will accumulate mileage. For
example, if the vehicle was driven
8 km (5 miles) before it is started
again, and then the retro-active
reset feature is activated, the
display will show 8 km (5 miles). As
the vehicle begins moving, the
display will then increase to 8.2 km
(5.1 miles), 8.4 km (5.2 miles), etc.
