224 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.

228 DRIVING AND OPERATING
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 0248.
{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).
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
0367.
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.

Tire and Loading Information Label
Example Label
A vehicle-specific Tire and
Loading Information label is
attached to the center pillar
(B-pillar). The tire and loading
information label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading Information
label also shows the size of the
original equipment tires (3) and
the recommended cold tireinflation pressures (4). For more
information on tires and inflation
see
Tires 0337 and
Tire Pressure 0343.
There is also important loading
information on the vehicle
Certification/Tire label. It may
show the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle
Weight Rating (GAWR) for the
front and rear axle. See
“Certification/Tire Label” later in
this section.“Steps for Determining Correct Load
Limit–
1.
Locate the statement "The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs." on your
vehicle’s placard.
2.Determine the combined weight
of the driver and passengers
that will be riding in your
vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the "XXX" amount
equals 1400 lbs. and there will
be five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) = 650 lbs.)
5.Determine the combined weight
of luggage and cargo being
loaded on the vehicle. That
weight may not safely exceed
the available cargo and luggage
load capacity calculated in
Step 4.
6.If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your
vehicle. Consult this manual to

determine how this reduces the
available cargo and luggage
load capacity of your vehicle.”
See Trailer Towing 0293 for
important information on towing
a trailer, towing safety rules and
trailering tips.

weight of the driver, passengers,
and cargo should never exceed the
vehicle's capacity weight.
Certification/Tire Label
Label Example
A vehicle-specific Certification/
Tire label is attached to the center
pillar (B-pillar).
The label may show the size of the
vehicle's original tires and the
inflation pressures needed to
obtain the gross weight capacity
of the vehicle. The label shows the
gross weight capacity of the
vehicle. This is called the GrossVehicle Weight Rating (GVWR).
The GVWR includes the weight of
the vehicle, all occupants, fuel,
and cargo.
The Certification/Tire label may
also show the maximum weights
for the front and rear axles, called
the Gross Axle Weight Rating
(GAWR). To find out the actual
loads on the front and rear axles,
weigh the vehicle at a weigh
station. Your dealer can help with
this. Be sure to spread the load
equally on both sides of the
centerline.
CautionOverloading 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.
.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.

DRIVING AND OPERATING 293
.Shift into a gear.
.Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more often
when used to tow trailers. See
Maintenance Schedule 0380. It is
especially important to check the
transmission for fluid leaks, engine
oil, axle lubricant, belts, cooling
system, and brake system before and
during each trip.
Check periodically that all nuts and
bolts on the trailer hitch are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
0 320.
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
See “Weight-Distributing Hitch
Adjustment ”under Towing Equipment
0 297 to determine if equalizer bars
are required to obtain the maximum
trailer weight rating.
See “Trailer Brakes ”under Towing
Equipment 0297 to determine if
brakes are required based on your
trailer's weight.
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.

294 DRIVING AND OPERATING
{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 later in this section.To check that the weight of the
vehicle and trailer are within the
GCWR for the vehicle:
1. Start with the curb weight from the Trailering Information Label.
2. Add the weight of the trailer loaded with cargo and ready for the trip.
3. Add the weight of all passengers.
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 0228. When calculating
the GVWR with a trailer attached, the
trailer tongue weight must be
included as part of the weight the
vehicle is carrying.

Cadillac XT6 Owner Manual (GMNA-Localizing-U.S./Canada-14574701) -

DRIVING AND OPERATING 295
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.
