| Main odometer (A1h4) | The distance covered is determined from the 4 wheel speeds which are transmitted by the traction systems control module. | Liquid crystal display | GF54.30-P-3015A |
| Electronic speedometer (A1p8) | GF54.30-P-4000A | ||
| Function of stepper motor | GF54.30-P-3009A | ||
| Tachometer (A1p5) | The speed signal comes from the engine control module. | Function of stepper motor | GF54.30-P-3009A |
| ECT gauge (A1p1) | This display is a plateau display, i.e. the pointer stops on 95°C at temperatures between 95°C and 115°C. Temperatures in this range are still not critical. The correct temperature is only displayed again from a temperature of 116°C. This prevents the driver being disturbed by the display, for example, at high outside temperatures. The warning range starts at 116°C. The coolant temperature signal comes from the engine control module. |
