Mazda MX-30 2020 Owner's Manual page 488

The Emergency call system has a special built-in battery so that it can operate even
if the power supply from the vehicle is cut such as in an accident.
Heed the following cautions. If the Emergency call system is not used correctly it
may not operate.
If the built-in battery power is low due to natural discharge and the system
determines that there is a problem, the Emergency call system cannot be used. If
the system determines that there is a problem, the indicator light (red) in the
Emergency call switch turns on to notify the driver. Have the vehicle inspected at
an expert repairer (we recommend an Authorised Mazda Repairer). Refer to
Indicator light/Beep sound on page 7-11.
NOTE
The Emergency call system can be used when the power switch is switched ON.
There are two ways the Emergency call system makes calls; automatically or
manually.
The Emergency call system may not make a connection under the following
conditions or depending on the use environment. If the Emergency call system
does not connect, make a call from another telephone such as the nearest
available public telephone.
The vehicle is outside of a mobile phone network area
The vehicle is in a weak radio wave transmission environment (such as inside
tunnels, underground parking areas, shadow of buildings, and mountain areas)
The vehicle does not receive an impact of a certain level or more even if an
accident has occurred.
An extremely serious collision occurs resulting in damage to the Emergency call
system.
The position information cannot be obtained when signals cannot be received
from the GNSS satellites, however, voice calls are possible.
When a voice call is made by the Emergency call system, the audio system is
muted so that it does not interfere with the call.
It may take some time for the call centre to respond after the Emergency call
system first starts operating.
If you are unable to respond to an operator's questions after the voice call begins,
the operator may proceed with emergency procedures at their own discretion.
Even if it is difficult for you to hear the operator's voice, your voice may be heard
by the call centre. Continue explaining your circumstances.
If the Emergency call system operates while you are making a call with your mobile
phone using Bluetooth
It may not be possible to receive a call using the Bluetooth
while the Emergency call system is operating.
A voice call with an operator may not be possible if the speaker or microphone is
broken. If the speaker or microphone is broken, always have the vehicle inspected
at an expert repairer (we recommend an Authorised Mazda Repairer).
