Never tamper with electronic components
and their software.
SRS (Supplemental Restraint System)
The SRS reduces the risk of occupants com-
ing into contact with the vehicle's interior in
the event of an accident. It can also reduce
the forces to which occupants are subjected
during an accident.
The SRS consists of:
R the 6 SRS warning lamp
R belt tensioners
R belt force limiters
R airbags
The 6 6SRS warning lamp The SRS functions are checked regularly
when you turn on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The
6 warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or not be
deployed in the event of an accident with
heavy braking.
A malfunction has occurred if the 6warn-
ing lamp:
R does not light up when you switch on the
ignition
R does not go out after the engine has been
running for a few seconds
R lights up again once the engine is running
In this case, have SRS checked immediately
at a qualified specialist workshop. Triggering of belt tensioners, belt force
limiters and airbags In the event of a collision, the sensor in the
airbag control unit evaluates important phys-
ical data such as duration, direction and force
of the vehicle deceleration or acceleration.
Based on the evaluation of this data and
depending on the vehicle's rate of longitudi-
nal deceleration in a collision, in the first
stage the airbag control unit pre-emptively
triggers the belt tensioners.
i
The front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
Your vehicle has adaptive, dual stage front
airbags. When the first activation threshold is
reached, the front airbag is filled with enough
propellant gas to reduce the risk of injuries.
The front airbag is only fully inflated if a sec-
ond threshold is reached within a few milli-
seconds, due to the control unit having detec-
ted further deceleration.
Criteria for triggering belt tensioners and
airbags
In the first stage of a collision, the airbag con-
trol unit evaluates the duration and direction
of vehicle acceleration or deceleration in
order to determine whether it is necessary to
trigger the belt tensioner and/or airbag.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc-
ess is pre-emptive in nature as the airbag
must be deployed during – and not at the end
of – the collision.
i Airbags are not deployed in all types of
accidents. They are controlled by complex
sensor technology and evaluation logic.
This process is pre-emptive in nature as
airbag deployment must take place during
the impact and must be adapted to provide Occupant safety

page 43). This means that there is not a
child restraint system with automatic child
seat recognition* fitted to the front-
passenger seat or that a child restraint sys-
tem with automatic child seat recognition*
has been fitted to the front-passenger seat
incorrectly.
Driver's knee airbag
i The driver's knee airbag is only available
in certain countries.
The driver's knee airbag can help reduce the
risk of injury to the knees, thighs and lower
legs. Driver's knee airbag
:is always deployed
along with the driver's front airbag and
inflates underneath the steering column.
Sidebags G
Risk of injury
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Benz vehicles.
The seat covers must have a special tear seam
for sidebags. Otherwise, a head/thorax air-
bag cannot deploy correctly and would fail to
provide the intended protection in the event
of an accident. Appropriate seat covers can
be obtained from a Mercedes-Benz Service
Centre. G
Risk of injury
Sensors to control the airbags are located in
the doors. Therefore, do not make any modi- fications to the doors or door trims, e.g. ret-
rofitting loudspeakers. Damage to the doors
can affect operation of the sidebags.
The purpose of sidebag deployment is to
enhance the level of protection for the thorax
(but not the head, neck or arms) of the vehicle
occupants on the side of the vehicle on which
the impact occurs. Front sidebags
:and rear sidebags*;
deploy next to the outer seat cushion. 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 accelera-
tion, e.g. in a side impact
R independently of the seat belt use
R independently of the front airbags
R independently of the belt tensioners
Windowbags
The purpose of the windowbags is to enhance
the level of protection for the head (but not
chest or arms) of the vehicle occupants on
the side of the vehicle on which the impact
occurs.
The windowbags are integrated into the side
of the roof frame and run from the front door
(A-pillar) to the rear door (C-pillar). Occupant safety

PASSENGER AIRBAG OFF warning
lamp is not lit.
To draw attention to this danger, a corre-
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

ple, if someone breaks the side windows of
your vehicle or reaches into the vehicle's inte-
