Maintaining Your Air Bag System 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
WARNING!
Modifications to any part of the air bag system

It is dangerous to try to repair any part of the
air bag system yourself. Be sure to tell anyone
who works on your vehicle that it has an air
bag system.
Do not attempt to modify any part of your air
bag system. The air bag may inflate acciden -
tally or may not function properly if modifica -
tions are made. Take your vehicle to an
authorized dealer for any air bag system
service. If your seat, including your trim cover
and cushion, needs to be serviced in any way
(including removal or loosening/tightening of
seat attachment bolts), take the vehicle to an
authorized dealer. Only manufacturer
approved seat accessories may be used. If it is
necessary to modify the air bag system for
persons with disabilities, contact an autho -
rized dealer.

IN CASE OF EMERGENCY255
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 under the
passenger's front seat. There are remote terminals
located under the hood to assist in jump starting.

Under Hood Jump Starting Location Jump Starting Remote Posts

NOTE:Be sure that the disconnected cable ends do not
touch each other, or either vehicle, until properly
connected for jump starting.
See below steps to prepare for jump starting:

1. Apply the parking brake, shift the automatic
transmission into PARK (P) and turn the
ignition OFF.

2. Turn off the heater, radio, and all electrical accessories.
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.

262IN CASE OF EMERGENCY
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/bumpers 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, not the ACC mode.
If the vehicle's battery is discharged, instructions
on shifting the automatic transmission out of PARK
(P) in order to move the vehicle can be found on
Ú page 258.
REAR WHEEL DRIVE MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be towed
(with rear wheels on the ground) under the
following conditions:
The transmission must be in NEUTRAL (N).
For instructions on shifting the transmission to
NEUTRAL (N) when the engine is off
Ú page 258.
The towing speed must not exceed
30 mph (48 km/h).
The towing distance must not exceed
30 miles (48 km). If the transmission is not operable, or the vehicle
must be towed faster than 30 mph (48 km/h) or
farther than 30 miles (48 km), tow with the rear
wheels
OFF the ground. Acceptable methods are to
tow the vehicle on a flatbed, or with the front
wheels raised and the rear wheels on a towing
dolly, or (when using a suitable steering wheel
stabilizer to hold the front wheels in the straight
position) with the rear wheels raised and the front
wheels ON the ground.
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 suspension
components. Damage to your vehicle may
result from improper towing.
CAUTION!
Towing faster than 30 mph (48 km/h) or
farther than 30 miles (48 km) with rear
wheels on the ground can cause severe trans -
mission damage. Damage from improper
towing is not covered under the New Vehicle
Limited Warranty.

284SERVICING AND MAINTENANCE
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore, do
not add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
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 reservoir 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 contam
-
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An authorized
dealer has the proper tools to adjust the fluid
level accurately.
