In order to avoid inadvertent activation of the switch, always
remove the ignition key from the passenger air bag ON/OFF
switch.
Turning the passenger air bag back on
The passenger air bag remains OFF until you turn it back ON.
1. Insert the ignition key and turn
the switch to ON.
2. The OFF light will briefly
illuminate when the ignition is
turned to On. This indicates that the
passenger air bag is operational.
If the light is illuminated when the passenger air bag switch is in
the ON position and the ignition switch is in ON, have the
passenger air bag switch serviced at your Ford or Lincoln-Mercury
dealer immediately.
The passenger side air bag should always be ON (the air bag OFF light
should not be illuminated) unless the passenger is a person who meets
the requirements stated either in Category 1, 2 or 3 of the
NHTSA/Transport Canada deactivation criteria which follows.
The safety belts for the driver and right front passenger seating
positions have been specifically designed to function together
with the air bags in certain types of crashes. When you turn OFF your
air bag, you not only lose the protection of the air bag, you also may
reduce the effectiveness of your safety belt system, which was
designed to work with the air bag. If you are not a person who meets
the requirements stated in the NHTSA/Transport Canada deactivation
criteria turning OFF the air bag can increase the risk of serious injury
or death in a collision.
