without special
child seat installed
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* (if so equipped) start/stop
button once or twice, the
“PASSENGER AIRBAG OFF” indicator
lamp1 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
Mercedes-Benz Center before seating any
child on the passenger seat.
For more information see (page 294).
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.
Warning!
G
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
passenger front airbag will not deploy only if
the PASSENGER AIRBAG OFF indicator lamp
remains illuminated.
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 front passenger seat until the system
has been repaired.
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 PASSENGER AIRBAG OFF indicator lamp
not to come on during self-test or be contin-
uously lit, indicating that the system is not
functioning.
