      HINT:

      • Use of improper coolants may damage the engine cooling system.
      • Use "TOYOTA Super Long Life Coolant" or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology.
      • New Toyota vehicles are filled with TOYOTA Super Long Life Coolant (color is pink, premixed ethylene-glycol concentration is approximately 50 % and freezing temperature is -35° C (-31° F)). When replacing coolant, TOYOTA Super Long Life Coolant is recommended.
      • Observe the coolant level inside the radiator by pressing the inlet and outlet radiator hoses several times by hand. If the coolant level drops, add coolant.
