Trailer Towing
Caution
Towing a trailer improperly can
damage the vehicle and result in
costly repairs not covered by the
vehicle warranty. To tow a trailer
correctly, follow the directions in
this section and see your dealer for
important information about
towing a trailer with the vehicle.
Trailer Weight
{Warning
Never exceed the towing capacity
for your vehicle. Safe trailering requires monitoring the
weight, speed, altitude, road grades,
outside temperature, dimensions of
the front of the trailer, and how
frequently the vehicle is used to tow a
trailer.
Trailer Weight Ratings
When towing a trailer, the combined
weight of the vehicle, vehicle contents,
trailer, and trailer contents must be
below all of the maximum weight
ratings for the vehicle, including:
.
GCWR: Gross Combined Weight
Rating
. GVWR: Gross Vehicle Weight
Rating
. Maximum Trailer Weight Rating
. Maximum Trailer Tongue Weight
Rating
The only way to be sure the weight is
not exceeding any of these ratings is
to weigh the tow vehicle and trailer
combination, fully loaded for the trip,
getting individual weights for each of
these items.
{Warning
You and others could be seriously
injured or killed if the trailer is too
heavy or the trailer brakes are
inadequate for the load. The vehicle
may be damaged, and the repairs
would not be covered by the vehicle
warranty.
Only tow a trailer if all the steps in
this section have been followed. Ask
your dealer for advice and
information about towing a trailer.
Gross Combined Weight
Rating (GCWR)
GCWR is the total allowable weight of
the completely loaded vehicle and
trailer including any fuel, passengers,
cargo, equipment, and accessories. Do
not exceed the GCWR for your vehicle.
The GCWR for the vehicle is on the
Tow Rating Chart following.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12146119) - 2019 - crc - 7/27/18
DRIVING AND OPERATING 245
To check that the weight of the
vehicle and trailer are within the
GCWR for the vehicle, follow these
steps:
.Start with the “curb weight”fro the
Trailering Information Label
. Add the weight of the trailer
loaded with cargo and ready for
the trip
. Add the weight of all passengers
. Add the weight of all cargo in the
vehicle
. Add the weight of hitch hardware
such as a draw bar, ball, load
equalizer bars, or sway bars
. Add the weight of any accessories
or aftermarket equipment added
to the vehicle
The resulting weight cannot exceed
the GCWR value shown on the
Trailering Information Label.
The gross combined weight can also
be confirmed by weighing the truck
and trailer on a public scale. The truck
and trailer should be loaded for the
trip with passengers and cargo.
Gross Vehicle Weight
Rating (GVWR)
For information about the vehicle's
maximum load capacity, see Vehicle
Load Limits 0183. When calculating
the GVWR with a trailer attached, the
trailer tongue weight must be
included as part of the weight the
vehicle is carrying.
Maximum Trailer Weight Rating
The maximum trailer weight rating is
calculated assuming the tow vehicle
has a driver, a front seat passenger,
and all required trailering equipment.
This value represents the heaviest
trailer the vehicle can tow, but it may
be necessary to reduce the trailer
weight to stay within the GCW,
GVWR, maximum trailer tongue load,
or GAWR-RR for the vehicle.
Use the tow rating chart to determine
how much the trailer can weigh, based
on the vehicle model, powertrain and
trailering options.

*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer
including any passengers, cargo, equipment, and conversions. The GCWR for the vehicle should not be exceeded.
Maximum Trailer Tongue Weight
Rating
The Maximum Trailer Tongue Weight
Rating is the allowable trailer tongue
weight that the vehicle can support
using a conventional trailer hitch.
It may be necessary to reduce the
overall trailer weight to stay within
the maximum trailer tongue weight
rating while still maintaining the
correct trailer balance.
Do not exceed a maximum trailer
tongue weight of 204 kg (450 lb).
The trailer tongue weight contributes
to the Gross Vehicle Weight (GVW).
GVW includes the CURB WEIGHT of
your vehicle, any passengers, cargo, equipment and the trailer tongue
weight. Vehicle options, passengers,
cargo, and equipment reduce the
maximum allowable tongue weight
the vehicle can carry, which also
reduces the maximum allowable
trailer weight.
Trailer Load Balance
The correct trailer load balance must
be maintained to ensure trailer
stability. Incorrect load balance is a
leading cause of trailer sway.

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12146119) - 2019 - crc - 7/27/18
DRIVING AND OPERATING 247
The trailer tongue weight (1) should
be 10–15% of the loaded trailer
weight (2). Some specific trailer types,
such as boat trailers, fall outside of
this range. Always refer to the trailer
owner’s manual for the recommended
trailer tongue weight for each trailer.
Never exceed the maximum loads for
your vehicle, hitch and trailer.
After loading the trailer, separately
weigh the trailer and then the trailer
tongue and calculate the trailer load
balance percentage to see if the
weights and distribution are
appropriate for your vehicle. If the
trailer weight is too high, it may be
possible to transfer some of the cargointo your vehicle. If the trailer tongue
weight is too high or too low, it may
be possible to rearrange some of the
cargo inside of the trailer.
Do not exceed the maximum
allowable tongue weight for your
vehicle. Use the shortest hitch
extension available to position the
hitch ball closer to your vehicle. This
will help reduce the effect of the
trailer tongue weight on the trailer
hitch and rear axle.
If a cargo carrier is used in the trailer
hitch receiver, choose a carrier that
positions the load as close to the
vehicle as possible. Make sure the
total weight, including the carrier, is
no more than half of the maximum
allowable tongue weight for the
vehicle or 227 kg (500 lb), whichever
is less.
Ask your dealer for trailering
information or assistance.
Towing Equipment
Hitches
Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going by, and
rough roads can affect the trailer and
the hitch.
Never attach rental hitches or other
bumper-type hitches. Only use
frame-mounted hitches that do not
attach to the bumper.
Always seal any holes in your vehicle
if the trailer hitch is removed. If not
sealed, dirt, water, and carbon
monoxide (CO) from the exhaust may
enter your vehicle. See
Engine Exhaust
0 194.

Hitch Cover
To remove hitch cover, if equipped:1. Remove the two fasteners on the lower tabs.
2. Pull the lower edge of the cover to about a 45 degree angle.
3. Pull the cover downward to disengage the upper
attachments. To reinstall hitch cover:
1. Hold cover at a 45 degree angle to the vehicle and push the
upper tabs into the slots in the
bumper.
2. Push the bottom of the cover forward until the lower tabs line
up with the lower slots.
3. Snap the hitch cover into place by pushing the upper corners
forward.
4. Reinstall the two fasteners on the lower tabs.
Consider using mechanical sway
controls with any trailer. Ask a
trailering professional about sway
controls or refer to the trailer
manufacturer's recommendations and
instructions.
Weight-Distributing Hitch
Adjustment
1. Front of Vehicle
2. Body to Ground Distance
When using a weight-distributing
hitch, measure the front fender height
distance (2) before connecting the
trailer. Adjust the spring bars until the
front fender height distance (2) is the
same height before the trailer was
connected. Do not reduce the front
fender height below the initial
distance (2).

Tires
.Do not tow a trailer while using a
compact spare tire on the vehicle.
. Tires must be properly inflated to
support loads while towing a
trailer. See Tires0284 for
instructions on proper tire
inflation.
Safety Chains
Always attach chains between the
vehicle and the trailer, and attach the
chains to the holes on the trailer hitch
platform. Instructions about safety
chains may be provided by the hitch
manufacturer or by the trailer
manufacturer.
Cross the safety chains under the
tongue of the trailer to help prevent
the tongue from contacting the road if
it becomes separated from the hitch.
Always leave just enough slack so the
combination can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
Loaded trailers over 450 kg (1,000 lb)
must be equipped with brake systems
and with brakes for each axle. Trailer
braking equipment conforming to
Canadian Standards Association (CSA)
requirement CAN3-D313, or its
equivalent, is recommended.
State or local regulations may require
trailers to have their own braking
system if the loaded weight of the
trailer exceeds certain requirements
that can vary from state to state.
Read and follow the instructions for
the trailer brakes so they are installed,
adjusted, and maintained properly.
Never attempt to tap into your
vehicle's hydraulic brake system.
If you do, both the vehicle anti-lock
brakes and the trailer brakes may not
function and could result in a crash.
Trailer Wiring
The trailer wiring harness (if
equipped), with a 7-pin connector is
located at the rear of the vehicle, and
it is tied to the vehicle's frame.
If the vehicle is not equipped with a
7-pin trailer connector, the body
harness has provisions to connect a
trailer harness and a 7-pin trailer
connector which is available through
your dealer.
Use only a round, seven-wire
connector with flat blade terminals
meeting SAE J2863 specifications for
proper electrical connectivity.

determine wire color coding of the
electric trailer brake controller. The
wire colors on the brake controller
may be different from the vehicle. The
electric trailer brake controller should
be installed by your dealer or a
qualified service center.
If equipped, there are four blunt cut
wires inside the front driver side
instrument panel. It will be necessary
to have a technician connect the
12-volt power to the engine
compartment fuse block.
Trailer Lamps
Always check all trailer lamps are
working at the beginning of each trip,
and periodically on longer trips.
Turn Signals When Towing a
Trailer
When properly connected, the trailer
turn signals will illuminate to indicate
the vehicle is turning, changing lanes,
or stopping. When towing a trailer,
the arrows on the instrument cluster
will illuminate even if the trailer is not
properly connected or the bulbs are
burned out.
Always check all trailer lamps are
working at the beginning of each trip,
and periodically on longer trips.
Trailer Sway Control (TSC)
Vehicles with StabiliTrak/Electronic
Stability Control (ESC) have a Trailer
Sway Control (TSC) feature. Trailer
sway is unintended side-to-side
motion of a trailer while towing. If the
vehicle is towing a trailer and the TSC
detects that sway is increasing, the
vehicle brakes are selectively applied
at each wheel, to help reduce
excessive trailer sway. If equipped with
the Integrated Trailer Brake Control

Cadillac XT5 Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
12146119) - 2019 - crc - 7/27/18
DRIVING AND OPERATING 251
(ITBC) system, and the trailer has an
electric brake system, StabiliTrak/ESC
may also apply the trailer brakes.
If TSC is enabled, the Traction Control
System (TCS)/StabiliTrak/ESC warning
light will flash on the instrument
cluster. Reduce vehicle speed by
gradually removing your foot from the
accelerator. If trailer sway continues,
StabiliTrak/ESC can reduce engine
torque to help slow the vehicle. TSC
will not function if StabiliTrak/ESC is
turned off. SeeTraction Control/
Electronic Stability Control 0205.
{Warning
Trailer sway can result in a crash
and in serious injury or death, even
if the vehicle is equipped with TSC.
(Continued)
Warning (Continued)
If the trailer begins to sway, reduce
vehicle speed by gradually removing
your foot from the accelerator. Then
pull over to check the trailer and
vehicle to help correct possible
causes, including an improperly or
overloaded trailer, unrestrained
cargo, improper trailer hitch
configuration, or improperly
inflated or incorrect vehicle or
trailer tires. SeeTowing Equipment
0 247 for trailer ratings and hitch
setup recommendations.
Trailer Tires
Special Trailer (ST) tires differ from
vehicle tires. Trailer tires are designed
with stiff sidewalls to help prevent
sway and to support heavy loads.
These features can make it difficult to
determine if the trailer tire pressures
are low only based on a visual
inspection. Always check all trailer tire pressures
before each trip when the tires are
cool. Low trailer tire pressure is a
leading cause of trailer tire blow-outs.
Trailer tires deteriorate over time. The
trailer tire sidewall will show the week
and year the tire was manufactured.
Many trailer tire manufacturers
recommend replacing tires more than
six years old.
Overloading is another leading cause
of trailer tire blow-outs. Never load
your trailer with more weight than the
tires are designed to support. The load
rating is located on the trailer tire
sidewall.
Always know the maximum speed
rating for the trailer tires before
driving. This may be significantly
lower than the vehicle tire speed
rating. The speed rating may be on
the trailer tire sidewall. If the speed
rating is not shown, the default trailer
tire speed rating is 105 km/h
(65 mph).
