switch to position 1 or 2, the
PASS. AIRBAG OFF indicator lamp located
in the center console comes on for approx.
six seconds and then goes out.

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 PASS. AIRBAG OFF indicator lamp re-
mains 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.

changes depending on the program
mode selected ( Sor C).
!Never change the program mode when
the gear selector lever is out of
