3. Add the weight of allpassengers.
4. Add the weight of all cargo in the vehicle.
5. Add the weight of hitch hardware such as a draw
bar, ball, load equalizer
bars, or sway bars.
6. 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 0252. 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
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 and 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 load balance.
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 XT6 Owner Manual (GMNA-Localizing-U.S./Canada-16405819) -
2023 - CRC - 3/22/22
Driving and Operating 355
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.
The trailer load
balance percentage is
calculated as: weight (1)
divided by weight (2)
times 100.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 cargo
into 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 the 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 totalweight, 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.
Rear Gross Axle Weight
Rating (GAWR-RR)
The GAWR-RR is the total
weight that can be supported
by the rear axle of the vehicle.
Do not exceed the GAWR-RR
for the vehicle, with the tow
vehicle and trailer fully loaded
for the trip including the
weight of the trailer tongue.
If using a weight-distributing
hitch, do not exceed the
GAWR-RR before applying the
weight distribution
spring bars.
For additional assistance with
trailering or additional
information, see your dealer.

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.
Hitch Cover
To remove the 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 the hitch cover: 1. Hold the 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
A weight-distributing hitch
may be useful with some
trailers.

2. Body to Ground Distance

Driving and Operating 357
When using a
weight-distributing hitch,
measure the front fender
height above the front axle
distance (2) before and after
connecting the trailer. Adjust
the spring bars until the front
fender height distance (2) is
approximately halfway
between the first and second
measurements.
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
Tires0400 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 trailerexceeds certain minimums
that can vary from state to
state.
Read and follow the
instructions for the trailer
brakes so they are installed,
adjusted, and maintained
properly.
{Warning
Never attempt to tamper
with the hydraulic brake
system for your trailer
brakes. Do not connect a
trailer's hydraulic brake
system directly to your
vehicle's hydraulic brake
system. If you do, both the
vehicle antilock brakes and
the trailer brakes may not
function, which could result
in a crash.
Trailer Wiring Harness
lf equipped, the trailer wiring
harness, with a 7-pin
connector is mounted on the
trailer hitch.

improperly or overloaded
trailer, unrestrained cargo,
improper trailer hitch
configuration, or improperly
inflated or incorrect vehicle
or trailer tires. See Towing
Equipment0356 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
blowouts. 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 blowouts.
Never load the trailer with
more weight than the tires are
designed to support. The load
rating is 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).
