Seats
Note before adjusting
Never attempt to adjust your seat while
the vehicle is moving. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an
accident.
Also on the passenger side, do not incline the
backrest too far to the rear while the vehicle is
being driven, otherwise there is a danger in the
event of an accident of sliding under the safety
belt, eliminating the protection normally pro-
vided by the belt.<
Please follow the instructions on damage to
safety belts provided on page46 and the infor-
mation on the active front head restraints
on
page44.
Adjusting seat
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page41.<

Shoulder support*
This also supports the back in the shoulder
area, This provides a relaxed driving position
and helps relieve stress on the shoulder mus-
cles.
Lumbar support*
You can also adjust the contour of the backrest
to obtain additional support in the lumbar
region.
The upper hips and spinal column receive sup-
plementary support to help you maintain a
relaxed, upright sitting position.

Adjusting active backrest width*
First set a comfortable backrest width, see
above. Based on the backrest width set, the lat-
eral support is automatically adapted to the cur-
rent driving situation.
The adaptation of the backrest width and the
speed of the adjustment vary depending on the
program. You can select from among three pro-
grams from comfort to sport. The "Sport" pro-
gram provides increased lateral support on both
sides when driving through a quick succession
of curves.
Press the button repeatedly until the desired
program is shown on the Control Display.
The LED in the button lights up.
To deactivate: press button longer.
You can also activate your preferred program
for the active backrest width adjustment of the
driver's seat with the button on the steering
wheel, refer to MDrive on page50.
Easy entry/exit*
To facilitate entry and exit, the backrest width
temporarily opens all the way.
Seat, mirror and steering
wheel memory
You can store and request two different posi-
tions for the driver's seat and passenger seat
*,
exterior rearview mirrors, and steering wheel.
The adjustment of the lumbar support is not
stored in the memory.

2.Set the desired seat, exterior mirror and
steering wheel positions.
3.Press the button:
The LED in the button lights up.
4.Press the desired memory button1 or2:

Requesting
Do not request a position from the mem-
ory while the vehicle is moving. There is a
risk of accident from unexpected movement of
the seat or steering wheel.<

switch on radio readiness.
