On-board computer
You can call up the following information sequentially on the on-board computer:
  • Date
  • Driving time (hours) from single journey memory
  • Average fuel consumption (ltr./100 km) from single journey memory
  • Average speed (km/h) from single journey memory
  • Distance covered (km) from single journey memory
  • Current fuel consumption (ltr./100 km)
  • Single journey memory summary
  • Total journey memory summary
The single journey memory processes the information on a journey from the time the ignition is switched on until it is switched off. If the journey is resumed within two hours after the ignition is switched off, the new figures are automatically included in the calculation.
Unlike the single journey memory, the total journey memory is not erased automatically. In this way, you can determine the period for which you wish the on-board computer to supply driving information.
With some vehicle functions, you can scroll through the information from the single journey memory in line -1- Fig. 3 using the thumbwheel -B-.
The current fuel consumption can be shown in a bar display Fig. 4. The average fuel consumption (ltr./100 km) from the single journey memory can also be displayed. Electrical energy can be stored in the battery (recuperation) if the vehicle is travelling downhill or coasting in gear (overrun). In this case, the bar will move towards the symbol and will turn green.
Efficiency programme
The efficiency programme can help to save fuel. It evaluates fuel efficiency data and shows a list of auxiliary equipment Link affecting fuel consumption. It also provides economy tips Link for saving fuel. The efficiency programme uses the trip and fuel consumption data from the on-board computer.
To display the efficiency programme, call up the Vehicle functions and select Efficiency programme from the menu. The values in the on-board computer are reset when you clear the data from the efficiency programme.
Note
  • All values stored in the memory are erased if the vehicle battery is disconnected.
  • The measurement units may be different on vehicles for some markets.
