Using the Electric Parking Brake In
An Emergency
WARNINGS
Applying the electric parking brake
while moving will result in the
engagement 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 is broken 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.
Note: Repeated use of the electric parking
brake to slow the vehicle while moving may
cause damage to the brake system.
If you apply the electric parking brake when
your vehicle is moving, the rear brake lights
turn on, the brake system warning lamp
illuminates and a warning tone sounds.
See Information Displays (page 109).
If your vehicle speed is above 4 mph
(6 km/h), the braking force is applied as
long as you pull the switch. Release or
press the switch or press the accelerator
pedal to stop the braking force.
