DIC Warnings and Messages
These warning messages will appear in the DIC display
if there is a problem detected in one of your vehicle’s
systems. With most messages, a warning chime
will sound when the message is displayed.
The messages will clear from the display when the
condition no longer exists. You can also acknowledge
and clear some messages from the display by pressing
and holding either the reset or information buttons.
The message will come back on the next time the
vehicle is turned off and back on if the condition still
exists. Your vehicle may have other warning messages.
AUTO (Automatic) LIGHTS OFF
This message will display if the automatic headlamp
system is disabled with the headlamp switch.
SeeAutomatic Headlamp System on page 3-15for
more information.
AUTO (Automatic) LIGHTS ON
This message will display if the automatic headlamp
system is enabled with the headlamp switch.
SeeAutomatic Headlamp System on page 3-15for
more information.
BRAKE FLUID
This message will display to inform the driver that the
brake uid level is low while the ignition is on. Have the
brake system serviced by your GM dealer as soon
as possible.
CHANGE OIL SOON
This message will display when the life of the engine oil
has expired and it should be changed.
When you acknowledge the CHANGE OIL SOON
message by clearing it from the display, you still must
reset the engine oil life system separately. SeeEngine
Oil Life System on page 5-16andScheduled
Maintenance on page 6-4for more information.
CHECK GAS CAP
This message will display if the gas cap has not been
fully tightened. You should recheck your gas cap to
make sure that it is on properly. A few driving trips with
the cap properly installed should turn the message off.
CRUISE ENGAGED
This message will display when the cruise control
system is active. SeeCruise Control on page 3-11for
more information.

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 are driving, brake
normally but do not 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.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modifications
on page 5-3.Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake System
(ABS), an advanced electronic braking system that will
help prevent a braking skid.
If your vehicle has ABS,
this warning light on the
instrument panel will come
on briey when you
start your vehicle.
When you start your engine, or when you begin to drive
away, your ABS 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.

{CAUTION:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing
this, and some have been blinded. Use a
ashlight if you need more light.
Be sure the battery has enough water. You do
not need to add water to the battery installed
in your new vehicle. But if a battery has ller
caps, be sure the right amount of uid is there.
If it is low, add water to take care of that rst.
If you don’t, explosive gas could be present.
Battery uid contains acid that can burn you.
Do not get it on you. If you accidentally get it
in your eyes or on your skin, ush the place
with water and get medical help immediately.
{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.
5. Check that the jumper cables do not have loose
or missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go
to positive (+) or to a remote positive (+) terminal
if the vehicle has one. Negative (−) will go to a
heavy, unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative (−)oryou
will get a short that would damage the battery
and maybe other parts too. And do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.

Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your vehicle
unless you check with your dealer rst. Some
electrical equipment can damage your vehicle and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an airbag system. Before attempting
to add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-72.
Headlamp Wiring
The headlamp wiring is protected by fuses. Should
your headlamps fail to function, have your headlamp
system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow or ice, the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it xed.
Power Windows and Other Power
Options
Fuses in the fuse block protect the power windows.
When the current load is too heavy, the fuse opens
protecting the circuit until the problem is xed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of damage caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure
you replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and do not have
a spare fuse, you can “borrow” one that has the same
amperage. Just pick some feature of your vehicle
that you can get along without — like the radio or
cigarette lighter — and use its fuse if it is the correct
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the oor
console fuse block and the engine compartment
fuse block.
