You must not tamper with electronic compo-
nents or 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 6 SRS warning lamp 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 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
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 6SRS
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 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

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. For example, this is the
case if very rigid vehicle parts such as longi-
tudinal body members are affected and suf-
ficient deceleration occurs as a result.
Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
! Do not engage the seat belt tongue in the
buckle on the front-passenger seat if the
seat is not occupied. The belt tensioners could otherwise be triggered in an acci-
dent.
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 a pro-
portion of the deceleration forces exerted on
the occupant over a greater area.
The front seat belts have an automatic com-
fort-fit feature. This reduces the retraction
force of the seat belts, which results in
increased seat belt comfort.
The belt tensioners cannot be triggered when
the ignition is switched on unless:
R the restraint systems are operational; see
6 SRS warning lamp.
R the belt tongue is engaged in the buckle on
each lap-shoulder belt in the front of the
vehicle.
Depending on the type and severity of an
accident, the belt tensioners may be trig-
gered:
R in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of impact
R in the event of a side impact if the vehicle
is subjected to high lateral acceleration/
deceleration
R in certain situations if the vehicle over-
turns, and the system determines that it
can provide additional protection
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 38

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 if the front-passenger front
airbag is disabled by the automatic child-
seat recognition on the front-passenger
seat. G
Risk of injury
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 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 front air-
bag does not deploy during an accident. It is
also possible that the 4PASSENGER AIR-
BAG OFF warning lamp will not light up briefly
if you turn the key in the ignition lock to posi-
tion 2.

R
Under no circumstances should you deac-
tivate ESP ®
.
R When pulling away, only depress the accel-
erator pedal as far as is necessary.
R Adapt your driving style to the prevailing
road and weather conditions.
The vehicle may otherwise begin to skid.
If you drive too fast, ESP ®
cannot reduce the
risk of an accident. ESP ®
cannot override 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 towed
with the front or rear axle raised.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS (Electronic Traction Support) Traction control is part of ESP
®
.
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.
Activating/deactivating ESP ®ESP
®
is activated automatically when the
engine is running. It may be best to deactivate ESP
®
in the fol-
lowing situations:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts
to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels produce a cutting effect for better
traction.
R traction control is still activated.
R ESP ®
still provides support when you
brake.
i If ESP ®
is deactivated and one or more
wheels start to spin, the ÷warning lamp
in the instrument cluster flashes. In such
situations, ESP ®
will not stabilise the vehi-
cle.
X To deactivate: (Ypage 224).
The å warning lamp in the instrument
cluster lights up. G
Risk of accident
If the å warning lamp in the instrument
cluster lights up when the engine is running,
ESP ®
is deactivated or is unavailable due to a
malfunction. The risk that your vehicle may
start to skid then increases in certain situa-
tions.
Always adapt your driving style to the prevail-
ing road and weather conditions. Driving safety systems

To activate/deactivate: activate or deac-
tivate PRE-SAFE ®
Brake in the on-board
computer (Y page 224).
After activation, the Äsymbol is dis-
played on the left in the driver display.
Vehicles with COMAND and a navigation sys-
tem*: the radar sensor system is switched off
automatically in the vicinity of radio telescope
facilities (Y page 411).
For PRE-SAFE ®
Brake to assist you when driv-
ing, the radar sensor system must be
switched on and operational.
PRE-SAFE ®
Brake does not always clearly
identify complex traffic situations properly.
You can terminate the intervention of PRE-
SAFE ®
Brake in a non-critical driving situation
at any time if:
R an acoustic and visual warning occurs
R the vehicle brakes gently
To end this you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal.
The braking intervention of PRE-SAFE ®
Brake
is ended automatically if:
R you manoeuvre to avoid the obstacle.
R you drive slower than approximately
15 km/h.
R there is no longer an obstacle detected in
front of your vehicle.
R there is no longer any danger of a collision.
i While Distronic Plus is activated, PRE-
SAFE ®
Brake remains passive.
Following a collision or crash-related damage
to the front end of the vehicle, have the con-
figuration and operation of the radar sensors
checked. Choose a qualified specialist work-
shop for this which has the necessary spe-
cialist knowledge and tools for the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose. Anti-theft systems
