WARNING
● The height of the driver seat must not be adjusted while driving. Fail-
ure to do so could result in an accident.
● Be careful when adjusting the seat height. Injuries can be caused if
the seat height is adjusted without due care and attention.
Adjusting the backrest angle
– Lean forwards to take your weight off the backrest.
– Turn the adjuster wheel 3
⇒ Fig. 104 to set the angle of the
backrest as required.
WARNING
The front backrests must not be reclined for driving. Otherwise, seat
belts and the airbag system might not protect as they should, with the
subsequent danger of injury.
Adjusting lumbar support*
– Do not exert any pressure on the backrest and turn adjuster
wheel 4 ⇒ Fig. 104 to adjust lumbar support.
As you make the adjustments, the curvature of the cushioned area of the
lumbar region becomes more or less acute. In this way, it adapts to the nat-
ural curvature of the spine.

Seats and storage compartments
– Press the rear part of the adjuster switch to decrease the con-
tour of the lumbar support.
Adjusting the height
– Press the top part of the adjuster switch to move the contour
upwards.
– Press the bottom part of the adjuster switch to move the con-
tour down.
The lumbar support provides effective support for the natural curvature of
the spine to give a more relaxed seating position, especially on long jour-
neys. Driver seat memory*
Description
The memory buttons in the driver door can be used to store
and recall up to four different positions for the driver seat
and exterior mirrors.

Memory system
Memory buttons
Using memory buttons 1, 2, 3 and 4 ⇒ Fig. 109, you can store and recall the
seat and exterior mirror positions for up to four different drivers.
STOP
button
The seat memory will be disabled if the STOP button is in the up position
(press and release). The word will light up next to the STOP button (only
visible when the lights are switched on).
The stored settings will all remain in the memory. However, the seat and the
exterior mirrors can now only be adjusted using the conventional electrical
adjustment. Use of the STOP
button is recommended to disable the memory

system when the vehicle is being driven temporarily by a different driver
whose settings do not need to be stored in the memory.
Note
You can also use the remote control to call up the stored settings
⇒ page 141.
Storing settings
The STOP button must be in its down position (pressed in) before
you can store the desired settings.
– Adjust the driver seat as required ⇒ page 137.
– Adjust both exterior mirrors ⇒ page 133.
– Press and hold the MEMO
button. At the same time, press one
of the memory buttons for at least a second.
– Release both buttons. The setting is now stored on the selected
memory button.
Any new setting selected automatically cancels the existing setting stored
on the memory button. It is best to begin with memory button No. 1 for the
first driver and then assign the other memory buttons to each subsequent
driver.
The seat and mirror positions are stored when the vehicle is locked with the
remote control and are assigned to the remote control key. The exterior mir-
rors adjust automatically to the previous position when you unlock the vehi-
cle; the driver seat adjusts automatically when you open the driver door.
However, this does not delete the settings stored in memory buttons 1 to 4.
These settings can be enabled at any time. Activating settings
Stored settings can be recalled using either the memory but-
tons or the remote control (remote control key).
Using the memory buttons
– If the driver door is open, press the desired memory button
briefly.
– If the driver door is closed, press and hold down the appropri-
ate memory button until the seat and exterior mirrors reach
their programmed positions.
Using the remote control
– Unlock the vehicle using the remote control and open the driver
door within the next ten minutes.
The seat adjustment will have to be called up using the memory buttons if
the driver door is not opened within 10 minutes after unlocking the vehicle
with the remote control.
WARNING
● For safety reasons, the seat must only be adjusted when the vehicle
is at a standstill. Failure to do so could result in an accident.
● In an emergency, the memory function can be stopped at any time by
pressing the STOP button or by briefly pressing any of the memory but-
tons.
