■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high qua lity ethylene
glycol based non-silicate, non-am ine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant an d 50% deion-
ized water. (Minimum temperature: -35 C [-31F])

■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine/power control unit c oolant reservoir

rized repairer, or any reliable repairer test the cap and check for leaks in the
