CAUTION
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Stow cargo and luggage in the lugga ge compartment whenever possible.
●Do not place cargo or luggage in or on the following locations as the item may
get under the brake or accelerator pedal and prevent the pedals from being
depressed properly, block the driver’s vision, or hit the driver or passenger, caus-
ing an accident:
• At the feet of the driver
• On the passenger seat (when stacking items)
• On the package tray
• On the instrument panel
•On the dashboard
●Secure all items in the occupant compartment, as they may shift and injure some-
one during sudden braking, sudden swerving or an accident.
●Never allow anyone to ride in the luggage compartment. It is not designed for
passengers. The passenger should ride in th e seat with the seat belt properly fas-
tened. Otherwise, the passenger is much more likely to suffer death or serious
bodily injury, in the event of sudden br aking, sudden swerving or an accident.
■Capacity and distribution
●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.
