weight sensor readings from the front-
passenger seat, remain illuminated
or
go out.
With the 00730074 indicator lamp
illuminated, the front-passenger front air bag
is deactivated. With the 00730074 indicator
lamp out, the front-passenger front air bag is
activated.
When the OCS senses that the front-
passenger seat occupant is classified as an
adult or someone larger than a small
individual, the 00730074 indicator lamp will
illuminate for approximately 6 seconds when
the engine is started and then go out,
indicating that the front-passenger front air
bag is activated.
If the 00730074 indicator lamp is illuminated,
the front-passenger front air bag is
deactivated and will not be deployed.
If the 00730074 indicator lamp is not
illuminated, the front-passenger front air bag
is activated and will be deployed:
R in the event of certain frontal impacts
R if impact exceeds a preset deployment
threshold
R independently of the side impact air bags
If the front-passenger front air bag is
deployed, the rate of inflation will be
influenced by:
R the rate of relevant vehicle deceleration as
assessed by the air bag control unit
R the front passenger's weight category as
identified by OCS
For further information, see "Air bag display
messages" ( Y page 238).G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger
seat. Thus,
we strongly recommend that children be
placed in the rear seats whenever possible.
Regardless 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 anchors
and 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.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front-
passenger seat:
R Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front-passenger seat.
R A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place a child
in a rear-facing child restraint in the front-
passenger seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint on the rear
seat.
R If you install a rear-facing child restraint on
the front-passenger seat, make sure the
00730074 indicator lamp is illuminated,
indicating that the front-passenger front air
bag is deactivated. Should the 00730074
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the 48

X
Have the OCS checked as soon as possible at an authorized
Mercedes-Benz Center.
X Observe the additional display messages in the multifunction
display ( Y page 238). 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

R occupied with a
weight up
to that of a

X
Make sure there is nothing between the seat cushion and the
child seat.
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 00730074 indicator lamp remains off, have the OCS
system checked as soon as
possible at an authorized Mercedes-
Benz Center. Do not transport a child on the front-passenger
seat as long as the OCS is not functioning.
X Observe the additional display messages in the multifunction
display ( Y page 238). G
WARNING
If the 00730074 indicator lamp does not illuminate or remains out with the weight of a typical
12-month-old child in a standard
child restraint or less, or is unoccupied, on the front-passenger
seat, do not transport a child on the front-passenger seat until the system has been repaired. Occupant safety
