2023 NISSAN SENTRA air suspension

•The child restraint is not properly installed,
as outlined in “Child restraints” (P. 1-23).
• An object weighing over 9.1 lbs. (4 kg) hanging on the seat or placed in the seat-
back pocket (if so equipped).
• A child restraint or other object pressing against the rear of the seatback.
• A rear passenger pushing or pulling on the back of the front passenger seat.
• Forcing the front seat or seatback against an object on the seat or floor be-
hind it.
• An object placed under the front passen- ger seat.
• An object placed between the seat cush- ion and center console.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions. Re-
start the vehicle and wait 1 minute.
NOTE:
A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially. If the light is still OFF af ter this, the small
adult, child or child restraint should be re-
positioned in the rear seat and the vehicle
should be checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
3. If the light is OFF with no front passenger
and no objects on the front passenger
seat, the vehicle should be checked. It is
recommended that you visit a NISSAN
dealer as soon as possible.
Other supplemental front-impact air
bag precautions
WARNING
• Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
• Immediately af ter inflation, several
front 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 supplemental air bag system. This
is to prevent accidental inflation of the
supplemental air bag or damage to
the supplemental air bag system.
• Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or front end
structure. This could affect proper
operation of the front air bag system.
• Tampering with the front air bag sys-
tem may result in serious personal
injury. Tampering includes changes
to the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad
and above the instrument panel or
by installing additional trim material
around the air bag system.
• Removing or modif ying the front
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury.
Safety-Seats, seat belts and supplemental restraint system1-59

•Do not make unauthorized changes
to your vehicle's electrical system,
suspension system or side panel.
This could affect proper operation of
the side air bag and curtain air bag
systems.
• Tampering with the side air bag sys-
tem may result in serious personal
injury. For example, do not change
the front and rear seats by placing
material near the seatbacks or by in-
stalling additional trim material,
such as seat covers, around the side
air bag.
•
It is recommended that you visit a
NISSAN dealer for work on and around
the side air bag and curtain air bag. It is
also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the side air bag
or curtain air bag system.
* The SRS wiring harness connectors are
yellow and orange for easy identification.
When selling your vehicle, we request that
you inform the buyer about the side air bag
and curtain air bag systems and guide the
buyer to the appropriate sections in this
Owner's Manual.
Driver and front passenger
supplemental knee air bag
The knee air bag is located in the knee
bolster, on the driver’s and front passen-
ger’s side. All of the information, cautions
and warnings in this manual apply and
must be followed. The knee air bag is de-
signed to inflate in higher severity frontal
collisions, although it may inflate if the
forces in another type of collision are simi-
lar to those of a higher severity frontal im-
pact. It may not inflate in certain collisions.
LRS3270
Driver’s side
1-62Safety-Seats, seat belts and supplemental restraint system

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.
