■Overheating
If you observe the following, your vehicle may be overheating.
●The display on the engine coolant temperature gauge flashes 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 compartm ent may be very hot, causing serious
injury such as burns.
●Keep hands and clothing away from the fa ns and belt while the engine is running.
●Do not loosen the coolant reservoir cap while the engine and radiator are hot.
Serious injury, such as burns, may resu lt from hot coolant and steam released
under pressure.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency measure if engine coolant
is unavailable. ( P. 5 0 7 )
Have the vehicle checked at your nearest Lexus dealer as soon as pos-
