IN-CABIN MICROFILTER : Removal and Installation INFOID:0000000004683699
FUNCTION The fresh air (A) and the recirculated air (B) drawn inside the pas-
senger compartment by the blower fan (1) is kept clean (C) on either
mode by the air conditioner filter (2), located before the evaporator
(3), in the A/C unit assembly.
REPLACEMENT TIMING Replace the air conditioner filter according to the maintenance schedules. Refer to MA-9 .
NOTE:
The air conditioner filter caution label is located inside the glove box door.
REPLACEMENT PROCEDURES 1. Remove the glove box assembly. Refer to IP-11 .
2. Compress the air conditioner filter (1) downward while sliding it to the RH side of the vehicle to release the upper pawl.
3. Move the bottom of air conditioner filter (1) upward as shown to
release the bottom tab, then remove it.
4. Replace the air conditioner filter with new one and in stall the new filter in the A/C unit assembly.
CAUTION:
Make sure that the air cond itioner filter lower tab is fully seated , and that the air conditioner upper
pawl is locked into place securing the new filter into the A/C unit assembly.
5. Install the glove box assembly. Refer to IP-11 .
EXHAUST SYSTEM
EXHAUST SYSTEM : Chec king Exhaust System INFOID:0000000004683700
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.

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.
