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.
Make 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.
iFor safety reasons, make sure the hook
has attached to the ring beyond the
safety catch, as illustrated.
