Fault data
Components which are critical for vehicle
operation are equipped with fault data mem-
ories as standard. There are also data storage
devices which recor dhow vehicle compo-
nents have reacted in certain driving situa-

R assist in the rectification of faults and
defects
R help Mercedes-Benz optimise and develop
vehicle functions
The data cannot be used to trac ethe vehicle's
movements.
When your vehicle is serviced by Mercedes-
Benz ,this technical information can be read
out from the fault memory. This is performed
by authorised employees of the Mercedes-
Benz service network using special diagnos-
tic computers.
After afault has been rectified, the informa-
tion is deleted from the memory. Other mem-

WARNING
If servic ework is not carried out correctly, the
operatin gsafet yofy our vehicle may be affec-
ted. This could cause you to lose contro lof
your vehicle and cause an accident. More-
over, the safet ysystem smay no longer be
able to protect you or other sastheya re

Always have servic ework carried out at a
qualified specialist workshop. G
WARNING
Modification stoorwork performed incor-
rectly on th efollowin gpartsc an result in the
restraint systems no tfunctionin gasintended:
R ther estraint system, consisting of seat
belt sand their anchorage points ,belt ten-
sioners ,belt force limiters and airbags
R thew iring
R networked electronic systems
Airbags and belt tensioners could fail to
deplo yorbet riggered in an acciden tdespite
the deceleration forc ebeing sufficien ttotrig-
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.
The seat belts, together with SRS (Supple-
mental Restraint System), are complemen-
tary, co-ordinated restraint systems
(Y page 41). They reduce the risk of injury
in specific, pre-defined types of accident sit-
uations and thereby increase occupant
safety. However, seat belts and airbags gen-
erally do not protect against object spene-
tratin gthe vehicle from the outside. 40
Occupant safetySafety

To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R
the seat and head restraint are adjusted
properly (Y page 96).
R the seat belt has been fastened properly
(Y page 48).
R the airbags can inflate unrestricted if
deployed (Y page 42).
R the steerin gwheel is adjusted properly
(Y page 102).
R the restraint systems have not been modi-
fied.
An airbag increases the protection of vehicle
occupant swearing aseat belt. However, air-
bags are only an additional restraint system
which complements, but does not replace,
the seat belt. All vehicle occupant smust wear
their seat belt correctly at all times, even if
the vehicle is equipped with airbags. The air-
bags are not deployed in all types of acci-
dents .For example, if the protective capacity
of correctly fastened seat belts is not
increased by deploying the airbags, the air-
bags will not deploy.
Airbag deployment only provides increased
protection if the seat belt is worn correctly.
First,t he seat belt helps to keep the vehicle
occupant in the best position in relation to the
airbag. Second, in ahead-on collision, for
example, the seat belt prevent sthe vehicle
occupant from being propelled towards the
point of impact. SRS (Supplemental Restraint System)
Introduction SRS consist
sof:
R the 6 SRS warning lamp
R airbags
R the airbag control unit with crash sensors
R belt tensioners
R belt force limiters SRS reduces the risk of occupant
scoming
into contact with the vehicle's interior in the
event of an accident .Itcan also reduce the
forces to which occupant sare subjected dur-
ing an accident.
SRS warnin glamp G
WARNING
If SRS is malfunctioning, individuals ystems
may be triggere dunintentionally or might not
be triggere dinthe event of an accident with
ah igh rate of vehicl edeceleration.
Am alfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignitio nisswitched on.
R the engine is running and the 6SRS
warning lamp does not go out after afew
seconds.
R the engine is running and the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at aq ualified specialist workshop.
SRS functionsa re 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 afew seconds
after the engine is started.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of
acollision, 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. Occupant safety
41Safety Z

If there is an even higherr
ate of vehicle decel-
eration or acceleratio ninalongitudinal direc-
tion ,the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluate svehi-
cle deceleration or acceleration in the event
of ac ollision. In the firs tdeployment stage,
the fron tairbag is filled with enough propel-
lant gas to reduc ethe risk of injuries. The
front airbag is fully deployed if asecond
deploymen tthreshold is reached within afew
milliseconds.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration or acceleration of the
vehicle. This process is pre-emptive in nature.
The triggering process must take place in
good time at the start of the collision.
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 has collided
Factors which can only be seen and measured
after acollision has occurred do not play a
decisive role in the deployment of an airbag,
nor do they provide an indication of airbag
deployment.
The vehicle may be deformed significantly,
e.g. the bonnet or the wing, without an airbag
being deployed. This is the case if only parts
which are relatively easily deformed are affec-
ted and the rate of deceleration is not high.
Conversely, airbags may be deployed even
though the vehicle suffers only minor defor-
mation. This is the case if, for example, very
rigid vehicle parts such as longitudinal body
members are hit, and sufficient deceleration
occurs as aresult. 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.
i Not all airbags are deployed in an acci-
dent. The different airbag systems work
independently of each other.
How the airbag system works is deter-
mined by the severity of the accident detec-
ted, especiallyt he vehicle deceleration or
acceleration, and the apparent type of acci-
dent:
R head-on collision
R side impact
R overturn Airbags
Important safety notes G
WARNING
Airbags provide additional protection; they
are not, however, asubstitute for seat belts.
Observe the following notes to reduce the risk
of serious or even fatal injury caused by airbag
deployment:
R all vehicle occupants –inparticular ,preg-
nan twome n–m ust wear their seat belt
correctly at all times and lean back against
th eb ackrest, whic hshoul dbep ositioned
as close to th evertical as possible. The
head restraint must support th eback of the
head at about eye level.
R always secure childre nless than
1.50mt all or unde r12years of age in suit-
able child restraint systems.
R all vehicle occupant smust select aseat
position that is as far away from the airbag
as possible. The driver's seat position must
allow the vehicle to be driven safely. The
driver's chest should be as far away from
the centre of the driver's airbag cover as
possible. 42
