If low, check for leaks and add "Toyota Long Life Coolant" or equivalent up to the "FULL" line.
2. CHECK ENGINE COOLANT QUALITY

CAUTION: To avoid the danger of being burned, do not remove the reservoir the cap while the engine and radiator are still hot, as fluid and steam can be blown out under pressure.

b) There should not be any excessive deposits of rust or scale around the reservoir cap or reservoir filler hole, and the coolant should be free from oil.
If excessively dirty, replace the coolant.
