Correct use
Observe the following information when using
your vehicle:
R the safety notes in this manual
R the "Technical data" section in this manual
R national road traffic regulations
R national road traffic licensing regulations G
Risk of injury
Various warning stickers are affixed to your
vehicle. Their purpose is to draw your atten-
tion, and the attention of others, to various
dangers. Therefore, do not remove any warn-
ing stickers unless the sticker clearly states
that you may do so.
If you remove the warning stickers, you or
others could be injured by failing to recognise
certain dangers. Data stored in the vehicle
Fault data
Components critical for vehicle operation are
equipped with fault data memories as stand-
ard. There are also memories dedicated to
storing the technical reactions of vehicle
components to driving situations (e.g. the
triggering of an airbag, ESP ®
intervention).
This data is used exclusively to:
R assist in the rectification of faults and
defects
R help Mercedes-Benz optimise and develop
vehicle functions.
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced by Mercedes-
Benz, this technical information can be read
from the fault memories. This is performed by
authorised employees of the Mercedes-Benz
service network using special diagnostic
computers. After a fault has been rectified, the informa-
tion is deleted from the memory. Other mem-
ory data is constantly overwritten. Other devices that store data
Depending on its equipment, your vehicle
may feature communications and/or enter-
tainment systems (e.g. navigation devices,
telephone systems). These allow you to save
and edit data required for the operation of the
respective device.
Further information on operation (e.g. on
deleting data) can be found in the separate
operating instructions. Introduction

Occupant safety
Notes on occupant safety
Seat belts, together with belt tensioners, belt
force limiters and airbags, are complemen-
tary, coordinated restraint systems. They
reduce the risk of injury in specific, pre-
defined types of accident situations and
thereby increase occupant safety. However,
seat belts and airbags generally do not pro-
tect against objects penetrating the vehicle
from the outside.
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 64).
R the seat belt has been fastened properly
(Y page 75).
R the airbags can inflate properly if they are
deployed (Y page 37).
R the steering wheel is adjusted properly
(Y page 70).
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupants wearing a seat belt.
However, airbags are only an additional
restraint system which complements, but
does not replace, the seat belt. All vehicle
occupants must wear their seat belt cor-
rectly at all times, even if the vehicle is
equipped with airbags. This is because – on
the one hand – airbags are not deployed in
all types of accident, as in some situations
airbag deployment would not increase the
protection afforded to vehicle occupants,
provided they are wearing their seat belt
correctly. On the other hand, airbag deploy-
ment only provides increased protection if
the seat belt is worn correctly because: R
the seat belt helps to keep the vehicle
occupant in the best position in relation
to the airbag.
R for example, in a head-on collision, the
seat belt can more adequately prevent
the occupant from being propelled
towards the point of the impact, and is
thus better suited to prevent injury.
Therefore, in accident situations where an
airbag is deployed, it only provides protec-
tion in addition to the seat belt if the seat
belt is being worn correctly. G
Risk of accident and injury
Always have maintenance work carried out at
a qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose.
In 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 operating safety
of your vehicle may be affected. There is a risk
of an accident and injury. G
Risk of injury
The restraint system may not work as inten-
ded if the following components have been
modified or work on these components has
not been performed correctly:
R restraint system, consisting of the seat
belts and anchorages, belt tensioners, belt
force limiters, airbags
R wiring
R networked electronic systems
Airbags or belt tensioners could then fail, e.g.
in the event of an accident in which the decel-
eration force would normally be high enough
to trigger the systems, or they could be trig-
gered unintentionally. Never carry out any
modifications on the restraint systems. 34

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
