Average
Average fuel consumption is calculated from the last resetting.
Note
There may be a slight error in the reading if a fuel-driven heater* has been used.
Average speed
The average speed is calculated for the driving distance driven since the last reset to zero.
Instantaneous
The information for current fuel consumption is updated continuously - approximately once per second. When the car is driven at low speed the consumption is shown per time unit - at a higher speed it is shown related to mileage.
Different units (km/miles) can be selected for the display - see the section "Change unit".
Range - distance to empty tank

The trip computer shows the approximate distance that can be driven with the fuel quantity remaining in the tank.
No guaranteed range remains when the heading Distance to empty shows "----".
In which case, refuel as soon as possible.
The calculation is based on the average fuel consumption over the last 30 km and the remaining driveable fuel quantity.
Note
There may be a slight error in the reading if the driving style has been changed.
An economic driving style generally results in a longer driving distance. For more information on how fuel consumption can be influenced, see Volvo Car Corporation's Environmental Philosophy.
Digital speed displayOnly for combined instrument panel "Digital".
Only for combined instrument panel "Digital".
The speed is shown in the opposite unit (kmh/mph) in relation to the main instrument. If it is calibrated in mph then the trip computer shows the corresponding speed in km/h and vice versa.
Resetting with "Analog"
