2021 NISSAN TITAN Owner´s Manual

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.

and center vents.
1. Press the
button to the off position.
The indicator light on thebutton
willgooff.
2. Press the
air flow control button.
3. Turn the
fan speed control dial to

Defrosting or defogging
This mode directs the air to the defrost
outlets to defrost/defog the windows.
1. Press the
defrost/defog button.
2. Turn the
fan speed control dial to
the desired position.
3. Turn the temperature control dial to the desired position between the middle

ture control to the full HOT position.
• When the
position is 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. Under this con-
dition, the indicator light on the A/C but-
ton indicator will not turn on if the user
had selected the A/C off. Turning off the
air conditioning via the A/C button is not
allowed In this mode. If the A/C button
indicator was on when entering this
mode, and the A/C button is selected in
this mode, the A/C button indicator will
turn off, but the A/C compressor will still
be automatically enabled. The recircula-
tion button indicator will not illuminate if

• When theposition is selected, the
air conditioner automatically turns on if
the outside temperature is more than
36°F (2°C). If the
air flow control
button is selected for more than 1 minute,
the air conditioning system will continue
to operate until the
fan speed con-
trol dial is turned to OFF, the vehicle is
shut off, or the A/C button is used to turn
off the compressor even if the air flow
control dial is turned to a position other
than the
position. This dehumidi-
fies the air which helps defog the wind-
shield. Under this condition, the indicator
light on the A/C button indicator will not
turn on if the user had selected A/C off.
Turning off the air conditioning via the
A/C button is not allowed in this mode. If
the A/C button indicator was on when
entering this mode, and the A/C button is
selected in this mode, the A/C compres-
sor will still be automatically enabled. It is
recommended that
mode be
turned off for maximum defogging. The
recirculation button can be selected in
this mode to block outside odors. How-
ever, for maximum defogging in this
mode, it is recommended to turn recircu-
lation off when possible.

When theorpositions are se-
lected, the air conditioner automatically
turns on if the outside temperature is more
than 36°F (2°C). The air conditioning system
will continue to operate until the
fan
speed control dial is turned to OFF, the air
conditioner is turned OFF, or the vehicle is
shut off. If a position other than the
front defrost air flow button is selected, the
A/C compressor will not turn off even if the
user had selected A/C off prior to entering
defrost. In
front defrost orfoot
defrost the indicator light on the A/C but-
ton will not turn on if the user had selected
A/C off. Turning off the air conditioning via
the A/C button is not allowed in this mode.
If the A/C button indicator was on when
entering this mode, and the A/C button is
selected in this mode, the A/C button indi-
cator will turn off, but the A/C compressor
will still be automatically enabled. This de-
humidifies the air which helps defog the
windshield. The
mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment to fur-
ther 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 pre-
vent 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
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, see “If your vehicle over-
heats” (P. 6-12).
AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. For addi-
tional information on heating and cooling,
see “Heater and air conditioner (manual)”
(P. 4-29). The air recirculation (
) but-
ton should always be in the OFF position
for heating and defrosting.
