Voltmeter
The voltmeter shows the voltage in the on-board electrical system. The normal range of values is from 12 to 15 V. If the voltage drops below 12 V when the engine is running, then the power supply system must be checked (battery and generator), if possible, contact a workshop.
When starting the engine, the voltage may drop below 8 V.
Engine oil pressure gauge
This device shows the current engine oil pressure value. If a sudden change occurs while driving, (to a level below 1.8 bar) oil pressure drop, the control lamp will start flashing and the sound signal of the diagnostic unit of the main vehicle systems will turn on at the same time. In this case, you should stop and turn off the engine.
Check the engine oil level and top up if necessary.
If the oil pressure is too low, you cannot continue driving.
Engine oil temperature gauge
Until the engine oil has warmed up, do not force the engine to operate at full power. If the instrument pointer enters the maximum value zone, then it is necessary to reduce the engine speed. In this case, the pointer should return to the scale range corresponding to the engine operating temperature
If it remains in the maximum value zone, you need to stop and turn off the engine, then check the engine oil level. If the oil level is normal, and the oil pressure indicator lamp goes out after starting the engine, you can, avoiding high-speed modes, drive to the nearest workshop.
