■Automatic Collision Notification
If any airbag deploys, the system is designed to automatically call the Public
Safety Answering Point (PSAP).* The responding agent receives the vehicle’s
location and attempts to speak with the vehicle occupants to assess the level
of emergency. If the occupants are unable to communicate, the agent auto-
matically treats the call as an emer gency, contacts the nearest emergency
services provider to describe the situation, and requests that assistance be
sent to the location.
*: In some cases, the call cannot be made.( P. 580)
■Emergency Assistance Button (“SOS”)
In the event of an emergency, push the “SOS” button to reach the Public
Safety Answering Point (PSAP). The answering agent will determine your
vehicle’s location, assess the emergency, and dispatch the necessary assis-
tance required.
If you accidentally press the “SOS” button, tell the agent that you are not experi-
encing an emergency.
When the engine switch is turned to IGNITION ON mode, the red indicator
light will illuminate for 10 seconds and then the green indicator light will illumi-
nate for 2 seconds, indicating that the syst em is enabled. The indicator lights indi-
cate the following:
●If the green indicator light illuminates and stays on, the system is enabled.
●If the green indicator light flashes, an emergency call is being made (either
automatically or manually).
●If no indicator lights illuminate, the system is not enabled.
●If the red indicator light illuminates any time other than immediately after the
engine switch is turned to IGNITION ON mode, the system may be malfunc-
tioning or the backup battery may be depleted. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
