Security Light
The security light should come on
briefly as the engine is started. If the
system is working normally, the
indicator light turns off. If it does not
come on, have the vehicle serviced
by your dealer.
If the light stays on and the engine
does not start, there could be a
problem with the theft-deterrent
system.
This light is also used to indicate the
status of the anti-theft alarm system
when the ignition is turned off. The
light will flash rapidly if the alarm
system is arming and one or more
of the monitored entry points is not
closed. The light will stay on if the
alarm is arming and all entry points
are closed.
