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.

Comfort seat* adjustment
In addition to the electric power seat func-
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.<
3Thigh support
Adjust the thigh support until the ideal
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.

safety, we request that you read and com-
ply with the following:

are centered roughly at the level of your
ears
>Do not install seat or head-restraint
covers
>Never use the head restraints as sup-
ports for suspending objects of any
kind, such as clothes hangers. Refrain
from mounting accessories on either
the seat or the head restraint.<
Rear seats: adjusting the height
>Upwards: by pulling
>Downwards: press the button, arrow 1,
