Restarting the tire pressure monitor Whe ny ou restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rentl ys et tire pressures as the reference values
for monitoring. In most cases, the tire pressure
monitor will automaticall yd etect the new refer-
ence value sa fte ry ou have changed the tire
pressure. However, yo uc an also set reference
value sm anually as described here. The tire
pressure monitor then monitors the new tire
pressure values. X
