driver's seat moves backwards when you:
R remove the SmartKey from the ignition lock
R open the driver's door when the SmartKey
is in the ignition lock or KEYLESS-GO is in
position 1
i The steering wheel only moves upwards if
it has not already reached the upper end
stop. The driver's seat only moves
backwards if it is not already in the
rearmost position.
Position of the steering wheel and the
driver's seat for driving
If you insert the SmartKey into the ignition
lock with the driver's door closed, depending
on the setting, the position of the steering
wheel and the driver's seat will be changed to
the previously set position.
The last position of the steering wheel or seat
is stored when:
R the ignition is switched off or
R the setting is stored with the memory
function.
Crash-responsive EASY-EXIT feature
If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering column
will move upwards when the driver's door is
opened. This occurs irrespective of the
position of the SmartKey in the ignition lock.
This makes it easier to exit the vehicle and
rescue the occupants.
The crash-responsive EASY-EXIT feature is
only operational if the EASY-EXIT/ENTRY
feature is activated in the on-board computer.

dehumidification on/off
Cooling is operational when the engine is
running and cools according to the selected
interior temperature for the vehicle. Cooling
also dehumidifies the air inside the vehicle
and, thereby, prevents the windows from
misting up.
GRisk of accident
If you switch off cooling with
dehumidification, the vehicle will not be
cooled and the air not dehumidified in warm
weather conditions. The windows can mist up
faster. This could result in your no longer
being able to observe the traffic conditions
properly and you may cause an accident.
iCondensation may collect on the
underside of the vehicle when the cooler is
operating.
