InspectionINFOID:0000000003806504
CHECKING CVT FLUID
The fluid level should be checked with the fluid warmed up to 50 to 80°C (122 to 176°F). The fluid level check
procedure is as follows:
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20°C (68°F), it takes about 10
minutes for the CVT fluid to warm up to 50 to 80°C (122 to
176°F).
3. Park the vehicle on a level surface.
4. Apply parking brake firmly.
5. With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.
6. Pull out the CVT fluid level gauge from the CVT fluid charging
pipe after pressing the tab on the CVT fluid level gauge to
release the lock.
7. Wipe fluid off the CVT fluid level gauge. Insert the CVT fluid
level gauge rotating 180° from the originally installed position,
then securely push the CVT fluid level gauge until it meets the
top end of the CVT fluid charging pipe.
CAUTION:
When wiping away the CVT fluid level gauge, always use
lint-free paper, not a cloth rag.
8. Place the selector lever in “P” or “N” and check that the fluid
level is within the specified range.
CAUTION:
When reinstalling CVT fluid level gauge, insert it into the
CVT fluid charging pipe and rotate it to the original installa-
tion position until securely locked.

STALL TEST
STALL TEST
Inspection and JudgmentINFOID:0000000003806506
INSPECTION
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the
CVT fluid temperature is 50 to 80°C (122 to 176°F). Inspect the
amount of CVT fluid. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test.
NOTE:
It 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. While holding down the foot brake, gradually press down the
accelerator pedal.
7. Quickly read off the stall speed, and then quickly remove your
foot from the accelerator pedal.
CAUTION:
Never hold down the accelerator pedal for more than 5 sec-
onds during this test.
8. Move the selector lever to the “N” position.
9. Cool down the CVT fluid.
CAUTION:
Run the engine at idle for at least 1 minute.
10. Repeat steps 6 through 9 with selector lever in “R” position.

INSPECTION
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80°C
(122 to 176°F), then inspect the amount of CVT fluid and replenish if necessary.
NOTE:
The CVT fluid temperature rises in the range of 50 to 80°C (122 to 176°F) during 10 minutes of driv-
ing.
3. After warming up CVT, remove the oil pressure detection plug
and install the joint pipe adapter (SST: KV31103600), adapter
(SST: 25055000), oil pressure gauge set (commercial service
tool).
CAUTION:
When using the oil pressure gauge, be sure to use the O-
ring attached to the oil pressure detection plug.
4. Securely engage the parking brake so that the tires do not turn.
5. Start the engine, and then measure the line pressure at both idle
and the stall speed.
CAUTION:
 Keep the brake pedal pressed all the way down during
measurement.
 When measuring the line pressure at the stall speed, refer
to TM-306, "
Inspection and Judgment".
6. After the measurements are complete, install the oil pressure
detection plug and tighten to the specified torque below.
CAUTION:
 Never reuse O-ring.
 Apply CVT fluid to O-ring.

PRECAUTIONS
Precaution for Procedure without Cowl Top Cover
INFOID:0000000003802519
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions For Xenon Headlamp ServiceINFOID:0000000003802520
WARNING:
Comply with the following warnings to prevent any serious accident.
 Disconnect the battery cable (negative terminal) or the power supply fuse before installing, remov-
ing, or touching the xenon headlamp (bulb included). The xenon headlamp contains high-voltage
generated parts.
 Never work with wet hands.
 Check the xenon headlamp ON-OFF status after assembling it to the vehicle. Never turn the xenon
headlamp ON in other conditions. Connect the power supply to the vehicle-side connector.
(Turning it ON outside the lamp case may cause fire or visual impairments.)
 Never touch the bulb glass immediately after turning it OFF. It is extremely hot.
CAUTION:
Comply with the following cautions to prevent any error and malfunction.
 Install the xenon bulb securely. (Insufficient bulb socket installation may melt the bulb, the connec-
tor, the housing, etc. by high-voltage leakage or corona discharge.)
 Never perform HID circuit inspection with a tester.
 Never touch the xenon bulb glass with hands. Never put oil and grease on it.
 Dispose of the used xenon bulb after packing it in thick vinyl without breaking it.
 Never wipe out dirt and contamination with organic solvent (thinner, gasoline, etc.).
Working with HFC-134a (R-134a)INFOID:0000000003802521
CAUTION:
 CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. These refrigerants
must never be mixed, even in the smallest amounts. Compressor malfunction is likely occur if the
refrigerants are mixed.
 Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. Compressor malfunction is likely to occur if lubricant other than that specified is used.
 The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precautions must be observed:
- Cap (seal) immediately the component to minimize the entry of moisture from the atmosphere when
removing refrigerant components from a vehicle.
- Never remove the caps (unseal) until just before connecting the components when installing refrig-
erant components to a vehicle. Connect all refrigerant loop components as quickly as possible to
minimize the entry of moisture into system.
- Use only the specified lubricant from a sealed container. Reseal immediately containers of lubricant.
Lubricant becomes moisture saturated and should not be used without proper sealing.
- Never allow lubricant (NISSAN A/C System Oil Type S) to come in contact with styrene foam parts.
Damage may result.
General Refrigerant PrecautionINFOID:0000000003802522
WARNING:
 Never breath A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant.
