ON-VEHICLE MAINTENANCE
FLUID LEVEL
1. Clean the area around the reservoir and the reser-

2. Check the fluid level. If the level is near or below
the "MIN" mark, add clutch fluid to the "MAX"
mark.
Fluid specification:
DOT-3 or DOT-4
(FMVSS 116, or SAE J1703)
PEDAL HEIGHT
Inspection
Measure the distance from the upper center of the
pedal pad to the firewall and ensure that the distance
is within specification.
Pedal height A:
216.5—221.5 mm (8.524—8.720 in)
Adjustment
To adjust the pedal height, loosen locknut and turn
stopper bolt or clutch switch.
PEDAL FREEPLAY
Inspection
Depress the pedal lightly by hand and measure the
freeplay to ensure that it is within specification.
Pedal freeplay: 5—13 mm (0.20—0.51 in)
Adjustment
1. Adjust the free play by loosening locknut C and
turning push rod D.
2. Check that the distance from the floor to the cen-
ter of the upper surface of the pedal pad is as
specified or more when the clutch is fully dis-
engaged.
Disengagement height B:
LHD 68 mm (2.7 in)
RHD 85 mm (3.3 in)
3. Tighten locknut C after adjustment.
