Adjusting comfort seat*
In this seat, you can also adjust:
1Backrest width
2Shoulder support
3Thigh support
4Lumbar support, see below.
Shoulder support: the adjustable upper back-
rest also supports the back in the shoulder
region. This provides a relaxed driving position
and helps relieve stress on the shoulder mus-
cles.
After making corrections in the forward/
backward adjustment of the seat, make
sure that the safety belt still fits snugly against
your body. Failure to do so may reduce the pro-
tection provided by the safety belt.<
Adjusting sport seat*
In this seat, you can also adjust the thigh sup-
port 3, see above.
Adjusting lumbar support*
You can also adjust the contour of the backrest
to obtain additional support in the lumbar
region.

Adjustments
40 The upper hips and spinal column receive sup-
plementary support to help you maintain a
relaxed, upright sitting position.
>Increase or decrease curvature: push
switch forward or back.
>Shift curvature up or down: push switch up
or down.
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 tempo-
rarily opens all the way.

tions for the driver's seat and passenger seat
*,
external rearview mirrors, and steering wheel.
