Rindependently of seat belt use
R independently of the front air bags
Window curtain air bags : will not deploy in
impacts with deceleration rates which do not
exceed the system’s preset deployment
thresholds for vehicle deceleration or
acceleration. You will then be protected by
the seat belt.
Occupant Classification System
(OCS)
How the occupant classification
system works
The Occupant Classification System (OCS) is
standard equipment in the USA.
OCS categorizes the occupant on the front-
passenger seat by means of a weight sensor.
The front-passenger front air bag is
automatically deactivated for certain weight
categories. The respective status can be
recognized by the 45 indicator lamp.
With the 45 indicator lamp
illuminated, the front-passenger front air bag
is deactivated.
The system does not deactivate:
R the side impact air bag
R the pelvis air bag
R the window curtain air bag (Coupe)
R the front-passenger head bag (Cabriolet)
R the Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
R with the seat belt properly fastened
R in a position that is as upright as possible
with the back against the seat backrest
R with their feet on the floor
If the front-passenger's weight is transferred
to another object in the vehicle (e.g. by
leaning on armrests), OCS may not be able to
approximate the occupant's weight category.
If the front passenger seat, the seat cover, or
the seat cushion are damaged, have the
necessary repair work carried out at an
authorized Mercedes-Benz Center.
For reasons of safety, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should observe the 45 indicator lamp
to determine whether or not the front
passenger is positioned correctly.GWarning
If the 45 indicator lamp illuminates
when an adult or someone larger than a small
individual is in the passenger seat, have the
passenger position him/herself in the seat
until the 45 indicator lamp goes out.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighing as
much as or less than a typical 12-month-old
child in a standard child restraint or if the front
passenger seat is classified as being empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 45 indicator lamp will
illuminate when the engine is started and
remain illuminated. This indicates that the
front passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 45 indicator lamp will illuminate
when the engine is started and remain
illuminated. This indicates that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat occupant is classified as
being heavier than the weight of a typical 12-
month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
45 indicator lamp will illuminate for
approximately 6 seconds when the engine is

BabySmart™ air bag deactivation
system
How the air bag deactivation system
functions
The BabySmart™ system is standard
equipment in Canada.
GWarning
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you always secure children in the rear
seats. Regardless of seating position, children
12 years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child.
Secure the infant restraint system or child
restraint system, using:
R the vehicle's seat belt
R the seat belt and a Top Tether belt
R the LATCH-type (ISOFIX) child seat mount
and a Top Tether belt
The child restraint system must be installed
and secured correctly, observing the
manufacturer's installation 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. Observe the following
important information if it is necessary to
carry a child on the front-passenger seat:
R Children under 12 years may only sit in the
front-passenger seat if they are seated in a
child restraint system which is compatible
with BabySmart™ and approved by
Mercedes-Benz. If the child restraint
system is installed properly, the front-
passenger front air bag is deactivated in
conjunction with the BabySmart™ system.
Otherwise, the child could be struck by the
air bag when it inflates in a crash. This could
lead to serious or fatal injury.
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 it is necessary to install a BabySmart™-
compatible rear-facing child restraint
system on the front-passenger seat, make
sure the 45 indicator lamp is
illuminated. This indicates that the front-
passenger front air bag is deactivated. If the
45 indicator lamp does not light up
or goes out when the child restraint system
is installed, check the anchorages of the
restraint system. Periodically check the
45 indicator lamp while driving to
make sure the 45 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.

front-passenger seat will be seriouslyOccupant safety47SafetyBA 207 USA, CA Edition B 2011; 1; 3, en-USd2sboikeVersion: 3.0.3.62010-05-20T10:38:09+02:00 - Seite 47Z

injured or even killed if the front-passenger
front air bag inflates.
R If you have to place a child in a forward-
facing child restraint system on the front-
passenger seat, you must:
- 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 instructionsGWarning
The BabySmart™ air bag disabling system
ONLY works with specially adapted child
restraint systems. It does not work with child
restraint systems that are not compatible with
BabySmart™.
Never place anything between the seat
cushion and the child restraint system (e.g. a
cushion), as this reduces the effectiveness of
the BabySmart™ air bag deactivation system.
The underside of the child restraint system
must lie against the seat cushion of the front-
passenger seat. In the event of an accident,
an incorrectly installed child restraint system
could injure the child instead of offering
protection.
Observe the manufacturer's instructions
when installing special child restraint
systems.
GWarning
When using a BabySmart™-compatible child
restraint system on the front-passenger seat,
the front-passenger front air bag is only
disabled if the 45 indicator lamp is
illuminated.
Check the 45 indicator lamp
repeatedly, every time you use a
BabySmart™-compatible child restraint
system on the front-passenger seat. Should
the 45 indicator lamp not illuminate
or go out while the restraint is installed,
please check installation. If the 45
indicator lamp remains out, do not use the
BabySmart™ child restraint system to carry a
child on the front-passenger seat until the
system has been repaired.
Special child restraint systems which are
compatible with BabySmart™ are necessary
for deactivating the front-passenger front air
bag. When the special child restraint system
which is compatible with BabySmart™ is
installed correctly and is recognized by the
sensor system in the front-passenger seat,
the front-passenger front air bag is
deactivated. In this case, 45 indicator
lamp : illuminates. If you have any
questions regarding the special child
restraint systems which are compatible with
BabySmart™, consult an authorized
Mercedes-Benz Center.
If the key has been removed from the ignition
lock or is in position 0, indicator lamp
45 : does not light up.
The system does not deactivate:
R the side impact air bag
R the pelvis air bag
R the front passenger head bag (Cabriolet)
R the window curtain air bag (Coupe)
R the Emergency Tensioning Devices
