Speed CalibrationUnder ordinary conditions, the navigation system dis-
tance measuring function will automatically compensate
for minute decreases in wheel and tire diameter caused
by tire wear or low pressure. Speed calibration immedi-
ately restores system accuracy in cases such as when
distance calibration is needed because of the use of tire
chains in inclement weather.EL-488
