14. Have the aluminum road wheel and tire repaired as
soon as possible, properly secure the spare tire with
the special wing nut torqued to 3.7 ft-lbs (5 N·m),
reinstall the jack and tool kit foam tray, and latch the
rear load floor cover.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped
end of the nut toward the wheel. Lightly tighten the
lug nuts.

WHAT TO DO IN EMERGENCIES 513

WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
3. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
4. Refer to Torque Specifications for proper lug nut
torque.
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.
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.
WARNING!
Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
514 WHAT TO DO IN EMERGENCIES

CAUTION!(Continued)
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Push and hold the lock button on the shift
lever. Then shift back and forth between DRIVE and
REVERSE while gently pressing the accelerator.
NOTE:Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for
more than two seconds, you must push the brake pedal
to engage DRIVE or REVERSE.Use the least amount of accelerator pedal pressure that
will maintain the rocking motion without spinning the
wheels or racing the engine.
NOTE:Push theESC Offswitch (if necessary), to place
the Electronic Stability Control (ESC) system inPartial
Offmode, before rocking the vehicle. Refer to “Elec-
tronic Brake Control” in “Starting And Operating” for
further information. Once the vehicle has been freed,
push theESC Offswitch again to restoreESC On
mode.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce

CAUTION!(Continued)
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated 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 vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
CAUTION!
•When “rocking” a stuck vehicle by shifting be-
tween DRIVE and REVERSE, 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 trans-
mission shifting occurring).
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully applying the
parking brake, before activating the Manual Park
(Continued)

NOTE:Be sure to replace the cover by snapping it back
in place.
TOWING A DISABLED VEHICLE
The manufacturer requires towing your vehicle with all
four wheels OFF the ground using a flatbed.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK
for loading onto a flatbed truck.
CAUTION!
•Towing this vehicle using any other method can
cause severe transmission and/or transfer case dam-
age.
•Damage from improper towing is not covered un-
der the New Vehicle Limited Warranty.
Stowed Position
524 WHAT TO DO IN EMERGENCIES

•If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
•If your vehicle is damaged due to a collision or similar
cause that destroys the paint and protective coating,
have your vehicle repaired as soon as possible. The
cost of such repairs is considered the responsibility of
the owner.
•If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure that such materials are well
packaged and sealed.
•If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
•Use MOPAR® Touch Up Paint on scratches as soon as
possible. Your authorized dealer has touch up paint to
match the color of your vehicle.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 pro-
tective finish. Only MOPAR® Wheel Cleaner or
equivalent is recommended.
570 MAINTAINING YOUR VEHICLE

NOTE:If your vehicle is equipped with Dark Vapor
Chrome wheels DO NOT USE wheel cleaners, abrasives
or polishing compounds. They will permanently damage
this finish and such damage is not covered by the New
Vehicle Limited Warranty. USE ONLY MILD SOAP AND
WATER WITH A SOFT CLOTH. Used on a regular basis
this is all that is required to maintain this finish.
Stain Repel Fabric Cleaning Procedure — If
Equipped
Stain Repel seats may be cleaned in the following man-
ner:

concrete. A tire marked C may have poor traction perfor-
mance.
WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
Temperature Grades
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat
and its ability to dissipate heat, when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance, which allpassenger vehicle tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the laboratory
test wheel, than the minimum required by law.
WARNING!
The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
