   Engine Oil:

   
   

   Engine	Oil Grade	Oil Viscosity (SAE)
   w/o DPF	ACEA C2, B1, API CF-4 or CF (You may also use API CE or CD)	0W-30 5W-30 10W-30 15W-40 20W-50
   w/ DPF	ACEA C2	0W-30 5W-30

   
   

   Capacity:

   
   

   Item	Capacity
   Drain and refill with oil filter change	4.0 liters (4.2 US qts, 3.5 Imp. qts)
   Drain and refill with out oil filter change	3.6 liters (3.8 US qts, 3.2 Imp. qts)
   Dry fill	4.8 liters (5.1 US qts, 4.2 Imp. qts)

1. Warm up and stop the engine, wait for 5 minutes, and check that the oil level is between the Low and Full marks on the dipstick.
   

   HINT:

   If the oil level is low, check for leaks and add oil to the Full mark.

   NOTICE:

   Do not add oil above the Full mark.

2. Warm up the engine until the coolant temperature is 75°C to 86°C (167°F to 187°F), and confirm that the oil maintenance indicator illuminates when driving the vehicle at 15 km/h (9 mph) or more with an engine speed of 1400 to 2600 rpm.
   

   HINT:

   1. If the oil maintenance warning indicator illuminates during confirmation driving after an oil change, check for an open or close in the engine oil level sensor (Click here). If there is a malfunction, replace the engine oil level sensor (Click here).
      
   2. If the oil maintenance warning indicator illuminates, the engine oil level is correct, and the sensor is functioning normally, then check the wire harness and connectors between the engine oil level sensor and engine control ECM (Click here).
      

1. Tighten the radiator drain cock plug.
   

2. Loosen the air bleed valve 1 and the air bleed valve 2.

3. Add TOYOTA Super Long Life Coolant (SLLC).
   

   Standard Capacity:

   Item	Capacity
   w/o Combustion Type Power Heater	4.5 liters (4.8 US qts, 4.0 Imp. qts)

   NOTICE:

   Never use water as a substitute for engine coolant.

   HINT:

   TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology is a combination of low phosphates and organic acids).

4. Add coolant to the B line of the radiator reserve tank.

5. Squeeze the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
   If the coolant level is low, add coolant.
   

6. Tighten the air bleed valve 1 and the air bleed valve 2.

7. Install the reserve tank cap sub-assembly.
   

8. Start the engine and warm it up.
   

9. Bleed air from the cooling system.
   

   NOTICE:

   1. Before starting the engine, turn the A/C switch off.
      
   2. Adjust the air conditioning temperature setting to MAX (HOT).
      
   3. Adjust the air conditioning blower setting to LO.
      
   
   

   1. Warm up the engine until the thermostat opens. While the thermostat is open, allow the coolant to circulate for several minutes.
      

      HINT:

      Thermostat opening timing can be determined by squeezing the inlet radiator hose, and sensing vibrations when the engine coolant starts to flow inside the hose.

      CAUTION:

      When squeezing the radiator hoses:

      1. Wear protective gloves.
         
      2. Be careful as the radiator hoses are hot.
         
      3. Keep your hands away from the radiator fan.
         

10. Stop the engine, and wait until the engine coolant cools down.
    

11. After the engine has cooled down, check that the coolant level is between the FULL and LOW lines.
    If the coolant level is low, add coolant to the reservoir tank FULL line.

1. Start the engine. Check for engine oil leaks from the connected parts of the oil filter cap and oil filter drain plug.
   

CAUTION:

To avoid the danger of being burned, do not remove the radiator cap sub-assembly while the engine and radiator assembly are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator assembly.

1. Fill the radiator assembly with engine coolant, and attach a radiator cap tester.

2. Pump the tester to 118 kPa (1.2 kgf/cm², 17.1 psi), and then check that the pressure does not drop.
   If the pressure drops, check the hoses, radiator assembly and water pump assembly for leaks. If there are no signs or traces of external engine coolant leaks, check the heater core, cylinder block and head.
