5-2. Steps to take in an emergency CAUTION n To prevent an accident or injury when inspecting under the hood of your vehicle l If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The engine compartment may be very hot, causing serious injuries such as burns. l Check that the indicator on the "POWER" switch and the "READY" indicator are off. l For vehicles with a hybrid system, there are times when the gasoline engine auto- matically starts to run or the cooling fans suddenly start to operate. Do not touch or approach the rotating parts of the belt or fans. Doing so may lead to fingers, clothes or tools getting caught, resulting in injury. l Do not loosen the radiator cap, or the coolant reservoir cap while the hybrid sys- tem and radiator are hot. Serious injury, such as burns, may result from hot coolant and steam released under pressure. NOTICE n When adding engine/power control unit coolant Wait until the hybrid system has cooled down before adding engine/power control unit coolant. When adding coolant, do so slowly. Adding cool coolant to a hot hybrid system too quickly can cause damage to the hybrid system. 644 CT200h_U (OM76004U)
