210 DRIVING AND OPERATING
Before driving on a hill, assess the
steepness, traction, and obstructions.
If the terrain ahead cannot be seen,
get out of the vehicle and walk the hill
before driving further.
When driving on hills:
.Use a low gear and keep a firm grip
on the steering wheel.
.Maintain a slow speed.
.When possible, drive straight up or
down the hill.
.Slow down when approaching the
top of the hill.
.Use headlamps even during the day
to make the vehicle more visible.
{Warning
Driving to the top of a hill at high
speed can cause a crash. There
could be a drop-off, embankment,
cliff, or even another vehicle. You
could be seriously injured or killed.
As you near the top of a hill, slow
down and stay alert.
.Never go downhill forward or
backward with the transmission in
N (Neutral). The brakes could
overheat and you could lose control.
.When driving down a hill, keep the
vehicle headed straight down. Use a
low gear because the engine will
work with the brakes to slow the
vehicle and help keep the vehicle
under control.
{Warning
Heavy braking when going down a
hill can cause your brakes to
overheat and fade. This could cause
loss of control and you or others
could be injured or killed. Apply the
brakes lightly when descending a
hill and use a low gear to keep
vehicle speed under control.
If the vehicle stalls on a hill: 1. Apply the brakes to stop the vehicle, and then apply the parking
brake. 2. Shift into P (Park) and then restart
the engine.
.If driving uphill when the
vehicle stalls, shift to
R (Reverse), release the parking
brake, and back straight down.
.Never try to turn the vehicle
around. If the hill is steep
enough to stall the vehicle, it is
steep enough to cause it to
roll over.
.If you cannot make it up the
hill, back straight down the hill.
.Never back down a hill in
N (Neutral) using only the
brake.
.The vehicle can roll backward
quickly and you could lose
control.
.If driving downhill when the
vehicle stalls, shift to a lower
gear, release the parking brake,
and drive straight down the hill.
3. If the vehicle cannot be restarted after stalling, set the parking brake,
shift the transmission into P (Park),
and turn the vehicle off.

DRIVING AND OPERATING 213
.Pass with caution.
.Keep windshield wiping equipment
in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper tread
depth. SeeTires0308.
.Turn off cruise control.
.Activate All-Wheel Drive (AWD)
mode. See Driver Mode Control
0 236.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving on
flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the vehicle
on a long downhill slope can cause
brake overheating, can reduce brake
performance, and could result in a
loss of braking. Shift the
transmission to a lower gear to let
the engine assist the brakes on a
steep downhill slope.
{Warning
Coasting downhill in N (Neutral) or
with the ignition off is dangerous.
This can cause overheating of the
brakes and loss of steering assist.
Always have the engine running
and the vehicle in gear.
.Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the center line.
.Be alert on top of hills; something
could be in your lane (e.g., stalled
car, crash).
.Pay attention to special road signs
(e.g., falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
.Select All-Wheel Drive (AWD) Mode.
See Driver Mode Control 0236 and
All-Wheel Drive 0232.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the
road creates less traction or grip, so
drive carefully. Wet ice can occur at
about 0 °C (32 °F) when freezing rain
begins to fall. Avoid driving on wet ice
or in freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick.
.Turn on Traction Control. See
Traction Control/Electronic Stability
Control 0235.

Cadillac XT4 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14584367) - 2021 - CRC - 10/14/20
DRIVING AND OPERATING 215
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 0235.
{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).
Select All-Wheel Drive (AWD) Mode.
See Driver Mode Control 0236 and
All-Wheel Drive 0232.
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
0345.
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
performance, damage the tires,
and shorten the life of the
vehicle.

Warning (Continued)
systems and disable the airbags.
While driving, only shut the vehicle
off in an emergency.
If the vehicle must be shut off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the brakes
repeatedly. This may deplete power
assist, requiring increased brake
pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle
is moving. After shifting to
N (Neutral), firmly apply the brakes
and steer the vehicle to a safe
location.
3. Come to a complete stop and shift to P (Park).
4. Set the parking brake. See Electric
Parking Brake 0233. Press ENGINE
START/STOP to turn the
vehicle off. If the vehicle cannot be pulled over
and must be shut off while driving,
press and hold ENGINE START/STOP
for longer than two seconds, or press
twice in five seconds.
ACC/ACCESSORY (Amber Indicator
Light) :
This mode allows you to use
some electrical accessories when the
engine is off.
With the ignition off, pressing
ENGINE START/STOP once without
the brake pedal applied will place the
ignition system in ACC/ACCESSORY.
The ignition will switch from ACC/
ACCESSORY to OFF after 10 minutes
to prevent battery rundown.
ON/RUN/START (Green Indicator
Light) : This mode is for driving and
starting. With the ignition off and the
brake pedal applied, pressing ENGINE
START/STOP once will place the
ignition system in ON/RUN/START.
Once engine cranking begins, release
the button. Engine cranking will
continue until the engine starts. The

14584367) - 2021 - CRC - 10/14/20
DRIVING AND OPERATING 221
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If you add electrical parts or
accessories, you could change the
way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty. See
Add-On Electrical Equipment0280.
To start the vehicle: 1. With the Keyless Access system, the RKE transmitter must be in the
vehicle. Press ENGINE START/
STOP with the brake pedal applied.
When the engine begins cranking,
let go of the button. The idle speed
will go down as the engine warms
up. Do not race the engine
immediately after starting it. If the RKE transmitter is not in the
vehicle, if there is interference, or if
the RKE battery is low, a Driver
Information Center (DIC) message
will display. See
Remote Keyless
Entry (RKE) System Operation 07.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP immediately
after cranking has ended, can
overheat and damage the cranking
motor, and drain the battery. Wait
at least 15 seconds between each
try, to let the cranking motor
cool down.
2. If the engine does not start after five to 10 seconds, especially in
very cold weather (below −18 °C or
0 °F), it could be flooded with too
much gasoline. Try pushing the
accelerator pedal all the way to the
floor and hold it there, then press
ENGINE START/STOP for up to a
maximum of 15 seconds. Wait at
least 15 seconds between each try,
to allow the cranking motor to cool
down. When the engine starts, let go of the button and the
accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra
gasoline from the engine. Do not
race the engine immediately after
starting it. Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Stop/Start System
The Stop/Start system will shut off
the engine to help conserve fuel.
It has components designed for the
increased number of starts.
{Warning
The automatic engine Stop/Start
feature causes the engine to shut
off while the vehicle is still on. Do
not exit the vehicle before shifting
to P (Park). The vehicle may restart
and move unexpectedly. Always
shift to P (Park), and then turn the
ignition off before exiting the
vehicle.
