Deployment of belt tensioners and air-
bags
Important safety notes G
WARNING
After the airbag deploys, the airbag parts are
hot. There is a risk of injury.
Do not touch the airbag parts. Have a
deployed airbag replaced at a qualified spe-
cialist workshop as soon as possible. G
WARNING
Pyrotechnic seat belt tensioners that have
been deployed are no longer operational and
are unable to perform their intended protec-
tive function. This poses an increased risk of
injury or even fatal injury.
Therefore, have pyrotechnic belt tensioners
which have been triggered immediately
replaced at a qualified specialist workshop.
Mercedes-Benz recommends that you have
the vehicle towed to a qualified specialist
workshop after an accident. Take this into
account, particularly if a seat belt tensioner
was triggered or an airbag was deployed.
An electric motor is used by PRE-SAFE ®
to
trigger the tightening of the seat belt in haz-
ardous situations. This procedure is reversi-
ble.
If the belt tensioners are triggered or an air-
bag is deployed, you will hear a bang, and a
small amount of powder may also be
released. The 6restraint system warning
lamp lights up.
Only in rare cases will the bang affect your
hearing. In general, the powder released is
not hazardous to health but may cause short- term breathing difficulties to persons suffer-
ing from asthma or other pulmonary condi-
tions. Provided it is safe to do so, you should
leave the vehicle immediately or open the
window in order to prevent breathing difficul- ties. Operation During the first stage of a collision, the
restraint system control unit evaluates impor-
tant physical data relating to vehicle deceler-
ation or acceleration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the seat
belt tensioners in the event of a head-on or
rear collision.
A seat belt tensioner can only be triggered if:
R the ignition is switched on.
R the components of the restraint system are
operational; see "Restraint system warning
lamp" (Y page 43)
R the belt tongue has engaged in the belt
buckle of the respective front seat
The seat belt tensioners in the rear compart-
ment are triggered independently of the lock
status of the seat belts.
If the restraint system control unit detects a
high severity of an accident, in certain head-
on collisions, additional components of the
restraint system are deployed independently
of each another:
R front airbags and driver's kneebag
R windowbag, if the system determines that
deployment can offer additional protection to that provided by the seat belt
On vehicles with the automatic front-
passenger front airbag deactivation system:
depending on the person in the front-
passenger seat, the front-passenger front air-
bag is either disabled or enabled. The front-
passenger front airbag can only be deployed
in an accident if the PASSENGER AIR BAG ON indicator lamp is lit. Observe the information
on the PASSENGER AIR BAG indicator lamps
(Y page 43).
Your vehicle has two-stage front airbags. In
the first deployment stage, the front airbag is
filled with propellant gas to reduce the risk of Occupant safety
57Safety Z
Page 61 of 401
injuries. The front airbag is fully deployed if
the second deployment stage is activated
within a few milliseconds.
The activation threshold for the seat belt ten-
sioners and airbags is determined based on
the evaluation of the vehicle's rate of decel-
eration or acceleration at various points in the vehicle. This process is pre-emptive in nature.The triggering/deployment process should
take place in good time at the start of the
collision.
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen-
tially 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
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 airbag
deployment.
The vehicle may be deformed significantly
without an airbag being deployed. This is the
case if only parts which are relatively easily
deformed are affected and the rate of decel-
eration is not high. Conversely, an airbag may be deployed even though the vehicle suffers
only minor deformation. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are hit, and sufficient deceleration occurs as a result. If the restraint system control unit detects a
side impact or if the vehicle overturns, the
applicable components of the restraint sys-
tem are activated independently of each
other depending on the apparent type of acci-
dent. If the system determines that, in this
situation, triggering can offer additional pro-
tection, the seat belt tensioners are also trig-
gered.
R Sidebags on the side on which an impact
occurs, independent from the seat belt ten-
sioner and seat belt usage
Vehicles with the automatic front-
passenger front airbag deactivation sys-
tem: the sidebag on the front-passenger
side (front) deploys under the following
conditions:
- an occupant is detected on the front-
passenger seat, or
- the belt tongue is engaged in the buckle
on the front-passenger seat
R Windowbag on the side on which an impact
occurs, independent of seat belt usage and
regardless of whether the front-passenger
seat is occupied
R Windowbags on the driver's and front-
passenger side in certain situations if the
vehicle overturns and if the system deter-
mines that deployment can offer additional protection to that provided by the seat belt
i Not all airbags are deployed in an acci-
dent. The different airbag systems work
independently of each other.
How the airbag system works is deter-
mined by the severity of the accident detec-
ted, especially the vehicle deceleration or
acceleration, and the apparent type of acci- dent:
R frontal collision
R side impact
R overturn 58

R be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions
R be sure to observe the instructions and
safety notes on the automatic front-
passenger front airbag deactivation system (Y page 51). G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position Por shift manual transmission into
neutral
R start the engine
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key with you and lock the vehicle. Never leave
children unattended in the vehicle. G
WARNING
If persons (particularly children) are exposed
to heat or cold for a prolonged period, there is a risk of serious or even fatal injuries. Never
leave persons (particularly children) unatten-
ded in the vehicle. G
WARNING
If the child restraint system is placed in direct sunlight, the parts could become very hot.
Children could be suffer burns by touching
these parts, in particular on the metallic parts
of the child restraint system. There is a risk of injury.
If you and your child leave the vehicle, always
make sure that the child restraint system is
not in direct sunlight. Cover it with a blanket, for example. If the child restraint system has
been exposed to direct sunlight, leave it to cool down before securing the child in it.
Never leave children unattended in the vehi-
cle.
Make sure that all vehicle occupants are
seated properly with a correctly fastened seat belt. This applies particularly to children.
Observe the safety notes on the seat belt
(Y page 44) and the information on the cor-
rect use of the seat belt (Y page 46). Child restraint system
Observe the instructions for correct use of
the child restraint system (Y page 64).
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint sys- tem recommended by Mercedes-Benz
(Y page 68). G
WARNING
If the child restraint system is incorrectly fit-
ted on the seat position suitable for this pur-
pose, it cannot perform its intended protec-
tive function. In the event of an accident,
sharp braking or a sudden change in direction, the child may not be held securely. There is an
increased risk of serious or even fatal injuries.
Observe the manufacturer's installation
instructions and the correct use for the child
restraint system. Make sure that the entire
surface of the child restraint system is resting
on the seat surface. Never place objects
under or behind the child restraint system,
e.g. cushions. Only use child restraint sys-
tems with the original cover designed for
them. Only replace damaged covers with gen- uine covers. G
WARNING
If the child restraint system is fitted incor-
rectly or is not secured, it can come loose in
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system could be thrown about, strik- ing vehicle occupants. There is an increased
risk of injury, possibly even fatal. 60

rect routing of Top Tether belt ?.Child restraint system on the front-
passenger seat
General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat.
Vehicles with the automatic front-passenger
front airbag deactivation system: if it is abso- lutely necessary to fit a child restraint system
to the front-passenger seat, always observe
the information on "Automatic front-
passenger front airbag deactivation system"
(Y page 51).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the automatic front-passenger front air- bag deactivation system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Please observe the warning notice on the
front-passenger sun visor, see the illustra-
tion.
G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to the
CHILD can occur.
If the PASSENGER AIR BAG ON indicator lamp
is lit, the front-passenger front airbag is ena-
bled (Y page 43). Children in the vehicle

Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is
not equipped with the automatic front-
passenger front airbag deactivation system,
this is indicated by a special 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.
In this case, always fit the rearward-facing
child restraint system to a suitable rear seat
(Y page 64).
Observe the following information under
"Rearward-facing child restraint system" and
"Forward-facing child restraint system" as
well as information on the suitable position-
ing of the child restraint system
(Y page 64).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only if the PASSENGER AIR BAG OFF indicator
lamp is permanently lit (Y page 43) is the
front-passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 64) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. Forward-facing child restraint system If it is absolutely necessary to fit a forward-
facing child restraint system to the front-
passenger seat, always move the front-
passenger seat as far back as possible.
Always make sure that the shoulder belt strap
is correctly routed from the vehicle belt outlet to the shoulder belt guide on the child
restraint system. The shoulder belt strap
must be routed forwards and downwards
from the vehicle belt outlet. If necessary,
adjust the vehicle belt outlet and the front-
passenger seat accordingly.
Always observe the information on suitable
positioning of the child restraint system
(Y page 64) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions. Suitable positioning of the child
