Operating Tips
Fast Cooldown For a fast cooldown, turn the blower fan rotary knob to the extreme right position, turn the mode control to the panel fresh position, press the snowflake button to turn on the air conditioning, and drive with the windows open for the first few minutes. Once the hot air has been expelled, close the windows and press the recirculation pushbutton, on dual-zone control, or switch the mode from panel/fresh to panel/recirculate on single-zone control. When a comfortable condition has been reached, choose a mode position and adjust the temperature control slide and blower speed as necessary to maintain comfort. For high humidity conditions it may be neces- sary to remain in the Recirculation mode to maintain comfort.
Window Fogging Windows will fog on the inside when the humidity inside the vehicle is high. This often occurs in mild or cool temperatures when it’s rainy or humid. In most cases turning on the air conditioning (pressing the snowflake button) will clear the fog. Adjust the temperature control, air direction and blower speed to maintain comfort. As the temperature gets colder it may be necessary to direct air onto the windshield by using MIX Mode position on the control. Adjust the temperature control and blower speed to maintain comfort. Higher blower speeds will reduce fogging. Interior fogging on the windshield can be quickly removed by selecting the defrost mode. Regular cleaning of the inside of the windows with a non-filming cleaning solution (vinegar and water works very well) will help prevent contaminates (cigarette smoke, perfumes, etc.) from sticking to the windows. Contaminates increase the rate of window fogging.
Summer Operation Air conditioned vehicles must be protected with a high quality antifreeze coolant during summer to provide proper corrosion protection and to raise the boiling point of the coolant for protection against overheating. A 50 % concentration is recommended. For proper coolant type, refer to “Recommended Fluids and Genuine Parts” in Section 7. When using the air conditioner in extremely heavy traffic in hot weather, especially when towing a trailer, addi- tional engine cooling may be required. If this situation is encountered, operate the transmission in a lower gear to increase engine RPM, coolant flow and fan speed. When stopped in heavy traffic, it may be necessary to shift into NEUTRAL and depress the accelerator slightly for fast idle operation to increase coolant flow and fan speed.
UNDERSTANDING YOUR INSTRUMENT PANEL 245
NOTE: On models equipped with Diesel engines, the idle speed will automatically increase to 1000 rpm at elevated coolant temperatures to improve engine cooling. Your air conditioning system is also equipped with an automatic recirculation system. When the system senses a heavy load or high heat conditions, it may use partial Recirculation A/C mode to provide additional comfort. Winter Operation When operating the system during the Winter months, make sure the air intake, located directly in front of the windshield, is free of ice, slush, snow, or other obstructions.

STARTING PROCEDURES Before starting your vehicle, adjust your seat, adjust both inside and outside mirrors, and fasten your seat belts. 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!
Do not leave children or animals inside parked vehicles in hot weather. Interior heat buildup may cause serious injury or death.
Normal Starting Normal starting of either a warm or cold engine is obtained without pumping or depressing the accelerator pedal. Turn the key to the START position and release when the engine starts. If the engine fails to start within 10 seconds, turn the key to the OFF position, wait five seconds, then repeat the starting procedure.
Automatic Transmission Start the engine with the shift lever in the NEUTRAL or PARK position. Apply the brake before shifting to any driving range. NOTE: This vehicle is equipped with a transmission shift interlocking system. The brake pedal must be depressed to shift out of PARK.
Tip Start Feature Do not press the accelerator. Turn the ignition key briefly to START position, and release it. The starter motor will continue to run, but will automatically disengage 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.
(Continued)
STARTING AND OPERATING 253
WARNING! (Continued)
• 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 Section 6.
If the engine has been flooded, it may start to run, but not have enough power to continue running when the key is released. If this occurs, continue cranking with the accel- erator pedal pushed all the way to the floor. Release the accelerator pedal and the key once the engine is running smoothly. If the engine shows no sign of starting after two 15- second periods of cranking with the accelerator pedal held to the floor, the “Normal Starting” procedure should be repeated.
254 STARTING AND OPERATING
After Starting The idle speed is automatically controlled and will de- crease as the engine warms up.
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. The engine block heater cord is routed under the hood on the driver side of the vehicle. It has a removable cap that is located on the driver’s side of the Integrated Power Module.
WARNING!
Remember to disconnect the cord before driving. Damage to the 110-115 Volt electrical cord could cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
a complete stop.
Damage to the transmission may occur if the follow- ing precautions are not observed: • Shift into PARK only after the vehicle has come to • Shift into or out of REVERSE only after the vehicle has come to a complete stop and the engine is at idle speed. • Do not shift from REVERSE, PARK, or NEUTRAL into any forward gear when the engine is above idle speed. • Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
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.
Automatic Transmission with Overdrive The gear shift lever display located in the instrument panel cluster indicates the transmission gear range (the selector is illuminated for night driving). The shift lever is mounted on the right side of the steering column. You must depress the brake pedal to pull the shift lever out of PARK position (Brake Interlock System). To drive, move the shift lever from PARK or NEUTRAL to the desired
STARTING AND OPERATING 255
DRIVE position. Pull the shift lever toward you when shifting into REVERSE, SECOND, FIRST or PARK, or when shifting out of PARK. Gear Ranges DO NOT race the engine when shifting from PARK or NEUTRAL position into another gear range. PARK This gear position supplements the parking brake by locking the transmission. The engine can be started in this range. Never use PARK while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. Always apply parking brake first, then place the shift lever into the PARK position. On four-wheel drive vehicles be sure that the transfer case is in a drive position!
256 STARTING AND OPERATING
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply parking brake fully when parked to guard against vehicle move- ment and possible injury or damage. • 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.

WARNING! (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.
REVERSE Use this range only after the vehicle has come to a complete stop. NEUTRAL Shift into NEUTRAL 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.
DRIVE This position provides all forward gears, including 3rd gear direct and 4th or 5th gear overdrive (see Overdrive Operation). Use this range for most city and highway driving. SECOND Use this position for driving slowly in heavy city traffic or on mountain roads where more precise speed control is desirable. Use it also when climbing long grades, and for engine braking when descending moderately steep grades. To prevent excessive engine speed do not exceed 45 mph (72 km/h) in this range. FIRST Use this position for driving up very steep hills and for engine braking at low speeds 20 mph (32 km/h) or less when going downhill. To prevent excessive engine speed, do not exceed 25 mph (40 km/h) in this range.
STARTING AND OPERATING 257
NOTE: Use caution when operating a heavily loaded vehicle in SECOND or FIRST gear selections in high ambients as torque converter slip can impose significant additional heat load on the cooling system. Overdrive Operation The overdrive automatic transmission contains an elec- tronically controlled fourth and fifth (if equipped) speed (Overdrive). The transmission will automatically shift from DRIVE to Overdrive if the following conditions are present: • the shift lever is in DRIVE; • the engine coolant has reached normal operating tem- • vehicle speed is above approximately 30 mph • the “TOW HAUL O/D OFF” switch has not been

NOTE: • If the vehicle is started in extremely cold temperatures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for opera- tion at this temperature. Normal operation will re- sume when the transmission fluid temperature has risen to a suitable level. Refer to the “Note” under “Torque Converter Clutch” in this section. • If the transmission temperature gets extremely hot, the transmission will automatically select the most desir- able gear for operation at this temperature. If the transmission temperature becomes hot enough the “Transmission Temperature Warning Light” may illu- minate and the transmission may downshift out of
Overdrive until the transmission cools down. After cool down, the transmission will resume normal operation.
from Overdrive to The transmission will downshift DRIVE if the accelerator pedal is fully depressed at vehicle speeds above approximately 35 mph (56 km/h). When To Use “TOW HAUL” and “O/D OFF” Modes 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.

economy) and automatic closed-throttle downshifts to 3rd gear are performed (for improved braking) when driving conditions warrant. Pressing the “TOW HAUL O/D OFF” button a second time to select O/D OFF will disable 4th and 5th gear completely, which should elimi- nate any excessive transmission shifting. 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. 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
Tow Haul O/D Off Switch
This will improve performance and 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

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 [usu- ally 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 transmis- sion 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 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. Manually Shifted Transfer Case Operating Information/Precautions 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 instru- ment cluster will alert the driver that the vehicle is in four-wheel drive and that the front and rear driveshafts 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.
STARTING AND OPERATING 261
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 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.
262 STARTING AND OPERATING
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 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 this section. 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
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
STARTING AND OPERATING 263
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. 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.
264 STARTING AND OPERATING
• 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.
Electronically Shifted Transfer Case Operating Information/Precautions (Five Position Switch) — If Equipped This is an electronically shifted transfer case and is operated by the transfer case switch, which is located on the instrument panel.
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.
Transfer Case Switch (Five Position)
This electronically shifted transfer case provides five mode positions. • Two-wheel drive high range (2WD) • Four-wheel drive automatic range (4WD AUTO) • Four-wheel drive lock range (4WD LOCK) • Four-wheel drive low range (4WD LOW) • Neutral (N) 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 (dry hard surfaced roads). Driving the vehicle in 2WD will have greater fuel economy benefits, as the front axle is not engaged in 2WD.
STARTING AND OPERATING 265
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 4WD LOCK and 4WD LOW 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. Refer to “Shifting Procedure” for specific shift- ing instructions. The 4WD LOCK and 4WD LOW posi- tions are designed for loose, slippery road surfaces only.
266 STARTING AND OPERATING
Driving in the 4WD LOCK and 4WD LOW positions on dry hard surfaced roads may cause increased tire wear and damage to the driveline components.
NEUTRAL Button
NOTE: The transfer case NEUTRAL position is selected by depressing 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 this section for specific procedures on shifting into and out of NEUTRAL. Transfer Case Position Indicator Lights — Electronically Shifted Transfer Case Only The “Transfer Case Position Indicator Lights” are located on the instrument cluster and indicate the current and desired transfer case selection. When you select a differ- ent transfer case position, the “Transfer Case Position Indicator Lights” will do the following: If all shift conditions are met: 1. The current “Transfer Case Position Indicator Light” will turn OFF. 2. The selected “Transfer Case Position Indicator Light” will flash until the transfer case completes the shift.
3. When the shift is completed, the “Transfer Case Posi- tion Indicator Light” for the selected position will stop flashing and remain ON. If one or more shift conditions are not met: 1. The “Transfer Case Position Indicator Light” for the current position will remain ON. 2. The newly selected “Transfer Case Position Indicator Light” will continue to flash. 3. The transfer case will not shift. NOTE: Before retrying a selection, make sure that all of 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 of the Owner’s Manual.
STARTING AND OPERATING 267
The “Service 4WD Warning Light” monitors the electric 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 ⴖService 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. This could cause damage to driveline components.
268 STARTING AND OPERATING
When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 2WD, 4WD AUTO 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.
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.
4WD AUTO Four-Wheel Drive Automatic Range - This range auto- matically engages when the vehicle senses a loss of traction. Additional traction for varying road conditions. 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. Additional traction for loose, slippery road surfaces only. 4WD LOW Four-Wheel Drive Low Range - Locks the front and rear driveshafts together forcing the front and rear wheels to rotate at the same speed. Additional traction and maxi- mum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h).

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 this section. Shifting Procedure — Electronically Shifted Transfer Case NOTE: • If any of the requirements to select a new transfer case position have not been met, the transfer case will not shift. The “Transfer Case Position Indicator Light” for the previous position will remain ON and the newly selected “Transfer Case 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 seconds and try the shift again.
270 STARTING AND OPERATING
• If all the requirements to select a new transfer case position have been met, the current “Transfer Case Position Indicator Light” will turn OFF, the selected “Transfer Case Position Indicator Light” will flash until the transfer case completes the shift. When the shift is completed, “Transfer Case Position Indicator Light” for the selected position will stop flashing and remain ON.
2WD ⇔ 4WD AUTO or 4WD LOCK Rotate the transfer case switch to the desired position. Shifts between 2WD and 4WD AUTO 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 accelera- tor pedal after turning the switch. If the vehicle is stopped, the ignition key must be in the ON position, with the engine either RUNNING or OFF. This shift cannot be completed if the key is in the accessory (ACC) position.
2WD or 4WD AUTO 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. 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. 3. While still rolling, rotate the transfer case switch to the desired position. 4. After the desired “Transfer Case Position Indicator Light” is ON (not flashing), shift the transmission back into gear.
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. 3. Rotate the transfer case control switch to the desired position. 4. After the desired “Transfer Case Position Indicator Light” is ON (not flashing), shift the transmission back into gear.
STARTING AND OPERATING 271
NOTE: • If steps 1 or 2 of either the Preferred or Alternate 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 “Transfer Case Position Indicator Light” will flash continuously while the original “Transfer Case Position Indicator Light” is ON, until all requirements have been met. • The ignition key must be ON for a shift to take place and for the “Transfer Case Position Indicator Lights” to be operable. If the key is not ON, then the shift will not take place and no “Transfer Case Position Indica- tor Lights” will be on or flashing. • If your are leaving your vehicle stored for longer than
21 days, refer to the section on “Vehicle Storage.”

• If all the requirements to select a new transfer case position have been met, the current “Transfer Case Position Indicator Light” will turn OFF, the selected “Transfer Case Position Indicator Light” will flash until the transfer case completes the shift. When the shift is completed, the “Transfer Case Position Indica- tor Light” for the selected position will stop flashing and remain ON.
2WD⇔ 4WD LOCK Rotate the transfer case 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 switch. If the vehicle is stopped, the ignition key must be in the ON position with the engine either running or off. This shift cannot be completed if the key is in the ACC position.
STARTING AND OPERATING 277
NOTE: The transfer case will not allow shifts between 2WD and 4WD LOCK if the front and/or rear wheels are spinning (no traction). In this situation, the selected “Transfer Case Position Indicator Light” will flash and the original “Transfer Case 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. USE EITHER OF THE FOLLOWING PROCEDURES: Preferred Procedure 1. With engine running, slow the vehicle to 2 to 3 mph (3
to 5 km/h).278 STARTING AND OPERATING
2. Shift the transmission into NEUTRAL. 3. While still rolling, rotate the transfer case switch to the desired position. 4. After the desired “Transfer Case Position Indicator Light” is ON (not flashing), shift the transmission back into gear. 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. 3. Rotate the transfer case switch into the desired posi- tion. 4. After the desired “Transfer Case 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, the desired “Transfer Case Position Indicator Light” will flash continuously while the original “Transfer Case Position Indicator Light” is ON, until all requirements have been met. • The ignition key must be ON for a shift to take place and for the “Transfer Case Position Indicator Lights” to be operable. If the key is not ON then the shift will not take place and no “Transfer Case Position Indica- tor Lights” will be on or flashing. • If your are leaving your vehicle stored for longer than
21 days, refer to the section on “Vehicle Storage.”
AXLE LOCKER SYSTEM — POWER WAGON ONLY 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 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.
STARTING AND OPERATING 279
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.
280 STARTING AND OPERATING
The locking axles are controlled by the axle locker switch located on the center console.
Locking Axle 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 this section of the manual. 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.
STARTING AND OPERATING 281
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. 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.

STABILIZER/SWAY BAR SYSTEM — POWER WAGON ONLY Your vehicle is equipped with an electronic disconnecting stabilizer/sway bar. This system allows greater front suspension travel in off-road situations. Due to the use of taller springs, this vehicle has an increased ride height of approximately 1.9 in (48.3 mm) in the front and 1.5 in (38.1 mm) in the rear. A major advantage to increasing ride height is the positive effect it has on approach/departure and break over angles. This system is controlled by the electronic control sway bar switch located on the instrument panel.
1 — On Road 2 — Off Road The switch has two positions; On-Road and Off-Road. The system is normally in the On-Road mode, indicated by a solid green light. The stabilizer/sway bar should remain in the On-Road mode during normal driving conditions.
WARNING!
Do not disconnect the stabilizer bar and drive on hard surfaced roads or at speeds above 18 mph (29 km/h), you may lose control of the vehicle, which could result in serious injury. The front stabilizer bar enhances vehicle stability and is necessary for main- taining control of the vehicle. The system monitors vehicle speed and will attempt to reconnect the stabilizer bar at speeds over 18 mph (29 km/h). This is indicated by a flashing off road light and solid on road light. Once vehicle speed is reduced below 14 mph (22 km/h), the system will attempt to return to the Off-Road mode.
To disconnect the stabilizer/sway bar, shift to either 4HI or 4LO as shown in “Four Wheel Drive Operation” and press the top of the stabilizer/sway bar button to obtain

the Off-Road position. The amber indicator light will flash until the stabilizer/sway bar has been fully discon- nected. NOTE: The stabilizer/sway bar may be torque locked due to left and right suspension height differences. This condition is due to driving surface differences or vehicle loading. to disconnect/reconnect, the right and left halves of the bar must be aligned. This alignment may require that the vehicle be driven onto level ground or rocked from side to side. To return to the On-Road mode; press the bottom of the stabilizer/sway bar button.

WARNING!
If the stabilizer/sway bar will not return to On-Road mode, vehicle stability is greatly reduced. Do not attempt to drive the vehicle over 18 mph (29 km/h). Driving faster than 18 mph (29 km/h) may cause loss of control of the vehicle, which could result in serious injury. Contact your local service center for assistance.
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 (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.
STARTING AND OPERATING 285
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.
High Mobility Characteristics This vehicle has high off-road mobility characteristics with an approach angle A= 35 degrees, a break-over angle B= 25.5 degrees, a running ground clearance C= 14.5 inches, a departure angle D= 26.5 degrees, an axle to ground clearance E= 8.4 inches front/E= 8.25 rear and has a ramp travel index (with the smart bar in off-road mode) of 655. Also, it has a grade-ability of a 60% (31
degree) slope.286 STARTING AND OPERATING

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,
Front and Rear (Shown) Differential Height E
288 STARTING AND OPERATING
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 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.
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. • Snow – In heavy snow or for additional control and traction at slower speeds, shift the transmission to a low gear and shift the transfer case to 4L (Low Range) if necessary. Do not shift to a lower gear than neces- sary to maintain headway. Over-revving the engine
STARTING AND OPERATING 289
can spin the wheels and traction will be lost. If you start to slow to a stop, try turning your steering wheel no more than a 1⁄4 turn quickly back and forth, while still applying throttle. This will allow the tires to get a fresh ⬙bite⬙ and help maintain your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high engine RPMs or vehicle speeds because engine brak- ing may cause skidding and loss of control. • Mud – Deep mud creates a great deal of suction around the tires and is very difficult to get through. You should use 4L (Low Range) with a gear low enough to maintain your momentum without shifting. If you start to slow to a stop, try turning your steering wheel no more than a 1⁄4 turn quickly back and forth for additional traction. Mud holes pose an increased threat of vehicle damage and getting stuck. They are
290 STARTING AND OPERATING
normally full of debris from previous vehicles getting stuck. As a good practice before entering any mud hole, get out and determine how deep it is, if there are any hidden obstacles and if the vehicle can be safely recovered if stuck. • Sand – Soft sand is very difficult to travel through with full tire pressure. When crossing soft sandy spots in a trail maintain your vehicle’s momentum and do not stop. The key to driving in soft sand using the appropriate tire pressure, accelerating slowly, avoid- ing abrupt maneuvers and maintaining the vehicle’s momentum. If you are going to be driving on large soft sandy areas or dunes, reduce your tire pressure to a minimum of 15 psi (103 kPa) to allow for a greater tire surface area. Reduced tire pressure will drastically improve your traction and handling, while driving on the soft sand, but you must return the tires to normal
air pressure before driving on pavement or other hard surfaces. Be sure you have a way to air the tires back up prior to reducing the pressure.
CAUTION!
Reduced tire pressures may cause tire unseating and total loss of air pressure. To reduce the risk of tire unseating, while at a reduced tire pressure, reduce your speed and avoid sharp turns or abrupt maneu- vers.
Crossing Obstacles (Rocks And Other High Points) While driving off road, you will encounter many types of terrain. These varying types of terrain bring different types of obstacles. Before proceeding review the path ahead to determine the correct approach and your ability to safely recover the vehicle if something goes wrong. Keeping a firm grip on the steering wheel, bring the
vehicle to a complete stop and then inch the vehicle forward until it makes contact with the object. Apply the throttle lightly while holding a light brake pressure and ease the vehicle up and over the object.
WARNING!
Crossing obstacles can cause abrupt steering system loading which could cause you to loose control of your vehicle.
Using a Spotter There are many times where it is hard to see the obstacle or determine the correct path. Determining the correct path can be extremely difficult when you are confronting many obstacles. In these cases have someone guide you over, through, or around the obstacle. Have the person stand a safe distance in front of you where they can see the obstacle, watch your tires and undercarriage, and guide you through.
STARTING AND OPERATING 291
Crossing Large Rocks When approaching large rocks, choose a path which ensures you drive over the largest with your tires. This will lift your undercarriage over the obstacle. The tread of the tire is tougher and thicker than the side wall and is designed to take the abuse. Always look ahead and make every effort to cross the large rocks with your tires.
CAUTION!
• Never attempt to straddle a rock that is large • Never attempt to drive over a rock which is large
enough to strike your axles or undercarriage.

Crossing a Ravine, Gully, Ditch, Washout or Rut When crossing a ravine, gully, ditch, washout or a large rut, the angled approach is the key to maintaining your vehicle’s mobility. Approach these obstacles at a 45- degree angle and let each tire go through the obstacle
292 STARTING AND OPERATING
independently. You need to use caution when crossing large obstacles with steep sides. Do not attempt to cross any large obstacle with steep sides at an angle great enough to put the vehicle at risk of a rollover. If you get caught in a rut, dig a small trench to the right or left at a 45-degree angle ahead of the front tires. Use the removed dirt to fill the rut ahead of the turnout you just created. You should now be able to drive out following the trench you just created at a 45-degree angle.
WARNING!
There is an increased risk of rollover when crossing an obstacle, at any angle, with steep sides.
Crossing Logs To cross a log, approach it at a slight angle (approxi- mately 10 to 15 degrees). This allows one front tire to be on top of the log while the other just starts to climb the log. While climbing the log, modulate your brake and
accelerator to avoid spinning the log out from under your tires. Then ease the vehicle off the log using your brakes.
CAUTION!
Do not attempt to cross a log with a greater diameter than the running ground clearance or the vehicle will become high centered.
Getting High Centered If you get hung up or high centered on an object, get out of the vehicle and try to determine what the vehicle is hung up on, where it is contacting the underbody and what is the best direction to recover the vehicle. Depend- ing on what you are in contact with, jack the vehicle up and place a few rocks under the tires so the weight is off
