The blower will increase in speed and transition into Auto mode and DELAY will no longer be illuminated in the display. The
286 UNDERSTANDING YOUR INSTRUMENT PANEL blower will engage immediately if the Defrost mode is selected, or by adjusting the blower control knob and setting the fan to any fixed speed. Manual Operation This system offers a full complement of manual override features. NOTE: Each of these features operate independently from each other. If any one feature is controlled manually, the temperature doors will continue to operate automati- cally.
There are six fixed blower speeds. Use this control to regulate the amount of air forced through the system in any mode you select. The blower speed increases as you move the control clockwise from the OFF position.
Blower Control
The blower fan speed can be set to any fixed speed by adjusting the blower control knob. The fan will now operate at a fixed speed until additional speeds are selected. This allows the front occupants to control the volume of air circulated in the vehicle and cancel the Auto mode. The operator can also select the direction of the airflow by selecting one of the following positions. Panel Mode
Air comes from the outlets in the instrument panel. Each of these outlets can be individually adjusted to direct the flow of air. The air vanes of the center outlets and outboard outlets can be rotated to regulate or shut off the airflow from these outlets. Bi-Level Mode
Air comes from the instrument panel outlets, floor outlets and defrost outlets.
In many temperature positions, the BI-LEVEL NOTE: mode is designed to provide cooler air out of the panel outlets and warmer air from the floor outlets. Floor Mode
Air comes from the floor outlets. A slight amount of air is directed through the defrost and side window
demister outlets. Mix Mode
Air comes from the floor, defrost and side window demist outlets. This mode works best in cold or snowy conditions. It allows you to stay comfortable
while keeping the windshield clear. Defrost Mode

NOTE: • If the system is in Mix, Bi-Level or Defrost Mode, the A/C can be turned off, but the A/C system shall remain active to prevent fogging of the windows. • If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed.
288 UNDERSTANDING YOUR INSTRUMENT PANEL Recirculation Control
When outside air contains smoke, odors, or high humidity, or if rapid cooling is desired, you may wish to recirculate interior air by pressing the RECIRCULATION control button. Recirculation mode should only be used temporarily. The recirculation LED will illuminate on the blower control knob when this button is selected. Push the button a second time to turn off the Recirculation mode LED and allow outside air into the vehicle. In cold weather, use of Recirculation mode may NOTE: lead to excessive window fogging. The Recirculation mode is not allowed in the Floor, Mix and Defrost modes to improve window clearing operation. Recirculation will be disabled automatically if these modes are selected.
Summer Operation The engine cooling system in air conditioned vehicles must be protected with a high-quality antifreeze coolant to provide proper corrosion protection and to protect against engine overheating. A solution of 50% ethylene glycol antifreeze coolant and 50% water is recommended. Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for proper coolant selection. Winter Operation To ensure the best possible heater and defroster perfor- mance, make sure the engine cooling system is function- ing properly and the proper amount, type, and concen- tration of coolant to “Maintenance Procedures” in “Maintaining Your Vehicle” for proper coolant selection. Use of the air Recirculation mode during Winter months is not recommended because it may cause window fogging.
is used. Refer
UNDERSTANDING YOUR INSTRUMENT PANEL 289
Outside Air Intake Make sure the air intake, located directly in front of the windshield, is free of obstructions such as leaves. Leaves collected in the air intake may reduce airflow, can cause odor, and if they enter the plenum they could plug the water drains. In Winter months make sure the air intake is clear of ice, slush and snow.
Vacation/Storage Any time you store your vehicle or keep it out of service (i.e., vacation) for two weeks or more, run the air conditioning system at idle for about five minutes in fresh air with the blower setting in high. This will ensure adequate system lubrication to minimize the possibility of compressor damage when the system is started again. Window Fogging and Frosting Vehicle windows tend to fog on the inside of the glass in mild, rainy and/or humid weather. Windows may frost on the inside of the glass in very cold weather. To clear the windows, select Defrost or Mix mode and increase the front blower speed. Do not use the Recirculation mode without A/C for long periods, as fogging may occur.

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.
WARNING!
• Accidents can be caused by inadvertently moving the shift lever or by pressing the accelerator pedal. This may cause excessive heat in the exhaust system, resulting in overheating and vehicle fire which may cause serious or fatal injuries. • Do not leave children or animals inside parked vehicles in hot weather. Interior heat buildup may cause serious injury or death.
STARTING AND OPERATING 297
Normal Starting Normal starting of either a warm or cold engine is obtained without pumping or pressing the accelerator pedal. Turn the key fob to the START position and release when the engine starts. If the engine fails to start within 10 seconds, turn the key fob to the OFF position, wait five seconds, then repeat the “Normal Starting” procedure. Automatic Transmission Start the engine with the shift lever in the NEUTRAL or PARK position. Apply the brake before shifting into any driving range. NOTE: This vehicle is equipped with a transmission shift interlocking system. The brake pedal must be pressed to shift out of PARK.
298 STARTING AND OPERATING Tip Start Feature Do not press the accelerator. Turn the ignition switch briefly to the START position and release it. The starter motor will continue to run but will automatically disen- gage when the engine is running. 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.
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. • Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic transmission cannot be started this way. Unburned fuel could enter the catalytic converter and once the engine has started, ignite and damage the converter and vehicle. • If the vehicle has a discharged battery, booster cables may be used to obtain a start from a booster battery or the battery in another vehicle. This type of start can be dangerous if done improperly. Refer to “Jump Starting” in “What To Do In Emergen- cies” for further information.
STARTING AND OPERATING 299
If the engine has been flooded, it may start to run, but not have enough power to continue running when the key fob is released. If this occurs, continue cranking with the accelerator pedal pushed all the way to the floor. Release the accelerator pedal and the key fob 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. After Starting The idle speed is automatically controlled and will de- crease as the engine warms up.
1500 Models The engine block heater cord is routed under the hood on the passenger side of the vehicle near the right head lamp assembly. It is located between the front grill and the radiator, but underneath the black upper seal. 2500/3500 Models The engine block heater cord is routed through the grille by the right front tow hook. It includes a removable cap that is secured by a tethered strap. It also has a c-clip that is used for storage when not in use for the winter months. During winter months, remove the heater cord wiring assembly from itself on the c-clip.
ENGINE BLOCK HEATER — IF EQUIPPED The engine block heater warms the engine and permits quicker starts in cold weather. Connect the cord to a standard 110-115 Volt AC electrical outlet with a grounded, three-wire extension cord.

(Continued)
It is dangerous to move the shift lever out of PARK or NEUTRAL 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 reverse. 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.
Key Ignition Park Interlock This vehicle is equipped with a Key Ignition Park Inter- lock which requires the shift lever to be placed in PARK prior to turning the key fob to the LOCK position. The key fob can only be removed from the ignition switch when the ignition is in the LOCK position and once removed the shift lever is locked in PARK. Brake/Transmission Shift Interlock System This vehicle is equipped with a Brake Transmission Shift Interlock System (BTSI) that holds the shift lever in the PARK position when the ignition switch is in the LOCK position. To move the shift lever out of the PARK position, the ignition switch must be turned to any other switch position (ACC, ON, or START) (engine running or not) and the brake pedal must be pressed.

5. Move the shift lever into the NEUTRAL position. 6. The vehicle may then be started in NEUTRAL. 7. Reinstall the override cover.
304 STARTING AND OPERATING Never use PARK while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. Always apply the parking brake first, then place the shift lever in the PARK position.
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully when parked to guard against vehicle movement and possible injury or damage. • It is dangerous to move the shift lever out of PARK or NEUTRAL 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 reverse. 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.
REVERSE This range is for moving the vehicle rearward. Use this range only after the vehicle has come to a complete stop. NEUTRAL This range is used when the vehicle is standing for prolonged 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 for any other reason with shift lever in NEUTRAL can result in severe transmission damage. Refer to “Recreational Tow- ing” in “Starting and Operating” and “Towing a Disabled Vehicle” in “What To Do In Emergencies” for further information. DRIVE This range is for most city and highway driving.
2 (Second) This range is for moderate grades and to assist braking on dry pavement or in mud and snow. Begins at a stop in low gear with automatic upshift to second gear. Will not shift to third gear. 1 (First) This range is for hard pulling at low speeds in mud, sand, snow, or on steep grades. Begins and stays in low gear with no upshift. Provides engine compression braking at low speeds. Overdrive Operation The Overdrive automatic transmission contains an elec- tronically controlled fourth and fifth gear (OVERDRIVE).

If the vehicle is started in extremely cold tem- NOTE: peratures, the transmission may not shift into OVER- DRIVE 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. 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 “Transmission
306 STARTING AND OPERATING Temperature Warning Light” may illuminate and the transmission may downshift out of OVERDRIVE until the transmission cools down. After the transmission cools down, the transmission will resume normal operation. The transmission will downshift from OVERDRIVE to DRIVE if the accelerator pedal is fully pressed 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 switch. This will improve performance and reduce the potential for transmission overheating or failure due to excessive shifting. When operating in TOW/HAUL mode, the transmission will shift to third gear and fourth gear will be enabled under steady cruise conditions.
TOW/HAUL Switch
The “TOW/HAUL Indicator Light” will illuminate in the instrument 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 switch must be pressed each time the engine is started.
Transmission Limp Home Mode Transmission function is monitored for abnormal condi- tions. If a condition is detected that could result in transmission damage, the Transmission Limp Home Mode will be engaged. In this mode, the transmission will remain in the current gear until the vehicle is brought to a stop. To reset the transmission, use the following procedure: 1. Stop the vehicle. 2. Move the shift lever to the PARK position. 3. Turn OFF the engine and be sure to turn the key fob to the LOCK position. 4. Wait approximately 10 seconds, then restart the en- gine. 5. Move the shift lever to the desired gear range.
STARTING AND OPERATING 307
If the problem is no longer detected, the transmission will return to normal operation. If the problem persists, PARK, REVERSE, and NEUTRAL will continue to oper- ate. Only second gear will operate in the DRIVE position. Have the transmission checked at your authorized dealer as soon as possible. Torque Converter Clutch A feature designed to improve fuel economy has been added to the automatic transmission of this vehicle. A clutch within the torque converter engages automatically at calibrated speeds. This may result in a slightly differ- ent feeling or response during normal operation in high gear. When the vehicle speed drops or during accelera- tion, the clutch automatically and smoothly disengages.308 STARTING AND OPERATING Five–Speed Automatic Transmission – If Equipped The shift lever display located in the instrument panel cluster indicates the transmission gear range. The shift lever is mounted either on the right side of the steering column (if equipped) or on the floor console (if equipped). You must press the brake pedal to move the shift lever out of the PARK position. To drive, move the shift lever from PARK or NEUTRAL to the DRIVE position. Pull the shift lever toward you when shifting into REVERSE or PARK, or when shifting out of PARK. Electronic Range Select (ERS) Operation The Electronic Range Select (ERS) shift control allows you to limit the highest available gear when the shift lever is in the DRIVE position. Move the console shift lever left (-) or right (+), or toggle the switch on the column shift lever down (-) or up (+) to select the desired top gear. For example, if the driver shifts the transmission
into 3 (third gear), the transmission will never shift above third gear, but can shift down to 2 (second gear) or 1 (first gear), when needed.

through third gear are underdrive gears, and fourth gear is direct drive. ERS fifth gear (Overdrive) is the same as the normal fourth gear. When in the DRIVE position in first through fourth gear, the first tap down (-), will display the ERS designation for the current gear (the transmission will not downshift). For example, if you are in DRIVE and are in third (direct) gear, when you tap the shift lever/switch one time in the (-) direction, the display will show 4 (ERS 4 is direct gear). Another tap down (-) will shift the transmission down to ERS 3 (the added underdrive gear). When in the DRIVE position in fifth gear, the first tap down (-) will downshift the transmission and display 5 (ERS 5 is the same as normal fourth gear). Another tap down (-) will shift the transmission down to ERS 4 (direct gear).⬙ To exit ERS mode, press and hold the top of the switch (+) until “D” is once again highlighted in the instrument cluster display.Console Shift Lever
On vehicles equipped with 4.7L or 5.7L engines, use of ERS (or TOW/HAUL mode) also enables an additional underdrive gear which is not normally used during through-gear accelerations. This additional gear im- proves vehicle performance and cooling capability when towing a trailer on certain grades. In ERS mode, first

WARNING! (Continued)
• Your vehicle could move and injure you and others if it is not completely in PARK. Check by trying to move the shift lever back and forth without first pulling it toward you after you have set it in PARK. Make sure it is in PARK before leaving the vehicle. • It is dangerous to move the shift lever out of PARK or NEUTRAL 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 reverse. 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 foot is firmly on the brake pedal.
REVERSE This range is for moving the vehicle rearward. Use this range only after the vehicle has come to a complete stop.

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 (antifreeze) are warm [usually after 1 to 3 miles (1.6 to 4.8 km) of driving].

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 switch when the transmission is sufficiently warm will dem- onstrate that the transmission is able to shift into and out of Overdrive. • If the vehicle has not been driven in several days, the first few seconds of operation after shifting the trans- mission 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 con- verter will refill within five seconds of shifting from PARK into any other gear position.
FOUR-WHEEL DRIVE OPERATION — IF EQUIPPED Four-wheel drive trucks are equipped with either a manually shifted transfer case or an electronically shifted
transfer case. Refer to the operating instructions for your transfer case, located in this section for further informa- tion. Manually Shifted Transfer Case – If Equipped The transfer case provides four mode positions. • Two-wheel drive high range (2H) • Four-wheel drive high range (4H) • Neutral (N) • Four-wheel drive low range (4L) This transfer case is intended to be driven in the 2H position for normal street and highway conditions such as dry, hard surfaced roads. When additional traction is required, the 4H and 4L positions can be used to lock the front and rear drive- shafts 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 “Transfer Case Position Indicator Light” in the instrument cluster will alert the driver that the vehicle is in four-wheel drive and that the front and rear drive- shafts are locked together. This light will illuminate when the transfer case is shifted into either the 4H or 4L position. There is no light for the 2H or 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).
STARTING AND OPERATING 315
Proper operation of four-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 four-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.316 STARTING AND OPERATING
WARNING!
You or others could be injured if you leave the vehicle unattended with the transfer case in the NEUTRAL position without first fully engaging the parking brake. The transfer case NEUTRAL 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 - This range is for normal street and highway driving on dry hard surfaced roads.
4H Four-Wheel Drive High Range - This range locks the front and rear driveshafts together forcing the front and rear wheels to rotate at the same speed. Additional traction for loose, slippery road surfaces only. Neutral - This range disengages the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle. Refer to “Recreational Towing” in “Starting and Operating” for further information. 4L Four-Wheel Drive Low Range - This range locks the front and rear driveshafts together forcing 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/ disengage faster if you momentarily release the accelera- tor 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 the transmission into NEUTRAL. 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 NEUTRAL.
STARTING AND OPERATING 317
NOTE: • Pausing in transfer case 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 the transmission into NEUTRAL, hold foot on brake, and turn the engine OFF. Make shift to the desired mode. • Shifting into or out of 4L is possible with the vehicle completely stopped, however difficulty may occur 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 preferred 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). • Do not attempt to shift into or from 4L while the
transmission is in gear.
318 STARTING AND OPERATING Transfer Case Position Indicator Light The “Transfer Case Position Indicator Light” 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 (Four-Position Switch) – If Equipped This is an electronic shift transfer case and is operated by the 4WD Control Switch (Transfer Case Switch), which is located on the instrument panel.
Transfer Case Switch (Four-Position)
This electronically shifted transfer case provides four mode positions: • Two-wheel drive high range (2WD) • Four-wheel drive lock range (4WD LOCK) • Four-wheel drive low range (4WD LOW)
• Neutral (NEUTRAL) This electronically shifted transfer case is designed to be driven in the two-wheel drive position (2WD) for normal street and highway conditions on dry, hard surfaced roads. When additional traction is required, the transfer case 4WD LOCK and 4WD LOW positions can be used to lock the front and rear driveshafts together, forcing the front and rear wheels to rotate at the same speed. This is accomplished by rotating the 4WD Control Switch to the desired position. Refer to “Shifting Procedure” in this section for specific shifting instructions. The 4WD LOCK and 4WD LOW positions are designed for loose, slippery road surfaces only. Driving in the 4WD LOCK and 4WD LOW positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline compo- nents.

NOTE: The transfer case NEUTRAL position is selected by pressing the recessed button located on the lower left hand corner of the 4WD Control Switch. The transfer case NEUTRAL position is to be used for recreational towing only. Refer to “Recreational Towing” in “Starting and Operating” for further information. Transfer Case Position Indicator Lights The Transfer Case Position Indicator Lights (4WD and 4LOW) are located in the instrument cluster 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.320 STARTING AND OPERATING 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 seconds, and retry selection. To find the shift require- ments, refer to the ⬙Shifting Procedure⬙ for your transfer case, located in this section.
The “SVC 4WD Warning Light” monitors the electronic shift four-wheel drive system. If this light remains on after engine start up or illuminates during driving, it means that the four-wheel drive system is not function- ing properly and that service is required.
WARNING!
Always engage the parking brake when powering down the vehicle if the “SVC 4WD Warning 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, as this can cause damage to driveline components.
When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 2WD or 4WD LOCK 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 four-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 four-wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit.
STARTING AND OPERATING 321
WARNING!
You or others could be injured if you leave the vehicle unattended with the transfer case in the NEUTRAL position without first fully engaging the parking brake. The transfer case NEUTRAL 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 Rear Wheel Drive High Range - This range is for normal street and highway driving on dry, hard surfaced roads.
322 STARTING AND OPERATING 4WD LOCK Four-Wheel Drive Lock Range - This range locks the front and rear driveshafts together forcing the front and rear wheels to rotate at the same speed. This range provides additional traction for loose, slippery road surfaces only. 4WD LOW Four-Wheel Drive Low Range - This range provides low speed four-wheel drive. It locks the front and rear driveshafts together forcing the front and rear wheels to rotate at the same speed. This range provides additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h). Neutral - This range disengages both the front and rear driveshafts from the powertrain. To be used for flat towing behind another vehicle. Refer to “Recreational Towing” in “Starting and Operating” for further information.
Shifting Procedure NOTE: • If any of the requirements to select a new transfer case position have not been met, the transfer case will not shift. The position indicator light for the previous position will remain ON and the newly selected posi- tion 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 seconds and try the shift again. • If all the requirements to select a new transfer case position have been met, the current position indicator light will turn OFF, the selected position indicator light will flash until the transfer case completes the shift.
When the shift is complete, the position indicator light for the selected position will stop flashing and remain ON.
2WD⇔ 4WD LOCK Rotate the 4WD control switch to the desired position. Shifts between 2WD and 4WD LOCK can be done with the vehicle stopped or in motion. With the vehicle in motion, the transfer case will engage/disengage faster if you momentarily release the accelerator pedal after turn- ing the control switch. If the vehicle is stopped, the ignition switch must be in the ON position with the engine either running or off. This shift cannot be com- pleted if the ignition switch is in the ACC position. NOTE: The four-wheel drive system will not allow shifts between 2WD/4WD LOCK if the front and/or rear wheels are spinning (no traction). In this situation, the
STARTING AND OPERATING 323
selected position indicator light will flash and the origi- nal position indicator light will remain ON. At this time, reduce speed and stop spinning the wheels to complete the shift. 2WD or 4WD LOCK⇔ 4WD LOW NOTE: When shifting into or out of 4WD LOW 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. You can use either of the following procedures: Preferred Procedure 1. With the engine running, slow the vehicle to 2 to 3 mph (3 to 5 km/h). 2. Shift the transmission into NEUTRAL.324 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 the transmission back into gear. Alternate Procedure 1. Bring the vehicle to a complete stop. 2. With the ignition switch in the ON position and the engine either OFF or running, shift the transmission into NEUTRAL. 3. Rotate the transfer case control switch to the desired position. 4. After the desired position indicator light is ON (not flashing), shift the transmission back into gear.
NOTE: • If Steps 1 or 2 of either the Preferred or Alternate Procedure are not satisfied prior to attempting the shift, then the desired position indicator light will flash continuously while the original position indicator light is ON, until all requirements have been met. • The ignition switch must be in the ON position for a shift to take place and for the position indicator lights to be operable. If the ignition switch is not in the ON position, the shift will not take place and no position indicator lights will be on or flashing.

• Four-wheel drive low range (4WD LOW) • Neutral (NEUTRAL) This electronically shifted transfer case is designed to be driven in the two–wheel drive position (2WD) or four- wheel drive position (4WD AUTO) for normal street and highway conditions on 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. When additional traction is required, the transfer case 4WD LOCK and 4WD LOW positions can be used to lock

AXLE LOCKER SYSTEM (2500 MODELS ONLY) — IF EQUIPPED This vehicle is equipped with electronically locking front and rear differentials. These differentials, when engaged, mechanically lock together the axle shafts forcing the wheels to spin at an equal rate. This allows the vehicle to maintain its momentum and prevents it from becoming
STARTING AND OPERATING 331
stuck. The locking front and rear differentials should only be engaged during low-speed, extreme off-road situa- tions where one wheel is likely to not be in contact with the ground. It is not recommended to drive the vehicle with the differentials locked on pavement due to the reduced ability to turn and speed limitations.CAUTION!
• Do not lock the front or rear axle on hard surfaced roads. The ability to steer the vehicle is reduced and damage to the drivetrain may occur when the axles are locked on hard surfaced roads. • Do not try to lock the rear axle if the vehicle is stuck and the tires are spinning. You can damage drivetrain components. Lock the rear axle before attempting situations or navigating terrain, which could possibly cause the vehicle to become stuck.
332 STARTING AND OPERATING The locking axles are controlled by the axle locker switch. The switch has three positions, AXLE UNLOCK, REAR LOCK, and FRONT/REAR LOCK. Under normal driv- ing conditions, the switch should be left in the AXLE UNLOCK position. In the AXLE UNLOCK position, the front and rear axles are unlocked. In the REAR LOCK position, the rear axle is locked. In the FRONT/REAR LOCK position, the front and rear axles are locked. NOTE: Even when the axles are in the AXLE UNLOCK position, the limited slip differential in the rear axle still provides torque biasing capability for moderate low traction environments. During the command to lock the axle, the indicator light will flash until the axle is locked. After the lock command has been successfully executed, the light will remain on solid.
To lock the rear axle, place the vehicle in 4LO. Refer to “Four Wheel Drive Operation” in “Starting and Operat- ing” for further information. Move the axle locker switch position to REAR LOCK while traveling less than 3 mph (5 km/h). The RR indicator light will remain on when the rear axle is locked. NOTE: Left to right wheel speed difference may be necessary to allow the axle to fully lock. If the indicator light is flashing after placing the switch in the REAR LOCK or FRONT/REAR LOCK position, drive the ve- hicle in a turn or on loose gravel to expedite the locking action.
WARNING!
Do not use the locked axle position for normal driving. A locked front axle is intended for off-road driving only. Locking the front axle during on-road driving will reduce the steering ability. This could cause an accident and you may be seriously injured.
To lock the front axle; move the axle locker switch to FRONT/REAR LOCK while traveling less than 3 mph (5 km/h). The indicator light will be solid when the front axle is locked. NOTE: The rear axle must be locked before the front axle will lock. To unlock the front axle; move the axle locker switch to REAR LOCK. The FRONT/REAR LOCK indicator light will go out when the axle is unlocked.
STARTING AND OPERATING 333
NOTE: The axle lockers could be torque locked due to side to side loads on the axle. Driving slowly while turning the steering wheel from a left hand turn to a right hand turn or driving in REVERSE for a short distance may be required to release the torque lock and unlock the axles. To unlock the rear axle; move the axle locker switch to AXLE UNLOCK. The REAR LOCK indicator light will go out when the rear axle is unlocked.SAFE OFF-ROAD DRIVING — POWER WAGON ONLY
Off-Road Driving Tips and Vehicle Characteristics Your vehicle has excellent on and off-road capabilities. These off-road capabilities will allow you to explore those wilderness trails where few travel, providing a source of exciting and satisfying recreation. Before you venture out, you should contact your local governmental agency to determine the designated off-road vehicle
334 STARTING AND OPERATING (ORV) trails or recreation areas. You should always tread lightly and only use established roads, trails or ORV recreational areas. The National Forest Service, Bureau of Land Management or local Department of Natural Re- sources are a wealth of information and usually have maps with marked trails. Skid Plates And Underbody Protection Steel skid plates protect the major driveline components of the truck including the fuel tank, transfer case and steering damper. In addition, this vehicle is equipped with boxed cross members and fore/aft rails. This addi- tional protection allows the vehicle to be utilized in severe off-road situations that would be considered im- passable by a normal truck. Ramp Travel Index (RTI) The ramp travel index is the distance, in inches, that you can drive your vehicle with one wheel on a 20-degree ramp without lifting any other wheel off the ground. This
distance up the ramp divided by the wheelbase of the vehicle and multiplied by 1,000 is the RTI. This vehicle has an RTI of 655, which means you can articulate one front wheel 32 inches in the air while the other three wheels remain in contact with the ground. Water Fording Characteristics Water fording characteristic is the vehicle’s ability to cross a body of still water, where the powertrain and drivetrain are safe from water ingestion. This vehicle has high water fording characteristics with the ability to cross a pool of water, without stopping, 24 inches deep at a maximum speed of 10 mph (16 km/h) and a pool of water 30 inches deep at a maximum speed of 5 mph (8 km/h), both with an entrance ramp angle of 1.3
degrees.CAUTION!
The door sill height is 25 inches. Water may intrude into the interior of the vehicle at greater depths.
Simultaneous Brake And Throttle Operation Many off-road driving conditions require the simulta- neous use of the brake and throttle (two footed driving). When climbing rocks, logs, or other stepped objects, using light brake pressure with light throttle will keep the vehicle from jerking or lurching. This technique is also used when you need to stop and restart a vehicle on a steep incline. The Basics Of Off-Road Driving You will encounter many types of terrain driving off- road. You should be familiar with the terrain and area before proceeding. There are many types of surface conditions: hard packed dirt, gravel, rocks, grass, sand, mud, snow and ice. Every surface has a different effect on
STARTING AND OPERATING 335
your vehicle’s steering, handling and traction. Control- ling your vehicle is one of the keys to successful off-road driving, so always keep a firm grip on the steering wheel and maintain a good driving posture. Avoid sudden accelerations, turns or braking. In most cases there are no road signs, posted speed limits or signal lights. Therefore you will need to use your own good judgment on what is safe and what isn’t. When on a trail you should always be looking ahead for surface obstacles and changes in terrain. The key is to plan your future driving route while remembering what you are currently driving over.CAUTION!
Never park your vehicle over dry grass or other combustible materials. The heat from your vehicle exhaust system could cause a fire.
336 STARTING AND OPERATING
WARNING!
Always wear your seat belt and firmly tie down cargo. Unsecured cargo can become projectiles in an off-road situation.
When To Use Low Range When driving off-road, shift into 4L (Low Range) for additional traction or to improve handling and control on slippery or difficult terrain. Due to the lower gearing, low range will allow the engine to operate in a higher power range. This will allow you to idle over obstacles and down hills, with improved control and less effort. Also, use 4L (Low Range) in rain, ice, snow, mud, sand, to get heavy loads rolling, improve traction, or whenever 4H (High Range) traction will not do the job. Driving In Snow, Mud And Sand There is a drastic reduction in traction when driving in snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore you should accelerate slowly, leave greater stopping distances and avoid abrupt vehicle maneuvers. You want to keep a slow constant steady pace. The key is to maintain the vehicle’s momentum.
