PONTIAC GRAND PRIX 2007 Owners Manual

Tachometer
The tachometer displays
the engine speed in
revolutions per
minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty. Do not
operate the engine with the tachometer in
the shaded warning area.
Safety Belt Reminder Light
When the key is turned to RUN or START, a
chime will sound for several seconds to remind
you and your passengers to buckle your
safety belts. The driver safety belt light will also
come on and stay on for several seconds, then it
will ash for several more. You should buckle
your seat belt.
If the driver’s belt is
buckled, neither the
chime nor the light will
come on.
171

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds to
remind the front passenger to buckle their safety
belt. This would only occur if the passenger airbag
is enabled. SeePassenger Sensing System on
page 74for more information. The passenger
safety belt light will also come on and stay on for
several seconds, then it will ash for several more.
If the passenger’s safety
belt is buckled, neither
the chime nor the
light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel cluster, which shows the airbag
symbol. The system checks the airbag’s
electrical system for malfunctions. The light
indicates if there is an electrical problem. The
system check includes the airbag sensors,
the airbag modules, the wiring, and the diagnostic
module. For more information on the airbag
system, seeAirbag System on page 64.
This light will come on
when the vehicle is
started, and it will ash
for a few seconds. Then
the light should go out.
This means the system is functioning properly.
If the airbag readiness light stays on after the
vehicle is started, or comes on as the vehicle is
being driven, the airbag system may not work
properly. Have the vehicle serviced right away.
172

{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 the ignition key is turned 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.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
The vehicle’s instrument panel has a passenger
airbag status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. If you use
remote start to start your vehicle from a distance,
if your vehicle has this feature, you may not
see the system check. Then, after several more
seconds, the status indicator will light either ON or
OFF, or either the on or off symbol to let you
know the status of the right front passenger’s
frontal airbag.
United StatesCanada
173

If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is enabled
(may inate).
{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag.
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
174

If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 74for more on this,
including important safety information.
If, after several seconds, all 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 for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, 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 seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 172.
Up-Shift Light
If your vehicle has this
light, it will come on
when the shift lever is in
the manual transaxle
position.
It will appear as a prompt to up-shift to the next
gear using one of the Tap-Shift
®paddles located
on the steering wheel.
If your vehicle has the Head-Up Display (HUD), it
will only appear on it.
SeeAutomatic Transaxle Operation on page 110
andHead-Up Display (HUD) on page 151for
more information.
175

Brake System Warning Light
The vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop the vehicle. For
good braking, though, both parts should be
working well.
This light should come on briey when the ignition
key is turned to RUN. If it does not come on
then, 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 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 200for 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 200for 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. See
Towing Your Vehicle on page 322.

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 176.
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. See
Brake System Warning Light on page 176. 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.
177

Low Tire Pressure Warning Light
This light should come
on briey as you start
the engine.
This light will also come on when one or more of
your tires is signicantly under-inated. Stop and
check your tires as soon as it is safe to do so.
If underinated, inate them to the proper pressure.
SeeTires on page 400for more information. This
light will ash for 60 seconds and then turn on solid
if a problem is detected with the Tire Pressure
Monitor System. SeeTire Pressure Monitor System
on page 409for more information.
Traction Control System (TCS)
Warning Light
If the vehicle has the
Traction Control
System (TCS), this light
may come on for the
following reasons:
The traction control button, located on the
center console, is pressed, turning the
system off. The light will stay on. To turn the
system back on, press the button again
and the warning light should go out. See
Traction Control System (TCS) on page 292
for more information.
If there is a brake system problem that is
specically related to traction control, the TCS
will turn off and the warning light will come on.
If the brakes begin to overheat, the TCS will
turn off and the warning light will come on until
the brakes cool down.
If the TCS warning light comes on and stays on
for an extended period of time when the system is
turned on, the vehicle needs service.
178

Enhanced Traction System
Warning Light
If the vehicle has the
Enhanced Traction

period of time when the system is turned on,
the vehicle needs service.
Engine Coolant Temperature
Warning Light
This light indicates that
the engine coolant has
overheated or the
radiator cooling fan is
not working.
If the vehicle has been operating under normal
driving conditions, pull off the road, stop the
vehicle, and turn off the engine as soon as
possible.
SeeCooling System on page 366for more
information.
179

Engine Coolant Temperature Gage
The vehicle has a gage
that shows the engine
coolant temperature.
If the gage pointer moves into the shaded area,
the engine is too hot. That reading means
the engine coolant has overheated. If you have
been operating the vehicle under normal
driving conditions, you should pull off the road,
stop the vehicle, and turn off the engine as soon
as possible.
SeeCooling System on page 366for more
information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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.
