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 your autho-
rized dealer.
Your vehicle may be equipped with the following 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
• Supplemental Side Air Bags
• Front and Side Impact Sensors — If Equipped
• Seat Belt Pretensioners
• Seat Belt Buckle Switch
Front Air Bags
This vehicle has front air bags for both the driver and front
passenger as a supplement to the seat belt restraint sys-
tems. The driver front air bag is mounted in the center of
the steering wheel. The passenger front air bag is mounted
in the instrument panel, above the glove compartment. The
words “SRS AIRBAG” or “AIRBAG” are embossed on the
air bag covers.

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 Advanced 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.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
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.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether the
driver or front passenger seat belt is buckled. The seat belt
buckle switch may adjust the inflation rate of the Ad-
vanced Front Air Bags.

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 right 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.

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 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 permanent attachments (bolts or screws) for
installation on the vehicle roof. Do not drill into the
roof of the vehicle for any reason.
The SABICs and SABs (“Side Air Bags”) are designed to
activate in certain side impacts. The Occupant Restraint
Controller (“ORC”) determines whether the deployment of the Side Air Bags in a particular impact event is appropri-
ate, 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 protec-
tion. In side impacts, the Side Air Bags deploy indepen-
dently; 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 Advanced
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. Occupants, including children, who are up
against or very close to Side Air Bags can be seriously
injured or killed. Occupants, including children, should

On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Electronic Speed Con-
trol.
WARNING!
Electronic Speed Control can be dangerous where the
system cannot maintain a constant speed. Your vehicle
could go too fast for the conditions, and you could lose
control and have an accident. Do not use Electronic
Speed Control in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
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 rec-
ommendations.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

(60 cm) from the corners of the rear fascia/bumper, de-
pending 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.
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 succession
indicate the presence of a very close obstacle. A continuous
tone indicates that the obstacle is less than 12 inches
(30 cm) away.
