running, this indicates the
temperature of the coolant.
Range
When the engine isrunning , this indicates
the distance which can still be travelled with thefuel remaining in the tankbased on the average
fuel consumption over the
last few miles/kilometres
travelled.

This value may vary following a change
in the style of driving or the relief,resulting in a large variation in the current fuel consumption.
If you only add a few litres, the value
displayed will be incorrect. Therefore,you must fill the tank whenever possible.
