TM
without special
child seat installed
After turning key in starter switch to
position1 or2, the
7
indicator lamp
located in the center console lights up for
approximately 6 seconds and then goes
out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized Mer-
cedes-Benz Light Truck Center before
seating any child on the front passenger
seat.
More information can be found in the
“Practical hints” section (page 244).
Warning!
G
The BabySmart
TM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the 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.
When using a BabySmart
TM compatible
child seat on the front passenger side seat,
the front passenger airbag will not deploy
only if the
7
indicator lamp remains il-
luminated.
Warning!
G
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the passenger seat until the system has
been repaired.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
front passenger seat. Signals from such de-
vices may interfere with the BabySmart
TM
system. Such signal interference may cause
the
7
indicator lamp not to come on
during self-test or be continuously lit, indi-
cating that the system is not functioning.
