6. Remove the seat belt fixing, and confirm that webbing smoothly retracts.
c. Insert the seat belt into the buckle and confirm seat belt is firmly secured.
d. Remove the seat belt from buckle. Release the seat belt and confirm webbing and tongue are placed cor-
rectly.
5. Seat belt retractor unit inspection
a. Remove seat belt retractor.
b. As shown in the figure, without twisting retractor, recline the seat belt retractor at the position in which
retractor is mounted on the vehicle body. Slowly pull out the webbing.
Webbing is able to pull out when reclining 15 degrees or less.
Webbing is not able to pull out when reclining 35 degrees or more.
If it does not operate normally, replace seat belt assembly.
SEAT BELT WITH ELR INSPECTION
Seat Belt with ELR
ELR is a system which locks retractor in emergency cases such as sudden braking so that the webbing is
not pulled out any further.
There are 2 inspections: static and dynamic. Use the following procedures to check retractor for normal
operation.
ELR Static Inspection
Make sure that retractor locks and webbing stops immediately when quickly pulling webbing forward.
ELR Dynamic Inspection
WARNING:
The following tests should be performed in a safe, open place free of traffic and obstacles.
The tests should be performed on a dry paved road. Do not attempt the tests on wet or unpaved
road, open road, or highway. (This may cause an accident or personal injury.)
Driver and passenger assume retractor will not lock and prepare themselves accordingly.
1. Tighten driver and passenger seat belts.
2. Drive at approx. 16 km/h.
3. Notify passenger of a sudden stop. Driver and passenger prepare themselves for the possibility of retrac-
tor not locking. Then, driver fully depresses the brake pedal to stop suddenly.
4. While car stops, confirm if retractor is locked and webbing is not pulled out any more. Check for only
retractor part if it is not locked.

PRECAUTIONS
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS001M8
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. Information necessary to service the system safely is included in the SRS and SB 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 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 BKS001MB
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 of
time, disconnect the battery cable from the negative 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 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
1. Read hydrometer and thermometer indications at eye level.
2. Convert into specific gravity at 20°C (68°F).
Example:
When electrolyte temperature is 35°C (95°F) and specific gravity
of electrolyte is 1.230, converted specific gravity at 20°C (68°F)
is 1.240.
When electrolyte temperature is 0°C (32°F) and specific gravity
of electrolyte is 1.210, converted specific gravity at 20°C (68°F)
is 1.196.
