NISSAN ALTIMA 2020 Owner´s Manual

∙ It is recommended that you visit aNISSAN dealer for work on and around
the knee air bag. It is also recom-
mended that you visit a NISSAN dealer
for installation of electrical equip-
ment. The SRS wiring harnesses*
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the knee air
bag system.
*The SRS wiring harness or connectors
are yellow or orange for easy identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the knee air
bag system and guide the buyer to the
appropriate sections in this manual.Seat belt with pretensioner(s)
(front and rear outboard seats)
WARNING
∙ The pretensioner(s) cannot be reused af ter activation. They must be re-
placed together with the retractor
and buckle as a unit.
∙ If the vehicle becomes involved in a collision but pretensioner(s) are not
activated, be sure to have the preten-
sioner system checked and, if neces-
sary, replaced. It is recommended that
you visit a NISSAN dealer for this
service.
∙ No unauthorized changes should be made to any components or wiring of
the pretensioner system. This is to
prevent damage to or accidental acti-
vation of the pretensioner(s). Tamper-
ing with the pretensioner system may
result in serious personal injury. ∙ It is recommended that you visit a
NISSAN 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 and rear out-
board seat occupants.
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.
1-66Safety—Seats, seat belts and supplemental restraint system

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.
The supplemental air bag warning
light
is used to indicate malfunctions
in the pretensioner system. For additional
information, refer to "Supplemental air bag
warning light" in this section. If the opera-
tion of the supplemental air bag warning
light indicates there is a malfunction, have
the system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s
Manual.

checked to verif y it is still functioning
correctly. It is recommended that you
visit a NISSAN dealer for this service.
The OCS should be checked even if no
air bags deploy as a result of the im-
pact. Failure to verif y proper OCS
function may result in an improper air
bag deployment resulting in injury or
death.
