according to the vehicle load
(Y page 278).
X Driving style: adapt your driving style
according to the vehicle load. Load distribution
General notes
! Excessive loads on individualp oints of the
cargo floor or on the load surface impair
vehicle handling characteristics and could
cause damage to the floor covering.
The overall center of gravity of the load should
always be as low as possible, centered and
between the axles near the rear axle.
On Cargo Vans/Passenger Vans:
X Always transport loads in the cargo
compartment.
X Always place the load against the backrests
of the rear bench seat.
X Move large and heavy loads as far towards
the front of the vehicle as possible against the rear bench seat. Stow the load flush
with the rear bench seat.
X Always additionally secure the load with
suitable load-securing aids or tie downs.
Observe the following notes:
R Do not stack loads higher than the upper
edge of the backrests.
R Transport loads behind seats that are not
occupied.
R If the rear bench seat is not occupied, insert
the seat belts crosswise into the buckle of
the opposite seat belt. Securing loads
Important safety notes
G
WARNING
If you attach the tie-down incorrectly when
securing the load, the following may occur in
the event of abrupt changes in direction,
braking maneuvers or an accident:
R the cargo tie-down rings may become
detached or the tie-down may tear if the
permissible load is exceeded
R the load may not be restrained.
This may cause the load to slip, tip over or be
tossed about, striking vehicle occupants.
There is a risk of an accident and injury.
Always tension the tie-downs in the proper
manner and only between the described
cargo tie-down rings. Always use tie-downs
designed specifically for the loads. G
WARNING
You may not transport anyone in the cargo
compartment or on the load surface. Never
let more people ride in the vehicle than there
are seat belts available. Make sure everyone
riding in the vehicle is correctly restrained
with a separate seat belt. Never use a seat
belt for more than one person at a time. 234
