Electric Parking Brake - Cadillac XTS Owner's Manual

186 DRIVING AND OPERATING
a sudden obstacle, a computer senses
the wheels are slowing down. If one of
the wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure to
each wheel, as required, faster than
any driver could. This can help you
steer around the obstacle while
braking hard.
As the brakes are applied, the
computer keeps receiving updates on
wheel speed and controls braking
pressure accordingly.
Remember: ABS does not change the
time needed to get a foot up to the
brake pedal or always decrease
stopping distance. If you get too close
to the vehicle in front of you, there
will not be enough time to apply the
brakes if that vehicle suddenly slows
or stops. Always leave enough room
up ahead to stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold the
brake pedal down firmly and let ABS
work. You may hear the ABS pump or
motor operating and feel the brake
pedal pulsate. This is normal.
Braking in Emergencies
ABS allows you to steer and brake at
the same time. In many emergencies,
steering can help more than even the
very best braking.

Electric Parking Brake

The EPB switch is on the left side of
the instrument panel. The 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 red parking brake
status light and an amber parking
brake warning light. See Electric
Parking Brake Light 0 122 and Service
Electric Parking Brake Light 0 123.
There are also parking brake-related
Driver Information Center (DIC)
messages. See Brake System Messages
0 135. In case of insufficient electrical
power, the EPB cannot be applied or
released.
Before leaving the vehicle, check the
red parking brake status 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. Lift up the EPB switch
momentarily.
