(f) Repeat the above procedure to bleed the air out of the
brake line for each wheel.
4. BLEED BRAKE ACTUATOR ASSY (W/ VSC)
NOTICE:
After performing the usual air bleeding in the brake system,
if the height or feel of the brake pedal cannot be obtained,
perform air bleeding in the brake actuator assy with a
hand-held tester by following procedures below.
(a) Depress the brake pedal more than 20 times with the en-
gine off.
(b) Connect the hand-held tester to the DLC3, then turn the
ignition switch to the ON position.
NOTICE:
Do not start the engine.
(c) Select ºAIR BLEEDINGº on the hand-held tester.
HINT:
Please refer to the Hand-Held Tester Operator's Manual for fur-
ther details.
(d) Bleed the air out of the regular brake line in ºStep1: In-
creaseº on the hand-held tester display.
NOTICE:

Perform the air bleeding by following the steps dis-
played on the hand-held tester.

Make sure that the brake fluid in the master cylinder
reservoir tank does not become empty.
(1) Connect the vinyl tube to either one of the bleeder
plugs.
(2) Depress the brake pedal several times, then loosen
the bleeder plug of one of the above wheels with the
pedal depressed.
(3) When fluid stops coming out, tighten the bleeder
plug, then release the brake pedal.
(4) Repeat (2) and (3) until all air in the fluid is complete-
ly bled out.
(5) Tighten the bleeder plug certainly.
Torque: 8.3 NVm (85 kgfVcm, 73 in.Vlbf)

NOTICE:

Check the drive belt deflection at the specified point.

When installing a new belt, set its tension value as
specified.

When inspecting a belt which is used for over 5 min-
utes, apply the specification of ºUsed beltº.

When reinstalling a belt which is used for over 5 min-
utes, adjust its belt deflection and tension to the inter-
mediate value of each specification in ºUsed beltº.

The V- ribbed belt tension and deflection value
should be checked after 2 revolutions of engine
cranking.

When using a belt tension gauge, confirm the accura-
cy first by using a master gauge.
7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using the hand-held tester or OBD II scan tool:
(1) Connect the hand-held tester or OBD II scan tool
to the DLC3.
(2) Enter DATA LIST MODE on the hand-held tester or
OBD II scan tool.
Ignition timing: 8 to 12 BTDC
HINT:
Refer to the hand-held tester or OBD II scan tool operator's
manual if you need help to select DATA LIST.
