42 indicator lamp : will be
illuminated, except with the SmartKey
removed from the starter switch or with the
starter switch in position 0.
GWarning!
If the red SRS indicator lamp + in the
instrument cluster and the 42
indicator lamp are lit at the same time, there
is a malfunction in the OCS. 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-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:
RDo not place more than 4.4 lb (2 kg) into
the parcel net on the back of the front
passenger seat. Otherwise, the OCS may
not be able to properly approximate the
occupant weight category.
RDo not place objects under and/or around
the front passenger seat.
RDo not hang anything from or attach any
items to the seats.
RDo not stuff objects such as books between
the front passenger seat and the center
console or front passenger door.
RDo not move the front passenger seat
backwards against stiff objects.
RSit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
RWhile 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.
RRead and observe all warnings in this
chapter.
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 42 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 42 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 42 indicator lamp
will illuminate and not go out.
GWarning!
If the 42 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 305).
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.

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 42 indicator lamp remains
illuminated.
Please be sure to check the 42
indicator lamp every time you use a
BabySmart™ compatible child seat on the
front passenger seat. Should the
42 indicator lamp go out while
the restraint is installed, please check
installation. If the 42 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.
The 42 indicator lamp : will be
illuminated, except with the SmartKey
removed from the starter switch or with the

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 42 indicator lamp
comes on for approximately 6 seconds and
then goes out.
If the 42 indicator lamp should
not come on or is continuously lit, the system

authorized Mercedes-Benz Center before
seating any child on the front passenger seat.
More information can be found in the
“Practical hints” section (Y page 305).
GWarning!
Do not place powered-on laptops, mobile
phones, electronic tags such as those used in
ski passes and like electronic devices on the
front passenger seat. Signals from such
devices may interfere with the BabySmart™
air bag deactivation system. Such signal
interference may cause the 42
indicator lamp not to come on during self-test.
The SRS indicator lamp + and/or the
42 indicator lamp could be
continuously lit, indicating that the system is
not functioning. The front passenger front air
bag could deploy inadvertently or fail to
deploy in an accident.
GWarning!
The BabySmart™ air bag deactivation system
will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart™
compatible.

damage the seat belt and impair its
effectiveness, and/or cause damage to the
door and/or door trim panel. Such damage
is not covered by the Mercedes-Benz
Limited Warranty.
Damaged seat belts must be replaced.
Contact an authorized Mercedes-Benz
Center.
Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale 7 will always illuminate for
6 seconds to remind you and your passengers
to fasten your seat belts.
If the driver’s seat belt is not fastened when
the engine is started, an additional warning
chime will sound. The warning chime goes out
after approximately 6 seconds or once the
driver’s seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened with
front doors closed,
Rthe seat belt telltale 7 remains
illuminated for as long as either the driver’s
or front passenger’s seat belt is not
fastened.
Rand if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt telltale
7 starts flashing and a warning chime
sounds with increasing intensity for a
maximum of 60 seconds or until the
driver’s and front passenger’s seat belt are
fastened.

restraint appropriate to the age and size of
the child.XMake sure the infant or child is properly
secured at all times while the vehicle is in
motion.GWarning!
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child’s unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned by these
parts.
GWarning!
