Warning!
G
The BabySmart
TM1
air bag 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 air bag will not deploy only
if the56indicator lamp (

remains illuminated.
Please be sure to check
the56indicator lamp every time
you use the special system child seat.
Should the56indicator lamp go out
while the restraint is installed, please check

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
the56indicator lamp (

not to come on during self-test or be contin-
uously lit, indicating that the system is not
functioning.
