Cargo and luggage
Capacity and distributionCargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capa city) — (Total weight of occupants)
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.
Take notice of the following informat ion about storage precautions, cargo
capacity and load.
● Stow cargo and luggage in the trunk whenever possible. Be sure all
items are secured in place.
● Be careful to keep the vehicle leve l. Placing the weight as far for-
ward as possible helps maintain vehicle balance.
● For better fuel economy, do not carry unnecessary weight.

●Aerosol cans
■Storage precautions
●Do not place anything on the package tray behind the rear seatback. 
Such items may be thrown about and possib ly injure people in the vehicle during
sudden braking or in an accident.
●Do not drive with objects on top of the instrument panel. 
They may interfere with the driver’s field of view or move during sharp accelera-
tion or turning, thus impairing the driver ’s control of the vehicle. In an accident
they may injure the vehicle occupants.
●Secure all items in the occupant compartment, as they may shift and injure some-
one during an accident or sudden braking.
■Weight of the load
●Improper loading may cause deterioration of steering or braking control result-
ing in an accident which may cause death or serious injury.
●Do not exceed the maximum axle weight ra ting or the total vehicle weight rating.
●Even if the total load of occupant’s weight and the cargo load is less than the total
load capacity, do not apply the load unevenly. Improper loading may cause dete-
rioration of steering or braking control which may cause death or serious injury.
