Rear seat head restraints
G
Warning!
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints. G
Warning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that it
is as close to the head as possible and the
center of the head restraint supports the back
of the head at eye level. This will reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.
Do not drive the vehicle without the seat head
restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident. G
Warning!
Make sure the rear seat head restraints
engage when placing them upright manually.
Otherwise their protective function cannot be
ensured.
The back of the head will not be supported in
the event of a collision. That could cause
serious or even fatal injuries. Rear seat
occupants can be seriously injured or killed.
Folding rear seat head restraints back The rear seat head restraints can be folded
backward for increased visibility. X

Easy-entry/exit feature
This feature allows the driver an easier entry
into and exit from the vehicle. When entering
and exiting the vehicle, the steering wheel is
in its uppermost position.
The easy-entry/exit feature can be activated
or deactivated in the Convenience submenu
of the control system (Y page 124). G
Warning!
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To stop steering wheel movement, move
steering wheel adjustment stalk or press one
of the memory position buttons.
Do not leave children unattended in the
vehicle, or with access to an unlocked vehicle.
Children could open the driver’s door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
With the easy-entry/exit feature activated,
the steering wheel will return to its last set
position when you close the driver’s door with
the ignition switched on. The steering wheel
will also return to its last set position when
you insert the SmartKey into the starter
switch or press the KEYLESS-GO start/stop
button once with the driver’s door closed.
i The last set steering wheel position is
stored when the ignition is switched off or
the position is stored in memory
(Y page 86).
With the easy-entry/exit feature activated,
the steering wheel tilts upwards when you
remove the SmartKey from the starter switch.
The steering wheel also tilts upwards when
you open the driver’s door with the SmartKey in starter switch position
0 or 1 or the
KEYLESS-GO start/stop button in position 1.
i When the current position for the steering
wheel is in the uppermost tilt position, the
steering wheel will no longer be able to
move upward when the easy-entry/exit
feature is activated.
The adjustment procedure is briefly
interrupted when the engine is started. G
Warning!
Let the system complete the adjustment
procedure before setting the vehicle in
motion. All steering wheel adjustment must
be completed before setting the vehicle in
motion. Driving off with the steering wheel
still adjusting could cause the driver to lose
control of the vehicle.
Crash-responsive exit aid When you open the driver’s door after an
accident has occurred, the steering column
moves up. The position of the SmartKey in the
starter switch is insignificant. This function
facilitates exiting as well as rescue of vehicle
occupants.

triggered when the easy-entry/exit feature is
activated via the control system.
