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 + warning lamp
R belt tensioners
R belt force limiters
R airbags
The + + warning lamp The 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
+ 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 +warn-
ing 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 airbag control
unit evaluates important physical data such
as duration, direction and force of the vehicle
deceleration or acceleration. Based on the
evaluation of this data and in the event of lon-
gitudinal deceleration in a collision, the airbag
control unit pre-emptively triggers the belt
tensioners, depending on the rate of deceler-
ation, in the first stage.
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 essen-
tially 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 collides, e.g. the other vehicle
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 front seat belts and the outer seat belts
in the second row are equipped with belt ten-
sioners. The front seat belts are also fitted
with belt buckle 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.
When the ignition is switched on, the belt ten-
sioners/belt buckle tensioners cannot be
triggered unless:
R the restraint systems are operational; see
+ 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/belt buckle ten-
sioners may be triggered:
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 36

the
4 PASSENGER AIRBAG OFF warning
lamp is not lit.
To alert you to this danger, a corresponding
warning sticker is located on the dashboard
and 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.
Automatic child seat recognition on the
front-passenger seat
If your vehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. It is visible when
you open the front-passenger door.
The warning lamp 3
is located on the centre
console. The sensors for the automatic child seat rec-
ognition on the front-passenger seat detects
whether a special Mercedes-Benz child seat
with automatic child seat recognition has
been fitted. In such cases, 4PASSENGER
AIRBAG OFF warning lamp :lights up. The
front-passenger front airbag is disabled. G
Risk of injury
If the 4 PASSENGER AIRBAG OFF warning
lamp does not light up when the child restraint
system is fitted, the front-passenger front air- bag has not been disabled. If the front-
passenger front airbag is deployed, 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-passenger seat.
R fit a rearward-facing child restraint system
on a suitable rear seat.
or
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
3 Vehicles without automatic child seat recognition in the front-passenger seat: the warning lamp lights up

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 will not deploy during an accident. It is
also possible that the 6SRS warning lamp
lights up and/or the 4PASSENGER AIR-
BAG OFF warning lamp does not light up
briefly when you turn the key in the ignition
lock to position 2.

effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 25 km/ho r if braking is assisted by BAS,
the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an
even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically. If the
brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 81).ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
When ESP ®
intervenes, the dwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the d warning lamp in the instrument
cluster flashes, proceed as follows: R
do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator pedal as far as
necessary when pulling away.
R adapt your driving style to suit the prevail-
ing road and weather conditions.
Otherwise, the vehicle could skid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! Only operate the vehicle briefly (for a max-
imum of ten seconds) on a brake dyna-
mometer. Turn the key in the ignition lock
to position 0or 1. You could otherwise
damage the drive train or the brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system.

trailer stabilisation 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 can
detect when the trailer begins to lurch.
ESP ®
slows the vehicle down by braking and
limiting the engine output until the vehicle/
trailer combination has stabilised.
Trailer stabilisation is active above speeds of
about 65 km/h. G
Risk of accident
If road and weather conditions are poor,
trailer stabilisation will not be able to prevent Driving safety systems
