Make sure the cooling fan is operating, then turn off the engine after
the temperature has decreased.

If Trouble Arises
■If you find no problems, the engine is cool, and no leaks are
obvious:
Carefully add coolant as required (→P. 425).
WARNING
■ Pull over to a safe location, then switch the ignition to off and
make sure the fan is not running befo re 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 cool-
ing system inspected. The engine could be seriously damaged unless
repairs are made. Consult your Toyota dealer.
