When the engine switch is turned to IGNITION ON mode, the red indi-
cator light comes on for 2 seconds then turns off. Afterward, the green
indicator light comes on, indicating that the service is active.
The following indicator light patterns indicate specific system usage con-
ditions:
●Green indicator light on = Active service
●Green indicator light flashing = Safety Connect call in process
●Red indicator light (except at vehicle start-up) = System malfunction
(contact your Lexus dealer)
●No indicator light (off) = Safety Connect service not active
■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. The
responding agent receives the vehicle’s location and attempts to speak
with the vehicle occupants to assess the level of emergency. If the occu-
pants are unable to communicate, the agent automatically treats the
call as an emergency, contacts the nearest emergency services pro-
vider to describe the situation, and requests that assistance be sent to
the location.
