PRECAUTIONS AND PREPARATION

Supplemental Restraint System (SRS) ‘‘AIR BAG’’

The Supplemental Restraint System ‘‘AIR BAG’’, used along with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel and in the instrument panel on the passenger side), a diagnosis sensor unit, a crash zone sensor, warning lamp, wiring harness and spiral cable. The vehicle is equipped with a passenger air bag deactivation switch. Because no rear seat exists where a rear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that a rear-facing child restraint can be used in the front passenger seat. The switch is located in the center of the instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is enabled and could inflate in a frontal collision. When the switch is turned to the OFF position, the passenger air bag is disabled and will not inflate in a frontal collision. A passenger air bag OFF indicator on the instrument panel lights up when the passenger air bag is switched OFF.The driver air bag always remains enabled and is not affected by the passenger air bag deactivation switch. Information necessary to service the system is included in the RS section of this Service 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 should be performed by an authorized NISSAN dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system.

●

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the harness connectors or on the complete harness, for easy identification.

●

The vehicle is equipped with a passenger air bag deactivation switch which can be operated by the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and will not inflate in a frontal collision. When the passenger air bag is switched ON, the passenger air bag is enabled and could inflate in a frontal collision. After SRS maintenance or repair, make sure the passenger air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for service.

Fusible Link

A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is questionable, use circuit tester or test lamp.

CAUTION:

●

If fusible link should melt, it is possible that critical circuit (power supply or large current carrying circuit) is shorted. In such a case, carefully check and eliminate cause of problem.

●

Never wrap outside of fusible link with vinyl tape. Impor-

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.

How to Handle Battery

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.

SEL711E

SEL712E

SEL459R

●

When the vehicle is not going to be used over a long period of time, disconnect the negative battery terminal. (If the 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 a close check on charge condition to prevent overdischarge.

CHECKING ELECTROLYTE LEVEL

WARNING:

Do not allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touching a battery, do not touch or rub youreyes until you have thoroughly washed your hands. If the acid contacts the eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention. Normally the battery does not require additional water. However, when the battery is used under severe conditions, adding distilled water may be necessary during the battery life.

SEL001K

SEL005Z

●

Remove the cell plug using a suitable tool.

●

Add distilled water up to the MAX level.

SULPHATION

A battery will be completely discharged if it is left unattended for a long time and the specific gravity becomes less than 1.100. This may result in sulphation on the cell plates. To determineif a battery has been‘‘sulphated’’, note its voltageand current when charging it. As shown in the figure, less current and higher voltage are observed in the initial stage of charging sulphated batteries. A sulphated battery may sometimes be brought back into service by means of a long, slow charge, 12 hours or more, followed by a battery capacity test.

SPECIFIC GRAVITY CHECK

1. Read hydrometer and thermometer indications at eye level.

SEL442D

CHARGING THE BATTERY

CAUTION:

●

Do not ‘‘quick charge’’ a fully discharged battery.

●

Keep the battery away from open flame while it is being charged.

●

When connecting the charger, connectthe leads first, then turn on the charger. Do not turn on the charger first, as this may cause a spark.

●

If battery electrolyte temperature rises above 60°C (140°F), stop charging. Always charge battery at a temperature below 60°C (140°F).

Charging rates

Amps Time

50 25 10 5

Do not charge at more than 50 ampere rate. Note: The ammeter reading on your battery charger will auto-

matically decrease as the battery charges. This indicates that the voltage of the battery is increasing normally 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 cells varies more than .050, the battery should be replaced.

●

After the battery is charged, always perform a capacity test to assure that the battery is serviceable.
