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.
SEAT BELT RETRACTOR OFF-VEHICLE CHECK
1. Remove the seat belt retractor.
Remove the rear seat belt assembly, refer to SB-10, "
SEAT BELT RETRACTOR : Removal and Installa-
tion".

twisting the retractor assembly as shown in the illustration.
 The webbing can be pulled out when the angle (A) is 15
degrees or more.
 The webbing cannot be pulled out when the angle (B) is 27
degrees or more.
3. If the seat belt assembly dose not operate normally, replace the seat belt assembly.

NISSAN/INFINITI 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. Not
doing 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-ten-
sioners 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 is in use at the time of a collision (except for minor collisions and the belts, retractors and buck-
les show no damage and continue to operate properly).
 The seat belt is damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.)
 The seat belt attaching point is damaged in an accident. Inspect the seat belt attaching area for damage or
distortion and repair if necessary before installing a new seat belt assembly.
 Anchor bolts are deformed or worn out.
 The seat belt pre-tensioner must 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 that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
2. Repeat step above as necessary to check the other seat belts.
