Specified capacity:

9.1 liters (9.6 US qts, 8.0 lmp. qts)

HINT:

1. 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 consists of a combination of low phosphates and organic acids).
   

1. Contact your TOYOTA dealer for further details.
   

Slowly pour coolant into the radiator reservoir until it reaches the FULL line.

Press 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.

Install the radiator cap and reservoir cap.

Bleed air from the cooling system.

NOTICE:

Before starting the engine to warm up the engine, turn the A/C switch OFF.

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

   HINT:

   The thermostat open timing can be confirmed by pressing the inlet radiator hose by hand, and checking when the engine coolant starts to flow inside the hose.

   NOTICE:

   When pressing the radiator hoses:

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

2. Maintain the engine speed at 2,000 to 2,500 rpm.
   

3. Press the inlet and outlet radiator hoses several times by hand to bleed air.
   

   NOTICE:

   When pressing the radiator hoses:

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

Stop the engine, and wait until the engine coolant cools down to ambient temperature.

NOTICE:

Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

Check the coolant level in the radiator reservoir.
If the coolant level is low, add SLLC to the radiator reservoir FULL line.

Fill the radiator with coolant and attach a radiator cap tester.

Warm up the engine.

Using a radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf*cm², 17 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and cylinder head.

Before adjusting the radar beam axis, prepare the vehicle as follows:

1. Check the tire pressure and adjust it if necessary.
   

2. Remove all excess weight from the vehicle (luggage, heavy objects, etc. ).
   

Check and adjust the vertical direction of the radar sensor.

1. Remove dust, oil, and foreign matter from the radar sensor's level rack.
   

2. Set a level on the radar sensor's level rack.
   





3. Check that the air bubble is within the red frame on the level.
   

   OK:

   The air bubble is within the red frame on the level.
   If the bubble is not within the red frame, use a hexagon wrench to adjust screw A until the air bubble is within the red frame.
   

   HINT:

   1. The adjustable range within the red frame on the level is + - 0.2°.
      
   2. The target angle is +0.2° (upward angle of 0.2°).
      
   
   

   Result:

   
   

   Adjustment Direction	Adjustment Procedure	Adjustment Angle
   Vertical adjustment	Upward direction: Turn screw A to negative (-) side Downward direction: Turn screw A to positive (+) side	Approx. 1.0° per turn

Adjust the reflector height.

1. Adjust the reflector so that the center of the SST reflector is the same height as the millimeter wave radar sensor.
   

   SST

   09870-60000(09870-60010,09870-60040)
   

   HINT:

   Prepare a 10 m (32.81 ft) string, a string with a sharp-pointed weight (plumb bob), and a 5 m (16.41 ft) tape measure.

Place the reflector.

1. Hang the string (with weight) from the center of the vehicle's rear emblem. Mark the vehicle's rear center point on the ground. Repeat the same procedure for the front of the vehicle.
   





2. Set one end of the 10 m (32.82 ft) string on the vehicle's rear center point. Run the string over the vehicle's front center point to a position 5 m (16.41 ft) beyond the vehicle front center point, as shown in the illustration. Mark the 5 m (16.41 ft) position.
   





3. Using a tape measure, measure 12 mm (0.47 in.) to the left of the 5 m (16.41 ft) position. Place the reflector at that position.
   
   

   
   
   
   

   NOTICE:

   Perform the operation as precisely as possible.

Adjust the radar beam axis.

1. Connect the intelligent tester to the DLC3.
   

2. Turn the engine switch on (IG).
   





3. Turn the intelligent tester main switch on, and turn the cruise control main switch on.
   

   HINT:

   If an error message is displayed on the screen, initialization of the distance control ECU may not be completed. Initialize the distance control ECU (Click here)

   
   
   
   
   
   
   
   
   
   
   

Check and adjust the horizontal direction of the radar sensor.

1. Check that the divergence of the radar beam axis is 0° .
   

   Standard:

   0° (Both right and left)
   

   If the axis is not as specified, use a hexagon wrench to adjust screw B until the divergence of the radar beam axis is 0°.
   





2. Based on the measured divergence of the beam axis, turn and adjust screw B for horizontal adjustment of the millimeter wave radar sensor using a hexagon wrench.
   
   

   Result:

   
   

   Adjustment Direction	Adjustment Procedure	Adjustment Angle
   Horizontal adjustment	Right direction: Turn screw B to positive (+) side. Left direction: Turn screw B to negative (-) side.	Approx. 0.33° per turn

   HINT:

   1. If "LEFT SIDE: 1.0°" is displayed, the divergence is 1.0° in the left direction. Turn screw B approximately 3 turns to the negative (-) side.
      
   2. If the value does not change to 0°, it is possible that the sensor is aiming at something different. Reconfirm that there are no reflective materials in the surrounding area.
      




3. Reset the radar sensor's driving learning values. Prepare a type of metal that can block radio waves, such as aluminum foil. Cover the radar sensor's left half with the aluminum foil for 10 seconds.
   

   NOTICE:

   Be sure to keep the reflector in place and make sure that there is nothing between the sensor's left half and the reflector.

   HINT:

   When the reset is completed, the buzzer sounds for 10 seconds.

4. Disconnect the intelligent tester from the DLC3.
   

Recheck and readjust the vertical direction of the radar sensor.

1. Set a level on the radar sensor's level rack.
   





2. Check that the air bubble is within the red frame on the level.
   

   OK:

   The air bubble is within the red frame on the level.
   

   If the bubble is not within the red frame, use a hexagon wrench to adjust screw A until the air bubble is within the red frame.
   

   HINT:

   1. The adjustable range within the red frame on the level is + -0.2°.
      
   2. The target angle is +0.2° (upward angle of 0.2°).
      
   
   

   Result:

   
   

   Adjustment Direction	Adjustment Procedure	Adjustment Angle
   Vertical adjustment	Upward direction: Turn screw A to negative (-) side Downward direction: Turn screw A to positive (+) side	Approx. 1.0°per turn

Adjust the tire pressure to the correct value range.

Start the engine and charge the battery.

Adjust the fog light aim into the specified range by turning the aiming screw with a screwdriver.
