ignition PONTIAC GRAND PRIX 2006 Service Manual

When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will stay on if the parking brake does not
release fully. If it stays on after the parking brake is fully
released, it means the vehicle has a brake problem.
The PARKING BRAKE ON message will also appear in
the Driver Information Center (DIC) when the parking
brake is set and the vehicle is going faster than 5 mph.
SeeDIC Warnings and Messages on page 3-72for
more information.
The brake warning light may also come on when the
brake uid is low. If this occurs, the LOW BRAKE FLUID
message will also appear in the Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 3-72for more information.If the brake warning light comes on while the vehicle is
being driven, pull off the road and stop carefully.
The brake pedal may be harder to push, or it may go
closer to the oor. It may also take the vehicle longer to
stop. If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-38.
{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
If the vehicle has the
Anti-lock Brake System
(ABS), this light will come
on when the engine is
started and may stay on
for several seconds.
That is normal.
If the ABS warning light comes on and stays on, there
may be a problem with the anti-lock portion of the brake
system. If the brake system warning light is not on,
the vehicle still has brakes, but it does not have anti-lock
brakes. SeeBrake System Warning Light on page 3-42.If the light stays on, the vehicle needs service. If the
light comes on while the vehicle is being driven, stop as
soon as possible and turn the ignition off. Then start
the vehicle again to reset the system. If the light
still stays on, or comes on again while driving, the
vehicle needs service. If the regular brake system
warning light is not on, the vehicle still has brakes, but it
does not have anti-lock brakes. If the brake system
warning light is also on, the vehicle does not have
anti-lock brakes and there is a problem with the regular
brakes. SeeBrake System Warning Light on page 3-42.
If both the brake system warning light and the anti-lock
brake system light is on, pull off the road and have
the vehicle towed for service.
The anti-lock brake system warning light will come on
briey when the ignition key is turned to RUN. This
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.
3-44

Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition, and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The check engine light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after awhile, your emission controls
may not work as well, your fuel economy may not
be as good, and your engine may not run as
smoothly. This could lead to costly repairs that may
not be covered by your warranty.Notice:Modications made to the engine,
transaxle, exhaust, intake, or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test. SeeAccessories
and Modifications on page 5-3.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
3-47

Oil Pressure Light
If there is a problem with
the vehicle’s oil pressure,
this light may stay on
when the engine is started,
or it may come on while
the vehicle is being driven.
This indicates that oil is not going through the engine
quickly enough to keep it lubricated. The engine
could be low on oil or could have some other oil
problem. Have it xed right away.
The oil light could also come on in two other situations:
When the ignition is on but the engine is not
running, the light will come on as a test to indicate
it is working. The light will go out when the
ignition is turned to RUN. If it does not come on
while the ignition is in the on position, there may be
a problem with the fuse or bulb. SeeFuses and
Circuit Breakers on page 5-112.
If the brakes are applied quickly and the vehicle
makes a hard stop, the light may come on for a
moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
Fog Lamp Light
This light will come on
when the fog lamps
are in use.
The light will go out when the fog lamps are turned off.
SeeFog Lamps on page 3-17for more information.
3-50

Cruise Control Light
This light comes on
whenever you set your
cruise control.
The light will go out when the cruise control is turned
off. SeeCruise Control on page 3-11for more
information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
See “Headlamp High/Low-Beam Changer” under
Exterior Lamps on page 3-15for additional information.
Fuel Gage
The fuel gage shows
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 soon.
Here are four things owners usually ask about the fuel
gage. All these situations are normal and do not
indicate a problem 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
indicates. For example, the gage reads half full,
but it took more or less than half the tank’s capacity
to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate full when the ignition is
turned off.
