Fuel Tank
There are two alternative methods for calibrating the
level sensor in the fuel tank. Full Fuel Tank Calibra-
tion is an approximate method, while Fuel Multipoint
Calibration provides more precise results. Multipoint
calibration is a prerequisite if the trip computer is to
show fully accurate information.
