SEAT BELT RETRACTOR ON-VEHICLE INSPECTION
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)

NOTE:
All seat belt retractors are of the Emergency Locking Retractors (ELR) type. In an emergency (sudden stop)
the retractor will lock and prevent the webbing from extending any further. All 3-point type seat belt retractors
except the driver's seat belt also have an Automatic Locking Retractors (ALR) mode. The ALR mode (also
called child restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt
is fully extended. When the webbing is then retracted partially, the ALR mode automatically locks the seat belt
in a specific position so the webbing cannot be extended any further. To cancel the ALR mode, allow the seat
belt to fully wind back into the retractor.
Check the seat belt retractors using the following test(s) to determine if a retractor assembly is operating prop-
erly.

ELR Function Stationary Inspection

Grasp the shoulder webbing and pull forward quickly. The retractor should lock and prevent the belt from
extending further.

ALR Function Stationary Inspection

Pull out entire length of seat belt from retractor until a click is heard.

Retract the webbing partially. A clicking noise should be heard as the webbing retracts indicating that the
retractor is in the Automatic Locking Retractor (ALR) mode.

Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If
necessary replace the retractor assembly.

Allow the entire length of the webbing to retract to cancel the automatic locking mode.

ELR Function Moving Inspection

WARNING:

Perform the following test in a safe, open area clear of other vehicles and obstructions (for example, a
large, empty parking lot). Road surface must be paved and dry. DO NOT perform the following test on
wet or gravel roads or on public streets and highways. This could result in an accident and serious
personal injury. The driver and passenger must be prepared to brace themselves in the event the
retractor does not lock.
1.

Fasten driver's seat belt. Buckle a passenger into the seat for the belt that is to be tested.

Proceed to the designated safe area.

Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of a pending sudden stop.
The driver and passenger must be prepared to brace themselves in the event the retractor does not lock.
Apply brakes firmly and make a very hard stop.

During stop, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock, per-
form the retractor off-vehicle inspection.

PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”

NKS001M8

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air 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 and SB section of this Service Man-
ual.

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 per-
formed by an authorized NISSAN/INFINITI dealer.

●

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

●

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

How to Handle Battery

NKS001MC

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.

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 of
time, disconnect the battery cable from the negative terminal.

●

Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.

CHECKING ELECTROLYTE LEVEL

WARNING:

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.

●

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 will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging 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 CHECK

Read hydrometer and thermometer indications at eye level.

Use the chart below to correct your hydrometer reading accord-
ing to electrolyte temperature.

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 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 amps
indicated 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/Starting/Charging System Tester (Battery)

NKS001MD

CAUTION:

When working with batteries, always wear appropriate eye protection.

NOTE:

●

To ensure a complete and thorough diagnosis, the battery, starter and alternator test segments must be
done as a set from start to finish.

●

If battery surface charge is detected while testing, the tester will prompt you to turn on the headlamps to
remove the surface charge.

●

If necessary, the tester will prompt you to determine if the battery temperature is above or below 0

C (32

F). Choose the appropriate selection by pressing the up or down arrow button, then press “ENTER” to

make the selection.
