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.

Caution
Overloading the vehicle may
cause damage. Repairs
would not be covered by the
vehicle warranty. Do not
overload the vehicle.
{Warning
Things inside the vehicle
can strike and injure
people in a sudden stop
or turn, or in a crash.
.Put things in the cargo
area of the vehicle. In
the cargo area, put
them as far forward as
possible. Try to spread
the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so
that some of them are
above the tops of the
seats.

Warning (Continued)
.Do not leave an
unsecured child
restraint in the vehicle.
.Secure loose items in
the vehicle.
.Do not leave a seat
folded down unless
needed.
Starting and
Operating
New Vehicle Break-In
Caution
The vehicle does not need
an elaborate break-in. But it
will perform better in the
long run if you follow these
guidelines:
.Do not drive at any one
constant speed, fast or
slow, for the first 800 km
(500 mi). Do not make (Continued)
Caution (Continued)
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
.Avoid making hard stops
for the first 300 km
(200 mi) or so. During this
time the new brake linings
are not yet broken in. Hard
stops with new linings can
mean premature wear and
earlier replacement.
Follow this breaking-in
guideline every time you
get new brake linings.
.Do not tow a trailer during
break-in. See Trailer
Towing0326 for the
trailer towing capabilities
of the vehicle and more
information.
Following break-in, engine
speed and load can be
gradually increased.
On new vehicles, the various
mechanical and electrical
systems experience a

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
16406251) - 2023 - CRC - 3/25/22
324 Driving and Operating
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive
as the vehicle itself. Get used
to the handling and braking of
the combination by driving on
a level road surface before
driving on public roads.
The trailer structure, the tires,
and the brakes must be all be
rated to carry the intended
cargo. Inadequate trailer
equipment can cause the
combination to operate in an
unexpected or unsafe manner.
Before driving, inspect all
trailer hitch parts and
attachments, safety chains,
electrical connectors, lamps,
tires, and mirrors. See Towing
Equipment0331. If the trailer
has electric brakes, start the
combination moving and then
manually apply the trailer
brake controller to check the
trailer brakes work. During the
trip, occasionally check that the cargo and trailer are
secure and that the lamps and
any trailer brakes are working.
Towing with a Stability
Control System
When towing, the stability
control system might be
heard. The system reacts to
vehicle movement caused by
the trailer, which mainly occurs
during cornering. This is
normal when towing heavier
trailers.
Following Distance
Stay at least twice as far
behind the vehicle ahead as
you would when driving
without a trailer. This can help
to avoid heavy braking and
sudden turns.
Passing
More passing distance is
needed when towing a trailer.
The combination of the vehicle
and trailer will not accelerate
as quickly and is much longer
than the vehicle alone. It is
necessary to go much farther
beyond the passed vehicle
before returning to the lane.
Pass on level roadways. Avoid
passing on hills if possible.
Backing Up
Hold the bottom of the
steering wheel with one hand.
To move the trailer to the left,
move that hand to the left. To
move the trailer to the right,
move that hand to the right.
Always back up slowly and,
if possible, have someone
guide you.

Warning (Continued)
When replacing wheels, use
a new GM original
equipment wheel.
Caution
The wrong wheel can also
cause problems with bearing
life, brake cooling,
speedometer or odometer
calibration, headlamp aim,
bumper height, vehicle
ground clearance, and tire or
tire chain clearance to the
body and chassis.
Tire Chains
{Warning
If the vehicle has 235/
55R20h size tires, do not
use tire chains. There is not
enough clearance. Tire
chains used on a vehicle
without the proper amount(Continued)
Warning (Continued)
of clearance can cause
damage to the brakes,
suspension, or other vehicle
parts. The area damaged by
the tire chains could cause
loss of control and a crash.
Use another type of traction
device only if its
manufacturer recommends
it for the vehicle's tire size
combination and road
conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage,
drive slow and readjust or
remove the traction device if
it contacts the vehicle. Do
not spin the wheels. If
traction devices are used,
install them on the front
tires.
Caution
If the vehicle is equipped
with a tire size other than
235/55R20, use tire chains
only where legal and only
when necessary. Use low
profile chains that add no
more than 12 mm thickness
to the tire tread and inner
sidewall. Use chains that are
the proper size for the tires.
Install them on the tires of
the front axle. Do not use
chains on the tires of the
rear axle. Tighten them as
tightly as possible with the
ends securely fastened.
Drive slowly and follow the
chain manufacturer's
instructions. If the chains
contact the vehicle, stop and
retighten them. If the
contact continues, slow
down until it stops. Driving
too fast or spinning the
wheels with chains on will
damage the vehicle.

Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time
could result in loss of
braking and handling. This
could lead to a crash and
you or others could be
injured. Use only one
compact spare tire at a time.
If this vehicle has a compact
spare tire, it was fully inflated
when new; however, it can
lose air over time. Check the
inflation pressure regularly.
It should be 420 kPa (60 psi).
Stop as soon as possible and
check that the spare tire is
correctly inflated after being
installed on the vehicle. The
compact spare tire is designed
