2-5. Driving information
(6) If your vehicle will be towing a trailer, 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.
Example on your vehicle
When 2 people with the combined weight of 366 lb. (166 kg) are
riding in your vehicle, which has a total load capacity of 1190 lb. (540
kg), the available amount of cargo and luggage load capacity will be
as follows:
1190 lb. − 366 lb. = 824 lb. (540 kg − 166 kg = 374 kg)
In this condition, if 3 more passengers with the combined weight of
388 lb. (176 kg) get on, the available cargo and luggage load will be
reduced as follows:
824 lb. − 388 lb. = 436 lb. (374 kg − 176 kg = 198 kg)
As shown in the above example, if the number of occupants
increases, the cargo and luggage load will be reduced by an amount
that equals the increased weight due to the additional occupants. In
other words, if an increase in the number of occupants causes an
excess of the total load capacity (combined weight of occupants plus
cargo and luggage load), you must reduce the cargo and luggage on
your vehicle.
