Seats 
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. 
Also on the passenger's side, do not incline 
the backrest too far to the rear while the 
vehicle is being driven, as otherwise there 
is a danger in the event of an accident of 
'sliding under' the safety belt, eliminating 
the protection normally provided by the 
belt.< 
Please observe the information on damage 
to safety belts provided on page51 and the 
information on the active head restraints on 
page49.

ious functions after first selecting them with

tion, please observe the adjustment

This automatic system is influenced on 
both seats by each door as well as on the

Lumbar support adjustment 
5Lumbar support 
You can also adjust the contours of the 
backrest to obtain additional support in the 
lumbar region.

supplementary support to help you main-
tain a relaxed, upright sitting position. 
>Press front or rear: 
Increase or decrease curvature 
>Press top or bottom: 
Extend curvature upward or downward. 
Shoulder support adjustment 
6Adjust the tilt angle of the shoulder 
support:  
You can use the adjustable upper backrest 
for supplementary support in the shoulder 
region. This provides a relaxed driving 
position and helps relieve stress on the 
shoulder muscles. 
Make corrections in the forward/
backward adjustment of the seat to 
ensure that the safety belt still fits firmly 
against your body. If you do not do this, the 
protection provided by the safety belt may 
be reduced.<

ious functions after first selecting them with
