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.<
Please observe the information on damage 
to safety belts provided on page 41 and the 
information on the active head restraints on 
page 40.

tions, several other adjustment options are 
available with the comfort seat: 
1Backrest width 
By adjusting the backrest width, you 
can increase or reduce lateral support 
2Shoulder support 
You can use the adjustable upper back-
rest 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.<

support is provided for the thigh 
4Lumbar support, see below 
Sports seat* adjustment 
In addition to the seat cushion, on the 
sports seat you can adjust the thigh sup-
port 3, see above. 
Easy entry/exit* 
The backrest width automatically moves as 
high up and far forward as possible to ease 
driver entry and exit before then returning 
to the standard or stored memory setting. 
This automatic feature is governed by the 
driver's door and the ignition lock.

are centered roughly at the level of your 
ears
