Fuel consumption, function - GF54.50-P-2007R
MODELS 203 up to 30.6.02, 208 as of 1.8.99, 210 as of 1.7.99, 215, 220 with CODE (494a) USA version
The trip computer allows the average fuel consumption to be displayed:
- "SINCE START" (short-distance memory) and
- "SINCE RESET" (long-distance memory)
Figure 1
Depending on the unit setting (miles/kilometers) and the national variant coding of the instrument cluster (A1) the fuel consumption is displayed in:
- Miles per gallon (Figure 1),
- Liters per 100 km (Figure 2) or
- Kilometers per liter (only if national variant Japan is coded).
Figure 2
Fuel consumption "SINCE START" (short-distance memory), function
- Activate the "SINCE START" display screen via the system selection button (S110s3) and scroll forward/back button (S110s1) of the multifunction steering wheel.
- The display shows the fuel consumption calculated since the last reset of the short-distance memory, as well as the mileage traveled, the average speed and travel time.
Fuel consumption "SINCE RESET" (long-distance memory), function
- Activate the "SINCE RESET" display screen via the system selection button (S110s3) and scroll forward/back button (S110s1) of the multifunction steering wheel.
- The display shows the fuel consumption calculated since the last reset of the long-distance memory, as well as the mileage traveled, the average speed and travel time.
The trip computer calculates the average fuel consumption figures from the mileage traveled and the consumption signal.
The fuel consumption signal uses information on the amount of fuel injected within a specific period.
The instrument cluster (A1) receives this data in the following way:
- The consumption signal is generated by the ME-SFI/CDI control unit (N3/10, N3/9) and transmitted as a message over the engine compartment CAN.
- The distance traveled is determined from the 4 wheel speeds. The signals come from the traction systems control unit (N47) over the engine compartment CAN.
After resetting it may take up to 3 km or up to 2 minutes until sufficient data is available in order to calculate and display the consumptions correctly. During this time, depending on the unit setting (kilometers/miles) and the national variant coding of the instrument cluster (A1), the display shows 5.8 MPG, 40 L/100 km or 2.5 km/L.
It is completely normal for the "since start" display (short-distance memory) and "since reset" display (long-distance memory) to show different values since the two displays are based on different sets of data. The "since start" display (short-distance memory) reacts much more sensitively to the current driving situation than the "since reset" display (long-distance memory).
