Trip computer

The car's trip computer records and calculates vales such as e.g. distance, fuel consumption and average speed whilst driving.

In order to facilitate fuel-efficient driving, information is recorded about both instantaneous and average fuel consumption. The information from the trip computer can be shown in the driver display.

The following meters are included in the trip computer:

  • Trip meter
  • Odometer
  • Instantaneous fuel consumption
  • Distance to empty tank
  • Tourist - alternative speedometer

Trip meter

There are two trip meters, TM and TA.

TM can be reset manually and TA is reset automatically if the car is not used for at least four hours.

The following information is registered while driving:

  • Mileage
  • Driving time
  • Average speed
  • Average fuel consumption.

The values apply from the trip meter's latest reset.


The odometer records the car's total mileage. This value cannot be reset to zero.

Instantaneous fuel consumption

This gauge shows the fuel consumption that the car has at the moment. The value is updated approximately every second.

Distance to empty tank

The trip computer calculates the remaining mileage with the fuel available in the tank.

The calculation is based on the average fuel consumption over the last 30 km and the remaining driveable fuel quantity.

No guaranteed range remains when the gauge shows "----". In which case, refuel as soon as possible.


There may be a slight deviation if the driving style has been changed.

An economic driving style generally results in a longer driving distance.

Tourist - alternative speedometer

The alternative digital speedometer makes it easier to drive in countries where speed limit signs are in a different unit than that shown in the car's instruments.

The digital speed is then shown in the opposite unit to that shown in the analogue speedometer. If the analogue speedometer is graduated in mph, the digital speedometer shows the corresponding speed in km/h and vice versa.
