Playing a CD (Single CD Player)
Insert a CD partway into the slot, label side up.
The player pulls it in and the CD should begin
playing.
If the ignition or radio is turned off with a CD in the
player, it stays in the player. When the ignition or
radio is turned on, the CD starts playing where it
stopped, if it was the last selected audio source.
When a CD is inserted, the CD symbol displays on
the CD. As each new track starts to play the track
number displays.
If playing a CD-R, the sound quality can be reduced
due to CD-R quality, the method of recording, the
quality of the music that has been recorded, and theway the CD-R has been handled. There can be an
increase in skipping, difficulty in nding tracks,
and/or difficulty in loading and ejecting. If these
problems occur, check the bottom surface of the
CD. If the surface of the CD is damaged, such as
cracked, broken, or scratched, the CD will not play
properly. If the surface of the CD is soiled, seeCare
of Your CDs on page 271for more information.
If there is no apparent damage, try a known
good CD.
Do not add any label to a CD, it could get caught in
the CD player. If a CD is recorded on a personal
computer and a description label is needed, try
labeling the top of the recorded CD with a
marking pen.
Notice:If a label is added to a CD, or more than
one CD is inserted into the slot at a time, or an
attempt is made to play scratched or damaged
CDs, the CD player could be damaged. While
using the CD player, use only CDs in good
condition without any label, load one CD at a
time, and keep the CD player and the loading
slot free of foreign materials, liquids, and
debris.
If an error displays, see “CD Messages” later in

XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy
foliage, bridges, garages, or tunnels may cause
the loss of XM™ signal for a period of time.
The radio might display NO XM SIGNAL to
indicate interference.
Cellular Phone Usage
Cellular phone usage could cause interference
with your vehicle’s radio. This interference
could occur when making or receiving phone calls,
charging the phone’s battery, or simply having
the phone on. This interference is an increased
level of static while listening to the radio. If static is
received while listening to the radio, unplug the
cellular phone and turn it off.
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
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.

Before changing lanes, check your mirrors. Then
use your turn signal.
Just before you leave the lane, glance quickly
over your shoulder to make sure there is not
another vehicle in your blind spot.
Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted.
Reduce your speed according to your
speedometer, not to your sense of motion. After
driving for any distance at higher speeds, you may
tend to think you are going slower than you
actually are.Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If
you must start when you are not fresh — such
as after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out. Of
course, you will nd experienced and able
service experts in GM dealerships all across North
America. They will be ready and willing to help
if you need it.
Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the lenses
clean?

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal
down while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the
chocks.
4. Stop and have someone pick up and store the
chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when
you’re pulling a trailer. SeeScheduled
Maintenance on page 471for more information.
Things that are especially important in trailer
operation are automatic transmission uid (don’t
over ll), engine oil, axle lubricant, drive belt,
cooling system and brake system. Each of these
is covered in this manual, and the Index will
help you nd them quickly. If you’re trailering, it’s
a good idea to review this information before
you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat
during severe operating conditions. SeeEngine
Overheating on page 372.
