Restraint System Check
Checking the Restraint Systems
Now and then, make sure the safety belt reminder
light and all your belts, buckles, latch plates,
retractors and anchorages are working properly.
Look for any other loose or damaged safety
belt system parts. If you see anything that might
keep a safety belt system from doing its job, have
it repaired. Keep safety belts clean and dry.
SeeCare of Safety Belts on page 531for more
information.
Torn or frayed safety belts may not protect you in
a crash. They can rip apart under impact forces.
If a belt is torn or frayed, get a new one right away.Also look for any opened or broken airbag
covers, and have them repaired or replaced.
(The airbag system does not need regular
maintenance.)
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 roof-mounted rollover airbags (if equipped.)
Do not open or break the airbag coverings.

Section 2 Features and Controls
110

Retained Accessory Power (RAP)
Your vehicle has a Retained Accessory Power
(RAP) feature which will allow certain features on
your vehicle to continue to work up to 10 minutes
after the ignition key is turned to LOCK.
The radio, power windows, and if the vehicle
has these features, the sunroof and OnStar
®
System, will work when the ignition key is in
RUN or ACCESSORY. Once the key is turned
from RUN to LOCK, these features will continue
to work for up to 10 minutes or until a door is
opened.
Starting the Engine
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.1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will go
down as your engine gets warm.
Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects the electrical
system. If the ignition key is turned to the
START position, and then released when the
engine begins cranking, the engine will continue
cranking until the vehicle starts or until it
exceeds the maximum cranking time allowed,
approximately 15 seconds to prevent cranking
motor damage. To prevent gear damage, this
system also prevents cranking if the engine is
already running. The engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can
overheat and damage the cranking motor and
drain the battery. Waiting about 15 seconds
between each try, to allow the cranking motor to
cool down, will prevent damage due to
overheating.

Center Console Storage Area
Your vehicle may have a console compartment
with cupholders between the bucket seats.
To open it, press the button and lift the console
lid open.
The rear of the console has a cupholder that
swings down for the rear seat passenger to use.
Luggage Carrier
If you have the luggage carrier, you can load
things on top of your vehicle.
The luggage carrier has siderails attached to the
roof and crossrails, if equipped, which can be
moved back and forth to help secure cargo. Tie the
load to the siderails or siderail supports.
Notice:Loading cargo on the luggage carrier
that weighs more than 200 lbs (91 kg) or
hangs over the rear or sides of the vehicle
may damage your vehicle. Load cargo so that
it rests as far forward as possible and
against the side rails, making sure to fasten it
securely.Do not exceed the maximum vehicle capacity
when loading your vehicle. For more information
on vehicle capacity and loading, seeLoading Your
Vehicle on page 390.
To prevent damage or loss of cargo as you are
leaving, check now and then to make sure
the luggage and cargo are still securely fastened.
Be sure the cargo is properly loaded.
If small heavy objects are placed on the roof,
place the load in the area over the rear wheels
(behind the rear side door on extended
models). If you need to, cut a piece of 3/8 inch
plywood to t inside the crossrails and siderails
to spread the load. If plywood is used, tie it to
the siderail supports.
Tie the load to the crossrails or the siderail
supports. Use the crossrails only to keep the
load from sliding. To move the crossrails, pull
out on the latch release handle at each end.
Slide the crossrail to the desired position
balancing the force side to side. Push the
release handle back into the latched position
and slide the crossrail back and forth slightly to
be sure the latch snaps securely into place.
175

If you need to carry long items, move the
crossrails as far apart as they will go. Tie the
load to the crossrails and the siderails or
siderail supports. Also tie the load to the
bumpers. Do not tie the load so tightly that the
crossrails or siderails are damaged.
After moving a crossrail, be sure it is securely
locked into the siderail.
Your vehicle has a Center High-Mounted Stoplamp
(CHMSL) located above the glass or above the
rear load doors.
If items are loaded on the roof of the vehicle, care
should be taken not to block or damage the
CHMSL unit.
Rear Storage Area
Your vehicle may have a storage compartment
located in the rear cargo area of the vehicle in the
driver’s side trim panel.
To open the utility compartment, turn the knobs
and swing the compartment door open. The
compartment door can be removed.
Rear Seat Armrest
Your vehicle may be equipped with a rear seat
armrest. Pull the loop at the top of the armrest
down to access the cupholders.
Cargo Cover
{CAUTION:
An improperly stored cargo cover could
be thrown about the vehicle during a
collision or sudden maneuver. You or
others could be injured. If you remove the
cover, always store it in the proper
storage location. When you put it back,
always be sure that it is securely
reattached.
If you have a cargo cover, you can use it to cover
items in the cargo area of your vehicle.

Care of the CD and DVD Player
The use of CD lens cleaners for CDs is not
advised, due to the risk of contaminating the lens
of the CD optics with lubricants internal to the
CD mechanism.
Rear Side Window Antenna
Your AM-FM antenna is located in the passenger
rear side windows. Be sure that the inside
surfaces of the rear side windows are not
scratched and that the lines on the glass are not
damaged. If the inside surfaces are damaged, they
could interfere with radio reception.
Notice:Using a razor blade or sharp object to
clear the inside of the rear side windows
may affect radio reception or damage the rear
window defogger. Repairs would not be
covered by your warranty. Do not clear the
inside of the rear side windows 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 antenna due to metallic tinting materials
will not be covered by your warranty.Because this antenna is built into your rear side
window, there is a reduced risk of damage caused
by car washes and vandals.
If you choose to add an aftermarket 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
antennas or place the cellular telephone antenna
over the grid lines.
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.
Loading items onto the roof of your vehicle can
interfere with the performance of the XM™ system.
Make sure that the XM™ satellite antenna is not
obstructed.
