NISSAN 2011 Altima - Manual (Page 75)

The pretensioner system activates in conjunction
with the front air bag system. Working with the
seat belt retractor, it helps tighten the seat belt
when the vehicle becomes involved in certain
types of collisions, helping to restrain front seat
occupants.
The pretensioner is encased with the seat belt
retractor. These seat belts are used the same way
as conventional seat belts.
When a pretensioner activates, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indicate a fire.
Care should be taken not to inhale it, as it may
cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
After pretensioner activation, load limiters allow
the seat belt to release webbing (if necessary) to
reduce forces against the chest.
If any abnormality occurs in the pretensioner sys-
tem,
the supplemental air bag warning
light will not come on, will flash intermit-
tently or will turn on for 7 seconds and remain on
after the ignition switch has been placed in the
ON or START position. In this case, the preten-
sioner system may not function properly. It must
be checked and repaired. Take your vehicle to the
nearest NISSAN dealer.
When selling your vehicle, we request that you
inform the buyer about the pretensioner system
and guide the buyer to the appropriate sections
in this Owner’s Manual.
