Observe the following points:
R
Adjust the seat backrest until your arms are
slightly angled when holding the steering
wheel.
R Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
R Adjust the head restraint so that it is as
close to the head as possible. The center of
the head restraint must support the back of
the head at eye level.
R Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury. G
Warning!
The power seats can be operated at any time.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury. G
Warning!
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see “Children in the vehicle”.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/ or the child is not properly secured in the child
restraint.
G
Warning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so 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.
Do not drive the vehicle without the seat head
restraints. Head restraints are intended to
help reduce injuries during an accident. Seat adjustment
! When moving the seats, make sure there
are no items in the footwell or behind the
seats. Otherwise, you could damage the
seats and/or the items.

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.

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

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!

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.
