185 Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
1) The Tire and Loading Information placard
can be found on the driver’s door Bpillar.
This placard tells you important informa
tion about the number of people that can
be in the vehicle and the total weight that
can be carried in the vehicle. It also con
tains information on the proper size and
recommended tire inflation pressures for
the original equipment tires on your vehi
cle.2) The certification label, also found on the
driver’s door Bpillar, tells you about the
gross weight capacity of your vehicle,
called the Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight of
the vehicle, all occupants, fuel and cargo.
The certification label also tells you about
the front and rear axle weight capacity,
called the Gross Axle Weight Rating
(GAWR). The GAWR is the total allowable
weight that can be carried by a single axle
(front or rear). Never exceed the GVWR or
GAWR for either the front axle or rear
axle.

>Locate the statement "The combined weight
of occupants and cargo should never
exceed XXX kg or XXX lbs." on the Tire and
Loading Information placard.
The combined weight of all occupants and
cargo / luggage should never exceed the
weight referenced in that statement.
Seating capacity
The seating capacity gives you important
information on the number of occupants that
can be in the vehicle. The Tire and Loading
Information placard showing the seating
capacity is located on the driver’s door
Bpillar (

.
G
Warning!
Do not overload the tires by exceeding
the specified load limit as indicated on
the Tire and Loading Information placard
on the driver’s door Bpillar. Overload
ing the tires can overheat them, possibly
causing a blowout. Overloading the tires
can also result in handling or steering
problems, or brake failure.

Seating capacity information on the Tire
and Loading Information placardSteps for determining correct load limit
The following steps have been developed as
required of all manufacturers under Title 49,
Code of U.S. Federal Regulations, Part 575
pursuant to the "National Traffic and Motor
Vehicle Safety Act of 1966".
Step 1
>Locate the statement "The combined weight
of occupants and cargo should never ex
ceed XXX kg or XXX lbs." on your vehicle’s
Tire and Loading Information placard.
Step 2
>Determine the combined weight of the
driver and passenger that will be riding in
your vehicle.
Step 3
>Subtract the combined weight of the driver
and passenger from XXX kilograms or
XXX lbs.Step 4
>The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the "XXX" amount equals
540 lbs and there will be one 150 lbs
passenger in your vehicle, the amount of
available cargo and luggage load capacity
is 390 lbs (540 lbs 150 lbs = 390 lbs).
Step 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.
i
The maximum cargo compartment load is
100 lbs (50 kg).

>> Operation The following table shows examples on how to calculate total and cargo load capacities with varying seating configurations and number and size
of occupants. The following examples use a load limit of 540 lbs. This is for illustration purposes only. Make sure you are using the actual load
limit for your vehicle stated on the vehicle’s Tire and Loading Information placard (
page 186).
The higher the weight of all occupants, the less cargo and luggage load capacity is available.

Certification label
Even after careful determination of the
combined weight of all occupants and cargo as
to not exceed the permissible load limit, you
must make sure that your vehicle never
exceeds the Gross Vehicle Weight Rating
(GVWR) and the Gross Axle Weight Rating
(GAWR) for either the front or rear axle. You
can obtain the GVWR and GAWR from the
certification label. The certification label can
be found on the driver’s door Bpillar, see
"Technical data" (
page 293).
Gross Vehicle Weight Rating (GVWR) means:
the total weight of the vehicle, all occupants,
and all cargo must never exceed the GVWR.
Gross Axle Weight Rating (GAWR) means:
the total allowable weight that can be carried
by a single axle (front or rear).To assure that your vehicle does not exceed
the maximum permissible weight limits (GVWR
and GAWR for front and rear axle), have the
loaded vehicle (including driver, passenger,
and all cargo) weighed on a suitable commer
cial scale.
Recommended tire inflation
pressure
Your vehicle is equipped with the Tire and
Loading Information placard located on the
driver’s door Bpillar (
page 185).
The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. The tires can be considered cold if the
vehicle has been parked for at least 3 hours
or driven less than 1 mile (1.6 km).
G
Warning!
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated
tires wear excessively and/or unevenly,
adversely affect handling and fuel econ
omy, and are more likely to fail from being
overheated.
Do not overinflate tires. Overinflated
tires can adversely affect handling and
ride comfort, wear unevenly, increase
stopping distance, and result in sudden
deflation (blowout) because they are
more likely to become punctured or
damaged by road debris, potholes etc.
Do not overload the tires by exceeding
the specified load limit as indicated on
the Tire and Loading Information placard
on the driver’s door Bpillar. Overload
ing the tires can overheat them, possibly
causing a blowout. Overloading the tires
can also result in handling or steering
problems, or brake failure.

sures listed on Tire and Loading Information
placard on the driver’s door Bpillar.
Keeping the tires properly inflated provides
the best handling, tread life and riding com
fort.

Tire and Loading Information placard
with recommended cold tire inflation
pressures
The Tire and Loading Information placard
lists the recommended cold tire inflation
pressures for maximum loaded vehicle weight.
The tire inflation pressures listed apply to the
tires installed as original equipment.Important notes on tire inflation pressure
Tire temperature and tire inflation pressure
are also increased while driving, depending
on the driving speed and the tire load.
Tire inflation pressure changes by approxi
mately 1.5 psi (0.1 bar) per 18°F (10°C) of air
temperature change. Keep this in mind when
checking tire inflation pressure where the
temperature is different from the outside
temperature.
G
Warning!
If the tire inflation pressure drops
repeatedly:
• Check the tires for punctures from
foreign objects.
• Check to see whether air is leaking
from the valves or from around the rim.
