Airbag Systems
Your vehicle has six airbags:
A frontal airbag for the driver and another frontal
airbag for the right front passenger,
a seat mounted side impact airbag for the driver
and another for the right front passenger,
a roof-mounted side impact airbag for the driver
and passenger directly behind the driver, and
a roof-mounted side impact airbag for the right front
passenger and the person seated directly behind
that passenger.
Frontal airbags are designed to help reduce the risk of
injury from the force of an inating airbag. But these
airbags must inate very quickly to do their job
and comply with federal regulations.Here are the most important things to know about the
airbag systems:
{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. Airbags are “supplemental
restraints” to the safety belts. All airbags are
designed to work with safety belts but do not
replace them.
CAUTION: (Continued)
1-48

CAUTION: (Continued)
Frontal airbags for the driver and right front
passenger are designed to deploy only in
moderate to severe frontal and near frontal
crashes. They are not designed to inate in
rollover, rear or low-speed frontal crashes, or
in many side crashes. And, for some
unrestrained occupants, frontal airbags may
provide less protection in frontal crashes than
more forceful airbags have provided in the
past. The seat-mounted side impact airbags
and roof-mounted side impact airbags are
designed to inate only in moderate to severe
crashes where something hits the side of your
vehicle. They are not designed to inate in
frontal, in rollover or in rear crashes. Everyone
in your vehicle should wear a safety belt
properly — whether or not there is an airbag
for that person.
{CAUTION:
Both frontal and side impact airbags inate
with great force, faster than the blink of an
eye. If you are too close to an inating airbag,
as you would be if you were leaning forward,
it could seriously injure you. Safety belts help
keep you in position for airbag ination before
and during a crash. Always wear your safety
belt even with frontal airbags. The driver
should sit as far back as possible while still
maintaining control of the vehicle. Occupants
should not lean on or sleep against the door.
1-49

The side impact airbag for the right front passenger and
the person seated directly behind that passenger is in
the ceiling above the side windows.
{CAUTION:
If something is between an occupant and an
airbag, the bag 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. And, because your vehicle
has side impact airbags, never secure anything
to the roof of your vehicle by routing the rope
or tiedown through any door or window
opening. If you do, the path of an inating side
impact airbag will be blocked. The path of an
inating airbag must be kept clear.
1-53

In many crashes severe enough to inate the airbag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for
your airbag system. If you do not get them,
the airbag system will not be there to help protect
you in another crash. A new system will include
airbag modules and possibly other parts. The
service manual for your vehicle covers the need to
replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after
a crash. SeeVehicle Data Collection and Event
Data Recorders on page 7-9.
Let only qualied technicians work on your airbag
system. Improper service can mean that an
airbag system will not work properly. See your
dealer for service.Notice:If you damage the covering for the driver’s
or the right front passenger’s airbag, or the airbag
covering on the driver’s and right front passenger’s
seatback, or the side impact airbag covering on
the ceiling near the side windows, the bag may not
work properly. You may have to replace the
airbag module in the steering wheel, both the airbag
module and the instrument panel for the right
front passenger’s airbag, the airbag module and
seatback for the driver’s and right front passenger’s
seat-mounted side impact airbags, or side impact
airbag module and ceiling covering for the
roof-mounted side impact airbag. Do not open or
break the airbag coverings.

Servicing Your
Airbag-Equipped Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer and the service manual
have information about servicing your vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information on page 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are to close to an
airbag when it inates. Avoid wires wrapped
with yellow tape, yellow coverings or yellow
connectors. They are probably part of the
airbag systems. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
The airbag system does not need regular maintenance.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:If I add a luggage carrier or sunroof to the roof
of my vehicle, will it keep the roof-mounted side
impact airbags from working properly?
A:As long as the luggage carrier or sunroof is
properly installed so that the vehicle’s basic
structure is not changed, it is not likely to keep the
roof-mounted side impact airbags from working
properly in a crash.

3. Insert a narrow, pointed object into the hole in the
steering column cover and press the spring.
4. Then, turn the ignition switch to OFF and remove
the key.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned
from ON to OFF:
Radio
Power Windows
Audio Steering Wheel Controls (if programmed)
Sunroof (Option)
Power to these accessories stops after 10 minutes or if
a door is opened. If you want power for another
10 minutes, close all the doors and turn the ignition key
to ON and then back to OFF.
Starting Your Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
