remote start feature, the climate
control system may run when the
vehicle is started remotely. The system
will use the defrost setting if it is cold
outside or turn on using the coldest
setting if it is hot outside. The rear
defog may come on during remote
start based on cold ambient
conditions. The rear defog indicator
light does not come on during a
remote start.
If equipped, the heated seats will turn
on if it is cold outside or the
ventilated seats will turn on if it is hot
outside. The heated and ventilated
seat indicator lights may not come on
during a remote start. If equipped, the
heated steering wheel will come on in
a remote start if it is cold outside. The
heated steering wheel indicator light
may not come on. See Remote Vehicle
Start 036 and Heated and Ventilated

DRIVING AND OPERATING 177
.Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer
and vehicle control can be affected
when traction is reduced by water,
snow, ice, gravel, or other material
on the road. Learn to recognize
warning clues —such as enough
water, ice, or packed snow on the
road to make a mirrored surface
— and slow down when you have
any doubt.
. Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting
to a lower gear. Any sudden
changes could cause the tires to
slide.
Remember: Antilock brakes help avoid
only the braking skid.
Driving on Wet Roads
Rain and wet roads can reduce vehicle
traction and affect your ability to stop
and accelerate. Always drive slower in
these types of driving conditions and
avoid driving through large puddles
and deep-standing or flowing water.
{Warning
Wet brakes can cause crashes. They
might not work as well in a quick
stop and could cause pulling to one
side. You could lose control of the
vehicle.
After driving through a large puddle
of water or a car/vehicle wash,
lightly apply the brake pedal until
the brakes work normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water can
build up under the vehicle's tires so
they actually ride on the water. This
can happen if the road is wet enough and you are going fast enough. When
the vehicle is hydroplaning, it has
little or no contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.
Allow extra following distance.
. Pass with caution.
. Keep windshield wiping equipment
in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper tread
depth. See Tires0281.
. Turn off cruise control.
. Activate All-Wheel Drive (AWD)
mode. See Driver Mode Control
0 205.

180 DRIVING AND OPERATING
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. SeeTraction Control/
Electronic Stability Control 0203.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you or
others could be injured. The vehicle
can overheat, causing an engine
compartment fire or other damage.
Spin the wheels as little as possible
and avoid going above 56 km/h
(35 mph).
Rocking the Vehicle to Get it Out
Turn the steering wheel left and right
to clear the area around the front
wheels. Turn off any traction system.
Shift back and forth between
R (Reverse) and a low forward gear,
spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears. Release
the accelerator pedal while shifting,
and press lightly on the accelerator pedal when the transmission is in
gear. Slowly spinning the wheels in
the forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out, see
Towing the Vehicle
0312.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can carry.
This weight is called the vehicle
capacity weight and includes the
weight of all occupants, cargo, and
all nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry, the Tire and
Loading Information label and the
Certification/Tire label.
{Warning
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR),
or either the maximum front or
rear Gross Axle Weight Rating
(GAWR). This can cause
systems to break and change
the way the vehicle handles.
This could cause loss of control
and a crash. Overloading can
also reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12017481) - 2019 - CRC - 11/5/18
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

Sport :Sport Mode improves vehicle
handling and acceleration on dry
pavement. When active, Sport Mode
modifies steering efforts, transmission
shifting, AWD torque, and suspension
tuning, if equipped. When in Sport
Mode, the AWD Mode indicator light
will be on.
AWD : AWD Mode provides drive
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.
When in AWD Mode, the AWD Mode
indicator light will be on.
Snow/Ice (FWD Vehicles Only) :
Snow/Ice Mode improves vehicle
acceleration on snow and ice covered
roads.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 0203. If a
collision alert occurs when cruise
control is activated, cruise control is
disengaged. See Forward Collision Alert
(FCA) System 0226. 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.

Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed and
following gap. Read this entire section
before using this system. The
following gap is the following time
between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control. ACC
uses camera and radar sensors. See
Radio Frequency Statement 0350.
If a vehicle is detected in your path,
ACC can apply acceleration or limited,
moderate braking to maintain the
selected following gap. To disengage
ACC, apply the brake. If ACC is controlling your vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates, the ACC may
automatically disengage. See
Traction
Control/Electronic Stability Control
0 203. When road conditions allow
ACC to be safely used, the ACC can be
turned back on.
ACC will not engage if the TCS or
StabiliTrak/ESC system is disabled.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver” in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0174.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
. On winding and hilly roads or
when the sensors are blocked
by snow, ice, or dirt. The
system may not detect a
vehicle ahead. Keep the entire
front of the vehicle clean.
. Visibility is low, such as in
fog, rain, or snow conditions.
ACC performance is limited
under these conditions.
. On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.

the first detent. For each press, the
vehicle goes about 1 km/h (1 mph)
slower.
. To decrease the vehicle speed in
larger increments, move the
thumbwheel down toward SET− to
the second detent. For each press,
the vehicle speed decreases to the
next 5 km/h (5 mph) mark on the
speedometer.
. To decrease speed while the
vehicle is stopped, move the
thumbwheel down toward SET−
until the desired set speed is
displayed.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 0126.
The increment value used depends on
the units displayed.
Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected. Press[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near.
When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD. The gap setting will
be maintained until it is changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See Forward Collision Alert
(FCA) System 0226. Alerting the Driver
With Head-Up Display
Without Head-Up Display
If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, six red
lights or the collision alert symbol on
the HUD, if equipped, will flash on the
windshield. Either eight beeps will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. See “Collision/Detection
Systems” underVehicle Personalization
