HI Rotate the 4WD Control Switch to the desired position. Shifts between 2WD/AWD and 4HI can be done with the vehicle stopped or in motion. With the vehicle in motion,


STARTING AND OPERATING 251


the transfer case will engage / disengage faster if you momentarily release the accelerator pedal after turning the control switch. If the vehicle is stopped, the ignition key must be in the ON position with the engine either RUNNING or OFF. This shift cannot be completed if the key is in the accessory position. NOTE: The 4x4 system will not allow shifts between (2WD/AWD)/4HI if the front and/or rear wheels are spinning (no traction). In this situation the selected position indicator light will flash and the original posi- tion indicator light will remain ON. At this time, reduce speed and stop spinning the wheels to complete the shift.


252 STARTING AND OPERATING


2WD/AWD or 4HI ⇔ 4LO NOTE: When shifting into or out of 4LO some gear noise may be heard. This noise is normal and is not detrimental to the vehicle or occupants. Shifting can be performed with the vehicle rolling 2 to 3
mph (3 to 5 km/h) or completely stopped. USE EITHER OF THE FOLLOWING PROCEDURES: Preferred Procedure 1. With engine RUNNING, slow vehicle to 2 to 3 mph (3
to 5 km/h). 2. Shift the transmission into NEUTRAL (depress clutch on manual transmissions). 3. While still rolling, rotate the transfer case control switch to the desired position. 4. After the desired position indicator light is ON (not flashing), shift transmission back into gear (release clutch on manual transmissions).


Alternate Procedure 1. Bring the vehicle to complete stop. 2. With the key ON and the engine either OFF or RUNNING, shift the transmission into NEUTRAL (de- press clutch on manual transmissions). 3. Rotate the transfer case control switch to the desired position. 4. After the desired position indicator light is ON (not flashing), shift transmission back into gear (release clutch on manual transmissions). If steps 1 or 2 of either the Preferred or Alternate NOTE: Procedure are not satisfied prior to attempting the shift or if they no longer are being met while the shift attempt is in process then the desired position indicator light will flash continuously while the original position indicator light is ON, until all requirements have been met.


NOTE: The ignition key must be ON for a shift to take place and for the position indicator lights to be operable. If the key is not ON then the shift will not take place and no position indicator lights will be on or flashing. NOTE: than 21 days, refer to the section on “Vehicle Storage.”


If your are leaving your vehicle stored for longer


LIMITED-SLIP DIFFERENTIAL — IF EQUIPPED The limited-slip differential provides additional traction on snow, ice, mud, sand and gravel, particularly when there is a difference between the traction characteristics of the surface under the right and left rear wheels. During normal driving and cornering, the limited-slip unit per- forms similarly to a conventional differential. On slip- pery surfaces, however, the differential delivers more of the driving effort to the rear wheel having the better traction.


STARTING AND OPERATING 253


The limited-slip differential is especially helpful during slippery driving conditions. With both rear wheels on a slippery surface, a slight application of the accelerator will supply maximum traction. When starting with only one rear wheel on an excessively slippery surface, slight momentary application of the parking brake may be necessary to gain maximum traction.


WARNING!


On vehicles equipped with a limited-slip differen- tial, never run the engine with one rear wheel off the ground, since the vehicle may drive through the rear wheel remaining on the ground. You could lose control of the vehicle.


254 STARTING AND OPERATING


Care should be taken to avoid sudden accelerations when both rear wheels are on a slippery surface. This could cause both rear wheels to spin, and allow the vehicle to slide sideways on the crowned surface of a road or in a turn.


PARKING BRAKE The foot operated parking brake is positioned below the lower left corner of the instrument panel. To release the parking brake, pull the parking brake release handle. NOTE: The instrument cluster red brake warning light will come on and flash to indicate that the parking brake is applied. You must be sure that the parking brake is fully applied before leaving the vehicle.


Be sure the parking brake is firmly set when parked and the gear shift lever is in the PARK position. When parking on a hill you should apply the parking brake before placing the gear shift lever in PARK, otherwise the load on the transmission locking mechanism may make it difficult to move the selector out of PARK.


WARNING!


• Always fully apply the parking brake when leav- ing your vehicle, or it may roll and cause damage or injury. Also be certain to leave an automatic transmission in Park, a manual transmission in Reverse or first gear. Failure to do so may allow the vehicle to roll and cause damage or injury. • Leaving children in a vehicle unattended is dan- gerous for a number of reasons. A child or others could be injured. Children should be warned not to touch the parking brake or the gear selector lever. Don’t leave the keys in the ignition. A child could operate power windows, other controls, or move the vehicle. • Be sure the parking brake is fully disengaged before driving, failure to do so can lead to brake problems due to excessive heating of the rear brakes.


STARTING AND OPERATING 255


When parking on a hill, turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade. The parking brake should always be applied whenever the driver is not in the vehicle.


BRAKE SYSTEM If power assist is lost for any reason (for example, repeated brake applications with the engine off), the brakes will still function. However, you will experience a substantial increase in braking effort to stop the vehicle. If either the front or rear hydraulic systems lose normal capability, the remaining system will still function with some loss of overall braking effectiveness. This will be evident by increased pedal travel during application, greater pedal force required to slow or stop, and activa- tion of the BRAKE warning lamp and the ABS lamp (if equipped) during brake use.


256 STARTING AND OPERATING


3500 Dual Rear Wheel Models Only The brake system power assist is provided by a hydro- boost unit which shares fluid with the power steering system. You may experience some clicking or hissing noises from the hydro-boost system during hard braking conditions. NOTE: Under cold temperatures, pedal effort will be higher than normal until the power steering oil reaches operating temperature. Brake Noise During normal operation of the brake system certain noises may be present from time to time. Occasional ⬙groan⬙ or ⬙squeal⬙ noises may occur during normal operation of the brake system which may not be indica- tive of a problem. These noises may be heard at any time the brakes are applied but may be more noticeable during the first few brake applications in the morning. Moisture, hot or cold temperature, dust, and or other debris may


also contribute to the noise condition. Repeated or con- tinuous noises during braking may be an indication that the brake linings are worn and in need of replacement. Rear Wheel Anti-Lock Brake System — RWAL The Anti-lock Brake System provides increased vehicle stability and brake performance under most braking conditions. The system automatically controls the opera- tion of the rear brakes to prevent rear wheel lockup. The system remains operational in the four-wheel drive mode. The level of performance is reduced when the front brakes are locked up. This may cause the rear brakes to lockup through the drivetrain, which may reduce the effectiveness of the Anti-lock Brake System. During severe braking conditions, particularly with changing road surfaces, such as ice to concrete, a slight drop or minor pulsation may be felt in the brake pedal.


WARNING!


Both Anti-Lock Brake Systems contain sophisticated electronic equipment. It may be susceptible to inter- ference caused by improperly installed or high out- put radio transmitting equipment. This interference can cause possible loss of anti-lock braking capabil- ity. Installation of such equipment should be per- formed by qualified professionals.


Four-Wheel Anti-Lock Brake System — If Equipped This Anti-lock Brake System is designed to aid the driver in maintaining vehicle control under adverse braking conditions. The system operates with a separate com- puter to modulate hydraulic pressure to prevent wheel lockup and help avoid skidding on slippery surfaces.


STARTING AND OPERATING 257


The system’s pump motor runs during an ABS stop to provide regulated hydraulic pressure. The pump motor makes a low humming noise during operation. This is normal. When you are in a severe braking condition involving use of the Anti-lock Brake System, you will experience some pedal drop as the vehicle comes to a complete stop. This is the result of the system reverting to the base brake system and is normal. Engagement of the Anti-lock Brake System may be accompanied by a pulsing sensation. You may also hear a clicking noise. These occurrences are normal, and indi- cate that the system is functioning.


258 STARTING AND OPERATING


ABS Warning Light The Anti-lock Brake System includes an amber warning light. When the light is illuminated, the Anti-lock Brake System is not functioning. The system reverts to standard non-anti-lock brakes.


WARNING!


Pumping of the anti-lock brakes will diminish their effectiveness and may lead to an accident. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop.


WARNING!


• Anti-lock system (ABS) cannot prevent the natu- ral laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency be- yond that afforded by the condition of the vehicle brakes and tires or the traction afforded.


• The ABS cannot prevent accidents,


including those resulting from excessive speed in turns, following another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents. • The capabilities of an ABS equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.


POWER STEERING Your power steering system will provide mechanical steering capability if power assist is lost. If for any reason the hydraulic pressure is interrupted, it will still be possible to steer your vehicle. Under these conditions you will experience a substantial increase in steering effort.

Tire and Loading Information Placard


Tire and Loading Information


This placard tells you important information about the: 1) number of people that can be carried in the vehicle 2) the total weight your vehicle can carry 3) the tire size designed for your vehicle 4) the cold tire inflation pressures for the front, rear and spare tires.


STARTING AND OPERATING 265


Loading The vehicle maximum load on the tire must not exceed the load carrying capacity of the tire on your vehicle. You will not exceed the tire’s load carrying capacity if you adhere to the loading conditions, tire size and cold tire inflation pressures specified on the Tire and Loading Information placard and the Vehicle Loading section of this manual. NOTE: Under a maximum loaded vehicle condition, gross axle weight ratings (GAWR’s) for the front and rear axles must not be exceeded. For further information on GAWR’s, vehicle loading and trailer towing, see the Vehicle Loading section of this manual. To determine the maximum loading conditions of your vehicle, locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on the Tire and Loading Information placard. The


266 STARTING AND OPERATING


combined weight of occupants, cargo/luggage and trailer tongue weight (if applicable) should never exceed the weight referenced here. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occu- pants and cargo should never exceed XXX pounds” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and pas- sengers from XXX kilograms or XXX pounds. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1400 lbs. and there will be five 150 lb. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lb. (since 5 x 150 = 750, and 1400 – 750 = 650 lb.)


5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4. 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. NOTE: The following table shows examples on how to calculate total load, cargo/luggage and towing capacities of your vehicle with varying seating configurations and number and size of occupants. This table is for illustra- tion purposes only and may not be accurate for the seating and load carry capacity of your vehicle. NOTE: For the following example the combined weight of occupants and cargo should never exceed 865 lbs. (392
Kg).


STARTING AND OPERATING 267


268 STARTING AND OPERATING


WARNING!


1. Safety—


Overloading of your tires is dangerous. Overloading can cause tire failure, affect vehicle handling, and increase your stopping distance. Use tires of the recommended load capacity for your vehicle. Never overload them.


TIRES—GENERAL INFORMATION


Tire Pressure Proper tire inflation pressure is essential to the safe and satisfactory operation of your vehicle. Three primary areas are affected by improper tire pressure:


WARNING!


Improperly inflated tires are dangerous and can cause accidents. • Under inflation increases tire flexing and can result in tire failure. • Over inflation reduces a tire’s ability to cushion shock. Objects on the road and chuck holes can cause damage that results in tire failure. • Unequal tire pressures can cause steering problems. You could lose control of your vehicle. • Over inflated or under inflated tires can affect vehicle handling and can fail suddenly, resulting in loss of vehicle control. • Unequal tire pressures from one side of the vehicle to the other can cause the vehicle to drift to the right or left. Always drive with each tire inflated to the recom- mended cold tire inflation pressure.


2. Economy— Improper inflation pressures can cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Underinflation also increases tire rolling resistance and results in higher fuel consumption. 3. Ride Comfort and Vehicle Stability— Proper tire inflation contributes to a comfortable ride. Overinflation produces a jarring and uncomfortable ride. Tire Inflation Pressures The proper cold tire inflation pressure for passenger cars is listed on either the face of the driver’s door or the driver’s side “B” pillar. For vehicles other than passenger cars, the cold tire inflation pressures are listed on either the “B” pillar, the Certification Label or in the Tire Inflation Pressures brochure in the glove compartment. Some vehicles may have Supplemental Tire Pressure Information for vehicle loads that are less than the


STARTING AND OPERATING 269


maximum loaded vehicle condition. These pressure con- ditions will be found in the “Supplemental Tire Pressure Information” section of this manual.


Tire Placard Location


The pressure should be checked and adjusted as well as inspecting for signs of tire wear or visible damage at least once a month. Use a good quality pocket-type gauge to


270 STARTING AND OPERATING


check tire pressure. Do not make a visual judgement when determining proper inflation. Radial tires may look properly inflated even when they are under inflated.


CAUTION!


After inspecting or adjusting the tire pressure al- ways reinstall the valve stem cap–if equipped. This will prevent moisture and dirt from entering the valve stem, which could damage the valve stem.


Inflation pressures specified on the placard are always “cold tire inflation pressure”. Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least 3 hours, or driven less than 1mile (1 km) after a 3 hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire side wall.


Check tire pressures more often if subject to a wide range of outdoor temperatures, as tire pressures vary with temperature changes. Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C) of air temperature change. Keep this in mind when checking tire pressure inside a garage especially in the winter. Example: If garage temperature = 68° F (20° C) and the outside temperature = 32° F (0° C) then the cold tire inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi (7 kPa) for every 12° F (7° C) for this outside temperature condition. Tire pressure may increase from 2 to 6 psi (13 to 40 kPa) during operation. DO NOT reduce this normal pressure build up or your tire pressure will be too low.


Tire Pressures for High Speed Operation The manufacturer advocates driving at safe speeds within posted speed limits. Where speed limits or condi- tions are such that the vehicle can be driven at high speeds, maintaining correct tire inflation pressure is very important. Increased tire pressure and reduced vehicle loading may be required for high speed vehicle opera- tion. Refer to original equipment or an authorized tire dealer for recommended safe operating speeds, loading and cold tire inflation pressures.


STARTING AND OPERATING 271


WARNING!


High speed driving with your vehicle under maxi- mum load is dangerous. The added strain on your tires could cause them to fail. You could have a serious accident. Don’t drive a vehicle loaded to the maximum capacity at continuous speeds above 75
mph (120 km/h).


272 STARTING AND OPERATING


Radial-Ply Tires


WARNING!


Combining radial ply tires with other types of tires on your vehicle will cause your vehicle to handle poorly. The instability could cause an accident. Al- ways use radial ply tires in sets of four (or 6, in case of trucks with dual rear wheels). Never combine them with other types of tires.


Cuts and punctures in radial tires are repairable only in the tread area because of sidewall flexing. Consult your authorized tire dealer for radial tire repairs.


Compact Spare Tire — If Equipped The compact spare is for temporary emergency use with radial tires. It is engineered to be used on your style vehicle only. Since this tire has limited tread life, the original tire should be repaired (or replaced) and rein- stalled at the first opportunity.


WARNING!


Temporary use spare tires are for emergency use only. With these tires, do not drive more than 50 mph (80 km/h). Temporary-use spare tires have limited tread life. When two or more tread wear indicators appear in adjacent grooves, the temporary use spare tire needs to be replaced. Be sure to follow the warnings which apply to your spare. Failure to do so could result in spare tire failure and loss of vehicle control.


Do not install a wheel cover or attempt to mount a conventional tire on the compact spare wheel, since the wheel is designed specifically for the compact spare. Do not install more than one compact spare tire/wheel on the vehicle at any given time.


CAUTION!


Because of the reduced ground clearance, do not take your vehicle through an automatic car wash with the compact spare installed. Damage to the vehicle may result.


STARTING AND OPERATING 273


Limited Use Spare — If Equipped The limited use spare tire is for temporary emergency use on your vehicle. This tire is identified by a limited use spare tire warning label located on the limited use spare tire and wheel assembly. This tire may look like the original equipped tire on the front or rear axle of your vehicle, but it is not. Installation of this limited use spare tire affects vehicle handling. Since it is not the same tire, replace (or repair) the original tire and reinstall on vehicle at the first opportunity.


274 STARTING AND OPERATING


WARNING!


The limited use spare tires are for emergency use only. Installation of this limited use spare tire affects vehicle handling. With this tire, do not drive more than 60 mph (100 km/h). Keep inflated to the cold tire inflation pressure listed on either your tire placard or limited use spare tire and wheel assembly. Replace (or repair) the original tire at the first opportunity and reinstall it on your vehicle. Failure to do so could result in loss of vehicle control.


Tire Spinning When stuck in mud, sand, snow, or ice conditions, do not spin your vehicle’s wheels above 35 mph (55 km/h).


See the paragraph on Freeing A Stuck Vehicle in Section 6 of this manual.


WARNING!


Fast spinning tires can be dangerous. Forces gener- ated by excessive wheel speeds may cause tire dam- age or failure. A tire could explode and injure someone. Do not spin your vehicle’s wheels faster than 35 mph (55 km/h) when you are stuck. And don’t let anyone near a spinning wheel, no matter what the speed.


Tread Wear Indicators Tread wear indicators are in the original equipment tires to help you in determining when your tires should be replaced.


STARTING AND OPERATING 275


These indicators are molded into the bottom of the tread grooves and will appear as bands when the tread depth becomes 1/16 inch (2 mm). When the indicators appear in 2 or more adjacent grooves, the tire should be replaced. Many states have laws requiring tire replacement at this point.


276 STARTING AND OPERATING


Replacement Tires The tires on your new vehicle provide a balance of many characteristics. They should be inspected regularly for wear and correct cold tire inflation pressure. The manu- facturer strongly recommends that you use tires equiva- lent to the originals in size, quality and performance when replacement is needed (see the paragraph on tread wear indicators). Refer to the Tire and Loading Informa- tion placard for the size designation of your tire. The service description and load identification will be found on the original equipment tire. Failure to use equivalent replacement tires may adversely affect the safety, han- dling, and ride of your vehicle. We recommend that you contact your original equipment or an authorized tire dealer with any questions you may have on tire specifi- cations or capability.


WARNING!


• Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combinations of unapproved tires and wheels may change suspen- sion dimensions and performance characteristics, resulting in changes to steering, handling, and brak- ing of your vehicle. This can cause unpredictable handling and stress to steering and suspension com- ponents. You could lose control and have an accident resulting in serious injury or death. Use only the tire and wheel sizes with load ratings approved for your vehicle. • Never use a tire with a smaller load index or capacity, other than what was originally equipped on your vehicle. Using a tire with a smaller load index could result in tire overloading and failure. You could lose control and have an accident. • Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control.


CAUTION!


Replacing original tires with tires of a different size may result in false speedometer and odometer read- ings.


Alignment And Balance Poor suspension alignment may result in: • Fast tire wear. • Uneven tire wear, such as feathering and one-sided • Vehicle pull to right or left.


wear.


STARTING AND OPERATING 277


Tires may also cause the vehicle to pull to the left or right. Alignment will not correct this condition. See your dealer for proper diagnosis. Improper alignment will not cause vehicle vibration. Vibration may be a result of tire and wheel out-of- balance. Proper balancing will reduce vibration and avoid tire cupping and spotty wear.


SUPPLEMENTAL TIRE PRESSURE INFORMATION A light load vehicle condition is defined as two passen- gers {150 lbs (68 kg) each} plus 200 lbs (91kg) of cargo. Cold tire inflation pressures for a lightly loaded vehicle will be found on a “Supplemental Tire Pressure Inflation” label located on the face of the driver’s door or in the Tire Information Pressures pamphlet in the glove box.


278 STARTING AND OPERATING


TIRE CHAINS Use “Class S” chains on 1500 Ram Trucks, or other traction aids that meet SAE Type “S” specifications. Use “Class U” chains on 2500/3500 Ram Trucks, or other traction aids that meet SAE Type “U” specifications. NOTE: Chains must be the proper size for the vehicle, as recommended by the chain manufacturer.


CAUTION!


To avoid damage to your vehicle, tires or chains, observe the following precautions:


• Because of limited chain clearance between tires and other


driving about 1/2 mile (0.8 km).


suspension components, it is important that only chains in good condition are used. Broken chains can cause serious vehicle damage. Stop the vehicle immediately if noise occurs that could suggest chain breakage. Remove the damaged parts of the chain before further use.


• Install chains as tightly as possible and then retighten after • Do not exceed 45 mph (72 km/h). • Drive cautiously and avoid severe turns and large bumps, • Do not install tire chains on front wheels of 4x2 vehicles. • Do not drive for a prolonged period on dry pavement. • Observe the tire chain manufacturer’s instructions on


especially with a loaded vehicle.


method of installation, operating speed, and conditions for usage. Always use the lower suggested operating speed of the chain manufacturer if different than the speed recom- mended by the manufacturer.


These cautions apply to all chain traction devices, includ- ing link and cable (radial) chains. Tire chain use is permitted only on the rear tires of Ram 4X2 trucks. NOTE: The use of class “S” chains is permitted on 1500
Ram Trucks with P245/70R17 tires only. NOTE: The use of class “U” chains is permitted on the front and rear of 4X4, 2500 Ram Trucks with LT245/ 70R17E tires. NOTE: The use of class “U” chains is permitted on the front and rear of 4X4, 3500 Ram Trucks with Dual Rear Wheels and LT235/80R17E tires. NOTE: On 4X2 2500/3500 Ram Trucks, class “U” snow chains are permitted on the rear wheels only of vehicles equipped with LT245/70R17, LT265/70R17, and LT235/ 80R17 size tires.


STARTING AND OPERATING 279


NOTE: On 4x4 2500/3500 SRW (Single Rear Wheel) Ram Trucks, class “U” snow chains are permitted on the rear wheels only of vehicles equipped with LT265/ 70R17E.


CAUTION!


Do not use tire chains on 4x4 Ram trucks equipped with P265/70R17, LT275/70R17, P275/60R20, or P275/ 55R20 tires. There may not be adequate clearance for the chains and you are risking structural or body damage to your vehicle. Do not use tire chains on the 4X2 front wheels of 2500/3500 SRW (Single Rear Wheels) equipped with LT245/70R17, LT265/70R17
LT235/80R17 tires or 4X4 front wheels of Ram Trucks equipped with LT265/70R17E. There may not be adequate clearance for the chains and you are risking structural or body damage to your vehicle.


280 STARTING AND OPERATING


SNOW TIRES Snow tires should be of the same size and type construc- tion as the front tires. Consult the manufacturer of the snow tire to determine any maximum vehicle speed requirement associated with the tire. These tires should always be operated at the vehicle maximum capacity inflation pressures under any load condition. While studded tires improve performance on ice, skid and traction capability on wet or dry surfaces may be poorer than that of non-studded tires. Some states pro- hibit studded tires; local laws should be checked before using these tire types.


therefore,


TIRE ROTATION RECOMMENDATIONS Tires on the front and rear axles of vehicles operate at different loads and perform different steering, driving, and braking functions. For these reasons, they wear at unequal rates, and develop irregular wear patterns. These effects can be reduced by timely rotation of tires. The benefits of rotation are especially worthwhile with aggressive tread designs such as those on On/Off Road type tires. Rotation will increase tread life, help to main- tain mud, snow, and wet traction levels, and contribute to a smooth, quiet ride. Follow the recommended tire rotation frequency for your type of driving found in the “Maintenance Schedules” Section of this manual. More frequent rotation is permis- sible if desired. The reasons for any rapid or unusual wear should be corrected prior to rotation being per- formed.


STARTING AND OPERATING 281


Dual Rear Wheels


NOTE: On Canadian vehicles only, if your Ram truck is equipped with All-Season type tires on the front and ON/OFF Road type tires mounted on the rear, do not use a front to back rotation pattern. Instead, rotate your tires side to side at the recommended intervals.


The tires used on dual wheel assemblies should be matched for wear to prevent overloading one tire in a set. To check if tires are even, lay a straight edge across all four tires. The straight edge should touch all the tires.


282 STARTING AND OPERATING


CAUTION!


3500 Dual Rear Tires have only one approved direc- tion of rotation. This is to accommodate the asym- metrical design (tread pattern) of the ON/OFF road tire and the use of Outline White Letter (OWL) tires. • When replacing a flat, the spare tire may have to be remounted on the rim or installed at a different location to maintain the correct placement of the tire on the wheel relative to the tire/wheel posi- tion on the truck. For example, if the spare is used to replace an outer rear tire it will have to be remounted on the rim so that the wheel is dished inward. That way the tread design of asymmetri- cal tires and the white writing of the OWL tires will maintain proper position.


FUEL REQUIREMENTS


All engines (except 5.7L engines) are de- signed to meet all emissions regulations and provide excellent fuel economy and performance when using high quality un- leaded “regular” gasoline having an oc- tane rating of 87. The routine use of pre- mium gasoline is not recommended. Under normal conditions the use of premium fuel will not provide a benefit over high quality regular gasolines and in some circumstances may result in poorer perfor- mance.


3.7L/4.7L Engines


The 5.7L engine is designed to meet all emissions regulations and provide satisfac- tory fuel economy and performance when using high quality unleaded gasoline hav- ing an octane range of 87 to 89. The manu- facturer recommends the use of 89 octane for optimum performance.The routine use


5.7L Engines


of premium gasoline is not recommended. The use of premium gasoline will provide no benefit over high quality regular and mid-grade gasolines, and in some circumstances may result in poorer performance. Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is required. Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experience these symptoms, try another brand of “regular” gasoline be- fore considering service for the vehicle. Over 40 auto manufacturers world-wide have issued and endorsed consistent gasoline specifications (the World- wide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, performance


STARTING AND OPERATING 283


and durability for your vehicle. We recommend the use of gasolines that meet the WWFC specifications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Reformulated Gasoline.” Reformulated gasolines contain oxygenates, and are spe- cifically blended to reduce vehicle emissions and im- prove air quality. We strongly support the use of reformulated gasolines. Properly blended reformulated gasolines will provide excellent performance and durability for the engine and fuel system components.


284 STARTING AND OPERATING


Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxy- genates such as 10% ethanol, MTBE and ETBE. Oxygen- ates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.


CAUTION!


DO NOT use gasolines containing METHANOL. Gasoline containing methanol may damage critical fuel system components.


MMT In Gasoline MMT is a manganese-containing metallic additive that is blended into some gasoline to increase octane. Gasolines blended with MMT provide no performance advantage beyond gasolines of the same octane number without MMT. Gasolines blended with MMT reduce spark plug life and reduce emission system performance. We recom- mend that gasolines free of MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump; therefore, you should ask your gaso- line retailer whether or not his/her gasoline contains MMT. It is even more important to look for gasolines without MMT in Canada because MMT can be used at levels higher than allowed in the United States. MMT is pro- hibited in Federal and California reformulated gasolines.


Materials Added To Fuel All gasolines sold in the United States are required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions and would result in unnecessary cost. There- fore, you should not have to add anything to the fuel. ADDING FUEL


If fuel is poured from a portable container, the NOTE: container should have a flexible nozzle long enough to extend into the fuel filler tube.


CAUTION!


To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.


STARTING AND OPERATING 285


NOTE: When the fuel nozzle “clicks” or shuts off, the fuel tank is full. NOTE: Tighten the gas cap until you hear a “clicking” sound. This is an indication that the gas cap is properly tightened. Make sure that the gas cap is tightened each time the vehicle is refueled.


WARNING!


A fire may result if gasoline is pumped into a portable container that is inside of a vehicle or on a truck bed. You could be burned. Always place gas containers on the ground while filling.


CAUTION!


Damage to the fuel system or emission control system could result from using an improper fuel tank filler tube cap (gas cap). A poorly fitting cap could let impurities into the fuel system.


286 STARTING AND OPERATING


Fuel Filler Cap (Gas Cap) The gas cap is behind the fuel filler door. If the gas cap is lost or damaged, be sure the replacement cap is for use with this vehicle. NOTE: After fuel is added, the vehicle diagnostic sys- tem can determine if the fuel filler cap is loose, improp- erly installed, or damaged. A loose fuel filler cap message will be displayed in the instrument cluster. Tighten the gas cap until a ⬙clicking⬙ sound is heard. This is an indication that the gas cap is properly tightened. Press the odometer reset button to turn the message off. If the problem persists, the message will appear the next time the vehicle is started. This might indicate a damaged cap. If the problem is detected twice in a row, the system will turn on the Malfunction Indicator Light (MIL). Resolving the problem will turn the MIL light off.


WARNING!


• Remove the fuel tank filler tube cap (gas cap) slowly to prevent fuel spray from the filler neck which may cause injury. • The volatility of some gasolines may cause a buildup of pressure in the fuel tank that may increase while you drive. This pressure can result in a spray of gasoline and/or vapors when the cap is removed from a hot vehicle. Removing the cap slowly allows the pressure to vent and prevents fuel spray. • Never allow any lit smoking materials near the vehicles while removing the cap or filling the tank. • Never add fuel to the vehicle when the engine is


running.


STARTING AND OPERATING 287


Fuel System Cautions


CAUTION!


Follow these guidelines to maintain your vehicle’s performance: • The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine performance, damage the emission control system. • An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your dealer for service assistance.


288 STARTING AND OPERATING


• When pulling a heavy load or driving a fully loaded vehicle when the humidity is low and the temperature is high, use a premium unleaded fuel to help prevent spark knock. If spark knock persists, lighten the load, or engine piston damage may result. • The use of fuel additives which are now being sold as octane enhancers is not recommended. Many of these products contain high concentrations of methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is not the responsibility of the manufacturer.

Carbon Monoxide Warnings


WARNING!


Carbon monoxide (CO) in exhaust gases is deadly. Follow the precautions below to prevent carbon monoxide poisoning: • Do not inhale exhaust gases. They contain carbon monoxide, a colorless and odorless gas which can kill. Never run the engine in a closed area, such as a garage, and never sit in a parked vehicle with the engine running for an extended period. If the vehicle is stopped in an open area with the engine running for more than a short period, adjust the ventilation system to force fresh, outside air into the vehicle.


• Guard against carbon monoxide with proper mainte- nance. Have the exhaust system inspected every time the vehicle is raised. Have any abnormal conditions repaired promptly. Until repaired, drive with all side windows fully open. • Keep the liftgate closed when driving your vehicle to prevent carbon monoxide and other poisonous ex- haust gases from entering the vehicle.


FLEXIBLE FUEL—(Fleet Vehicles Only)


E-85 General Information The information in this section is for Flexible Fuel ve- hicles only. These vehicles can be identified by the unique fuel filler door label that states Ethanol (E-85) or Un- leaded Gasoline Only. This section only covers those subjects that are unique to these vehicles. Please refer to the other sections of this manual for information on features that are common between Flexible Fuel and gasoline only powered vehicles.


STARTING AND OPERATING 289


CAUTION!


Only vehicles with the E-85 fuel filler door label can operate on E-85.


ETHANOL FUEL (E-85) E-85 is a mixture of approximately 85% fuel ethanol and 15% unleaded gasoline.


WARNING!


Ethanol vapors are extremely flammable and could cause serious personal injury. Never have any smok- ing materials lit in or near the vehicle when remov- ing the fuel filler tube cap (gas cap) or filling the tank. Do not use E-85 as a cleaning agent and never use it near an open flame.


290 STARTING AND OPERATING


Fuel Requirements Your vehicle will operate on both unleaded gasoline with an octane rating of 87, or E-85 fuel, or any mixture of these two. For best results, a refueling pattern that alternates be- tween E-85 and unleaded gasoline should be avoided. When you do switch fuels, it is recommended that • you do not switch when the fuel gauge indicates less • you do not add less than 5 gallons when refueling • you operate the vehicle immediately after refueling for


than 1/4 full


a period of at least 5 minutes


Observing these precautions will avoid possible hard starting and/or significant deterioration in drivability during warm up.


NOTE: When the ambient temperature is above 90°F, you may experience hard starting and rough idle follow- ing start up even if the above recommendations are followed. Selection Of Engine Oil For Flexible Fuel Vehicles (E-85) and Gasoline Vehicles Whether operating the vehicle on an E-85 ethanol fuel or unleaded gasoline the engine oil requirements are the same. Refer to the “Maintenance Procedures” section of this manual for the proper quality and viscosity engine oil. (See page 355 for more information.) Starting The characteristics of E-85 fuel make it unsuitable for use when ambient temperatures fall below 0°F. In the range of 0°F to 32°F, you may experience an increase in the time it takes for your engine to start, and a deterioration in drivability (sags and/or hesitations) until the engine is fully warmed up.


Cruising Range Because E-85 fuel contains less energy per gallon than gasoline, you will experience an increase in fuel con- sumption. You can expect your MPG and your driving range to decrease by about 30% compared to gasoline operation. Replacement Parts Many components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that your vehicle is serviced with correct ethanol com- patible parts.


CAUTION!


Replacing fuel system components with non-ethanol compatible components can damage your vehicle.


STARTING AND OPERATING 291


Maintenance If you operate the vehicle using E-85 fuel, follow Sched- ule B in the maintenance schedule section of this manual.


CAUTION!


Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect driveability.


CATALYTIC CONVERTER The catalytic converter requires the use of unleaded fuel only. Leaded gasoline will destroy the effectiveness of the catalyst as an emission control device. Under normal operating conditions, the catalytic converter will not require maintenance. However, you must keep the en- gine maintained to assure proper operation and prevent possible damage.


292 STARTING AND OPERATING


NOTE: systems can result against you.


Intentional tampering with emissions control in civil penalties being assessed


CAUTION!


Damage to the catalytic converter can result if your vehicle is not kept in proper operating condition. In the event of engine malfunction, particularly involv- ing engine misfire or other apparent loss of perfor- mance, have your vehicle serviced promptly. Contin- ued operation of your vehicle with a severe malfunction could cause the converter to overheat, resulting in possible damage to the converter and vehicle.


As with any vehicle, do not park or operate this vehicle in areas where combustible materials such as grass or leaves can come in contact with a hot exhaust system.


A scorching odor may be detected if you continue to run a malfunctioning engine. The odor may indicate severe and abnormal catalyst overheating. If this occurs, the vehicle should be stopped, the engine shut off and the vehicle allowed to cool. Service, including a tune-up to manufacturer’s specifications should be obtained imme- diately. To minimize the possibility of catalyst damage: • Do not try to start the engine by pushing or towing the • Do not idle the engine with any spark plug wires • Do not idle the engine for prolonged periods during very rough idle or malfunctioning operating condi- tions.

• Do not allow vehicle to run out of fuel.


VEHICLE LOADING


Certification Label As required by National Highway Traffic Safety Admin- istration Regulations, your vehicle has a certification label affixed to the driver’s side door or pillar. This label contains the month and year of manufacture, Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR) front and rear, and Vehicle Identification Number (VIN). A Month-Day-Hour (MDH) number is included on this label and indicates the Month, Day and Hour of manufacture. The bar code that appears on the bottom of the label is your Vehicle Identification Number (VIN). Gross Vehicle Weight Rating (GVWR) The GVWR is the total permissible weight of your vehicle including driver, passengers, vehicle, options and cargo. The label also specifies maximum capacities of front and


STARTING AND OPERATING 293


rear axle systems (GAWR). Total load must be limited so GVWR and front and rear GAWR are not exceeded. Payload The payload of a vehicle is defined as the allowable load weight a truck can carry, including the weight of the driver, all passengers, options and cargo. Gross Axle Weight Rating (GAWR) The GAWR is the maximum permissible load on the front and rear axles. The load must be distributed in the cargo area so that the GAWR of each axle is not exceeded. Each axle GAWR is determined by the components in the system with the lowest load carrying capacity (axle, springs, tires or wheels). Heavier axles or suspension components sometimes specified by purchasers for in- creased durability does not necessarily increase the vehi- cle’s GVWR.


294 STARTING AND OPERATING


Tire Size This is the minimum allowable tire size for your vehicle. Replacement tires must be equal to the load capacity of this tire size. Rim Size This is the rim size that is appropriate for the tire size listed. Inflation Pressure This is the cold tire inflation pressure for your vehicle for all loading conditions up to full GAWR. Curb Weight The curb weight of a vehicle is defined as the total weight of the vehicle with all fluids, including vehicle fuel, at full capacity conditions, and with no occupants or cargo loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a commercial scale before any occupants or cargo are added.


Loading The actual total weight and the weight of the front and rear of your vehicle at the ground can best be determined by weighing it when it is loaded and ready for operation. The entire vehicle should first be weighed on a commer- cial scale to insure that the GVWR has not been exceeded. The weight on the front and rear of the vehicle should then be determined separately to be sure that the load is properly distributed over front and rear axle. Weighing the vehicle may show that the GAWR of either the front or rear axles has been exceeded but the total load is within the specified GVWR. If so, weight must be shifted from front to rear or rear to front as appropriate until the specified weight limitations are met. Store the heavier items down low and be sure that the weight is distributed equally. Stow all loose items securely before driving.


STARTING AND OPERATING 295


NOTE: The weights shown in this chart are not necessarily the weights for your vehicle. Also, the amount of load added to both the front and rear axles can be computed after the vehicle has been weighed both in its ⴖcurb weightⴖ condition, and in its ⴖloaded and ready for operationⴖ condition. Gross Vehicle Weight Rating (GVWR) 6500 LBS.


Improper weight distributions can have an adverse effect on the way your vehicle steers and handles and the way the brakes operate.


CAUTION!


Do not load your vehicle any heavier than the GVWR or the maximum front and rear GAWR. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. This could cause you to lose control. Also overloading can shorten the life of your vehicle.


An EXAMPLE of a loaded vehicle is shown in the following chart. Note that neither GVWR nor GAWR capabilities are exceeded. Overloading can cause poten- tial safety hazards and shorten service life.


296 STARTING AND OPERATING


TRAILER TOWING All Dodge Ram Pickup trucks are intended to tow trailers up to 2,000 lbs (907 kg) without added equipment or alterations to standard equipment. Your vehicle may be factory equipped for safe towing of trailers weighing over 2,000 lbs (907 kg) with the optional Trailer Tow Prep Package. See your Dodge dealer for package content. Definitions The following trailer towing related terminology defini- tions will assist in understanding the subsequent sec- tions: GROSS COMBINATION WEIGHT RATING (GCWR) is the total permissible weight of your vehicle and trailer when weighed in combination. (Note that GCWR ratings include a 150 lb (68 kg) allowance for the presence of a driver.) Tongue Weight (of a trailer) is the weight placed on a vehicle’s trailer hitch by the trailer.


GROSS TRAILER WEIGHT (GTW) is the weight of the trailer plus the weight of all cargo, consumables and equipment (permanent or temporary) loaded in or on the trailer in its ⬙loaded and ready for operation⬙ condition. TRAILER SWAY CONTROL is a telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable friction associ- ated with the telescoping motion to dampen any un- wanted trailer swaying motions while traveling.


CAUTION!


• During the first 500 miles (805 km) your new vehicle is driven, do not tow a trailer. Doing so may damage your vehicle. • When first towing a trailer, limit your speed to 50
mph (80 km/h) during the first 500 miles (805 km) of towing.


Consider the following items when computing the weight on the rear axle: • the tongue weight of the trailer • the weight of any other type of cargo or equipment put


in or on your vehicle


NOTE: Remember that everything put into or on the trailer adds to the load on your vehicle. Also, additional factory-installed options, or dealer-installed options, must be considered as part of the total load on your vehicle. Refer to the Certification label located at the driver’s door for the Gross Vehicle Weight Rating.


WARNING!


Improper towing can lead to an injury accident. Follow these guidelines to make your trailer towing as safe as possible:


STARTING AND OPERATING 297


Perform the maintenance listed in the “Maintenance Schedules” section of this manual (Section 8). When towing a trailer, never exceed the Gross Axle Weight Rating (GAWR), or Gross Combined Vehicle Weight (GCVW).


CAUTION!


When hauling cargo or towing a trailer, do not overload your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transmission, steering, sus- pension, body structure or tires.

Axle Lubricant and Trailer Towing


1500 Models • 1500 Model rear axles are trailer tow ready. Limited slip rear axles on 1500 models require the use of a limited slip additive (refer to the “Recommended Fluids, Lubricants, and Genuine Parts” section.) • The limited slip additive is included with the factory • If the axle fluid is changed, 4 oz.

vehicle and trailer.


Trailer Towing Recommendations • All trailer hitches should be professionally installed on • Safety chains must always be used between your • Do not interconnect the hydraulic brake system or vacuum system of your vehicle with that of the trailer. This could cause inadequate braking and possible personal injury. An electrically–actuated electric trailer brake controller is recommended. • Trailer brakes are recommended for trailers over 1000
lbs (454 kg) and are required for trailers in excess of 2,000 lbs (907 kg) • Use an approved wiring harness connector on the trailer. Standard equipment on all RAM pickup mod- els provides a 4-way trailer tow connector located


under the bumper. This connector contains the follow- ing vehicle circuits: park/tail lamps, left stop/turn lamp, right stop/turn lamp, and ground. With the optional Trailer Tow Prep package a 7-way connector is provided with the following additional circuits: backup lamp, trailer battery and electric brake.


NOTE: Connect trailer lighting and brakes using factory harnesses only. Do not cut or splice wiring to the brake circuits. • Be sure the trailer is loaded heavier in front, with 60% to 65% of the weight in front of the axle(s). Loads balanced over the wheels or heavier in the rear can cause the trailer to sway severely side to side which will cause loss of control of vehicle and trailer. Failure to load trailers heavier in front is the cause of many trailer accidents. (For a ⬙5th Wheel⬙ style trailer, this range of loading on the ⬙King Pin⬙ should be between 15% and 25%.)


STARTING AND OPERATING 299


• Make certain that the load is secured in the trailer and will not shift during travel. When towing cargo such as livestock, dynamic load shifts can occur that require the driver to maintain attention.


Trailer Towing — Hitches With a Class I Hitch, your vehicle can be equipped to tow trailers with a Gross Trailer Weight (GTW) of 2,000 lbs (907 kg) maximum. With a Class II Hitch, your vehicle can be equipped to tow trailers with a Gross Trailer Weight (GTW) of 3,500
