Introduction to the restraint system
The restraint system can reduce the risk of vehi-
cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident. Furthermore, the restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system The various components of the restraint system
work complementary to one another. They can
only perform their intended protective function
if all vehicle occupants:
R have correctly fastened their seat belt
(Y page 45)
R have correctly adjusted their seat and head
restraint (Y page 102).
As the driver, you must also ensure that the
steering wheel is correctly adjusted. Observe
the information relating to the correct driver's
seat position (Y page 102).
Additionally, you must ensure that an airbag can
deploy freely (Y page 47).
The airbag is supplementary to a correctly fas-
tened seat belt. As an additional safety device,
the airbag increases the level of protection for
vehicle occupants in the event of an accident. If the protection provided by the seat belt is suf-
ficient, the airbags do not deploy. Furthermore,
in the event of an accident, only airbags which
provide greater protection in the given accident situation deploy. However, seat belts and air-
bags generally do not protect against objects
penetrating the vehicle from the outside.
Information on how the restraint system oper-
ates can be found in "Deployment of the seat
belt tensioner and airbags" (Y page 54).
See "Children in the vehicle" for information on
infants and children traveling with you in the
vehicle restraint systems for infants and chil-
dren(Y page 57). Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If the vehicle needs to be adapted to accommo- date a person with disabilities, please contact a
specialist workshop. 42
Occupant safetySafety

Mercedes-Benz recommends that you use only
driving aids that have been approved specifi-
cally for your vehicle by Mercedes-Benz. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at regular intervals while the engine is running.
Therefore, malfunctions can be detected in
good time.
The 6 restraint system warning lamp on the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec- onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 6restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not go out after a few seconds with the
engine running
R lights up again while the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This may affect
the seat belt tensioner or airbag, for example. This poses an increased risk of injury or even
fatal injury.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop. PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp
:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the automatic deactivation system of the front-passenger front airbag.
The indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is off, only the PASSENGER AIR BAG OFF indicator
lamp shows the status of the front-passenger
front airbag. The PASSENGER AIR BAG OFF indi-
cator lamp may be lit continuously or be off.
Depending on the person in the front-passenger seat, the front-passenger front airbag must be
either disabled or enabled; see the following
points. You must make sure of this both before
and during a journey.
R Children in a rearward-facing child
restraint system: the PASSENGER AIR BAG
OFF indicator lamp must be lit. The front-
passenger front airbag is disabled. It is imper-
ative to observe the notes on the "Automatic front-passenger front airbag deactivation sys-
tem" (Y page 50) and on "Children in the
vehicle" (Y page 57).
R Children in a forward-facing child
restraint system: depending on the installed
child restraint system and the age and size of the child, the front-passenger front airbag is
either disabled or enabled. Therefore, it is
imperative to observe the notes on the "Auto-
matic front-passenger front airbag deactiva- Occupant safety

event of an accident, they could be crushed
between the vehicle occupant and seat belt.
R Do not secure any objects with a seat belt if
the seat belt is being used by one of the vehi- cle's occupants.
You must also make sure that objects, e.g.
cushions, are never placed between a person
and the seat.
Seat belts are solely intended to secure and
restrain persons. To secure objects, luggage or
loads, always observe the "Loading guidelines"
(Y page 312).
Fastening and adjusting the seat belts Observe the safety notes on the seat belt
(Y
page 44) and the information on the correct
use of the seat belt (Y page 45).Basic illustration
X Adjust the seat (Y page 102).
The seat backrest must be in an almost ver-
tical position.
X Pull the seat belt smoothly from the belt outlet
and engage belt tongue ;into belt
buckle :.
The seat belt on the driver's seat and the
front-passenger seat may be tightened auto-
matically; see "Belt adjustment"
(Y page 46).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body. The shoulder section of the seat belt must
always be routed across the centre of the shoul-
der. Adjust the belt outlet if necessary.
X To raise: slide the belt outlet upwards.
The belt outlet will engage in various posi-
tions.
X To lower: hold belt outlet release =and slide
belt outlet downwards.
X Let go of belt outlet release =in the desired
position and make sure that the belt outlet
engages.
Releasing seat belts !
Make sure that the seat belt is fully rolled up.
Otherwise, the seat belt or belt tongue will be
trapped in the door or in the seat mechanism. This could damage the door, the door trim
panel and the seat belt. Damaged seat belts
can no longer fulfil their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
X Press release button in belt buckle, hold belt
tongue firmly and guide the seat belt back.
Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE
®
convenience function. This func-
tion adjusts the driver's and front-passenger
seat belt to the upper body of the occupants.
The belt strap is tightened slightly when:
R the seat belt tongue is engaged in the belt
buckle and
R the ignition is switched on
The seat-belt adjustment will apply a certain
tightening force if any slack is detected between
the vehicle occupant and the seat belt. Do not
hold on to the seat belt tightly while it is adjust-
ing.
You can switch the seat-belt adjustment on and
off in the on-board computer (Y page 254).
Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster reminds you that all vehicle occu-
pants must fasten their seat belts. It may light up continuously or flash. A warning tone may also
sound. 46
Occupant safetySafety

If the system determines that it can offer addi-
tional protection to that provided by the seat
belt, a windowbag may be deployed in other
accident situations (Y page 54).Automatic front-passenger front air-
bag deactivation
Introduction In order to recognise a child restraint system on
the front-passenger seat, the automatic front-
passenger front airbag deactivation system cat- egorises the person in the front-passenger seat.Depending on that result, the front-passenger
front airbag is either enabled or disabled. If a
rearward-facing child restraint system is fitted
to the front-passenger seat, the PASSENGER
AIR BAG OFF indicator lamp must light up after
the system self-test and remain lit. The front-
passenger front airbag is disabled.
The system does not disable:
R the sidebag
R the windowbag
R the seat belt tensioner
In the following situation, the sidebag and the
seat belt tensioner are deactivated:
R the automatic front-passenger front airbag
deactivation system has not categorised the
person in the front-passenger seat as an adult or a person of corresponding stature and
R the seat belt tongue of the seat belt is not
inserted into the front-passenger seat belt
buckle
Make sure that your vehicle is equipped with the
automatic front-passenger front airbag deacti-
vation system (Y page 61). If this is not the
case, always install a child restraint system on a
suitable rear seat (Y page 62).
If it is absolutely necessary to install a child
restraint system on the front-passenger seat, be
sure to observe the correct positioning of the
child restraint system. Never place objects
under or behind the child restraint system, e.g. a
cushion. The entire base of the child restraint
system must always rest on the seat cushion of the front-passenger seat. The backrest of the
forward-facing child restraint system must, as
far as possible, be resting on the backrest of the
front-passenger seat. The child restraint system
must not touch the roof or be put under strain by the head restraint. Adjust the angle of the seat backrest and the head restraint position accord-
ingly. Only then is the correct function of the
automatic front-passenger front airbag deacti-
vation system guaranteed. Always observe the
information on suitable positioning of the child
restraint system (Y page 62) in addition to the
child restraint system manufacturer's installa-
tion instructions.
Operation of automatic front-passenger
front airbag deactivation :
PASSENGER AIR BAG ON indicator lamp
; PASSENGER AIR BAG OFF indicator lamp
The indicator lamps inform you whether the
front-passenger front airbag is disabled or ena-
bled.
X Press the Start/Stop button once or twice, or
turn the key to position 1or 2in the ignition
lock.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF and PASSENGER
AIR BAG ON indicator lamps must light up simul- taneously for approximately six seconds.
The indicator lamps display the status of the
front-passenger front airbag:
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, then both indicator lamps are off
(PASSENGER AIR BAG ON and OFF): the front-
passenger front airbag is able to deploy in the
event of an accident.
R PASSENGER AIR BAG OFF lights up: the front-
passenger front airbag is disabled. It will then
not be deployed in the event of an accident.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front airbag. The PASSENGER AIR BAG OFF indi-
cator lamp may be lit continuously or be off. 50
