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.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/25/22
236 Driving and Operating
driving defensively is to wear
the seat belt. See Seat Belts
060.
.Assume that other road
users (pedestrians,
bicyclists, and other drivers)
are going to be careless and
make mistakes. Anticipate
what they may do and be
ready.
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
Impaired Driving
Death and injury associated
with impaired driving is a
global tragedy.
{Warning
Drinking alcohol or taking
drugs and then driving is
very dangerous. Your
reflexes, perceptions,
attentiveness, and judgment
can be affected by even a
(Continued)
Warning (Continued)
small amount of alcohol or
drugs. You can have a
serious—or even fatal —
collision if you drive after
drinking or taking drugs.
Do not drive while under the
influence of alcohol or drugs,
or ride with a driver who has
been drinking or is impaired
by drugs. Find alternate
transportation home; or if
you are with a group,
designate a driver who will
remain sober.
Control of a Vehicle
Braking, steering, and
accelerating are important
factors in helping to control a
vehicle while driving.
Braking
Braking action involves
perception time and reaction
time. Deciding to push the brake pedal is perception time.
Actually doing it is
reaction time.
Average driver reaction time is
about three-quarters of a
second. In that time, a vehicle
moving at 100 km/h (60 mph)
travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in
mind include:
.Keep enough distance
between you and the vehicle
in front of you.
.Avoid needless heavy
braking.
.Keep pace with traffic.
If the engine ever stops while
the vehicle is being driven,
brake normally but do not
pump the brakes. Doing so
could make the pedal harder
to push down. If the engine
stops, there will be some
power brake assist but it will
be used when the brake is
applied. Once the power assist

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/25/22
Driving and Operating 239
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.
Off-Road Driving
All-Wheel Drive vehicles can
be used for off-road driving.
Vehicles without All-Wheel
Drive and vehicles not
equipped with All Terrain (AT)
or On-Off Road (OOR) tires
must not be driven off-road
except on a level, solid
surface. To contact the tire
manufacturer for more
information about the original
equipment tires, see the
Limited Warranty and Owner
Assistance Information
manual.
Controlling the vehicle is the
key to successful off-road
driving. One of the best ways
to control the vehicle is to
control the speed.
{Warning
When driving off-road,
bouncing and quick changes
in direction can easily throw
you out of position. This
could cause you to lose
control and crash. You and
your passengers should
always wear seat belts.
Before Driving Off-Road
.Have all necessary
maintenance and service
work completed.
.Fuel the vehicle, fill fluid
levels, and check inflation
pressure in all tires, including
the spare, if equipped.
.Read all the information
about All-Wheel Drive
vehicles in this manual.
.Make sure all underbody
shields, if equipped, are
properly attached.
.Know the local laws that
apply to off-road driving. To gain more ground
clearance if needed, it may be
necessary to remove the front
fascia lower air dam. However,
driving without the air dam
reduces fuel economy.
Caution
Operating the vehicle for
extended periods without
the front fascia lower air
dam installed can cause
improper airflow to the
engine. Reattach the front
fascia air dam after off-road
driving.
Loading the Vehicle for
Off-Road Driving
{Warning
.Unsecured cargo on the
load floor can be tossed
about when driving over
rough terrain. You or your
passengers can be struck
by flying objects. Secure
the cargo properly.

16406251) - 2023 - CRC - 3/25/22
Driving and Operating 241
.Avoid turns that take the
vehicle across the incline of
the hill. Driving across an
incline puts more weight on
the downhill wheels which
could cause a downhill slide
or a rollover.
.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 and potentially
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.
.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.

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 0243.
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.
More frequent maintenance
service is required. See
Maintenance Schedule
0429.
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.

16406251) - 2023 - CRC - 3/25/22
244 Driving and Operating
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 Tires0376.
.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
(Continued)
Warning (Continued)
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.

Driving and Operating 245
Winter Driving
Driving on Snow or IceCaution
To avoid damage to the
wheels and brake
components, always clear
snow and ice from inside the
wheels and underneath the
vehicle before driving.
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
0 271.
.The 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) 0268.
.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
0273 and
All-Wheel Drive 0267.
Cold Weather Mode
In very low temperatures, a
cold weather message may
display on the Driver
Information Center (DIC). The
engine speed, transmission
shift patterns, and cabin fan
speed may operate differently
to enable the vehicle to warm
up quicker. You can manually
override the cabin fan speed in
cold weather mode.
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 Assistance. See
Roadside Assistance Program
0446. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.

246 Driving and Operating
{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:
.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(Continued)
Warning (Continued)
the fan speed to the
highest setting. See
“Climate Control Systems.”
For more information about
CO, see Engine Exhaust
0 260.
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. 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. See Traction Control/
Electronic Stability Control
0 271.
{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).
