Belt tensioners, belt force limiters The seat belts are fitted with belt tensioners.
The belt tensionerst ighten the seat belts in
an accident, pulling them close against the
body.
Belt tensionersdon ot correct incorrects eat
positions or incorrectly fastened seat belts.
Belt tensionersdon ot 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. These
take on apart of the deceleration force. Thus,
the force exerted on the occupant is distrib-
uted over agreater area.
The belt tensionersc an only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 39).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in the
front.
The belt tensionersont he 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 Cabriolet: in certain situation sifthe vehicle
overturns and 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. G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at aqualified specialist work-
shop.
Comply with safety regulations when dispos-
ing of belt tensioners .Any Mercedes-Benz
Service Centr ecan 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. 50

Important safety notes G
WARNING
To reduc ethe riskofs erious or even fatal
injury to the child in the event of asudden
change in direction, braking or an accident:
R children less than 1.50mt all 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 secure children less than 1.50mt all
or unde rtwelve years of age on th efront-
passenger seat .Exception: the vehicl eis
equipped with automatic child sea trecog-
nition on the front-passenger seat and the
child is secured in achild restraint system
with transponders for automatic child seat
recognition.
R if you secure aforward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R children must never travel sitting on the lap
of another occupant .Due to the forces
which occur in the event of asudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to as uitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fitting achild restraint
system, observe the manufacturer's installa- tion instructions and the correct use of the
child restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must alway
srest on the seat cushion. There-
fore, never place objects, e.g. acushion,
under the child restraint system.
Only use child restraint systems with the orig-
inal cover designed for them. Only replace
damaged cover swith genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Benz vehicles.
If ac hild is travellin ginyour vehicle, secure
the child using achild restraint system which
is appropriate to the size, age and weight of
the child and recommended for Mercedes-
Benz vehicles. You should preferably fit the
restraint system to asuitable rear seat. Make
sure that the child is secured in achild
restraint system throughout the trip.
Mercedes-Benz recommends that you only
use the child restraint systems listed at
(Y page 59).
You can obtain further information about the
correct child restraint system from any
Mercedes-Benz Service Centre.
i It is advisable to use Mercedes-Benz care
product stoclean child restraint systems.
You can obtain information about this at
any Mercedes-Benz Service Centre. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in achild
restraint system. They could injure them-
selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys- Children in the vehicle
