2020 NISSAN SENTRA ignition

Vehicle damage (or lack of it) is not always
an indication of proper knee air bag opera-
tion.
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 posi-
tion.
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.

If any of the following conditions occur, the
front air bag, side air bag, curtain air bag
and pretensioner systems need servicing:
• The supplemental air bag warning lightremains on af ter approximately 7 sec-
onds.
• 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
and/or pretensioner systems will not
operate in an accident. To help avoid
injury to yourself or others, have your
vehicle checked as soon as possible. It
is recommended that you visit a
NISSAN dealer for this service.
NOTE:
In the event of a crash involving an air
bag deployment (side, front or both), the
vehicle’s hazard lamps (turn indicators)
will turn ON automatically.
Repair and replacement
procedure
The front air bags, side air bags, curtain air
bags and pretensioner(s) are designed to
inflate on a one-time-only basis. As a re-
minder, unless it is damaged, the supple-
mental air bag warning light remains illu-
minated af ter inflation has occurred. These
systems should be repaired and/or re-
placed as soon as possible. It is recom-
mended 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, pretensioner(s) and re-
lated parts should be pointed out to the
person performing the maintenance. The
ignition switch should always be placed in
the LOCK position when working under the
hood or inside the vehicle.
WARNING
• Once a front air bag, side air bag, or
curtain air bag has inflated, the air
bag module will not function again
and must be replaced. Additionally,
the activated pretensioner(s) must
also be replaced. The air bag module
and pretensioner(s) should be re-
placed. It is recommended that you
visit a NISSAN dealer for this service.
However, the air bag module and pre-
tensioner(s) cannot be repaired.
• The front air bag, side air bag, curtain
air bag systems and the preten-
sioner system should be inspected if
there is any damage to the front end
or side portion of the vehicle. It is rec-
ommended 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 visit a NISSAN
dealer. Incorrect disposal procedures
could cause personal injury.

value is calculated based on recent fuel
economy, the amount of fuel remaining in
the fuel tank, and the actual fuel consump-
tion. Changes in driving patterns or conditions
can cause the DTE value to vary. As a result,
the value displayed may differ from the ac-
tual distance that can be driven.
DTE display will change to “---” when the
fuel level in the tank is getting low, prior to
the fuel gauge reaching 0 (Empty).
NOTE:
• The DTE value af ter refill is estimated
based on recent fuel economy and
amount of fuel added.
• If a small amount of fuel is added, or the ignition is on during refueling, the
display may not be updated.
• Conditions that affect the fuel economy will also affect the estimated
DTE value (city/highway driving, idle
time, remote start time, terrain, sea-
sonal weather, added vehicle weight,
added deflectors, roof racks, etc.).
