How do you re sync wing mirrors on Volvo s80?

To resync the wing mirrors on a Volvo S80, first ensure that the vehicle is in the "Run" position without starting the engine. Adjust the mirrors to their desired positions using the controls. Then, hold the mirror adjustment switch in the desired direction until the mirrors move to their new positions. If the mirrors still do not sync, you may need to disconnect the battery for a few minutes and reconnect it to reset the system.
