WARNING
Modifications to or work performed incor-
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 force limiters 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 force being sufficien tto trig-
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 consists of:
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 occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
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 a few 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
a high rate of vehicle deceleration.
A malfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignition is switched on.
R the engine is running and the 6SRS
warning lamp does not go out after a few
seconds.
R the engine is running and the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at a qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of a collision, 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 front belt tensioners can only be trig-
gered if the seat belt tongues on the front
seats are correctly engaged in the seat belt
buckles.
If there is an even higher rate of vehicle decel-
eration or acceleration in a longitudinal 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 Occupant safety
47Safety Z 

resulting in the force exerted on the occupant
being distributed over a greater area.
The beltt ensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 47).
R the belt tongue is engaged in the buckle on
each of the three-poin tseat belts in the
front.
The belt tensioners on the outside seats in the
rear compartment are triggered independ-
ently of the lock status of the seat belts.
The belt tensioners are triggered depending
on the type and severity of an accident:
R if, in the event of a head-on or rear-end col-
lision, the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R if, in the event of a side impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in a lateral direc-
tion
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. 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 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.
! 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. Children in the vehicle
Child restraint systems
Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R children less than 1.50 m tall and under
twelve years of age must always be secured
in special child restraint systems on a suit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R do not secure children less than 1.5 0mtall
or under twelve years of age on the front-
passenger seat .Exception: the vehicle is
equipped with automatic child sea trecog-
nition on the front-passenger seat and the
child is secured in a child restraint system
with transponders for automatic child seat
recognition.
R if you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of a sudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to a suitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The Children in the vehicle

board. The key must be inside the vehicle.
The alarm is switched off. Tow-away protection
An audible and visual alarm is triggered if your
vehicle's angle of inclination is altered while
tow-away protection is primed. This occurs if
the vehicle is jacked up on one side, for exam-
ple.
X To prime: lock the vehicle with the key or
KEYLESS-GO.
Tow-away protection is primed after
approximately 30 seconds.
X To deactivate: unlock the vehicle with the
key or KEYLESS-GO.
Tow-away protection is deactivated auto-
matically.
To prevent a false alarm, deactivate tow-away
protection manually if your vehicle:
R is being transported
R is being loaded onto a ferry or car trans-
porter, for example
R is parked on a movable surface, e.g. in a
split-level garage

R the vehicle is unlocked again.
R a door is opened and closed again.
R the vehicle is locked again. Interior motion sensor
If the interior motion sensor is primed, a vis-
ual and audible alarm is triggered if move-
ment is detected in the vehicle interior while
the vehicle is locked. This occurs if someone
reaches into the vehicle interior, for example.
To activate:
X Make sure that:
R
the side windows are closed.
R the sliding sunroof/panorama sliding
sunroof is closed.
R there are no objects, e.g. mascots, hang-
ing on the rear-view mirror or on the grab
handles on the roof trim.
This will prevent false alarms.
X Lock the vehicle with the key or KEYLESS-
GO.
The interior motion sensor is primed after
approximately 30 seconds. Anti-theft systems
