For safety reasons, the driver’s seat will
not return to its last set position if the
system recognizes the last set position as
an extreme forward position. Instead, the
driver’s seat will remain at or move to a
factory-set maximum forward position. To
again fully return the driver’s seat to your
last set position or to memory position,
adjust the seat to the desired position or
press and hold the respective memory
position button (Y page 274).
i The last set driver’s seat and steering
wheel positions are stored when the
ignition is switched off and the position is
stored in memory.
i If the current position for the steering
wheel is in the uppermost tilt position, the
steering wheel will not move.
If the current seat position is within a
factory-set position range and the system
recognizes the current seat position to be
rearward enough for easy entry and exit,
the driver’s seat will not move to the rear.
The adjustment procedure is interrupted
briefly when the engine is started. G
Warning!
Let the system complete the adjustment
procedure before setting the vehicle in
motion. All driver’s seat and steering wheel
adjustments must be completed before
setting the vehicle in motion. Driving off with
the driver’s seat/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. The crash-responsive exit aid can only be
triggered
when

the easy-entry/exit feature is
activated via the control system. 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.268

Make sure absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
