PARKSENSE PARK ASSIST FAILURE
I
NDICATIONS
A malfunction of the ParkSense sensors
or system is indicated, during REVERSE
gear engagement, by the instrument
panel warning icon.
The warning icon is illuminated and a message is
displayed in the instrument cluster display
(if equipped) Ú page 65.
The sensors and wiring are tested continuously
when the ignition is in the ON/RUN position.

SUPPLEMENTAL RESTRAINT
S
YSTEMS (S RS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.

The air bag system must be ready to protect you in a
collision. The Occupant Restraint Controller (ORC)
monitors the internal circuits and interconnecting
wiring associated with the electrical Air Bag System
Components. Your vehicle may be equipped with the
following Air Bag System Components:

Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the AVV (START) or
MAR (ACC/ON/RUN) position. If the ignition switch
is in the STOP (OFF/LOCK) position the air bag
system is not on and the air bags will not inflate.
The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
in the MAR (ACC/ON/RUN) position. After the
self-check, the Air Bag Warning Light will turn off.
If the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system
is designed to be maintenance free, if any of the following occurs, have an authorized dealer
service the air bag system immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the igni
-
tion switch is first in the MAR (ACC/ON/RUN)
position.
The Air Bag Warning Light remains on after the
four to eight-second interval.
The Air Bag Warning Light comes on intermit -
tently or remains on while driving.
NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be disabled.
In this condition the air bags may not be ready to
inflate for your protection. Have an authorized
dealer service the air bag system immediately.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have the
air bag system to protect you in a collision. If the
light does not come on as a bulb check when the
ignition is first turned on, stays on after you start
the vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag system
immediately.

SAFETY183
Air Bag System Components
NOTE:The Occupant Restraint Controller (ORC) monitors
the internal circuits and interconnecting wiring
associated with electrical Air Bag System Compo -
nents listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:Front and/or side air bags will not deploy in all colli -
sions. This does not mean something is wrong with
the air bag system. If you do have a collision which deploys the air
bags, any or all of the following may occur:

The air bag material may sometimes cause abra
-
sions and/or skin reddening to the occupants as
the air bags deploy and unfold. The abrasions are
similar to friction rope burns or those you might get
sliding along a carpet or gymnasium floor. They are
not caused by contact with chemicals. They are not
permanent and normally heal quickly. However, if
you haven’t healed significantly within a few days,
or if you have any blistering, see your doctor
immediately.

As the air bags deflate, you may see some
smoke-like particles. The particles are a normal
by-product of the process that generates the
non-toxic gas used for air bag inflation. These
airborne particles may irritate the skin, eyes,
nose, or throat. If you have skin or eye irritation,
rinse the area with cool water. For nose or throat
irritation, move to fresh air. If the irritation
continues, see your doctor. If these particles
settle on your clothing, follow the garment
manufacturer’s instructions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another collision,
the air bags will not be in place to protect you.
NOTE:

Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.

After any collision, the vehicle should be taken
to an authorized dealer immediately.
Fuel Cut Off Switch
Your vehicle is equipped with a Fuel Cut Off switch.
In the event of an accident, if the communication
network remains intact, and the power remains
intact, depending on the nature of the event, the
Fuel Cut Off Switch may perform the following
functions:
Cut off fuel to the engine and turn off the
engine.
Flash hazard lights as long as the battery has
power or until the hazard light button is pressed.
The hazard lights can be deactivated by
pressing the hazard light button.
WARNING!

Deployed air bags and seat belt pretensioners
cannot protect you in another collision. Have the air
bags, seat belt pretensioners, and the seat belt
retractor assemblies replaced by an authorized
dealer immediately. Also, have the Occupant
Restraint Controller System serviced as well.

Turn on the interior lights, which remain on as
long as the battery has power.
Unlock the power door locks.
NOTE:After an accident, remember to cycle the ignition
to the STOP (OFF/LOCK) position and remove the
key from the ignition switch to avoid draining the
battery. Carefully check the vehicle for fuel leaks in
the engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.
If there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the Fuel Cut Off Switch by following
the procedure described below. If you have any
doubt, contact an authorized dealer.
Fuel Cut Off Switch Reset Procedure
In order to reset the Fuel Cut Off Switch after an
event push the “A” Button located underneath the
front passenger side instrument panel.
Fuel Cut Off Switch

Maintaining Your Air Bag System
WARNING!
If, after an accident, you smell fuel or see leaks
from the fuel system, do not reset the Fuel Cut
Off Switch to avoid the risk of fire. Before
resetting the Fuel Cut Off Switch, carefully check
for fuel leaks or damage to the vehicle electrical
devices (e.g. headlights).
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 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.
