Example 2
A. Vehicle Capacity Weight
The Tire and Loading Information label shows the seating
capacity and the total weight your vehicle can properly
carry. This weight is called the vehicle capacity weight. If
your vehicle has the Tire and Loading Information label,
Example 1, the label is attached to the center pillar, near
the driver's door latch. If your vehicle has the
Tire-Loading Information label, Example 2, the label is on
the rear edge of the driver's door.
4-34
The Tire and Loading Information label also gives you the
size and recommended inflation pressure for the
factory-installed, original equipment tires on your vehicle.
For more information on tires and inflation see Tires on
page 5-49 and Inflation - Tire Pressure on page 5-56.
There is also important loading information on the
Certification label. It tells you the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle Weight Rating
(GAWR) for the front and rear axle; see "Certification
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
pounds" on your vehicle 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 kilograms or XXX pounds.
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.).
