2023 NISSAN SENTRA Air condition

Vehicle damage (or lack of it) is not always an
indication of proper knee air bag operation.
When the knee air bag inflates, a fairly loud
noise may be heard, followed by release of
smoke. This smoke is not harmful and
does not indicate a fire. Care should be
taken not to inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.The knee air bag helps to cushion the im-
pact force on the knees of the driver and
passenger. It can help reduce serious inju-
ries. However, an inflating knee air bag may
cause abrasions or other injuries. The knee
air bag provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of
this, the force of the knee air bag inflating
can increase the risk of injury if the occu-
pant is too close to, or is against, this air bag
module during inflation. The knee air bag
will deflate quickly af ter the collision is over
OR the knee air bag will remain inflated for
a short time.
The knee air bag operates only when
the ignition switch is placed in the ON
position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
WARNING
• Do not place any objects between the
knee bolster and the driver’s or pas-
senger’s seat. Such objects may be-
come dangerous projectiles and
cause injury if a knee air bag inflates.
• Right af ter inflation, the knee air bag
system components will be hot. Do
not touch them; you may severely
burn yourself.
• No unauthorized changes should be
made to any components or wiring
of the knee air bag system. This is to
prevent damage to or accidental in-
flation of the knee air bag system.
• Do not make unauthorized changes
to your vehicle's electrical system or
suspension system. This could affect
proper operation of the knee air bag
system.
• Tampering with the knee air bag sys-
tem may result in serious personal
injury. For example, do not change
the driver or passenger knee bolster
or install additional trim material
around the knee air bag.

•It is recommended that you visit a
NISSAN dealer for work on and
around the knee air bag. It is also rec-
ommended that you visit a NISSAN
dealer for installation of electrical
equipment. The SRS wiring har-
nesses* should not be modified or
disconnected. Unauthorized electri-
cal test equipment and probing de-
vices should not be used on the knee
air bag system.
*The SRS wiring harness or connectors are
yellow or orange for easy identification.
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 re-
used af ter activation. They must be
replaced 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 ac-
tivation of the pretensioner(s). Tam-
pering 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 recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. Unauthorized elec-
trical test equipment and probing
devices should not be used on the
pretensioner 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.
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.

If any of the following conditions occur, the
front air bag, side air bag, curtain air bag,
knee air bag and pretensioner systems
need servicing:
•
The supplemental air bag warning light
remains on af ter approximately 7 seconds.
• The supplemental air bag warning light flashes intermittently.
• The supplemental air bag warning light does not come on at all.
Under these conditions, the front air bag,
side air bag, curtain air bag or pretensioner
systems may not operate properly. They
must be checked and repaired. It is recom-
mended that you visit a NISSAN dealer for
this service.
WARNING
If the supplemental air bag warning
light is on, it could mean that the front
air bag, side air bag, curtain air bag,
knee air bag and/or pretensioner sys-
tems will not operate in an accident. To
help avoid injury to yourself or others,

possible. It is recommended that you
visit a NISSAN dealer for this service.
Repair and replacement
procedure
The front air bags, side air bags, curtain air
bags, knee air bags and pretensioner(s)
are designed to inflate on a one-time-only
basis. As a reminder, unless it is damaged,
the supplemental air bag warning light
remains illuminated af ter inflation has oc-
curred. These systems should be repaired
and/or replaced as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, knee air bags, pretension-
er(s) and related parts should be pointed
out to the person performing the mainte-
nance. The ignition switch should always
be placed in the LOCK position when work-
ing under the hood or inside the vehicle.
WARNING
• Once a front air bag, side air bag, cur-
tain air bag or knee air bag has in-
flated, the air bag module will not
function again and must be replaced.
Additionally, the activated preten-
sioner(s) must also be replaced. The
air bag module and pretensioner(s)
should be replaced. It is recom-
mended that you visit a NISSAN
dealer for this service. However, the
air bag module and pretensioner(s)
cannot be repaired.
• The front air bag, side air bag, curtain
air bag, knee air bag systems and the
pretensioner system should be in-
spected if there is any damage to
the front end or side portion of the
vehicle. It is recommended that you
visit a NISSAN dealer for this service.
• If you need to dispose of the supple-
mental air bag or pretensioner sys-
tems or scrap the vehicle, it is recom-
mended that you contact a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause per-
sonal injury.
