2021 NISSAN MAXIMA climate control

AUTOMATIC OPERATION
Cooling and/or dehumidified
heating (AUTO)
This mode may be used all year round as
the system automatically works to keep a
constant temperature. Air flow distribution
and fan speed are also controlled
automatically.
1. Press the AUTO button on.
2. Turn the temperature control dial to thelef t or right to set the desired
temperature.
• The temperature of the passenger com- partment will be maintained automati-
cally. Air flow distribution 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 malfunction.
3. You can individually set driver's and front passenger's side temperature using
each temperature control dial. When the
DUAL button is pressed or passenger's
side temperature dial is turned, the
DUAL indicator will come on. To turn off
the passenger's side temperature con-
trol, press the DUAL button.
Heating (A/C OFF)
The air conditioner does not activate. When
you need to heat only, use this mode.
1. Press the AUTO button.
2. Turn the temperature control dial to set the desired temperature.
• The temperature of the passenger com- partment will be maintained automati-
cally. Air flow distribution and fan speed
are also controlled automatically.
• Do not set the temperature lower than the outside air temperature. Otherwise,
the system may not work properly.
• Not recommended if windows fog up.
Dehumidified defrosting or
defogging
1. Press thefront defroster button on.
2. Turn the temperature control dial to set the maximum temperature to aid in de-
frosting or defogging.
• To quickly remove ice from the outside of the windows, use the
fan speed con-
trol buttons to set the fan speed to
maximum. • As soon as possible af ter the windshield
is clean, press the AUTO button to return
to the automatic mode.
• When the
front defroster button is
pressed, the air conditioner will automati-
cally be turned on at outside tempera-
tures above 36°F (2°C). The air recirculate
mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further improve the
defogging performance. When the air re-
circulate mode automatically turns off,
the air fresh mode will automatically turn
on.
Remote Engine Start with
Intelligent Climate Control (if so
equipped)
Vehicles equipped with automatic climate
controls and Remote Engine Start function
may go into automatic heating or cooling
mode when Remote Engine Start is acti-
vated depending on outside and cabin
temperatures. During this period, the cli-
mate control display and buttons will be
inoperable until the ignition switch is
turned on. In Remote Engine Start defrost-
ing mode, the rear window defroster and
heated steering wheel (if so equipped) may
be activated automatically.

OPERATING TIPS
The sunload sensor, located on the top
center of the instrument panel, helps the
system maintain a constant temperature.
Do not put anything on or around this
sensor.• When the climate system is in automatic
operation and the engine coolant tem-
perature and outside air temperature are
low, the air flow outlet may default to de-
froster mode for a maximum of 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant
temperature warms up, the air flow outlet
will return to foot mode and operation will
continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode or side demist vent outlets for a
maximum of 15 seconds. This may occur
when the previous climate setting was
turned off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, the air
flow outlet will return to previous settings,
and operation will continue normally. To
exit, press any climate control button. • Keep the moonroof (if so equipped)
closed while the air conditioner is in
operation.
• If you feel that the air flow mode you have selected and the outlets the air is coming
out do not match, select the
mode.
• When you change the air flow mode, you may feel air flow from the foot outlets for
just a moment. This is not a malfunction.

When installing a CB, ham radio or car
phone in your vehicle, be sure to observe
the following precautions; otherwise, the
new equipment may adversely affect the
engine control system and other electronic
parts.
WARNING
• A cellular phone should not be used
for any purpose while driving so full
attention may be given to vehicle op-
eration. Some jurisdictions prohibit
the use of cellular 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 recom-
mended. Exercise extreme caution at
all times so full attention may be
given to vehicle operation.
• If you are unable to devote full atten-
tion to vehicle operation while talk-
ing on the phone, pull off the road to
a safe location and stop your vehicle.
CAUTION
• Keep the antenna as far away as pos-
sible from the electronic control
modules.
• Keep the antenna wire more than 8 in
(20 cm) away from the electronic
control system harnesses. 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.

DOT (Department of Transportation) Qual-
ity Grades: All passenger car tires must
conform to federal safety requirements in
addition to these grades.
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature
A
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.Traction AA, A, B and C
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades repre-
sent the tire's ability to stop on wet pave-
ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include ac-
celeration, cornering, hydroplaning, or
peak traction characteristics. Temperature A, B and C
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat, and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109. Grades
B and A represent higher levels of perfor-
mance on the laboratory test wheel than
the minimum required by law.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in combi-
nation, can cause heat build-up and
possible tire failure.
