252 SAFETY
(Continued)
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain side impact events.
Side Impacts
The Side Air Bags are designed to activate in certain side
impacts. The Occupant Restraint Controller (ORC) deter-
mines whether the deployment of the Side Air Bags in a
particular impact event is appropriate, based on the severity
and type of collision. The side impact sensors aid the ORC in
determining the appropriate response to impact events. The system is calibrated to deploy the Side Air Bags on the
impact side of the vehicle during impacts that require Side
Air Bag occupant protection. In side impacts, the Side Air
Bags deploy independently; a left side impact deploys the
left Side Air Bags only and a right-side impact deploys the
right Side Air Bags only. Vehicle damage by itself is not a
good indicator of whether or not Side Air Bags should have
deployed.
The Side Air Bags will not deploy in all side collisions,
including some collisions at certain angles, or some side
collisions that do not impact the area of the passenger
compartment. The Side Air Bags may deploy during angled
or offset frontal collisions where the front air bags deploy.
Side Air Bags are a supplement to the seat belt restraint
system. Side Air Bags deploy in less time than it takes to
blink your eyes.
WARNING!
• Do not mount equipment, or stack luggage or other cargo up high enough to block the deployment of the
SABICs. The trim covering above the side windows
where the SABIC and its deployment path are located
should remain free from any obstructions.
• In order for the SABICs to work as intended, do not install any accessory items in your vehicle which could
alter the roof. Do not add an aftermarket sunroof to
your vehicle. Do not add roof racks that require perma -
nent attachments (bolts or screws) for installation on
the vehicle roof. Do not drill into the roof of the vehicle
for any reason.
WARNING!
• Occupants, including children, who are up against or very close to Side Air Bags can be seriously injured or
killed. Occupants, including children, should never
lean on or sleep against the door, side windows, or area
where the side air bags inflate, even if they are in an
infant or child restraint.

Air Bag System Components
NOTE:
The Occupant Restraint Controller (ORC) monitors the
internal circuits and interconnecting wiring associated with
electrical Air Bag System Components 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
• Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners
• Seat Track Position SensorsIf 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 collisions.
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 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 gymna -
sium 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 imme -
diately.
• As the air bags deflate, you may see some smoke-like parti -
cles. 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

STARTING AND OPERATING 379
PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver. Refer to “ParkSense System Usage
Precautions” in this section for limitations of this system and
recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE. If ParkSense is enabled at this gear selector posi-
tion, the system will remain active until the vehicle speed is
increased to approximately 7 mph (11 km/h) or above.
When in REVERSE and above the system's operating speed,
a warning will appear within the instrument cluster display
indicating the vehicle speed is too fast. The system will
become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
ParkSense Sensors
The four ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is within
the sensors’ field of view.
The sensors can detect obstacles from approximately
18 inches (45 cm) up to 79 inches (200 cm) from the rear
fascia/bumper in the horizontal direction, depending on the
location, type and orientation of the obstacle.
NOTE:
If equipped as a dually, the ParkSense system has six rear
sensors to assist in detection around the dually flares.

STARTING AND OPERATING 385
Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with the ParkSense
switch.When the gear selector is moved to REVERSE and
the system is disabled, the instrument cluster
display will show the vehicle graphic with “Off”
over the arcs for as long as the vehicle is in REVERSE.
NOTE:
The ParkSense system will automatically disable when the
system detects that a trailer with trailer brakes has been
connected to the Integrated Trailer Brake Module. The
instrument cluster display will show an “Off” message over
the arcs if the ParkSense system is off, or a “Trailer” message
if the system is on, for as long as the vehicle is in REVERSE.
The ParkSense switch LED will be on when ParkSense is
disabled or defective. The ParkSense switch LED will be off
when the system is enabled.
If the ParkSense switch is pushed, and the system is disabled
or requires service, the ParkSense switch LED will blink
momentarily, and then the LED will be on.
Service The ParkSense Rear Park Assist System
During vehicle start up, when the Rear ParkSense System
has detected a faulted condition, the instrument cluster
display will show the "Rear ParkSense Unavailable Service
Required" or the "Rear ParkSense Unavailable Wipe Sensors"
message.
When the gear selector is moved into REVERSE, a vehicle
graphic will show in the instrument cluster display, along
with the display overlay “Rear ParkSense Unavailable Wipe
Sensors.” If the system needs service, the display overlay will
read “Rear ParkSense Unavailable Service Required” Under
this condition, ParkSense will not operate.
If "Rear ParkSense Unavailable Wipe Sensors" appears in the
instrument cluster display make sure the outer surface and
the underside of the rear 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 autho -
rized dealer.
If "Rear ParkSense Unavailable Service Required" appears in
the instrument cluster display, see an authorized dealer.

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.
ParkSense System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of snow, ice, mud, dirtand debris to keep the ParkSense system operating prop -
erly.
• Jackhammers, large trucks, and other vibrations could affect the performance of ParkSense.
• When you move the gear selector into REVERSE with ParkSense turned off, the instrument cluster display will
show "Off" on the vehicle graphic arcs for as long as the
vehicle is in REVERSE.
• 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 Park -Sense system might not detect an obstacle behind the
fascia/bumper, or it could provide a false indication that
an obstacle is behind the fascia/bumper.
• Ensure the ParkSense system is OFF if objects such as bicycle carriers, trailer hitches, etc., are placed within
18 inches (45 cm) of the rear fascia/bumper while driving
the vehicle. Failure to do so can result in the system misin -
terpreting a close obstacle as a sensor problem, causing the
"Rear ParkSense Unavailable Service Required" message
to appear in the instrument cluster display.
• On vehicles equipped with a tailgate, ParkSense should be disabled when the tailgate is in the lowered or open posi -
tion and the vehicle is in REVERSE. A lowered tailgate
could provide a false indication that an obstacle is behind
the vehicle.
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.

STARTING AND OPERATING 387
PARKSENSE FRONT AND REAR PARK ASSIST
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear, and/or
front fascia/bumper, and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
Refer to “ParkSense System Usage Precautions” in this
section for limitations of this system and recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of these
gear selector positions, the system will remain active until
the vehicle speed is increased to approximately 7 mph
(11 km/h) or above. A warning will appear in the instrument
cluster display when the vehicle is in REVERSE, indicating
the vehicle is above ParkSense operating speed. The system
will become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h).
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is discon -
nected 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 loudspeaker 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.
CAUTION!
• ParkSense is only a parking aid and it is unable to recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using Park -
Sense in order to be able to stop in time when an
obstacle is detected. It is recommended that the driver
looks over his/her shoulder when using ParkSense.
