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. —
Tire rotation Tires should be rotated every 12,000 km (7,500 miles). MA-31
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
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
,
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
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 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. MA-35

NOTE:
This item is displayed, but cannot be tested.
Auto Active TestINFOID:0000000001328875
DESCRIPTION
In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to the
following systems:
 Rear window defogger
 Front wipers
 Parking, license plate, side marker and tail lamps
 Front fog lamps
 Headlamps (Hi, Lo)
 A/C compressor (magnetic clutch)
 Cooling fan
OPERATION PROCEDURE
1. Close hood and front door (passenger side), and then lift wiper arms away from windshield (to prevent
glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON, and within 20 seconds, pre ss drivers door switch 10 times (close other doors).
Then turn ignition switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chir ps once oil pressure warning lamp starts blinking.
6. After a series of operations is repeated three times, auto active test is completed. NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Be sure to inspect BL-38, "
Check Door Switch" when the auto active t est cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following eight steps are repeated three times.
Front wiper (HI, LO) operation FRONT WIPER With a certain operation (Off, Hi, Lo),
the front wiper relay (Lo, Hi) can
be operated.
Cooling fan operation MOTOR FAN With a certain operation (1, 2, 3, 4), the cooling fan can be operated.

BATTERY
CHARGING THE BATTERY
CAUTION:
 Never “quick charge” a fully discharged battery.
 Keep the battery away from open flame while it is being charged.
 When connecting the charger, connect the leads first, then turn on the charger. Never turn on the
charger first, as this may cause a spark.
 If battery electrolyte temperature rises above 55 °C (131 °F), stop charging. Always charge battery at a
temperature below 55 °C (131 °F).
Charging Rates
Never charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automat ically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing norma lly as the state of charge improves. The charging amps
indicated above refer to initial charge rate.
 If, after charging, the specific gravity of any two ce lls varies more than 0.050, the battery should be replaced.
Trouble Diagnosis with Battery Service CenterINFOID:0000000001328244
For battery testing, use Battery Service Center (J-48087) . For details and operating instructions, refer to Tech-
nical Service Bulletin and/or Battery Service Center User Guide.
