injury or even fatal injury.
Make sure that no parts of the body are in the closing area.
If somebody becomes trapped:
R release the switch immediately, or
R press the switch in any direction during the automatic closing process
The closing process is stopped.

Correct driver's seat positionSeats, steering wheel and mirrors

The seats should only be occupied by
passengers, if possible.
R when the seat heating is in operation, do
not cover the seats with insulating mate-
rials, e.g. blankets, coats, bags, seat cov- ers, child seats or booster seats.
! Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam- aged.
i The head restraints in the front seats are
installed with the NECK-PRO system
(Y page 61). For this reason, it is not pos-
sible to remove the head restraints from
the front seats.
For more information, contact a qualified
specialist workshop. Adjusting the seats

steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. G

adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
Do not rotate the head restraints of the front
and rear seats. Otherwise, you cannot adjust
the height and angle of the head restraints to
the correct position.
Using the fore-and-aft adjustment, adjust the head restraint so that it is as close as possibleto your head.

Important safety notes G
WARNING
When the EASY-ENTRY/EXIT feature adjusts
the steering wheel, you and other vehicle
occupants – particularly children – could
become trapped. There is a risk of injury.
While the EASY-ENTRY/EXIT feature is mak-
ing adjustments, make sure that no one has
any body parts in the sweep of the steering
wheel.
Move the steering wheel adjustment lever if
there is a risk of entrapment by the steering
wheel. The adjustment process is stopped.
Vehicles with a memory function: if there is a
risk of becoming trapped by the steering
wheel, you can also one of the memory func- tion position buttons. The adjustment proc-
ess is stopped. G
WARNING
If children activate the EASY-ENTRY/EXIT fea- ture, they can become trapped, particularly
when unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. G
WARNING
If you drive off while the EASY-ENTRY/EXIT
feature is making adjustments, you could lose
control of the vehicle. There is a risk of an
accident. Always wait until the adjustment process is
complete before driving off.
The EASY-ENTRY/EXIT feature makes getting in and out of your vehicle easier.
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board com-
puter (Y page 240).
Position of the steering wheel when the
EASY-ENTRY/EXIT feature is active The steering wheel swings upwards when
you:
R remove the SmartKey from the ignition lock
R with KEYLESS-GO: open the driver's door;
KEYLESS-GO must be in position 1
R with the SmartKey: open the driver's
door; the SmartKey is in position 0or 1
must be in the ignition lock (Y page 149).
i The steering wheel only moves upwards if
it has not already reached the upper stop.
Position of the steering wheel for driv-
ing The steering wheel is moved to the last selec-
ted position when:
R the driver's door is closed
R with KEYLESS-GO: you press the Start/
Stop button once
or
R with the SmartKey: you insert the Smart-
Key into the ignition lock Steering wheel
115Seats, steering wheel and mirrors Z

When you close the driver's door with the
ignition switched on, the steering wheel is
also automatically moved to the previously
set position.
The last position of the steering wheel is
stored when you switch off the ignition or
when you store the setting with the memory
function (Y page 119).
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 posi-
tion 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 fea-
ture is activated in the on-board computer
(Y page 240). Mirrors
Exterior mirrors

WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. G
WARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g. when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder. X
Turn the SmartKey to position 1or 2in the
ignition lock (Y page 149).
X Press button :for the left-hand exterior
mirror or button ;for the right-hand exte-
rior mirror.
The indicator lamp in the corresponding
button lights up in red.
The indicator lamp goes out again after
some time. You can adjust the selected
mirror using adjustment button =as long
as the indicator lamp is lit.
X Press adjustment button =up, down, or to
the left or right until you have adjusted the
exterior mirror to the correct position. You
should have a good overview of traffic con- ditions.
The convex exterior mirrors provide a larger
field of vision.
After the engine has been started, the exte-
rior mirrors are automatically heated if the
rear window defroster is switched on and the
outside temperature is low. Heating takes a
maximum of ten minutes.
i You can also heat up the exterior mirrors
manually by switching on the rear window
defroster. 116
