The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Please pay attention to and comply with
the following instructions when loading the
vehicle and transporting cargo:


Always place items being carried
against front or rear seat backrests,
and fasten them as securely as possi-
ble.


The heaviest portion of the cargo
should always be kept as low as possi-
ble against front or rear seat backrests.For additional safety when transporting
cargo while the rear seats are unoccupied,
fasten the outer seat belts crosswise into
the opposite side buckles.
i
The cargo compartment is the preferred
place to carry objects. The expanded cargo com-
partment (
page 284) should only be used for
items which do not fit in the cargo compartment
alone.
