Driving Information
Driving for Better Fuel
Economy
Driving habits can affect fuel mileage.
Here are some driving tips to get the
best fuel economy possible.
.Set the climate controls to the
desired temperature after the engine
is started, or turn them off when
not required.
.On AWD vehicles, use Tour Mode
when conditions permit.
.Avoid fast starts and accelerate
smoothly.
.Brake gradually and avoid abrupt
stops.
.Avoid idling the engine for long
periods of time.
.When road and weather conditions
are appropriate, use cruise control.
.Always follow posted speed limits or
drive more slowly when conditions
require.
.Keep vehicle tires properly inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires with the
same TPC Spec number molded into
the tire's sidewall near the size.
.Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and
can take your focus from the task of
driving. Exercise good judgment and
do not let other activities divert your
attention away from the road. Many
local governments have enacted laws
regarding driver distraction. Become
familiar with the local laws in
your area.
To avoid distracted driving, keep your
eyes on the road, keep your hands on
the steering wheel, and focus your
attention on driving.
.Do not use a phone in demanding
driving situations. Use a hands-free
method to place or receive
necessary phone calls.
.Watch the road. Do not read, take
notes, or look up information on
phones or other electronic devices.
.Designate a front seat passenger to
handle potential distractions.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14590481) - 2021 - CRC - 10/22/20
DRIVING AND OPERATING 213
.Holding both sides of the steering
wheel allows you to turn
180 degrees without removing
a hand.
.The Antilock Brake System (ABS)
allows steering while braking.
Off-Road Recovery
The vehicle's right wheels can drop off
the edge of a road onto the shoulder
while driving. Follow these tips:1. Ease off the accelerator and then, if there is nothing in the way, steer
the vehicle so that it straddles the
edge of the pavement. 2. Turn the steering wheel about
one-eighth of a turn, until the right
front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
.Steering or Cornering Skid —too
much speed or steering in a curve
causes tires to slip and lose
cornering force.
.Acceleration Skid —too much
throttle causes the driving wheels
to spin.
Defensive drivers avoid most skids by
taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible. If the vehicle starts to slide, follow
these suggestions:
.Ease your foot off the accelerator
pedal and steer the way you want
the vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs.
.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 AND OPERATING 215
Environmental Concerns
.Always use established trails, roads,
and areas that have been set aside
for public off-road recreational
driving and obey all posted
regulations.
.Do not damage shrubs, flowers,
trees, or grasses or disturb wildlife.
.Do not park over things that burn.
SeeParking over Things That Burn
0 230.
Driving on Hills
Driving safely on hills requires good
judgment and an understanding of
what the vehicle can and cannot do.
{Warning
Many hills are simply too steep for
any vehicle. Driving up hills can
cause the vehicle to stall. Driving
down hills can cause loss of control.
Driving across hills can cause a
rollover. You could be injured or
killed. Do not drive on steep hills. 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.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14590481) - 2021 - CRC - 10/22/20
216 DRIVING AND OPERATING
2. Shift into P (Park) and then restartthe 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 into P (Park), and turn the
vehicle off. 3.1. Leave the vehicle and
seek help.
3.2. Stay clear of the path the vehicle would take if it rolled
downhill.
.Avoid turns that take the vehicle
across the incline of the hill. A hill
that can be driven straight up or
down might be too steep to drive
across. Driving across an incline
puts more weight on the downhill
wheels which could cause a
downhill slide or a rollover.
.Surface conditions can be a
problem. Loose gravel, muddy spots,
or even wet grass can cause the
tires to slip sideways, downhill.
If the vehicle slips sideways, it can
hit something that will trip it –a
rock, a rut, etc. –and roll over.
.Hidden obstacles can make the
steepness of the incline more
severe. If a rock is driven across
with the uphill wheels, or if the
downhill wheels drop into a rut or
depression, the vehicle can tilt
even more.
.If an incline must be driven across,
and the vehicle starts to slide, turn
downhill. This should help
straighten out the vehicle and
prevent the side slipping.
{Warning
Getting out of the vehicle on the
downhill side when stopped across
an incline is dangerous. If the
vehicle rolls over, you could be
crushed or killed. Always get out on
the uphill side of the vehicle and
stay well clear of the rollover path.
Driving in Mud, Sand, Snow,
or Ice
Use a low gear when driving in mud –
the deeper the mud, the lower the
gear. Keep the vehicle moving to avoid
getting stuck.
Traction changes when driving on
sand. On loose sand, such as on
beaches or sand dunes, the tires tend
to sink into the sand. This affects
steering, accelerating, and braking.
Drive at a reduced speed and avoid
sharp turns or abrupt maneuvers.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14590481) - 2021 - CRC - 10/22/20
DRIVING AND OPERATING 217
Traction is reduced on hard packed
snow and ice and it is easy to lose
control. Reduce vehicle speed when
driving on hard packed snow and ice.
{Warning
Driving on frozen lakes, ponds,
or rivers can be dangerous. Ice
conditions vary greatly and the
vehicle could fall through the ice;
you and your passengers could
drown. Drive your vehicle on safe
surfaces only.
Driving in Water
{Warning
Driving through rushing water can
be dangerous. Deep water can
sweep your vehicle downstream and
you and your passengers could
drown. If it is only shallow water, it
can still wash away the ground
from under your tires. Traction
could be lost, and the vehicle could
roll over. Do not drive through
rushing water.
Caution
Do not drive through standing
water if it is deep enough to cover
the wheel hubs, axles, or exhaust
pipe. Deep water can damage the
axle and other vehicle parts.
If the standing water is not too deep,
drive slowly through it. At faster
speeds, water splashes on the ignition
system and the vehicle can stall.
Stalling can also occur if you get the
exhaust pipe under water. While the
exhaust pipe is under water, you will
not be able to start the engine. When
going through water, the brakes get
wet, and it might take longer to stop.
See Driving on Wet Roads 0217.
After Off-Road Driving
Remove any brush or debris that has
collected on the underbody or chassis,
or under the hood. These
accumulations can be a fire hazard.
After operation in mud or sand, have
the brake linings cleaned and checked.
These substances can cause glazing
and uneven braking. Check the body
structure, steering, suspension, wheels, tires, and exhaust system for
damage and check the fuel lines and
cooling system for any leakage.
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

218 DRIVING AND OPERATING
Warning (Continued)
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. SeeTires0325.
.Turn off cruise control.
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, 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.
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

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14590481) - 2021 - CRC - 10/22/20
DRIVING AND OPERATING 219
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
Control0240.
.Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes should be
applied sooner than when on dry
pavement. See Antilock Brake System
(ABS) 0238.
.Allow greater following distance and
watch for slippery spots. Icy patches
can occur on otherwise clear roads
in shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
.Turn off cruise control.
.Select All-Wheel Drive (AWD) Mode
for vehicles equipped with AWD.
Select Snow/Ice Mode for FWD only
vehicles. See Driver Mode Control
0 242 and
All-Wheel Drive 0237.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby. If possible,
use Roadside Service. See Roadside
Service 0396. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside. Engine
exhaust contains carbon monoxide
(CO), which cannot be seen or
smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:
(Continued)
Warning (Continued)
.Clear snow from the base of the
vehicle, especially any blocking
the exhaust pipe.
.Open a window about 5 cm (2 in)
on the vehicle side that is away
from the wind, to bring in
fresh air.
.Fully open the air outlets on or
under the instrument panel.
.Adjust the climate control
system to circulate the air inside
the vehicle and set the fan speed
to the highest setting. See
“Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0231.
To save fuel, run the engine for short
periods to warm the vehicle and then
shut the engine off and partially close
the window. Moving about to keep
warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle speed.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14590481) - 2021 - CRC - 10/22/20
220 DRIVING AND OPERATING
This keeps the battery charged to
restart the vehicle and to signal for
help with the headlamps. Do this as
little as possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels
to free the vehicle when stuck in sand,
mud, ice, or snow.
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 0240.
{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).
For All-Wheel Drive (AWD), select
Off-Road or AWD mode. See Driver
Mode Control 0242 and
All-Wheel Drive 0237.
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 0361.
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.

DRIVING AND OPERATING 237
M (Manual Mode) can be exited to
return to D (Drive) at any speed by
pulling the lever rearward from the
center position. It is not necessary to
stop the vehicle or shift to N (Neutral)
or P (Park) prior to shifting back to
D (Drive).
Temporary Tap Shift Mode
To enter Temporary Tap Shift Mode:1. With the transmission in D (Drive) and not in Permanent Tap Shift
Mode, the Tap Shift controls will
activate a Temporary Tap Shift
Mode, allowing the transmission to
be manually shifted.
2. To deactivate, hold the right control briefly. Automatic shifts
return after no manual shifts have
been done for seven to 10 seconds.
While using Tap Shift, the vehicle will
have firmer, quicker shifting. This can
be used for sport driving or when
climbing or descending hills, to stay in
gear longer, or to downshift for more
power or engine braking.
The transmission will only allow
shifting into gears appropriate for the
vehicle speed and engine revolutions per minute (rpm). If shifting is
prevented for any reason, the M or D
will flash in the instrument cluster.
The transmission will not
automatically shift to the next higher
gear if the engine rpm is too high.
It will only automatically shift to the
next lower gear if the engine rpm is
much too low.
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate
in All-Wheel Drive (AWD) Mode. See
Driver Mode Control
0242.
Press MODE to activate AWD. AWD is
active in AWD, Sport, and Off-Road
Modes.
The AWD system delivers power to all
four wheels and the system adjusts as
needed to improve traction.
The AWD Mode will stay selected
until the mode is changed. If the
vehicle is placed in Sport Mode, see
Driver Mode Control 0242.
Sport Mode and Off-Road Mode are
canceled with each ignition cycle. See
Driver Mode Control 0242.
When operated in Tour Mode, the
vehicle will deliver power to the front
wheels only and may provide better
fuel economy.
If Tour Mode is selected see Driver
Mode Control 0242.
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
