Electric Parking Brake
The Electric Parking Brake (EPB)
can always be activated, even if the
ignition is off. To prevent draining
the battery, avoid repeated cycles of
the EPB when the engine is not
running.
The system has a
Y
Electric
Parking Brake light and a
8
Service
Parking Brake light or message.
See
and
Service Electric Parking Brake Light
. There are also parking
brake-related Driver Information
Center (DIC) messages. In case of
insufficient electrical power, the EPB
cannot be applied or released.
Before leaving the vehicle, check for
the
Y
light to ensure that the
parking brake 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
Y
light will flash and then stay
on once the EPB is fully applied.
If the
Y
light flashes continuously,
then the EPB is only partially
applied, the vehicle is in Service
Mode, or there is a problem with the
EPB. A DIC message will display.
Release the EPB switch 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
Y
light is flashing. See your dealer.

If the
8

switch and hold it. Continue to hold
the switch until the
Y
light remains
on. If the
8
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.
The vehicle may automatically apply
the EPB in some situations when
the vehicle is not moving. This is
normal, and is done to periodically
check the correct operation of the
EPB system.
If the EPB fails to apply, block the
rear wheels to prevent vehicle
movement.
