Driving and Operating 187
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. SeeAntilock Brake System
(ABS) Warning Light 0105. 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
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
Light 0104 and Service Electric Parking
Brake Light 0104. There are also parking
brake-related Driver Information Center (DIC)
messages.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17180837) - 2024 - CRC - 2/28/23
188 Driving and Operating
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.
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 0250.
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

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
17180837) - 2024 - CRC - 2/28/23
Driving and Operating 189
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. SeeDefensive Driving
0 164.
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 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 will disengage.
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 0169 and “Turning the
Systems Off and On” later in this section.

17180837) - 2024 - CRC - 2/28/23
190 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
d
comes 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

Cruise Control
{
Warning
Cruise control can be dangerous where
you cannot drive safely at a 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 Control. If a collision alert occurs
when cruise control is activated, cruise
control is disengaged. See Forward Collision Alert (FCA) System. When road conditions
allow cruise control to be safely used, it can
be turned back on.
Cruise control will disengage if either TCS or
StabiliTrak/ESC is turned off.
If the brakes are applied, cruise control
disengages.

the Head-Up Display (HUD), if equipped.
Resuming a Set Speed
If the cruise control is set at a desired speed
and then the brakes are applied or
*is
pressed, the cruise control is disengaged
without erasing the set speed from memory.
Once the vehicle speed reaches about
40 km/h (25 mph) or more, move the
thumbwheel up toward RES+ briefly. The
vehicle returns to the previous set speed.
Increasing Speed While Using Cruise Control
If the cruise control system is already
activated:
.Move the thumbwheel up toward RES+
until the desired speed is reached, then
release it.
.To increase vehicle speed in small
increments, move the thumbwheel up
toward RES+ briefly. For each press, the
vehicle goes about 1 km/h (1 mph) faster.
.To increase vehicle speed in larger
increments, move the thumbwheel up
toward RES+ to the second detent. For each press, the vehicle speed increases to
the next 5 km/h (5 mph) mark on the
speedometer.

Passing Another Vehicle While Using Cruise
Control
Use the accelerator pedal to increase the
vehicle speed. When you take your foot off
the pedal, the vehicle will slow down to the
previous set cruise speed.
While pressing the accelerator pedal or
shortly following the release to override
cruise, briefly moving the thumbwheel down
toward SET− will result in cruise set to the
current vehicle speed.
Using Cruise Control on Hills
How well the cruise control will work on
hills depends upon the vehicle speed, load,
and the steepness of the hills. When going
up steep hills, you might have to step on
the accelerator pedal to maintain your
speed. When going downhill, the cruise
control system may automatically brake to
slow the vehicle down. Also, you may have
to brake or shift to a lower gear to keep
your speed down. If the brake pedal is
applied, cruise control disengages. Ending Cruise Control
There are four ways to end cruise control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to N (Neutral).
.PressJ.
Erasing Speed Memory
The cruise control set speed is erased from
memory if
Jis pressed or if the ignition is
turned off.
Speed Limiter
If equipped, Speed Limiter allows you to set
a maximum speed limit. When Speed Limiter
is active at a set speed, it prevents the
vehicle from accelerating above the set
speed even if you continue to accelerate.
Speed Limiter can be used at speeds of
about 20 km/h (12 mph) or more. You can
temporarily override the set speed. See
“Overriding Speed Limiter” later in this
section.
Speed Limiter does not limit the vehicle
speed when driving down a hill. If the
vehicle speed exceeds the set speed when driving down a hill, beeps will sound to alert
you that the vehicle has exceeded the set
speed.
{Warning
Speed Limiter does not automatically
apply the brakes in emergency braking
situations. To avoid possible injury or
death, always be prepared to brake in
emergencies and pay careful attention to
the road ahead while driving.
Speed Limiter will automatically be
disabled if:
.Cruise control or Adaptive Cruise Control
(ACC) is turned on, if equipped.
.Super Cruise is turned on, if equipped.
Speed Limiter is controlled using the RES+
and SET− thumbwheel and the
*button on
the steering wheel:
RES+ : Move the thumbwheel up to resume
Speed Limiter at the last set speed in
memory, to increase the set speed (Manual
mode), or to increase the offset
(Auto mode).
