Precautions
SUPPLEMENTAL RESTRAINT SYSTEM (SRS) ªAIR BAGº AND ªSEAT BELT
PRE-TENSIONERº
NBRS0001The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS composition which is available to INFINITI QX4 is as follows:
IFor a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt
pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
IFor a side collision
The Supplemental Restraint System consists of side air bag module (located in the outer side of front seat),
satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness,
warning lamp (one of components of air bags for a frontal collision).
WARNING:
ITo 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 performed
by an authorized INFINITI dealer.
IImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
IDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
PRECAUTION FOR SEAT BELT SERVICENBRS0002CAUTION:
IBefore removing the seat belt pre-tensioner assembly, turn the ignition switch off, disconnect both
battery cables and wait at least 3 minutes.
IDo not use electrical test equipment for seat belt pre-tensioner connector.
IAfter replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to ªSRS Operation Checkº (RS-38) for details.
IDo not use disassemble buckle or seat belt assembly.
IReplace anchor bolts if they are deformed or worn out.
INever oil tongue and buckle.
IIf any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.
IIf webbing is cut, frayed, or damaged, replace seat belt assembly.
IWhen replacing seat belt assembly, use a genuine seat belt assembly.
After A CollisionNBRS0002S01WARNING:
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 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 if:
IThe 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).
IThe seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.)
IThe seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for dam-
age or distortion and repair as necessary before installing a new seat belt assembly.
IAnchor bolts are deformed or worn out.
IThe 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.

IThe seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in

PRELIMINARY CHECKSNBRS0029S021. 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 ªSRS Operation Checkº, RS-38.
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 swiv-
els freely and that belt 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. Ensure that belt returns smoothly and completely into the retractor. If the seat
belt does not returns smoothly, wipe the inside of the loops with a clean paper cloth etc. because dirt built
up in the loops of the upper anchors can cause the seat belts to retractor slowly.
SRS353
c. Fasten the seat belt. Pull firmly on belt and buckle to ensure belt remains latched. Unfasten seat belt.
Ensure belt releases freely and buckle button returns to original position.
6. For center (non-retractable) seat belts, check that the seat belt are accessible. Check seat belt webbing
for twists, tears or other damage. Fasten the seat belt. Pull firmly on belt and buckle to ensure belt remains
latched. Unfasten seat belts. Ensure belt releases freely and buckle button returns to original position.
7. Repeat steps above as necessary to check the other seat belts.
