Tow Haul O/D Off Switch

When driving in hilly areas, towing a trailer, carrying a heavy load, etc., and frequent transmission shifting oc- curs, press the “TOW HAUL O/D OFF” button once to select TOW HAUL. This will improve performance and

STARTING AND OPERATING 311

reduce the potential for transmission overheating or failure due to excessive shifting. When operating in “TOW HAUL” mode, 5th gear (if 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 are performed (for im- proved braking) when driving conditions warrant. Press- ing the “TOW HAUL O/D OFF” button a second time to select O/D OFF will disable 4th and 5th gear completely, which should eliminate any excessive transmission shift- ing. The “TOW HAUL” or “O/D OFF” light will illuminate in the instrument cluster to indicate when the switch has been activated. Pressing the switch a third time restores normal operation. If the “TOW HAUL” or “O/D OFF” modes are desired, the button must be pressed each time the engine is started.

312 STARTING AND OPERATING

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 the upper gears. 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 O/D OFF” button, when the transmission 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 cause damage to the transmission. The torque converter will refill within five seconds of shifting from Park into any other gear position.

MANUAL TRANSMISSION

WARNING!

You or others could be injured if you leave the vehicle unattended without having the parking brake fully applied. The parking brake should al- ways be applied when the driver is not in 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.

STARTING AND OPERATING 313

Manual Transmission — 6 Speed (G56) 2500 and 3500 models are equipped with the G56 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 5th gear ranges. For steady highway driving with light accelerations, 6th 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.

314 STARTING AND OPERATING

To shift into Reverse, come to a complete stop. Depress the clutch and pause briefly to allow the gear train to stop. Reverse has a “crash-through” lockout feature. Move the shift lever from the Neutral position straight across, in one swift motion, and down into Reverse. 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 — 6-Speed (G238) 1500 models are equipped with a G238 manual transmis- sion. This transmission has 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. When launching a stationary vehicle, keep the engine speed low until the clutch is fully engaged. 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 5th to 6th gear, do not apply excessive knob load toward the Reverse gear gate, as you may overpower the Reverse “crash-through” load and unintentionally clash into Re- verse gear. Also, when shifting from 6th to 5th gear, excessive knob load toward the Reverse gear gate will result in blocking of the shift.

You should use first gear when starting from a standing position. Damage to the clutch can result from starting in 2nd or 3rd gear. Use each gear in numerical order – do not skip a gear. To shift into Reverse, come to a complete stop. Depress the clutch and pause briefly to allow the gear train to stop. Reverse has a “crash-through” lockout feature. Move the shift lever from the Neutral position straight across, in one swift motion, and down into Reverse. 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 – All Manual Transmissions 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.

316 STARTING AND OPERATING

CAUTION!

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.

Failure to follow the recommended downshifting speeds may cause the engine to over speed and / or damage the clutch disc even if the clutch pedal is depressed.

To prevent clutch and transmission damage, your vehicle should be downshifted at speeds no greater than those listed in the Maximum Recommended Downshifting Speed chart. Maximum Recommended Downshifting Speeds Gear Selec- tion Maxi- mum Speed

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

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.

STARTING AND OPERATING 317

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.

318 STARTING AND OPERATING

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.

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.

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).

STARTING AND OPERATING 319

Shifting Procedure - Manually Shifted Transfer Case

Manual Transfer Case Shifter

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

320 STARTING AND OPERATING

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.

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.

Electronically Shifted Transfer Case Operating Information/Precautions (5 Position Switch)—If Equipped

5 Position Switch

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.

STARTING AND OPERATING 321

This Electronically Shifted transfer case provides 5 mode positions: 2 wheel drive (2WD), 4WD AUTO, 4WD HI, Neutral and 4WD Lo. The Electronically Shifted transfer case is designed to be driven in the 2 wheel drive position (2WD) or 4 wheel drive position (4WD AUTO) for normal street and high- way conditions (dry hard surfaced roads). Driving the vehicle in 2WD will have greater fuel economy benefits, as the front axle is not engaged in 2WD. For variable driving conditions the 4WD AUTO mode can be used. In this mode the front axle is engaged, but the vehicle’s power is sent to the rear wheels. Four wheel drive will be automatically engaged when the vehicle senses a loss of traction. Because the front axle is en- gaged, this mode will result in lower fuel economy than the 2WD mode.

322 STARTING AND OPERATING

When additional traction is required, the transfer case 4WD HI and 4WD LO 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 4WD HI and 4WD LO positions are designed for loose, slippery road surfaces only. Driving in the 4WD HI and 4WD LO positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components.

Neutral Button

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 instrument cluster and indicate the current and desired transfer case selection. When you select a different trans- fer case position, the indicator lights will do the follow- ing: 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.

STARTING AND OPERATING 323

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. 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.

324 STARTING AND OPERATING

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.

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. This could cause damage to driveline components.

When operating your vehicle in 4WD LO, the engine speed is approximately three times that of the 2WD, 4WD AUTO or 4WD HI 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 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.

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 ⇔ 4 AUTO or 4 HI Rotate the 4WD Control Switch to the desired position. Shifts between 2WD and 4WD AUTO and 4WD HI can be done with the vehicle stopped or in motion. With the vehicle in motion, the transfer case will engage / disen- gage faster if you momentarily release the accelerator pedal after turning the control switch. If the vehicle is

STARTING AND OPERATING 327

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. 2WD or 4 AUTO or 4 HI ⇔ 4 LO NOTE: When shifting into or out of 4WD LO 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).

328 STARTING AND OPERATING

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.”

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. 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.

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.

DRIVING ON SLIPPERY SURFACES When driving on wet or slushy roads, it is possible for a wedge of water to build up between the tire and road surface. This is known as hydroplaning and may cause partial or complete loss of vehicle control and stopping ability. To reduce this possibility, the following precau- tions should be observed: 1. Slow down during rainstorms or when roads are slushy. 2. Slow down if road has standing water or puddles. 3. Replace tires when tread wear indicators first become visible. 4. Keep tires properly inflated. 5. Maintain sufficient distance between your vehicle and the car in front to avoid a collision in a sudden stop.

STARTING AND OPERATING 337

DRIVING OFF-ROAD Care should be taken when attempting to climb steep hills or driving diagonally across a hill or slope. If natural obstacles force you to travel diagonally up or down a hill, choose a mild angle and keep as little side tilt as possible. Keep the vehicle moving and make turns slowly and cautiously. If you must back down a hill, back straight down using REVERSE gear. Never back down in NEUTRAL, or diagonally across the hill. When driving over sand, mud, and other soft terrain, shift to low gear and drive steadily. Apply the accelerator slowly to avoid spinning the wheels. DO NOT REDUCE the tire pressures for this type of driving.

338 STARTING AND OPERATING

NOTE: After off-road usage, particularly in sand or mud, inspect the underside of the vehicle for accumu- lated dirt at the propeller shaft, axles, U-joints, brake rotors and calipers. Use a hose to clean off any accumulation of dirt or mud. Check the exhaust system and all exposed components for any sign of damage. If you experience unusual vibration after driving in mud, slush or similar conditions, check the wheels for im- pacted material. Impacted foreign material can cause a wheel imbalance. Removing the foreign material from the wheels will correct the situation.

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.

STARTING AND OPERATING 339

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. • Never leave children alone in a vehicle. Leaving children in a vehicle unattended is dangerous for a number of reasons. A child or others could be seriously or fatally injured. 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.

Parking Brake Release

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.

340 STARTING AND OPERATING

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.

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.

STARTING AND OPERATING 341

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.

342 STARTING AND OPERATING

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.

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.

STARTING AND OPERATING 343

POWER STEERING The standard power steering system will give you good vehicle response and increased ease of maneuverability in tight spaces. The system will provide mechanical steering capability if power assist is lost. If for some reason, the power assist is interrupted, it will still be possible to steer your vehicle. Under these condi- tions you will observe a substantial increase in steering effort, especially at very low vehicle speeds and during parking maneuvers. Increased noise levels at the end of the steering NOTE: wheel travel are considered normal and does not indicate that there is a problem with the power steering system. Upon initial start-up in cold weather, the power steering pump may make noise for a short period of time. This is due to the cold, thick fluid in the steering system. This noise should be considered normal, and does not in any way damage the steering system.

344 STARTING AND OPERATING

WARNING!

Continued operation with reduced power steering assist could pose a safety risk to yourself and others. Service should be obtained as soon as possible.

CAUTION!

Prolong operation of the steering system at the end of the steering wheel travel will increase the steering fluid temperature and should be avoided when possible. Damage to the power steering pump may occur.

ELECTRONIC BRAKE CONTROL SYSTEM (ABS/TCS/BAS/HSA/ERM/ESP) – IF EQUIPPED Your vehicle may be equipped with an optional ad- vanced electronic brake control system that includes ABS (Anti-Lock Brake System), TCS (Traction Control Sys- tem), BAS (Brake Assist System), Hill Start Assist (HSA), ERM (Electronic Roll Mitigation) and ESP (Electronic Stability Program). All systems work together to enhance vehicle stability and control in various driving conditions and are commonly referred to as ESP. ABS (Anti-Lock Brake System)

This system aids the driver in maintaining vehicle control under adverse braking conditions. The system controls hydraulic brake pressure to prevent wheel lock-up and help avoid skidding on slippery surfaces during braking. Refer to “Anti-Lock Brake System” in Section 5 of this manual for more information about ABS.

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.

STARTING AND OPERATING 345

TCS (Traction Control System) – if equipped with ESP

This system monitors the amount of wheel spin of each of the driven wheels. If wheel spin is detected, brake pressure is applied to the slipping wheel(s) and engine power is reduced to provide enhanced acceleration and stability. A feature of the TCS system functions similar to a limited slip differential and controls the wheel spin across a driven axle. If one wheel on a driven axle is spinning faster than the other, the system will apply the brake of the spinning wheel. This will allow more engine torque to be applied to the wheel that is not spinning. This feature remains active even if TCS and ESP are in either the “Partial Off” or “ESP Off” modes. Refer to “ESP (Electronic Stability Program)” in this Section of this manual.

346 STARTING AND OPERATING

BAS (Brake Assist System)

ESP Off Button Location

The BAS is designed to optimize the vehicle’s braking capability during emergency braking maneuvers. The system detects an emergency braking situation by sens- ing the rate and amount of brake application and then applies optimum pressure to the brakes. This can help reduce braking distances. The BAS complements the antilock brake system (ABS). Applying the brakes very quickly results in the best BAS assistance. To receive the benefit of the system, you must apply continuous brak- ing pressure during the stopping sequence. Do not reduce brake pedal pressure unless braking is no longer desired. Once the brake pedal is released, the BAS is deactivated.

WARNING!

HSA (Hill Start Assist)

STARTING AND OPERATING 347

• BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded.

• The BAS 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 a BAS-equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

The HSA system is designed to assist the driver in launching a vehicle on an incline. HSA will maintain the level of brake pressure the driver inputs for a short duration once the driver takes his foot off of the brake pedal. If the driver does not apply the throttle during this short duration, the system will release brake pressure and the vehicle will roll down the incline. The system will release brake pressure in proportion to amount of throttle applied.

348 STARTING AND OPERATING

WARNING!

If the clutch pedal (manual vehicles only) remains depressed during the application of the throttle, the HSA will disengage allowing the vehicle will roll down the incline. This could cause a collision with another vehicle or object. To avoid this, do not apply throttle while depressing the clutch pedal until you are ready to release the clutch. Always remember the driver is responsible for braking the vehicle.

HSA Activation Criteria The following criteria must be met in order for HSA to activate: • Vehicle must be stopped • Vehicle must be on a 7% or greater incline

• Gear selection matches vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle back- ing uphill is in reverse gear).

WARNING!

There may be situations on minor hills (i.e., less than 7%), with a loaded vehicle, or while pulling a trailer where the system will not activate and slight rolling may occur, which could cause a collision with an- other vehicle or object. Always remember the driver is responsible for braking the vehicle.

The system will only work if the intended direction of the vehicle and vehicle gear match. For example, if the intended direction is forward up a hill and the vehicle is in drive (automatic equipped vehicle), and the activation criteria are met, HSA will activate.

HSA on Automatic Vehicles The system will work in reverse and all forward gears on vehicles equipped with an automatic transmission. The system will not activate if the vehicle is placed in neutral. HSA on Manual Vehicles The system will work in reverse, forward gears, and neutral on manual transmission equipped vehicles. The system does not recognize neutral on manual vehicles, thus it will hold the vehicle on an incline for a short period while in neutral, regardless of clutch position. To prevent this, do not attempt to roll down a hill simply by putting the transmission in neutral and letting gravity act on the vehicle, as the HSA will prevent the vehicle from rolling. Instead, use the appropriate gear for moving in the desired direction.

STARTING AND OPERATING 349

Towing and Hauling with HSA (Vehicles Equipped with Automatic Transmissions Only) The HSA system does not know if your vehicle is loaded or towing a trailer, unless the “TOW/HAUL” button, located on the transmission gear selector lever, is se- lected. When activated, the “TOW/HAUL” light will illuminate in the instrument cluster. Refer to the “Starting and Operating” Section of this manual for more informa- tion on the “TOW/HAUL” mode. In order to accommo- date the extra weight entailed under towing and hauling conditions and to increase driver comfort while launch- ing on a hill, the system recognizes when the Tow/Haul button is activated and compensates by releasing brake pressure at a slower rate while throttle is applied to in order to prevent the vehicle from rolling down the hill.

350 STARTING AND OPERATING

WARNING!

WARNING!

If you use a trailer brake controller with your trailer, your trailer brakes may be activated and deactivated with the brake switch. If so, when the brake pedal is released there may not be enough brake pressure to hold the vehicle and trailer on a hill and this could cause a collision with another vehicle or object behind you. In order to avoid rolling down the incline while resuming acceleration, manually acti- vate the trailer brake or apply more vehicle brake pressure prior to releasing the brake pedal. Always remember the driver is responsible for braking the vehicle.

HSA is not a parking brake. If you stop the vehicle on a hill without putting the transmission in park or using the parking brake, it will roll down the incline and could cause a collision with another vehicle or object. Always remember to use the parking brake while parking on a hill, and that the driver is responsible for braking the vehicle.

HSA Off If you wish to turn off the HSA system, follow this procedure: 1. Start with the engine off and vehicle in Park (auto- matic transmission) or Neutral with clutch out (manual transmission) with wheels straight. Apply parking brake on manual transmission vehicle. 2. Start the engine.

3. With the engine running, the brake applied, and the clutch out, rotate the steering wheel 180° counter- clockwise from center. 4. Press ESP button four times within twenty seconds. The “ESP/TCS Indicator Light” should appear and dis- appear four times. 5. Rotate the steering wheel 360° clockwise (180° clock- wise from center). 6. Cycle ignition switch OFF then ON. 7. If the sequence was completed properly, the “ESP/ TCS Indicator Light” will blink several times to confirm HSA is off. Steps 1-7 must be completed within 90 seconds to turn off HSA. Repeat steps 1-7 to re-enable HSA functionality.

STARTING AND OPERATING 351

ERM (Electronic Roll Mitigation) This system anticipates the potential for wheel lift by monitoring the driver’s steering wheel input and the speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicles speed are sufficient to potentially cause wheel lift, it applies the appropriate brake and may reduce engine power to lessen the chance that wheel lift will occur. ERM will only intervene during very severe or evasive driving maneu- vers. ERM can only reduce the chance of wheel lift occurring during severe or evasive driving maneuvers. It can not prevent wheel lift due to other factors such as road conditions, leaving the roadway or striking objects or other vehicles.

352 STARTING AND OPERATING

WARNING!

Many factors, such as vehicle loading, road condi- tions and driving conditions, influence the chance that wheel lift or rollover may occur. ERM can not prevent all wheel lift or rollovers, especially those that involve leaving the roadway or striking objects or other vehicles. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of an ERM-equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopar- dize the user’s safety or the safety of others.

ESP (Electronic Stability Program)

This system enhances directional control and stability of the vehicle under various driving conditions. ESP cor- rects for over/under steering of the vehicle by applying

the brake of the appropriate wheel to assist in counter- acting the over/under steer condition. Engine power may also be reduced to help the vehicle maintain the desired path. ESP uses sensors in the vehicle to determine the vehicle path intended by the driver and compares it to the actual path of the vehicle. When the actual path does not match the intended path, ESP applies the brake of the appropri- ate wheel to assist in counteracting the oversteer or understeer condition. • Oversteer - when the vehicle is turning more than • Understeer - when the vehicle is turning less than

appropriate for the steering wheel position.

ESP/TCS Indicator Light

The “ESP/TCS Indicator Light” located in the instrument cluster, starts to flash as soon as the tires lose traction and the ESP system becomes active. The “ESP/TCS Indicator Light” also flashes when TCS is active. If the “ESP/TCS Indicator Light” begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.

STARTING AND OPERATING 353

WARNING!

• ESP (Electronic Stability Program) cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. • ESP cannot prevent accidents, including those resulting from excessive speed in turns, driving on slippery surfaces, or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. • The capabilities of an ESP-equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.

354 STARTING AND OPERATING

The ESP system has multiple operating modes depend- ing on vehicle type – Two Wheel Drive (2WD) or Four Wheel Drive (4WD). 4WD vehicles may be equipped with either a four mode position (2WD/Neutral/4HI/ 4LO) transfer case or a five mode position (2WD/Auto/ Neutral/4H/4LO) transfer case. If you have a 4WD vehicle, refer to the Four Wheel Drive Operating Section to determine which transfer case is on your vehicle and how to operate it. All 2WD vehicles and 4WD vehicles in 2WD, Auto or 4HI Modes can choose the following ESP operating modes:

ESP On This is the normal operating mode for ESP in 2WD/ Auto/4HI Modes and in 2WD vehicles. Whenever the vehicle is started or the transfer case (if equipped) is shifted from 4LO or neutral back to 4HI or Auto, the ESP system will be in this mode. This mode should be used

for almost all driving situations. ESP should only be turned to “Partial Off” or “ESP Off” for specific reasons as noted below.

This mode is entered by momentarily depressing the “ESP Control Switch”. When in “Partial Off” mode, the TCS portion of ESP, except for the “limited slip” feature described in the TCS sec- tion, has been disabled and the “ESP/ TCS Indicator Light” will be illumi- nated. All other features of ESP function normally, with the exception of engine power reduction. Engine power is not reduced in this mode. This mode is intended to be used if the vehicle is in deep snow, sand or gravel conditions and more wheel spin than ESP would nor- mally allow is required to gain traction. To turn ESP on again, momentarily depress the “ESP Control Switch”. This will restore the normal “ESP On” mode of operation.

NOTE: To improve the vehicle’s traction when driving with snow chains, or starting off in deep snow, sand or gravel, it may be desirable to switch to the “Partial Off” mode by pressing the ESP switch. Once the situation requiring ESP to be switched to the “Partial Off” mode is overcome, turn ESP back on by momentarily depressing the “ESP Control Switch”. This may be done while the vehicle is in motion.

WARNING!

In the Partial Off mode, the engine torque reduction and stability features are desensitized. Therefore, the enhanced vehicle stability offered by ESP is unavailable.

STARTING AND OPERATING 355

All 4WD vehicles in Auto and 4HI Modes can also choose the following ESP operating mode. This is the only ESP operating mode in 4LO:

ESP Off This mode is intended for off-road use when ESP stability features could inhibit vehicle maneuverability due to trail conditions. This mode is entered by depressing and holding the “ESP Control Switch” for 5 seconds when the vehicle is stopped and the engine is running. After 5
seconds, the “ESP/TCS Indicator Light” will illuminate and the “ESP Off” message will appear in the odometer. Press and release the trip odometer button located on the instrument cluster to clear this message. In this mode, ESP and TCS, except for the “limited Slip” feature described in the TCS section, are turned off until the vehicle reaches a speed of 40 mph (64 km/h). At 40
mph (64 km/h) the system returns to “Partial Off” mode, described above. When the vehicle speed drops below 35

356 STARTING AND OPERATING

mph (56 km/h) the ESP system shuts off. ESP is off at low vehicle speeds sao that it will not interfere with off-road driving but ESP function returns to provide the stability feature at speeds above 40 mph (64 km/h). The “ESP/ TCS Indicator Light” will always be illuminated when ESP is off. To turn ESP on again, momentarily depress the “ESP Control Switch”. This will restore the normal “ESP On’ mode of operation. “ESP Off” is the only operating mode for ESP in 4LO. Whenever the vehicle is started in 4LO or the transfer case (if equipped) is shifted from 4HI or neutral to 4LO, the ESP system will be in this mode.

WARNING!

With the ESP switched off, the enhanced vehicle stability offered by ESP is unavailable. In an emer- gency evasive maneuver, the ESP system will not engage to assist in maintaining stability. “ESP Off” mode is intended for off-highway or off-road use, only.

ESP/BAS Warning Lamp and ESP/TCS Indicator Light The malfunction indicator for the ESP is combined with the BAS indicator. The yellow “ESP/BAS Warning Lamp” and the yellow “ESP/TCS Indicator Light” in the instrument cluster both come on when the ignition switch is turned to the “ON” position. They should both go out with the engine running. If the “ESP/BAS Warn- ing Lamp” comes on continuously with the engine running, a malfunction has been detected in either the

3) the tire size designed for your vehicle 4) the cold tire inflation pressures for the front, rear and spare tires. 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 in the “Vehicle Loading” sec- tion 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, refer to 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 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.

364 STARTING AND OPERATING

passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (since 5 x 150 = 750, and 1400 – 750 = 650 lbs.) 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 capaci- ties of your vehicle with varying seating configurations and number and size of occupants.

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 chuckholes can cause damage that result 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 recommended cold tire inflation pressure.

2. Economy— Improper inflation pressures can cause uneven wear pat- terns to develop across the tire tread. These abnormal wear patterns will reduce tread life resulting in a need for earlier tire replacement. Under inflation, 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. Over inflation produces a jarring and uncomfortable ride. Tire Inflation Pressures The proper cold tire inflation pressure is listed either on the face of the driver’s door or on the driver’s side “B” pillar. Some vehicles may have Supplemental Tire Pressure Information for vehicle loads that are less than the maximum loaded vehicle condition. These pressure con- ditions will be found in the “Supplemental Tire Pressure Information” section of this manual.

STARTING AND OPERATING 367

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 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.

368 STARTING AND OPERATING

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 1 mile (1 km) after a 3 hour period. The cold tire inflation pressure must not exceed the maximum inflation pres- sure molded into the tire sidewall. 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

STARTING AND OPERATING 369

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.

Radial-Ply Tires

WARNING!

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).

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.

370 STARTING AND OPERATING

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.

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.

WARNING!

CAUTION!

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 the tread is worn to the tread wear indicators, 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.

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.

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 the vehicle at the first opportunity.

STARTING AND OPERATING 371

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). Refer to the paragraph on “Freeing A Stuck Vehicle” in Section 6 of this manual.

372 STARTING AND OPERATING

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 30 mph (48 km/h) for more than 30 seconds continuously 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.

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

Life of Tire The service life of a tire is dependent upon varying factors including but not limited to: • Driving style • Tire pressure • Distance driven

WARNING!

Tires and spare tire should be replaced after six years, regardless of the remaining tread. Failure to follow this warning can result in sudden tire failure. You could lose control and have an accident result- ing in serious injury or death.

STARTING AND OPERATING 373

Keep dismounted tires in a cool, dry place with as little exposure to light as possible. Protect tires from contact with oil, grease, and gasoline. 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 (refer to the paragraph on “Tread Wear Indicators”). Refer to the “Tire and Loading Information” 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, handling, and ride of your vehicle. We recommend that you contact your original equipment or an autho- rized tire dealer with any questions you may have on tire specifications or capability.

374 STARTING AND OPERATING

WARNING!

• Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combinations of un- approved tires and wheels may change suspension dimensions and performance characteristics, resulting in changes to steering, handling, and braking of your vehicle. This can cause unpredictable handling and stress to steering and suspension components. 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 ad- equate 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. 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.

wear.

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 – IF EQUIPPED 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 the face of the driver’s door.

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.

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

376 STARTING AND OPERATING

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.

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, 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.

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.

378 STARTING AND OPERATING

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.

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.

Dual Rear Wheels

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.

STARTING AND OPERATING 379

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 perfor- mance when using high quality unleaded “regular” gasoline having an octane rating of 87. The routine use of premium gasoline is not recommended. Under normal condi- tions the use of premium fuel will not provide a benefit over high quality regular gasolines and in some circum- stances may result in poorer performance.

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 of premium gasoline is not recommended. The use of
