Before leaving the vehicle, check the red
handbrake status light to ensure that the
handbrake is applied.
EPB Apply
To apply the EPB:
1. Be sure the vehicle is at a complete stop.
2. Press the EPB switch momentarily.
The red handbrake status light will flash and
then stay on once the EPB is fully applied.
If the red handbrake status light flashes
continuously, then the EPB is only partially
applied or there is a problem with the EPB.
A DIC message will display. Release the EPB
and try to apply it again. If the light does
not come on, or keeps flashing, have the
vehicle serviced. Do not drive the vehicle if
the red handbrake status light is flashing.
See your dealer.
If the amber parking brake service warning
light is illuminated, press the EPB switch.
Continue to hold the switch until the red
handbrake status light remains on. If the
amber parking brake service warning light is
illuminated, see your retailer.
If the EPB is applied while the vehicle is
moving, the vehicle will decelerate as long
as the switch is pressed. If the switch is
pressed until the vehicle comes to a stop,
the EPB will remain applied.
The vehicle may automatically apply the EPB
in some situations when the vehicle is not
moving. This is normal, and takes place to
periodically check the correct operation of
the EPB system, or at the request of other
safety functions that utilise the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:
1. Turn the ignition on or to
accessory mode.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red handbrake
status light is off.
If the amber parking brake service warning
light is illuminated, release the EPB by
pressing and holding the EPB switch.
Continue to hold the switch until the red
handbrake status light is off. If either light
stays on after release is attempted, see your
dealer.
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.
If you are towing a trailer and parking on a
hill, see
Driving Characteristics and Towing
.
Automatic EPB Release
The EPB will automatically release if the
vehicle is running, placed into gear and an
attempt is made to drive away. Avoid rapid
acceleration when the EPB is applied, to
preserve parking brake lining life.
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
