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 operating;
 Whether or not the driver and passenger safety belts
were buckled/fastened;
 How far (if at all) the driver was depressing the acceler -
ator 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 components 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 after -
market 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 accidentally or may
not function properly if modifications 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 accesso -
ries may be used. If it is necessary to modify the air
bag system for persons with disabilities, contact an
authorized dealer.

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.
 ONLY use the driver’s side floor mat on the driver’s
side floor area. To check for interference, 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 interferes 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.
WARNING!
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 acceler -
ator, brake, or clutch pedals and could cause a loss
of vehicle control.
 NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
 If the vehicle carpet has been removed and
re-installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
 It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the lug nut/bolt torque for tightness. Check the
tires (including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel or brake fluid leaks are
suspected, the cause should be located and corrected
immediately.
EXHAUST GAS
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system. Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have an authorized dealer inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO), follow
these safety tips:

Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
 If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
 If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
 Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi -
tions repaired promptly. Until repaired, drive with all
side windows fully open.
