Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine
is in ON/RUN.
That is normal. If the light does not come on then, have
it fixed so it will be ready to warn if there is a problem.
If the ABS light stays on, turn the ignition off, if the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS 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 not antilock
brakes. If the regular brake system warning light is
also on, the vehicle does not have antilock brakes
and there is a problem with the regular brakes.
SeeBrake System Warning Light on page 3-6.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-12for all
brake related DIC messages.
StabiliTrak®Indicator Light
For vehicles with
StabiliTrak, this warning
light comes on briefly when
the ignition is in ON/RUN.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light goes off.
When this light flashes, the system is on.
If it stays on while driving, there may be a problem with
the StabiliTrak system and the vehicle may need
service. See the owner manual for more information.

Notice:
Using the wrong uid can badly damage brake
hydraulic system parts. For example, just a
few drops of mineral-based oil, such as engine
oil, in the brake hydraulic system can damage
brake hydraulic system parts so badly that they
will have to be replaced. Do not let someone
put in the wrong kind of uid.
If brake uid is spilled on the vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on the
vehicle. If you do, wash it off immediately.
See “Washing Your Vehicle” in the owner
manual.
Brake Wear
This vehicle has disc brakes. Disc brake pads have
built-in wear indicators that make a high-pitched warning
sound when the brake pads are worn and new pads
are needed. The sound can come and go or be heard all
the time the vehicle is moving, except when applying
the brake pedal firmly.
{CAUTION:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to an
accident. When the brake wear warning sound is
heard, have the vehicle serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates can cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
the brakes.
