2021 NISSAN ARMADA maintenance

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.

dry grass, waste paper or rags.
They may ignite and cause a fire.
CAUTION
.Do not use leaded gasoline. De-
posits from leaded gasoline ser-
iously reduce the three-way
catalyst’s ability to help reduce
exhaust pollutants.
. Keep your engine tuned up. Mal-
functions in the ignition, fuel in-
jection, or electrical systems can
cause overrich fuel flow into the
three-way catalyst, causing it to
overheat. Do not keep driving if
the engine misfires, or if notice-
able loss of performance or other
unusual operating conditions are
detected. Have the vehicle in-
spected. It is recommended you
visit a NISSAN dealer for this
service.
. Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire,
damaging the three-way catalyst.
. Do not race the engine while
warming it up. .
Do not push or tow your vehicle
to start the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire infla-
tion pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should deter-
mine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illumi-
nates a low tire pressure telltale when
one or more of your tires is significantly
under-inflated. Accordingly, when the low
tire pressure telltale illuminates, you
should stop and check your tires as soon
as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect
the vehicle’s handling and stopping abil-
ity. Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating prop-
erly. The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for
approximately one minute and then re-
main continuously illuminated. This se-
quence will continue upon subsequent
vehicle start-ups as long as the malfunc-
tion exists. When the malfunction indica-
tor is illuminated, the system may not be
able to detect or signal low tire pressure
as intended. TPMS malfunctions may
occur for a variety of reasons, including
the installation of replacement or alter-
nate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires
or wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.

5-12Starting and driving
result in serious vehicle damage
or personal injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel
dynamometer (such as the dy-
namometers used by some
states for emissions testing), or
similar equipment even if the
other two wheels are raised off
the ground. Make sure you inform
test facility personnel that your
vehicle is equipped with 4WD
before it is placed on a dynam-
ometer. Using the wrong test
equipment may result in drive-
train damage or unexpected ve-
hicle movement which could
result in serious vehicle damage
or personal injury (4WD models).
. When a wheel is off the ground
due to an unlevel surface, do not
spin the wheel excessively.
. Accelerating quickly, sharp steer-
ing maneuvers or sudden braking
may cause loss of control.
. If at all possible, avoid sharp
turning maneuvers, particularly
at high speeds. Your vehicle has
a higher center of gravity than a
conventional passenger car. The
vehicle is not designed for cor- nering at the same speeds as
conventional passenger cars.
Failure to operate this vehicle
correctly could result in loss of
control and/or a rollover acci-
dent.
. Always use tires of the same type,
size, brand, construction (bias,
bias-belted or radial), and tread
pattern on all four wheels. Install
tire chains on the rear wheels
when driving on slippery roads
and drive carefully.
. Be sure to check the brakes im-
mediately after driving in mud or
water. See “Brake system” (P.5-
142) for wet brakes.
. Avoid parking your vehicle on
steep hills. If you get out of the
vehicle and it rolls forward, back-
ward or sideways, you could be
injured.
. Whenever you drive off-road
through sand, mud or water as
deep as the wheel hub, more
frequent maintenance may be
required. See the maintenance
schedule shown in the "9. Main-
tenance and schedules" section.
. Spinning the rear wheels on slip-
pery surfaces may cause the 4WD warning light to flash. The 4WD
system may also automatically
switch from the 4WD mode to
the 2WD mode. This could reduce
traction. Be especially careful
when towing a trailer (4WD mod-
els).

SYSTEM TEMPORARILY UNAVAIL-
ABLE
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F (40°C) and then
started, the TSR system may be deacti-
vated automatically. The “Unavailable
High Cabin Temperature” warning mes-
sage will appear in the vehicle informa-
tion display.
Action to take:
When the interior temperature is reduced,
the TSR system will resume operating
automatically.
SYSTEM MALFUNCTION
If the TSR system malfunctions it will be
turned off automatically and the TSR
“Malfunction See Owner’s Manual” warn-
ing message will appear in the vehicle
information display.
Action to take
If the warning message appears, pull off
the road at a safe location and stop the
vehicle. Turn the engine off and restart
the engine. If the warning message con-
tinues to appear, have the system checked by a NISSAN dealer.
SYSTEM MAINTENANCE
The TSR system uses the same multi-
sensing front camera unit that is used by
the Lane Departure Warning (LDW) sys-
tem, located above the inside mirror. (See
“System maintenance” (P.5-31).)
WARNING
Failure to follow the warnings and
instructions for proper use of the
LDW system could result in serious
injury or death.
.
This system is only a warning
device to inform the driver of a
potential unintended lane depar-
ture. It will not steer the vehicle or
prevent loss of control. It is the
driver’s responsibility to stay
alert, drive safely, keep the vehi-
cle in the traveling lane, and be in
control of the vehicle at all times.
LANE DEPARTURE WARNING (LDW)

SSD0453
SYSTEM MAINTENANCE
The lane camera unitfor the LDW
system is located above the inside mirror.
To keep the proper operation of the LDW
system and prevent a system malfunc-
tion, be sure to observe the following:
. Always keep the windshield clean.
. Do not attach a sticker (including
transparent material) or install an
accessory near the camera unit.
. Do not place reflective materials, such
as white paper or a mirror, on the
instrument panel. The reflection of
sunlight may adversely affect the
camera unit’s capability of detecting
the lane markers. .
Do not strike or damage the areas
around the camera unit. Do not touch
the camera lens or remove the screw
located on the camera unit. If the
camera unit is damaged due to an
accident, it is recommended that you
visit a NISSAN dealer.
WARNING
Failure to follow the warnings and
instructions for proper use of the I-LI
system could result in serious injury
or death.
.The I-LI system will not steer the
vehicle or prevent loss of control.
It is the driver’s responsibility to
stay alert, drive safely, keep the
vehicle in the traveling lane, and
be in control of the vehicle at all
times.
. The I-LI system is primarily in-
tended for use on well-developed
freeways or highways. It may not
detect the lane markers in certain
road, weather, or driving condi-
tions.
