Electric Parking Brake - Cadillac XT4 Owner's Manual

222 DRIVING AND OPERATING
Using ABS
Do not pump the brakes. Just hold the
brake pedal down firmly. Hearing and
feeling ABS operate is normal.
Braking in Emergencies
ABS allows steering and braking at the
same time. In many emergencies,
steering can help even more than
braking.

Electric Parking Brake

The Electric Parking Brake (EPB) can
always be applied, even if the vehicle
is switched off. In case of insufficient
electrical power, the EPB cannot be
applied or released. To prevent
draining the battery, avoid
unnecessary repeated cycles of
the EPB.
The system has a red parking brake
status light, and an amber parking
brake service warning light. See
Electric Parking Brake Light 0 108 and
Service Electric Parking Brake Light
0 108. There are also
handbrake-related Driver Information
Centre (DIC) messages.
Before leaving the vehicle, check the
red handbrake status light to ensure
that the handbrake 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 red handbrake status light will
flash and then stay on once the EPB is
fully applied. If the red handbrake
status light flashes continuously, then
the EPB is only partially applied or
there is a problem with the EPB.
A DIC message will display. Release
the EPB 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 red
handbrake status light is flashing. See
your dealer.
If the amber parking brake service
warning light is illuminated, press the
EPB switch. Continue to hold the
switch until the red handbrake status
light remains on. If the amber parking
brake service warning light is
illuminated, see your retailer.
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 takes place to periodically check
the correct operation of the EPB
system, or at the request of other
safety functions that utilise the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
