WARNING! (Continued)
serious injury, including death. Air bags need room
to inflate. Sit back, comfortably extending your arms
to reach the steering wheel or instrument panel.
• Never place a rear-facing child restraint in front of an
air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.
• Never install a rear-facing child restraint in the front
seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.
Driver And Passenger Front Air Bag Features
The driver and passenger front air bag system is designed
to inflate based on the severity and type of collision as
determined by the Occupant Restraint Controller (ORC),
which may receive information from the front impact
sensors (if equipped) or other system components.

SAFETY 113

WARNING!
•No objects should be placed over or near the air bag
on the instrument panel or steering wheel because
any such objects could cause harm if the vehicle is in
a collision severe enough to cause the air bag to
inflate.
• Do not put anything on or around the air bag covers
or attempt to open them manually. You may damage
the air bags and you could be injured because the air
bags may no longer be functional. The protective
covers for the air bag cushions are designed to open
only when the air bags are inflating.
• Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, air bags won’t deploy at all. Always wear
your seat belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide additional protec-
tion by supplementing the seat belts. Front air bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions. The front air bags will not deploy in all frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, truck underrides, and angle offset collisions.
On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away
from an inflating air bag.
When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper passen-
ger side of the instrument panel separate and fold out of
the way as the air bags inflate to their full size. The front air
bags fully inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate while helping
to restrain the driver and front passenger.
114 SAFETY

positioned in the area where the SABICs inflate. Children
are at an even greater risk of injury from a deploying air
bag.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain side impact events.
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 lo-
cated 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 permanent attachments (bolts or screws) for
installation on the vehicle roof. Do not drill into the
roof of the vehicle for any reason. 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 sever-
ity 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.
5
SAFETY 117

The Side Air Bags 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 of the Side Air Bags is appropriate,
the rollover sensing system will also deploy the 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 Components 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
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 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.

PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides an au-
dible indication of the distance between the rear fascia/
bumper and a detected obstacle when backing up, e.g.
during a parking maneuver. Refer to “ParkSense System
Usage Precautions” for limitations of this system and
recommendations.
The ParkSense Rear Park Assist is automatically activated
when the transmission is placed into REVERSE. As the
distance from an obstacle behind the vehicle decreases, the
audible alert becomes more frequent.
Interaction With Trailer Towing
The Rear Park Assist system is automatically deactivated
when a trailer is hitched to the vehicle. The system will be
automatically activated as soon as the trailer is removed.
ParkSense Rear Park Assist Sensors
The four ParkSense Rear Park Assist 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, in the horizontal direction, from approxi-
mately 12 inches (30 cm) up to 55 inches (140 cm) from the
center of the rear fascia/bumper and up to 24 inches (60cm) from the corners of the rear fascia/bumper, depending
on the location, type and orientation of the obstacle.
If several obstacles are detected, the ParkSense Rear Park
Assist system indicates the nearest obstacle.
The minimum height of a detectable obstacle corresponds
to the maximum height of an obstacle that would clear the
underside of the vehicle during the parking maneuver.
ParkSense Rear Park Assist Alerts
If an obstacle is behind the vehicle when REVERSE gear is
engaged, an audible alert is activated.
Rear Park Assist Sensors Location
154 STARTING AND OPERATING

The tones emitted by the loudspeaker inform the driver
that the vehicle is approaching an obstacle. The pauses
between the tones are directly proportional to the distance
from the obstacle. Pulses emitted in quick successionindicate the presence of a very close obstacle. A continuous
tone indicates that the obstacle is less than 12 inches (30
cm) away.

STARTING AND OPERATING 155

While audible signals are emitted, the audio system is not
muted.
The audible signal is turned off immediately if the distance
increases. The tone cycle remains constant if the distance
measured by the inner sensors is constant. If this condition
occurs for the external sensors, the signal is turned off after
three seconds (stopping warnings during maneuvers par-
allel to walls).
ParkSense Rear Park Assist Failure Indications
A malfunction of the ParkSense Rear 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). Refer to “Warning Lights And Mes-
sages” in “Getting To Know Your Instrument
Panel” for further information.
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 Rear 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 Rear Park Assist sensors with water, car wash
soap and a soft cloth. Do not use rough or hard cloths. In
washing stations, clean sensors quickly 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 System Usage
Precautions
NOTE:
•
Ensure that the outer surface and the underside of the
rear bumper is clean and clear of snow, ice, mud, dirt or
other obstruction to keep the Rear Park Assist system
operating properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of Rear Park Assist.
• Clean the Rear Park Assist sensors regularly, taking care
not to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
