∙ It is recommended that you visit aNISSAN dealer for work on and around
the pretensioner system. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. Unauthorized electrical
test equipment and probing devices
should not be used on the preten-
sioner system.
∙ If you need to dispose of the preten- sioner(s) or scrap the vehicle, it is rec-
ommended that you visit a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause per-
sonal injury.
The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with the
seat belt retractor, the pretensioner(s) help
tighten the seat belt when the vehicle be-
comes involved in certain types of colli-
sions, helping to restrain front seat occu-
pants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt an-
chor affixed to the floor of the vehicle.
These seat belts are used the same way as
conventional seat belts. When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.
