 Press and hold the Autocheck UP button and verify that the correct
country code is displayed (eg GB, EU, SA or AU). This is determined by
the coding plug and establishes if fuel & range calculations are
performed in gallons, litres, miles or kilometres.

 Release the UP button , then press and hold the Autocheck DOWN button
and verify that the appropriate range calibration adjustment is

Note that you may encounter an 'aF' code at this step if the fuel usage
signal from the ECU is not detected by the Autocheck / Trip computer.
