17. Fill CVT fluid from CVT fluid charging pipe to the specified level.

• 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. Refer to See: Testing and Inspection\Scan Tool Testing and Procedures\CVT RE0F10A\CONSULT-III Function (Transmission).

18. 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) .

19. Check CVT fluid level and condition. Refer to See: Fluid - CVT\Service and Repair\CVT RE0F10A.
20. Connect negative battery terminal. Refer to See: Starting and Charging\Battery\Service and Repair\Removal and Replacement\Coupe (coupe), See: Starting and Charging\Battery\Service and Repair\Removal and Replacement\Sedan (sedan).
