R
while seated, an occupant should not
position him/herself in such a way as to
cause the occupant's weight to be lifted
fro mt he seat cushion as this may result in
the OCS being unable to correctly
approximate the occupant's weight
category.
R read and observe all warnings in this
section. If the SmartKey has been removed from the
ignition lock or is in position
0,
42 indicator lamp:does not
light up.
The Occupant Classification System (OCS)
categorizes the occupant on the front-
passenger seat using a weight sensor. The
front-passenger front air bag is deactivated
automatically for certain weight categories.
42 indicator lamp:shows you
the current status. If
42 indicator lamp:lights up,
the front-passenger air bag is disabled.
The system does not deactivate:
R the side impact air bag
R the window curtain air bag
R the Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in a position that is as upright as possible
with their back against the seat backrest
R with their feet on the floor The OCS weight sensor reading is affected if
the occupant's weight is transferred, e.g. by
leaning on the armrest.
In addition, the occupant weight may appear
to increase or decrease due to the following:
R
objects hanging on the seat
R objects lodged underneath the seat
R objects lodged between the seat and the
center console
R objects lodged between the seat and the
door
R other passengers exerting weight on the
seat
R objects applying pressure to the back of
the seat
Make sure that the seat always has clearance
in all directions.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at a
qualified specialist workshop.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should always observe the 42
indicator lamp to determine whether or not
the front passenger is positioned correctly.
Also observe the air bag display messages,
which appearint he instrumentcluster
(Y page 220).
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy.
The OCS may have detected that the seat:
R is empty or occupied by the weight of a
typical child up to twelve months old,
seated in a child restraint system
R is occupied by a small individual, such as a
young teenager or a small adult
R is occupied by a child in a child restraint
system whose weight is greater than that
of a typical twelve month old child. Occupant safety
49Safety Z
These are examples of when the OCS
deactivates the front-passenger fronta
ir bag.
Deactivation takes place although the
collision fulfills the criteria for deploying the
driver's air bag.
System self-test G
WARNING
If the 42indicator lamp does
not illuminate, the system is not functioning.
You must contac tanauthorized Mercedes-
Benz Center before seating any child on the
fron tpassenger seat. G
WARNING
Never place anything between seat cushion
and child seat (e.g. a pillow), since it reduces
the effectiveness of the OCS .The underside
and rear side child restraint system must be
placed entirely on the seat cushion and the
backrest of the front-passenger seat
backrest.
If necessary, adjust the tilt of the passenger
seat backrest.
An incorrectly mounted child seat could cause
injuries to the child in case of an accident,
instead of increasing protection for the child.
Follow the manufacturer's instructions for
installation of child restraint systems.
The 42 indicator lamp lights up:
R if you turn the SmartKey in the ignition lock
to position 1or 2
R if you press the KEYLESS-GO Start/Stop
button once or twice on vehicles with
KEYLESS-GO
R if an adulti s seated properly on the front-
passenger seat and the OCS classifies the
occupant as an adult
The 42 indicator lamp goes
out after approximately six seconds.
If the seat is not occupied and the OCS
detects that the front-passenger seat is
empty, the 42 indicator lamp
will continue to light up. The 42
indicator lamp will not go
out.
For more information aboutt he OCS, see
"Problems with the Occupant Classification
System" (Y page 51). 50

All seat belts except the driver's seat belt are
equipped with a special seat belt retractor to
securely fasten child restraint systems in the
vehicle. Further information can be found
under "Special seat belt retractor"
(Y page 62). For more information about releasing the seat
belt with release button
?, see "Releasing
seat belts" (Y page 58).

R
you engage the belt tongue in the belt
buckle and you then turn the SmartKey to
position 2in the ignition lock.
R the SmartKey is in position 2in the ignition
lock and you then engage the belt tongue

retraction force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. You can switch the seat-belt
adjustment on and off in the on-board
computer (Y page 210).
The seat-belt adjustment is an integral part of
the PRE-SAFE ®

WARNING
If the child restraint system is not fitted
correctly on a suitable seat, it may not fulfil
its protective function. In the event of an
accident, sharp braking or a sudden change
in direction, the child may not be held
securely.T he child could thus be seriously or
even fatally injured. For this reason, when
fitting a child restraint system, observe the
manufacturer's installation instructions and
the correct use of the child restraint system.
Child restraint systems should preferably be
fitted on the rear seats. The child is generally
better protected there.
The entire base of the child restraint system
must always rest on the seat cushion.
Therefore, never place objects, e.g. a cushion,
under the child restraint system.
Only use child restraint systems with the
original cover designed for them. Only replace
damaged covers with genuine covers.
We recommend that you use the child
restraint systems which have been
recommended for Mercedes-Benz. G
WARNING
Infants and small children should never share
a seat belt with another occupant. In the event
of an accident, they could be crushed
between the occupant and seat belt.
Ac hild's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not face or neck.Ab ooster seat
may be necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap-shoulder belt
fits properly without a booster.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat
belt to prevent the child restraint from becoming a projectile in the event of an
accident.
G
WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. Achild's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts. G
WARNING
Do not carry heavy or hard objects in the
passenger compartment or cargo
compartmentu nless they are firmly secured
in place.
Unsecured or improperly positioned cargo
increases a child's risk of injury in the event
of
R strong braking maneuvers
R sudden changes of direction
R an accident Children in the vehicle
