CD Messages
No Maga:An empty magazine is inserted in the CD
changer. Try the magazine again with a CD loaded
in one of the trays.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer. If your radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.
Theft-Deterrent Feature
The theft-deterrent system is designed to discourage
theft of your radio. When the radio and vehicle are
turned off, your radio has a blinking red light to indicate
that the theft-deterrent system is activated.
The theft-deterrent system also activates when the
audio system has been disconnected from the battery.
When this occurs, the AF code and security code
will have to be entered in order to operate your radio.
An identification card stamped with the AF code
and security code will be provided with the vehicle.
Keep it in a safe place, not in the vehicle.To enter the security code do the following:
1. Turn the ignition to ACC or ON.
2. Turn the radio on. AF or COdE will flash on the
display. If AF flashes on the display, go to Step
2. If COdE flashes on the display, go to Step 4.
3. Enter the AF code by using the preset pushbuttons.
COdE will flash on the display.
4. Enter the security code by using the preset
pushbuttons. When the complete security code is
entered, the code will flash three times.
If the security code is not entered correctly, Err will
appear on the display for a few seconds. When
COdE appears back on the display, repeat Step 4.
If the incorrect AF code is entered, an incorrect
frequency level may be chosen and the radio
reception may be affected. If this occurs, reset the
audio system by removing and re-installing the
AUDIO fuse. See “Instrument Panel Fuse Block”
underFuses and Circuit Breakers on page 5-79for
more information. Then repeat Steps 1 through 4.

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
firmly and let anti-lock work for you. You may hear the
anti-lock pump or motor operate, and feel the brake pedal
pulsate, but this is normal.
Braking in Emergencies
With anti-lock, 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 may have 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 one or both of the front wheels are spinning
or beginning to lose traction. When this happens, the
system works the front brakes to limit wheel spin.
This light will come on
briefly when the ignition
is turned to ON along
with the anti-lock brake
system warning light.
This light will blink when
your Traction Control
System is limiting
wheel spin.
You may feel or hear the system working, but this is
normal. This light will also come on when the anti-lock
brake system is working.

•Do not get too close to the vehicle you want to pass
while you are awaiting an opportunity. For one thing,
following too closely reduces your area of vision,
especially if you are following a larger vehicle. Also,
you will not have adequate space if the vehicle
ahead suddenly slows or stops. Keep back a
reasonable distance.
•When it looks like a chance to pass is coming up,
start to accelerate but stay in the right lane and do
not get too close. Time your move so you will be
increasing speed as the time comes to move into the
other lane. If the way is clear to pass, you will have
a “running start” that more than makes up for the
distance you would lose by dropping back. And if
something happens to cause you to cancel your
pass, you need only slow down and drop back again
and wait for another opportunity.
•If other vehicles are lined up to pass a slow vehicle,
wait your turn. But take care that someone is not
trying to pass you as you pull out to pass the slow
vehicle. Remember to glance over your shoulder
and check the blind spot.
•Check your mirrors, glance over your shoulder, and
start your left lane change signal before moving out
of the right lane to pass. When you are far enough
ahead of the passed vehicle to see its front in your
inside mirror, activate your right lane change signal
and move back into the right lane. (Remember
that your right outside mirror is convex. The vehicle
you just passed may seem to be farther away from
you than it really is.)
•Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the
next vehicle.
•Do not overtake a slowly moving vehicle too rapidly.
Even though the brake lamps are not flashing, it may
be slowing down or starting to turn.
•If you are being passed, make it easy for the
following driver to get ahead of you. Perhaps you
can ease a little to the right.

Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to GM torque specifications.
Brake linings should always be replaced as complete
axle sets.
SeeBrake System Inspection on page 6-23.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply your brakes, with or without the
vehicle moving, your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality GM brake parts.
When you replace parts of your braking system — for
example, when your brake linings wear down and you
need new ones put in — be sure you get new approved
GM replacement parts. If you do not, your brakes may no
longer work properly. For example, if someone puts in
brake linings that are wrong for your vehicle, the balance
between your front and rear brakes can change — for the
worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.
5-34

After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the tire and loading
information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-85.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to,
to get all the rust or dirt off. See “Changing
a Flat Tire” in the Index.
When It Is Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need a new tire if any of the following statements
are true:
•You can see the indicators at three or more
places around the tire.
•You can see cord or fabric showing through the
tire’s rubber.
•The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
•The tire has a bump, bulge or split.
•The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or
location of the damage.

8. Remove any rust or dirt
from the wheel bolts,
mounting surfaces
and spare wheel.
{CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
the places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use
a scraper or wire brush later, if you need to,
to get all the rust or dirt off.
{CAUTION:
Never use oil or grease on studs or nuts.
If you do, the nuts might come loose. Your
wheel could fall off, causing a serious
accident.
9. Place the spare tire on the wheel-mounting surface.
10. Install the wheel nuts with the rounded end of the
nuts toward the wheel. Tighten each nut by hand
clockwise until the wheel is held against the hub.
11. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the jack completely.
12. Tighten the wheel nuts
firmly in a crisscross
sequence, as shown.
