GENERAL MAINTENANCE

Explanation of General Maintenance

INFOID:0000000001328893

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 INFINITI 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.

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).

Transmitter compo-
nents in tire pressure
monitoring system
(TPMS)

Replace grommet seal, valve core and cap of the transmitter in TPMS every tire
replacement by reaching wear limit of tire.

WT-10

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.

MA-30

FSU-5

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.

MA-35

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 po-
sition. 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.

GENERAL MAINTENANCE

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).

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.

—

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.

fluid

Check that there is adequate fluid in the tank.

—

Engine coolant level

Check the coolant level when the engine is cold.

MA-12

MA-19

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, de-
terioration or loose connections.

—

Brake fluid level

Make sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir.

MA-32

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 re-
quire frequent checks of the battery fluid level.

SC-4

Engine drive belts

Make sure that no belt is frayed, worn, cracked or oily.

MA-11

MA-19

Engine oil level

Check the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine.

MA-15

MA-22

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.

MA-33

Exhaust system

Make sure there are no loose supports, cracks or holes. If the sound of the ex-
haust seems unusual or there is a smell of exhaust fumes, immediately locate
the trouble and correct it.

MA-26

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.

ENGINE MAINTENANCE (VQ35DE ENGINE)

Checking Drive Belts

INFOID:0000000001328900

WARNING:

Be sure to perform when engine is stopped.
1.

Inspect belts for cracks, fraying, wear and oil. If necessary, replace.

Inspect drive belt deflection or tension at a point on belt midway
between pulleys.

• Inspection should be done only when engine is cold, or over

30 minutes after engine is stopped.

• Measure the belt tension with belt tension gauge (Commercial

service tool: BT3373-F or equivalent) (A) at points marked
shown in the figure.

• When measuring the deflection, apply 98 N (10 kg, 22 lb) at

the marked point.

• Adjust if the belt deflection exceeds the limit or if the belt ten-

sion is not within specifications.

CAUTION:

• When checking the belt deflection or the tension immedi-

ately after installation, first adjust it to the specified value.
Then, after turning 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 the deflection or the tension without loose-

ness.

Belt Deflection and Tension

*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.

• When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-

cient adaptability with pulley grooves.

• When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-

ment”.

• When checking belt deflection or tension immediately after installation, first adjust it to the specified

value. Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid vari-
ation in deflection between pulleys.

• When installing belt, make sure that it is correctly engaged with pulley grooves.
• Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.
• Do not twist or bend belt excessively.
