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

Have the airbags replaced at
aqualifie dspe-
cialist workshop .Otherwise, occupants are
not protecte dbythe airbags in the event of
anothe raccident.
Airba gdeployme nt slowsdowna nd restricts
the movement of the vehicl eoccupant.
If the airbags ar edeployed, you will hear a
bang ,and asmall 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 AIRBAGs ymbol.
Front airbags !
Do not place heavy object sonthe 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'
sairbag :deploys in front of the
steerin gwheel; front-passenger front air-
bag ;deploys in front of and above the glove
compartment.
The front airbags increase protection for the
driver's and front-passenger's head and
chest. They are deployed:
R
at the start of an accident with ahigh rate
of vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that airbag
deployment can offer additional protection
to that provided by the seat belt
R depending on whether the seat belt is being
used
R independently of other airbags in the vehi-
cle
If the vehicle overturns, the front airbags are
generally not deployed. The front airbags are
deployed if the system detect shigh vehicle
deceleration in alongitudinal direction.
Vehicles with automatic child seat recog-
nition in the front-passenger seat: front-
passenger airbag is only activated if the sys-
tem determines that the front-passenger seat
is occupied. The 4PASSENGER AIRBAG
OFF indicator lamp on the centre console
does not light up (Y page 54).
If ac hild restraint system is fitted to the front-
passenger seat and the 4PASSENGER
AIRBAGO FF indicator lamp does not light up
on the centre console:
R ac hild restraint system without transpond-
ers for automatic child seat recognition is
fitted or
R ac hild restraint system with transponders
is not properly fitted.

Comply wit
hsafety regulation swhen dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The seat belts are fitted with belt tensioners.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrects eat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with abelt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the front seats are
synchronised with the front airbags, which
take on apart of the deceleration force. This
results in the force exerted on the occupant
being distributed over agreater area.
The belt tensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 41).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in front.
R
The belt tensioners on the seats in the rear
compartmenta re triggeredindependently of
the lock status of the seat belts.
The beltt ensioners are triggered depending
on the type and severit yofanaccident:
R if, in the event of ahead-on or rear-en dcol-
lision the vehicle decelerates or acceler- ates rapidly in
alongitudinal direction dur-
ing the initial stages of the impact
R if, in the event of aside impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in alateral direc-
tion
R in certain situation swhere the vehicle over-
turn sand the system determines that it can
provide additional protection
If the airbags are deployed, you will hear a
bang, and asmall 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. Children in the vehicle

WARNING
To reduce the risk of serious or even fatal
injur ytot he child in the event of asudden
change in direction, brakin goranaccident:
R children less than 1.5 0mtall and under
twelve years of age must alway sbesecured
in special child restraint systems on asuit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R Do not drive with achild secured in arear-
ward-facin gchild restraint system on the
front-passenger seat. Exception: if the vehi-
cle is equipped with automatic child seat
recognition on the front-passenger seat
and the child is secured in achild restraint
system with transponder sfor automatic
child seat recognition
R if you secure aforward-facing child
restraint system to the front-passenger 52
Children in thev
ehicleSafety

R
only use aforward-facin gchild restraint
system on the front-passenger seat and
move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at aqualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. acushion, 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 cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries. G
WARNING
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
Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up without there being achild
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
It is also possible that the 6SRS warning
lamp lights up and/or the 4PASSENGER
AIRBAG OFF indicator lamp does not light up
briefly when you turn the key in the ignition
lock to position 2. If your vehicle does not have automatic child
seat recognition on the front-passenger seat,
this is indicated by
aspecial sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
Vehicles without automatic child seat recog-
nition on the front-passenger seat: when you
turn the key to position 2inthe ignition lock,
the 4 PASSENGER AIRBAG OFF indicator
lamp lights up briefly, but does not have any
function. It does not indicate that there is
automatic child seat recognition on the front-
passenger seat. The front-passenger seat sensor system for
child restraint systems detectsw
hether a
special Mercedes-Ben zchild seat with a
transponder for automatic child seat recog-
nition has been fitted. In this case, 4
PASSENGER AIRBAG OFF indicator lamp :
lights up. The front-passenger front airbag is

If you brake sharply from aspeed of more
than 50 km/h or if braking is assisted by BAS
or BAS PLUS, the brake lamps flash rapidly.
In this way,t raffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from aspeed of more
than 70 km/h to astandstill, the hazard warn-
ing lamps are activated automatically .Ifthe
brakes are applied again, the brake lamps
light up continuously.T he 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

Observe the "Important safety notes" sec-
tion (Y page 62). G
WARNING
If ESP ®
is malfunctioning, ESP ®
is unable to
stabilise the vehicle. In addition, other driving
safety systems are switched off. This increa-
ses the risk of skidding and an accident.
Drive on carefully. Have ESP ®
checked at a
qualified specialist workshop.
! Vehicles with 4MATIC: switch off the igni-
tion when the parking brake is being tested
using adynamometer.
Application of the brakes by ESP ®
may oth-
erwise destroy the brake system.
Vehicles without 4MATIC: observe the notes
on ESP ®
if the vehicle is being towed with the
rear axle raised (Y page 322).
ESP ®
is deactivated if the åwarning lamp
in the instrument cluster lights up continu-
ously when the engine is running.
If the ÷ warning lamp and the åwarn-
ing lamp are lit continuously, ESP ®
is not
available due to amalfunction.
Observe the information on warning lamps
(Y page 263) and display messages which
may be shown in the instrument cluster
(Y page 232).
If ESP ®
detect sthat the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. 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 slippery roads. ESP ®
can also stabilise the vehicle during braking.
If ESP ®
intervenes, the ÷ESP®
warning
lamp flashes in the instrument cluster. Driving safety systems
