CAUTION CAUTION D Do not smoke, cause spark or allow open flames when refueling. The fumes are flammable. D Make sure the cap is tightened securely to prevent fuel spillage in case of an accident. D When opening the cap, do not remove the cap quickly. In hot weather, fuel under pressure could cause injury by spraying out the filler neck if the cap is suddenly removed. 21p031c D Use only a genuine Toyota fuel tank cap for replacement. It is designed to regulate fuel tank pressure. D Insert the fuel nozzle fully, or fuel may splash out. 2. To remove the fuel tank cap, turn the cap slowly counterclockwise, then pause slightly before removing it. After removing the cap, hang it on the cap hanger. It is not unusual to hear a slight swoosh when the cap is opened. When installing, turn the cap clockwise till you hear a click. If the cap is not tightened securely, the malfunction indicator lamp comes on. Make sure the cap is tightened securely. The indicator lamp goes off after driving several times. If the indicator lamp does not go off, contact your Toyota dealer as soon as possible. 36
