Rwhen securing a child in a child restraint
system on the front-passenger seat, you
must:
- move the front-passenger seat as far
back as possible
- use a child restraint system that is
suitable for the age, size and weight of
the child
- observe the manufacturer's installation
instructions in order to install and secure
the child restraint system correctly.
R for children larger than the typical 12-
month-old child, the passenger front air bag
is activated.
Deployment of the driver front air bag does
not mean that the front-passenger front air
bag also should have deployed. The OCS may
have determined:
R that the seat was empty or occupied by a
person with a weight up to or less than that
of a typical 12 month-old child seated in a
standard child restraint
R that the seat was occupied by a small
person (e.g. a young teenager or a small
adult) or a child that weighs more than a
typical 12 month old child in a child
restraint system
These are examples of when OCS disables the
front-passenger front air bag. This occurs
even though the impact fulfills the criteria for
deployment of the driver's front air bag.
If the key has been removed from the ignition
lock or is in position 0, indicator lamp
42 : does not light up.
GWarning
If the red + SRS warning lamp in the
instrument cluster and the 42
indicator lamp light up simultaneously, OCS is
malfunctioning. The front-passenger front air
bag is disabled in this case. Have the system
checked as soon as possible by qualified
technicians. 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 do not place any objects with a total weight
of more than 4.4 lb(2 kg) in the parcel net
on the back of the front-passenger seat.
OCS may otherwise be unable to correctly
assess the occupant's weight category.
R do not place any objects under or near the
front-passenger seat.
R do not hang or fasten any objects on the
seats.
R do not store any objects, such as books,
between the front-passenger seat and the
center console or the front-passenger door.
R do not slide the front-passenger seat
backwards against any hard objects.
R sit with the seat belt fastened correctly and
in a position that is as upright as possible
with your back against the backrest.
R while seated, an occupant should not
position him/herself in such a way as to
cause the occupant's weight to be lifted
from the seat bottom as this may result in
the OCS being unable to correctly
approximate the occupant's weight
category.
R read and observe all warnings in this
chapter.
Occupant safety45SafetyBA 164.8 USA, CA Edition B 2011; 1; 2, en-USd2sboikeVersion: 3.0.3.52010-04-21T15:08:44+02:00 - Seite 45Z

System self-test
The 42 indicator lamp
illuminates when you:
R turn the SmartKey to position 1 or 2 in the
ignition lock
R press the KEYLESS-GO Start-Stop button
once or twice
If an adult occupant is properly sitting on the
passenger seat and the OCS classifies the
occupant as an adult, the 42
indicator lamp illuminates and goes out again
after approximately 6 seconds.
If the seat is not occupied and the OCS
classifies the front-passenger seat as being
unoccupied, the 42 indicator
lamp will illuminate and not go out.
GWarning!
If the 4 2 indicator lamp does
not illuminate, 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, see "Problems with the
occupant classification system"
( Y page 47).
GWarning
Never place anything between seat cushion
and child seat (e.g. a pillow), 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.
