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 such as nearby public phones.
• It may sometimes be difficult to connect to the public Safety Answering Point(PSAP) even in the reception area of the 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 w ill 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 th e “SOS” button panel, indicator lights,
microphone, speaker, DCM, antenna, or any wires connecting the equipment.)
has an abnormality, is damaged or broken, the Emergency Call cannot be made.
• During the Emergency Call, the system makes repeated attempts to connect to
the Public Safety Answering 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 cellular network and the call may finish with-
out connecting. The red indicator 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 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. Contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer.
