Steps for Determining the Correct Load Limit:
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 × 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 of your vehicle.
