followed. These instructions are available
from any authorized Mercedes-Benz
Center.
R Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also, refer them to the
applicable section in the Operator's Manual.
Air bags
Important safety notes
GWARNING
Air bags are designed to reduce the potential
of injury and fatality rates in certain
situations:
R frontal impacts (driver's and front-
passenger front air bags and knee bags)
R side impacts (head bags and side impact air
bags)
However, no system available today can
completely eliminate injuries and fatalities.
When the air bags are deployed, a small
amount of powder temporarily comes out of
the air bags. This powder generally does not
constitute a health hazard and does not
indicate that there is a fire in the vehicle. In
order to prevent potential breathing
difficulties, you should leave the vehicle as
soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle, then get fresh air by opening a side
window or door.
GWARNING
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with your back against the
backrest. Fasten your seat belt and make sure
that it is correctly positioned on your body.
As the air bag inflates with considerable
speed and force, a proper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at a safe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag as it
inflates with great force instantaneously:
R sit with the seat belt fastened correctly and
in a position that is as upright as possible
with your back against the backrest.
R move the driver's seat as far back as
possible, still permitting proper operation
of vehicle controls. The distance from the
center of the driver's chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches (25 cm) or more.
You should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-Benz Center.
R do not lean your head or chest close to the
steering wheel or dashboard.
R only hold the steering wheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severity of
hand/arm injury when the driver front air
bag inflates.
R adjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
R Occupants, especially children, should
never place their bodies or lean their heads
in the area of the door or the seat where the
head bag or side impact air bag inflates.
This could result in serious injuries or death
should the head bag or side impact air bag
be deployed. Always sit as upright as38Occupant safetySafety
Example: Coupe
Head bags : deploy in the area of the side
window.
They are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R if the system determines that the vehicle
occupants are offered additional
protection to that provided by the seat belt
R independently of the use of the seat belt
R independently of the ETDs
R on the driver's side and passenger side, in
the event of a vehicle rollover and if the
system determines that air bag deployment
can offer the vehicle occupants additional
protection to that provided by the seat belt
R independently of the front air bags
Head bags : will not deploy in side impacts
which do not exceed the system's preset
deployment thresholds for lateral
acceleration/deceleration. You will then be
protected by the fastened seat belt.
If the OCS has classified the front-passenger
seat as unoccupied and the front-passenger
seat belt is not fastened, the head bag on the
passenger side will not deploy. The head bag
on the front-passenger side will deploy if the
front-passenger seat belt is fastened,
regardless of whether the front-passenger
seat is occupied or not.
Occupant Classification System
(OCS)
How the occupant classification
system works
The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenger seat using a weight sensor. The
front-passenger front air bag and the front-
passenger knee bag are deactivated
automatically for certain weight categories.
The 45 indicator lamp shows you the
current status. When the 45 indicator
lamp is illuminated, the front-passenger front
air bag and the front-passenger knee bag are
deactivated.
The system does not deactivate:
R the front-passenger side impact air bag
R the front-passenger head bag
R the Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in a position that is as upright as possible
with their back against the seat backrest
R with their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by
leaning on armrests), OCS may not be able to
approximate the occupant's weight category.
To establish whether the front passenger is
being properly detected, both the driver and
the front passenger should pay attention to
the 45 indicator lamp.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at an
authorized Mercedes-Benz Center.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.

Side windows
Important safety notes
GWARNING
When opening and closing the side windows,
make sure that nobody can be injured by the
opening or closing procedure.
The side windows are equipped with
automatic operation and anti-entrapment
Side windows75Opening/closingZ
features. If, in automatic operation mode, a
side window encounters an obstruction that
blocks its path, the anti-entrapment feature
will stop the side window and open it slightly.
The side windows operate differently when
the switch is pulled and held. These details
can be found in the "Closing a blocked side
window" section in this chapter.
The closing of the side windows can be
immediately halted by releasing the switch or,
if the switch was pulled past the resistance
point and released, by pressing or pulling the
respective switch.
If a side window encounters an obstruction
that blocks its path when you are closing the
side windows by pressing and holding the
& button on the SmartKey, the anti-
entrapment feature will not operate.GWARNING
Do not keep any part of your body up against
the window pane when opening a window. The
downward motion of the pane may pull that
part of your body down between the window
pane and the door frame and trap it there. If
there is a risk of entrapment, release the
switch and pull it to close the window.
Observe the important safety notes in the
"Children in the vehicle" section (Y page 51).

Soft top (Roadster)
Important safety notes
GWARNING
Only drive with the soft top fully open or
closed.
If the soft top does not open or close fully, the
soft-top hydraulics are depressurized and the
soft top is lowered:
R after about seven minutes if the ignition is
switched on
R immediately if the ignition is switched off
A warning tone sounds shortly beforehand.
The Top lowering message appears in the
multifunction display..

during the journey and cause you to lose
control of your vehicle. You and/or other
persons could be injured as a result.
You can open or close the soft top:
R if the vehicle is stationary or
R if the speed does not exceed 30 mph
(50 km/h)
If there is a strong head wind, it may not be
possible to close the soft top fully. In this
case, reduce speed or stop in order to close
the soft top fully.
For safety reasons, Mercedes-Benz
recommends that you only open or close the
soft top when the vehicle is stationary.
! Never sit on the soft top when it is closed
or store heavy objects on it. You will
otherwise damage the soft top of the
vehicle.
