June 30, 2011 9:20 am
■
Overheating
In the following situations, 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.
●
The message “HYBRID SYSTEM OVERHEAT” is displayed on the multi-infor-
mation display.
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 engine drive belt while the hybrid
system is operating.
●
Do not loosen the radiator cap while the hybrid system and radiator are hot.
Serious injury, such as burns, may result from hot coolant and steam released
under pressure.
Add coolant if necessary.
Water can be used in an emer-
gency measure if coolant is
unavailable. (

P. 593)
Have the vehicle checked at your nearest Lexus dealer as soon as pos-
sible.
