2020 NISSAN ALTIMA air condition

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 pre-
vent damage to or accidental inflation
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 in-
jury. For example, do not change the
driver or passenger knee bolster or
install additional trim material
around the knee air bag.

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.

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 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, knee air bag or
pretensioner systems may not operate
properly. They must be checked and re-
paired. It is recommended 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,
have your vehicle checked as soon as
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 ba-
sis. As a reminder, unless it is damaged, the
supplemental air bag warning light re-
mains 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 ve-
hicle. 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.

CAUTION
When engine speed approaches the red
zone, reduce engine speed. Operating
the engine in the red zone may cause
serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range
1when
the gauge needle points within the zone
shown in the illustration.
The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
CAUTION
If the gauge indicates coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
temperature. If the gauge is over the
normal range, stop the vehicle as soon
as safely possible. If the engine is over-
heated, continued operation of the ve-
hicle may seriously damage the engine.

CVT (AT) Malfunction Service now (if so
equipped)
This warning illuminates when there is a
problem with the CVT system. If this warn-
ing comes on, have the system checked. It
is recommended that you visit a NISSAN
dealer for this service.
Service CVT (AT) Power reduced (if so
equipped)
This transmission has a high fluid tem-
perature protection mode. If the fluid tem-
perature becomes too high (for example,
climbing steep grades in high tempera-
tures with heavy loads, such as when tow-
ing a trailer), engine power and, under
some conditions, vehicle speed will be de-
creased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed
may be reduced.WARNING
When the high fluid temperature pro-
tection mode operation occurs, vehicle
speed may be gradually reduced. The
reduced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful when
driving. If necessary, pull to the side of
the road at a safe place and allow the
transmission to return to normal op-
eration; or have it repaired if necessary.
Unavailable: High Camera Temperature
(if so equipped)
This message appears when the camera
detects an interior temperature of more
than 104°F (40°C). For additional informa-
tion, refer to “Traffic Sign Recognition (TSR)”
in the “Starting and driving” section of this
manual. Your vehicle may have two types of security
systems:
∙ Vehicle security system
∙ NISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual
and audible alarm signals if someone
opens the doors or trunk when the system
is armed. It is not, however, a motion detec-
tion type system that activates when a ve-
hicle is moved or when a vibration occurs.
