● Select volume settings that allow you to easily hear signals from out-
side the vehicle at all times (e.g. emergency service sirens).
● If the volume is too high, you could damage your hearing. Even if the
volume is too loud for a short period only.

(e.g. due to very quiet audio output from an external audio source), lower
the volume again before switching audio source.
