R If you install arear-facin gchild restraint on
the front-passenge rseat, make sure the
000E0013 indicator lamp is illuminated,
indicating that the front-passenger fron tair
bag is deactivated. Should the 000E0013
indicator lamp not illuminat eorgoout while
the restraint is installed, please check
installation .Periodically check the
000E0013 indicator lamp while driving to
make sure that the 000E0013indicator
lamp is illuminated. If the 000E0013
indicator lamp goes out or remains out, do
not transport achild on the front-passenger
seat until the system has been repaired.
Ac hild in arear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates.
R If you place achild in aforward-facing child
restraint on the front-passenger seat:
- move the seat as far back as possible
- use the proper child restraint
recommended for the age, size and
weight of the child
- secure child restraint with the vehicle's
seat belt according to the child seat
manufacturer's instructions
R For children larger than the typical 12-
month-old child, the front-passenger front
air bag may or may not be activated. G
WARNING
If the red 0021SRS warning lamp in the
instrument cluster and the 000E0013
indicator 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-Ben zCenter.
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, apassenger should not
position him/herself in such away as to
cause the passenger' sweight to be lifted
from the seat cushion as this may result in
the OCS being unable to correctly
approximat ethe passenger' sweight
category.
R Read and observe all warnings in this
chapter. If the SmartKey is removed from the ignition
lock or is in position 0,PASSENGER AIR BAG
OFF indicator lamp 001Adoes not light up.
The Occupant Classification System (OCS)
categorize sthe occupant on the front-
passenge rseat using aweight sensor.
The front-passenger fron tair bag is
deactivated automatically for certain weight
categories.
The PASSENGER AI RBAG OFF indicator lamp
shows yo uthe current status.
The system does not deactivate:
R the side impact ai rbag
R thew indow curtain air bag
R theE me rgency Tensioning Devices Occupant safety

To be classified correctly, the frontp
assenger
must sit:
R wit hthe seat belt fastened correctly
R in ap ositio nthat 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
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 PASSENGER AIR
BAG OFF indicator lamp as an indication of
whether or not the front passenger is
positioned correctly. Observe also the air bag
displaym essages that can be displayed in the
instrumentc luster (Ypage 219).
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 achild restraint system.
R is occupied by asmall individual, such as a
young teenager or asmall adult.
R is occupied by achild in achild restraint
system whose weight is greater than that
of at ypical twelve montho ld child.
These are examples of when the OCS
deactivates the front-passenger front air bag.
Deactivation takes place although the
collision fulfills the criteria for deploying the
driver's air bag.
For further information ,see "Air bag display
messages" (Y page 219). System self-test G
WARNING
If the 000E0013indicator lamp does not
illuminate, the system is not functioning. You
must contac tanauthorized Mercedes-Benz
Center befor eseatin gany child on the front
passenger seat. G
WARNING
Never place anything betwee nseat cushion
and child seat (e.g. apillow), 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 PASSENGER AIR BAG OFF indicator lamp
lights up:
R if you turn the SmartKey in the ignition lock
to position 1or 2
R if an adult is seated properly on the front-
passenger seat and the OCS classifies the
occupant as an adult
The PASSENGER AIR BAG OFF indicator
lamp goes out again after approximately six
seconds.
If the seat is not occupied and the OCS
detects that the front-passenger seat is
empty, the PASSENGER AIR BAG OFF
indicator lamp will continue to light up. The
PASSENGER AIR BAG OFF indicator lamp
will not go out.

The ETDsa re triggered depending on the type
and severit yofanaccident:
R in the event of ahead-on or rear-end
collision if the vehicle decelerates or
accelerates rapidly in alongitudinal
direction during the initial stages of the
impact.
R in the event of aside impact if the vehicle
decelerates or accelerates rapidly in a
lateral direction on the side opposite to the
impact.
R in certain situation swhere the vehicle rolls
over if the system determines that it can
provide additional protection.
If the ETDsa re deployed, you will hear abang,
and asmall amount of powder may also be
released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicat ethat there
is af ire in the vehicle. The dust might cause
some temporary breathin gdifficult yfor
people with asthma or other breathing
trouble. To avoid this, you may wish to get out of the vehicle as soon as it is safe to do so.
You can also open the window to allow fresh
air to enter the vehicle interior. The
0021SRS
warning lamp lights up.
If the seat belt is also equipped with aseat
belt forc elimiter and this is triggered, the
forc eexerted by the seat belt on the vehicle
occupant is reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which take on apart of the deceleration force.
This results in the force exerted on the
occupant being distributed over agreater
area. Children in the vehicle
Child restraint systems
Important safety notes G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible.R egardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchor sand
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children ,should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child. 56
