Bleeding
1. Check the level of clutch fluid in the reservoir and
replenish if necessary.
Bleeding the damper cylinder (except V6 LHD
model).
2. Remove the rubber cap from the bleeder screw and
wipe clean the bleeder screw. Connect a vinyl tube to
the bleeder screw and insert the other end of the vinyl
tube into a transparent container.
3. Pump the clutch pedal repeatedly and hold it
depressed.
