AIRBAG OFF indicator lamp
The 7 indicator lamp will light up for approximately
6 seconds when you turn the electronic key in steering
lock to position 1 or 2.
The 7 indicator lamp stays lit as long as a
BabySmart
TM compatible child seat is properly installed
on the front passenger seat. It indicates that the front
passenger airbag is switched off.
See page 65 for BabySmart
TM deactivation system.
BabySmart
TM is a trademark of Siemens Automotive Corp.
Wa r n i n g !
The BabySmart
TM airbag deactivation system will
ONLY work with a special child seat designed to
operate with it. It will not work with child seats
which are not BabySmart
TMcompatible.
Never place anything between seat cushion and
child seat (e.g. pillow), since it reduces the
effectiveness of the deactivation systems.Follow the manufacturer’s instructions for
installation of special child seats.When using a BabySmart
TM compatible child seat
on the front passenger seat, the front passenger
airbag will not deploy only if the 7 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 systems has
been repaired.
