■Overheating
If you observe the following, your vehicle may be overheating.
●The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
●Steam is coming from under the engine hood.
WARNING
■To prevent an accident or injury when inspecting under the engine
hood of your vehicle
●If steam is seen coming from under the engine hood, do not open the
engine hood until the steam has subsided. The engine compartment may
be very hot, causing serious injury such as burns.
●Keep hands and clothing away from the fan and other belts while the
engine is running.
●Do not loosen the radiator cap while the engine and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
