3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.
IIt is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in D
position.
6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately
release throttle.
IDuring test, never hold throttle wide open for more than 5
seconds.
Stall revolution:
2,350 - 2,850 rpm
8. Move selector lever to ªNº position.
9. Cool off CVT fluid.
IRun engine at idle for at least one minute.
Line Pressure TestNCAT0027LINE PRESSURE TEST PORTSNCAT0027S01Location of line pressure test ports are shown in the illustration.
IAlways replace pressure plugs as they are self-sealing
bolts.
LINE PRESSURE TEST PROCEDURENCAT0027S021. Check CVT fluid and engine oil levels. If necessary, add fluid
or oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and CVT
fluid reach operating temperature.
CVT fluid operating temperature:
50 - 80ÉC (122 - 176ÉF)

DescriptionNCAT0061The line pressure solenoid valve regulates the oil pump discharge
pressure to suit the driving condition in response to a signal sent
from the TCM.
The line pressure duty cycle value is not consistent when the
closed throttle position switch is ªONº. To confirm the line
pressure duty cycle at low pressure, the accelerator (throttle)
should be open until the closed throttle position switch is
ªOFFº.

lWhen removing or installing trunk lid, place a cloth or other padding on rear fender panels. This pre-
vents vehicle body from being scratched.
lBumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
lTrunk lid adjustment: Adjust at hinge-trunk lid portion for proper trunk lid fit.
lTrunk lid lock system adjustment: Adjust striker so that it is in the center of the lock. After adjustment,
check trunk lid lock operation.
WARNING:
lBe careful not to scratch trunk lid stay when installing trunk lid.
A scratched stay may cause gas leakage.
lThe contents of the trunk lid stay are under pressure. Do not take apart puncture, apply heat or
allow fire near it.
lOpener cable: Do not attempt to bend cable using excessive force.
lAfter installation, make sure that trunk lid and fuel filler lid open smoothly.

REMOVAL AND INSTALLATION
1. Remove manual transaxle from vehicle. Refer to MT section
ªREMOVAL AND INSTALLATIONº.
2. Remove release bearing by pulling bearing retainers out-
ward.
3. Align retaining pin with cavity of clutch housing and tap out
retaining pin.
CAUTION:
lBe sure to apply grease to the clutch components.
Otherwise, abnormal noise, poor clutch disengagement,
or clutch damage may occur. Wipe the excess grease off
completely, because it may cause the clutch compo-
nents to slip and shudder.
lKeep the clutch disc facing, pressure plate, and flywheel
free of oil and grease.
INSPECTION
lReplace the release bearing if it is seized, damaged, faulty
in rotation direction, or has poor aligning function.
lReplace the withdrawal lever if its contact surface is worn
abnormally.
lReplace the clutch lever if its contact surface is worn abnor-
mally.
lReplace the dust seal if it is deformed or cracked.
