Playing a CD
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, READING and the CD
symbol appears on display. As each new
track starts to play, the track number appears
on the display.
The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs
and the smaller CDs are loaded in the same
manner.
If playing a CD-R, the sound quality may be
reduced due to CD-R quality, the method of
recording, the quality of the music that has been
recorded, and the way the CD-R has been
handled. There may 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 231for more information.
If there is no apparent damage, try a known
good CD.

Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features
intended to minimize driver distraction. Technology
alone, no matter how advanced, can never
replace your own judgment. See the Navigation
System manual for some tips to help you
reduce distractions while driving.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft
of your vehicle’s radio. The feature works
automatically by learning a portion of the
Vehicle Identication Number (VIN). If the radio
is moved to a different vehicle, it does not
operate and LOCKED displays.
When the radio and vehicle are turned off, the
blinking red light indicates that THEFTLOCK
®
is armed.
With THEFTLOCK
®activated, the radio does
not operate if stolen.
Radio Reception
You may experience frequency interference and
static during normal radio reception if items
such as cellphone chargers, vehicle convenience
accessories, and external electronic devices
are plugged into the accessory power outlet.
If there is interference or static, unplug the item
from the accessory power outlet.
AM
The range for most AM stations is greater than
for FM, especially at night. The longer range can
cause station frequencies to interfere with each
other. For better radio reception, most AM
radio stations will boost the power levels during
the day, and then reduce these levels during
the night. Static can also occur when things like
storms and power lines interfere with radio
reception. When this happens, try reducing the
treble on your radio.

Section 4 Driving Your Vehicle
233

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. The brakes may not have time to
cool between hard stops. The 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 vehicle ever loses electrical power while you
are driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to push
down. If your vehicle loses electrical power, 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, the brake pedal will
be harder to push, and you may experience longer
pedal travel.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 314Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
When you start your engine and begin to drive
away, ABS will check itself. You may hear a
momentary motor or clicking noise while this
test is going on. This is normal.
If there is a problem
with ABS, this warning
light will stay on.
SeeAnti-Lock Brake
System Warning
Light on page 183.
239

Remember: ABS 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 ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You may feel the brakes vibrate, or you may
notice some noise, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same
time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
Your vehicle has a Traction Control System (TCS)
that limits wheel spin. This is especially useful
in slippery road conditions. The system operates
only if it senses that any of the wheels are spinning
or beginning to lose traction. When this happens,
the system applies the brakes to limit wheel
spin and also reduces engine power. You may
feel or hear the system working, but this is normal.
The Traction Control System may operate on dry
roads under some conditions. When this happens,
you may notice a reduction in acceleration or a
pumping sound. This is normal and doesn’t mean
there’s a problem with your vehicle. Examples of
these conditions include hard acceleration in a turn,
an abrupt upshift or downshift of the transmission
or driving on rough roads.
If your vehicle is in cruise control when the TCS
begins to limit wheel spin, the cruise control will
automatically disengage. When road conditions
allow you to safely use it again, you may re-engage
the cruise control. SeeCruise Control on page 159.
241

If your vehicle has a Driver information Center
(DIC), a TRACTION FAILED message will appear
when a Traction Control System or Anti-Lock
Brake System problem has been detected and the
vehicle needs service. SeeDIC Warnings and
Messages on page 196for more information.
When this message is on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes
on whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you
should always leave the system on. But you
can turn the traction control system off if you
ever need to.
To turn the system off,
press and hold the TCS
button for ve seconds.This light will come
on steady when the
traction control system
has been turned off.
This light ashes
when TCS is active.
If you press and hold the TC button for
ve seconds, the traction control system will turn
off and a TRAC OFF message will appear on
the DIC. Press the TC button again to turn
the system back on. The TRAC OFF message
will then go off. The traction control system
will reset itself at each ignition cycle.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 314for more information.
