When driving
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Co nsult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. ( P. 1 7 3)
Example on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined wei ght of 366 lb
. (166 kg) are riding
in your vehicle, which has a total load capacity of 815 lb. (370 kg), the
available amount of cargo and luggag e load capacity will be as follows:
815 lb. — 366 lb. = 449 lb. (370 kg —166 kg = 204 kg)
In this condition, if 3 mo re passengers with the combined weight of 388 lb.
(176 kg) get on, the available cargo and luggage load will be reduced as fol -
lows:
449 lb. — 388 lb. = 61 lb. (204 kg — 176 kg = 28 kg)
As shown in the above example, if the number of occupants incr
eases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other w
ords, if an increase in the
number of occupants causes an excess of the total load capacity (com -
bined weight of occupants plus car go and luggage load), y
ou must
reduce the cargo and luggage on your vehicle.
