UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel).
Seat belts
Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.MA-27, "Checking Seat
Belts, Buckles, Retrac-
tors, Anchors and Adjust-
ers"
Accelerator pedalCheck the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal.—
Clutch pedalMake sure the pedal operates smoothly and check that it has the proper free play.MA-21
BrakesCheck that the brake does not pull the vehicle to one side when applied. —
Brake pedal and
boosterCheck the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to keep
floor mats away from the pedal.BR-5, "
Inspection and
Adjustment" and BR-18,
"On Board Inspection"
Parking brakeCheck that the lever has the proper travel and make sure that the vehicle is held
securely on a fairly steep hill when only the parking brake is applied.PB-4, "On-Vehicle Ser-
vice"
Automatic transaxle
“Park” mechanismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the se-
lector lever in the “P” position without applying any brakes.—
CVT P (Park) position
mechanismOn a fairly steep hill check that the vehicle is held securely with the selector lever
in the “P” position without applying any brakes.— ItemReference page

Windshield wash-
er fluidCheck that there is adequate fluid in the tank. —
Engine coolant
levelCheck the coolant level when the engine is cold.CO-8, "
Inspection"
A/C condenser,
radiator and hos-
esCheck the front of the condenser and radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the radiator hoses have no cracks, de-
formation, deterioration or loose connections.—
Brake and clutch
fluid levelsMake sure that the brake and clutch fluid levels are between the “MAX” and “MIN”
lines on the reservoirs.BR-8, "
On Board Inspec-
tion" and MA-21, "Checking
Clutch Fluid Level and
Leaks"
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN” lines.
Vehicles operated in high temperatures or under severe conditions require frequent
checks of the battery fluid level.—
Engine drive beltsMake sure that no belt is frayed, worn, cracked or oily.MA-12
Engine oil levelCheck the level on the dipstick after parking the vehicle on a level spot and turning
off the engine.LU-6, "Inspection"
Automatic tran-
saxle fluid levelCheck the level on the dipstick after putting the selector lever in “P” with the engine
idling.MA-19 and MA-22
Exhaust systemMake sure there are no loose supports, cracks or holes. If the sound of the exhaust
seems unusual or there is a smell of exhaust fumes, immediately locate the trouble
and correct it.MA-19
UnderbodyThe underbody is frequently exposed to corrosive substances such as those used
on icy roads or to control dust. It is very important to remove these substances, oth-
erwise rust will form on the floor pan, frame, fuel lines and around the exhaust sys-
tem. At the end of winter, the underbody should be thoroughly flushed with plain
water, being careful to clean those areas where mud and dirt can easily accumu-
late.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the air conditioner after use is normal.
If you should notice any leaks or gasoline fumes are evident, check for the cause
and correct it immediately.—

CHASSIS AND BODY MAINTENANCE
Changing In-cabin MicrofilterINFOID:0000000001704739
1. Remove the glove box assembly. Refer to IP-10 .
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 install the
new filter in the A/C unit assembly.
CAUTION:
Make sure that the air conditioner 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 assem-
bly.
Checking Exhaust SystemINFOID:0000000001704740
Check the exhaust pipes, muffler, and exhaust mounts for improper
attachment, leaks, cracks, damage, chafing, or deterioration.
Checking CVT FluidINFOID:0000000001704741
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.
