Noise Emissions

Every eM2 is equipped with an acoustic vehicle alerting system (AVAS). The AVAS makes the minimum noise possible to alert pedestrians, bicyclists, and other non-motorized road users of the presence and approach of the vehicle.

Each vehicle is equipped with two AVAS speakers. One is located at the front of the vehicle, see Fig. and the other is attached on the inside rear of the right-hand frame rail.The general location of the rear AVAS speaker, see Fig..

Each vehicle has a defined AVAS sound, built upon the vehicle noise profile, which cannot be adapted to personal preferences.

The AVAS generates noise when the key is in the ON position and the park brake is released. While driving or when the vehicle is in neutral, sound is broadcast through the front speaker. When the vehicle is in reverse, sound is broadcast through the rear speaker.

When speeding up, the volume of the AVAS sound increases until maximum volume is reached at about 19 mph (30 km/h). This volume is maintained until approximately 60 mph (97 km/h) at which point it turns off. It turns on again when the vehicle slows down to around 20 mph (32 km/h).

The rear speaker will broadcast a beeping sound when the vehicle is in reverse. If the vehicle has been ordered with a backup alarm, this beep will sound like an electric alarm clock. If the vehicle is ordered with no backup alarm, the reverse beep alert will sound like someone regularly striking a high-pitched key on a piano. The back-up volume is set by the factory and cannot be changed; vehicle speed does not affect the back-up sound volume.

Any deactivation of AVAS imperils the safety of other road users and is strongly discouraged.
