■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 o ccupants are unable to communicate, the agent auto-
matically treats the call as an emergency, contacts the nearest emergency
services provider to describe the situ ation, and requests that assistance be
sent to the location.
*: In some cases, the call cannot be made.( P. 498)

WARNING
■When the Emergency Call may not be made
●Any of the followings may occur. In such cases, report to the Public Safety Answering
Point (PSAP) by other means su ch as nearby public phones.
• It may sometimes be difficult to connect to the public Safety Answering Point (PSAP) even in the reception area of t he cellular phone due to the reception level,
or if the line is busy. In such cases, you may not be able to connect to the Public
Safety Answering Point (PSAP) and thus will not be able to make emergency calls and report to the emergency departments even though the system tries to con-
nect to the Public Safety Answering Point (PSAP).
• When the vehicle is out of the cellular phone service area, the Emergency Call cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator lights,
microphone, speaker, DCM, antenna, or any wires connecting the equipment.) has an abnormality, is damaged or brok en, the Emergency Call cannot be made.
• During the Emergency Call, the system makes repeated attempts to connect to
the Public Safety Answerin g Point (PSAP). However, if it cannot connect to the Public Safety Answering Point (PSAP) due to poor radio wave reception, the sys-
tem may not be able to connect to the ce llular network and the call may finish with-
out connecting. The red indi cator light will blink for approximately 30 seconds to indicate this disconnection.
• This device may not function if a shock is applied to it.
●If the 12-volt battery’s voltage decreases or there is a disconnection, the system may
not be able to access the Public Safety Answering Point (PSAP).
■When replacing DCM to a new one
ERA-GLONASS have to be activated. Contac t any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
