The following may indicate that your vehicle is overheating.
Correction procedures
1. Stop the vehicle in a safe place and turn off the air conditioning system, and then stop the engine.
2. If you see steam: Carefully lift the hood after the steam subsides.
If you do not see steam: Carefully lift the hood.
3. After the engine has cooled down sufficiently, inspect the hoses and radiator core (radiator) for any leaks.

If a large amount of coolant leaks, immediately contact your Toyota dealer.
4. The coolant level is satisfactory if it is between the "FULL" and "LOW" lines on the reservoir.

5. Add coolant if necessary.
Water can be used in an emergency if coolant is unavailable.
If water was added in an emergency, have the vehicle inspected at your Toyota dealer as soon as possible.

6. Start the engine and turn the air conditioning system on to check that the radiator cooling fan operates and to check for coolant leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on immediately after a cold start. Confirm that the fan is operating by checking the fan sound and air flow. If it is difficult to check these, turn the air conditioning system on and off repeatedly. (The fan may not operate in freezing temperatures.)
7. If the fan is not operating: Stop the engine immediately and contact your Toyota dealer.
If the fan is operating: Have the vehicle inspected at the nearest Toyota dealer.
8. Check if "Engine Coolant Temp High Stop in a Safe Place See Owner's Manual" is shown on the multi-information display.
If the message does not disappear: Stop the engine and contact your Toyota dealer.
If the message is not displayed: Have the vehicle inspected at the nearest Toyota dealer.
