On the front passenger side as well, do not
tilt the backrest too far toward the rear
while driving. Failure to observe this pre-
caution can prevent the belt from providing
effective protection against injury, as the
passenger could slide under the belt in an
accident.
Make sure that the footwell behind the
driver's and front passenger's seat is empty
and unobstructed. If you fail to do so, any
persons or objects behind the seat could
be injured or damaged by a rearward
movement of the seat.<
Please observe the information on damage
to safety belts provided on page 41 and the
information on the active head restraints on
page 40.

any safety guidelines posted at the
service station.<
Put the filler cap in the bracket attached to
the fuel filler door.
When refueling, insert the filler nozzle com-
pletely into the filler pipe. Lifting the filler
