Warning Lights,
Gages, and Indicators
This section describes the warning
lights and gages on the vehicle.
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 the
warning lights and gages could
prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate
they are working.Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages and
warning lights work together to
indicate a problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual’s advice.
Waiting to do repairs can be
costly and even dangerous.
4-10 Instruments and Controls
2008 - Pontiac G8 Owner Manual

Airbag Readiness Light
There is an airbag readiness
light which shows the airbag symbol.
The system checks the airbag’s
electrical system for malfunctions.
The light tells you if there is an
electrical problem. The system
check includes the airbag sensor,
the pretensioners, the airbag
modules, the wiring and the crash
sensing and diagnostic module.
For more information on the airbag
system, seeAirbag System on
page 1-19.
This light will come on when you
start your vehicle, and it will ash for
a few seconds. The light should
go out and the system is ready.If the airbag readiness light and the
Airbag Fault message on the
Driver Information Center (DIC)
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.The airbag readiness light should
ash for a few seconds when
you start the vehicle. If the light does
not come on then, have it xed
immediately. If there is a problem
with the airbag system, a message
may also come on. SeeDIC
Warnings and Messages on
page 4-27for more information.
The message will remain until

Brake System Warning
Light
Your vehicle’s hydraulic brake
system is divided into two parts. If
one part is not 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.If your vehicle has anti-lock brakes,
this light should come on when
you turn the key to START. If it does
not come on, have it xed so it
will be ready to warn you if there is
a problem.
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 does not release
fully. If it stays on after your
parking brake is fully released, it
means you have a brake problem.
If the light comes on and Brake
message comes on the Driver
Information Center (DIC), 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. SeeAntilock
Brake System (ABS) Warning Light
on page 4-17andTowing Your
Vehicle on page 9-84.
{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.
The Brake message will remain until
3(Trip/Fuel) or8(Enter) are
pressed, but the brake light will
remain until the problem is xed. See

Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light will come
on briey, as a check, when
you start your vehicle.
If it does not, have your vehicle
serviced so that the light works
properly when it needs to.
If the light and a message in the
DIC stays on longer than a few
seconds after you start your engine,
or comes on and stays on while
you are driving, try resetting
the system. To reset the system:
1. If you are driving, pull over when
it is safe to do so.
2. Place the vehicle in PARK (P).
3. Turn off the ignition.
4. Then restart the engine.If the light remains on after resetting
the system or comes on again
while driving, your vehicle needs
service. If the ABS light is on,
but the regular brake system
warning light is not on, the antilock
brakes are not working properly,
but the regular brakes are still
functioning. Have your vehicle
serviced right away. If both brake
lights are on, you do not have
antilock brakes, and there’s a
problem with your regular brakes as
well. Have your vehicle towed for
service. SeeTowing Your Vehicle
on page 9-84.
The ABS Fault message will remain
until
3(Trip/Fuel) or8(Enter)
are pressed, but the warning
light will remain until the problem is
xed. SeeDIC Warnings and
Messages on page 4-27for more
information.

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 9-49
andTire Pressure Monitor Operation
on page 9-51for more information.

Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It makes sure that
emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on briey, as a
check to show it is working,

pump shuts off before the
gage reads full.
It takes a little more or less fuel
to ll up than the gage indicated.

you turn a corner or speed up.
The gage will continue to show
the remaining fuel when the
