c. Refueling Ready
D When the internal pressure of the fuel tank decreases to a level close to the atmospheric pressure,
the THS ECU opens the fuel filler door. At this time, the multi-information display will show the
"REFUEL READY". Because the THS ECU keeps the fuel vapor-containment valve open during
refueling, the fuel vapor that is created during refueling passes through the fuel vapor-containment
valve and becomes absorbed by the canister. When the fuel filler door is closed after refueling, the
fuel vapor-containment valve closes, in order to seal the fuel tank.
D If 30 minutes elapse after the fuel filler door is opened, the THS ECU closes the fuel
vapor-containment valve and seals the fuel tank in order to prevent the fuel vapor from escaping,
even if the fuel filler door is not closed.
