Brakes

Antilock Brake System (ABS)

The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. See Antilock Brake System
(ABS) Warning Light 0 82.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing or feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.

Parking Brake

Set the parking brake by holding the regular
brake pedal down, then pushing down the
parking brake pedal.
If the ignition is on, the brake system
warning light will come on. See Brake
System Warning Light 0 81.
Caution
Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake
system parts. Make sure that the parking
brake is fully released and the brake
warning light is off before driving.
To release the parking brake, hold the
regular brake pedal down, then push down
momentarily on the parking brake pedal
until you feel the pedal release. Slowly pull
your foot up off the parking brake pedal.
If the parking brake is not released when
you begin to drive, a DIC message will
appear and a chime will sound warning you
that the parking brake is still on.
