Control devices (Audi 100 C3)

Speedometer

On the speedometer (see picture) the daily trip meter and the total trip meter are located. The lowest digit of the counters indicates hundreds of meters. The daily trip meter values are reset by pressing the button at the bottom of the speedometer.

Tachometer

Tachometer (see picture) shows the engine speed value. The actual engine speed value is obtained by multiplying the tachometer reading by 100. It is permissible to briefly increase the engine speed above 6300 rpm (red sector of the scale). To set the time on an analog clock, press the knob (indicated by the arrow in the figure) and turn it.



Setting the time on a digital watch is done using two buttons located to the left and right of the watch (see picture). Left button (1) – hours, right button (2) – minutes.

Fuel level indicator

Pointer (see picture) works when the ignition is on.



If the arrow points to the reserve sector (R), then there are still about 12 liters of fuel left in the tank.

Coolant temperature gauge



Pointer (see picture) works only when the ignition is on. The coolant temperature gauge scale is divided into sectors:



Cold sector
If the pointer is in the cold sector, do not overload the engine!

Normal sector
At the operating temperature of the coolant, the pointer of the indicator should be in this sector. It is permissible for the pointer to deviate further to the right until the coolant overheating indicator lamp flashes.

Overheating warning light

If the indicator light starts flashing while driving, it means the coolant level is low or the temperature is too high. In this case, you should stop immediately, turn off the engine and eliminate the cause of overheating.
