    CVT fluid : Refer to Changing CVT Fluid 

    Fluid capacity : Refer to CHECKING CVT FLUID 

    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. Refer to PRECAUTIONS FOR TCM AND CVT ASSEMBLY REPLACEMENT .
  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 CHECKING CVT FLUID .
  20. Connect negative battery terminal. Refer to BATTERY .
