The fuel gauge only works when the ignition is on. Error in fuel gauge readings (6 in illustration 13.1) is minimal when the car is in a strictly horizontal position, and increases when the car is moving on winding or hilly roads. When the pointer enters the red area at the beginning of the scale, it means that the reserve fuel supply is being used (approximately 10.5 l) and is accompanied by the yellow indicator lamp in the form of a fuel pump on the right above the scale. On some models, an additional sound signal is given, and the message "Fill up! Power reserve... km" is additionally displayed on the instrument cluster display. In this case, refuel at the first opportunity, since operating the car with a low fuel reserve can lead to interruptions in engine operation when driving uphill or downhill, as well as to damage to the catalytic converter due to misfires. When there is a reserve fuel reserve, the additional heater is automatically switched off. If the engine runs unstable due to a low fuel reserve, the power steering, as well as all auxiliary systems for the driver and vehicle dynamics control systems, may be switched off.
