qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.
! Do not forget that the weather can
change abruptly. Make certain that the
sliding sunroof is closed when you leave the
vehicle. The vehicle electronics can be
damaged if water enters the vehicle
interior.

Seats
Important safety notes
GWARNING
In order to avoid possible loss of vehicle
control, all seat, head restraint, steering
wheel and rear view mirror adjustments, as
well as fastening of seat belts, must be done
before setting the vehicle in motion.
GWARNING
Do not adjust the driver's seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never travel in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. This could cause serious or
fatal injuries. The seat backrest and seat belts
provide the best restraint when the wearer is
in a position that is as upright as possible and
seat belts are properly positioned on the
body.
GWARNING
Your seat belt must be adjusted so that you
can correctly fasten your seat belt.
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 and the center
of the head restraint supports 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.GWARNING
The electrically adjustable 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.
GWARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child. For additional information, see the
"Children in the vehicle" section.
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.
GWARNING
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.
Seats97Seats, steering wheel and mirrorsZ

Do not drive the vehicle without the seat head
restraints. Head restraints are intended to
help reduce injuries during an accident.
! To avoid damage to the seats and the seat
heating, observe the following information:
R keep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
R if the seat covers are damp or wet, do not
switch on the seat heating. The seat
heating should also not be used to dry
the seats.
R clean the seat covers as recommended;
see the "Interior care" section.
R do not transport heavy loads on the
seats. Do not place sharp objects on the
seat cushions, e.g. knives, nails or tools.
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
materials, e.g. blankets, coats, bags,
seat covers, child seats or booster seats.
! Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
i The head restraints cannot be removed.

Adjusting the front-passenger seat
from the driver’s seat
GWARNING
When adjusting the front passenger seat,
make sure the seat, if occupied, is as far from
the front passenger front air bag as possible.
Otherwise, the passenger could be seriously
or even fatally injured in the event of an
accident or braking maneuver.

Rear seat head restraints
GWARNING
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.
GWARNING
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.
GWARNING
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.
