If You Can’t See the HUD Image When
the Ignition
Is On
Is anything covering the HUD unit?
Is the HUD dimmer setting bright enough?
Is the HUD image adjusted to the proper height?
Still no HUD image? Check the fuse in the
instrument panel fuse block. See Fuses and
Circuit
Breakers on page 5-97.
If the HUD Image Is Not Clear
Is the HUD image too bright?
Are the windshield and HUD lens clean?
The windshield is part of the HUD system.
If you ever
need a new windshield, be sure to get one designed for
HUD.
If you don’t, the HUD image may look blurred
and out of focus.
Accessory Power Outlets
Your vehicle has a 12-volt outlet which can be used
to plug in electrical equipment such as a cellular
telephone, a compact disc player, etc. It is located on
the passenger’s side, near the floor. Remove the tethered cap
to use the outlet. When not
using the outlet, be sure
to cover it with the
protective cap.
The accessory power outlet will only operate while the
ignition is on and for a few minutes after turning the
ignition
off. If you would like to operate an accessory for
an extended period of time, see your dealer for more
information.
Notice: When using an accessory power outlet,
maximum electrical load must not exceed amperage
rating. Always turn
off any electrical equipment
when not in use. Leaving electrical equipment on
for extended periods will drain your battery.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses.
If you experience a
problem, see your dealer for additional information
on the accessory power plugs.

change the direction
of the airflow.
Operation Tips
e
e
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
Use of non-GM approved hood deflectors
may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside
of your vehicle more
effectively.

Anti-Lock Brake System Warning Light
if your vehicle has the
optional anti-lock brake
system, this light will come
on when your engine is
started and may stay on
for several seconds.
That’s normal.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition
off. If the light comes on and stays on
while you’re driving, stop as soon as possible and turn
the ignition
off. Then start the engine again to reset
the system.
If the light still stays on, or comes on again
while you’re driving, your vehicle needs service.
If
the light is on and the regular brake system warning
light isn’t on, you still have brakes, but you don’t have
anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. This is
normal.
If the light doesn’t come on then, have it
fixed
so it will be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
TCS

button located on the far right side of the trip
computer, the warning light will come on and stay
on. To turn the system back on, press the button
again. The warning light should go
off. See Traction
Control System (TCS) on page
4-10 for more
information.
@ If there’s a brake system problem that is specifically
related to traction control, the traction control
system will turn
off and the warning light will come
on. If your brakes begin to overheat, the traction
control system will turn
off and the warning light will
come on until your brakes cool down.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system
is turned on, your vehicle needs service.

Functions
__ (Door Ajar): If one of the doors is ajar, this light
will appear next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when the

system predicts remaining oil life using data from length
of drives, coolant temperature, engine rpm and
vehicle speed. It alerts you to change the oil on a
schedule consistent with the vehicle’s driving conditions.
After changing the oil, the system must be reset. See
How to Reset the GM
Oil Life SystemTM under
Engine

page 3-30.
TRAC (Traction): If the vehicle has anti-lock brakes
and the enhanced traction system, you will have a
disable button on the far right side of the DIC.
The enhanced traction system is automatically activated
when you turn the ignition on. This button will
activate/deactivate the system. If you need to disable
the system, such
as when you are stuck and are rocking

corrected, contact your dealer.
If your radio displays an
error number, write it down and provide it to your
dealer when reporting the problem.
Theft-Deterrent Feature
THEFTLOCK@ is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is interrupted.
The THEFTLOCK feature for the radio may be used or
ignored.
If ignored, the system plays normally and
the radio is not protected by the feature. If THEFTLOCK
is activated, your radio will not operate
if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power is removed. If your battery loses power for any
reason, you must unlock the radio with the secret
code before it will operate.
Activating the Theft-Deterrent Feature
The instructions which follow explain how to enter
your secret code to activate the THEFTLOCK system.
Read through all nine steps before starting the
procedure.
If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time
and you must start the procedure over at Step 4.
1. Write down any three or four-digit number from 000
to 1999 and keep it in a safe place separate from
the vehicle.

And, of course, actual stopping distances vary greatly
with the surface of the road (whether it’s pavement
or gravel); the condition of the road (wet, dry, 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’re driving, brake
normally but don’t 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.
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 briefly 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.
