2002 BUICK PARK AVENUE warning light

2-77
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Battery Warning Light
When you turn the key to
RUN, this light will come
on briefly, to show the
battery charging system
is working.
When the light goes off and stays off, the charging
system is working.
If the light stays on, a chime will sound indicating
you need service, and you should take your vehicle to
the dealer at once. To save your battery until you get
there, turn off all accessories and turn off your climate
control system.

2-78
Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
when you turn the key to
RUN. If it doesn't come on
then, have it fixed so it will
be ready to warn you if
there's a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn't release
fully. If you try to drive off with the parking brake set,
a chime will also come on until you release the parking
brake. If the light stays on after your parking brake is
fully released, it means you have a brake problem.

2-79 Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when your engine
is started and may stay
on for several seconds.
That's normal.
If the light stays on and the chime sounds, turn the
ignition to OFF. Or, if the light comes on and the chime
sounds when 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 and the chime
sounds, or the light comes on again while you're
driving, your vehicle needs service. If the regular brake
system warning light isn't on, you still have brakes, but
you don't have anti
-lock brakes. If the regular brake
system warning light is also on, you don't have anti
-lock
brakes and there's a problem with your regular brakes.
See ªBrake System Warning Lightº earlier in
this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. 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 Warning
Light (Option)
This warning light should
come on briefly when the
engine is started.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem. If it
stays on, or comes on when you're driving, there may be
a problem with your traction control system and your
vehicle may need service. When this warning light is
on, the system will not limit wheel spin. Adjust your
driving accordingly.

2-80
The traction control system warning light may come on
for the following reasons:

If you turn the system off by pressing the button
located on the end of the shift lever, 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 ªTraction Control Systemº in the
Index for more information.

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off, the warning light will come on and the
chime will sound.

If the traction control system is affected by an
engine
-related problem, the system will turn off,
the warning light will come on and the chime
will sound.
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.
Engine Coolant Temperature Gage
This gage measures the
temperature of the vehicle's
engine. If the pointer
moves into the red area,
the engine is too hot.
A temperature indicator
light will turn on and a
chime will sound.
If you have been operating your vehicle under normal
driving conditions, and the temperature indicator light
comes on, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.

2-85
CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered
by your warranty.
Service Vehicle Soon Light
This light will come
on if your vehicle has
certain non
-emission
related problems.
For example, if the entire electrical system fails to
send and receive messages from the vehicle's
components, the SERVICE VEHICLE SOON
warning light comes on.
These problems may not be obvious and may affect
vehicle performance or durability. Consult a qualified
dealership for necessary repairs to maintain top vehicle
performance. This light will come on briefly when the
ignition is turned on to show that it is working properly.

2-86

Your vehicle is equipped
with a content
theft
-deterrent alarm
system. With this system,
the SECURITY light will
flash as you open the door
(if your ignition is off).
For more information see ªContent Theft
-Deterrentº in
the Index.
Cruise Light
The CRUISE light comes
on when you set the
vehicle's cruise control.
See ªCruise Controlº in
the Index.
Fuel Gage
United States Canada
The fuel gage shows about how much fuel is in your
tank. It works only when the ignition is on. When the
indicator moves to the edge of the low fuel warning
band, the low fuel warning light will come on and a
chime will sound. You still have a little fuel left, but you
need to get more fuel right away.

2-97
Head-Up Display (HUD)
(If Equipped)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.
The information may be displayed in English or metric
units and appears as a reflection in the windshield. The
HUD consists of the following information:

Speedometer Reading

Turn Signal Indicators

High
-Beam Headlamp Indicator

CHECK GAGES Message
The HUD shows these images when they are lighted on
the instrument panel cluster.
Be sure to continue scanning your displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel, you may not see something important, such
as a warning light.

4-7
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 has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
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.
If there's a problem with
the anti
-lock brake system,
this warning light will stay
on. See ªAnti
-Lock Brake
System Warning Lightº in
the Index.
