5-2. Steps to take in an emergency
If the engine overheats:
Stop the vehicle in a safe place and turn off the automatic air
conditioning system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam sub-
sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the engine coolant temperature gauge begins to
fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call your local Lexus
dealer.
After the engine has cooled
down sufficiently, check the
coolant level and inspect the
radiator for any leaks.
