GENERAL MAINTENANCE
PFP:00000
Explanation of General Maintenance
ALS000D7
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform
checks and inspections themselves or have their NISSAN dealers do them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the
vehicle, etc.
Item
Reference page
Tires
Check the pressure with a gauge, including the spare, at least once a month
and always prior to a long distance trips. Adjust to the specified pressure if nec-
essary. Check carefully for damage, cuts or excessive wear.
—
Wheel nuts
When checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.
—
Windshield
Clean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary.
—
Tire rotation
Tires should be rotated every 12,000 km (7,500 miles).
Wheel alignment and
balance
If the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed.
,
Windshield wiper
blades
Check for cracks or wear if they do not wipe properly.
—
Doors and engine
hood
Check that all doors and the engine hood operate smoothly as well as the trunk
lid and back hatch. Also make sure that all latches lock securely. Lubricate if
necessary. Make sure that the secondary latch keeps the hood from opening
when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently.
Lamps
Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim. Clean the headlamps on a regular basis.
—
Item
Reference page
Warning lamps and
chimes
Make sure that all warning lamps and chimes are operating properly.
—
Windshield wiper and
washer
Check that the wipers and washer operate properly and that the wipers do not
streak.
—
Windshield defroster
Check that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner.
—
Steering wheel
Check that it has the specified play. Be sure to check for changes in the steering
condition, such as excessive play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)
—
Seats
Check seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every
position. Check that the head restrains move up and down smoothly and that
the locks (if equipped) hold securely in all latched positions. Check that the
latches lock securely for folding-down rear seatbacks.
—
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.
Accelerator pedal
Check 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.
—
Brakes
Check that the brake does not pull the vehicle to one side when applied.

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).
Brake pedal and
booster
Check 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 the floor mats away from the pedal.
Parking brake
Check that the pedal 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.
CVT P (Park) position
mechanism
On a fairly steep hill check that the vehicle is held securely with the selector
lever in the P (Park) position without applying any brakes.

Item
Reference page
Item
Reference page
Windshield washer
fluid
Check that there is adequate fluid in the tank.
—
Engine coolant level
Check the coolant level when the engine is cold.
Radiator and hoses
Check the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation,
deterioration or loose connections.
—
Brake fluid level
Make sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir.
Battery
Check 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 belts
Make sure that no belt is frayed, worn, cracked or oily.
Engine oil level
Check the level on the dipstick after parking the vehicle on a level spot and turn-
ing off the engine.
Power steering fluid
level and lines
Check the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.
Exhaust system
Make 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.
Underbody
The 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 sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust system. 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 accumulate.
—
Fluid leaks
Check 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
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary.
NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, inspect CVT fluid deterioration with CON-
SULT-II every 60,000 miles (96,000 km), then change CVT fluid NS-2 if necessary. (Refer to
CVT-68, "Check CVT Fluid Deterioration
.) And if CONSULT-II is not available, change (not just inspect) CVT fluid NS-2 every 60,000 miles (96,000 km). Using transmis-
sion fluid other than Genuine Nissan CVT Fluid NS-2 will damage the CVT transmission, which is not covered by the NISSAN
new vehicle limited warranty.
(2) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every
30,000 miles (48,000) or 24 months.
(3) Refer to “Tire rotation” under the “General maintenance” heading earlier in this section.

Anti-Freeze Coolant Mixture Ratio
ALS000DD
The engine cooling system is filled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only Genuine
Nissan Anti-freeze coolant or equivalent with the proper mix-
ture ratio of 50% anti-freeze and 50% demineralized water/dis-
tilled water.
Other types of coolant solutions may damage your cooling sys-
tem.

Checking Drive Belts
ALS000DE
WARNING:
Be sure to perform when the engine is stopped.
1.
Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2.
Inspect drive belt deflection or tension at a point on the belt mid-
way between pulleys.
●
Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.
●
Measure belt tension with tension gauge (BT3373-F or equiv-
alent) at points marked shown in the figure.
●
When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point.
●
Adjust if belt deflection exceeds the limit or if belt tension is
not within specifications.
CAUTION:
●
When checking belt deflection or tension immediately after installation, first adjust it to the speci-
fied value. Then, after turning the crankshaft two turns or more, re-adjust to the specified value to
avoid variation in deflection between pulleys.
●
Tighten idler pulley lock nut by hand and measure deflec-
tion or tension without looseness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on the belt.
Tension Adjustment
ALS000DF
CAUTION:
●
When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.
