2004 PONTIAC GRAND PRIX brake

Turn Signal On Chime
If the turn signal is left on for approximately 1 mile
(1.61 km), a warning chime will sound and the TURN
SIGNAL ON warning message will appear on the Driver
Information Center (DIC) display. See ªTurn Signal
Onº under
DIC Warnings and Messages on page 3-65for more information.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
®rst sold in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
·It is still daylight and the ignition is in RUN or
START,
·the exterior lamp control is in off or AUTO with the
headlamps off, and
·an automatic transaxle is not in PARK (P) and the
parking brake is released.When DRL are on, only the front turn signal/parking
lamps will be on. No other exterior lamps will be
on when the DRL are being used. Your instrument
panel won't be lit up either.
When the exterior lamp control is in AUTO and it's dark
enough outside, the DRL will turn off and the low-beam
headlamps at full brightness will turn on. When it's
bright enough outside, the front turn signal lamps will
go off, and the DRL will turn back on. If you start
your vehicle in a dark garage, the automatic headlamp
system will come on immediately. Once you leave
the garage, it will take approximately one minute for the
automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make sure
your instrument panel brightness knob is in the full
bright position. See ªInstrument Panel Brightnessº under
Interior Lamps on page 3-16.
Vehicle's sold in the U.S. can turn the DRL off.
To do this, turn the band on the exterior lamp control
to off. Turn the band to this position again to turn
the DRL on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Brake System Warning Light
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 is 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.
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 doesn't
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.The PARKING BRAKE ON message will also appear in
the Driver Information Center (DIC) when the parking
brake is set.
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).
If the brake warning 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. See
Towing Your
Vehicle on page 4-33.
{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've pulled off the road and stopped
carefully, have the vehicle towed for service. United States

Anti-lock Brake System
(ABS), this light will come
on when your engine is
started and may stay on
for several seconds.
That's 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,
you still have brakes, but you don't have anti-lock
brakes. See
Brake System Warning Light on page 3-36.If the light stays on, turn the ignition to OFF. If the light
comes on when you're driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you're driving, your vehicle
needs service. If the regular brake system warning light
isn't on, you still have brakes, but you don't have
anti-lock brakes. If the brake system warning light is
also on, you don't have anti-lock brakes and there's a
problem with your regular brakes. See
Brake System
Warning Light on page 3-36.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition key to RUN. This
