NISSAN 2010 Sentra - Manual (Page 73)

Seat belts with pretensioners (front
seats)
WARNING
● The pretensioners cannot be reused af-
ter activation. They must be replaced
together with the retractor and buckle
as a unit.
● If the vehicle becomes involved in a
frontal collision but a pretensioner is
not activated, be sure to have the pre-
tensioner system checked and, if nec-
essary, replaced by your NISSAN
dealer.
● No unauthorized changes should be
made to any components or wiring of
the pretensioner system. This is to pre-
vent damage to or accidental activation
of the pretensioners. Tampering with
the pretensioner system may result in
serious personal injury.
● Work around and on the pretensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pretensioner system.
● If you need to dispose of a pretensioner
or scrap the vehicle, contact a NISSAN
dealer. Incorrect disposal procedures
could cause personal injury.
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 within 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. They
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.
