If the airbag readiness light stays on after you start the
vehicle or comes on when you are driving, your
airbag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the airbag readiness light stays on after you
start your vehicle, it means the airbag system
may not be working properly. The airbags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the airbag readiness light
stays on after you start your vehicle.
The airbag readiness light should ash for a few
seconds when you start the engine. If the light does not
come on then, have it xed immediately. If there is a
problem with the airbag system, an airbag Driver
Information Center (DIC) message may also come on.
SeeDIC Warnings and Messages on page 3-58for
more information.

status indicator.
When you start the
vehicle, the passenger
airbag status indicator will
light ON and OFF for
several seconds as

If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may be a
problem with the lights or the passenger sensing
system. See your dealer/retailer for service.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the airbag(s). SeeAirbag Readiness Light
on page 3-33for more on this, including
important safety information.

briey when you turn on
the ignition key, 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 driving, there could be a problem
with the charging system. A charging system Driver
Information Center (DIC) message may also appear.
SeeDIC Warnings and Messages on page 3-58
for more information. This light could indicate that there
are problems with a generator drive belt, or that
there is an electrical problem. Have it checked right

Antilock Brake System
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when the
engine is started.
That is normal. If the light does not come on then,
have it xed so it will be ready to warn you if there
is a problem.
If the ABS light stays on, turn the ignition off, if the light
comes on when you are driving, stop as soon as it is
safely possible and turn the ignition off. Then start
the engine again to reset the system. If the ABS light
still stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, your vehicle still has
brakes, but not antilock brakes. If the regular brake
system warning light is also on, your vehicle does not
have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-37.For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 3-58for all
brake related DIC messages.Traction Control System (TCS)

Low Coolant Warning Light
If your vehicle has this
light, it comes on briey
when you turn your ignition
on as a bulb check only.
Tire Pressure Light
Your vehicle has a tire
pressure light.
This light comes on briey when the engine is started
and provides information about tire pressures and
the Tire Pressure Monitoring System.
When the Light is Solid
This indicates that one or more of your tires are
signicantly underinated.
A tire pressure message in the Driver Information
Center (DIC), may accompany the light. SeeDIC
Warnings and Messages on page 3-58for more
information. Stop and check your tires as soon as it is
safe to do so. If underinated, inate to the proper
pressure. SeeTires on page 5-63for more information.
When the Light Flashes First and Then
is Solid
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light ashes for about
a minute and stays on solid for the remainder of
the ignition cycle. This sequence will repeat with every
ignition cycle. SeeTire Pressure Monitor System on
page 5-71for more information.

Service Vehicle Soon Light
For vehicles with this light,
it will come on if a
condition exists that may
require the vehicle to
be taken in for service.
If the light comes on, see your dealer/retailer for service
as soon as possible.
Fuel Gage
The fuel gage indicates
about how much fuel is left
in the fuel tank when the
ignition is on.
When the indicator nears empty, there is still a little fuel
left, but you should get more fuel soon.Here are four things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage:
At the gas station, the pump shuts off before the
gage reads full.
It takes more, or less, fuel to ll up than the gage
reads. For example, the gage reads half full, but
it took more, or less, than half of the tank’s capacity
to ll it.
The gage pointer may move while cornering,
braking or accelerating.
The gage may not indicate empty when the ignition
is turned off.
Low Fuel Warning Light
Your vehicle may have a low fuel light. It is a circle
located on the fuel gage and will come on and a chime
will sound periodically when the vehicle is low on fuel.
The light will go off when fuel is added to the fuel tank.
It will also come on for a few seconds when the ignition
is turned on as a check to indicate it is working. If it
does not come on then, have it xed.
For vehicles with a Driver Information Center (DIC), a
LOW FUEL message will appear. SeeDIC Warnings
and Messages on page 3-58for more information.

Check Gas Cap Light
If your vehicle has this
light, it will come on if your
gas cap is not securely
fastened.
SeeMalfunction Indicator Lamp on page 3-42for more
information.
Driver Information Center (DIC)
Your vehicle may have a Driver Information Center (DIC).
All messages will appear in the DIC display located in
the instrument panel cluster, below the speedometer.
The DIC buttons are located on the center of the
instrument panel, below the center outlets.
The DIC comes on when the ignition is on. After a short
delay, the uplevel DIC will display the WELCOME
DRIVER (1 or 2) if a personalized key 1 or 2 is used,
and then the information that was last displayed before
the engine was turned off.The base level DIC displays the odometer and trip
odometers only.
The uplevel DIC displays the odometer, trip odometers,
fuel economy, trip computer, vehicle system, and
compass display information. It also displays warning
messages if a system problem is detected. In addition,
the uplevel DIC displays phone numbers that are
called using the OnStar
®system, if equipped. See
OnStar®System on page 2-43.
The outside air temperature automatically appears in
the bottom right corner of the uplevel DIC display when
viewing the trip/odometer screens, fuel screens and
some of the gages screens. If the outside air
temperature is at or below 37°F (3°C), the temperature
reading will toggle between displaying the outside
temperature and the word ICE for two minutes. If there
is a problem with the system that controls the
temperature display, the letters OC (open circuit) or SC
(short circuit) will appear on the display. If this occurs,
have the vehicle serviced by your dealer/retailer.
The uplevel DIC also allows some features to be
customized or personalized. SeeDIC Vehicle
Personalization on page 3-76for more information.

DIC Compass (Uplevel Only)
Your vehicle may have a compass in the Driver
Information Center (DIC).
Compass Zone
The zone is set to zone eight upon leaving the factory.
Your dealer/retailer will set the correct zone for your
location.
Under certain circumstances, such as during a long
distance cross-country trip or moving to a new state or
province, it will be necessary to compensate for
compass variance by resetting the zone through the
DIC if the zone is not set correctly.
Compass variance is the difference between the earth’s
magnetic north and true geographic north. If the compass
is not set to the zone where you live, the compass may
give false readings. The compass must be set to the
variance zone in which the vehicle is traveling.
To adjust for compass variance, use the following
procedure:
Compass Variance (Zone) Procedure
1. Do not set the compass zone when the vehicle is
moving. Only set it when the vehicle is in PARK (P).
Press the option button until COMPASS ZONE
displays.
2. Find the vehicle’s current location and variance
zone number on the map.
Zones 1 through 15 are available.
