The Tire and Loading Information label also lists the tire
size of the original equipment tires (C) and the
recommended cold tire inflation pressures (D). For more
information on tires and inflation, see Tires on
page 5-52 and Inflation - Tire Pressure on page 5-58.
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 kg or XXX pounds" 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 kilograms or XXX pounds.
4-30
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, the 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
for your vehicle.
If your vehicle can tow a trailer, see Towing a Trailer on
page 4-35 for important information on towing a
trailer, towing safety rules, and trailering tips.
