GENERAL MAINTENANCE
Explanation of Gene ral MaintenanceINFOID:0000000001328893
General maintenance includes those items which shoul d 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.
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. —

Wheel alignment and
balanceIf 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

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

held securely on a fairly steep hill when only the parking brake is applied. PB-3
Automatic transmis-
sion "Park" mecha-
nismCheck 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
selector lever in the P (Park) position without applying any brakes.

Windshield washer
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 BeltsINFOID:0000000001328900
WARNING:
Be sure to perform when 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 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 deflect ion or the tension immedi-
ately after installation, first ad just it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust
to the specified value to avo id 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.
