196IN CASE OF EMERGENCY

Rear Lifting Point
Rear Jacking Location

NOTE:
The front jacking location is located behind the
front tire and in front of the driver/passenger
door. 3. Place the wrench handle and lug bolt
adapter on the jack screw and turn
clockwise until the jack head is properly
engaged in the described location. Do not
raise the vehicle until you are sure the jack
is securely engaged.
4. Raise the vehicle by turning the jack screw clockwise, using the wrench handle and lug
bolt adapter. Raise the vehicle only until the
tire just clears the surface and enough
clearance is obtained to install the spare
tire. Minimum tire lift provides maximum
stability. 5. Remove the wheel lug bolts. For vehicles
with wheel covers, remove the cover from
the wheel by hand. Do not pry the wheel
cover off. Then pull the wheel off the hub.
6. Install the spare tire. Lightly tighten the wheel lug bolts.

Mounting Spare Tire

WARNING!
Being under a jacked-up vehicle is
dangerous. The vehicle could slip off the jack
and fall on you. You could be crushed. Never
get 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.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.

IN CASE OF EMERGENCY209
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
fascia/bumper or associated brackets. State
and local laws regarding vehicles under tow
must be observed. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode.
If the key fob is unavailable or the vehicle's
battery is discharged, for instructions on
shifting the automatic transmission out of
PARK (P) for towing Ú
page 207.
Towing Condition Wheels OFF The Ground
ALL Models
Flat Tow NONEIf transmission is operable:
• Transmission in NEUTRAL
• 25 mph (40 km/h) max speed
• 15 miles (24 km) max distance
Wheel Lift Or Dolly Tow Rear
Front OK
Flatbed ALL BEST METHOD
CAUTION!
Do not use sling type equipment when
towing. Vehicle damage may occur.
When securing the vehicle to a flat bed
truck, do not attach to front or rear suspen-
sion components. Damage to your vehicle
may result from improper towing.7

220SERVICING AND MAINTENANCE
Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a
hydrofluorocarbon (HFC) that is an
ozone-saving product. However, FCA
recommends that air conditioning service be
performed by authorized dealer or other service
facilities using recovery and recycling
equipment.
NOTE:
Use only FCA approved A/C system PAG
compressor oil and refrigerants.
Cabin Air Filter (A/C Air Filter)
Refer to the Maintenance Plan in this chapter
for the proper maintenance intervals
Úpage 212. The cabin air filter is located in the fresh air inlet
in the engine compartment. Perform the
following procedure to replace the filter:

1. Remove the two screws that secure the
filter retainer to the fresh air inlet, and
remove the filter retainer.

Accessing Air Filter

2. Remove and replace the cabin air filter from the filter retainer.
Removing Air Filter

3. Install the cabin air filter/filter retainer back into the fresh air inlet. When installing the
filter retainer make sure the retainer is fully
engaged.
4. Install the two screws back into the assembly to secure the filter retainer to the
fresh air inlet.
WARNING!
Do not remove the cabin air filter while the
vehicle is running, or while the ignition is in
the ACC or ON/RUN mode. With the cabin air
filter removed and the blower operating, the
blower can contact hands and may propel dirt
and debris into your eyes, resulting in
personal injury.

BRAKE SYSTEM
In order to ensure brake system performance,
all brake system components should be
inspected periodically Úpage 212.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood
service or immediately if the brake system
warning lamp indicates system failure. If
necessary, add fluid to bring level within the
designated marks on the side of the reservoir of
the brake master cylinder. Be sure to clean the
top of the master cylinder area before removing
cap. With disc brakes the fluid level can be
expected to fall as the brake linings wear. However, an unexpected drop in fluid level may
be caused by a leak and a system check should
be conducted Ú
page 268.
AUTOMATIC TRANSMISSION
Selection Of Lubricant

It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only the
manufacturer’s specified transmission fluid

Ú
page 270. It is important to maintain the

WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
WARNING!
Use only FCA's recommended brake fluid
Ú page 268. Using the wrong type of brake
fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder
reservoir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser -
voir cap secured at all times. Brake fluid in
a open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
