Trip meters reset themselves

Today I noticed that my MPG per tank display was higher than yesterday. I then noticed that both trip meters had reset themselves at the beginning of my commute today. I'm wondering if the battery may have gone weak, but I had no trouble starting. I do notice that if I have the accessory position turned on that when I turn on the ignition the display will show 'Check charging system'. Is this normal? I do have the smart key.

EDIT. I will continue this in the master thread on this issue.

5 or 6 threads on it.

 

The system seems to be set so when the engine is turned off your trip is over and a new one starts when you restart the engine. That is what my truck does. I intend to use my Garmin on long trips. I am not sure the Navigation system is as good as the Garmin in the Toyota nor is the average speed calculations etc.

and if I am correct as soon as you put gas in it it starts over too

 

Yes it recalculates your maximum range based upon fuel in tank and average speed.
