Applying the Electric Parking
Brake When the Vehicle is Moving
WARNINGS
Applying the electric parking brake
while moving will result in use of the
anti-lock braking system. Do not use
the electric parking brake system when the
vehicle is moving unless the normal brake
system is unable to stop the vehicle.
With the exception of emergency
conditions (for example, the brake
pedal does not work or is blocked),
do not apply the electric parking brake
while the vehicle is moving. On bends, or
poor road surfaces or weather conditions,
emergency braking can cause the vehicle
to skid out of control or off the road.
If you apply the electric parking brake when
your vehicle is moving, the brake system
warning lamp will illuminate and a warning
tone will sound. See Information
Displays (page 105).
If your vehicle speed is above 4 mph
(6 km/h), the braking force is applied as
long as the switch is pulled. Release or
press the switch or press the accelerator
pedal to stop the braking force.
Releasing the Electric Parking
Brake
E169086
You can release the electric parking brake
either manually by pressing the switch or
automatically.
Manual Release
WARNING
If the brake system warning light
remains illuminated or flashes after
you have released the parking brake,
there could be a problem with your braking
system. Have the system checked by an
authorized dealer as soon as possible.
You can manually release the electric
parking brake by:
1. Switching the ignition on.
2. Pressing the brake pedal.
3. Pressing the electric parking brake
switch.
When the electric parking brake is released,
the brake system warning lamp will turn
off.
Driving With a Trailer
Depending on the grade and the weight of
the trailer, your vehicle and trailer may roll
backwards slightly when you start on a
slope.
