Window curtain air bags
0043are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate of
lateral vehicle deceleration or acceleration,
e.g. in a side impact
R regardless of whether the front-passenger
seat is occupied
R independently of the use of the seat belt
R independently of the front air bags
Window curtain air bags 0043will not deploy in
the event of impacts which do not exceed the
system's preset deployment thresholds for
vehicle acceleration/deceleration. You will
then be protected by the fastened seat belt. Occupant Classification System
(OCS)
How the Occupant Classification Sys-
tem works 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.
The PASSENGER AIR BAG OFF indicator lamp
shows you the current status. If the
PASSENGER AIR BAG OFF indicator lamp is
lit, the passenger air bag is disabled.
The system does not deactivate:
R the side impact air bag
R the pelvis 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.
If the front-passenger seat, the seat cover or the seat cushion are damaged, have the nec- essary repair work carried out at a qualified
specialist workshop.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories
that have been approved by Mercedes-Benz.
Both the driver and the front passenger
should always observe the PASSENGER AIR
BAG OFF indicator lamp as an indication of
whether or not the front passenger is posi-
tioned correctly. Observe also the air bag dis-
play messages that can be displayed in the
instrument cluster (Y page 215). G
WARNING
If the 00730074 indicator lamp illuminates
when an adult or someone larger than a small individual is in the front passenger seat, have the front passenger reposition himself or her-
self in the seat until the 00730074indicator
lamp goes out.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighing as
much as or less than a typical 12-month-old
child in a standard child restraint or if the front passenger seat is classified as being empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 00730074indicator lamp will
illuminate when the engine is started and Occupant safety

The person on the
front-passenger seat:
R

R has been determined
by the system not to
be a child The OCS is malfunctioning.
X Make sure that the front passenger is sitting in a correct, upright
position.
X Have the OCS checked as soon as possible at a qualified spe-
cialist workshop.
X Observe the additional display messages in the multifunction
display (Y page 215). G
WARNING
If the 00730074 indicator lamp illuminates and remains illuminated when the weight of a typical
adult or someone larger than a small individual has been detected on the passenger seat, do not allow any occupant to use the passenger seat until the system has been repaired. Problem
Possible causes/consequences and
0050 0050Solutions The PASSENGER AIR
BAG OFF indicator
lamp does not light up
and/or stays on.
The front-passenger
seat is:
R unoccupied
R occupied with a
weight up to that of a typical twelve-
month-old child in a
standard child
restraint system The OCS is malfunctioning.
X Make sure there is nothing between the seat cushion and the
child seat.
X Make sure that the backrest and base of the child restraint sys-
tem are resting securely on the front-passenger seat. If neces-
sary, adjust the position of the front-passenger seat.
X When installing the child restraint system, make sure that the
seat belt is tight. Do not pull the seat belt tight with the front-
passenger seat adjustment. This could result in the seat belt
being pulled too tightly.
X Check the installation of the child restraint system.
X Make sure that no objects are applying additional weight onto
the seat.
X If the PASSENGER AIR BAG OFF indicator lamp remains off, have
the OCS system checked as soon as possible at a qualified spe-
cialist workshop. Do not transport a child on the front-passenger seat until the OCS has been repaired.
X Observe the additional display messages in the multifunction
display (Y page 215). Occupant safety
51Safety Z

Install the child restraint system in accord-
ance with the manufacturer's instructions.
Attach the child restraint system to both
securing rings.
An incorrectly installed child restraint system
could come loose during an accident and seri- ously or even fatally injure the child.
Child restraint systems or child seat securing
rings that are malfunctioning or damaged as
the result of a collision must be replaced.
ISOFIX is a standardized securing system for
specially designed child restraint systems on
the rear seats. Securing rings for two LATCH- type (ISOFIX) child restraint systems are
installed on the left and right of the rear seats.
Non-LATCH-type (ISOFIX) child seats may
also be used and can be installed using the
vehicle's seat belt system. Install the child
seat according to the manufacturer's instruc- tions.
The securing rings on the rear seats are cov-
ered by an upholstered lining. Installation instructions
0043indicate the
installation location of securing rings 2.
X Fold upholstery cover 0087and the Velcro
fastener down.
X Install the LATCH-type (ISOFIX) child
restraint systems on both securing
rings 0044. Comply with the manufacturer's
instructions when installing the LATCH-
type (ISOFIX) child restraint system. Top Tether G
WARNING
If the rear seat backrests are not locked, they
could fold forwards in the event of an acci-
dent, heavy braking or sudden changes of
direction. As a result, child restraint systems
cannot perform their intended protective
function. Rear seat backrests that are not
locked can also cause additional injuries, e.g. in the event of an accident. This poses an
increased risk of injury or even fatal injury.
Always lock rear seat backrests after instal-
ling a Top Tether belt. Observe the lock veri-
fication indicator. Adjust the rear seat backr-
ests so that they are in an upright position.
If the rear seat backrest is not engaged and
locked, this will be shown in the multifunction
display in the instrument cluster. A warning
tone also sounds.
Top Tether provides an additional connection between a child restraint system, secured
with a LATCH-type (ISOFIX) child seat mount, and the rear seat. This helps reduce the risk of
injury even further.
The Top Tether anchorage points are installed
in the rear compartment behind the head
restraints. X
