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.
• Carefully monitor fluid level in reservoir tank during bleeding operation.
1. Fill master cylinder reservoir tank with new clutch fluid.
2. Connect a transparent vinyl tube and container to the bleeding connector (1) on the CSC.
3. Depress and release the clutch pedal slowly and fully 15 times at an interval of two to three seconds and release the clutch
pedal.
4. Push in the lock pin (1) of the bleeding connector (2), and maintain the position. • RS5F91R transaxle models
CAUTION:
Hold the lock pin in to preven t the bleeding connector from
separating when fluid pressure is applied.

WHEELS : Rotation INFOID:0000000004683838
• Follow the maintenance schedule for tire rotation service intervals. Refer to MA-9 .
• Do not include the T-type spare tire when rotating tires.
CAUTION:
• When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
• Be careful not to tighten wheel nut at torque exceeding the specification to prevent damage of disc rotor.
BRAKE FLUID LEVEL AND LEAKS
BRAKE FLUID LEVEL AND LEAK S : On Board Inspection INFOID:0000000004683839
CHECKING BRAKE FLUID LEVEL
• Make sure the fluid level in the reservoir tank is within the standard (between MAX and MIN lines).
• Visually check around the reservoir tank for fluid leaks.
• If fluid level is excessively low, check brake system for fluid leaks.
• Release parking brake lever and see if brake warning lamp goes off. If not, check brake system for fluid leaks.
BRAKE FLUID LEVEL AND LE AKS : Drain and Refill INFOID:0000000004683840
CAUTION:
• Refill using recommended brake fluid. Refer to MA-14, " Fluids and Lubricants " .
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, immediately wipe th em with cloth and wash it away with water.
• Before working, disconnect connectors of ABS actua tor and electric unit (control unit) or battery
negative terminal.
1. Connect a vinyl tube to bleed valve.
2. Depress the brake pedal, loosen the bleed valve, and gradually remove the brake fluid.Wheel nut : 113 N·m (12 kg-m, 83 ft-lb) SMA829C
