To provide you with maximum comfort in the Automatic mode, during cold start-ups the blower fan will remain on low until the engine warms up. The blower will increase in speed and transition into Auto mode.
Manual Operation Override The system allows for manual selection of blower speed, air distribution mode, A/C status and recirculation con- trol. The blower fan speed can be set to any fixed speed by adjusting the blower control. The fan will now operate at a fixed speed until additional speeds are selected. This allows the front occupants to control the volume of air circulated in the vehicle and cancel the Auto mode. The operator can also select the direction of the airflow by selecting one of the available mode settings. A/C operation and Recirculation control can also be manually selected in Manual operation.
Operating Tips
NOTE: Refer to the chart at the end of this section for suggested control settings for various weather condi- tions. Summer Operation The engine cooling system must be protected with a high-quality antifreeze coolant to provide proper corro- sion protection and to protect against engine overheating. A solution of 50% OAT (Organic Additive Technology) coolant that meets the requirements of Chrysler Material Standard MS-12106 and 50% water is recommended. Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for proper coolant selection. Winter Operation Use of the air Recirculation mode during winter months is not recommended because it may cause window fogging.

Vacation Storage Any time you store your vehicle or keep it out of service (i.e., vacation) for two weeks or more, run the air conditioning system at idle for about five minutes in the fresh air and high blower setting. This will ensure adequate system lubrication to minimize the possibility of compressor damage when the system is started again. Window Fogging Interior fogging on the windshield can be quickly re- moved by turning the mode selector to Defrost. The Defrost/Floor mode can be used to maintain a clear windshield and provide sufficient heating. If side win- dow fogging becomes objectionable, increase blower speed to improve airflow and clearing of the side win- dows. Vehicle windows tend to fog on the inside in mild but rainy or humid weather.
periods, as fogging may occur.
382 UNDERSTANDING YOUR INSTRUMENT PANEL NOTE: • Recirculate without A/C should not be used for long • Automatic Temperature Controls (ATC) will automati- cally adjust the climate control settings to reduce or eliminate window fogging on the front windshield. When this occurs, recirculation will be unavailable.
Outside Air Intake Make sure the air intake, located directly in front of the windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they enter the plenum, they could plug the water drains. In Winter months, make sure the air intake is clear of ice, slush, and snow. A/C Air Filter The climate control system filters outside air containing dust, pollen and some odors. Strong odors cannot be totally filtered out. Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for filter replacement instruc- tions.

398 STARTING AND OPERATING
CAUTION! (Continued)
• Before shifting into any gear, make sure your foot is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while shifting out of PARK. Key Ignition Park Interlock This vehicle is equipped with a Key Ignition Park Inter- lock which requires the transmission to be in PARK before the engine can be turned off. This helps the driver avoid inadvertently leaving the vehicle without placing the transmission in PARK. This system also locks the transmission in PARK when- ever the ignition switch is in the OFF position.
Brake/Transmission Shift Interlock System This vehicle is equipped with a Brake Transmission Shift Interlock System (BTSI) that holds the shift lever in PARK unless the brakes are applied. To shift the transmission out of PARK, the engine must be running and the brake pedal must be pressed. The brake pedal must also be pressed to shift from NEUTRAL into DRIVE or REVERSE when the vehicle is stopped or moving at low speeds.

Fuel Economy Mode Switch
400 STARTING AND OPERATING Eight–Speed Automatic Transmission Your vehicle is equipped with a state of the art, fuel efficient eight-speed transmission. The electronic shift lever in this vehicle does not slide like a conventional shifter. Instead, the shift lever is spring loaded and moves forward and rearward, always returning to the center position after each gear is selected. The transmission gear (PRND) is displayed both on the shift lever and in the Electronic Vehicle Information Center (EVIC). To select a gear range, press the lock button on the shift lever and move the lever rearward or forward. You must press the brake pedal to shift the transmission out of PARK, or to shift from NEUTRAL into DRIVE or REVERSE when the vehicle is stopped or moving at low speeds (refer to “Brake/Transmission Shift Interlock System” in this sec- tion). To shift past multiple gear ranges at once (such as PARK to DRIVE), move the lever past the first (or second) detent. Select the DRIVE range for normal driving.
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). Only shift from DRIVE to PARK or REVERSE when the accelerator pedal is released and the vehicle is stopped. Be sure to keep your foot on the brake pedal when shifting between these gears. The transmission shift lever provides PARK, REVERSE, NEUTRAL, DRIVE and SPORT shift positions. Once in the DRIVE range, tapping the shift lever rearward will toggle between SPORT mode and DRIVE mode. You do not need to press the shift lever button when toggling between DRIVE and SPORT modes. Manual shifts can be made using the shift paddles mounted on the steering wheel. Pressing the shift paddles (-/+) while in the
DRIVE or SPORT position will manually select the trans- mission gear, and will display the current gear in the instrument cluster. Refer to ⬙Paddle Shift Mode⬙ in this section for further information.

STARTING AND OPERATING 401
Gear Ranges DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range. 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. PARK (P) This range supplements the parking brake by locking the transmission. The engine can be started in this range. Never attempt to use PARK while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. When parking on a level surface, you may shift the transmission into PARK first, and then apply the parking brake.
402 STARTING AND OPERATING When parking on a hill, apply the parking brake before shifting the transmission to PARK. As an added precau- tion, turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade. NOTE: On four-wheel drive vehicles be sure that the transfer case is in a drive position.
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully when parked to guard against vehicle move- ment and possible injury or damage. • Your vehicle could move and injure you and others if it is not in PARK. Make sure the transmission is in PARK before leaving the vehicle.
WARNING! (Continued)
• It is dangerous to shift out of PARK or NEUTRAL if the engine speed is higher than idle speed. If your foot is not firmly pressing the brake pedal, the vehicle could accelerate quickly forward or in re- verse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and your foot is firmly pressing the brake pedal. • Unintended movement of a vehicle could injure those in or near the vehicle. As with all vehicles, you should never exit a vehicle while the engine is running. Before exiting a vehicle, always apply the parking brake, shift the transmission into PARK, turn the engine OFF, and remove the Key Fob. When the ignition is in the OFF position, the

Do not coast in NEUTRAL and never turn off the ignition to coast down a hill. These are unsafe practices that limit your response to changing traffic or road conditions. You might lose control of the vehicle and have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other reason with the transmission in NEUTRAL can cause severe transmission damage. Refer to “Recreational Towing” in “Starting And Operating” and “Towing A Disabled Vehicle” in “What To Do In Emergencies” for further information.
STARTING AND OPERATING 405
DRIVE (D) This range should be used for most city and highway driving. It provides the smoothest upshifts and down- shifts, and the best fuel economy. The transmission automatically upshifts through all forward gears. The DRIVE position provides optimum driving characteris- tics under all normal operating conditions. When frequent transmission shifting occurs (such as when operating the vehicle under heavy loading condi- tions, in hilly terrain, traveling into strong head winds, or while towing heavy trailers), use the Paddle Shift switches (refer to ⬙Paddle Shift Mode⬙ in this section) to select a lower gear. Under these conditions, using a lower gear will improve performance and extend transmission life by reducing excessive shifting and heat buildup. During extremely cold temperatures (-22°F [-30°C] or below), transmission operation may be modified depend- ing on engine and transmission temperature as well as
406 STARTING AND OPERATING vehicle speed. Normal operation will resume once the transmission temperature has risen to a suitable level. SPORT (S) This mode alters the transmission’s automatic shift schedule for sportier driving. Upshift speeds are in- creased to make full use of available engine power. To switch between DRIVE and SPORT modes, tap the shift lever rearward. SPORT mode is only accessible from DRIVE. NOTE: When Sport Mode is enabled, the vehicle’s air suspension system will operate in “Aero” Mode. Please refer to “Quadra Lift” within this section for further information. Transmission Limp Home Mode Transmission function is monitored electronically for abnormal conditions. If a condition is detected that could result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may operate only in certain gears, or may not shift at all. Vehicle performance may be severely degraded and the engine may stall. In some situations, the transmission may not re-engage if the engine is turned off and restarted. The Malfunction Indicator Light (MIL) may be illuminated. A message in the instrument cluster will inform the driver of the more serious conditions, and indicate what actions may be necessary. In the event of a momentary problem, the transmission can be reset to regain all forward gears by performing the following steps: NOTE: In cases where the instrument cluster message indicates the transmission may not re-engage after en- gine shutdown, perform this procedure only in a desired location (preferably, at your authorized dealer). 1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not,
shift the transmission to NEUTRAL.
3. Turn the ignition switch to the OFF position. On vehicles with Keyless Enter-N-Go™, press and hold the ignition switch until the engine turns OFF.
4. Wait approximately 30 seconds. 5. Restart the engine. 6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to normal operation.
NOTE: Even if the transmission can be reset, we recom- mend that you visit your authorized dealer at your earliest possible convenience. Your authorized dealer has diagnostic equipment to determine if the problem could recur.
STARTING AND OPERATING 407
If the transmission cannot be reset, authorized dealer service is required. Paddle Shift Mode Paddle Shift mode is a driver-interactive transmission feature providing manual shift control, giving you more control of the vehicle. Paddle Shift allows you to maxi- mize engine braking, eliminate undesirable upshifts and downshifts, and improve overall vehicle performance. This system can also provide you with more control during passing, city driving, cold slippery conditions, mountain driving, trailer towing, and many other situa- tions. Operation When the transmission is in DRIVE or SPORT mode, it will operate automatically, shifting between the eight available gears. To engage Paddle Shift mode, simply tap one of the steering wheel-mounted shift paddles (+/-)408 STARTING AND OPERATING while in DRIVE or SPORT mode. Tapping (-) to enter Paddle Shift mode will downshift the transmission to the next lower gear, while using (+) to enter Paddle Shift mode will retain the current gear. When Paddle Shift mode is active, the current transmission gear is displayed in the instrument cluster. In Paddle Shift mode, the transmission will shift up or down when (+/-) is manually selected by the driver, unless an engine lugging or overspeed condition would result. It will remain in the selected gear until another upshift or downshift is chosen, except as described below. • The transmission will automatically downshift as the vehicle slows (to prevent engine lugging) and will display the current gear.
• The transmission will automatically downshift to first gear when coming to a stop. After a stop, the driver should manually upshift (+) the transmission as the vehicle is accelerated. • You can start out, from a stop, in first or second gear (or third gear, in 4LO range, Snow mode, or Sand mode). Tapping (+) at a stop will allow starting in second gear. Starting out in second gear is helpful in snowy or icy conditions. • If a requested downshift would cause the engine to • The system will ignore attempts to upshift at too low • Holding the (-) paddle depressed will progressively downshift the transmission to the lowest gear possible at the current speed.

FOUR-WHEEL DRIVE OPERATION
Quadra-Trac I® Operating Instructions/ Precautions — If Equipped The Quadra-Trac I® 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.
410 STARTING AND OPERATING NOTE: The Quadra-Trac I® system is not appropriate for conditions where 4WD LOW range is recommended. Refer to “Off-Road Driving Tips” in “Starting and Oper- ating” for further information. Quadra-Trac II® Operating Instructions/ Precautions — If Equipped The Quadra-Trac II® transfer case is fully automatic in the normal driving 4WD AUTO mode. The Quadra-Trac II® 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 NEUTRAL (N) position without first fully engaging the parking brake. The transfer case NEUTRAL (N) position disengages both the front and rear drive shafts 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.
Shift Positions For additional information on the appropriate use of each 4WD system mode position, see the information below: 4WD AUTO This range is used on surfaces such as ice, snow, gravel, sand, and dry hard pavement.
STARTING AND OPERATING 411
NOTE: Refer to “Selec-Terrain® – If Equipped” in “Start- ing and Operating” for further information on the vari- ous positions and their intended usages. NEUTRAL This range disengages the driveline from the powertrain. It is to be used for flat towing behind another vehicle. Refer to “Recreational Towing” in “Starting and Operat- ing” for further information.WARNING!
You or others could be injured or killed if you leave the vehicle unattended with the power transfer unit in the NEUTRAL (N) position without first fully engaging the parking brake.

Quadra-Drive® II System — If Equipped The optional Quadra-Drive® II System features two torque transfer couplings. The couplings include an Electronic Limited-Slip Differential (ELSD) rear axle and the Quadra-Trac II® transfer case. The optional ELSD axle is fully automatic and requires no driver input to operate. Under normal driving conditions, the unit func- tions as a standard axle, 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
418 STARTING AND OPERATING other, torque will automatically transfer from the wheel that has less traction, to the wheel that has traction. While the transfer case and axle coupling differ in design, their operation is similar. Follow the Quadra-Trac II® transfer case shifting information, preceding this section, for shifting this system.

the opposite side of the vehicle.
NOTE: • It may be necessary to apply additional force to individual tabs to make sure they are fully engaged. • Do not use any tools to apply additional force to the tabs as damage to the upper and lower fascias may result.
4. Reinstall the seven quarter turn fasteners. Quadra-Lift™ — If Equipped When off-roading, it is recommended that the lowest useable vehicle height that will clear the current obstacle or terrain be selected. The vehicle height should then be raised as required by the changes in terrain.
STARTING AND OPERATING 431
The Selec-Terrain™ switch will automatically change the vehicle to the optimized height based on the Selec- Terrain™ switch position. The vehicle height can be changed from the default height for each Selec-Terrain™ mode by normal use of the air suspension switches. Refer to “Quadra-Lift™ – If Equipped” in “Starting and Oper- ating” for further information. 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.432 STARTING AND OPERATING
CAUTION!
Do not drive in 4WD-LOW Range on dry pavement; driveline damage may result. 4WD-LOW Range locks front and rear drivelines together and does not allow for differential action between the front to rear driveshafts. Driving in 4WD-LOW on pavement will cause driveline binding; use only on wet or slippery surfaces.
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.
NOTE: Your vehicle is capable of water fording in up to 20 inches (51 cm) of water, while crossing small rivers or streams. To maintain optimal performance of your vehi- cle’s heating and ventilation system it is recommended to switch the system into recirculation mode during water fording.
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 inches (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 inches (51 cm), and reduce speed appropriately to minimize wave effects. Maximum speed in 20 inches (51 cm) of water is less than 5 mph (8 km/h).
STARTING AND OPERATING 433
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 “Starting and Operating” for further information. 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.
434 STARTING AND OPERATING 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. 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. 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.

required.
• Completely inspect the underbody of your vehicle. Check tires, body structure, steering, suspension, and exhaust system for damage. • Inspect the radiator for mud and debris and clean as • 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 lines, brake hoses, axle pinion seals, and to fuel propeller shafts. • After extended operation in mud, sand, water, or similar dirty conditions, have the radiator, fan, brake rotors, wheels, brake linings, and axle yokes inspected and cleaned as soon as possible.
436 STARTING AND OPERATING
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 a collision. 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.
POWER STEERING
3.6L Engine Your vehicle is equipped with an electro-hydraulic power steering system that will give you good vehicle response
and increased ease of maneuverability in tight spaces. The system will vary its assist to provide light efforts while parking and good feel while driving. If the electro- hydraulic power steering system experiences a fault that prevents it from providing power steering assist, then the system will provide mechanical steering capability.
CAUTION!
Extreme steering maneuvers may cause the electri- cally driven pump to reduce or stop power steering assistance in order to prevent damage to the system. Normal operation will resume once the system is allowed to cool.
If the “SERVICE POWER STEERING” message and a flashing icon are displayed on the EVIC screen, it indicates that the vehicle needs to be taken to the dealer for service. It is likely the
vehicle has lost power steering assistance. Refer to “Elec- tronic Vehicle Information (EVIC)” in “Understanding Your Instrument Panel” for further information. If the “POWER STEERING HOT” message and an icon are displayed on the EVIC screen, indicates that extreme steering maneuvers may have occurred, which caused an over temperature condition in the power steering system. You will lose power steering assistance momentarily until the over temperature condition no longer exists. Once driving conditions are safe, then pull over and let vehicle idle for a few moments until the light turns off. Refer to “Electronic Vehicle Information (EVIC)” in “Understanding Your Instrument Panel” for further information.
it
STARTING AND OPERATING 437
NOTE: • Even if power steering assistance is no longer opera- tional, it is still possible to steer the vehicle. Under these conditions there will be a substantial increase in steering effort, especially at very low vehicle speeds and during parking maneuvers. • If the condition persists, see your authorized dealer for
service.
5.7L Engine 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.
438 STARTING AND OPERATING 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. NOTE: • Increased noise levels at the end of the steering 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 steer- ing 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.
WARNING!
Continued operation with reduced power steering assist could pose a safety risk to yourself and others. Service should be obtained as soon as possible.
CAUTION!
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 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.
CAUTION!
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.
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 manufacturer’s recommended power steering fluid.
STARTING AND OPERATING 439
If necessary, add fluid to restore to the proper indicated level. With a clean cloth, wipe any spilled fluid from all surfaces. Refer to “Fluids, Lubricants, and Genuine Parts” in “Maintaining Your Vehicle” for further informa- tion.FUEL SAVER TECHNOLOGY 5.7L ENGINE ONLY — IF EQUIPPED 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: This system may take some time to return to full functionality after a battery disconnect.
PARKING BRAKE Before leaving the vehicle, make sure that the parking brake is fully applied and place the shift lever in the PARK position.
440 STARTING AND OPERATING The foot operated parking brake is located below the lower left corner of the instrument panel. To apply the park brake, firmly push the park brake pedal fully. To release the parking brake, press the park brake pedal a second time and let your foot up as you feel the brake disengage.
Parking Brake
When the parking brake is applied with the ignition switch in the ON position, the “Brake Warning Light” in the instrument cluster will illuminate. NOTE: • When the parking brake is applied and the transmis- sion is placed in gear, the “Brake Warning Light” will flash. If vehicle speed is detected, a chime will sound to alert the driver. Fully release the parking brake before attempting to move the vehicle. • This light only shows that the parking brake is ap- plied. It does not show the degree of brake application.
When parking on a hill, it is important to turn the front wheels toward the curb on a downhill grade and away from the curb on an uphill grade. 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. The parking brake should always be applied whenever the driver is not in the vehicle.
WARNING!
• Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully when parked to guard against vehicle move- ment and possible injury or damage. • When leaving the vehicle, always remove the Key Fob from the ignition and lock your vehicle. • Never leave children alone in a vehicle, or with access to an unlocked vehicle. Allowing children to be in a vehicle unattended is dangerous for a number of reasons. A child or others could be seriously or fatally injured. Children should be

442 STARTING AND OPERATING
WARNING! (Continued)
• 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.
CAUTION!
If the “Brake Warning Light” remains on with the parking brake released, a brake system malfunction is indicated. Have the brake system serviced by an authorized dealer immediately.
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 Control (ESC). All five of these systems work together to enhance vehicle stability and control in various driving conditions. Also, your vehicle may be equipped with Trailer Sway Control (TSC), Hill Start Assist (HSA), Ready Alert Braking (RAB), Rain Brake Support (RBS) and, if it has four-wheel drive with the MP 3023 two-speed transfer case, Hill Descent Control (HDC), Selec Speed Control (SSC). 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.
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 Anti-Lock Brake System conducts a low speed self- test at about 12 mph (20 km/h). If for any reason your foot is on the brake when the vehicle reaches 12 mph (20 km/h), this check will be delayed until 25 mph (40 km/h). The Anti-Lock Brake System pump motor runs during the self-test, and during an ABS stop, to provide the regulated hydraulic pressure. The motor pump makes a low humming noise during operation; this is normal.
STARTING AND OPERATING 443
WARNING!
• Pumping of the Anti-Lock Brakes will diminish their effectiveness and may lead to a collision. Pumping makes the stopping distance longer. Just press firmly on your brake pedal when you need to slow down or stop. • The Anti-Lock Brake System (ABS) cannot prevent the natural laws of physics from acting on the vehicle, nor can they increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. • The ABS cannot prevent collisions, including those resulting from excessive speed in turns, following another vehicle too closely, or hydroplaning. • 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.
444 STARTING AND OPERATING
CAUTION!
The Anti-Lock Brake System is subject to possible detrimental effects of electronic interference caused by improperly installed aftermarket radios or tele- phones.
NOTE: During severe braking conditions, a pulsing sen- sation may occur and a clicking noise will be heard. This is normal, indicating that the Anti-Lock Brake System is functioning. 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, Brake Limited Differential (BLD), 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 ESC system is in the “Partial Off” mode. Refer to “Elec- tronic Stability Control (ESC)” in this section for further information. 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.
WARNING!
• The BAS cannot prevent the natural laws of phys- ics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. • The BAS cannot prevent collisions, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning. • 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.
STARTING AND OPERATING 445
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’s speed are sufficient to potentially cause wheel it then applies the appropriate brake 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.
lift,
446 STARTING AND OPERATING
WARNING!
Many factors, such as vehicle loading, road condi- tions, and driving conditions, influence the chance that wheel lift or rollover may occur. ERM cannot prevent all wheel lift or rollovers, especially those that involve leaving the roadway or striking objects or other vehicles. The capabilities of an ERM- 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.
Electronic Stability Control (ESC) This system enhances directional control and stability of the vehicle under various driving conditions. ESC cor- rects for oversteering or understeering of the vehicle by applying the brake of the appropriate wheel to assist in
counteracting the oversteer or understeer condition. En- gine power may also be reduced to help the vehicle maintain the desired path. ESC 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, ESC applies the brake of the appro- priate 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 “ESC Activation/Malfunction Indicator Light” lo- cated in the instrument cluster will start to flash as soon as the tires lose traction and the ESC system becomes active. The “ESC Activation/Malfunction Indicator Light” also flashes when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” begins to flash during acceleration, ease up on the accelerator and apply as little throttle as possible. Be sure to adapt your speed and driving to the prevailing road conditions.
WARNING!
The Electronic Stability Control (ESC) cannot pre- vent the natural laws of physics from acting on the vehicle, nor can it increase the traction afforded by prevailing road conditions. ESC cannot prevent col- lisions, including those resulting from excessive speed in turns, driving on very slippery surfaces, or hydroplaning. ESC also cannot prevent collisions resulting from loss of vehicle control due to inappro- priate driver input for the conditions. Only a safe, attentive, and skillful driver can prevent collisions. The capabilities of an ESC equipped vehicle must

never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others.
The ESC system has two available operating modes in 4WD HIGH range and 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 ESC 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 ESC system will be in this “On”
448 STARTING AND OPERATING mode. This mode should be used for most driving situations. ESC should only be turned to “Partial Off” mode for specific reasons as noted below. Partial Off This mode is entered by momentarily pressing the “ESC OFF” switch. When in “Partial Off” mode, the TCS portion of ESC, except for the BLD feature described in the TCS section, has been disabled and the “ESC Off Indicator Light” will be illuminated. All other stability features of ESC 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 ESC would nor- mally allow is required to gain traction. To turn ESC on again, momentarily press the “ESC OFF” switch. This will restore the normal “ESC On” mode of operation.
NOTE: To improve the vehicle’s traction when driving with snow chains, or starting off in deep snow, sand, or gravel, it may be desirable to switch to the “Partial Off” mode by pressing the “ESC OFF” switch. Once the situation requiring ESC to be switched to the “Partial Off” mode is overcome, turn ESC back on by momen- tarily pressing the “ESC OFF” switch. This may be done while the vehicle is in motion.
WARNING!
• When in “Partial Off” mode, the TCS functionality of ESC, (except for the limited slip feature de- scribed in the TCS section), has been disabled and the “ESC Off Indicator Light” will be illuminated. When in “Partial Off” mode, the engine power reduction feature of TCS is disabled, and the
