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 they can have their INFINITI dealers do them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
ItemReference page
TiresCheck the pressure with a gauge periodically when at a service station,
including the spare, and adjust to the specified pressure if necessary. Check
carefully for damage, cuts or excessive wear.Ð
Wheel nutsWhen checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.Ð
Tire rotationTires should be rotated every 12,000 km (7,500 miles). MA-24
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
alignment. If the steering wheel or seat vibrates at normal highway speeds,
wheel balancing may be needed.MA-24, SU-6, ªFront
Wheel Alignmentº
Windshield wiper
bladesCheck for cracks or wear if they do not wipe properly. Ð
Doors and engine
hoodCheck 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. Lubri-
cate 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
lubrication frequently.MA-27
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.
ItemReference page
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check
headlamp aim.Ð
Warning lamps and
buzzers/chimesMake sure that all warning lamps and buzzers/chimes are operating properly. Ð
Windshield wiper
and washerCheck that the wipers and washer operate properly and that the wipers do
not streak.Ð
Windshield defrosterCheck that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioning.Ð
Steering wheelCheck 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)Ð
SeatsCheck 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.Ð
Seat beltsCheck 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-28, RS-7, ªSeat Belt
Inspectionº
BrakesCheck that the brake does not pull the vehicle to one side when applied. Ð

Trouble Diagnoses with
Battery/Starting/Charging System Tester
NBSC0020NOTE:
To ensure a complete and thorough diagnosis, the battery, starter
and alternator test segments must be done as a set from start to
finish.
SEL417X
1. Turn off all loads on the vehicle electrical system.
2. Perform battery and starting system test with Battery/Starting/
Charging system tester.
3. Press ªENTERº to begin the charging system test.
4. Start engine.
SEL418X
5. Press ªENTERº until ªLOADS OFF REV ENGINE 5 SECº is
displayed.
6. Raise and hold the engine speed at 1,500 to 2,000 rpm for
about 5 seconds, then return to the engine to idle.
Once the increase in engine rpm is detected, press ªENTERº
to continue.
NOTE:
IIf after 30 seconds an increase in engine idle speed is not
detected, ªRPM NOT DETECTEDº will display.
ISome engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect this
without any other action being taken. If this occurs, continue on
with the testing process. The final results will not be affected.
SEL419X
7. The tester now checks the engine at idle and performs the
DIODE/RIPPLE check.
8. When complete, the tester will prompt you to turn on the fol-
lowing electrical loads.
IHeater fun set to highest. Do not run the A/C or windshield
defroster.
IHeadlamp high beam
