Electric Parking Brake - Chevrolet 2011 Volt Owner's Manual

9-32 Driving and Operating

Electric Parking Brake

The vehicle has an Electric Parking
Brake (EPB). The switch is on
the center stack. The EPB can
always be activated, even if the
vehicle is off. To prevent draining
the 12 volt battery, avoid repeated
cycles of the EPB system when the
vehicle is off.
In case of insufficient electrical
power, the EPB cannot be applied
or released.
Before leaving the vehicle, check
the Electric Parking Brake Light to
ensure the parking brake is applied.
EPB Apply
The EPB can be applied anytime
the vehicle is stopped. The EPB is
applied by momentarily lifting up on
the switch. Once fully applied,
the Electric Parking Brake Light will
be on. While the brake is being
applied, the Electric Parking Brake
Light will flash until full apply is
reached. If the light does not come
on, or remains flashing, have the
vehicle serviced. Do not drive the
vehicle if the Electric Parking Brake
Light is flashing. See your dealer.
If the EPB is applied while the
vehicle is in motion, a chime will
sound, and the DIC message
RELEASE PARKING BRAKE
will be displayed. The vehicle
will decelerate as long as the
switch is held in the up position.
Releasing the switch during
the deceleration will release the
parking brake. If the
held in the up position until the
vehicle comes to a stop, the EPB
will remain applied.
If the Electric Parking Brake Light
flashes continuously, the EPB is
only partially applied or released,
or there is a problem with the EPB.
The DIC message SERVICE
PARKING 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 Service Electric Parking Brake
Light is on, the EPB has detected a
system problem and is operating
with reduced functionality. To apply
the EPB when this light is on, lift up
on the 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.
