Important safety notes
G
WARNING
The seats can still be adjusted when there is
no key in the ignition lock. For this reason,
children should never be left unsupervised in
the vehicle. They could otherwise become
trapped when adjusting the seat. G
WARNING
Make sure that the back of your head is
supported at eye level by the central area of
the head restraint. If your head is not
supported
correctly by the head restraint, you
could suffer a severe neck injury in the event
of an accident. Never drive if the head
restraints are not engaged and set correctly. G
WARNING
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. G
WARNING
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. G
WARNING
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. G
WARNING
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.
! 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 Seats

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.

and/or the objects could be damaged.
i The head restraints in the front seats are
installed with the NECK-PRO system

possible to remove the head restraints
from the front seats.

in the rear (Cabriolet)
If
the head restraints in the rear compartment
are in the upper position, the soft top cannot
be closed fully. If the head restraint
electronics are malfunctioning and the
adjustment procedure of the soft top is
interrupted leaving the soft top compartment
cover open, you therefore have to lower the
head restraints in the rear compartment
manually.
Lower the head restraints in the rear
compartment manually if:
R the head restraint electronics are
malfunctioning
R the opening or closing procedure of the soft
top is interrupted leaving the soft top
compartment cover open. Cover ; can only be released when the

Important safety notes G
WARNING
The seat belts can only provide protection if
the seat backrest is locked in the upright
position.
The seat backrest must therefore be
locked in the upright position during the
journey. Do not drive the vehicle if the seat
backrest is not locked in the upright position.
If the
Lock Seat Backrest Front Right
or
Lock Seat Backrest Front Left
warning message is displayed in the
multifunction display, then the corresponding
seat backrest is not locked. Carefully slow
down and drive with caution to an area which
is a safe distance from the road. Always
ensure that there is sufficient space behind
the seat backrest and fold the seat backrest
back fully until it engages in the locking
mechanism. The warning message is no longer displayed
once
the seat backrest engages in the locking
mechanism. If both seat backrests are locked
and the warning message continues to be
displayed, have the system checked by a
Mercedes-Benz Center without delay. G
WARNING
Always ensure that no-one can become
trapped or injured by the movement of the
seat.
In a potentially hazardous situation, the
procedure can be interrupted by moving the
seat adjustment switch in the door control
panel or by operating one of the position
buttons of the Memory function.
Folding the seat backrest forward Example: Coupe
The seat moves forwards if you have folded
the backrest forwards and the seat is in the
rear
half of the range. This makes it easier for
passengers to get into and out of the rear
compartment. The head restraint is lowered
simultaneously.
X Pull seat release handle : forwards and
fold the backrest forwards as far as it will
go.
The seat automatically moves to the
foremost
position and the head restraint is
lowered. 110
