Average consumption and average speed
The values displayed are based on the distance
travelled since the last reset to “zero”.
You can set the starting time for a measurement
before or during the trip.
Switching the ignition off does not reset the meas-
urements. It is therefore possible to collect values
over long periods.
Disconnecting the car ba ttery will cause these
memories to be erased.
Tire pressure
The Tire pressure function of the on-board
computer displays the ti re pressures dependent
on temperature in the four wheels. You can watch
the tire pressure rise and fall while driving.
The display is only for information.
f To correct the tire pressures, always use the
displayed values from the “Info pressure”
display in the tire pressure menu.
