Driving and Operating
EPB Apply
The EPB can be applied any time
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the EPB switch. Once fully applied,
the parking brake status light will be
on. While the brake is being applied,
the status light will flash until full
apply is reached. If the light does
not come on, or remains flashing,
you need to have the vehicle
serviced. Do not drive the vehicle
if the parking brake status light
is flashing. See your dealer. See
Electric Parking Brake Light on
page 5 20 for more information.
If the EPB is applied while the
vehicle is in motion, a chime will
sound, and the DIC message
RELEASE PARK BRAKE SWITCH
will be displayed. The vehicle will
decelerate as long as the switch is
held in the up position. Releasing
the EPB switch during the
deceleration will release the parking
brake. If the switch is held in the up
position until the vehicle comes to a
stop, the EPB will remain applied.
If the parking brake status light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
The DIC message SERVICE PARK
BRAKE will be displayed. If this light
flashes continuously, release the
EPB, and attempt to apply it again.
If this light continues to flash, do not
drive the vehicle. See your dealer.
If the parking brake warning light is
on, the EPB has detected an error
in another system and is operating
with reduced functionality. To apply
the EPB when this light is on, lift up
on the EPB switch and hold it in the
up position. Full application of the
parking brake by the EPB system
may take a longer period of time
than normal when this light is on.
Continue to hold the switch until the
parking brake status light remains
on. If the parking brake warning
light is on, see your dealer.
If the EPB fails to apply, the rear
wheels should be blocked to
prevent vehicle movement.

EPB Release
To release the EPB, place the
ignition in the ON/RUN position,
apply and hold the brake pedal,
and push down momentarily on
the EPB switch. If you attempt to
release the EPB without the brake
pedal applied, a chime will sound,
and the DIC message PRESS
BRAKE PEDAL TO RELEASE
PARK BRAKE will be displayed.
The EPB is released when the
parking brake status light is off.
If the parking brake warning light
is on, the EPB has detected an
error in another system and is
operating with reduced functionality.
To release the EPB when this light
is on, push down on the EPB switch
and hold it in the down position.
EPB release may take a longer
period of time than normal when
this light is on. Continue to hold the
switch until the parking brake status
light is off. If the light is on, see your
dealer.
