Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise
if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach only about
10 to 40 miles (1 6 to 65 km).
Tall buildings or hills can interfere with FM signals,
causing the sound
to come and go.
XMTM Satellite Radio Service
XMTM Satellite Radio gives you digital radio reception
from coast to coast. Just as with FM, tall buildings
or hills can interfere with Satellite radio signals, causing
the sound to come and go. Your radio may display
NO SIGNAL to indicate interference.
Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display
CLN to
indicate that you have used your tape player for
50 hours without resetting the tape clean timer.
If this
message appears on the display, your cassette
tape player needs to be cleaned. It
will still play tapes,
but you should clean it as soon as possible to
prevent damage
to your tapes and player. If you notice
a reduction in sound quality, try a known good
cassette
to see if the tape or the tape player is at fault.
If this other cassette has no improvement
in sound
quality, clean the tape player.
3-87

For best results, use a scrubbing action, non-abrasive
cleaning cassette with pads which scrub the tape
head as the hubs of the cleaner cassette turn. The
recommended cleaning cassette is available through
your dealer
(GM Part No. 12344789).
The cut tape detection feature of your cassette tape
player may identify the cleaning cassette as a damaged
tape, in error. To prevent the cleaning cassette from
being ejected, use the following steps:
1.
2.
3.
4.
5.
Turn the ignition on.
Turn the radio
off.
Press and hold the CD TAPE button for five
seconds. The tape symbol on the display will flash
for two seconds.
Insert the scrubbing action cleaning cassette.
Eject the cleaning cassette after the manufacturer’s
recommended cleaning time.
After the cleaning cassette is ejected, the cut tape detection feature will be active again.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt
to
clean the tape head. This type of cleaning cassette will
not eject on its own. A non-scrubbing action cleaner
may not clean as thoroughly as the scrubbing type
cleaner. The use of a non-scrubbing action, dry-type
cleaning cassette is not recommended. After
you clean the player, press and hold the EJECT
button for five seconds to reset the CLN indicator.
The radio will display
--- to show the indicator was reset.
Cassettes are subject
to wear and the sound quality
may degrade over time. Always make sure the cassette
tape is in good condition before you have your tape
player serviced.
Care of Your CDs and DVDs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen
a clean, soft cloth in a mild, neutral detergent solution
and clean it, wiping from the center to the edge.
Be sure never
to touch the side without writing when
handling discs. Pick up discs by grasping the outer
edges or the edge of the hole and the outer edge.
Care of Your CD Changer
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens
of the CD optics
with lubricants internal
to the CD mechanism.

Stabilitrak@ System
Your vehicle is equipped with Stabilitrak@, which
combines antilock brake, traction and stability control
systems and helps the driver maintain directional control
of the vehicle in most driving conditions.
When you first start your vehicle and begin
to drive
away, the system performs several diagnostic checks
to
insure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle. The system
should initialize before the vehicle reaches
20 m.p.h.
(32 km/h). In some cases, it may take approximately two
miles
of driving before the system initializes.
If the system fails
to turn on or activate, the STABILITY
SYS DISABLED or SERVICE STABILITY message
will be displayed.
If the vehicle has gone through heavy
acceleration or braking or multiple turns during the
first two miles of driving after starting your vehicle, the
STABILITY
SYS DISABLED message may appear.
If this is the case, your vehicle does not need servicing.
You will need
to turn the vehicle off and then restart
it
to initialize Stabilitrak@.
If either message appears on the Driver Information
Center (DIC), and your vehicle hasn’t gone through hard
acceleration, braking
or multiple turns in the first two
miles of driving, your vehicle should be taken in
for service. The STABILITY SYS ACTIVE message will appear
on
the Driver Information Center (DIC) only when the
system is both on and activated. You may also feel or
hear the system working; this is normal. For more
information on
the stability messages, see Driver
Information Center (DIC) on page 3-43.
Stabilitrak@and part of the
traction control system can
be turned
off or back on
by pressing the
Stabilitrak@button located
on the instrument
When the system is turned
off, the traction off light will
illuminate, and the STABILITY SYS DISABLED
message will appear on the DIC to warn the driver that
both the stability system and part of the traction
control system are disabled. Your vehicle will still have
brake-traction control when Stabilitrak@is
off, but will
not be able
to use the engine speed management
system. See “Traction Control Operation” next for more
information.
4-9

When the Stabilitrak@system has been turned off you
may still hear system noises as a result of the
brake-traction control coming on.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary
to turn
the system
off if your vehicle is stuck in sand, mud, ice
or snow, and you want
to “rock” your vehicle to
attempt to free it. It may also be necessary to turn off
the system when driving in extreme off-road conditions
where high wheel spin is required. See If
You Are
Stuck: In Sand, Mud, Ice or Snow on page
4-4 1.
Traction Control Operation
The traction control system is part of the
Stabilitrak@system. Traction control limits wheel spin by
reducing engine power
to the wheels (engine speed
management) and by applying brakes
to each individual
wheel (brake-traction control) as necessary.
The traction control system is enabled automatically
when you start your vehicle, and it will activate
and display the TRACTION ACTIVE message in the
Driver Information Center (DIC)
if it senses that any of
the wheels are spinning or beginning to lose traction
while driving. If you turn
off Stabilitrak@, only the
brake-traction control portion
of traction control will
work. The engine speed management will be disabled.
In this state, engine power is not reduced automatically
and the driven wheels can spin more freely. This
can cause the brake-traction control
to activate
constantly. For more information on the traction active
message, see Driver Information Center (DIC) on
page
3-43.
Notice: If the traction off light comes on due to
heavy braking and/or because the traction control
system has been continuously active, do not allow
the wheel@) of one axle to spin excessively.
If you
do, you may be causing damage to your transfer
case. This could lead to costly repairs not covered by
your warranty.
If the brake-traction control system activates constantly
or
if the brakes have heated up due to high speed
braking, the brake-traction control will be automatically
disabled. The system will come back on after the
brakes have cooled. This can take up
to two minutes ot
longer depending on brake usage.
Notice: Don’t allow the wheel(s) of one axle to spin
excessively when the traction
off, ABS and brake
lights are on and the
SERVICE STABILITY MESSAGE
is displayed. In this situation, damage to the transfer
case
is possible. This could lead to costly repairs not
covered by your warranty. You should immediately
reduce engine power until the lights and messages
are no longer displayed.
