Airbag System
Your vehicle has a frontal airbag for the driver and
another frontal airbag for the right front passenger.
Your vehicle may also have roof mounted side impact
airbags. Roof mounted side impact airbags are available
for the driver and the passenger seated directly behind
the driver and for the right front passenger and the
passenger seated directly behind that passenger.
If your vehicle has side impact airbags, the words
AIR BAG will appear on the airbag covering on the
ceiling near the driver’s and right front passenger’s
window.
Frontal airbags are designed to help reduce the risk
of injury from the force of an inating frontal 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 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. Airbags are “supplemental restraints”
to the safety belts. All airbags are designed to
work with safety belts but do not replace them.
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 roof-mounted side impact airbags
are designed to inate only in moderate to
severe crashes where something hits the
CAUTION: (Continued)
1-48

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, if 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.
1-52

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 7-10.
Let only qualied technicians work on your airbag
system. Improper service can mean that your 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 side
impact airbag covering on the ceiling near the
side windows, the airbag 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, 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. You do not want the system to
inate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the airbag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-13.
{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 close
to an airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. 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.

Sunroof
If the vehicle has a sunroof, it includes a sliding glass
panel and a sunshade. The switch to control the sunroof
is located in the headliner. The switch works only
while the ignition is on or in ACC, or Retained Accessory
Power (RAP) is on. SeeRetained Accessory Power

Delayed Exit Lighting
For exiting the vehicle at night, the vehicle is equipped
with the delayed exit lighting feature. The interior
lamps will light for up to 25 seconds when the key is
removed from the ignition. After 25 seconds have
elapsed, the interior lamps will slowly fade. The lamps
will fade before the 25 seconds have elapsed if any
of the following are done:
The ignition is turned to RUN or ACC.
The doors are locked using the remote keyless
entry transmitter.
The doors are locked using the power door
lock switch.
When any door is opened, delayed exit lighting is
cancelled. The interior lamps will stay on while any door
is opened and will slowly fade out when all the doors
are closed. The interior lamps may stay on for up
to 25 seconds after all the doors have been closed if
they have not been locked.
To turn the delayed exit lighting feature off or on, see
“Personal Programming Mode Screen” underDIC
Controls and Displays (Base Level DIC) on page 3-49
orDIC Controls and Displays (Uplevel DIC with Trip
Computer) on page 3-57.
Front Reading Lamps
If the vehicle has a sunroof, there are reading lamps in
front of the sunroof switch located on the headliner.
These lamps will come on when the doors are opened.
Press the side of each reading lamp to turn them on
and off when the doors are closed.
Overhead Console Reading Lamps
The vehicle may have reading lamps on the overhead
console. These lamps will turn on when the doors
are opened. When the doors are closed, press the side
of each lamp to turn them on and off.
Rear Assist Handle Reading Lamps
If the vehicle has reading lamps on each rear assist
handle, press the side of each lamp to turn it on or off.

Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear window
antenna and/or the rear window defogger. Repairs
would not be covered by your warranty. Do not clear
the inside rear window with sharp objects.
Notice:Do not apply aftermarket glass tinting with
metallic lm. The metallic lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by your warranty.
Because this antenna is built into your rear window,
there is a reduced risk of damage caused by car washes
and vandals.
If you choose to add a cellular telephone to your
vehicle, and the antenna needs to be attached to the
glass, be sure that you do not damage the grid lines for
the AM-FM antenna. There is enough space between
the lines to attach a cellular telephone antenna
without interfering with radio reception.
Do not apply aftermarket glass tinting to the back glass.
The metallic lm in some tinting materials will interfere
with or distort the incoming radio reception. Care
must be taken when cleaning the rear window because
it breaks in the resistive material heating element
and will adversely affect radio and defogger
performance. See your dealer for details.XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on the roof
of your vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
The performance of the XM system may be affected if
the sunroof is open.
Chime Level Adjustment
The radio is the vehicle chime producer. To change the
volume level, press and hold pushbutton 6 with the
ignition on and the radio power off. The chime volume
level will change from the normal level to loud, and
LOUD will appear on the radio display. To change back
to the default or normal setting, press and hold
pushbutton 6 again. The chime level will change from
the loud level to normal, and NORMAL will appear
on the radio display. Each time the chime volume is
changed, three chimes will sound as an example of the
new volume selected. Removing the radio and not
replacing it with a factory radio or chime module will
disable vehicle chimes.
