Checking A/T FluidINFOID:0000000001703158
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Before driving, A/T fluid level can be checked at A/T fluid tem-
peratures of 30 to 50°C (86 to 122°F) using the “COLD” range
on A/T fluid level gauge.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free cloth.
CAUTION:
When wiping the A/T fluid level gauge, always use lint-free
cloth.
e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far
as it will go.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging
pipe using the stopper attached.
f. Remove A/T fluid level gauge and note reading. If reading is at
low side of range, add A/T fluid to the A/T fluid charging pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes.
5. Re-check A/T fluid level at A/T fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on A/T
fluid level gauge.
CAUTION:
• When wiping the A/T fluid level gauge, always use lint-free cloth.
• Firmly fix the A/T fluid level gauge to the A/T fluid charging pipe using the stopper attached.
6. Check A/T fluid condition and make any necessary repairs. Refer to AT-48, "
Inspections Before Trouble
Diagnosis". If the A/T fluid contains frictional material (clutches, bands, etc.), or if the A/T is repaired, over-
hauled, or replaced, inspect and clean the A/T fluid cooler mounted in the radiator. Refer to AT-16, "
A/T
Fluid Cooler Cleaning".
7. Install the removed A/T fluid level gauge into the A/T fluid charging pipe.
CAUTION:
Firmly fix the A/T fluid level gauge to the A/T fluid charging pipe using the stopper attached.
Changing A/T FluidINFOID:0000000001703159
1. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid by removing the drain plug. Reinstall the drain plug to the specified torque.
CAUTION:
Do not reuse drain plug gasket.
4. Refill the transaxle with new specified A/T fluid through the A/T fluid charging pipe. Always refill the tran-
saxle with the same volume of A/T fluid that was drained out.

CVT FLUID
Checking CVT FluidINFOID:0000000001703433
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 installed into the CVT fluid charging pipe, make sure that the CVT
fluid level gauge is securely locked in place.

FLUID CONDITION CHECK
Changing CVT FluidINFOID:0000000001703434
1. Warm up CVT fluid by driving the vehicle for 10 minutes.
• : Vehicle front
• Radiator (2)
• CVT fluid cooler hose [inlet side (3)]
• Transaxle assembly (4)
2. Drain CVT fluid from CVT fluid cooler hose [outlet side (1)] and
refill with new specified NISSAN CVT fluid in the CVT fluid
charging pipe with the engine running at idle speed.
CAUTION:
Only use the specified NISSAN CVT fluid.
3. Refill until new CVT fluid comes out from CVT fluid cooler hose [outlet side (1)].
NOTE:
About 30 to 50% extra fluid will be required for this procedure.
4. Check fluid level and condition. Refer to MA-19, "
Checking CVT Fluid".
CAUTION:
Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid. Refer to CVT-47,
"CONSULT-III Function (TRANSMISSION)".
CVT Fluid Cooler CleaningINFOID:0000000001703435
Whenever a CVT is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can be trapped or become deposit in the CVT fluid cooler. This
debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid.
In either case, malfunction of the newly serviced CVT may occur.
Debris, if present, may deposit as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
CVT FLUID COOLER CLEANING PROCEDURE
1. Identify the CVT inlet and outlet fluid cooler hoses.
2. Position an oil pan under the inlet and outlet cooler hoses.
