I just have the car automatically reset A whenever I fill up with Gas, and reset B whenever it's charged. That way I don't have to remember to reset, and I can get the efficiency data with every fillup/charge cycle.
I think "Trip A" is automatically reset whenever you refill the gas. However, it can be manually reset from the "trip button" on the dashboard.
The owner must configure it to reset. Unlike most of the people that answered the question I use "A" the measure distance on a charge and I use "B" to measure gas milage. The way things are going I probably will not use gas for a year.
I have mine set to have trip A reset when I recharge the battery. And trip B reset to zero when I gas up. The car was delivered with a full tank but I topped off when I got home. I never ran the car using the ICE but the Ice comes on automatically every week or two to insure that the ICE stays lubricated so I assumed that there may be something wrong with the gauge when it remained stuck on full after 1,600 miles. I tried adding gusto the car to see if the gas gauge was broken but all I was able to fit in the tank was 0.04 gallons of gas. I do not anticipate using any gas unless I take a long trip. If I need to use a trip meter it will probably be the "B" trip meter because I just do not use gas anymore
