Note before adjusting
Never attempt to adjust your seat
while operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle con-
trol could lead to an accident.
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.

damage to the safety belt on page

Convertible: with the wind deflector
fitted, do not incline the front seat
backrests too far backwards if the seat is to
be moved back to the end position, as oth-
erwise the wind deflector will be dam-
aged.
