2021 NISSAN ARMADA heater

WARNING
.The air conditioner cooling func-
tion operates only when the en-
gine is running.
. Do not leave children or adults
who would normally require the
support of others alone in your
vehicle. Pets should not be left
alone either. On hot, sunny days,
temperatures in a closed vehicle
could quickly become high en-
ough 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.
. Do not adjust the heating and air
conditioning controls while driv-
ing so that full attention may be
given to vehicle operation.
Start the engine and operate the heater
and air conditioner system.
NOTE:
. Odors from inside and outside the
vehicle can build up in the air condi-
tioner unit. Odor can enter the pas-
senger compartment through the vents.
. When parking, set the heater and air
conditioner controls to turn off air
recirculation to allow fresh air into
the passenger compartment. This
should help reduce odors inside the
vehicle.

OPERATING TIPS
When the engine coolant temperature
and outside air temperature are low, the
air flow from the foot outlets may not
operate. However, this is not a malfunc-
tion. After the coolant temperature
warms up, the air flow from the foot
outlets will operate normally.
The sensors
andlocated on the
instrument panel help maintain a con-
stant temperature. Do not put anything
on or around the sensors.
LINKING INTELLIGENT KEY (if so
equipped)
The air conditioner system settings can
be memorized for each Intelligent Key.
For more details, see “Setting memory
function” (P.3-42).
IN-CABIN MICROFILTER
The air conditioner system is equipped
with an in-cabin microfilter which collects
dirt, pollen, dust, etc.
To make sure the air conditioner heats,
defogs, and ventilates efficiently, replace
the filter in accordance with the specified
maintenance intervals listed in the “9.
Maintenance and schedules” section. It is
recommended to see a NISSAN dealer to
replace the filter.
The filter should be replaced if the air flow decreases significantly or if win-
dows fog up easily when operating the
heater or air conditioner.
SERVICING AIR CONDITIONER
The air conditioner system in your NISSAN
is charged with a refrigerant designed
with the environment in mind.
This re-
frigerant will not harm the earth’s
ozone layer. However, special charging
equipment and lubricant are required
when servicing your NISSAN air condi-
tioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. (See “Capa-
cities and recommended fluids/lubri-
cants” (P.10-2) for air conditioner system
refrigerant and lubricant recommenda-
tions.)
Your NISSAN dealer will be able to service
your environmentally friendly air condi-
tioner system.
WARNING
The system contains refrigerant un-
der high pressure. To avoid personal
injury, any air conditioner service
should be done only by an experi-
enced technician with the proper
equipment.
WINDOW ANTENNA
The antenna pattern is printed inside the
rear side glass.
CAUTION
. Do not place metalized film near
the 3rd row seat window or at-
tach any metal parts to it. This
may cause poor reception or
noise.
. When cleaning the inside of the
rear side window, be careful not
to scratch or damage the rear
side window antenna. Lightly
wipe along the antenna with a
dampened soft cloth.

SATELLITE ANTENNA
There is a satellite antenna on the rear
part of the vehicle roof.When installing a car phone or a CB radio
in your vehicle, be sure to observe the
following cautions, otherwise the new
equipment may adversely affect the elec-
tronic control modules and electronic
control system harness.
WARNING
.
A cellular phone should not be
used for any purpose while driv-
ing so full attention may be given
to vehicle operation. Some juris-
dictions prohibit the use of cellu-
lar phones while driving.
. If you must make a call while your
vehicle is in motion, the hands-
free cellular phone operational
mode (if so equipped) is highly
recommended. Exercise extreme
caution at all times so full atten-
tion may be given to vehicle
operation.
. If a conversation in a moving
vehicle requires you to take
notes, pull off the road to a safe
location and stop your vehicle
before doing so.
CAUTION
.Keep the antenna as far away as
possible from the electronic con-
trol modules.
. Keep the antenna wire more than
8 in (20 cm) away from the
electronic control system har-
ness. Do not route the antenna
wire next to any harness.
. Adjust the antenna standing-
wave ratio as recommended by
the manufacturer.
. Connect the ground wire from the
CB radio chassis to the body.
. For details, it is recommended
you visit a NISSAN dealer.
