• Depress the brake pedal and turn the ignition switch to ON/RUN
with the engine shut off.
• Shift the transmission into NEUTRAL.
• Shift the transfer case into NEUTRAL by holding down the
NEUTRAL Pin switch for four
seconds until the LED starts to
blink. The LED will stop blinking
and remain on when the shift is
complete.
• Start the engine and shift into DRIVE to ensure there is no vehicle movement.
• Shut the engine off and shift the transmission into PARK.
• Place the ignition switch in the OFF position and remove the key.
• Apply the parking brake, attach the vehicle to the tow vehicle with a tow bar and release the parking brake.
• Refer to your Owner's Manual on the DVD for further details.
CAUTION!
Towing with the rear wheels on the ground (while the driveshaft is
connected) will cause severe transmission damage. Damage from
improper towing is not covered under the New Vehicle Limited
Warranty.
WARNING!
• If the driveshaft is removed, the vehicle can roll even if the transmission is in PARK, which could cause serious injury or death.
UTILITY
78

• Please note that the TPMS is not a substitute for proper tiremaintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
• Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS
malfunction indicator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously illuminated. This
sequence will continue each time the vehicle is restarted as long as the
malfunction exists.
• When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
NOTE: Tire pressures change by approximately 1 psi (7 kPa) per 12° F (7° C)
of air temperature change. Keep this in mind when checking tire pressure
inside a garage, especially in the Winter. Example: If garage temperature is
68°F (20°C) and the outside temperature is 32°F (0°C), then the cold tire
inflation pressure should be increased by 3 psi (21 kPa), which equals 1 psi
(7 kPa) for every 12°F (7°C) for this outside temperature condition.
CAUTION!
The TPMS has been optimized for the original equipment tires and
wheels. TPMS pressures and warning have been established for the
tire size equipped on your vehicle. Undesirable system operation or
sensor damage may result when using replacement equipment that is
not of the same size, type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or balance beads if
your vehicle is equipped with a TPMS, as damage to the sensors may
result.
- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on and a warning chime sounds while driving, safely pull over and stop the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the temperature
reading does not return to normal, turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.

Oil Change IndicatorMessage• If an “oil change” message (shown as CHAngE OIL) appears and a single chime sounds, it is time for your next required oil change.
Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending
overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this
heat.
• You can also turn the temperature control to maximum heat, the mode control to floor and the blower control to high. This allows the heater core
to act as a supplement to the radiator and aids in removing heat from the
engine cooling system.
CAUTION!
Driving with a hot cooling system could damage your vehicle. If the
temperature gauge reads 240°F (116 °C) or greater pull over and stop
the vehicle. Idle the vehicle with the air conditioner turned off until the
pointer drops back into the normal range 200–230°F (93–110°C). If
the pointer remains at 240°F (116°C) or greater and you hear a chime,
turn the engine off immediately and call for service.
WARNING!
You or others can be badly burned by hot engine coolant (antifreeze)
or steam from your radiator. If you see or hear steam coming from
under the hood, do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure cap when the
radiator or coolant bottle is hot.

WARNING!
• Do not attempt to change a tire on the side of the vehicle close tomoving traffic. Pull far enough off the road to avoid the danger of
being hit when operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never put any
part of your body under a vehicle that is on a jack. If you need to
get under a raised vehicle, take it to a service center where it can be
raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The
vehicle should be jacked on a firm level surface only. Avoid ice or
slippery areas.
• Do not attempt to change a tire on the side of the vehicle close to moving traffic, pull far enough off the road to avoid being hit when
operating the jack or changing the wheel.
• Carefully follow these tire changing warnings to help prevent personal injury or damage to your vehicle.
• Always park on a firm, level surface as far from the edge of the
roadway as possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in PARK; a manual transmission in REVERSE.
• Never start or run the engine with the vehicle on a jack.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack.
• Only use the jack in the positions indicated and for lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.
• Raising the vehicle higher than necessary can make the vehicle less stable and cause a collision. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to remove the tire.
• A loose tire or jack, thrown forward in a collision or hard stop, could endanger the occupants of the vehicle. Always stow the jack parts
and the spare tire in the places provided.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the lug nuts fully until the vehicle is lowered to the ground.

JUMP-STARTING
• If your vehicle has a discharged battery it can be jump-started using aset of jumper cables and a battery in another vehicle or by using a
portable battery booster pack.
• Jump-starting can be dangerous if done improperly so please follow the procedures in this section carefully.
NOTE: When using a portable battery booster pack follow the
manufacturer’s operating instructions and precautions.
Preparations for Jump-Start
• The battery in your vehicle is located in the front of the engine compartment, behind the left headlight assembly.
NOTE: The positive battery post is covered with a protective cap. Lift up on
the cap to gain access to the positive battery post.
• Set the parking brake, shift the automatic transmission into PARK andturn the ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• If using another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the
ignition is OFF.
Jump-Starting Procedure
• Connect the positive (+) end of the jumper cable to the positive (+) postof the discharged vehicle.
WHAT TO DO IN EMERGENCIES
89

• Connect the opposite end of the positive (+) jumper cable to the positive(+) post of the booster battery.
• Connect the negative end (-) of the jumper cable to the negative (-) post of the booster battery.
• Connect the opposite end of the negative (-) jumper cable to a good engine ground (exposed metal part of the discharged vehicle’s engine)
away from the battery and the fuel injection system.
• Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start the engine in the vehicle with the
discharged battery.
Once the engine is started, remove the jumper cables in the reverse
sequence:
• Disconnect the negative (-) jumper cable from the engine ground of the vehicle with the discharged battery.
• Disconnect the negative end (-) of the jumper cable from the negative (-) post of the booster battery.
• Disconnect the opposite end of the positive (+) jumper cable from the positive (+) post of the booster battery.
• Disconnect the positive (+) end of the jumper cable from the positive (+) post of the discharged vehicle.
• If frequent jump-starting is required to start your vehicle you should have the battery and charging system inspected at your authorized dealer.
CAUTION!
• Do not use a portable battery booster pack or any other boostersource with a system voltage greater than 12 Volts or damage to the
battery, starter motor, alternator or electrical system may occur.
• Failure to follow these procedures could result in damage to the charging system of the booster vehicle or the discharged vehicle.
• Accessories that can be plugged into the vehicle power outlets draw power from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long enough, the
vehicle’s battery will discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
WARNING!
• When temperatures are below the freezing point, electrolyte in adischarged battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode and cause personal
injury. Battery temperature must be brought above the freezing
point before attempting a jump-start.

WARNING!(Continued)
• Take care to avoid the radiator cooling fan whenever the hood israised. It can start anytime the ignition switch is on. You can be
injured by moving fan blades.
• Remove any metal jewelry, such as watch bands or bracelets, that might make an inadvertent electrical contact. You could be severely
injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep
open flames or sparks away from the battery.
• Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property damage due to battery explosion.
• Do not connect the cable to the negative post (-) of the discharged battery. The resulting electrical spark could cause the battery to
explode and could result in personal injury.
SHIFT LEVER OVERRIDE
• If a malfunction occurs and theshift lever cannot be moved out of
the PARK position, you can use
the following procedure to
temporarily move the shift lever:
• To access the shift lever override, remove the override cover
located on the PRNDL bezel, next
to the shift lever.
• Firmly set the parking brake.
• Turn the ignition switch to the ACC or ON position without
starting the engine.
• Press and maintain firm pressure on the brake pedal.
• Using a screwdriver or similar tool, press and hold the override tab through the access port on the center console.
• Move the shift lever into the NEUTRAL position.
• The vehicle may then be started in NEUTRAL.
• Reinstall the override cover.

FREEING A STUCK VEHICLE
• If your vehicle becomes stuck in mud, sand or snow, it can often bemoved by a rocking motion. Turn your steering wheel right and left to
clear the area around the front wheels. Then shift back and forth
between REVERSE and DRIVE. Using minimal accelerator pedal pressure
to maintain the rocking motion, without spinning the wheels, is most
effective.
NOTE: If your vehicle is equipped with Traction Control or Electronic
Stability Control (ESC), turn the system OFF before attempting to “rock” the
vehicle.
CAUTION!
• Racing the engine or spinning the wheels 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 prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by moving between REVERSE and DRIVE, do not spin the wheels faster than 15 mph (24 km/h), or
drivetrain damage may result.
• Revving the engine or spinning the wheels too fast may lead to transmission overheating and failure. It can also damage the tires.
Do not spin the wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces generated by excessive
wheel speeds may cause damage, or even failure, of the axle and tires.
A tire could explode and injure someone. Do not spin your vehicle's
wheels faster than 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping when you are stuck and do not let
anyone near a spinning wheel, no matter what the speed.
