On the front passenger side as well, do not tilt
the backrest too far toward the rear. Failure to
observe this precaution 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 unob-
structed. 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.<
Also observe the instructions regarding dam-
age to the safety belt on page49.
Convertible: with the wind deflector fitted,
do not incline the front seat backrests too
far backward if the seat is to be moved back to
the end position, as otherwise the wind deflec-
tor will be damaged.<
