ADD ENGINE COOLANT
| Total capacity |
|---|
| 11.8 liters (12.5 US qts, 10.4 Imp. qts) |
CAUTION:
Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot coolant and steam may be released and cause serious burns.
Note
Before adding coolant, turn the A/C switch off.
Tighten the radiator drain cock plug.
Tighten the 2 cylinder block drain cock plugs.
Add TOYOTA Super Long Life Coolant (SLLC) into the radiator reservoir.
| Capacity |
|---|
| Approximately 5.0 liters (5.3 US qts, 4.4 Imp. qts) |
Tech Tips
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).
Please contact any authorized Toyota dealer, or repairer or another duly qualified and equipped professional for further details.
The thermostat open timing can be confirmed by pressing the inlet radiator hose by hand, and checking when the coolant starts to flow inside the hose.
Further add coolant into the radiator reservoir until it reaches the FULL line.
Press the No. 1 and No. 2 radiator hoses several times by hand, and then check the coolant level.
If the coolant level is low, add coolant.
Using a 6 mm hexagon wrench, install the vent plug.
Bleed air from the cooling system.
Note
Before starting the engine to warm up the engine, turn the A/C switch off.
While idling the engine for approximately 10 minutes, make sure the coolant remains at the FULL line by adding coolant as necessary.
After idling the engine for 10 minutes, add coolant until it reaches the B line.
| Capacity |
|---|
| Approximately 2.5 to 3.5 liters (2.6 to 3.7 US qts, 2.2 to 3.1 Imp. qts) |
|
B Line |
Tech Tips
The B line is the lower edge of the inner wall of the filler neck.
Close the radiator reservoir cap, and run the engine at 1500 to 2000 rpm for 5 minutes.
CAUTION:
Wear protective gloves.
Be careful as the radiator hose are hot.
Keep your hands away from the radiator fans.
Tech Tips
The thermostat open timing can be confirmed by pressing the No. 1 radiator hose by hand, and checking when the SLLC starts to flow inside the hose.
Stop the engine and wait until the coolant cools down to ambient temperature.
Check the coolant level.
If the coolant level is below the FULL line, add coolant until it reaches the FULL line.
ADD AUTOMATIC TRANSMISSION FLUID
INSPECT FOR COOLANT LEAK
CAUTION:
Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Note
Before each inspection, turn the A/C switch OFF.
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Using the 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 head.
ADJUST MILLIMETER WAVE RADAR SENSOR ASSEMBLY (w/ Dynamic Radar Cruise Control System)
CAUTION:
Exposure to radio frequency emissions is hazardous to your health. It is hazardous to be within 20 cm (7.87 in.) of the device's radio frequency aperture.
Note
This device complies with FCC radio frequency emission regulations.
Perform measurements on a level surface.
Make sure that no large pieces of metal are within a 10 m (32.8 ft.) x 14 m (45.9 ft.) area in front of the vehicle. If possible, the surrounding area should also be free of large metal objects.
Before adjusting the radar beam axis, prepare the vehicle as follows.
Check the tire pressure and adjust it if necessary.
Remove all excess weight from the vehicle (luggage, heavy objects, etc.).
w/ Air Suspension:
Adjust the vehicle's height to the standard height.
Check and adjust the vertical direction of the radar sensor.
Remove dust, oil and foreign matter from the radar sensor's level rack.
Set a level on the radar sensor's level rack.
Check that the level's air bubble is within the red frame.
| OK |
|---|
| Level's air bubble is within red frame. |
If the bubble is not within the red frame, use a hexagon wrench to adjust bolt A until the level's air bubble is within the red frame.
Tech Tips
The adjustable range within the red frame of the level is +/-0.2°.
The target angle is +0.2° (upward angle of 0.2°).
| Adjustment Direction | Adjustment Procedure | Adjustment Angle |
|---|---|---|
| Vertical adjustment |
|
For 1 complete turn of screwdriver, sensor moves about 0.12° |
Adjust the reflector height.
Adjust the reflector so that the center of the SST reflector is the same height as the millimeter wave radar sensor.
Tech Tips
Prepare a 10 m (32.8 ft.) string with a sharp-pointed weight (plumb bob) and a 5 m (16.4 ft.) tape measure.
Place the reflector.
From the center of the front bumper (center of the emblem), hang a weight with a pointed tip, and mark point B on the ground.
From the center of the rear bumper (center of the emblem), hang a weight with a pointed tip, and mark point A on the ground.
Using a piece of string that uses point A as a starting point and that passes through point B, make a straight line on the ground ahead of the vehicle 5 m (16.4 ft.) or more from point B.
Tech Tips
Make sure to secure the string (using tape, etc.) when it is taut.
Lightly flick the string with your fingers several times to confirm that the string is aligned above point B.
Using a tape measure, measure 10 mm (0.394 in.) to the left of the 5000 mm (16.4 ft.) position. Place the reflector at that position.
Note
Perform the operation as precisely as possible.
Check the radar beam axis.
When using the intelligent tester:
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
Turn the intelligent tester main switch ON and turn the cruise control main switch ON.
Select "Auto" from the intelligent tester display screen. *1
Select "Radar Cruise" from the display screen.

Select "Next".
Select "Next".
Select "Next".
Note
Turn the cruise control main switch ON before pressing Next.
Make sure there is a distance of at least 20 cm (7.87 inches) between the radar sensor and any nearby individuals.
CAUTION:
Do not come within 20 cm (7.87 inches) of the radar sensor.
Check the following items on the laser cruise divergence data screen.
CAUTION:
While using the intelligent tester's beam axis adjustment mode, the actual direction and angle of the radar sensor may be different from the intelligent tester's data. In such a case, the deviation is displayed on the combination meter's multi-information display.
Confirm that the distance value is approximately 5 m (16.4 ft.).
Tech Tips
A value between 0.0 and 6.3 m (20.7 ft.) is indicated.
If the distance is 0 m (0 ft.), the sensor cannot detect the target. Reconfirm that there is no metal in the specified area in front of the vehicle (refer to the NOTICE at the beginning of this adjustment procedure).
Confirm that the left/right side value is between 0.0 and 6.3°.
Tech Tips
If the distance is 0 m (0 ft.), the sensor cannot detect the target. Reconfirm that there is no metal in the specified area in front of the vehicle (refer to the NOTICE at the beginning of this adjustment procedure).
Check and adjust the horizontal direction of the radar sensor.
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 bolt B until the divergence of the radar beam axis is 0°.
Based on the measured divergence of the beam axis, turn and adjust bolt B for horizontal adjustment of the millimeter wave radar sensor using a hexagon wrench.
| Adjustment Direction | Adjustment Procedure | Adjustment Angle |
|---|---|---|
| Horizontal adjustment |
|
For 1 complete turn of screwdriver, sensor moves about 0.07° |
Tech Tips
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.
