Adjusting

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 page48 and the infor-
mation on the active front head restraints
on
page47.
Adjusting seat
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page43.<

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.
>Increase or decrease curvature: press front
or rear section of switch.
>Shift curvature up or down: press upper or
lowers section of switch.
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.

LED in the button lights up.
To deactivate: Press button longer.
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.

Adjusting
46 The adjustment of the lumbar support is not

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.<
Comfort mode
1.Open the driver's door after unlocking or
switch on radio readiness.
2.Briefly press the desired memory button1
or2.
The system cancels the adjustment procedure
when you briefly press one of the seat adjust-
ment switches or one of the memory buttons.

tion on or off.
2.Press the desired memory button1 or2
and keep it pressed until the adjustment
process has been completed.

press the button again; the LED goes out.
Requesting with remote control
The last positions of the driver's seat, the exte-
rior rearview mirrors, and steering wheel are
stored for the remote control currently in use.
You can choose when the position is requested:
>Request when unlocking vehicle
>Request when opening driver's doorWhen using this feature, always make
sure that the footwell behind the driver's
seat is empty and unobstructed. Failure to do
so could cause injury to persons or damage to
objects behind the seat as a result of a rearward
movement of the seat.<
The system cancels the adjustment procedure
when you briefly press one of the seat adjust-
ment switches or one of the memory buttons.
Selecting automatic call-up
iDrive, for operating principle refer to page16.
1."Settings"
2."Door locks"
3."Last seat position auto."
The function for automatically calling up
the last seat position is switched on and is
stored for the remote control currently in use.
Switching off automatic call-up
Deactivate "Last seat position auto.".
Head restraints
A correctly adjusted head restraint reduces the
risk of spinal injury in the event of an accident.
Adjust the head restraint so that its center
is approximately at ear level. Otherwise
there is increased danger of injury in the event
of an accident. Only remove the head restraints
if no one will be sitting on the seat in question.
Reinstall the head restraints before transport-
ing passengers, as otherwise the head restraint
cannot provide its protective function.<
