CLIMATE CONTROLS

Manual Heating and Air Conditioning System — If Equipped The controls for the heating and air conditioning system in this vehicle consist of a series of rotary knobs. These comfort controls can be set to obtain desired interior conditions.

Manual Heating And Air Conditioning Controls

224 UNDERSTANDING YOUR INSTRUMENT PANEL The instrument panel features four dual-vane airflow registers. Two registers are located on the outer ends of the instrument panel and two are located in the center of the instrument panel. These registers can be closed to partially block airflow, and they can be adjusted to direct airflow where the occupant desires. Blower Control

The blower control rotary knob (on the left) controls the blower and can be set in one of four speeds and OFF. The blower fan motor will remain on un- til the system is turned to the OFF position or the ignition is turned OFF.

NOTE: For vehicles equipped with Remote Start, the climate controls will not function during Remote Start operation if the blower control is left in the “O” (Off) position.

Temperature Control

The temperature control rotary knob (in the center) controls the air tem- perature. The coldest temperature set- ting is on the extreme left and the warmest setting on the extreme right of the rotation. The knob can be posi- tioned at any point on the dial.

Mode Control

The mode control rotary knob (on the right) can be placed in several posi- tions. Dots between each of the mode selections identify intermediate modes that allow the occupants to fine tune airflow distribution.

Defrost

Air is directed to the windshield through the outlets at the base of the windshield. Air is also

directed to the front door windows through the side window demister grilles. Some airflow is delivered to the floor while in defrost so that comfort can be maintained. Defrost/Floor

Air flows through the front and rear floor outlets and the outlets at the base of the windshield. Air is also directed to the front door windows through the side window demister grilles. Some airflow is delivered to the floor while in defrost so that comfort can be maintained. Floor

Air flows through the floor outlets located under the instrument panel and into the rear seating area through vents under the front seats. Some airflow is delivered to defrost while in the floor mode so that comfort can be maintained.

UNDERSTANDING YOUR INSTRUMENT PANEL 225

Bi-Level

Air flows both through the outlets located in the instrument panel and those located on the floor. Air flows through the registers in the back of the center console, and under the front seats to the rear seat passengers. These registers can be closed to partially block airflow. The center console outlets deliver condi- tioned air while the floor outlets deliver heated air. Panel

Air flows through the outlets located in the instru- ment panel. Air flows through the registers in the back of the center console to the rear seat passengers. These registers can be closed to block airflow.

226 UNDERSTANDING YOUR INSTRUMENT PANEL Recirculation

The recirculation feature can be selected with the mode control knob. You may choose be- tween Bi-Level Recirculation and Panel Recir- culation air outlets while in this mode. Nor- mally, air enters from outside the vehicle. However, when in Recirculation mode air inside the vehicle is re-used. Use this mode to rapidly cool the inside of the vehicle. The Recirculation mode can also be used to temporarily block out outside odors, smoke, and dust. Air Conditioning

To turn on the Air Conditioning, set the fan control at any speed and press the snowflake button located on the control panel. Conditioned air will be directed through the outlets selected by the mode control. A light in the snowflake button shows that the air conditioning is on.

Slight changes in engine speed or power may be noticed when the air conditioning compressor is on. This is a normal occurrence as the compressor will cycle on and off to maintain comfort and increase fuel economy. Automatic Temperature Control (ATC) — If Equipped The Automatic Temperature Control (ATC) system auto- matically maintains the interior comfort level desired by the driver and passenger.

UNDERSTANDING YOUR INSTRUMENT PANEL 227
Turn the mode control (on the right) knob to AUTO, and place the blower control (on the left) to either LO AUTO or HI AUTO. The LO AUTO position should be used for front seat occupants only. The HI AUTO position should be used when more airflow is desired, or when rear seat occupants are present. Dial in the comfort setting you would like the system to maintain by rotating the driver’s or passenger’s control knob. Once the comfort level is selected, the system will maintain that level automati- cally using the heating system. Should the desired com- fort level require air conditioning, the system will auto- matically make the adjustment.

Automatic Temperature Controls (ATC)

NOTE: The numbers on the temperature dial represent a comfort setting when the Mode knob is set to AUTO, and not the actual air temperature.

228 UNDERSTANDING YOUR INSTRUMENT PANEL NOTE: The temperature setting can be adjusted at any time without affecting automatic control operation. How- ever, if the driver and/or passenger temperature knobs are set to the full hot or full cold positions, the air temperature out of the ducts will be full hot or full cold respectively. With the temperature setting in these posi- tions, the system does not attempt automatic comfort control. Air Conditioning

The air conditioning in this system is automatic. Pressing this button while in AUTO mode will cause the LED to flash three times and remain off. This indicates that the system is in AUTO and requesting the air conditioning is not necessary.

Recirculation

The system will automatically control recircu- lation. However, pressing this button will tem- porarily put the system in Recirculation mode. This can be used when outside conditions such as smoke, odors, dust, or high humidity are present. This will cause the LED to illuminate. NOTE: • The surface of the climate control panel, and the top center of the instrument panel should be kept free of debris due to the climate control sensor’s location. Mud on the windshield may also cause poor operation of this system.

• To provide you with maximum comfort in the auto- matic mode, during cold start-ups the blower fan will remain off until the engine warms up. However, the fan will engage immediately if the defrost mode is selected or if you manually select a blower speed. • Under certain conditions (after the vehicle is turned off) the climate control system may recalibrate and a noise may be heard for 20 seconds. This is part of normal operation. • Most of the time, when in Automatic operation, you can temporarily put the system into Recirculation mode by pressing the Recirculation button. However, under certain conditions in automatic the system is blowing air out of the defrost vents. When these conditions are present, and the Recirculation button is pressed, the indicator will flash and remain off. This tells you that you are unable to go into Recirculation

UNDERSTANDING YOUR INSTRUMENT PANEL 229
mode at this time. If you would like to go to Recircu- lation mode, you must first move your mode knob to Panel, Panel/Floor, or Floor, then press the Recircula- tion button. This feature will reduce the possibility of window fogging. Manual Operation This system offers a full complement of manual override features which consist of Blower Preferred Automatic, Mode Preferred Automatic with Manual Air Temperature Control, and Manual. This means the customer can override the blower, mode, and disable Automatic Tem- perature Control completely. NOTE: Please read the Automatic Temperature Control Operation Chart below for details.

230 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE: Regardless of the type of operation, when a temperature knob is set to the full clockwise or full counterclockwise position, the system will deliver full hot or full cold air out of the ducts, respectively. The operator can override the AUTO mode setting and select the direction of the air by rotating the right mode knob to one of the following positions. When the Mode is set to any position other than AUTO, the automatic control of air temperature is disabled. The user must adjust the temperature knobs to obtain the desired tem- perature. Defrost

Air is directed to the windshield through the outlets at the base of the windshield. Air is also directed to the front door windows through the side window demister grilles. Some airflow is delivered to the floor while in defrost so that comfort can be maintained.

UNDERSTANDING YOUR INSTRUMENT PANEL 231
NOTE: The defrost mode is not automatically selected. It must be manually selected, when desired. Defrost/Floor

Air flows through the front and rear floor outlets and the outlets at the base of the windshield. Air is also directed to the front door windows through the side window demister grilles. Some airflow is delivered to the floor while in defrost so that comfort can be maintained. Floor

Air flows through the floor outlets located under the instrument panel and into the rear seating area through vents under the front seats. Some airflow is delivered to defrost while in floor mode, so that comfort can be maintained.

232 UNDERSTANDING YOUR INSTRUMENT PANEL Bi-Level

Air flows both through the outlets located in the instrument panel and those located on the floor. Air flows through the registers in the back of the center console, and under the front seats to the rear seat passengers. These registers can be closed to block airflow. The center console outlets deliver conditioned air while the floor outlets deliver heated air. Panel

Air flows through the outlets located in the instru- ment panel. Air flows through the registers in the back of the center console to the rear seat passengers. These registers can be closed to block airflow. Air Conditioning

Press this button to turn on and off the air condi- tioning during manual operation only. Condi- tioned outside air is then directed through the

outlets selected on the mode control dial. The button includes an LED that illuminates when manual operation is selected. NOTE: To manually control the air conditioning, the mode selector must be moved out of the AUTO position. Recirculation

This button can be used to block out smoke, odors, dust, high humidity, or if rapid cooling is desired. The Recirculation mode should only be used temporarily. The button includes an LED that illuminates, which indicates that the Recircula- tion mode is active. You may use this feature separately. NOTE: Extended use of recirculation may cause the windows to fog. If the interior of the windows begins to fog, press the Recirculation button to return to outside air. Some temperature/humidity conditions will cause captured interior air to condense on windows and ham- per visibility. For this reason, the system will not allow

Recirculation mode to be selected while in the defrost or defrost/floor modes. Attempting to use Recirculation while in these modes will cause the LED in the button to blink and then turn off. Rear Climate Control — If Equipped The Manual Rear Climate Control system has one floor air outlet (passenger side), and two panel outlets in the rear quarter trim (on each side). The unit provides warm or cool air through the floor and upper outlets. If rear heating/cooling is desired, press the Rear On/Off Switch (located in the upper switch bank above the controls) and select Floor, Bi-Level, or Panel from the Rear Control Panel (right knob located on the right rear quarter trim panel).

UNDERSTANDING YOUR INSTRUMENT PANEL 233

Rear On/Off Switch

The rear temperature, blower speed, and mode control can be adjusted as desired by the third row seat occu- pants.

234 UNDERSTANDING YOUR INSTRUMENT PANEL

Rear Control Panel

NOTE: The rear climate control system cannot be con- trolled from the front seat; it can only be turned on and off. All control of the rear system must be performed by the rear occupants.

Rear Blower Control The left knob on the Rear Control Panel has four posi- tions, “Off”, and a range of three blower speeds. This allows the third row seat occupants to control the volume of air circulated in the rear of the vehicle.

CAUTION!

Interior air enters the Manual Rear Zone Climate Control system through an intake grille located in the passenger side trim panel behind the third seat. The heater outlets are located in the passenger side trim panel just behind the sliding door. Do not block or place objects directly in front of the inlet grille or heater outlets. The electrical system could overload causing damage to the blower motor.

Rear Temperature Control The center knob on the Rear Control Panel allows the third row seat occupants to have control of the rear temperature as follows: • When the temperature knob is in the cold (Blue) position, cold air will be delivered from the outlets. As the temperature knob is turned towards the hot (Red) position, the air will get warmer.

Rear Mode Control

Floor

Air flows through the floor outlet located on the right side of the rear floor into the rear seating area.

Bi-Level

Air flows through both the outlets located in the rear quarter trim panels, and the one located on the floor. The rear quarter trim panel outlets can be closed to block airflow.

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. 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.

236 UNDERSTANDING YOUR INSTRUMENT PANEL 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. Refer to Fluids, Lubri- cants, and Genuine Parts in Section 7 for the proper coolant type. When using the air conditioner in extremely heavy traffic, in hot weather, especially when towing a trailer, additional engine cooling may be required. If this situa- tion 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 press the accelerator slightly for fast idle operation to increase coolant flow and fan speed. 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, snow, or other obstructions. Vacation Storage Anytime you store your vehicle, or keep it out of service (i.e. vacation) for two weeks or more, run the air condi- tioning system at idle for about five minutes in the fresh air and high blower setting. This will ensure adequate system lubrication to minimize the possibility of com- pressor damage when the system is started again.

STARTING PROCEDURE Before starting your vehicle, adjust your seat, adjust the inside and outside mirrors, fasten your seat belt, and if present, instruct all other occupants to buckle their seat belts.

WARNING!

• Never leave children alone in a vehicle. Leaving unattended children in a vehicle is dangerous for a number of reasons. A child or others could be seriously or fatally injured. Do not leave the key in the ignition. A child could operate power win- dows, other controls, or move the vehicle. • Do not leave animals or children inside parked vehicles in hot weather; interior heat buildup may cause serious injury or death.

STARTING AND OPERATING 243

Normal Starting

Tip Start NOTE: Normal starting of either a cold or a warm engine is obtained without pumping or pressing the accelerator pedal. Do not press the accelerator. Use the Fob with Integrated Key to briefly turn the ignition switch to the START position and release it as soon as the starter engages. The starter motor will continue to run, and it will disengage automatically when the engine is running. If the engine fails to start, the starter will disengage automatically in 10 seconds. If this occurs, turn the ignition switch to the LOCK position, wait 10 to 15 seconds, then repeat the “Normal Starting” procedure.

244 STARTING AND OPERATING Extreme Cold Weather (Below ⫺20°F or ⫺29°C) To ensure reliable starting at these temperatures, use of an externally powered electric engine block heater (avail- able from your authorized dealer) is recommended. If Engine Fails To Start

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.

(Continued)

WARNING! (Continued)

• 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 dis- charged 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 dan- gerous if done improperly. Refer to Section 6 for proper jump-starting procedures and follow them carefully.

If the engine fails to start after you have followed the “Normal Starting” or “Extreme Cold Weather” proce- dures, it may be flooded. To clear any excess fuel, push the accelerator pedal all the way to the floor and hold it. Then, turn the ignition switch to the START position and

release it as soon as the starter engages. The starter motor will disengage automatically in 10 seconds. Once this occurs, release the accelerator pedal, turn the ignition switch to the LOCK position, wait 10 to 15 seconds, then repeat the “Normal Starting” procedure.

CAUTION!

To prevent damage to the starter, wait 10 to 15 sec- onds before trying again.

After Starting The idle speed is controlled automatically and it will decrease 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 heater cord to a ground-fault interrupter protected 110-115 Volt AC

STARTING AND OPERATING 245
electrical outlet with a grounded, three-wire extension cord. Use the heater when temperatures below 0°F (-18°C) are expected to last for several days. The block heater must be plugged in at least one hour to have an adequate warming effect on the coolant. The engine block heater cord is located: • 3.7L Engine — coiled and strapped to the engine oil • 5.7L Engine — bundled and fastened to the injector

harness.

WARNING!

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

246 STARTING AND OPERATING 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 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 rotating the key to the LOCK position. The key can only be removed from the ignition 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. Brake/Transmission Interlock Manual Override Your vehicle may be equipped with a shift lock manual override. The manual override may be used in the event that the shift lever should fail to move from PARK with the key in the ON position and the brake pedal pressed. To operate the shift lock manual override, perform the following steps:

STARTING AND OPERATING 247
1. Turn the key to the ON position without starting the engine. 2. Firmly set the parking brake. 3. Using a flat blade screwdriver, carefully remove the shift lock manual override cover, which is located on the PRNDL bezel. 4. Press and maintain firm pressure on the brake pedal. 5. Using the screwdriver, reach into the manual override opening. Press and hold the shift lock lever down.

248 STARTING AND OPERATING

Interlock Manual Override

6. Move the shift lever into the NEUTRAL position. 7. The vehicle may then be started in NEUTRAL. Have your vehicle inspected by your local authorized dealer, if the shift lock manual override has been used.

Five–Speed Automatic Transmission The electronically controlled transmission provides a precise shift schedule. The transmission electronics are self-calibrating; therefore, the first few shifts on a new vehicle, may be somewhat abrupt. This is a normal condition, and precision shifts will develop within a few hundred miles/kilometers. Gear Ranges

NOTE: After selecting any gear range, wait a moment to allow the selected gear to engage before accelerating. This is especially important when the engine is cold. If there is a need to restart the engine, be sure to cycle the key to the LOCK position before restarting. Transmission gear engagement may be delayed after restarting the engine if the key is not cycled to the LOCK position first. PARK This range 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 the parking brake first, then place the shift lever into the PARK position.

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. • 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.

STARTING AND OPERATING 249

REVERSE This range is for moving the vehicle backward. Use only after the vehicle has come to a complete stop. NEUTRAL This range is used when vehicle is standing for pro- longed periods with engine running. 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 the shift lever in NEUTRAL can result in severe transmission damage. Refer to “Recreational Towing” in Section 5 and “Towing a Disabled Vehicle” in Section 6 of this manual. DRIVE This range is used only when the vehicle is at a complete stop and the brakes are firmly applied. The transmission automatically upshifts through fifth gear. The DRIVE position provides optimum driving characteristics under all normal operating conditions.

250 STARTING AND OPERATING Electronic Range Select (ERS)Operation The Electronic Range Select (ERS) shift control allows you to move the shift lever left (-) or right (+) when the shift lever is in the DRIVE position, allowing you to limit the highest available gear. For example, if the driver shifts the transmission into ERS 3 (third gear), the trans- mission will never shift above third gear, but can shift down to 2 (second) or 1 (first), when needed. NOTE: • If you pull and hold (not tap) the shift lever to the left (-), the transmission will downshift to the lowest gear that can be attained without overrevving the engine. The display will show the gear the vehicle is in and will limit the top gear to the one displayed. • If you pull and hold (not tap) the shift lever to the right (+), the transmission will exit the gear limiting mode and shift to the appropriate gear. The display will read ⬙D⬙.

3.7L Engine When in the DRIVE position, the first tap to the left (-), will shift down one gear and will display that gear. For example, if you are in DRIVE and are in 5th gear, when you tap the shift lever one time to the left (-), the transmission will downshift to 4th gear and the display will show 4. Another tap to the left (-) will shift the transmission into 3rd gear. 5.7L Engine On vehicles equipped with 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 improves vehicle perfor- mance and cooling capability when towing a trailer on certain grades. ERS 1,2, and 3 are underdrive gears; ERS 4
is direct drive. ERS 5 (Overdrive) is the same as the normal 4th gear. When in the DRIVE position in 1st through 4th gear, the first tap to the left (-), will display the ERS designation for the current gear (the transmission will not

downshift). For example, if you are in DRIVE and are in 3rd (direct) gear, when you tap the shift lever one time to the left (-), the display will show 4 (ERS 4 is direct gear). Another tap to the left (-) will shift the transmission down to ERS 3 (the added underdrive gear). When in the DRIVE position in 5th gear, the first tap to the left (-) will downshift the transmission and display 5 (ERS 5 is the same as normal 4th gear). Another tap to the left (-) will shift the transmission down to ERS 4 (direct gear).

WARNING!

Do not downshift for additional engine braking on a slippery surface. The drive wheels could lose their grip and the vehicle could skid.

STARTING AND OPERATING 251
NOTE: To select the proper gear position for maximum deceleration (engine braking), move the shift lever to the left “D(-)” and hold it there. The transmission will shift to the range from which the vehicle can best be slowed down. Overdrive Operation The automatic transmission includes an electronically controlled Overdrive (5th gear for 3.7L engine, 4th and 5th gears for 5.7L engines). The transmission will auto- matically shift 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 switch has not been activated;

If the vehicle is started in extremely cold tem- NOTE: peratures, the transmission may not shift into Overdrive and will automatically select the most desirable gear for operation at this temperature. Normal operation will resume when the transmission fluid temperature has risen to a suitable level. Refer to the “Note” under “Torque Converter Clutch” later in this section. During cold temperature operation you may notice de- layed upshifts, depending on engine and transmission temperature. This feature improves the warmup time of the engine and transmission. 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

OVER TEMP” message may display, and the transmis- sion may downshift out of Overdrive until the transmis- sion cools down. After cool down, the transmission will resume normal operation. In high ambient temperatures with sustained high engine speed and load, an upshift, followed shortly thereafter by a downshift, may occur. The “TOW/HAUL Indicator Light” will turn off. This is a normal part of the overheat protection strategy when operating in the “TOW/ HAUL” mode. The transmission will downshift from Overdrive, to the most desirable gear, is fully pressed at vehicle speeds above approximately 35 mph (56 km/h). When To Use TOW/HAUL Mode — If Equipped 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

if the accelerator pedal

performance and reduce the potential for transmission overheating or failure due to excessive shifting. When operating in “TOW/HAUL” mode, the transmission will shift into direct gear and Overdrive will be enabled under steady cruise conditions.

TOW/HAUL Switch

STARTING AND OPERATING 253
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 (3.7L engine) or in direct gear (5.7L engine) 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 into the PARK position.

254 STARTING AND OPERATING 3. Turn the engine off, and be sure to turn the key to the LOCK position. 4. Wait approximately 10 seconds, then restart the en- gine. 5. Move the shift lever to the desired gear range. 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 2nd gear (3.7L engine) or 3rd gear (5.7L engine) will be available in the DRIVE position. Have the trans- mission checked at your authorized dealer as soon as possible. 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 a calibrated speed, at light throttle. It engages at

higher speeds under heavier acceleration. This may re- sult in a slightly different feeling or response during normal operation in high gear. When the vehicle speed drops below a calibrated speed, or during acceleration, the clutch automatically and smoothly disengages. The feature is operational in Overdrive and in DRIVE. NOTE: • The torque converter clutch will not engage until the transmission fluid and engine coolant are warm [usu- ally after 1 to 3 miles (1.6 to 4.8 km) of driving]. Because the engine speed is higher when the torque converter clutch is not engaged, it may seem as if the transmission is not shifting into Overdrive when cold. This is normal. Manually shifting (using the ERS shift control) between 4 (direct gear) and 5/D (Overdrive gear) positions will demonstrate that the transmission is able to shift into and out of Overdrive. For vehicles with 5.7L engines (which have two Overdrive gears),

the transmission may not shift into the top Overdrive gear (normal 5th gear) until the transmission fluid and engine coolant are warm. • 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.

Rocking The Vehicle If the vehicle becomes stuck in snow, sand, or mud, it can often be moved by a rocking motion. Move the shift lever between DRIVE and REVERSE, while applying slight pressure to the accelerator. NOTE: The Electronic Stability Program (ESP) and Traction Control (if equipped) should be turned OFF

STARTING AND OPERATING 255
before attempting to rock the vehicle. Refer to “Electronic Brake Control System” in Section 3 of this manual. The least amount of accelerator pedal pressure to main- tain the rocking motion, without spinning the wheels or racing the engine, is most effective. Racing the engine or spinning the wheels, due to the frustration of not freeing the vehicle, may lead to transmission overheating and failure. Allow the engine to idle with the shift lever in NEUTRAL for at least one minute after every five rocking-motion cycles. This will minimize overheating and reduce the risk of transmission failure during pro- longed efforts to free a stuck vehicle.

CAUTION!

When “rocking” a stuck vehicle by moving between “First” and REVERSE, do not spin the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.

256 STARTING AND OPERATING FOUR-WHEEL DRIVE OPERATION

Quadra-Trac I姞 Operating Instructions/ Precautions — If Equipped The Quadra-Trac I威 is a single-speed (HI range only) transfer case, which provides convenient full-time four– wheel drive. No driver interaction is required. The Brake Traction Control (BTC) System, which combines standard ABS and Traction Control, provides resistance to any wheel that is slipping to allow additional torque transfer to wheels with traction. NOTE: The Quadra-Trac I威 system is not appropriate for conditions where 4WD LOW range is recommended. Refer to “Off-Road Driving Tips” in this section. Quadra-Trac II姞 Operating Instructions/ Precautions — If Equipped The Quadra-Trac II威 transfer case is fully automatic in the normal driving 4WD HI mode. The Quadra-Trac II威 transfer case provides three mode positions:

• 4WD HI • NEUTRAL • 4WD LOW This transfer case is fully automatic in the 4WD HI mode. When additional traction is required, the 4WD LOW position can be used to lock the front and rear driveshafts together and force the front and rear wheels to rotate at the same speed. The 4WD LOW position is intended for loose, slippery road surfaces only. Driving in the 4WD LOW position on dry, hard-surfaced roads may cause increased tire wear and damage to driveline components. When operating your vehicle in 4WD LOW, the engine speed is approximately three times that of the 4WD HI position 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 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 N (Neutral) position without first fully engaging the parking brake. The transfer case N (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.

STARTING AND OPERATING 257

Shift Positions

For additional information on the appropriate use of each transfer case mode position, see the information below: 4WD HI This range is used on surfaces such as ice, snow, gravel, sand, and dry hard pavement. NEUTRAL This range disengages both the front and rear driveshafts from the powertrain. It is to be used for flat towing behind another vehicle. Refer to “Recreational Towing” in Section 5 of this manual. 4WD LOW This range is for low speed four-wheel drive. It locks the front and rear driveshafts together and forces the front and rear wheels to rotate at the same speed. It provides

258 STARTING AND OPERATING additional traction and maximum pulling power for loose, slippery road surfaces only. Do not exceed 25 mph (40 km/h). Shifting Procedures

4WD HI to 4WD LOW With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), key ON or engine running, shift the transmission into NEUTRAL, and raise the transfer case T-handle. The “4WD LOW” indicator light in the instrument cluster will begin to flash and remain on solid when the shift is complete. Release the T-handle. If shift conditions/interlocks are not met, or a NOTE: transfer case motor temperature protection condition exists, a “CHECK SHIFT PROCEDURES” message will flash from the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in Section 4 of this manual.

Shifter T-Handle

4WD LOW to 4WD HI With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), key ON or engine running, shift the transmission into NEUTRAL, and raise the transfer case T-handle. The

“4WD LOW” indicator light in the instrument cluster will flash and go out when the shift is complete. Release the T-handle. NOTE: • If shift conditions/interlocks are not met, or a transfer case motor temperature protection condition exists, a “CHECK SHIFT PROCEDURES” message will flash from the Electronic Vehicle Information Center (EVIC). to “Electronic Vehicle Information Center Refer (EVIC)” in Section 4 of this manual. • Shifting into or out of 4WD LOW is possible with the vehicle completely stopped; however, difficulty may occur due to the mating clutch teeth not being prop- erly aligned. Several attempts may be required for clutch teeth alignment and shift completion to occur. The preferred method is with the vehicle rolling 0 to

STARTING AND OPERATING 259
3 mph (0 to 5 km/h). If the vehicle is moving faster than 3 mph (5 km/h), the transfer case will not allow the shift.

NEUTRAL Shift Procedure 1. Key ON, engine off. 2. Vehicle stopped, with foot on brake. 3. Place the transmission into NEUTRAL. 4. Hold down the NEUTRAL “pin” switch (with a pen, etc.) for four seconds until the LED light by the switch starts to blink indicating shift in progress. The light will stop blinking (stay on solid) when the NEUTRAL shift is complete. A “4WD SYSTEM IN NEUTRAL” message will display on the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in Section 4 of this manual.

5. Repeat Steps 1 to 4 to shift out of NEUTRAL. If shift conditions/interlocks are not met, a NOTE: “CHECK SHIFT PROCEDURES” message will flash from the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in Section 4 of this manual.

Quadra-Drive姞 II System — If Equipped The optional Quadra-Drive威 II System features three torque transfer couplings. The couplings include Elec- tronic Limited-Slip Differential (ELSD) front and rear axles and Quadra-Trac II威 transfer case. The optional ELSD axles are fully automatic and require no driver input to operate. Under normal driving conditions, the units function as standard axles, balancing torque evenly between left and right wheels. With a traction difference between left and right wheels, the coupling will sense a speed difference. As one wheel begins to spin faster than the other, torque will automatically transfer from the wheel that has less traction, to the wheel that has traction. While the transfer case and axle couplings differ in design, their operation is similar. Follow the Quadra-Trac II威 transfer case shifting information, preceding this section, for shifting this system.

ON-ROAD DRIVING TIPS Utility vehicles have higher ground clearance and a narrower track to make them capable of performing in a wide variety of off-road applications. Specific design characteristics give them a higher center of gravity than ordinary cars. An advantage of the higher ground clearance is a better view of the road, allowing you to anticipate problems. They are not designed for cornering at the same speeds as conventional two-wheel drive vehicles any more than low-slung sports cars are designed to perform satisfacto- rily in off-road conditions. If at all possible, avoid sharp turns or abrupt maneuvers. As with other vehicles of this type, failure to operate this vehicle correctly may result in loss of control or vehicle rollover.

STARTING AND OPERATING 261

OFF-ROAD DRIVING TIPS

NOTE: Prior to off-road driving, remove the front air dam to prevent damage. The front air dam is attached to the lower front fascia with quarter turn fasteners and can be removed by hand. When to Use 4WD LOW Range — If Equipped When off-road driving, shift to 4WD LOW for additional traction. This range should be limited to extreme situa- tions such as deep snow, mud, or sand where additional low speed pulling power is needed. Vehicle speeds in excess of 25 mph (40 km/h) should be avoided when in 4WD LOW range. Driving Through Water Although your vehicle is capable of driving through water, there are a number of precautions that must be considered before entering the water.

262 STARTING AND OPERATING

CAUTION!

When driving through water, do not exceed 5 mph (8 km/h). Always check water depth before entering, as a precaution, and check all fluids afterward. Driv- ing through water may cause damage that may not be covered by the new vehicle limited warranty.

Driving through water more than a few inches/ centimeters deep will require extra caution to ensure safety and prevent damage to your vehicle. If you must drive through water, try to determine the depth and the bottom condition (and location of any obstacles) prior to entering. Proceed with caution and maintain a steady controlled speed less than 5 mph (8 km/h) in deep water to minimize wave effects. Flowing Water If the water is swift flowing and rising (as in storm run-off), avoid crossing until the water level recedes

and/or the flow rate is reduced. If you must cross flowing water avoid depths in excess of 9 in (23 cm). The flowing water can erode the streambed, causing your vehicle to sink into deeper water. Determine exit point(s) that are downstream of your entry point to allow for drifting. Standing Water Avoid driving in standing water deeper than 20 in (51 cm), and reduce speed appropriately to minimize wave effects. Maximum speed in 20 in (51 cm) of water is less than 5 mph (8 km/h). Maintenance After driving through deep water, inspect your vehicle fluids and lubricants (engine oil, transmission oil, axle, transfer case) to assure the fluids have not been contami- nated. Contaminated fluid (milky, foamy in appearance) should be flushed/changed as soon as possible to pre- vent component damage.

Driving in Snow, Mud and Sand In heavy snow, when pulling a load, or for additional control at slower speeds, shift the transmission to a low gear and shift the transfer case to 4WD LOW if necessary. Refer to “Four-Wheel Drive Operation” in this section. Do not shift to a lower gear than necessary to maintain forward motion. Over-revving the engine can spin the wheels and traction will be lost. Avoid abrupt downshifts on icy or slippery roads, be- cause engine braking may cause skidding and loss of control. Hill Climbing

NOTE: Before attempting to climb a hill, determine the conditions at the crest and/or on the other side. Before climbing a steep hill, shift the transmission to a lower gear and shift the transfer case to 4WD LOW. Use first gear and 4WD LOW for very steep hills.

STARTING AND OPERATING 263
If you stall or begin to lose forward motion while climbing a steep hill, allow your vehicle to come to a stop and immediately apply the brakes. Restart the engine, and shift into REVERSE. Back slowly down the hill, allowing the compression braking of the engine to help regulate your speed. If the brakes are required to control vehicle speed, apply them lightly and avoid locking or skidding the tires.

WARNING!

If the engine stalls, you lose forward motion, or cannot make it to the top of a steep hill or grade, never attempt to turn around. To do so may result in tipping and rolling the vehicle. Always back care- fully straight down a hill in REVERSE gear. Never back down a hill in NEUTRAL using only the brake.

Remember, never drive diagonally across a hill always drive straight up or down.

264 STARTING AND OPERATING If the wheels start to slip as you approach the crest of a hill, ease off the accelerator and maintain forward motion by turning the front wheels slowly. This may provide a fresh “bite” into the surface and will usually provide traction to complete the climb. Traction Downhill Shift the transmission into a low gear, and the transfer case into 4WD LOW range. Let the vehicle go slowly down the hill with all four wheels turning against engine compression drag. This will permit you to control the vehicle speed and direction. When descending mountains or hills, repeated braking can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmis- sion whenever possible. After Driving Off-Road Off-road operation puts more stress on your vehicle than does most on-road driving. After going off-road, it is

always a good idea to check for damage. That way you can get any problems taken care of right away and have your vehicle ready when you need it. • Completely inspect the underbody of your vehicle. Check the tires, body structure, steering, suspension, and exhaust system for damage. • Check threaded fasteners for looseness, particularly on the chassis, drivetrain components, steering, and sus- pension. Retighten them, if required, and torque to the values specified in the Service Manual. • Check for accumulations of plants or brush. These things could be a fire hazard. They might hide damage to fuel lines, brake hoses, axle pinion seals, and propeller shafts.

• After extended operation in mud, sand, water, or similar dirty conditions, have brake rotors, wheels, brake linings, and axle yokes inspected and cleaned as soon as possible.

WARNING!

Abrasive material in any part of the brakes may cause excessive wear or unpredictable braking. You might not have full braking power when you need it to prevent an accident. If you have been operating your vehicle in dirty conditions, get your brakes checked and cleaned as necessary. • If you experience unusual vibration after driving in mud, slush or similar conditions, check the wheels for impacted material. Impacted material can cause a wheel imbalance and freeing the wheels of it will correct the situation.

STARTING AND OPERATING 265

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

266 STARTING AND OPERATING

WARNING!

CAUTION!

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

Do not use chemical flushes in your power steering system as the chemicals can damage your power steering components. Such damage is not covered by the New Vehicle Limited Warranty.

CAUTION!

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

Power Steering Fluid Check The power steering system requires the use of MOPAR威 Hydraulic System Power Steering Fluid or equivalent, which meets Chrysler Material Standard MS-10838.

WARNING!

Do not use Automatic Transmission Fluid (ATF), or other types of power steering fluids, when servicing the power steering system of this vehicle. Damage to the power steering system can result from the use of the wrong power steering fluid.

Checking the power steering fluid level at a defined service interval is not required. The fluid should only be checked if a leak is suspected, abnormal noises are

apparent, and/or the system is not functioning as antici- pated. Coordinate inspection efforts through an autho- rized dealer.

WARNING!

Fluid level should be checked on a level surface and with the engine off to prevent injury from moving parts and to ensure accurate fluid level reading. Do not overfill. Use only manufacturers recommended power steering fluid.

If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces.

STARTING AND OPERATING 267

PARKING BRAKE To set the parking brake, pull the lever up as firmly as possible. When the parking brake is applied with the ignition ON, the “Brake Warning Light” in the instru- ment cluster will illuminate. To release the parking brake, pull up slightly, press the center button, then lower the lever completely. NOTE: The “Brake Warning Light” indicates only that the parking brake is applied. It does not indicate the degree of brake application.

268 STARTING AND OPERATING

Parking Brake

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

WARNING!

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

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

ANTI-LOCK BRAKE SYSTEM The Anti-Lock Brake System (ABS) is designed to aid the driver in maintaining vehicle control under adverse braking conditions. The system operates with a separate computer to modulate hydraulic pressure, to prevent wheel lock-up and help avoid skidding on slippery surfaces. All vehicle wheels and tires must be the same size and type, and tires must be properly inflated, to produce accurate signals for the computer.

STARTING AND OPERATING 269

WARNING!

Significant over or under-inflation of tires or mixing sizes of tires or wheels on the vehicle can lead to loss of braking effectiveness.

The ABS conducts a low-speed self-test at about 12 mph (20 km/h). If you have your foot lightly on the brake while this test is occurring, you may feel slight pedal movement. The movement can be more apparent on ice and snow. This is normal. The ABS pump motor runs during the self-test at 12 mph (20 km/h) and during an ABS stop. The pump motor makes a low humming noise during operation, which is normal.

270 STARTING AND OPERATING

WARNING!

• Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to an accident. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop. • The ABS cannot prevent the natural laws of phys- ics from acting on the vehicle, nor can it increase braking or steering efficiency beyond that af- forded by the condition of the vehicle brakes and tires or the traction afforded.

• The ABS cannot prevent accidents,

including those resulting from excessive speed in turns, following another vehicle too closely, or hydro- planing. Only a safe, attentive, and skillful driver can prevent accidents.

(Continued)

WARNING! (Continued)

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

CAUTION!

The ABS is subject to possible detrimental effects of electronic interference caused by improperly in- stalled aftermarket radios or telephones.

NOTE: During severe braking conditions, a pulsing sensation may occur and a clicking noise will be heard. This is normal, indicating that the ABS is functioning.

• Do not “ride” the brakes by resting your foot on the pedal. This could overheat the brakes and result in longer stopping dis- unpredictable braking action, tances, or brake damage. • When descending mountains or hills, repeated brak- ing can cause brake fade with loss of braking control. Avoid repeated heavy braking by downshifting the transmission or locking out overdrive whenever pos- sible. • Engines may idle at higher speeds during warm-up, which could cause rear wheels to spin and result in loss of vehicle control. Be especially careful while driving on slippery roads, in close-quarter maneuver- ing, parking, or stopping. • Do not drive too fast for road conditions, especially when roads are wet or slushy. A wedge of water can

STARTING AND OPERATING 271
build up between the tire tread and the road. This hydroplaning action can cause loss of traction, braking ability, and control. • After going through deep water or a car wash, brakes may become wet, resulting in decreased performance and unpredictable braking action. Dry the brakes by gentle, intermittent pedal action while driving at very slow speeds.

MULTI-DISPLACEMENT SYSTEM (MDS) (IF EQUIPPED) – 5.7L ENGINE ONLY This feature offers improved fuel economy by shutting off four of the engine’s eight cylinders during light load and cruise conditions. The system is automatic with no driver inputs or additional driving skills required. NOTE: The MDS system may take some time to return to full functionality after a battery disconnect.

272 STARTING AND OPERATING ELECTRONIC BRAKE CONTROL SYSTEM Your vehicle is equipped with an advanced electronic brake control system that includes the Anti-Lock Brake System (ABS), Traction Control System (TCS), Brake Assist System (BAS), Electronic Roll Mitigation (ERM), and Electronic Stability Program (ESP). All five of these systems work together to enhance vehicle stability and control in various driving conditions. Also, your vehicle is equipped with Trailer Sway Control (TSC) and, if it has four-wheel drive with the NV245
two-speed transfer case, Hill Start Assist (HSA) and Hill Descent Control (HDC). Anti-Lock Brake System (ABS)

This system aids the driver in maintaining vehicle control under adverse braking conditions. The system controls hydraulic brake pressure to prevent wheel lock-up and

help avoid skidding on slippery surfaces during braking. Refer to “Anti-Lock Brake System” in Section 5 of this manual.

WARNING!

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

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

STARTING AND OPERATING 273

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

274 STARTING AND OPERATING

WARNING!

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

Electronic Roll Mitigation (ERM) This system anticipates the potential for wheel lift by monitoring the driver’s steering wheel input and the speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicle speed

lift,

are sufficient to potentially cause wheel it then applies the brake of the appropriate wheel and may also reduce engine power to lessen the chance that wheel lift will occur. ERM will only intervene during very severe or evasive driving maneuvers. ERM can only reduce the chance of wheel lift occurring during severe or evasive driving maneuvers. It cannot prevent wheel lift due to other factors such as road conditions, leaving the roadway or striking objects or other vehicles. NOTE: Anytime the ESP system is in the “Full Off” mode, ERM is disabled. Refer to “Electronic Stability Program (ESP)” for a complete explanation of the avail- able ESP modes.

WARNING!

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

Electronic Stability Program (ESP)

This system enhances directional control and stability of the vehicle under various driving conditions. ESP cor- rects for oversteering or understeering of the vehicle by applying the brake of the appropriate wheel to assist in

STARTING AND OPERATING 275
counteracting the oversteer or understeer condition. En- gine power may also be reduced to help the vehicle maintain the desired path. ESP uses sensors in the vehicle to determine the vehicle path intended by the driver and compares it to the actual path of the vehicle. When the actual path does not match the intended path, ESP applies the brake of the appropri- ate wheel to assist in counteracting the oversteer or understeer condition. • Oversteer - when the vehicle is turning more than • Understeer - when the vehicle is turning less than

appropriate for the steering wheel position.

The “ESP/TCS Indicator Light” located in the instrument cluster will start to flash as soon as the tires lose traction and the ESP system becomes active. The “ESP/TCS Indicator Light” also flashes when the TCS is active. If the

276 STARTING AND OPERATING “ESP/TCS Indicator Light” begins to flash during accel- eration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.

WARNING!

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

The ESP system has three available operating modes in 4WD HIGH range, two available operating modes on two-wheel drive vehicles, and one operating mode in 4WD LOW range. High Range (Four-Wheel Drive Models) or Two-Wheel Drive Models

On This is the normal operating mode for ESP in 4WD HIGH range and in two-wheel drive vehicles. Whenever the vehicle is started or the transfer case (if equipped) is shifted from 4WD LOW range or NEUTRAL back to 4WD HIGH range, the ESP system will be in this “On” mode. This mode should be used for most driving situations. ESP should only be turned to “Partial Off” or “Full Off” mode for specific reasons as noted below.

Partial Off This mode is entered by momentarily pressing the “ESP OFF” switch. When in “Partial Off” mode, the TCS portion of ESP, except for the “limited slip” feature described in the TCS section, has been disabled and the “ESP/TCS Indicator Light” will be illuminated. All other stability features of ESP function normally. This mode is intended to be used if the vehicle is in deep snow, sand, or gravel conditions and more wheel spin than ESP would normally allow is required to gain traction. To turn ESP on again, momentarily press the “ESP OFF” switch. This will restore the normal “ESP On” mode of operation.

STARTING AND OPERATING 277

ESP OFF Switch

NOTE: To improve the vehicle’s traction when driving with snow chains, or starting off in deep snow, sand, or gravel, it may be desirable to switch to the “Partial Off” mode by pressing the “ESP OFF” switch. Once the situation requiring ESP to be switched to the “Partial Off”

278 STARTING AND OPERATING mode is overcome, turn ESP back on by momentarily pressing the “ESP OFF” switch. This may be done while the vehicle is in motion. Full Off (Four-Wheel Drive Models Only) This mode is intended for off-highway or off-road use when ESP stability features could inhibit vehicle maneu- verability due to trail conditions. This mode is entered by pressing and holding the “ESP OFF” switch for five seconds when the vehicle is stopped and the engine is running. After five seconds, the “ESP/TCS Indicator Light” will illuminate, and the “ESP OFF” message will appear in the Electronic Vehicle Information Center (EVIC). Refer to “Electronic Vehicle Information Center (EVIC)” in Section 4 of this manual for more information. In this mode, ESP and TCS, except for the “limited slip” feature described in the TCS section, are turned off until the vehicle reaches a speed of 40 mph (64 km/h). At 40 mph (64 km/h), the system returns to “Partial Off”

mode, described above. When the vehicle speed drops below 35 mph (56 km/h), the ESP system shuts off. ESP is deactivated at low vehicle speeds so that it will not interfere with off-road driving, but ESP function returns to provide the stability feature at speeds above 40 mph (64 km/h). The “ESP/TCS Indicator Light” will always be illuminated when ESP is off. To turn ESP on again, momentarily press the “ESP OFF” switch. This will restore the normal “ESP On” mode of operation. NOTE: The “ESP OFF” message will display, and the audible chime will sound, when the shift lever is placed in the PARK position from any other position, and then moved out of the PARK position. This will occur even if the message was previously cleared.

WARNING!

With the ESP switched off, the enhanced vehicle stability offered by ESP and ERM are unavailable. In an emergency evasive maneuver, the ESP and ERM systems will not engage to assist in maintaining stability. The “Full Off” ESP mode is intended for off-road use only.

4WD Low Range

Full Off This is the normal operating mode for ESP in 4WD LOW range. Whenever the vehicle is started in 4WD LOW range, or the transfer case (if equipped) is shifted from 4WD HIGH range or NEUTRAL to 4WD LOW range, the ESP system will be in this “Full Off” mode. In 4WD LOW range, ESP and TCS, except for the “limited slip” feature described in the TCS section, are turned off until the vehicle reaches a speed of 40 mph (64 km/h). At 40 mph

STARTING AND OPERATING 279
(64 km/h), the normal ESP stability function returns, but TCS remains off. When the vehicle speed drops below 35 mph (56 km/h), the ESP system shuts off. ESP is deactivated at low vehicle speeds in 4WD LOW range so that it will not interfere with off-road driving, but ESP function returns to provide the stability feature at speeds above 40 mph (64 km/h). The “ESP/TCS Indicator Light” will always be illuminated in 4WD LOW range when ESP is off. NOTE: The “ESP OFF” message will display, and the audible chime will sound, when the shift lever is placed in the PARK position from any other position, and then moved out of the PARK position. This will occur even if the message was previously cleared

280 STARTING AND OPERATING

WARNING!

With the ESP switched off, the enhanced vehicle stability offered by ESP and ERM are unavailable. In an emergency evasive maneuver, the ESP and ERM systems will not engage to assist in maintaining stability. The “Full Off” mode is intended for off- road use only.

Trailer Sway Control (TSC) TSC uses sensors in the vehicle to recognize an exces- sively swaying trailer and will take the appropriate actions to attempt to stop the sway. The system may reduce engine power and apply the brake of the appro- priate wheel(s) to counteract the sway of the trailer. TSC will become active automatically once an excessively swaying trailer is recognized. No driver action is re- quired. Note that TSC cannot stop all trailers from swaying. Always use caution when towing a trailer and

follow the trailer tongue weight recommendations. Refer to “Trailer Towing” in Section 5 of this manual. When TSC is functioning, the “ESP/TCS Indicator Light” will flash, the engine power may be reduced and you may feel the brakes being applied to individual wheels to attempt to stop the trailer from swaying. TSC is disabled when the ESP system is in the “Partial Off” or “Full Off” modes.

WARNING!

If TSC activates while driving, slow the vehicle down, stop at the nearest safe location, and adjust the trailer load to eliminate trailer sway.

Hill Start Assist (HSA) – Four-Wheel Drive Models With NV245 Two–Speed Transfer Case Only The HSA system is designed to assist the driver when starting a vehicle from a stop on a hill. HSA will maintain the level of brake pressure the driver applied for a short

period of time after the driver takes their foot off of the brake pedal. If the driver does not apply the throttle during this short period of time, the system will release brake pressure and the vehicle will roll down the hill. The system will release brake pressure in proportion to the amount of throttle applied as the vehicle starts to move in the intended direction of travel. HSA Activation Criteria The following criteria must be met in order for HSA to activate: • Vehicle must be stopped. • Vehicle must be on a 8% grade or greater hill. • Gear selection matches vehicle uphill direction (i.e., vehicle facing uphill is in forward gear; vehicle back- ing uphill is in REVERSE gear).

STARTING AND OPERATING 281
HSA will work in REVERSE and all forward gears when the activation criteria have been met. The system will not activate if the vehicle is placed in NEUTRAL or PARK.

WARNING!

There may be situations on minor hills (i.e., less than 8%), with a loaded vehicle, or while pulling a trailer, when the system will not activate and slight rolling may occur. This could cause a collision with another vehicle or object. Always remember the driver is responsible for braking the vehicle.

Towing with HSA HSA will provide assistance when starting on a grade when pulling a trailer.

282 STARTING AND OPERATING

WARNING!

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

(Continued)

WARNING! (Continued)

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

HSA Off If you wish to turn off the HSA system, it can be done using the Customer Programmable Features in the Elec- tronic Vehicle Information Center (EVIC). Refer to “Elec- tronic Vehicle Information Center (EVIC)” in Section 4 of this manual.

Hill Descent Control (HDC) – Four-Wheel Drive Models With NV245 Two–Speed Transfer Case Only HDC maintains vehicle speed while descending hills during off-road driving situations and is available in 4WD LOW range only. To enable HDC (transfer case must be in 4WD LOW range), press the HDC switch. If the HDC switch is pressed when the vehicle is not in 4WD LOW range, the light in the switch will flash for five seconds and HDC will not be enabled.

STARTING AND OPERATING 283

Hill Descent Switch

When HDC is properly enabled, the message “HILL DESCENT CONTROL” will appear in the EVIC and the light in the switch will be illuminated. HDC will auto- matically apply the brakes to control downhill speed when necessary. HDC has the capability to sense terrain

284 STARTING AND OPERATING and will only activate when the vehicle is descending a hill. It will usually not activate on level ground. The HDC speed may be adjusted by the driver to suit the driving conditions. The speed corresponds to the trans- mission gear selected. • 1st = 1 mph (1.6 km/h) • 2nd = 2.5 mph (4 km/h) • 3rd = 4 mph (6 km/h) • 4th = 5.5 mph (9 km/h) • 5th = 7.5 mph (12 km/h) • REVERSE = 1 mph (1.6 km/h) • NEUTRAL = 2.5 mph (4 km/h) • PARK = HDC will not function

HDC also has the capability to sense rough terrain, and will automatically adjust to a slightly slower set speed [about 0.3 mph (0.5 km/h) than normal.] HDC operation can be overridden with brake application to slow the vehicle down below the HDC control speed. Conversely, if more speed is desired during HDC control, the accelerator pedal will increase vehicle speed in the usual manner. When either the brake or the accelerator is released, HDC will control the vehicle back to the origi- nal set speed. HDC is intended for low speed off-road driving only. At vehicle speeds above 30 mph (48 km/h), HDC will no longer function. When the vehicle speed drops below 30 mph (48 km/h), HDC function will automatically resume and the vehicle speed will return to the chosen set speed.

WARNING!

HDC is only intended to assist the driver in control- ling vehicle speed when descending hills. The driver must remain attentive to the driving conditions and is responsible for maintaining a safe vehicle speed.

ESP/BAS Warning Light and ESP/TCS Indicator Light

The malfunction indicator light for the ESP is combined with the BAS indicator. The “ESP/ BAS Warning Light” and the “ESP/TCS Indi- cator Light” in the instrument cluster both come on when the ignition switch is turned to the ON position. They should both go out with the engine running.

STARTING AND OPERATING 285
If the “ESP/BAS Warning Light” comes on continuously with the engine running, a mal- function has been detected in either the ESP or the BAS system, or both. If this light remains on after several ignition cycles, and the vehicle has been driven several miles at speeds greater than 30 mph (48 km/h), see your authorized dealer as soon as possible to have the problem diagnosed and corrected. NOTE: • The “ESP/TCS Indicator Light” and the “ESP/BAS Warning Light” come on momentarily each time the ignition switch is turned ON. • Each time the ignition is turned ON, the ESP System • The ESP Control System will make buzzing or clicking sounds when it is active. This is normal; the sounds will stop when the ESP becomes inactive following the maneuver that caused the ESP activation.

290 STARTING AND OPERATING Tire Loading and Tire Pressure

Tire Placard Location NOTE: The proper cold tire inflation pressure is listed on the driver’s side B-Pillar. Tire and Loading Information Placard

This placard tells you important information about the: 1) number of people that can be carried in the vehicle 2) total weight your vehicle can carry 3) tire size designed for your vehicle 4) cold tire inflation pressures for the front, rear, and spare tires. Loading The vehicle maximum load on the tire must not exceed the load carrying capacity of the tire on your vehicle. You will not exceed the tire’s load carrying capacity if you adhere to the loading conditions, tire size, and cold tire inflation pressures specified on the Tire and Loading Information placard and in the “Vehicle Loading” section of this manual.

Tire and Loading Information Placard

NOTE: Under a maximum loaded vehicle condition, gross axle weight ratings (GAWRs) for the front and rear axles must not be exceeded. For further information on GAWRs, vehicle loading, and trailer towing, refer to “Vehicle Loading” in this section. To determine the maximum loading conditions of your vehicle, locate the statement “The combined weight of occupants and cargo should never exceed XXX lbs or XXX kg” on the Tire and Loading Information placard. The combined weight of occupants, cargo/luggage and trailer tongue weight (if applicable) should never exceed the weight referenced here. Steps for Determining Correct Load Limit 1. Locate the statement “The combined weight of occu- pants and cargo should never exceed XXX lbs or XXX kg” on your vehicle’s placard.

STARTING AND OPERATING 291
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and pas- sengers from XXX lbs or XXX kg. 4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if “XXX” amount equals 1,400 lbs (635 kg) and there will be five 150 lb (68 kg) passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (295 kg) (since 5 x 150 = 750, and 1400 – 750 = 650 lbs [295 kg]). 5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

• For the following example, the combined weight of occupants and cargo should never exceed 865 lbs (392 kg).

292 STARTING AND OPERATING 6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle. NOTE: • The following table shows examples on how to calcu- late total load, cargo/luggage, and towing capacities of your vehicle with varying seating configurations and number and size of occupants. This table is for illustration purposes only and may not be accurate for the seating and load carry capacity of your vehicle.
