WARNING
Modifications to or work performe dincor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, beltt en-
sioners, belt forc elimiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an acciden tdespite
the deceleration forc ebeing sufficien ttotrig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with elec-
tronic components or their software. SRS (Supplemental Restraint System)
Introduction SRS consist
sof:
R the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS reduces the risk of occupant scoming
into contact with the vehicle's interior in the
event of an accident .Itcan also reduce the
effect of the forces to which occupant sare
subjected during an accident.
SRS warning lamp SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than afew seconds
after the engine is started. G
WARNING
If SRS is malfunctioning, individual systems
may be activated unintentionally or may not
be triggered in the event of an accident with
ah igh rate of vehicle deceleration.
Am alfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignition is switched on.
R the engine is runnin gand the 6SRS
warning lamp does not go out after afew
seconds.
R the engine is runnin gand the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at aq ualified specialist workshop. Mercedes-
Benz recommends that you use aMercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
aq ualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of
acollision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage.
i The belt tensioners can only be triggered
if the seat belt tongues are correctly
engaged in the seat belt buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in alongitudinal direc-
tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event
of ac ollision. In the first deployment stage, Occupant safety

the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfil their
protective function and must be replaced.
Consult aMercedes-BenzS ervice Centre. Belt warning for driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is areminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, ther emay be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tonec eases when the driver and
the fron tpassenger have fastened their seat
belt.
For certain countries only: regardless of
whether th edriver or th efront passenger
have fastened their seat belts, the 7seat
beltw arning lamp light supfor six seconds
after th eengineiss tarted. It then goes out if
th ed river and th efront pa ssenger have fas-
tene dtheir seat belts.

an accident, pulling them close against the
body.
Belt tensionersdon ot correct incorrects eat
positions or incorrectly fastened seat belts.
Belt tensionersdon ot pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with abelt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the front seats are
synchronised with the front airbags. These
take on apart of the deceleration force. Thus,
the force exerted on the occupant is distrib-
uted over agreater area.
The belt tensionersc an only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 39).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in the
front.
The belt tensionersont he seats in the rear
compartmenta re triggeredindependently of
the lock status of the seat belts. The beltt
ensioners are triggered depending
on the type and severit yofanaccident:
R if, in the event of ahead-on or rear-en dcol-
lision, the vehicle decelerates or acceler-
ates rapidly in alongitudinal direction dur-
ing the initial stages of the impact
R if, in the event of aside impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in alateral direc-
tion
R Cabriolet: in certain situation sifthe vehicle
overturns and the system determines that
it can provide additional protection.
If the airbags are deployed, you will hear a
bang, and asmall 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. G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at aqualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners .Any Mercedes-Benz
Service Centr ecan provide details of these
regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident. 50

checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, under the child
restraint system. The entire base of the child
restraint system must alwaysr est on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could leadtoi njuries.

WARNING
Do not place electronic devices 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 can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up without there being achild
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
It is also possible that the 6SRS warning
lamp lights up and/or the 4PASSENGER
AIRBAG OFF indicator lamp does not light up briefly when you turn the key in the ignition
lock to position 2.
ISOFIXc hild seat securing system for
the rear seats ISOFIXisas
tandardised securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two ISOFIX
child restraint systems are fitted on the left
and right of the rear seats.
Mercedes-Ben zrecommends the use of ISO-
FIX child restraint systems listed on
(Y page 59) together with the insertion
guides included. Using insertion guides
makes it easier to fit ISOFIXc hild restraint
systems. G
WARNING
Ac hild restraint system secured by the ISOFIX
child seat securing system does not provide
sufficient protection for children weighing
more than 22 kg. For this reason, do not
secure children weighing more than 22 kg in
ac hild restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system using athree-point seat belt. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fittingac hild restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
For reasons of safety, only use child restraint
systems with the ISOFIX child seat securing
system on the rear seats.
We recommendt hat you use the ISOFIX child
restraint systems that have been recommen-
ded for Mercedes-Benz. 54
