Active Fuel Management
This vehicle's engine may be equipped
with Active Fuel Management, which
allows the engine to operate on either all of its cylinders, or in reduced
cylinder operation, depending on the
driving conditions.
When less power is required, such as
cruising at a constant vehicle speed,
the system will operate in reduced
operation mode, allowing the vehicle
to achieve better fuel economy. When
greater power demands are required,
such as accelerating from a stop,
passing, or merging onto a freeway,

DRIVING AND OPERATING 201
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 noise or feel
vibration while the ABS is operating.
This is normal. The TCS/StabiliTrak/
ESC indicator light will flash to notify
the driver ABS is active and the ABS
ACTIVE message will display. ABS
activating may be an indication of aslippery road surface. Caution and
braking sooner may be required for
driving conditions.
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 vehicle has an Electric Parking
Brake (EPB). The EPB can always be
activated, even if the ignition is off. To
prevent draining the battery, avoid
repeated cycles of the EPB system
when the engine is not running.
The system has a
Yor PARK
Electric Parking Brake light, and
a
8Service Parking Brake light.
See Electric Parking Brake Light 0136
and Service Electric Parking Brake Light
0 136.
Before leaving the vehicle, check for
the
Yor PARK 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. Press the EPB switch momentarily.
The
Yor PARK light will flash and
then stay on once the EPB is fully
applied. If the
Yor PARK 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

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12017481) - 2019 - CRC - 11/5/18
202 DRIVING AND OPERATING
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
Yor PARK light is
flashing. See your dealer. See Electric
Parking Brake Light 0136.
If the
8light is on, press the EPB
switch and hold it. Continue to hold
the switch until the
Yor PARK light
remains on. If the
8light remains on,
see your dealer.
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 is done to periodically check the
correct operation of the EPB system.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:
1. Turn the ignition on or to ACC/ ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the
Yor
PARK light is off.
If the
8light is on, release the EPB by
pressing and holding the EPB switch.
Continue to hold the switch until
the
Yor PARK 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
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive
away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life.
If parking on a hill, or if the vehicle is
pulling a trailer, see Driving
Characteristics and Towing Tips 0240.
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 Electronic Brake Control Module
(EBCM), which controls the hydraulic
brake circuits to detect when the
driver has quickly and forcefully
applied the brake pedal in an attempt
to quickly stop or slow down the
vehicle and to provide additional
braking beyond a normal brake pedal
apply. The EBCM increases brake
pressure at each corner of the vehicle
until the ABS activates. Minor ABS
noise during this time is normal and

12017481) - 2019 - CRC - 11/5/18
DRIVING AND OPERATING 215
addition, the left and right sides of the
Safety Alert Seat will pulse three
times, or three beeps will sound. See
”Alert Type”and “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 149.
When the vehicle ahead drives away,
move the thumbwheel up toward
RES+ or press the accelerator pedal to
resume cruise control. If stopped for
more than two minutes or if the driver
door is opened and the driver seat belt
is unbuckled, the ACC automatically
applies the Electric Parking Brake
(EPB) to hold the vehicle. The EPB
status light will turn on. See Electric
Parking Brake 0201. To release the
EPB, press the accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0148.{Warning
If ACC has stopped the vehicle, and
if ACC is disengaged, turned off,
or canceled, the vehicle will no
longer be held at a stop. The vehicle
can move. When ACC is holding the
vehicle at a stop, always be
prepared to manually apply the
brakes.
{Warning
Leaving the vehicle without placing
it in P (Park) can be dangerous. Do
not leave the vehicle while it is
being held at a stop by ACC. Always
place the vehicle in P (Park) and
turn off the ignition before leaving
the vehicle.
ACC Override
If using the accelerator pedal while
ACC is active, the ACC indicator turns
blue on the instrument cluster and in
the HUD (if equipped) to indicate that automatic braking will not occur. ACC
will resume operation when the
accelerator pedal is not being pressed.
{Warning
The ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
Curves in the Road
{Warning
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle
accelerates up to the set speed,
especially when following a vehicle
exiting or entering exit ramps. You
could lose control of the vehicle or
crash. Do not use ACC while driving
on an entrance or exit ramp. Always
be ready to use the brakes if
necessary.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12017481) - 2019 - CRC - 11/5/18
DRIVING AND OPERATING 217
Do not use ACC when driving on steep
hills or when towing a trailer. ACC will
not detect a vehicle in the lane while
driving on steep hills. The driver will
often need to take over acceleration
and braking on steep hills, especially
when towing a trailer. If the brakes are
applied, the ACC disengages.
Disengaging ACC
There are three ways to
disengage ACC:
.Step lightly on the brake pedal.
. Press
