CVT FLUID : Checking CVT Fluid (RE0F08A) INFOID:0000000004803426
FLUID LEVEL CHECK
Fluid level should be checked with the fluid warmed up to 50 ° to 80 °C (122 ° to 176 °F).
1. Check for fluid leakage.
2. With the engine warmed up, drive the vehicle to warm up the CVT fluid. 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 and set the parking brake.
4. With engine at idle, while depressing brake pedal, move the selector lever throughout the entire shift range and return it to
the “P” position.
5. Press the tab on the CVT fluid level gauge to release the lock and pull out the CVT fluid level gauge from the CVT fluid charg-
ing pipe.
6. Wipe fluid off the CVT fluid level gauge. Then rotate the CVT fluid level gauge 180 ° and re-insert it into the CVT charging pipe
as far as it will go.
CAUTION:
Always use lint free paper towels to wipe fluid off the CVT
fluid level gauge.
7. Remove the CVT fluid level gauge and check that the fluid level is within the specified range as shown. If the fluid level is at or
below the low side of the range, add the necessary specified
NISSAN CVT fluid through the CVT charging pipe.
CAUTION:
• Only use specified NISSAN CVT fluid.
• Do not overfill the CVT.
8. Install the CVT fluid level gauge to the CVT fluid charging pipe until it locks. CAUTION:
When CVT fluid level gauge is in stalled into the CVT fluid charging pipe, make sure that the CVT
fluid level gauge is securely locked in place.

CLUTCH FLUID
CLUTCH FLUID : Air Bleeding Procedure INFOID:0000000004683730
CAUTION:
Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the affected
area with water.
NOTE:
• Do not use a vacuum assist or any other type of pow er bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.
