front fascia/bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and then cycle
the ignition. If the message continues to appear
see an authorized dealer.
If the "PARKSENSE UNAVAILABLE SERVICE
REQUIRED" message appears in the instrument
cluster display, see an authorized dealer.
PARKSENSE PARK ASSIST FAILURE
I
NDICATIONS
A malfunction of the ParkSense Park Assist
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 59.
The sensors and wiring are tested continuously
when the ignition is in the ON/RUN position.
Failures are indicated immediately if they occur
when the system is on.
Even if the system is able to identify that a specific
sensor is in failure condition, the instrument
cluster display shall indicate that the ParkSense
Park Assist system is unavailable, without
reference to the sensor in failure condition. If even
a single sensor fails, the entire system must be
disabled. The system is turned off automatically.
CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.

SAGE PRECAUTIONS
NOTE:
Ensure that the front and rear fascia/bumper
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.
Construction equipment, large trucks, and other
vibrations could affect the performance of
ParkSense.
When you turn ParkSense off, the instrument
cluster display will read “PARKSENSE OFF.”
Furthermore, once you turn ParkSense off, it
remains off until you turn it on again, even if you
cycle the ignition key.
ParkSense, when on, will reduce the volume of
the radio when it is sounding a tone.

Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The sensors
must not be covered with ice, snow, slush, mud,
dirt or debris. Failure to do so can result in the
system not working properly. The ParkSense system might not detect an obstacle behind or in
front of the fascia/bumper, or it could provide a
false indication that an obstacle is behind or in
front of the fascia/bumper.

Use the ParkSense switch to turn the ParkSense
system off if objects such as bicycle carriers,
etc. are placed within 12 inches (30 cm) from
the rear fascia/bumper. Failure to do so can
result in the system misinterpreting a close
object as a sensor problem, causing the
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to be displayed in
the instrument cluster display.
NOTE:If any objects are attached to the bumper within a
6.5 ft (2 m) field of view, they will interfere and
cause false alerts and possibly blockage.
There may be a delay in the object detection
rate if the object is moving.
The operation of the rear sensors is automati
-
cally deactivated when the trailer's electric plug
is inserted in the vehicle's tow hook socket,
while the front sensors stay active and can
provide acoustic and visual warnings. The rear
sensors are automatically reactivated when the
trailer's cable plug is removed.

Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer
size, stoplights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness. The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.
NOTE:
Disconnect trailer wiring connector from the
vehicle before launching a boat (or any other
device plugged into vehicle’s electrical connect)
into water.

Be sure to reconnect after clear from water area.

Four-Pin Connector Seven-Pin Connector

TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away from
heavy traffic.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do
this could lead to accelerated brake lining wear,
higher brake pedal effort, and longer stopping
distances.

SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
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.

SAFETY165
NOTE:Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events
Side Air Bags and seat belt pretensioners are
designed to activate in certain rollover events.
The Occupant Restraint Controller (ORC)
determines whether deployment in a particular
rollover event is appropriate, based on the severity
and type of collision. Vehicle damage by itself is not
a good indicator of whether or not Side Air Bags
and seat belt pretensioners should have deployed.
The Side Air Bags and seat belt pretensioners will
not deploy in all rollover events. The rollover
sensing system determines if a rollover event
may be in progress and whether deployment is
appropriate. In the event the vehicle experiences a
rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy
the side air bags and seat belt pretensioners on
both sides of the vehicle.
The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through
side windows in certain rollover or side impact
events.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.

Seat belts (and child restraints where appropriate)
are necessary for your protection in all collisions.
They also help keep you in position, away from an
inflating Side Air Bag. To get the best protection
from the Side Air Bags, occupants must wear their
seat belts properly and sit upright with their backs
against the seats. Children must be properly
restrained in a child restraint or booster seat that
is appropriate for the size of the child.

WARNING!
Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the
center of the seat.
Being too close to the Side Air Bags during
deployment could cause you to be severely
injured or killed.
Relying on the Side Air Bags alone could lead
to more severe injuries in a collision. The Side
Air Bags work with your seat belt to restrain
you properly. In some collisions, Side Air Bags
won’t deploy at all. Always wear your seat belt
even though you have Side Air Bags.

event push the “A” Button located underneath the
instrument panel on the passenger side.
Fuel Cut Off Switch

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
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 accessories may
be used. If it is necessary to modify the air bag
system for persons with disabilities, contact an
authorized dealer.
