238 Driving and Operating
The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake 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
parking brake status light is flashing.
See your dealer. See Electric
Parking Brake Light 0 135.
If the amber parking brake warning
light is on, hold down the EPB
switch. Continue to hold the switch
until the red parking brake status
light remains on. If the amber
parking brake warning light remains
on, see your dealer.
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.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in ACC/
ACCESSORY or ON/RUN.
2. Apply and hold the brake
pedal.
3. Press the EPB switch
momentarily.
The EPB is released when the red
parking brake status light is off.
If the amber parking brake warning
light is on, release the EPB by
pressing and holding the EPB
switch. Continue to hold the switch
until the red parking brake 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.
Automatic EPB Release
Avoid rapid acceleration when the
EPB is applied, to preserve parking
brake lining life.
The EPB will automatically release
when the engine is running, the
transmission is placed into gear,
and an attempt is made to drive
away by pressing the accelerator
pedal.
If parking on a hill, or if the vehicle
is pulling a trailer, see Driving
