Methodofoperation
During the first stag eofacollision, the restraint
system control uni tevaluates important physi-
cal data relating to vehicle deceleratio noraccel-
eration, such as:
RDuration
RDirection
RIntensity Base
dont he evaluatio nofthis data, the
restraint system control uni ttriggers the Emer-
gency Tensioning Device sinthe event of afron-
tal or rear-end collision.
An Emergency Tensioning Device can only be
triggered if:
Rthe ignition is switched on
Rthe components of the restraint system are
operational .You can find furthe rinformation

If the restraint system control uni tdetects ahigh

restraint system are deployed independently of

tions:
RFront ai rbags
RWindow curtain ai rbag,ift he system deter-
mines that it can offer additional protection to
that provided by the seatb elt
Depending on the person occupying the front-
passenger seat, the front-passenger ai rbag is
activated or deactivated. The front-passenger
front ai rbag can only be deployed in an accident
if the PASSENGER AIR BAG OFF indicator lamp
is off. Observe the informatio nonthe
PASSENGER AIR BAG OFF indicator lamp
(
Ypage 44).
You rvehicle has dual-stage front ai rbags. Dur-
ing the first deployment stage, the front ai rbag
fills with propellant gas which reduces the risk of
injury .The second stag eisthen triggered withi

mi
lliseconds, filling the front ai rbag with the
maximum amount of propellant gas.
The deployment threshold sfor the Emergency
Tensioning Device sand ai rbagsa re calculated
on the basis of the vehicle deceleratio noraccel-
eration occurring at various points in the vehi-
cle. Thisp rocess is pre-emptiv einnature. The
ai rb ag mus tbed eployed on time, at the start of
the collision.
The rate of vehicle deceleratio noracceleration
and the directio nofthe force are essentially

Rcollision angle
Rdeformation characteristics of the vehicle
Rcharacteristics of the object with which the

Factors which can only be seenand measured
afte rthe collision has occurred do not pla ya

do they provide an indication of ai rbag deploy-
ment.
The vehicle may be considerably deformed with-
outana irbagb eing deployed. Thisist he case if
only relativelye asilyd eformable parts have
bee nhit and ahighr ate of deceleration has not
bee nreached .Conversely ,anairbagm ay be
deployed even though the vehicle suffers only
minor deformation. Thisist he case if, for exam-
ple ,very rigid vehicle parts such as the longitu-
dina lbodym embers are hit in an accident and
the rate of deceleration is sufficient.
If the restraint system control uni tdetects aside

evant restraint system components are

Important safety notes
Accident statistics show that childre nsecured

in the front seats. For this reason, Mercedes-
Benz stronglya dvise sthat yo uinstall achild
restraint system on arears eat. Children are
generally better protected there.
If ac hildy ounge rthan twelve years and under

GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularl yonthe metal parts of the child
restraint system. There is arisk of injury.
If you leave the vehicle, taking the child with

system is not exposedtod irect sunlight. Pro-
tect it with ablanket, for example. If the child
restraint system has been exposedtod irect
sunlight, let it cool downb efore securing the
child in it. Never leave children unattended in
the vehicle.
Always make sure that all vehicleo ccupants are
positioned properly in their seats and have cor-
rectly fastened their seat belts. Take particular
care with children.
Please take note of the safety notes on seat

LATCH-type (ISOFIX) chil dseat secur-
ing system
GWARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg )who are secure dusing the safety belt
integrated in the child restraint system. In the
event of an accident, achild might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is als osecured
with the vehicl eseat belt. Also secure the
child restraint system with the Top Tether
belt, if available.
Make sure you observe the manufacturer's
installation and operating instructions of the
child restraint system used.
Before each journey ,make sure that the LATCH-
type (ISOFIX) child restraint system is properly
engage dinboth LATCH-type (ISOFIX) securing

!When fitting the child restraint system in
vehicles with arear bench seat, make sure
that the seat belt for the center seat does not
get trapped. Otherwise, the seat belt could be
damaged.
