Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 28).Occupant safety
Important safety notes
Seat belts, together with the Supplemental
Restraint System – SRS (Y page 47), are
complementary, co-ordinated restrain tsys-
tems .They reduce the risk of injury in spe-
cific, pre-defined types of accident situations
and thereby increase occupant safety. How-
ever, seat belts and airbags generally do not
protect against objects penetrating the vehi-
cle 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 104).
R the seat belt has been fastened properly
(Y page 55).
R the airbags can inflate unrestricted if
deployed (Y page 48).
R the steering wheel is adjusted properly
(Y page 104).
R the restraint systems have not been modi-
fied.
i An airbag increases the protection of
vehicle occupants wearing a seat belt. As
such, they are only an additional restraint
system which complements, but does not
replace, the seat belt. All vehicle occupants must wear their seat belt correctly at all
times, even if the vehicle is equipped with
airbags. The airbags are not deployed in all
types of accidents. For example, if the pro-
tective capacity of correctly fastened seat
belts is not increased by deploying the air-
bags, the airbags will not deploy.A
irbag
deploymen tonly provides increased pro-
tection if the seat belt is worn correctly
because:
R the sea tbelt helps to keep the vehicle
occupan tinthe best position in relation
to the airbag.
R in a head-on collision, for example, the
seat belt prevents the vehicle occupant
from being propelled towards the point
of impact. It can thus reduce the risk of
injury.
In accidents in which an airbag is deployed,
it provides increased protection only if the
seat belt is worn correctly. G
WARNING
If service work is not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety systems may no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. The workshop
must have the necessary specialist knowl-
edge and tools to carry out the work required.
Mercedes-Ben zrecommends 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. 46
Occupant safetySafety

G
WARNING
Modifications to or work performed incor-
rectly on the following parts can result in the
restraint systems not functioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, beltt en-
sioners, belt force limiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an acciden tdespite
the deceleration force being sufficien tto trig-
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. SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
the 6 SRS warning lamp
R airbags
R airbag control unit (with crash sensors)
R belt tensioners
R belt force limiters
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS warning lamp SRS functions are 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 a few seconds
after the engine is started. G
WARNING
If SRS is malfunctioning, individual systems
may be activated unintentionally or may not
be triggered in the event of an accident with
a high rate of vehicle deceleration.
A malfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignition is switched on.
R the engine is running and the 6SRS
warning lamp does not go out after a few
seconds.
R the engine is running and the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at a qualified specialist workshop. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose.
In particular, work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of a collision, 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.
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.
If there is an even higher rate of vehicle decel-
eration or acceleration in a longitudinal direc-
tion, the front airbags are also deployed.
Your vehicle has adaptive, two-stage front air-
bags. The airbag control unit evaluates vehi-
cle deceleration or acceleration in the event Occupant safety
47Safety Z

of a collision. In the first deployment stage,
the front airbag is filled with enough propel-
lant gas to reduce the risk of injuries. The
front airbag is fully deployed if a second
deployment threshold is exceeded within a
few 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.
i Airbags are not deployed in all types of
accidents. Also, not all airbags are
deployed together in an accident .The dif-
ferent airbag systems work independently
of each other.
How the airbag system works is deter-
mined by the severity of the collision detec-
ted, especially the vehicle deceleration or
acceleration, and the apparent type of acci-
dent:
R head-on collision
R side impact
R rear impact
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 a collision 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 a result.
Airbags
Important safety notes Airbag deployment slows down and restricts
the movement of the vehicle occupant.
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
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The
6SRS warning lamp
lights up.
The airbag installation locations are identified
by the AIRBAG symbol. G
WARNING
Airbags provide additional protection; they
are not, however, a substitute 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-
nant women – must wear their seat belt
correctly at all times and lean back against
the backrest, which should be positioned
as close to the vertical as possible. The
head restraint must support the back of the
head at about eye level.
R always secure childre nless than 1.50mt all
and unde r12years of age in suitable child
restraint systems.
R all vehicle occupants must select a seat
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 48
Occupant safetySafety

G
WARNING
The airbag parts are hot after the airbag has
been deployed. Do not touch them as you
could burn yourself.
Have the airbags replaced at a qualified spe-
cialist workshop. Otherwise, occupants are
not protected by the airbags in the event of
another accident.
Fron tairbags The fron
tairbags increase protection for the
driver's and front-passenger's head and
chest. Driver's airbag
:deploys in front of the
steering wheel; front-passenger airbag ;
deploys in front of and above the glove com-
partment.
They are deployed:
R at the start of an accident with a high rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deploymen tcan offer additional protection
to that provided by the seat belt
R if the seat belt is fastened
R independently of other airbag sinthe vehi-
cle
Front-passenger airbag ;is only activated if
the system determines that the front-
passenger seat is occupied. The 4
PASSENGER AIRBAG OFF indicator lamp on
the centre console is not lit (Y page 59).
This means that a child restraint system with- out automatic child seat recognition has been
fitted or that a child restraint system with
automatic child seat recognition is incorrectly
fitted.
!
Do not place heavy objects on the front-
passenger seat. The system may then
detect that the seat is occupied and if there
is an accident, the restraint systems on the
front-passenger side could be deployed.
Have restraint systems that have been trig-
gered replaced.
Driver's kneebag i
The driver's kneebag is only available in
certain countries.
The driver's kneebag increases protection of
the driver against:
R knee injuries
R thigh injuries
R lower leg injuries Driver's kneebag
:is always deployed along
with the driver's airbag and inflates under-
neath the steering column.
Sidebags G
WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Ben zvehicles.
The seat covers must have a special tear seam
for sidebags. Otherwise, the sidebags cannot
deploy correctly and would fail to provide the 50
