Brakes
Electric Brake Boost
Vehicles equipped with
electric brake boost have
hydraulic brake circuits that
are electronically controlled
when the brake pedal is
applied during normal
operation. The system
performs routine tests and
turns off within a few minutes
after the vehicle is turned off.
Noise may be heard during
this time. If the brake pedal is
pressed during the tests or
when the electric brake boost
system is off, a noticeable
change in pedal force and
travel may be felt. This is
normal.
Antilock Brake
System (ABS)
The Antilock Brake System
(ABS) helps prevent a braking
skid and maintain steering
while braking hard.
If there is a problem with ABS,
this warning light stays on.
See Antilock Brake System
(ABS) Warning Light 0129.
ABS does not change the time
needed to get a foot on the
brake pedal and does not
always decrease stopping
distance. If you get too close
to the vehicle ahead, there will
not be enough time to apply
the brakes if that vehicle
suddenly slows or stops.
Always leave enough room
ahead to stop, even with ABS.
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

16412876) - 2023 - CRC - 3/25/22
Driving and Operating 265
The Electric Parking Brake
(EPB) can always be applied,
even if the vehicle is 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 service parking brake
warning light. See Electric
Parking Brake Light0129 and
Service Electric Parking Brake
Light 0129. There are also
parking brake-related Driver
Information Center (DIC)
messages.
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. Press the EPB switch
momentarily.
The red parking brake status
light will flash and then stay on
once the EPB is fully applied.
If the red parking brake 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 parking
brake status light is flashing.
See your dealer.
If the amber service parking
brake warning light is on,
press the EPB switch.
Continue to hold the switch
until the red parking brake
status light remains on. If the
amber service parking brake
warning light is 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, or at the request
of other safety functions that
utilize the EPB.
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 accessory mode.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16412876) - 2023 - CRC - 3/25/22
266 Driving and Operating
The EPB is released when the
red parking brake status light
is off.
If the amber service parking
brake warning light is on,
release the EPB by pressing
and holding the EPB switch.
Continue to hold the switch
until the red parking brake
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.
If you are towing a trailer and
parking on a hill, see Driving
Characteristics and Towing
Tips 0314.
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.
Brake Assist
Brake Assist detects rapid
brake pedal applications due
to emergency braking
situations and provides
additional braking to activate
the Antilock Brake System
(ABS) if the brake pedal is not
pushed hard enough to
activate ABS normally. Minor
noise, brake pedal pulsation,
and/or pedal movement during
this time may occur. Continue
to apply the brake pedal as
the driving situation dictates.
Brake Assist disengages when
the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA
feature. HSA does not
replace the need to pay
attention and drive safely.
You may not hear or feel
alerts or warnings provided
by this system. Failure to
use proper care when
driving may result in injury,
death, or vehicle damage.
See Defensive Driving 0230.
When the vehicle is stopped
on a grade, Hill Start Assist
(HSA) prevents the vehicle
from rolling in an unintended
direction during the transition
from brake pedal release to
accelerator pedal apply. The
brakes release when the
accelerator pedal is applied.
If the accelerator pedal is not
applied within a few minutes,
the Electric Parking Brake will
apply. The brakes may also

16412876) - 2023 - CRC - 3/25/22
Driving and Operating 267
release under other
conditions. Do not rely on HSA
to hold the vehicle.
HSA is available when the
vehicle is facing uphill in a
forward gear, or when facing
downhill in R (Reverse). The
vehicle must come to a
complete stop on a grade for
HSA to activate.
Ride Control
Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction
Control System (TCS) and
StabiliTrak/Electronic Stability
Control (ESC). These systems
help limit wheel spin and assist
the driver in maintaining
control, especially on slippery
road conditions.TCS activates if it senses that
any of the drive wheels are
spinning or beginning to lose
traction. On an All-Wheel Drive
(AWD) vehicle in AWD or Sport
Mode, the system will operate
if it senses that any of the
wheels are spinning or
beginning to lose traction.
When this happens, TCS
applies the brakes to the
spinning wheels and reduces
engine power to limit
wheel spin.
StabiliTrak/ESC activates
when the system senses a
discrepancy between the
intended path and the
direction the vehicle is actually
traveling. StabiliTrak/ESC
selectively applies braking
pressure at any one of the
vehicle's brakes to help steer
the vehicle in the direction
which you are steering.
If cruise control is being used
and traction control or
StabiliTrak/ESC begins to limit
wheel spin, cruise control willdisengage. Cruise control may
be turned back on when road
conditions allow. TCS and
StabiliTrak/ESC will
automatically turn on when
cruise control is set.
Both systems come on
automatically when the vehicle
is started and begins to move.
The systems may be heard or
felt while they are operating
or while performing diagnostic
checks. This is normal and
does not mean there is a
problem with the vehicle.
It is recommended to leave
both systems on for normal
driving conditions, but it may
be necessary to turn TCS off
if the vehicle gets stuck in
sand, mud, ice, or snow. See If
the Vehicle Is Stuck
0241 and
“Turning the Systems Off and
On” later in this section.

268 Driving and Operating
The indicator light for both
systems is in the instrument
cluster. This light will:
.Flash when TCS is limiting
wheel spin.
.Flash when StabiliTrak/ESC
is activated.
.Turn on and stay on when
either system is not working.
If either system fails to turn on
or to activate, a message may
display in the Driver
Information Center (DIC), and
dcomes on and stays on to
indicate that the system is
inactive and is not assisting
the driver in maintaining
control. The vehicle is safe to
drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle. 2. Turn the engine off and
wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes
on and stays on, the vehicle
may need more time to
diagnose the problem. If the
condition persists, see your
dealer.

Driver Mode Control
Driver Mode Control (DMC)
allows the driver to adjust the
overall driving experience to
better suit driver preference
by adjusting vehicle systems.
Drive mode availability and
affected vehicle systems are
dependent on vehicle trim
level, region, and optional
features. If the vehicle is in Tour or AWD
Mode, it will stay in that mode
through future ignition cycles.
If the vehicle is in any other
mode, it will return to Tour
Mode when the vehicle is
restarted. When a mode is
selected, an indicator will
come on in the instrument
cluster and stay on.
Driver Mode Control Switch
To activate each mode, press
the MODE button on the
center console. Tour Mode :
Use for normal
city and highway driving to
provide a smooth ride. This
setting provides balance
between comfort and
handling. This is the standard/
default mode. There is no
persistent indicator in the
instrument cluster for
this mode.
AWD Mode : AWD Mode
provides torque to all four
wheels. Select AWD to
improve traction and control
on slippery road surfaces,
such as gravel, sand, wet
pavement, snow, and ice. For
more information on AWD
Mode, see All-Wheel Drive
0 263.
Sport Mode : Use where road
conditions or personal
preference demand a more
controlled response. Sport
Mode improves vehicle
handling and acceleration on
dry pavement. When active,

16412876) - 2023 - CRC - 3/25/22
270 Driving and Operating
Sport Mode modifies steering
efforts, transmission shifting,
and AWD torque, if equipped.
The Performance Algorithm
Liftfoot (PAL) feature is
enabled in Sport Mode. PAL
allows the transmission to
hold the current gear after a
quick release of a heavily
applied accelerator pedal. This
provides greater engine
braking and enhanced vehicle
control.
When PAL is activated, there
may be an additional gear
symbol that appears in the
instrument cluster display. See
Performance Shifting Light
0130.
Off-Road Mode : Use this
mode for off-road recreational
driving. When active, Off–Road
Mode should be used to
improve driving at moderate
speeds, on grass, gravel, dirt,
unpaved roads,
or snow-covered roads. The
accelerator pedal is tuned for off-road use. This mode
modifies pedal mapping, AWD,
ESC, and TCS Performance.
Snow/Ice Mode :
Snow/Ice
Mode improves vehicle
acceleration on snow and ice
covered roads. When active,
Snow/Ice Mode will adjust
acceleration to optimize
traction on slippery surfaces.
This can compromise the
acceleration on dry asphalt.
This feature is not intended
for use when the vehicle is
stuck in sand, mud, ice, snow,
or gravel. If the vehicle
becomes stuck, see If the
Vehicle Is Stuck 0241.
Cruise Control
{
Warning
Cruise control can be
dangerous where you
cannot drive safely at a (Continued)
Warning (Continued)
steady speed. Do not use
cruise control on winding
roads or in heavy traffic.
Cruise control can be
dangerous on slippery roads.
On such roads, fast changes
in tire traction can cause
excessive wheel slip, and
you could lose control. Do
not use cruise control on
slippery roads.
With cruise control, a speed of
about 40 km/h (25 mph) or
more can be maintained
without keeping your foot on
the accelerator. Cruise control
does not work at speeds
below about 40 km/h (25 mph).

If the Traction Control System
(TCS) or StabiliTrak/Electronic
Stability Control (ESC) begins
to limit wheel spin while using
cruise control, the cruise
control automatically
disengages. See Traction
Control/Electronic Stability
Control0267. If a collision
alert occurs when cruise
control is activated, cruise
control is disengaged. See
Forward Collision Alert (FCA)
System 0297. When road
conditions allow cruise control
