Loading and storing
Loading instructions
GWarning!
Always fasten items being carried as securely
as possible using cargo tie-down hooks and
fastening materials appropriate for the weight
and size of the load.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
The trunk is the preferred place to carry
objects. Always use cargo tie-down hooks
when transporting cargo. Do not place
anything on the rear-window shelf.
Never drive a vehicle with the trunk open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
Load distribution
The total load weight including vehicle
occupants and luggage/cargo should not
exceed the total load limit indicated on the
