have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
Airbags Airbag deployment slows down and restricts
the movement of the vehicle occupant.
If the airbags are deployed, you will hear a
bang and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that escapes
does not generally constitute a health hazard.
The 6 warning lamp lights up.
The AIRBAG identification indicates the loca-
tion of the airbags. G
Risk of injury
Airbags provide additional protection; they
are not, however, a substitute for seat belts.
Observe the following notes to reduce the risk
of serious or even fatal injury if an airbag is
deployed:
R all vehicle occupants ― in particular preg-
nant women ― must wear their seat belt
correctly at all times and lean back against
the backrest, which should be positioned
as close to the vertical as possible. The
head restraint must support the back of the
head at about eye level.
R always secure children less than 1.50 m tall
or under 12 years of age in suitable child
restraint systems.
R all vehicle occupants must select a seat
position that is as far away from the airbag
as possible. The driver's seat position must
allow the vehicle to be driven safely. The
driver's chest should be as far away from
the middle of the driver's front airbag cover
as possible. R
move the front-passenger's seat as far
back as possible, especially if a child is
secured in a child restraint system on the
seat.
R vehicle occupants – in particular, children
– must not lean their head into the area of
the window in which the sidebag/window-
bag is deployed.
R rearward-facing child restraint systems
must not be fitted to the front-passenger's
seat unless the front-passenger front air-
bag has been disabled. The front-passenger
front airbag of a vehicle fitted with auto-
matic child seat recognition* is only disa-
bled when a child restraint system with
automatic child seat recognition is fitted to
the front-passenger's seat. The
4 PASSENGER AIRBAG OFF warning
lamp must be continuously lit.
If the front-passenger's seat of your vehicle
does not have automatic child seat recog-
nition*, or your rearward-facing child
restraint system does not have automatic
child seat recognition, children must be
secured in a child restraint system on a
suitable seat in the rear. If you secure a
forward-facing child restraint system to the
front-passenger's seat, you must move the
front-passenger's seat as far back as pos-
sible.
R make sure there are no heavy or sharp-
edged objects in pockets of clothing.
R do not lean forwards, e.g. over the cover of
the driver's/front-passenger front airbag,
particularly when the vehicle is in motion.
R do not put your feet on the dashboard.
R only hold the steering wheel by the rim. This
allows the airbag to inflate fully. You could
be injured if the airbag is deployed and you
are holding the inside of the steering wheel.
R do not lean on the doors from inside the
vehicle. Occupant safety

lamp is not lit.

sponding warning sticker on the dashboard
and on both sides of the sun visor on the front-
passenger side.
Information about recommended child
restraint systems is available at any
Mercedes-Benz Service Centre.
Automatic child seat recognition on the
front-passenger seat*
If your vehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. It is visible when
you open the front-passenger door. The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Benz child seat with auto-
matic child seat recognition has been fitted.
In such cases, 4PASSENGER AIRBAG
OFF indicator lamp :lights up. The front-
passenger airbag is disabled. G
Risk of injury
If the 4 PASSENGER AIRBAG OFF warning
lamp does not light up when the child restraint
system is fitted, the front-passenger front air-
bag has not been disabled. If the front-
passenger front airbag is deployed, the child
could be seriously or even fatally injured. Proceed as follows:
R
do not use a rearward-facing child restraint
system on the front-passenger seat.
R fit a rearward-facing child restraint system
on a suitable rear seat.
or
R only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat to its rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions correctly, never place objects (such as
a cushion) under the child restraint system.
The entire base of the child restraint system
must always rest on the seat cushion. An
incorrectly fitted child restraint system can-
not perform its intended protective function
in the event of an accident, and could lead to
injuries.
i The windowbag, the sidebag and the belt
tensioner on the front-passenger side are
still active even when the front-passenger
front airbag is disabled. G
Risk of injury
Do not place items of electronic equipment
on the front-passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This could lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF warning lamp
to light up without there being a child seat
with automatic child seat recognition fitted.
This means that the front-passenger airbag
does not deploy during an accident. It is also Occupant safety
