Steps 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 (Vehicles equipped with placard 
Example A)
Locate the statement “The combined 
weight of occupants and cargo should 
never exceed XXX kg or XXX lbs.” on 
your vehicle’s placard.
Step 1 (Vehicles equipped with placard 
Example B)
Locate the heading “Vehicle Capacity 
Weight” on your vehicle’s placard.
Step 2
Determine the combined weight of the 
driver and passengers that will be 
riding in your vehicle.Step 3
Subtract the combined weight of the 
driver and passengers from XXX kilo-
grams or XXX lbs.
Step 4
The resulting figure equals the avail-
able amount of cargo and luggage load 
capacity. For example, if the “XXX” 
amount equals 1400 lbs and there will 
be five 150 lbs passengers in your 
vehicle, the amount of available cargo 
and luggage load capacity is 650 lbs. 
(1400-750 (5 x150) = 650 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.Step 6 (if applicable)
If your vehicle will be towing a trailer, 
load from your trailer will be trans-
ferred to your vehicle. Consult this 
manual to determine how this reduces 
the available cargo and luggage load 
capacity of your vehicle (
page 321).
The following table shows examples on 
how to calculate total and cargo load 
capacities with varying seating configura-
tions and number and size of occupants. 
The following examples use a load limit 
of 1500 lbs. This is for illustration 
purposes only. Make sure you are using 
the actual load limit for your vehicle stated 
on the vehicle’s placard (
page 317).
