y 47In particular, work relevant to safety or on
safety-related systems must be carried out
at a qualified specialist workshop. If this
work is not carried out correctly, the oper-
ating safety of your vehicle may be affec -
ted. There is a risk of an accident and injury .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.
The SRS consists of:
R The SRS warning lamp =
R Belt tensioners
R Belt force limiters
R Airbag s
The SRS warning lamp ==The SRS functions are checked regularly
when you turn on the ignition and when the
engine is running. Malfunctions can therefore
be detected in good time.
The = warning lamp in the instrumen t
cluster lights up when you switch on the igni -tion and goes out 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
triggered in the event of an accident with
heavy braking.
A malfunction has occurred if the =
warning 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 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 firs
tstage the airbag control unit pre-emptively
triggers the belt tensioners.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
If your vehicle is fitted with adaptive dual-
stage front airbags, the front airbag is filled
with enough gas to reduce the risk of injuries
at the first deployment threshold. The front
airbag is only fully inflated if a second thresh-
old is reached within a few milliseconds due
to the control unit having detected further
deceleration.
i
The front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
Criteria for triggering belt tensioners and
airbags
In the first stages of a collision, the sensor in
the airbag control unit evaluates physical
data such as duration, direction and rate of
vehicle deceleration or acceleration in order
to determine whether it is necessary to trig-
ger the belt tensioners and/or airbags.
The belt tensioner and airbag triggerin g
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc-
ess is pre-emptive in nature as the airba g Safety

must be deployed during – and not at the end
of – the collision
.
i Airbags are not deployed in all types of
accident. They are controlled by comple x
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 the collision has taken place do not play
a decisive role in the deployment of an airbag,
nor do they provide an indication of it.
The vehicle may be considerably deformed
without an airbag being deployed if, for exam-
ple, only relatively easily deformable parts
such as the bonnet or wings have been hit and
the required rate of deceleration has not been
reached. It is also possible that airbags ma y
be deployed even though the vehicle is only
slightly deformed if, for example, very rigid
vehicle parts such as the longitudinal mem-
bers are hit in an accident and the rate of
deceleration is sufficient .
Belt tensioners, belt force limiters The front seat belts and the outer seat belts
in the rear are equipped with belt tensioners.
! 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 sea t
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 sea t
belts.
Belt tensioners do not pull occupants back
towards the backrest.
The front belt force limiters are synchronised
with the front airbags, which spread the
forces exerted by the belt force limiters on
the occupant over a greater area.
When the ignition is switched on, the belt ten -
sioner is triggered:
R only if the restraint systems are operational
(the = warning lamp lights up after th e
ignition is switched on and goes out onc e
the engine is running)( Ypage 47)
R for each three-point seat belt in the front of
the vehicle when the belt tongue is
engaged in the buckle

sion if the vehicle decelerates or acceler- Safety

PASSENGER AIRBAG OFF warning lamp
5
The front-passenger seat sensor system for
child restraint systems automatically detect s
whether a special Mercedes-Benz child seat
with automatic child seat recognition has
been fitted. If this is the case, the 5
PASSENGER AIRBAG OFF warning lamp on
the centre console lights up. The front-
passenger front airbag has been disabled. G
Risk of injury
If the 5PASSENGER AIRBAG OFF warn-
ing lamp does not light up when the child
restraint system is fitted, the front-
passenger front airbag has not been disa-
bled. If the front-passenger front airbag is inflated, 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-passenge r
seat.
R Fit a rearward-facing child restraint sys-
tem on a suitable rear seat.
or
R Only use a forward-facing child seat on
the front-passenger seat and move the
front-passenger seat to its rearmost
position.
R Have the automatic child seat recogni-
tion 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, e.g. a
cushion, under the child restraint system.
The entire base of the child restraint system
must always be resting on the seat cushion.
An incorrectly fitted child restraint system
cannot perform its intended protective function in the event of an accident, and
could even lead to injuries.
i The windowbag, the sidebag and the belt
tensioner on the front-passenger side are
still active even if 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, if switched on
R mobile phones
R cards with transponders, e.g. ski passe s
or access passes
as signals from electronic equipment can
cause interference in the automatic child
seat recognition sensor system. This can
cause the system to malfunction. It could
cause the 5PASSENGER AIRBAG OFF
warning lamp to light up even when no child
seat with automatic child seat recognition
has been fitted. The front-passenger front
airbag would not be triggered in an acci-
dent. It may also be that th e
5 PASSENGER AIRBAG OFF warning
lamp does not light up briefly when you turn
the key to position 2in the ignition lock .Safety

Driving safety sys
tems 69ESP
®
cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot overrid e
the laws of physics .
! If the vehicle is to be towed with the front
or rear axle raised, the ignition must be
switched off (key in position 0or 1in the
ignition lock). Application of the brakes by
ESP ®
could otherwise destroy the brake
system on the front or rear axle.
! Vehicles with 4MATIC* may not be towe d
with the front or rear axle raised .
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly .
ESP ®
trailer stabilisin g If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly .
In this situation, ESP ®
assists you and detect s
if the trailer begins to snake. ES P®
slows the
vehicle down by braking and limiting the
engine output until the vehicle/trailer com-
bination has stabilised. Trailer stabilising is active from about
65 km/h. G
Risk of accident
If the road and weather conditions are bad,
trailer stabilising will not be able to prevent
the trailer from lurching or reduce the ris k
of accident. Trailers with a high centre of
gravity can tip over before ESP ®
can detect
this .
Trailer stabilising does not work if ESP ®
is
deactivated or switched off because of a mal-
function .
ETS (Electronic Traction Support) Traction control is part of ES
P®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side.
Traction control remains active when you
deactivate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of
an accident if you drive too fast. Traction
control cannot override the laws of physics .Deactivating/activating ESP
® ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ES P®
in the fol-
lowing situations:
R when using snow chain s
R in deep sno w
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the reason for
deactivation is longer present. ES P®
will
otherwise not be able to stabilise the vehi -
cle if the vehicle starts to skid or a wheel
starts to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R The engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R Traction control is still activated.
R ESP ®
still provides support when you
brake. Safety

Risk of accident
If the v warning lamp in the instrumen t
cluster is permanently lit when the engine
is running, ESP ®
is deactivated or not avail-
able due to a malfunction. The risk of your
vehicle skidding is then increased in certain
situations. You should therefore always adapt your
driving style to suit the prevailing road and
weather conditions.

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 stil l
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 differen t
handling characteristics. Anti-theft systems
