Resetting The Trip Computer
You may only reset the AVG ECON, FUEL USED and AVG SPEED displays. (You cannot reset Comp/Temp, Instant Econ, Range and OFF Modes.) Press and hold the RESET button for at least 2 seconds, while in a resettable trip function. The reset will acknowledge by the display momentarily flashing all segments ON for a period of a half second. Reset each display individually.
