WARNING
Modifications to or work improperly con-
ducted on restraint system components or
their wiring, as well as tampering with inter-
connected electronic systems, can lead to the restraint system snolonger functioning as
intended.
Air bags or Emergenc yTensioning Devices
(ETDs), for example, could deploy inadver-
tently or fail to deploy in accidents although
the deceleration threshold for air bag deploy- ment is exceeded. Therefore, neve rmodify
the restraint systems. Do not tamper with
electronic components or their software.
In this section, you will learn the most impor-
tan tfact sabout the restraint system compo-
nents of the vehicle.
The restraint system consists of:
R Seat belts
R Child restraint systems
Additional protection is provided by:
R SRS (Supplemental Restrain tSystem)
R Air bag system components with:
- PASSENGER AIR BAGO FF indicator lamp
- Front-passenger seat with Occupant
Classification System (OCS)
Although the system sare independent ,their
protective function swork in conjunction with
each other .Not all air bags are always
deployed in an accident.

Occupant safetySafety

If the SmartKey has been removed from the
ignition lock or the Start/Stop button has
been set to position 0,the
00730074 indicator lamp 0043does not light
up. G
WARNING
If the red 0075SRS warning lamp in the
instrument cluster and the 00730074indica-
tor lamp lightu psimultaneously, the OCS is
malfunctioning. The front passenger front air
bag willbed eactivated in this case. Have the
system checked by qualifiedt echnicians as
soon as possible. Contact an authorized
Mercedes-Benz Center.
Only have the seat repaired or replaced at an
authorized Mercedes-Benz Center.
In order to ensure proper operation of the air
bag system and OCS:
R Sit with the seat belt properl yfastened in a
positio nthat is as upright as possible with
yourb ack against the seat backrest.
R When seated, apassenger shouldn ot posi-
tion him/hersel finsuchaway as to cause
the passenger's weight to be lifted from the seat cushio nasthis may resultint he OCS
being unabletoc orrectly approximate the
passenger's weight category.
R Reada nd observe all warnings in this chap-
ter. System self-test The
00730074 indicator lamp illuminates
when you:
R turn the SmartKey to position 1or 2in the
ignition lock
R press the Start/Stop button once or twice
If an adult occupant is properl ysitting on the
passenger seat and the OCS classifies the
occupant as an adult, the 00730074indicator
lamp illuminates and goes out again after
approximately 6seconds.
If the seat is not occupie dand the OCS clas-
sifies the front passenger seat as being unoc-
cupied, the 00730074indicator lamp willi llu-
minate and not go out. G
WARNING
If the 00730074indicator lamp does not illu-
minate, the system is not functioning. You
must contac tanauthorized Mercedes-Benz
Center befor eseatin gany child on the
passenger seat.
For more information, see "Problem swith the
Occupant Classification System"
(Y page 46). G
WARNING
Never place anything betwee nseat cushion
and child seat (e.g. apillow), sinc eitreduces
the effectiveness of the OCS. The underside
and rear side child restraint system must be
placed entirely on the seat cushio nand the
backrest of the front-passenge rseat back-
rest.
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 increasin gprotection for the child.
Follow the manufacturer' sinstructions for
installation of child restraint systems. Occupant safety
