9-18 Driving and Operating
Steps for Determining Correct
Load Limit
Locate the statement The
1.
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs on your vehicle's
placard.
Determine the combined
2.
weight of the driver and
passengers that will be riding
in your vehicle.
Subtract the combined
3.
weight of the driver and
passengers from XXX kg or
XXX lbs.
The resulting figure equals
4.
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).
Determine the combined
5.
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.
If your vehicle will be towing
6.
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. See Trailer
Towing on page 9 70 for
important information on
towing a trailer, towing safety
rules and trailering tips.
