4. Finish tightening the lug nuts. Push down on the wrench while at the
end of the handle for increased leverage. Tighten the lug nuts in a star
pattern until each nut has been tightened twice. The correct tightness of
each lug nut is 95 ft/lbs (130 N·m). If in doubt about the correct
tightness, have them checked with a torque wrench by your authorized
dealer or service station.
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to
ensure that all lug nuts are properly seated against the wheel.
CAUTION!
Do not attempt to raise the vehicle by jacking on locations other than
those indicated in the Jacking Instructions for this vehicle.
WARNING!
• 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 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.
• Carefully follow these tire changing warnings to help prevent
personal injury or damage to your vehicle:
• Alwayspark 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.
• 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.

WARNING!(Continued)
• To assure that spare tires, flat or inflated, are securely stowed,
spares must be stowed with the valve stem facing the ground.
• 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.
• To avoid the risk of forcing the vehicle off the jack, do not tighten
the wheel nuts fully until the vehicle has been lowered.
• A loose tire or jack, thrown forward in a collision or hard stop, could
endanger the occupants of the vehicle. Always stow thejack 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 a set 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 right rear of the engine
compartment.
• Set the parking brake, shift the automatic transmission into PARK and
turn 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 (+) post
of the discharged vehicle.

SHIFT LEVER OVERRIDE
• If a malfunction occurs and the
shift 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.
TOWING A DISABLED VEHICLE
• The manufacturer requires towing your vehicle with all four wheelsOFF
the ground using a flatbed.
CAUTION!
Towing this vehicle using any other method could result in extensive
damage to the transfer case and/or transmission.

EVENT DATA RECORDER (EDR)
• This vehicle is equipped with an event data recorder (EDR). The main
purpose of an EDR is to record, in certain crash or near crash-like
situations, such as an air bag deployment or hitting a road obstacle, data
that will assist in understanding how a vehicle’s systems performed. The
EDR is designed to record data related to vehicle dynamics and safety
systems for a short period of time, typically 30 seconds or less. The EDR
in this vehicle is designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were
buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or
brake pedal; and,
• How fast the vehicle was traveling.
• These data can help provide a better understanding of the circumstances
in which crashes and injuries occur.
NOTE:EDR data are recorded by your vehicle only if a non-trivial crash
situation occurs; no data are recorded by the EDR under normal driving
conditions and no personal data (e.g. name, gender, age, and crash location)
are recorded. However, other parties, such as law enforcement, could
combine the EDR data with the type of personally identifying data routinely
acquired during a crash investigation.
• To read data recorded by an EDR, special equipment is required, and
access to the vehicle or the EDR is needed. In addition to the vehicle
manufacturer, other parties such as law enforcement, that have the
special equipment, can read the information if they have access to the
vehicle or the EDR.

WARNING!
• Overloading of your tires is dangerous. Overloading can cause tire
failure, affect vehicle handling, and increase your stopping distance.
Use tires of the recommended load capacity for your vehicle. Never
overload them.
• Improperly inflated tires are dangerous and can cause collisions.
Under-inflation is the leading cause of tire failure and may result in
severe cracking, component separation, or “blow out”. Over-
inflation reduces a tire’s ability to cushion shock. Objects on the
road and chuck holes can cause damage that results in tire failure.
Unequal tire pressures can cause steering problems. You could lose
control of your vehicle. Over-inflated or under-inflated tires can
affect vehicle handling and can fail suddenly, resulting in loss of
vehicle control.
WHEEL AND WHEEL TRIM CARE
• All wheels and wheel trim, especially aluminum and chrome plated
wheels, should be cleaned regularly with a mild soap and water to
prevent corrosion.
• To remove heavy soil and/or excessive brake dust, use MOPAR® Wheel
Cleaner or equivalent or select a non-abrasive, non-acidic cleaner.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush, or metal
polishes. Do not use oven cleaner. These products may damage the
wheel's protective finish. Avoid automatic car washes that use acidic
solutions or harsh brushes that may damage the wheel's protective
finish. Only MOPAR® Wheel Cleaner or equivalent is recommended.
