system.
Check to see if steam is coming out from the engine area.
If you see steam:
Stop the engine and carefully lift the hood.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Remove the engine compartment cover. (P. 555)
Check if the cooling fan is operating.
If the fans are operating:
Wait until the temperature of the engine (shown on the
instrument cluster) begins to fall and then stop the engine.
If the fans are not operating:
Stop the engine immediately and call your local Lexus
dealer.
After the engine has cooled
down, check the engine coolant
level and inspect the cooling
system for leaks.
