PRECAUTIONS

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BHS0003P
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.
Precaution for Seat Belt ServiceBHS0003Q
CAUTION:

Before removing the front seat belt pre-tensioner assembly, turn the ignition switch off, discon-
nect both battery cables and wait at least 3 minutes.

Do not use electrical test equipment for front seat belt pre-tensioner connector.

After replacing or reinstalling front seat belt pre-tensioner assembly, or reconnecting front seat
belt pre-tensioner connector, check the system function. Refer to SRS-16, "
SRS Operation Check"
.

Activate front seat belt pre-tensioner assembly before disposing. Refer to SRS-48, "DISPOSAL OF
AIR BAG MODULE AND SEAT BELT PRE-TENSIONER" .

Do not use disassembled buckle or seat belt assembly.

Replace anchor bolts if they are deformed or worn out.

Do not oil tongue and buckle.

If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.

If webbing is cut, frayed, or damaged, replace seat belt assembly.

When replacing seat belt assembly, use a genuine NISSAN seat belt assembly.
AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the col-
lision was minor and the belts show no damage and continue to operate properly. Failure to do so
could result in serious personal injury in an accident. Seat belt assemblies not in use during a colli-
sion should also be replaced if either damage or improper operation is noted. Seat belt pre-tensioners
should be replaced even if the seat belts are not in use during a frontal collision in which the air bags
are deployed.
Replace any seat belt assembly (including anchor bolts) if:

The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).

The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide).

The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.

Anchor bolts are deformed or worn out.

The front seat belt pre-tensioners should be replaced even if the seat belts are not in use during the colli-
sion in which the air bags are deployed.

CAUTION:
Before removal or installation, be sure to turn ignition switch OFF and disconnect both battery cables,
then wait for at least 3 minutes.
REMOVAL OF RETRACTOR
1. Slide outer anchor cover upward. Remove anchor bolt.
2. Remove center pillar lower garnish and center pillar upper garnish. Refer to EI-38, "
Removal and Installa-
tion" .
3. Remove shoulder anchor mounting anchor nut.
4. Remove seat belt adjuster mounting bolt.
5. Disconnect seat belt pre-tensioner connector.
CAUTION:

For disconnecting pre-tensioner connector, insert a
screwdriver wrapped with tape into cutout, and raise lock
to disconnect connector.

Connect connector with lock raised, and push lock into
connector.

BATTERYPFP:AYBGL
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.
