OCS Self-test 
After turning the SmartKey in the starter
switch to position  1 or  2 or pressing the
KEYLESS-GO start/stop button once or
twice, the  45 indicator lamp
illuminates. If an adult occupant is properly
sitting on the front passenger seat and the
system classifies the occupant as an adult,
the  45  indicator lamp will illuminate
and go out after approximately 6 seconds.
If the seat is not occupied and the system
classifies the front passenger seat as being
empty, the  45 indicator lamp will
illuminate and not go out.
GWarning!
If the  45  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 the “Practical
hints” section ( Y page 308).
GWarning!
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the OCS. The bottom and
back of the child seat must make full contact
with the passenger seat cushion and
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 seats.
BabySmart™ air bag deactivation 
system
The BabySmart™ air bag deactivation system
is standard equipment in Canada.
GWarning!
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. 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 Children 12 years old and under must never
ride in the front seat, except in a Mercedes-
Benz authorized BabySmart™ compatible
child seat, which operates with the
BabySmart™ system installed in the vehicle
to deactivate the front passenger front air
bag when it is installed properly. Otherwise
they will be struck by the air bag when it
inflates in a crash. If this happens, serious
or fatal injury will result.
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

completely eliminate this risk is to never
place a child in a rear-facing child restraint
in the front seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint in a backseat.
RIf you must install a BabySmart™
compatible rear-facing child restraint on
the front passenger seat because
circumstances require you to do so, make
sure the 45 indicator lamp is
illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 45 indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the 45 indicator
lamp while driving to make sure the
45 indicator lamp is illuminated. If
the 45 indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.
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.
RIf you have to place a child in a forward-
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, and secure child restraint with
the vehicle’s seat belt according to the child
seat manufacturer’s instructions.
GWarning!
When using a BabySmart™ compatible child
seat on the front passenger seat, the front
passenger front air bag will not deploy only if
the 45 indicator lamp remains
illuminated.
Please be sure to check the 45
indicator lamp every time you use a
BabySmart™ compatible child seat on the
front passenger seat. Should the 45
indicator lamp go out while the restraint is
installed, please check installation. If the
45 indicator lamp remains out, do not
use the BabySmart™ restraint to transport a
child on the front passenger seat until the
system has been repaired.
Special BabySmart™ compatible child seats,
designed for use with the Mercedes-Benz
system, are required for use with the
BabySmart™ air bag deactivation system.
Please contact an authorized Mercedes-Benz
Center for information on availability. With
the special child seat installed properly, the
front passenger front air bag will not deploy.

illuminated, except with the SmartKey

After turning the SmartKey in the starter

goes out.
