Important safety notes
G
Risk of injury
The electrically adjustable steering wheel can
still be adjusted when there is no key in the
ignition lock. Therefore, do not leave children
unsupervised in the vehicle, as they could
become trapped if the steering wheel is adjus-
ted. G
Risk of accident
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustmen tmechanism is
locked in position .You might otherwise drive
without the steering wheel adjustmen tmech-
anism being locked in position .As a result,
you could be distracted from road and traffic
conditions by an unintentional movement of
the steering wheel and thereby cause an acci-
dent. 90
Steering wheelSeats, steering wheel and mirrors
Problems with the steering wheel heat-
ing
If the steering wheel heating indicator lamp
on the lower left lever of the steering column
is flashing, the steering wheel heating has
switched off automatically. The vehicle's
electrical system voltage is too low because
too many electrical consumers are switched
on.
X
Switch off electrical consumers which you
do not need, such as the rear window heat-
ing or interior lighting.
Once the battery is sufficiently charged, the
steering wheel heating will switch back on
automatically. EASY-ENTRY/EXIT system
G
Risk of injury
Make sure that nobody can become trapped
when you activate the EASY-ENTRY/EXIT fea-
ture.
If there is a risk of someone becoming trap-
ped, stop the adjustment procedure. To halt
the procedure:
R move the switch for steering wheel adjust-
ment in the opposite direction to that in
which the steering wheel is moving.
R press one of the memory function position
buttons.
Never leave children unsupervised in the vehi-
cle. They could open the driver's door and
thereby unintentionally activate the EASY-
ENTRY/EXIT feature and become trapped.
The EASY-ENTRY/EXIT feature makes getting
in and out of your vehicle easier.
The steering wheel swings upwards when
you:
R remove the key from the ignition lock
R open the driver's door and KEYLESS-GO is
in position 1
R open the driver's door and the key is in
position 0or 1in the ignition lock i
The steering wheel only moves upwards if
it has not already reached the upper end
stop.
If you insert the key into the ignition lock with
the driver's door closed, the steering wheel is
automatically moved to the previously set
position.
The last position of the steering wheel is
stored after each manual setting or when you
store the setting with the memory function
(Y page 95).
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board com-
puter (Y page 211).
i If the crash-responsive EASY-EXIT feature
is triggered in an accident, the steering col-
umn will move upwards when the driver's
door is opened. This occurs irrespective of
the position of the key 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 after an accident if the
EASY-EXIT/ENTRY feature is activated in
the on-board computer. Mirrors

ror on the driver's side Memory functions
Storing settings
With the memory function, you can store up
to three different settings, e.g. for three dif-
ferent people.
The following settings are stored as a single
memory preset:
R position of the seat, backrest and head
restraint
R active multicontour seat :seat cushion
length, seat backrest side bolsters, contour
of the backrest, dynamic function level set-
ting R
driver's side: steering wheel position
R driver's side: position of the exterior mir-
rors on the driver's and front-passenger
sides G
Risk of injury
The memory function can still be used when
the key has been removed. For this reason,
children should never be left unsupervised in
the vehicle. They could otherwise become
trapped when adjusting the seat or the steer-
ing wheel. G
Risk of accident
Only use the memory function on the driver's
side when the vehicle is stationary. Other-
wise, you could be distracted from the traffic
conditions by the steering wheel and seat
moving of their own accord, and as a result
cause an accident. X
