PRECAUTIONS
Revision: June 20062007 Versa
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EHS001TO
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.
WAR NIN G:

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 ServiceEHS001TP
CAUTION:

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

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-21, "
SRS Operation Check"
.

Do not disassemble buckle or seat belt assembly.

Do not reuse seat belt anchor bolts after removal. Replace with new ones.

Replace anchor bolts if they are deformed or worn out.

Never 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
WAR NIN G:

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
collision 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
collision should also be replaced if either damage or improper operation is noted. Seat belt pre-
tensioner 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 seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.

AFTER A COLLISION
WAR NIN G:
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-tensioner
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, etc.)

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 seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal colli-
sion in which the air bags are deployed.
PRELIMINARY CHECKS
1. Check the seat belt warning lamp/chime for proper operation as follows:
a. Switch ignition ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime should
sound for about seven seconds.
b. Fasten driver's seat belt. The seat belt warning lamp should go out and the chime (if sounding) should
stop.
2. If the air bag warning lamp is blinking, conduct self-diagnosis using CONSULT-II, and air bag warning
lamp. Refer to SRS-21, "
SRS Operation Check" .
3. Check that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
4. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Ensure guide swivels
freely and that webbing lays flat and does not bind in guide. Ensure height adjuster operates properly and
holds securely.
5. Check retractor operation:
a. Fully extend the seat belt webbing and check for twists, tears or other damage.
b. Allow the seat belt to retract. Make sure that webbing returns smoothly and completely into the retractor. If
the seat belt does not return smoothly, wipe the inside of the loops with a clean paper cloth. Dirt build-up
in the loops of the upper anchors can cause the seat belts to retract slowly.
c. Fasten the seat belt. Check the seat belt returns smoothly and completely to the retractor. If the webbing
does not return smoothly, the cause may be an accumulation of dust or dirt. Use the “SEAT BELT TAPE
SET” and perform the following steps.
Inspect the front seat belt though-anchor
1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
2. Use a clip or other device to attach the seat belt at the center pillar webbing opening.
3. Pass a thin wire though the D-ring anchor webbing opening. Hold both ends of the wire and pull taut
while moving it up and down several times along the webbing opening surface to remove matter stuck
there.
4. Any dirt that cannot be removed with the wire can be removed by cleaning the opening with a clean
cloth.
5. Apply tape at the point where the webbing contacts the though-anchor webbing opening.
NOTE:
Apply the tape so that there is no looseness or wrinkling.
6. Remove the clip attaching the seat belt and check that the webbing returns smoothly.
6. Repeat steps above as necessary to check the other seat belts.

1. Turn off all loads on the vehicle electrical system. Clean or repair
as necessary.
2. Visually inspect the battery, battery terminals and cable ends
with ignition switch in “OFF” position.
NOTE:
The contact surface between the battery terminals, cable ends
and tester leads must be clean for a valid test. A poor connec-
tion will prevent testing and a “CHECK CONNECTION” mes-
sage will appear during the test procedures. If this occurs, clean
the battery post and terminals, reconnect them and restart the
test.
3. Connect the red tester lead clamp to the positive battery termi-
nal, and the black to the negative terminal.
4. The tester will turn on automatically. Using the arrow keys,
select “IN-VEHICLE” on the tester and then press the “ENTER”
key.
5. Locate the battery type and rating stamped or written on the top
case of the battery to be tested.
NOTE:
The battery rating will be either of the following:

CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)

JIS: Japanese Industrial Standard.
When using the Battery Tester use the CCA rating only.

The tester requires the CCA rating for the battery be entered
exactly as it is written or stamped on the battery.

(U.S. market) Refer to the latest "Battery Testing" Technical
Service Bulletin (TSB) for a chart which contains these ratings
listed by vehicle.

You must not use the JIS rating.
6. Using the arrow and “ENTER” keys alternately, select the battery type and rating.
NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Only use CCA.
7. Press “ENTER” to begin the test. Diagnosis results are dis-
played on the tester. Refer to SC-8, "
