Brake Assist; Hill Start Assist (Hsa) - Cadillac XT5 2017 Owner's Manual

194 DRIVING AND OPERATING
The EPB applies automatically when
shifting to P (Park) on a steep incline.
The EPB releases as soon as the
vehicle is shifted out of P (Park) and
the vehicle accelerates.
If the EPB fails to apply, the rear
wheels should be blocked to prevent
vehicle movement.
EPB Release
To release the EPB:
1. Place the ignition in ACC/
ACCESSORY or ON/RUN.
2. Apply and hold the brake pedal.
3. Press the EPB switch
momentarily.
The EPB is released when the red
handbrake status light is off.
If the amber parking brake warning
light is on, release the EPB by pressing
and holding the EPB switch. Continue
to hold the switch until the red
handbrake status light is off. If either
light stays on after release is
attempted, see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
Automatic EPB Release
Avoid rapid acceleration when the EPB
is applied, to preserve parking brake
lining life.
The EPB will automatically release
when the engine is running, the
transmission is placed into gear, and
an attempt is made to drive away by
pressing the accelerator pedal.
If parking on a hill, or if the vehicle is
pulling a trailer, see Driving
Characteristics and Towing Tips 0 226.

Brake Assist

The Brake Assist feature is designed to
assist the driver in stopping or
decreasing vehicle speed in emergency
driving conditions. This feature uses
the stability system hydraulic brake
control module to supplement the
power brake system under conditions
where the driver has quickly and

an attempt to quickly stop or slow
down the vehicle. The stability system
hydraulic brake control module
increases brake pressure at each
corner of the vehicle until the ABS
activates. Minor brake pedal pulsation
or pedal movement during this time is
normal and the driver should continue
to apply the brake pedal as the driving
situation dictates. The Brake Assist
feature will automatically disengage
when the brake pedal is released or
brake pedal pressure is quickly
decreased.

Hill Start Assist (HSA)

This vehicle has an HSA feature,
which may be useful when the vehicle
is stopped on a gradient sufficient
