64STARTING AND OPERATING
PARKSENSE REAR PARK ASSIST
F
AILURE INDICATIONS
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 on the instrument cluster display (if
equipped) Ú page 44.
The sensors and wiring are tested continuously
when the ignition is in the MAR (ACC/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
system is unavailable, without reference to the
sensor in failure condition. If even a single sensor
fails, the entire system will be disabled. The system
is turned off automatically.
CLEANING THE PARKSENSE REAR PARK
A
SSIST SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. In washing stations, clean sensors quickly
while keeping the vapor jet/high pressure washing
nozzles at least 4 inches (10 cm) from the sensors. Do not scratch or poke the sensors. Otherwise, you
could damage the sensors.
PARKSENSE REAR PARK ASSIST
S
YSTEM USAGE PRECAUTIONS
NOTE:
Ensure that the outer surface and the underside
of the rear fascia/bumper is clean and clear of
snow, ice, mud, dirt or other obstruction to keep
the ParkSense Rear Park Assist system oper -
ating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of the
ParkSense system.

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 the
fascia/bumper, or it could provide a false indica -
tion that an obstacle is behind the fascia/bumper.

Objects such as bicycle carriers, etc., must not
be placed within 12 inches (30 cm) from the
rear fascia/bumper while driving the vehicle.
Failure to do so can result in the system misin -
terpreting a close object as a sensor problem,
causing a failure indication to be displayed in
the instrument cluster display.
WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and
must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.

Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
assembly be disconnected from the vehicle
when the vehicle is not used for towing.
Failure to do so can result in injury or damage
to vehicles or obstacles because the hitch
ball will be much closer to the obstacle than
the rear fascia when the vehicle sounds the
continuous tone. Also, the sensors could
detect the ball mount and hitch ball
assembly, depending on its size and shape,
giving a false indication that an obstacle is
behind the vehicle.

STARTING AND OPERATING73
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
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 once clear from water
area.

Four-Pin Connector

WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.
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.

How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and
allow it to retract completely to disengage the
Automatic Locking Mode and activate the vehicle
sensitive (emergency) locking mode.
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
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee 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.
WARNING!
The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR)
feature or any other seat belt function is not
working properly when checked according to
the procedures in the Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the seat
belt or children who are using booster seats.
The locked mode is only used to install
rear-facing or forward-facing child restraints
that have a harness for restraining the child.

SAFETY149
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
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee 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
abrasions and/or skin reddening to the occu
-
pants 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 perma-
nent 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.

SAFETY151
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.
This data can help provide a better understanding
of the circumstances in which crashes and injuries
occur.
NOTE:EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are
recorded by the EDR under normal driving condi -
tions and no personal data (e.g., name, gender,
age, and crash location) are recorded. However,
other parties, such as law enforcement, could
combine the EDR data with the type of personally
identifying data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special
equipment is required, and access to the vehicle or
the EDR is needed. In addition to the vehicle
manufacturer, other parties, such as law
enforcement, that have the special equipment,
can read the information if they have access to the
vehicle or the EDR.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.
