gross vehicle weight or the gross axle
weight rating of the vehicle (including
occupants). The values are specified on the
vehicle identification plate on the B-pillar of
the driver's door.
R The trunk is the preferred place to carry
objects.
R Position heavy loads as far forwards as
possible and as low down in the trunk as
possible.
R The load must not protrude above the
upper edge of the seat backrests.

front seat backrests. Make sure that the
seat backrests are securely locked into
place.
R Always place the load behind unoccupied
seats if possible.
R Use the cargo tie down rings and the parcel
nets to transport loads and luggage.
R Use cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load.
R Secure the load with sufficiently stronga nd
wear-resistant tie-downs. pad sharp edges
for protection. Stowage space
