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
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 oper
-
ating;
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.
WARNING!
Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo -
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.
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.

Defroster
Check operation by selecting the defrost mode and
place the blower control on high speed. You should
be able to feel the air directed against the
windshield. See an authorized dealer for service if
your defroster is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your vehicle.
Only use a floor mat that does not interfere with the
operation of the accelerator, brake or clutch
pedals. Only use a floor mat that is securely
attached using the floor mat fasteners so it cannot
slip out of position and interfere with the
accelerator, brake or clutch pedals or impair safe
operation of your vehicle in other ways.
WARNING!
An improperly attached, damaged, folded, or
stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to interfere
with the accelerator, brake, or clutch pedals and
cause a loss of vehicle control. To prevent
SERIOUS INJURY or DEATH:
 ALWAYS securely attach your floor
mat using the floor mat fasteners. DO
NOT install your floor mat upside down
or turn your floor mat over. Lightly pull
to confirm mat is secured using the floor mat
fasteners on a regular basis.
 ALWAYS REMOVE THE EXISTING
FLOOR MAT FROM THE VEHICLE
before installing any other floor mat.
NEVER install or stack an additional
floor mat on top of an existing floor mat.
ONLY install floor mats designed to fit your
vehicle. NEVER install a floor mat that cannot
be properly attached and secured to your
vehicle. If a floor mat needs to be replaced,
only use a FCA approved floor mat for the
specific make, model, and year of your
vehicle.
WARNING!
ONLY use the driver’s side floor mat on the
driver’s side floor area. To check for interfer -
ence, with the vehicle properly parked with the
engine off, fully depress the accelerator, the
brake, and the clutch pedal (if present) to
check for interference. If your floor mat inter -
feres with the operation of any pedal, or is not
secure to the floor, remove the floor mat from
the vehicle and place the floor mat in your
trunk.
ONLY use the passenger’s side floor mat on
the passenger’s side floor area.
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.

touch each other, or either vehicle, until properly
connected for jump starting.JUMP STARTING PROCEDURE
NOTE:Make sure at all times that unused ends of jumper
cables are not contacting each other or either
vehicle while making connections.
Remote Positive (+) Post
Remote Negative (-) Post
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and
personal injury could result.
WARNING!
Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is ON. You can be
injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could make
an inadvertent electrical contact. You could be
seriously 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.
WARNING!
Failure to follow this jump starting procedure
could result in personal injury or property
damage due to battery explosion.

IN CASE OF EMERGENCY323
In the event it is observed that the temperature
gauge is moving towards or close to the HOT (H)
position, you can reduce the potential for
overheating by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase the
engine idle speed while preventing vehicle
motion with the brakes.
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.
MANUAL PARK RELEASE
To move the vehicle in cases where the
transmission will not shift out of PARK (P) (such as
a depleted battery), a Manual Park Release is
available.
To activate the Manual Park Release, see the
following steps:

1. Apply firm pressure to the brake pedal while seated in the driver’s seat.

2. Apply the Electric Park Brake (EPB), if possible.
3. Using a flathead screwdriver or similar tool, remove the Manual Park Release access
cover, which is to the lower left of the steering
column.

Manual Park Release Access Cover
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads
“H,” pull over and stop the vehicle. Idle the
vehicle with the air conditioner turned off until
the pointer drops back into the normal range. If
the pointer remains on the “H” and you hear
continuous chimes, turn the engine off
immediately and call for service.
WARNING!
You should be seated in the driver’s seat with
your foot firmly placed on the brake pedal to
maintain control of the vehicle before activating
the Manual Park Release. If possible, you should
apply the parking brake. Activating the Manual
Park Release will allow your vehicle to roll away if
it is not secured or properly connected to a tow
vehicle. Activating the Manual Park Release on
an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.
