Useful information
i This Operator's Manual describes all

Overview of occupant safety
In this section, you will learn the most impor-
tant facts about the restraint system compo-
nents of the vehicle.
The restraint system consists of:
R seat belts
R child restraint systems
R LATCH-type (ISOFIX) child seat anchors
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R NECK-PRO head restraints/NECK-PRO
luxury head restraints
R air bag system components with:
- PASSENGER AIR BAG OFF indicator lamp
- front-passenger seat with Occupant
Classification System (OCS)
The different air bag systems work independ-
ently of each other. The protective functions
of the system work in conjunction with each
other. Not all air bags are always deployed in an accident. G
WARNING
Modifications to or work improperly conduc-
ted on restraint system components or their
wiring, as well as tampering with interconnec- ted electronic systems, can lead to the
restraint systems no longer functioning as
intended.
Air bags or Emergency Tensioning 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, never modify
the restraint systems. Do not tamper with
electronic components or their software.
i For information on infants and children
traveling with you in the vehicle restraint
systems for infants and children, see "Chil-
dren in the vehicle" (Y page 61).42
Occupant safetySafety

If the SmartKey is removed from the ignition
lock or is in position 0, the PASSENGER AIR
BAG OFF indicator lamp does not light up. G
WARNING
If the red 0075SRS warning lamp in the
instrument cluster and the 00730074indica-
tor lamp light up simultaneously, the OCS is
malfunctioning. The front passenger front air
bag will be deactivated in this case. Have the system checked by qualified technicians 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 properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R When seated, a passenger should not posi-
tion him/herself in such a way as to cause the passenger's weight to be lifted from theseat cushion as this may result in the OCS
being unable to correctly approximate the
passenger's weight category.
R Read and observe all warnings in this chap-
ter. System self-test The PASSENGER AIR BAG OFF indicator lamp
lights up if you:
R turn the SmartKey to position 1or 2in the
ignition lock
R press the KEYLESS-GO Start/Stop button
once or twice on vehicles with KEYLESS-GO
When an adult is sitting correctly on the front-
passenger seat and is categorized by the OCS system as an adult, the PASSENGER AIR BAG
OFF indicator lamp lights up and goes off
again after approximately six seconds.
If the seat is not occupied and the OCS sys-
tem classifies the front-passenger seat as
being empty, the PASSENGER AIR BAG OFF
indicator lamp will continue to light up and not go out. G
WARNING
If the 00730074indicator lamp does not illu-
minate, the system is not functioning. You
must contact an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.
For more information about the OCS, see
"Problems with the Occupant Classification
System" (Y page 53). G
WARNING
Objects between the seat surface and the
child restraint system could affect OCS oper- ation. This could result in the front-passengerair bag not functioning as intended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forwards- facing child restraint system must, as far as
possible, be resting on the backrest of the
front-passenger seat. Always comply with thechild restraint system manufacturer's instal-
lation instructions. 52
