Occupant safety
36 Occupant safety
Notes on occupant safety
Seat belts, together with belt tensioners, belt
force limiters and airbags, are coordinated
restraint systems. They reduce the risk of
injury in defined 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, you
should ensure that:
R the seat and head restraint are adjusted
properly (Y page 63)
R the seat belt has been fastened properly
(Y page 72)
R the airbags can inflate properly if they are
deployed (Y page 39)
R the steering wheel is adjusted properly
(Y page 69)
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 force 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
purpose.
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 oper-
ating safety of your vehicle may be affec-
ted. 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
deceleration force would normally be high
enough to trigger the systems, or they
could be triggered unintentionally. Never Safety

Occupant safety
38airbag deployment must take place during
the impact and must be adapted to provide
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. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal 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 rear are equipped with belt tensioners.
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 the
forces exerted by the belt force limiters on
the occupant over a greater area.
When the ignition is switched on, the belt ten-
sioner is triggered:
R
only if the restraint systems are operational
(the 1 warning lamp lights up after the
ignition is switched on and goes out once
the engine is running) (Y page 37)
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
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 escapes
does not generally constitute a health hazard.
The 1 warning lamp lights up. G
Risk of injury
If the seat belt tensioners have been trig-
gered, they provide no additional protec-
tion in the event of another accident. There-
fore, have belt tensioners which have been
triggered replaced at a qualified specialist
workshop. Safety

Driving safety sys
tems56 G
Risk of accident
If BAS has malfunctioned, the braking sys-
tem remains available with full brake boost-
ing effect. However, braking force is not
automatically increased in emergency
braking situations and the stopping dis-
tance 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 50 km/h or 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 ( Ypage 79). ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
ESP ®
detects when a wheel spins or the vehi-
cle starts to skid. ESP ®
stabilises the vehicle
by targeted braking of individual wheels and
by limiting engine power. It assists you when
pulling away on wet or slippery roads. ESP ®
also stabilises the vehicle during braking.
When ESP ®
intervenes, the vwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the v warning lamp in the instrument
cluster flashes, proceed as follows:
R only depress the accelerator pedal as far
as necessary when pulling away.
R adapt your driving style to suit the pre-
vailing road and weather conditions.
The vehicle could otherwise go into a skid.
ESP ®
cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot override
the laws of physics.
! The ignition must be switched off (key in
position 0or 1in the ignition lock), if: R
the parking brake is being tested using a
dynamometer
R the vehicle is being towed with the front
axle raised
Application of the brakes by ESP ®
could
otherwise destroy the brake system on the
front axle.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly. Steering assistant STEER CONTROL
The steering assistant STEER CONTROL helps
you by transmitting a noticeable steering
force to the steering wheel in the direction
required for vehicle stabilisation. This steer-
ing assistance is provided in particular if:
R both right wheels or both left wheels are on
a wet or slippery road surface when you
brake
R the vehicle starts to skid
You have control over the steering at all
times. G
Risk of accident
If there is an ESP ®
malfunction, you will not
receive any steering assistance from the Safety

passenger
The < seat belt warning lamp in the instru-
ment cluster reminds you that all passengers
should fasten their seat belts. It may light up
continuously or flash. Additionally, there may
be a warning tone.
The < seat belt warning lamp goes out and
the acoustic signal ceases as soon as the
driver and passenger have fastened their seat
belts.
For certain countries only: regardless of
whether the driver or the front passenger
already have their seat belt fastened, the
< seat belt warning lamp lights up for six seconds after the engine has been started. It
then goes out when the driver and front
passenger have already fastened their seat
belts.
