2005 PONTIAC GRAND PRIX brake fluid

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 3-69for
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 3-69for 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. United States

LOW BRAKE FLUID
This symbol comes on with
the LOW BRAKE FLUID
warning message.
This warning message will appear when the brake uid
level is low. Fill the brake master cylinder to the proper
level. SeeEngine Compartment Overview on page 5-12
for the location of the brake master cylinder reservoir.
Also, seeBrakes on page 5-40for proper uid level.
The brake light will also appear on the instrument panel
cluster when this message appears on the DIC.
This message will display only while the ignition is in
RUN. A chime will sound for two seconds while
this message is displayed. Press the set/reset button
to acknowledge this message and to clear it from
the screen.
This message will continue to display if it has not been
acknowledged when the engine is turned off. It will

Checking the Fluid Level
Prepare the vehicle as follows:
Park the vehicle on a level place. Keep the engine
running.
With the parking brake applied, place the shift lever
in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear, pausing for about three
seconds in each one. Then, position the shift lever
in PARK (P).
Let the engine run at idle for three to ve minutes.
Then, without shutting off the engine, follow these steps:
The transaxle uid dipstick
handle is the red loop
located near the rear of the
engine. SeeEngine
Compartment Overview on
page 5-12for more
information on location.
1. Pull out the dipstick and wipe it with a clean rag or
paper towel.2. Push it back in all the way, wait three seconds and
then pull it back out again.
3. Check both sides of the dipstick, and read the
lower level. The uid level must be in the
crosshatched area.
4. If the uid level is in the acceptable range, push
the dipstick back in all the way.

Brakes
Brake Fluid
Your brake master cylinder
reservoir is lled with
DOT-3 brake uid. See
Engine Compartment
Overview on page 5-12
for the location of the
reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down. The rst is that the
brake uid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the uid level goes back up. The other reason is
that uid is leaking out of the brake system. If it is, you
should have your brake system xed, since a leak
means that sooner or later your brakes will not work
well, or will not work at all.So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you add uid
when your linings are worn, then you will have too
much uid when you get new brake linings. You should
add or remove brake uid, as necessary, only when
work is done on the brake hydraulic system.
{CAUTION:
If you have too much brake uid, it can spill on
the engine. The uid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
uid only when work is done on the brake
hydraulic system.
When your brake uid falls to a low level, your brake
warning light will come on. SeeBrake System Warning
Light on page 3-40.
What to Add
When you do need brake uid, use only DOT-3 brake
uid. Use new brake uid from a sealed container
only. SeeRecommended Fluids and Lubricants on
page 6-12.
