Special BabySmartTM compatible child seats,
designed for use with the Mercedes-Benz
system, are required for use with the
BabySmartTM 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 4/ indicator lamp : will be
illuminated, except with the SmartKey
removed from the starter switch or with the
starter switch in position 0.
The system does not deactivate the window
curtain air bag and the Emergency Tensioning
Device (ETD).
Self-test BabySmart™ without special
child seat installed
After turning the SmartKey in the starter
switch to position 1 or 2 the 4/
indicator lamp comes on for approximately
6 seconds and then goes out.
If the 4/ indicator lamp should not
come on or is continuously lit, the system is
not functioning. You must see an 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 220).
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 BabySmartTM
air bag deactivation system. Such signal
interference may cause the 4/
indicator lamp not to come on during self-test
or be continuously lit, indicating that the
system is not functioning.
GWarning!
The BabySmartTM 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 BabySmartTM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness off the BabySmartTM air bag
deactivation system. The bottom of the child
seat must make full contact with the front
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to the
child in case of an accident, instead of
protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
