2020 INFINITI QX50 engine

Start the engine and operate the controls to
activate the air conditioner.
NOTE:∙ Odors from inside and outside the ve-
hicle can build up in the air conditioner
unit. Odor can enter the passenger com-
partment through the vents.
∙ When parking, set the heater and air
conditioner controls to turn off air recir-
culation to allow fresh air into the pas-
senger compartment. This should help
reduce odors inside the vehicle
AUTOMATIC OPERATION
Press the AUTO button to set the automatic
control mode that keeps the air distribution,
temperature and the fan speed automati-
cally.
Cooling and/or dehumidified
heating (AUTO)
This mode may be used all year round as the
system automatically works to keep a con-
stant temperature. Air flow distribution, air
intake control, and fan speed are also con-
trolled automatically. 1. Press the
CLIMATE button on the
lower display menu. The CLIMATE
screen will display on the lower display.
2. Press the AUTO button on. (The indica- tor on the button will illuminate and
AUTO will be displayed on the CLIMATE
screen.)
3. Press the
temperature con-
trol buttons on the driver’s side to set the
desired temperature.
∙ The temperature of the passenger com- partment will be maintained automati-
cally. Air flow distribution, air intake con-
trol 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 indi-
cate a malfunction.
Dehumidified defrosting or
defogging
1. Press thefront defroster button
on. (The indicator light on the button will
come on.) 2. Operate the
temperature
control buttons to set the desired tem-
perature.
∙ To quickly remove ice from the outside of the windows, use the
fan speed
control button or the “
” key to set
the fan speed to maximum.
∙ As soon as possible after 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 auto-
matically be turned on at outside tem-
peratures approximately 32°F (0°C) to
defog the windshield. The air recirculate
mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further improve the
defogging performance.
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 activated
depending on outside and cabin tempera-

tures. During this period, the climate control
display and buttons will be inoperable until
the ignition switch is turned on. In Remote
Engine Start defrosting mode, the rear win-
dow defroster, heated seat (if so equipped)
and heated steering wheel (if so equipped)
may be activated automatically. In Remote
Engine Start cooling mode, the climate con-
trolled seat (if so equipped) may be activated
automatically.
Voice Recognition logic (if so
equipped)
When the climate control system is on, the
fan speed may be automatically lowered so
that commands are more easily recognized.
Fan speed can be adjusted using the
fan
speed decrease and
increase buttons, if
desired.
MANUAL OPERATION
Fan speed control
Press thefan speed increase andfan speed decrease buttons to manually con-
trol the fan speed. Fan speed can also be

so equipped) defroster switch
For additional information, refer to “Rear
window defroster, outside mirror defroster,
and wiper deicer (if so equipped) switch” in
the “Instruments and controls” section of this
manual.
OPERATING TIPS
The sensors,AandBon the instrument
panel, help the system maintain a constant
temperature. Do not put anything on or
around these sensors. ∙ When the engine coolant temperature
and outside air temperature are low, the
air may flow from defroster or feet vents
to initialize automatic heating mode. This
is not a malfunction. After the coolant
temperature warms up, air will flow nor-
mally from the feet vents
∙ 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.

The vehicle is equipped with a shark fin an-
tenna and an antenna pattern is printed in-
side the rear window.
CAUTION
∙ Do not place metalized film near the rearwindow glass or attach any metal parts
to it. This may cause poor reception or
noise.
∙ When cleaning the inside of the rear win- dow, be careful not to scratch or damage
the rear window antenna. Lightly wipe
along the antenna with a dampened soft
cloth. When installing a CB, ham radio or car phone
in your vehicle, be sure to observe the follow-
ing precautions; otherwise, the new equip-
ment 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 atten-
tion may be given to vehicle operation.
Some jurisdictions prohibit the use of cel-
lular phones while driving.
∙ If you must make a call while your vehicle is in motion, the hands free cellular phone
operational mode is highly recom-
mended. Exercise extreme caution at all
times so full attention may be given to

WARNING
∙ Do not leave children or adults whowould normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acciden-
tally 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.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; they con-tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous. It
can cause unconsciousness or death.
∙ If you suspect that exhaust fumes are en- tering the vehicle, drive with all windows
fully open, and have the vehicle inspected
immediately. ∙ Do not run the engine in closed spaces
such as a garage.
∙ Do not park the vehicle with the engine running for any extended length of time.
∙ Keep the rear vent windows, liftgates, doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passenger
compartment. If you must drive with one
of these open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation button
to off and the fan control dial to high
to circulate the air.
∙ If electrical wiring or other cable connec- tions must pass to a trailer through the
seal on the liftgate or the body, follow
the manufacturer’s recommendation to
prevent carbon monoxide entry into the
vehicle.
∙ The exhaust system and body should be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service. b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
∙ The exhaust gas and the exhaust systemare very hot. Keep people, animals or
flammable materials away from the ex-
haust system components.
∙ Do not stop or park the vehicle over flam- mable materials such as dry grass, waste
paper or rags. They may ignite and cause
a fire.
