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.

INSPECTION AFTER ACCIDENT
After a collision, inspect for damage or distortion of retractor, seat belt anchor, floor anchor, or shoulder
anchor. Nissan recommends replacement of all seat belt assemblies in the following cases because these
impairments may lead to personal injury.

After a collision

When installation point of seat belt assembly on vehicle is damaged.

When it does not operate normally.
INSPECTION FOR SEAT BELT RETRACTOR
1. Using seat belt warning lamp, make sure that it works normally.
NOTE:
When ignition is turned ON and driver seat belt is not in use, seat belt warning lamp is turned on. It is
turned off when driver seat belt is in use.
2. Check whether anchor bolts on seat belt retractor and buckle are securely tightened.
3. Check if seat belt shoulder anchor rotates freely and seat belt adjuster operates properly.
4. Retractor operation inspection
a. Pull out all webbing and check for twisting, cuts, or other damage.
b. Retract webbing. Check if the webbing is retracted smoothly and completely into the retractor. When web-
bing is not retracted smoothly due to dust or other reasons, perform the following procedure with “SEAT
BELT, TAPE SET”.
Inspection for Front Seat Belt Shoulder Anchor
1. Pull webbing out 50 cm or more.
2. Fix webbing near the belt exit with a clip.
3. Pass a thin wire into the through part of shoulder anchor and webbing. Remove the materials that are
stuck from the webbing by sliding the wire vertically along the surface of the webbing through part while
pulling both sides of wire tightly.
4. Clean the remaining dirt by cleaning the webbing through part with a clean cloth.
5. Apply tape to the shoulder anchor belt through part where webbing touches.
NOTE:
Be careful to apply tape with no wrinkling or looseness.

6. Remove the seat belt fixing, and confirm that webbing smoothly retracts.
c. Insert the seat belt into the buckle and confirm seat belt is firmly secured.
d. Remove the seat belt from buckle. Release the seat belt and confirm webbing and tongue are placed cor-
rectly.
5. Seat belt retractor unit inspection
a. Remove seat belt retractor.
b. As shown in the figure, without twisting retractor, recline the seat belt retractor at the position in which
retractor is mounted on the vehicle body. Slowly pull out the webbing.

Webbing is able to pull out when reclining 15 degrees or less.

Webbing is not able to pull out when reclining 35 degrees or more.
If it does not operate normally, replace seat belt assembly.
SEAT BELT WITH ELR INSPECTION
Seat Belt with ELR

ELR is a system which locks retractor in emergency cases such as sudden braking so that the webbing is
not pulled out any further.

There are 2 inspections: static and dynamic. Use the following procedures to check retractor for normal
operation.
ELR Static Inspection
Make sure that retractor locks and webbing stops immediately when quickly pulling webbing forward.
ELR Dynamic Inspection
WARNING:

The following tests should be performed in a safe, open place free of traffic and obstacles.

The tests should be performed on a dry paved road. Do not attempt the tests on wet or unpaved
road, open road, or highway. (This may cause an accident or personal injury.)

Driver and passenger assume retractor will not lock and prepare themselves accordingly.
1. Tighten driver and passenger seat belts.
2. Drive at approx. 16 km/h.
3. Notify passenger of a sudden stop. Driver and passenger prepare themselves for the possibility of retrac-
tor not locking. Then, driver fully depresses the brake pedal to stop suddenly.
4. While car stops, confirm if retractor is locked and webbing is not pulled out any more. Check for only
retractor part if it is not locked.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS001M8
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.
