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.

CAUTION:
Replace O-ring with new ones at the final stage of the operation when installing.
1. Remove drain plug from oil pan.
2. Remove drain plug gasket from drain plug.
3. Install drain plug gasket to drain plug.
CAUTION:
Never reuse drain plug gasket.
4. Install drain plug to oil pan. Refer to TM-321, "
Exploded View".
5. Fill CVT fluid from CVT fluid charging pipe to the specified level.
CAUTION:
Use only Genuine NISSAN CVT Fluid NS-2. Never mix with other fluid.
Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.
When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.
Sufficiently shake the container of CVT fluid before using.
Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid.
6. With the engine warmed up, drive the vehicle in an urban area.
NOTE:
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).

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.
