2017 NISSAN ALTIMA SEDAN cooling

Thebutton will be on the NISSAN Intelli-
gent Key® if the vehicle has remote engine start.
This feature allows the engine to start from out-
side the vehicle.
The following features may be affected when the
remote start feature is used:
● Vehicles with a manual climate control sys-
tem will default to the last used heating or
cooling mode. ●
Vehicles with an automatic climate control
system will default to either a heating or
cooling mode depending on outside and
cabin temperatures. For additional informa-
tion, refer to “Remote engine start logic” in
the “Monitor, climate, audio, phone and
voice recognition systems” section of the
manual.
Laws in some local communities may restrict the
use of remote starters. For example, some laws
require a person using remote start to have the
vehicle in view. Check local regulations for any
requirements.
Other conditions may affect the function of the
Remote Engine Start feature. For additional infor-
mation, refer to “Conditions the remote start will
not work” in this section.
Other conditions can affect the performance of
the Intelligent Key transmitter. For additional in-
formation, refer to “NISSAN Intelligent Key® with
door and trunk request switches” or “NISSAN
Intelligent Key® without door and trunk request
switches” in this section.

OPERATING RANGE
WARNING
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and or its systems, including entrap-
ment in windows or inadvertent door lock
activation, do not leave children, people
who require the assistance of others or
pets unattended in your vehicle. Addition-
ally, the temperature inside a closed ve-
hicle on a warm day can quickly become
high enough to cause a significant risk of
injury or death to people and pets.
CAUTION
When the Intelligent Key battery is dis-
charged or other strong radio wave
sources are present near the operating
location, the Intelligent Key operating
range becomes narrower, and the Intelli-
gent Key may not function properly.
The remote engine start function can only be
used when the Intelligent Key is within the speci-
fied operating range from the vehicle.
The remote engine start operating range is ap-
proximately 197 ft (60 m) from the vehicle.

WARNING
●The air conditioner cooling function op-
erates only when the engine is running.
● Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves 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 interior
air to become stale and the windows to
fog up.
NOTE: ● Odors from inside and outside the vehicle
can build up in the air conditioner unit. Odor
can enter the passenger compartment
through the vents. ●
When parking, set the heater and air condi-
tioner controls to turn off air recirculation to
allow fresh air into the passenger compart-
ment. This should help reduce odors inside
the vehicle.
CONTROLS
Fan control dial
Thefan control dial turns the fan on and off,
and controls fan speed.

the temperature of the outlet air. To lower the
temperature, turn the dial to the left. To increase
the temperature, turn the dial to the right.
Air recirculation button
On position (Indicator light on):
Interior air is recirculated inside the vehicle.
Press the
button to the ON position when:

position.
4. Turn the temperature control dial to the de- sired position between the middle and the
hot position.
Ventilation
This mode directs outside air to the side and
center vents.
1. Press the
button to the OFF position.
2. Press the
air flow control button.
3. Turn the
fan control dial to the desired
position.
4. Turn the temperature control dial to the de- sired position.

highest setting and the temperature control
to the full HOT position. ●
When the
position is selected, the air
conditioner automatically turns on if the out-
side temperature is more than 36°F (2°C) .
This dehumidifies the air which helps defog
the windshield. The
mode automati-
cally turns off, allowing outside air to be
drawn into the passenger compartment to
further improve the defogging performance.

defog the windshield. The
mode au-
tomatically turns off, allowing outside air to
be drawn into the passenger compartment
to further improve the defogging perfor-
mance.
● The air conditioner is always on in
mode.
3. Turn the temperature control dial to the de- sired position.
Operating tips
●Keep the windows and moonroof closed
while the air conditioner is in operation.
4-20Monitor, climate, audio, phone and voice recognition systems

●After parking in the sun, drive for 2 or 3 min-
utes with the windows open to vent hot air
from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior 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, refer to “If your vehicle
overheats” in the “In case of emer-
gency” section of this manual.

ment will be maintained automatically. Air
flow distribution, air intake control and fan
speed are also controlled automatically. ●
A visible mist may be seen coming from the
vents in hot, humid conditions as the air is
cooled rapidly. This does not indicate a mal-
function.
3. You can individually set driver’s and front passenger’s side temperature using each

Press the AUTO button to return to automatic
control of the fan speed.
Air recirculation
Press theair recirculation button to recir-
culate interior air inside the vehicle.
The air recirculation cannot be activated when
the air conditioner is in the
front defogging
mode.
Fresh air intake
Press thefresh air intake button to draw
outside air into the passenger compartment.
A/C (air conditioner) button
Start the engine, press thefan speed con-
trol buttons to the desired position and press the
button to turn on the air conditioner. To
turn off the air conditioner, press the
but-
ton again.
The air conditioner cooling function oper-
ates only when the engine is running.
Air flow control
Pressing the MODE button manually controls air
flow and selects the air outlet:
— Air flows from center and side
vents.
— Air flows from center and sidevents and foot outlets.
— Air flows mainly from foot outlets.
— Air flows from defroster and footoutlets.
To turn system off
Press the ON-OFF button.
OPERATING TIPS
●When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally. The sunload sensor, located on the top driver’s
side of the instrument panel, helps the system
maintain a constant temperature. Do not put any-
thing on or around this sensor.
