The brake master cylinder reservoir
is filled with DOT 3 brake fluid as
indicated on the reservoir cap. See
Engine Compartment Overview
0252 for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
. Normal brake lining wear. When
new linings are installed, the
fluid level goes back up.
. A fluid leak in the brake
hydraulic system. Have the
brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake hydraulic system.{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light 0122.
Brake fluid absorbs water over time.
Replace brake fluid at the specified
intervals to prevent increased
stopping distance. See Maintenance
Schedule 0329.
What to Add
Use only GM approved DOT 3
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0333.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
Battery
The original equipment battery is
maintenance free. Do not remove
the cap and do not add fluid.
The battery is in the trunk, behind
the trim panel, on the driver side of
the vehicle. Refer to the
replacement number shown on the
original battery label when a new
battery is needed.

The pressure gauge (3) may
read higher than the actual tire
pressure while the compressor
is on. Turn the compressor off
to get an accurate reading. The
compressor may be turned on/
off until the correct pressure is
reached.
If you inflate the tire higher
than the recommended
pressure you can adjust the
excess pressure by pressing
the pressure deflation
button (4) until the proper
pressure reading is reached.
This option is only functional
when using the air only
hose (7).
11. Press the on/off button (2) to turn the tire sealant and
compressor kit off.
Be careful while handling the
tire sealant and compressor kit
as it could be warm after

the vehicle. 13. Disconnect the air only hose
(7) from the tire valve stem, by
turning it counterclockwise, and
replace the tire valve stem cap.
14. Replace the air only hose (7) and the power plug (8) and
cord back in its original
location.
15. Place the equipment in the original storage location in the
vehicle.
The tire sealant and compressor kit
has an accessory adapter located in
a compartment on the bottom of its
housing that may be used to inflate
air mattresses, balls, etc.
Removal and Installation of the
Sealant Canister
To remove the sealant canister:
1. Unwrap the sealant/air hose to access the canister release
button.
