ACCELERATOR CABLE CHECK AND
ADJUSTMENT
1. Turn A/C and lamps OFF.
Inspect and adjust at no load.
2. Warm engine until stabilized at idle.
3. Confirm idle speed is at prescribed value.
Standard value: 850±50 r/min
4. Stop engine (ignition switch OFF).
5. Confirm there are no sharp bends in accelerator cable.
6. Check inner cable for correct slack.
Standard value: 1 - 2 mm
7. If there is too much slack or no slack, adjust play by
the following procedures.
(1) Loosen the adjusting bolt to release the cable.
(2) Move the plate until the inner cable play is at the
standard value, and then tighten the adjusting bolt
to the specified torque.
Tightening torque: 5.0±1.0 N·m

CLUTCH PEDAL INSPECTION AND
ADJUSTMENT
1. Turn up the carpet, etc. under the clutch pedal.
2. Measure the clutch pedal height and the clutch pedal
clevis pin play.
Standard value (A):
202.1 - 206.1 mm
173.5 - 177.5 mm
Standard value (B): 1 - 3 mm

3. If the height of the clutch pedal is outside the standard
value, loosen the setting nut to adjust the pedal height
to the standard value.
Caution
Do not push in the master cylinder push rod at this
time, otherwise the clutch will not operate properly.
4. After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between the clutch pedal (the face of
the pedal pad) and the clutch pedal stopper or toeboard
when the clutch is disengaged are within the standard
value ranges.
Standard value (C): 4 - 13 mm
Standard value (D):
114.3 mm or more
100 mm or more
5. If the clutch pedal free play and the distance between
the clutch pedal and the clutch pedal stopper or toeboard
when the clutch is disengaged do not agree with the
standard values, it is probably the result of either air in
the hydraulic system or a faulty master cylinder, clutch
cylinder or clutch. Bleed the air, or disassemble and inspect
the master cylinder, clutch cylinder or clutch.
6. Turn back the carpet, etc.
BLEEDING
Specified fluid: Brake fluid DOT 3 or DOT 4
Caution
Use the specified brake fluid. Avoid using a mixture
of the specified fluid and other fluid.
