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

To set the parking brake:
1. Hold the regular brake pedal down.
2. Firmly push the parking brake
pedal down.
3. The brake system warning light will
come on, if the ignition is on. See Brake
System Warning Light 0 77.
If you are towing a trailer and parking on a
hill, see Driving Characteristics and Towing
Tips 0 153.
To release the parking brake:
1. Hold the regular brake pedal down.
2. Pull the handle with the parking brake
symbol located just above the parking
brake pedal.
3. The brake system warning light will turn
off, if the ignition is on.
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.
Driving and Operating
Driving with the parking brake applied will
cause a warning chime to sound and a
Driver Information Center (DIC) message
may display. Release the parking brake or
stop the vehicle.

Brake Assist

Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brake
pedal pulsation, and/or pedal movement
during this time may occur. Continue to
apply the brake pedal as the driving
situation dictates. Brake Assist disengages
when the brake pedal is released.

Hill Start Assist (HSA)

Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
