Fill the brake reservoir with brake fluid and bleed the clutch system.

Torque:

8.3 N*m{85 kgf*cm, 73 in.*lbf}

Depress the brake pedal more than 20 times with the engine off.

Connect the intelligent tester to the DLC3, and turn the ignition switch on (IG).

NOTICE:

Do not start the engine.

Select AIR BLEEDING on the intelligent tester.

HINT:

Refer to the intelligent tester operator's manual for further details.

Bleed the air out of the suction line.

NOTICE:

1. Perform the bleeding at the right front wheel and right rear wheel.
   
2. Bleed the air by following the steps displayed on the intelligent tester.
   

1. Connect a vinyl tube to the bleeder plug at the right front wheel or the right rear wheel.
   

2. Loosen the bleeder plug.
   

3. Operate the brake actuator to bleed the air using the intelligent tester.
   

   NOTICE:

   Release the brake pedal at this time.

   HINT:

   This operation stops automatically after 4 seconds.

4. Check if the operation has stopped by referring to the intelligent tester display.
   

5. Temporarily tighten the bleeder plug.
   

6. Repeat the 4 previous steps until all air in the fluid is completely bled out.
   

7. Tighten the bleeder plug.
   

   Torque:

   8.3 N*m{85 kgf*cm, 73 in.*lbf}

8. Repeat all of the above procedures for the right rear wheel to bleed the air out of the suction line.
   

Bleed the air out of the pressure reduction line.

NOTICE:

1. Perform the bleeding at the 4 wheels.
   
2. Bleed the air by following the steps displayed on the intelligent tester.
   

1. Connect a vinyl tube to either one of the bleeder plugs.
   

2. Loosen the bleeder plug.
   

3. Using the intelligent tester, operate the brake actuator assembly, completely depress the brake pedal and hold it there.
   

   NOTICE:

   1. During this procedure, the pedal will feel heavy, but completely depress it so that the brake fluid comes out of the bleeder plug.
      
   2. Hold the brake pedal depressed. Do not depress and release the pedal repeatedly.
      

   HINT:

   The operation stops automatically after 4 seconds. When performing this procedure continuously, set an interval of at least 20 seconds.

5. Repeat the 3 previous steps until all air in the fluid is completely bled out.
   

6. Tighten the bleeder plug.
   

   Torque:

   8.3 N*m{85 kgf*cm, 73 in.*lbf}

7. Repeat all of the above procedures for the other wheels to bleed the air out of the pressure reduction line.
   

Check the fluid level and add fluid if necessary.

Fluid:

SAE J1703 or FMVSS No. 116 DOT3
