even fatal injury.
Make sure that no parts of the body are in the closing area. To stop the closing process, release
the switch or push the switch again to reopen the side window.

Soft top (Roadster)
Important safety notes
GWARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after a short
time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is a risk of injury.
Always open or close the soft top completely.
!Never sit on the soft top or store heavy
objects on it. You will otherwise damage the
vehicle soft top and soft-top covers.
!When opening and closing the soft top,
make sure that:
Rthere is sufficient clearance above it, as the
soft top swings upwards
Rthere are no objects on the soft top or the
soft-top covers to the side
Rthe fabric is not dirty, wet or frozen
Rthe outside temperature is above -10 †
You could otherwise damage the soft top as
well as other parts of the vehicle.
Take the height of the vehicle into account when
opening and closing the soft top (
Ypage 291).
Make sure that the soft top is dry and clean
before opening or closing it. Otherwise, water or
dirt could enter the vehicle interior or trunk.
You can open or close the soft top:
Rwhen the vehicle is stationary or
Rwhen you do not exceed a speed of 31 mph
(50 km/h) (max. 37 mph (60 km/h), to avoid
interrupting the closing process while slightly
exceeding this speed)
If there is a strong head wind, it may not be pos-
sible to close the soft top fully. In order to close
the soft top fully, reduce your speed or stop the
vehicle in accordance with the traffic condi-
tions.
For safety reasons, Mercedes-Benz recom-
mends that you only open or close the soft top
when the vehicle is stationary.
If the soft top does not open or close fully, the
soft-top hydraulics are depressurized and the
soft top is lowered:
Rafter approximately 7 minutes when the igni-
tion is switched on
Rafter about
20 seconds if the ignition is switched off

Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The seats can still be adjusted when there is no
SmartKey in the ignition lock.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
Observe the safety notes on "Air bags"
(
Ypage 45) and "Children in the vehicle"
(Ypage 55).
84Seats
Seats, steering wheel and mirrors

GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
For safety reasons, seat fore-and-aft adjustment
on electrically adjustable seats is only possible
for a maximum of two seconds when the vehicle
is in motion. The seat fore-and-aft adjustment
can then no longer be set.
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem.
GWARNING
If head restraints are not adjusted correctly,
they cannot provide protection as intended.
There is an increased risk of injury in the head
and neck area, e.g. in the event of an accident or when braking.
Before driving off, make sure for every vehicle
occupant that the center of the head restraint
supports the back of the head at about eye
level.
Using the fore-and-aft adjustment, adjust the
head restraint so that it is as close as possible to
your head.
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatalinjury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
!To prevent damage to the seats and the seat
heating, observe the following notes:
RDo not spill liquids onto the seats. Dry the
seats as soon as possible if liquid does get
spilled on the seats.
RIf the seat covers are damp or wet, do not
switch on the seat heating. Also, do not use
the seat heating to dry the seats.
RClean the seat covers as recommended;
see keyword "Care".
RDo not transport heavy loads on the seats.
Do not place pointed objects on the seat
cushions such as knives, nails or tools.
Where possible, use the seats only for car-
rying passengers.
RWhen operating the seat heating, do not
cover the seats with insulating materials,
e.g. blankets, coats, bags, protective cov-
ers, child seats or booster seats.
!Make sure that there are no objects in the
footwell under or behind the seats when mov-
ing the seats back. There is a risk that the
seats and/or the objects could be damaged.

Seat heating and seat ventilation
Switching the seat heating on/off
GWARNING
Repeatedly switching on the seat heating can
cause the seat cushion and backrest pads to
become very hot. The health of persons with
limited temperature sensitivity or a limited
ability to react to high temperatures may be
affected or they may even suffer burn-like
injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.
!Heat accumulation can occur if the seat
heating is switched on and there are objects
or underlays placed on the seats, e.g. seat
cushions or child seats.
This can lead to damage to the seat surface.

Problems with the seat heating or seat ventilation
ProblemPossible causes/consequences and MSolutions
The seat heating or seat
ventilation has switched
off prematurely or can-
not be switched on.The on-board voltage is too low because too many electrical consum-
ers are switched on.
XSwitch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating or seat
ventilation will switch back on automatically.
