Occupant safety
33carry out any modifications on the restraint
systems.
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 1 warning lamp
R belt tensioners
R belt force limiters
R airbags
The 1 1warning lamp The SRS functions are checked regularly
when the key is in position
1or 2in the igni-
tion lock. Malfunctions can therefore be
detected in good time. The
1 warning lamp in the instrument
cluster lights up
R for approximately four seconds when you
turn the key to position 1in the ignition
lock.
This indicates that the restraint systems
are operational.
R permanently when you turn the key to posi-
tion 2in the ignition lock.
This indicates that the 1warning lamp
is operational. 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 1
warning lamp:
R does not go on when you turn the key to
position 1in the ignition lock.
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 immedi-
ately 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 belt tensioners can only be triggered
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.
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 Safety

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
calculated, additional protection for the
vehicle occupants. Not all airbags are
deployed in an accident.
The different airbag systems work inde-
pendently of each other. However, the
deployment of each individual system will
depend on the type of accident determined
by the control system in the first stages of
the collision (head-on collision, side impact
and overturn) and the extent of the acci-
dent (in particular, the vehicle's rate of
deceleration or acceleration).
The rate of vehicle deceleration or accelera-
tion and the direction of the force are basi-
cally determined by:
R the distribution of forces during the colli-
sion
R the collision angle R
the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided, e.g. the other vehi-
cle
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indication of it.
The vehicle may be deformed significantly,
e. g. on the bonnet or the wing, without an
airbag being deployed. This is the case if only
parts which are relatively easily deformed are
affected and the necessary deceleration does
not occur. Conversely, airbags may be
deployed even though the vehicle suffers only
minor deformations. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are affected and suf-
ficient deceleration occurs as a result.
Belt tensioners, belt force limiters The front seat belts and the outer seat belts
in the rear are equipped with belt tensioners
and belt force limiters.
!
Do not engage the seat belt tongue in the
buckle on the front-passenger seat if the
seat is not occupied. Otherwise the belt tensioner could be activated in an emer-
gency.
If the seat belt is also equipped with a belt
force limiter, the force exerted by the seat
belt on the seat occupant is reduced.
Belt tensioners tighten the seat belts in an
accident, pulling them close against the body.
i Belt tensioners do not correct incorrect
seat positions or incorrectly fastened seat
belts.
Belt tensioners do not pull occupants back
towards the backrest.
The front belt force limiters are synchronised
with the front airbags, which distribute the
forces exerted by the belt force limiters on
the occupant over a greater area.
The seat belts have an automatic comfort-fit
feature. This reduces the retraction force of
the seat belts, which results in increased seat
belt comfort.
When the ignition is switched on, the belt ten-
sioner is triggered:
R only when the restraint systems are opera-
tional (the 1warning lamp lights up
when the key is turned to position 1in the Safety

sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of impact
R in certain situations if the vehicle over-
turns, and the system determines that it
can provide additional protection
R on the front-passenger side only if the
front-passenger seat is occupied and the
belt tongue is engaged in the buckle
If the belt tensioners are triggered you will
hear a bang, which will not cause any harm to
your hearing, and a small amount of powder
may also be released. The 1warning lamp
lights up. G
Risk of injury
The belt tensioners in the rear only function
if they can pull the buckles downwards
without obstruction. They must not be
restricted in any way. For this reason, do
not hold the belt buckles and do not place
any objects under the belt buckles. Other- wise, the tensioning of the belt by the
buckle is restricted or will not function and
will not provide any additional protection.
G
Risk of injury
If the seat belt tensioners have been trig-
gered, they provide no additional protec-
tion in the event of another accident. There-
fore, have belt tensioners which have been
triggered replaced at a qualified specialist
workshop.
Comply with safety regulations when dis-
posing 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, which will not cause any harm to your
hearing, and a small amount of powder may
also be released. The
1warning lamp
lights up. 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 air-
bag 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 pos-
sible. 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 air-
bag as possible. The driver's seat posi-
tion 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 seat as far
back as possible, especially if a child is Safety

Risk of injury
If the front-passenger front airbag is not
disabled:
R a child secured in a child restraint system
on the front-passenger seat could be
seriously and even fatally injured by the
front-passenger front airbag deploying.
This is especially a risk if the child is in
the immediate vicinity of the front-
passenger front airbag when it deploys.
R a child must never be secured on the
front-passenger seat in a rearward-facing
child restraint system. Only secure a
rearward-facing child restraint system on
a suitable rear seat.
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 dis-
abled:
R on vehicles without automatic child seat
recognition on the front-passenger seat.
R in vehicles with automatic child seat rec-
ognition on the front-passenger seat, if
there is no child restraint system with automatic child seat recognition fitted to
the front-passenger seat.
R on vehicles with automatic child seat rec-
ognition on the front-passenger seat if
the 5 PASSENGER AIRBAG OFF warn-
ing lamp is not lit.
To draw attention to this danger, there is an
appropriate warning sticker on the dash-
board as well as 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.

Risk of injury
If the 5 PASSENGER AIRBAG OFF warn-

restraint system is fitted, the front-
passenger front airbag has not been disa-
bled. If the front-passenger front airbag is
deployed, the child could be seriously or
even fatally injured. Safety

Risk of accident
If the v warning lamp in the speedom-
eter is continuously lit when the engine is
running, ESP ®
is deactivated or not availa-
ble due to a malfunction. There is an
increased risk of your vehicle skidding in
certain situations.
You should always adapt your driving style

tion)
EBV monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability under braking. G
Risk of accident
If EBV is malfunctioning, the brake system
is still available with full brake boosting
effect. However, the rear wheels can still
lock, e.g. under full braking. This could
cause you to lose control of your vehicle
and cause an accident. You should there-
fore adapt your driving style to the different
handling characteristics. 4ETS (Electronic Traction System)
4ETS makes it possible to pull away or accel-
erate on a slippery surface. It brakes the
wheels individually if they start to spin.
The v warning lamp in the speedometer
lights up briefly when the engine is started.
This indicates that the warning lamp is opera-
tional.
4ETS switches itself on if at least one tyre has
reached its grip limit. It brakes wheels indi-
vidually until enough traction has been
attained.
4ETS remains active when you deactivate
ESP ®
.
4ETS is no longer active above a speed of
about 60 km/h.
The v warning lamp in the speedometer
flashes at any speed if at least one tyre has
exceeded its tyre grip limit. Safety

Risk of accident
When driving on a firm road surface, never
drive with the differential locks engaged.
Never drive through tight corners with the
differential lock on the front axle engaged.
When differential locks are engaged, the
vehicle's steerability is greatly impaired
and the risk of accident thereby increases.
Do not engage or disengage the differential
locks while cornering. The vehicle motion
could otherwise be jerky. You could lose
control of the vehicle as a result and cause
an accident. If you select a differential lock, ABS, 4ETS,
