BASIC INSPECTIONBATTERYHow to Handle Battery INFOID:0000000003926418
CAUTION:• If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.• After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.• Never add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging a battery.• The battery surface (particularly its top) should always be kept
clean and dry.• The terminal connections should be clean and tight.• At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance” and“maintenance-free”.
• When the vehicle is not going to be used over a long period oftime, disconnect the battery cable from the negative terminal. (Ifthe vehicle has an extended storage switch, turn it off.)
• Check the charge condition of the battery.Periodically check the specific gravity of the electrolyte. Keep aclose check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVELWARNING:Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

< BASIC INSPECTION >• Remove the cell plug using a suitable tool.• Add distilled water up to the MAX level.
SulphationA battery will be completely discharged if it is left unattendedfor a long time and the specific gravity will become less than1.100. This may result in sulphation on the cell plates.To determine if a battery has been “sulphated”, note its voltageand current when charging it. As shown in the figure, less cur-rent and higher voltage are observed in the initial stage ofcharging sulphated batteries.A sulphated battery may sometimes be brought back into ser-vice by means of a long, slow charge, 12 hours or more, fol-lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK1. Read hydrometer and thermometer indications at eye level.2. Use the chart below to correct your hydrometer reading accord-
ing to electrolyte temperature.

CHARGING THE BATTERYCAUTION:• 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
Do not charge at more than 50 ampere rate.NOTE:The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi-cates that the voltage of the battery is increasing normally as the state of charge improves. The charging ampsindicated above refer to initial charge rate.• If, after charging, the specific gravity of any two cells varies more than 0.050, the battery should be replaced.

TROUBLE DIAGNOSIS WITH BATTERY SERVICE CENTERFor 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.

< COMPONENT DIAGNOSIS >Fuse INFOID:0000000003926436
• If fuse is blown, be sure to eliminate cause of malfunction beforeinstalling new fuse.
• Use fuse of specified rating. Never use fuse of more than specifiedrating.
• Do not partially install fuse; always insert it into fuse holder prop-erly.
• Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is notused for a long period of time.
Fusible Link INFOID:0000000003926437
A melted fusible link can be detected either by visual inspection or byfeeling with finger tip. If its condition is questionable, use circuittester or test lamp.
CAUTION:• If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted. Insuch a case, carefully check and eliminate cause of malfunc-tion.
• Never wrap outside of fusible link with vinyl tape. Important:Never let fusible link touch any other wiring harness, vinyl orrubber parts.
Circuit Breaker INFOID:0000000003926438
The PTC thermistor generates heat in response to current flow. Thetemperature (and resistance) of the thermistor element varies withcurrent flow. Excessive current flow will cause the element's temper-ature to rise. When the temperature reaches a specified level, theelectrical resistance will rise sharply to control the circuit current.Reduced current flow will cause the element to cool. Resistance fallsaccordingly and normal circuit current flow is allowed to resume.

PRECAUTIONPRECAUTIONSPrecaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000004114425
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used alongwith a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certaintypes of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRSsystem uses the seat belt switches to determine the front air bag deployment, and may only deploy one frontair bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.Information necessary to service the system safely is included in the “SRS AIRBAG” and “SEAT BELT” of thisService Manual.WARNING:• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed byan authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personalinjury caused by unintentional activation of the system. For removal of Spiral Cable and Air BagModule, see the “SRS AIRBAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harnessconnectors.
Precaution for Battery Service INFOID:0000000004114426
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-ence between the window edge and the vehicle when the door is opened/closed. During normal operation, thewindow slightly raises and lowers automatically to prevent any window to vehicle interference. The automaticwindow function will not work with the battery disconnected.
Precaution for Procedure without Cowl Top Cover INFOID:0000000004114427
When performing the procedure after removing cowl top cover, coverthe lower end of windshield with urethane, etc.
