steering GMC ACADIA 2007 Owner's Manual

Airbag System
Your vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
A seat-mounted side impact airbag for the
driver.
A seat-mounted side impact airbag for the
right front passenger.
A roof-rail airbag for the driver, passenger
directly behind the driver, and the third
row outboard passenger position.
A roof-rail airbag for the right front passenger,
passenger directly behind the right front
passenger, and the third row outboard
passenger position.
All of the airbags in your vehicle will have the
word AIRBAG embossed in the trim or on
an attached label near the deployment opening.
For frontal airbags, the word AIRBAG will
appear on the middle part of the steering wheel
for the driver and on the instrument panel for
the right front passenger.With seat-mounted side impact airbags, the word
AIRBAG will appear on the side of the seatback
closest to the door.
With roof-rail airbags, the word AIRBAG will
appear along the headliner or trim.
Airbags are designed to supplement the protection
provided by safety belts. Even though today’s
airbags are also designed to help reduce the risk
of injury from the force of an inating bag, all
airbags must inate very quickly to do their job.
Here are the most important things to know about
the airbag system:
{CAUTION:
You can be severely injured or killed in a
crash if you are not wearing your safety
belt — even if you have airbags. Wearing
your safety belt during a crash helps
reduce your chance of hitting things
inside the vehicle or being ejected from it.
CAUTION: (Continued)
76

The system checks the airbag electrical system for
malfunctions. The light tells you if there is an
electrical problem. SeeAirbag Readiness Light on
page 217for more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.The right front passenger’s frontal airbag is in the
instrument panel on the passenger’s side.
79

{CAUTION:
If something is between an occupant and
an airbag, the airbag might not inate
properly or it might force the object into
that person causing severe injury or even
death. The path of an inating airbag must
be kept clear. Do not put anything
between an occupant and an airbag, and
do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering.
Do not use seat accessories that block
the ination path of a seat-mounted side
impact airbag.
If your vehicle has roof-rail airbags, never
secure anything to the roof of your
vehicle by routing the rope or tie down
through any door or window opening. If
you do, the path of an inating roof-rail
airbag will be blocked.
When Should an Airbag Inate?
Frontal airbags are designed to inate in moderate
to severe frontal or near-frontal crashes to help
reduce the potential for severe injuries mainly
to the driver’s or right front passenger’s head and
chest. However, they are only designed to
inate if the impact exceeds a predetermined
deployment threshold. Deployment thresholds are
used to predict how severe a crash is likely to
be in time for the airbags to inate and help
restrain the occupants.
Whether your frontal airbags will or should deploy
is not based on how fast your vehicle is traveling.
It depends largely on what you hit, the direction
of the impact, and how quickly your vehicle
slows down.
Frontal airbags may inate at different crash
speeds. For example:
If the vehicle hits a stationary object, the
airbags could inate at a different crash speed
than if the vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash
speed than if the vehicle hits an object that
does not deform.
81

What Makes an Airbag Inate?
In a deployment event, the sensing system sends
an electrical signal triggering a release of gas
from the inator. Gas from the inator lls
the airbag causing the bag to break out of the
cover and deploy. The inator, the airbag,
and related hardware are all part of the airbag
module.
Frontal airbag modules are located inside the
steering wheel and instrument panel. For vehicles
with seat-mounted side impact airbags, there
are airbag modules in the side of the front
seatbacks closest to the door. For vehicles with
roof-rail airbags, there are airbag modules in
the ceiling of the vehicle, near the side windows
that have occupant seating positions.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact the
steering wheel or the instrument panel. In
moderate to severe side collisions, even belted
occupants can contact the inside of the vehicle.Airbags supplement the protection provided by
safety belts.
Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body,
stopping the occupant more gradually.
Seat-mounted side impact and roof-rail airbags
distribute the force of the impact more evenly over
the occupant’s upper body.
Rollover capable roof-rail airbags are designed to
help contain the head and chest of occupants
in the outboard seating positions in the rst,
second, and third rows. The rollover capable
roof-rail airbags are designed to help reduce the
risk of full or partial ejection in rollover events,
although no system can prevent all such ejections.
But airbags would not help in many types of
collisions, primarily because the occupant’s motion
is not toward those airbags. SeeWhen Should
an Airbag Inflate? on page 81for more information.
Airbags should never be regarded as anything
more than a supplement to safety belts.
83

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the
exterior of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, height,
front end or side sheet metal, they may keep
the airbag system from working properly.
Also, the airbag system may not work properly
if you relocate any of the airbag sensors. If
you have any questions about this, you should
contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. See Customer
Satisfaction Procedure.
If your vehicle has rollover roof-rail airbags,
seeDifferent Size Tires and Wheels on
page 452for additional important information.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the
front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel,
instrument panel, roof-rail airbag modules,
ceiling headliner, and pillar garnish trim, side
impact sensors, rollover sensor module,
or airbag wiring can affect the operation of the
airbag system. If you have questions, call
Customer Assistance. The phone numbers
and addresses for Customer Assistance are in
Step Two of the Customer Satisfaction
Procedure in this manual. SeeCustomer
Satisfaction Procedure on page 518.
Your dealer/retailer and the service manual have
information about the location of the airbag
sensors, sensing and diagnostic module and
airbag wiring.

Other Warning Devices
If you carry reective triangles, you can set them
up at the side of the road about 300 feet (100 m)
behind your vehicle.
Horn
Press near or on the horn symbols on the steering
wheel pad to sound the horn.
Tilt and Telescopic Steering Wheel
A tilt and telescope wheel lets you adjust the
steering wheel before you drive. The steering
wheel can be raised to the highest level to give
your legs more room when you enter and exit the
vehicle.
The lever that lets you tilt and telescope the
steering wheel is located on the left side of the
steering column.To tilt and telescope the steering wheel, pull down
the lever. Then move the steering wheel up or
down or backward or forward into a comfortable
position. Pull the lever up to lock the steering
wheel in place.
