How can I check the runtime/millage on my 2000 e4 Gem Car?

When I turn the vehicle off, the display reads 145 and then 3134 with an hourglass shape next to those numbers. Is that the run time information?

The Battery Discharge indicator, does several functions:
At key on with the parking brake released, it will indicate the percentage of charge on the battery. It will then alternate between MPH and battery status. Once the key is turned off the display will show the mileage and the hourglass figure will light.

for owners manuals for the gem I found this site most helpful.

Just paste it to you browser without the asterisk
