Introduction
The on-board computer provides you with useful informa-
tion during a journey, including average and current fuel
consumption, average speed, fuel range and driving time.
The following items of information are processed by the on-board
computer and can be shown one after the other on the display in the
instrument cluster.
Fuel range
The estimated fuel range is displayed in km. It shows how far the
vehicle can be driven with the amount of fuel left in the tank,
assuming the same style of driving. The fuel range is displayed in
increments of 10 km.
The fuel range is calculated on the basis of the fuel consumption
over the last 30 kilometres. The fuel range will increase accordingly
if you drive in a more economical manner.
Average fuel consumption
This mode displays the average fuel consumption since the memory
was last cancelled in litres/100 km. If required, you can use this
display to adjust your driving style to achieve the desired fuel
consumption.
Current fuel consumption
The display shows the current fuel consumption in litres/100 km. If
required, you can use this display to adjust your driving style to
achieve the desired fuel consumption.
The computer calculates the fuel consumption every 30 metres. The
display switches to l/h (litres per hour) when the vehicle is
stationary.
Average speed
This mode shows the average speed driven since the memory was
last cancelled (in km/h).
Driving time
This display shows the period of time which has elapsed since the
memory was last cancelled.
Distance covered
This display shows the distance you have covered since the memory
was last cancelled.
