Speed-dependent volume
| Speed-dependent volume |
| General |
Automatic volume control is controlled by the car's speed to compensate for background noise that occurs when the car is moving. The function is active at speeds over 60 kph.
| Function |
The main instrument unit (MIU) receives a speed signal from the ABS. MIU sends the information out on the bus where it can be read by the main unit and the volume controlled. The level is raised as the vehicle's speed increases, and lowered as it drops.
