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 and call your local Lexus dealer.

After the engine has cooled down sufficiently, check the coolant level and inspect the radiator core (radiator) for any leaks.

If the engine compartment cover needs to be removed.

Add engine coolant if required.

Water can be used as an emer- gency measure if engine coolant is unavailable.

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

 - 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.

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 engine is running.

• Do not loosen the radiator cap while the engine and radiator are hot.

Serious injury, such as burns, may result from hot coolant and steam released under pressure.

NOTICE

 - When adding engine coolant

Wait until the engine has cooled down before adding coolant.

When adding coolant, do so slowly. Adding cold coolant to a hot engine too quickly can cause damage to the engine.
