■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 hood.
CAUTION
■To prevent an accident or injury when inspecting under the hood of your vehicle
●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
injury such as burns.
●Keep hands and clothing away from the fan and other belts while the engine is
running.

Add engine coolant if required.
Water can be used in an emer-
gency measure if engine coolant
is unavailable. (→P. 5 3 1 )
Have the vehicle checked at your nearest Lexus dealer as soon as pos-
sible.
