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 observe the information on damage to
safety belts provided on page50 and the infor-
mation on the active front
head restraints* on
page49.
Seat adjustment
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page45.<

cles.

to obtain additional support in the lumbar
region.

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.
Press program button once:
>"Comfort" program: one LED
>"Normal" program: two LEDs
>"Sport" program: three LEDs
To switch off: 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
*,
external rearview mirrors, and steering wheel.
The adjustment of the lumbar support is not
stored in the memory.

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.
2.Briefly press the desired memory button1
