2022 NISSAN ALTIMA coolant temperature

∙ When the climate system is in auto-matic operation and the engine coolant
temperature and outside air tempera-
ture are low, the air flow outlet may de-
fault to defroster mode for a maximum
of 2 minutes 30 seconds. This is not a
malfunction. Af ter the engine coolant
temperature warms up, the air flow out-
let will return to foot mode and opera-
tion will continue normally.
∙ When the outside and interior cabin temperatures are moderate to high, the
intake setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may oc-
cur when the previous climate setting
was turned off. This is not a malfunction.
Af ter the initial warm air is expelled, the
intake will return to automatic control,
the air flow outlet will return to previous
settings, and operation will continue
normally. To exit, press any climate con-
trol button.
∙ Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration. ∙ If you feel that the air flow mode you
have selected and the outlets the air is
coming out do not match, select
the

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A.
If the reservoir is empty, check the coolant
level in the radiator when the engine is
cold. If there is insufficient coolant in the
radiator, fill the radiator with coolant up to
the filler opening and also add it to the
reservoir up to the MAX level
A. Start the
engine and allow the engine coolant tem-
perature gauge to rise until it reaches nor- mal operating temperature. For additional
information, refer to “Engine coolant tem-
perature gauge” in the “Instruments and
controls” section of this manual. Turn off
the engine once the engine coolant tem-
perature has reached normal operating
range. Allow the engine coolant to cool to
ambient temperature. Recheck the cool-
ant level in the reservoir and add coolant to
the MAX level if necessary.
This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the "Mainte-
nance and schedules" section of this
manual.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
