the load within the vehicle. For this reason,
you should observe the following notes when
transporting a load:
R

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.

possible and as low down in the trunk as
possible.

upper edge of the seat backrests.
R Always place the load against the rear or
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 strong and
wear-resistant tie-downs. pad sharp edges

surfaces
R if the engine is often left idling for long
periods
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must
be checked more often. Further information
