The oil pressure warning lamp is located in the top right-hand corner. It warns the driver when engine oil pressure is too low.

The lamp is supplied with current in the main instrument unit and grounded via terminal 2 (K20) of the oil pressure sensor.

If the oil pressure is below 0.3-0.5 bar, the oil pressure sensor will close, pin 15 in the main instrument unit will be grounded and the control module will turn on the lamp. At the same time as the central warning lamp comes on, MIU will send a request to SID to activate an acoustic signal if the engine speed is above 310 RPM.
