Note before adjusting
Never attempt to adjust your seat while 
operating the vehicle. The seat could 
respond with unexpected movement and the 
ensuing loss of vehicle control could lead to an 
accident.
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.<
Also follow the instructions regarding damage 
to the safety belt on page52.
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; otherwise, the wind deflector 
will be damaged.<

 To ensure that the safety systems con-
tinue to provide optimized protection,

sure that the footwell behind the driver'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.<
Front head restraints
A correctly adjusted head restraint reduces the 
risk of injury to cervical vertebrae in an accident.
Adjust the head restraint so that its center 
is approx. at ear level. Otherwise there is 
increased danger of injury in the event of an 
accident.<
