which allows the vehicle’s exterior perimeter lighting to
turn on each time the unlock button on the remote
keyless entry transmitter is pressed, can be enabled or
disabled. When EXT LIGHTS appears on the display,
press the reset button to scroll through the available
settings:
OFF:The exterior perimeter lighting will not turn on
when the unlock button on the remote keyless
entry transmitter is pressed.

Playing the Radio
O
(Power/Volume):Press this knob to turn the
system on and off.
Turn this knob clockwise to increase or counterclockwise
to decrease the volume.
Speed Compensated Volume (SCV):The radio is also
equipped with Speed Compensated Volume (SCV).
When SCV is on, the radio volume automatically adjusts
to compensate for road and wind noise as you speed
up or slow down while driving. That way, the volume
level should sound about the same as you drive.
To activate SCV:
1. Set the radio volume to the desired level.
2. Press the MENU button to display the radio
setup menu.
3. Press the pushbutton under the AUTO VOLUM
label on the radio display.
4. Press the pushbutton under the desired Speed
Compensated Volume setting (OFF, Low, Med,
or High) to select the level of radio volume
compensation. The display will time out after
approximately 10 seconds. Each higher setting
allows for more radio volume compensation at faster
vehicle speeds.
Finding a Station
BAND:Press this button to switch between AM, FM, or
XM™ (if equipped). The display will show the selection.
f(Tune):Turn this knob to select radio stations.
©SEEK¨:Press the right or left SEEK arrow to go
to the next or to the previous station and stay there.
To scan stations, press and hold either SEEK arrow for
a few seconds until you hear a beep. The radio will
go to a station, play for a few seconds, then go on to the
next station. Press either SEEK arrow again to stop
scanning.
The radio will only seek and scan stations with a strong
signal that are in the selected band.
4(Information) (XM™ Satellite Radio Service, MP3,
and RDS Features):Press the information button
to display additional text information related to the
current FM-RDS or XM™ station, or MP3 song. A choice
of additional information such as: Channel, Song,
Artist, and CAT may appear. Continue pressing the
information button to highlight the desired label, or press
the pushbutton positioned under any one of the labels
and the information about that label will be displayed.
When information is not available, No Info will appear on
the display.

You will hear a beep and the level will be adjusted
to the middle position.
To quickly adjust all tone and speaker controls to the
middle position, press the tune knob for more than
two seconds until you hear a beep.

Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. The CD player scans the bottom
surface of the disc. If the surface of a CD is damaged,
such as cracked, broken, or scratched, the CD will
not play properly or not at all. If the surface of a CD is
soiled, take a soft, lint free cloth or dampen a clean, soft
cloth in a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process starts
from the center to the edge.
Do not touch the bottom side of a CD while handling it;
this could damage the surface. Pick up CDs by
grasping the outer edges or the edge of the hole and
the outer edge.
Care of the CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the lens of the
CD optics with lubricants internal to the CD mechanism.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, straighten it out by hand. If the
mast is badly bent, replace it.
Check occasionally to make sure the mast is still
tightened to the fender. If tightening is required, tighten
by hand, then with a wrench one quarter turn.
XM™ Satellite Radio Antenna
System (Trunk Mounted)
Your vehicle may have the XM™ Satellite Radio
antenna that is located on the trunk of your vehicle.
Keep this antenna clear of snow and ice build up
for clear radio reception.

Braking
SeeBrake System Warning Light on page 3-27.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement
or gravel; the condition of the road, whether it is
wet, dry, or icy; tire tread; the condition of your brakes;
the weight of the vehicle; and the amount of brake
force applied.Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3.

Anti-Lock Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock
brakes, this warning light
on the instrument panel will
come on brie y when
you start your vehicle.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that
your brake pedal moves or pulses a little. This is normal.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
4-7

The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.
