Hazard Warning Flashers
Your hazard warning ashers let you warn others.
They also let police know you have a problem. Your
front and rear turn signal lamps will ash on and off.
The hazard warning
asher button is located
on top of the steering
column.
Your hazard warning ashers work no matter what
position your key is in, and even if the key is not in
the ignition.
Press the button to make the front and rear turn
signal lamps ash on and off. Press the button again
to turn the ashers off.
When the hazard warning ashers are on, your turn
signals will not work.
Other Warning Devices
If you carry re ective triangles, you can set them up
at the side of the road about 300 feet (100 m) behind
your vehicle.
Horn
Press near or on the horn symbols on your steering
wheel pad to sound the horn.
Tilt Wheel
You should adjust the
steering wheel before
you drive. The tilt lever
is located to the left of the
steering column, under
the turn signal lever.
You can raise it to the highest level to give your legs
more room when you enter and exit the vehicle.
To tilt the wheel, hold the steering wheel and pull
the lever toward you. Move the steering wheel to a
comfortable level, then release the lever to lock
the wheel in place.

Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention
to your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on brie y when you start the engine
just to let you know they’re working. If you are familiar
with this section, you should not be alarmed when
this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice.
Waiting to do repairs can be costly — and even
dangerous. So please get to know your warning lights
and gages. They’re a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 3-43.

Charging System Light
The charging system light
will come on brie y when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have
a problem with the charging system. It could indicate
that you have problems with a generator drive belt,
or another electrical problem. Have it checked
right away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as
the radio and air conditioner.
Voltmeter Gage
When your engine is not
running, but the ignition
is in RUN, this gage shows
your battery’s state of
charge in DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between
the low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating
in the vehicle and the engine is left idling for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading
in either warning zone. If you must drive, turn off
all unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.

Brake System Warning Light
When the ignition is on, the brake system warning
light will come on when you set your parking brake.
The light will stay on if your parking brake doesn’t
release fully. If it stays on after your parking brake
is fully released, it means you have a brake problem.
A chime may also sound when the light comes on.
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 could be a brake
problem. Have your brake system inspected right away.
This light should come on brie y when you turn the
ignition key to RUN. If it doesn’t come on then, have it
xed 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 oor. It may take longer to stop. If the light is still
on, have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-50.
{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 have pulled off the road and
stopped carefully, have the vehicle towed
for service.

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on
for several seconds, that
is normal. A chime may
also sound when the
light comes on.
If the light stays on, or comes on when you are
driving, your vehicle needs service. If the regular brake
system warning light is not on, you still have brakes,
but you do not have anti-lock brakes. If the regular
brake system warning light is also on, you do not
have anti-lock brakes and there is a problem with
your regular brakes. SeeBrake System Warning
Light on page 3-33earlier in this section.
The anti-lock brake system warning light should
come on brie y when you turn the ignition key to
RUN. If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.
StabiliTrak®Service Light
This light will come on
brie y when the engine
is started.
This light will come on if a problem is detected in
the StabiliTrak
®system.
For more information seeStabiliTrak
®System
on page 4-9.

StabiliTrak®Indicator Light
This warning light should
come on brie y when the
engine is started.
During most driving conditions, this light will not come
on. If the StabiliTrak
®System is actively controlling
the stability and/or traction of the vehicle, this light will
blink. This is normal.
This light will come on if any portion of the system
has been manually turned off or a problem is detected
in the system.
If your vehicle is equipped with a Driver Information
Center, a message will appear also, seeDIC Warnings
and Messages on page 3-47andStabiliTrak
®System
on page 4-9for more information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area, the engine
coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-26.

Service All-Wheel Drive Light
This light should come on
brie y when you turn on
the ignition, as a check to
show you it is working.
The service all-wheel drive light comes on to indicate
that there may be a problem with the drive system and
service is required. Malfunctions can be indicated by
the system before any problem is apparent, which may
prevent serious damage to the vehicle. This system
is also designed to assist your GM dealer in correctly
diagnosing a malfunction.
Check Gages Warning Light
The check gages light will
come on brie y when you
are starting the engine.
If the light comes on and stays on while you are driving,
check your coolant temperature and engine oil pressure
gages to see if they are in the warning zones.
Gate Ajar Light
If this light comes on,
your liftgate or liftglass
is not completely shut.
Close the liftgate or liftglass. Never drive with the
liftgate or liftglass even partially open.

Fuel Gage
When the ignition is on, the fuel gage tells you about
how much fuel you have remaining.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the gas station, the gas pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took
a little more or less than half the tank’s capacity
to ll the tank.
The gage moves a little when you turn a corner
or speed up.
The gage doesn’t go back to empty when you turn
off the ignition.
Low Fuel Warning Light
The light next to the fuel gage will come on brie y when
you are starting the engine.
This light comes on when the fuel tank is low on fuel. To
turn it off, add fuel to the fuel tank. SeeFuel on page 5-5
.
Check Gas Cap Light
If equipped, this light will
come on if your gas cap is
not securely fastened.
