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, seeTowing the
Vehicle 0318.
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 tire inflation
pressures (4). For more information on
tires and inflation see Tires0287 and
Tire Pressure 0293.
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 0251 for important
information on towing a trailer, towing
safety rules and trailering tips.
Example 1
1.Vehicle Capacity Weight for
Example 1 = 453 kg (1,000 lbs).
2.Subtract Occupant Weight @
68 kg (150 lbs) × 2 = 136 kg
(300 lbs).
3.Available Occupant and Cargo
Weight = 317 kg (700 lbs).
Example 2
1.Vehicle Capacity Weight for
Example 2 = 453 kg (1,000 lbs).
2.Subtract Occupant Weight @
68 kg (150 lbs) × 5 = 340 kg
(750 lbs).
3.Available Cargo Weight = 113 kg
(250 lbs).

Caution (Continued)
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 See
“Trailer Brakes” underTowing
Equipment 0254 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.
{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.
Gross Vehicle Weight Rating (GVWR)
For information about the vehicle's
maximum load capacity, see
Vehicle Load
Limits 0196. 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.

320 Vehicle Care
Install the tow eye into the socket and turn
it until it is fully tightened.
When the tow eye is removed, reinstall the
cover with the notch in the original position.
To tow the vehicle behind another vehicle
for recreational purposes, such as behind a
motor home, seeRecreational Vehicle
Towing 0320.
Recreational Vehicle Towing
Recreational vehicle towing means towing
the vehicle behind another vehicle –such as
behind a motor home. The two most
common types of recreational vehicle
towing are known as dinghy towing and
dolly towing. Dinghy towing is towing the
vehicle with all four wheels on the ground.
Dolly towing is towing the vehicle with two
wheels on the ground and two wheels up
on a device known as a dolly.
Here are some important things to consider
before recreational vehicle towing:
.Before towing the vehicle, become
familiar with the local laws that apply to
recreational vehicle towing. These laws
may vary by region.
.The towing capacity of the towing
vehicle. Be sure to read the tow vehicle
manufacturer's recommendations.
.How far the vehicle will be towed. Some
vehicles have restrictions on how far and
how long they can tow.
.The proper towing equipment. See your
dealer or trailering professional for
additional advice and equipment
recommendations.
.If the vehicle is ready to be towed. Just
as preparing the vehicle for a long trip,
make sure the vehicle is prepared to be
towed.
Dinghy Towing
Caution
If the vehicle is towed with all four
wheels on the ground, the drivetrain
components could be damaged. The
repairs would not be covered by the
vehicle warranty. Do not tow the vehicle
with all four wheels on the ground.
The vehicle was not designed to be towed
with all four wheels on the ground. The
vehicle may be towed using a platform
trailer with all four wheels off the ground.
Some vehicles may be dolly towed. See the
following information on dolly towing.
Dolly Towing (All-Wheel-Drive Vehicles)
All-wheel-drive vehicles cannot be towed
with two wheels on the ground. To properly
tow these vehicles, they should be placed on
a platform trailer with all four wheels off of
the ground.
