Toyota Yaris: If Trouble Arises / Overheating
If the high engine coolant temperature warning light turns on,
the vehicle loses power, or you hear a loud knocking or pinging
noise, the engine is probably too hot.
If the high engine coolant temperature warning light turns on:
- Drive safely to the side of the road and park off the right-of-way.
- Put a vehicle with an automatic transaxle in park (P), a manual
transaxle in neutral.
- Apply the parking brake.
- Turn off the air conditioner.
- Check whether coolant or steam is escaping from the engine compartment.
If steam is coming from the engine compartment
Do not go near the front of the vehicle. Stop the engine.
Wait until the steam dissipates, then open the hood and start the
engine.
If neither coolant nor steam is escaping
Open the hood and idle the engine until it cools.
- Make sure the cooling fan is operating, then turn off the engine after
the temperature has decreased.
- When cool, check the coolant level.
If it is low, look for coolant leaks
from the radiator and hoses.
If you find a leak or other damage, or if coolant is still leaking:
Stop the engine and call your Toyota dealer.
- Cooling fan
- Cooling system cap
- Coolant reservoir
If you find no problems, the engine is cool, and no leaks are
obvious:
Carefully add coolant as required.
WARNING
Pull over to a safe location, then switch the ignition to off and
make sure the fan is not running before attempting to work near the
cooling fan
Working near the cooling fan when it is running is dangerous. The fan
could
continue running indefinitely even if the engine has stopped and the engine
compartment temperature is high. You could be hit by the fan and seriously
injured.
Do not remove either cooling system cap when the engine and
radiator are hot
When the engine and radiator are hot, scalding coolant and steam may
shoot out under pressure and cause serious injury.
Open the hood ONLY after steam is no longer escaping from the engine
Steam from an overheated engine is dangerous. The escaping steam could
seriously burn you.
NOTICE
- If the cooling fan does not operate while the engine is running,
the engine
temperature will increase. Stop the engine and call your Toyota dealer.
- If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged unless
repairs are made. Consult your Toyota dealer.
Do not push-start your Toyota.
You cannot start a vehicle with an automatic transaxle by pushing it.
WARNING
Never tow a vehicle to start it
Towing a vehicle to start it is dangerous...
