2023 NISSAN SENTRA cooling

Thebutton will be on the NISSAN
Intelligent Key® if the vehicle has Remote
Engine Start. This feature allows the engine
to start from outside the vehicle.
The following features may be affected
when the Remote Engine Start feature is
used:
• Vehicles with a manual climate control system will default to the last used heat-
ing or cooling mode. • Vehicles with an automatic climate con-
trol system may default to either a heat-
ing or cooling mode depending on out-
side and cabin temperatures. For
additional information, see “Remote En-
gine Start with Intelligent Climate Control”
(P. 4-41).
Laws in some local communities may re-
strict or prohibit the use of the Remote
Engine Start, or the amount of time a
parked engine may idle. For example, some
laws require a person using Remote Engine
Start to have the vehicle in view or may
restrict idling time except in freezing tem-
peratures. Check local regulations for any
requirements.
Other conditions may affect the function of
the Remote Engine Start feature. For addi-
tional information, see “Conditions the Re-
mote Engine Start will not work” (P. 3-20).
Other conditions can affect the perfor-
mance of the Intelligent Key transmitter.
For additional information, see “NISSAN In-
telligent Key®” (P. 3-7).
REMOTE ENGINE START
OPERATING RANGE
WARNING
• To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
• Do not use Remote Engine Start in
closed spaces such as a garage. Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.

WARNING
• The air conditioner cooling function
operates only when the engine is
running.
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
• Do not use the recirculation mode for
long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up.
NOTE:
• Odors from inside and outside the ve- hicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.
• When parking, set the heater and air conditioner controls to turn off air re-
circulation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.LHA4783

2. Turn the
fan speed control dial to
the desired position. • When the
orare selected, the
air conditioner automatically turns on if
the outside temperature is more than
36°F (2°C). This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further improve the
defogging performance.
3. Turn the temperature control dial to the desired position.
Operating tips
• Keep the windows closed while the airconditioner is in operation.
• Af ter parking in the sun, drive for 2 or 3 minutes with the windows open to vent
hot air from the passenger compart-
ment. Then, close the windows. This al-
lows the air conditioner to cool the inte-
rior more quickly.
• The air conditioning system should be operated for approximately 10 minutes at
least once a month. This helps prevent
damage to the system due to lack of
lubrication.
• A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.

• If the engine coolant temperature gaugeindicates engine coolant temperature
over the normal range, turn the air condi-
tioner off. For additional information, see
“If your vehicle overheats” (P. 6-11).
• When Remote Engine Start (if so equipped) is activated, the manual cli-
mate control system will default to the
last used heating or cooling mode.
