AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attached hardware after any collision.
NISSAN/INFINITI recommends that all seat belt assemblies in use during a collision be replaced
unless the collision is minor and the belts show no damage and continue to operate properly. Not
doing so could result in serious personal injury in an accident. Seat belt assemblies not in use during
a collision must also be replaced if either damage or improper operation is noted. Seat belt pre-ten-
sioners must 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-tensioners should be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.
PRELIMINARY CHECKS
1. Check the seat belt warning lamp/chime for proper operation as follows:
a. Turn ignition switch ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime
should sound for about six seconds.
b. Fasten driver seat belt. The seat belt warning lamp should turn off and the chime (if sounding) should
stop.
2. If the air bag warning lamp is blinking, conduct self-diagnosis with CONSULT-III and air bag warning lamp.
Refer to SRC-10, "
Diagnosis Description".
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. Ensure 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. Because dirt
build-up in the loops of the upper anchors can cause the seat belts to retract slowly.
c. Fasten the seat belt. Check that 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 through-anchor
1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
2. Fix the seat belt at the center pillar webbing opening with a clip or other device.
3. Pass a thin wire through the through-anchor webbing opening. Hold both ends of the wire and pull it
tauntly while moving it up and down several times along the webbing opening surface to remove dirt
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 through-anchor webbing opening.
NOTE:
Apply the tape so that there is no looseness or wrinkling.

SEAT BELT RETRACTOR ON-VEHICLE CHECK
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are 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 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 with the following test(s) to determine if a retractor assembly is operating prop-
erly.
ELR Function Stationary Check
Grasp the shoulder webbing and pull forward quickly. The retractor should lock and prevent the belt from
extending further.
ALR Function Stationary Check
1. Pull out the entire length of seat belt from retractor until a click is heard.
2. Retract the webbing partially. A clicking noise should be heard as the webbing retracts indicating that the
retractor is in the Automatic Locking Retractors (ALR) mode.
3. Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If
NG, replace the retractor assembly.
4. Allow the entire length of the webbing to retract to cancel the automatic locking mode.
ELR Function Moving Check
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. Never 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 that the
retractor does not lock.
1. Fasten driver seat belt. Buckle a passenger into the seat for the belt that is to be tested.
2. Proceed to the designated safe area.
3. Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of a pending sudden stop
and the driver and passenger must be prepared to brace themselves in the event that the retractor does
not lock, apply brakes firmly and make a very hard stop.
During stopping, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock,
perform the retractor off-vehicle check.

< FUNCTION DIAGNOSIS >[INTELLIGENT KEY SYSTEM]
INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
4. BCM transmits the steering lock unlock signal to steering lock unit and IPDM E/R if the verification results
are OK.
5. IPDM E/R turns the steering lock relay ON and supplies power to the steering lock unit.
6. Release of the steering lock.
7. BCM transmits the power supply stop signal to IPDM E/R when it confirms that the steering lock is in the
unlock condition.
8. IPDM E/R turns the steering lock relay OFF and stops power supply to the steering lock unit.
9. BCM turns ACC relay ON and transmits the ignition power supply ON signal to IPDM E/R.
10. IPDM E/R turns the ignition relay ON and starts the ignition power supply.
11. BCM confirms that the shift position is P or N.
12. BCM transmits the starter request signal via CAN communication to IPDM E/R and turns the starter relay
in IPDM E/R ON if BCM judges that the engine start condition is satisfied.
13. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
14. Battery power is supplied through the starter relay and the starter control relay to operate the starter motor
and to start the cranking.
CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp in the combina-
tion meter illuminates. At that time, the engine cannot be started.
15. When BCM receives feedback signal from ECM acknowledging the engine has been initiated, the BCM
transmits a stop signal to IPDM E/R and stops the cranking by turning OFF the starter motor relay. (If the
engine initiating has failed, the cranking will stop automatically within 5 seconds.)
CAUTION:
When the Intelligent Key is carried outside of the vehicle (inside key antenna detection area) with
the power supply in the ACC or ON position, even if the engine start condition* is satisfied, the
engine cannot be started.
*: For the engine start condition, refer to “PUSH-BUTTON IGNITION SWITCH OPERATION PROCEDURE”.
OPERATION RANGE
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine might not start
when Intelligent Key is on instrument panel or in glove box.
OPERATION WHEN KEY SLOT IS USED
When the Intelligent Key battery is discharged, it performs the NVIS (NATS) ID verification between the inte-
grated transponder and BCM by inserting the Intelligent Key into the key slot, and then the engine can be
started.
For details relating to starting the engine using key slot, refer to SEC-14, "
