Tire and Loading Information Label
A vehicle specic Tire and Loading Information
label is attached to the vehicle’s center pillar
(B-pillar). With the driver’s door open, you will nd
the label attached below the door lock post (striker).
The tire and loading information label lists the
number of occupant seating positions (A), and the
maximum vehicle capacity weight (B) in kilograms
and pounds. The vehicle capacity weight includes
the weight of all occupants, cargo, and all
nonfactory-installed options.The Tire and Loading Information label also lists the
tire size of the original equipment tires (C) and the
recommended cold tire ination pressures (D). For
more information on tires and ination, seeTires on
page 386andInation - Tire Pressure on page 393.
There is also important loading information on the
Certication/Tire label. It tells you the Gross
Vehicle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for the front and rear
axles. See “Certication/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.

Certication Label
A vehicle specic Certication/Tire label is found
on the rear edge of the driver’s door.
The label shows the size of your original tires and
the ination pressures needed to obtain the gross
weight capacity of your vehicle. This is called the
Gross Vehicle Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all occupants,
fuel, and cargo.
The Certication/Tire label also tells you the
maximum weights for the front and rear axles,
called the Gross Axle Weight Rating (GAWR).To nd out the actual loads on your front and rear
axles, you need to go to a weigh station and weigh
your vehicle. Your dealer can help you with this. Be
sure to spread out your load equally on both sides
of the centerline.
Never exceed the GVWR for your vehicle or the
GAWR for either the front or rear axle.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.

Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inated to the
upper limit for cold tires. You will nd these
numbers on the Certication/Tire Label at the rear
edge of the driver’s door, or seeLoading Your
Vehicle on page 321. Then be sure you do not go
over the GVW limit for your vehicle, including
the weight of the trailer tongue.
Hitches
It is important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough
roads are a few reasons why you will need the
right hitch. Here are some rules to follow:
If you will be pulling a trailer that, when
loaded, will weigh more than 2,000 lbs
(900 kg), be sure to use a properly mounted,
weight-carrying hitch and sway control of
the proper size. This equipment is very
important for proper vehicle loading and good
handling when you’re driving.
Will you have to make any holes in the body of
your vehicle when you install a trailer hitch?If you do, remember to seal the holes when you
remove the hitch. If you do not seal them,
deadly carbon monoxide (CO) from your
exhaust can get into your vehicle. SeeEngine
Exhaust on page 127. Dirt and water can, too.
Safety Chains
You should always attach chains between your
vehicle and your trailer. 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. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for
attaching safety chains and do not attach them to
the bumper. Always leave just enough slack so
you can turn with your rig. Never allow safety
chains to drag on the ground.
Trailer Brakes
If your trailer weighs more than 1,000 lbs (450 kg)
loaded, then it needs its own brakes – and they
must be adequate. Be sure to read and follow the
instructions for the trailer brakes so you will be
able to install, adjust and maintain them properly.
