2012 MERCEDES-BENZ SLK ROADSTER airbag disable

How the airbag system works is deter-
mined by the severity of the collision detec-
ted, especially the vehicle deceleration or
acceleration, and the apparent type of acci-
dent:
R
head-on collision
R side impact
R rea rimpact
R overturn
The rate of vehicle deceleratio noraccelera-
tion and the direction of the force are essen-
tially determined by:
R the distribution of forces during the colli-
sion
R the collisio nangle
R the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided
Factors which can only be see nand measured
after a collision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indicatio nofairbag
deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, without an airbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec-
ted and the rate of deceleration is not high.
Conversely, airbags may be deployed even
though the vehicle suffers only minor defor-
mation. This is the case if, for example, very
rigid vehicle parts such as longitudinal body
members are hit, and sufficien tdeceleration
occurs as a result. Airbags
Important safety notes 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 is
released generally does not constitute a
health hazard. The
6SRS warning lamp
lights up.
The airbag installation locations are identified
by the AIRBAG symbol. G
WARNING
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 caused by airbag
deployment:
R all vehicle occupants –inparticular, 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 childre nless than
1.50mt all or unde r12years of age in suit-
able 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 centre of the driver's airbag cover as
possible.
R move the front-passenger seat as far back
as possible. This is especially important if
you have secured a child in a child restraint
system on the front-passenger seat.
R vehicle occupants –inparticular, children
–m ust no tlean their heads into the area of
the window in which the sidebag/headbag
is deployed.
R rearward-facing child restraint systems
must not be fitted to the front-passenger
seat unless the front-passenger fron tair-
bag has been disabled. The front-passenger
front airbag is disabled if a child restraint
system with transponders for automatic
child seat recognition is fitted to the front-
passenger seat. The 4PASSENGER 40

WARNING
If the front-passenger front airbag is not dis-
abled:
R a child secured in a child restraint system
on the front-passenger seat could be seri-
ously and even fatally injured by the front-
passenger fron tairbag deploying .This is
especially a risk if the child is in the imme-
diate vicinity of the front-passenger front
airbag when it deploys.
R never secure a child on the front-passenger
seat in a rearward-facing child restraint sys-
tem.
R always move the front-passenger seat to
the rearmost position if you secure a child
in a forward-facing child restraint system
on the front-passenger seat.
The front-passenger front airbag is not disa-
bled:
R if no child restraint system with a trans-
ponder for automatic child seat recognition
is fitted to the front-passenger seat. In
order to make use of the automatic child
seat recognition, a Mercedes-Benz
approved child seat with a transponder is
necessary.
R if the _ PASSENGER AIRBAG ON indi-
cator lamp lights up for 60 seconds after
the ignition is switched on and the 4
PASSENGER AIRBAG OFF indicator lamp
does not light up.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed 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.
Do not use a rearward-facing child restraint
system for a child on aseat which is already
protected by an airbag.
Automatic child seat recognition on the
front-passenger seat The front-passenger seat sensor system for
child restraint systems detects whether a
special Mercedes-Benzc
hild seat with a
transponder for automatic child seat recog-
nition has been fitted. If so, the _
PASSENGER AIRBAG ON indicator lamp ;
lights up briefly when the ignition is switched
on, and the aPASSENGER AIRBAG OFF
indicator lamp :remains lit. The front-
passenger front airbag is disabled. G
WARNING
If the 4 PASSENGER AIRBAG OFF indica-
tor lamp does not light up when the child
restraint system is fitted, the front-passenger
airbag has not been disabled. If the front-
passenger airbag deploys, 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.

Problems with child seat recognition
Problem Possible causes/consequences and
M Solutions
The
4 PASSENGER
AIRBAG OFF indicator
lamp on the centre con-
sole is lit. As
pecial Mercedes-Benz child seat with a transponder for auto-
matic child seat recognition has been fitted to the front-passenger
seat. The front-passenger airbag has therefore been disabled as
desired. G
Risk of injury
There is no child seat fitted to the front-passenger seat. Automatic
child seat recognition is malfunctioning.
When you switch on the ignition, it is also possible that:
R the 6 SRS warning lamp lights up.
R The a PASSENGER AIRBAG OFF indicator lamp does not
light up briefly.
R The _ PASSENGER AIRBAG ON indicator lamp does not light
up, or lights up and does not go out after 60 seconds.
X Remove electronic equipment from the front-passenger seat,
e.g.
R laptop
R mobile phone
R cards with transponders, such as ski passes or access cards
If the 4 PASSENGER AIRBAG OFF indicator lamp is still lit:
X Visit a qualified specialist workshop. Suitable positioning of the child restraint systems

seat recognition to the front-passenger seat:
X Move the front-passenger seat to its highest and rearmost position.
