2021 INFINITI QX80 display

detects odors outside the vehicle such as
pulp or chemicals, and exhaust gas such as
gasoline or diesel. When such odors or gases
are detected, the display and the system
automatically change from the fresh air
mode to the recirculation mode.
When the automatic air circulation control
mode is on, for the first 5 minutes, the air
recirculation mode is selected to prevent
dust, dirt and pollen from entering the
vehicle and to clean the air inside of the
vehicle.
After 5 minutes, the sensor detects exhaust
gas and automatically alternates between
the air recirculation mode and the fresh air
mode.
NOTE:
The automatic air recirculation mode can be
activated under the following conditions.
.The air flow control is not in the wind-
shield defrosting mode (the indicator
light on the “
” front defroster but-
ton is turned off).
. The outside temperature is approxi-
mately 32 °F (0 °C) or above.
Ion control:
The Advanced Climate Control system unit
generates highly concentrated Plasmaclus-
ter
®ions into the air blown from the
ventilators to reduce odor absorbed into the interior trim and to suppress airborne
bacteria. The high-density Plasmacluster
®
ions also have a proven skin moisture
preserving effect.
The Plasmacluster
®icon on the Climate
screen indicates the status of the Plas-
macluster
®ion emission from the system
and changes with the amount of the air flow.

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 malfunction. After
the coolant temperature warms up, the air
flow from the foot outlets will operate
normally.
The sensors
andlocated on the instru-
ment panel help maintain a constant tem-
perature. Do not put anything on or around
the sensors.

5-6Starting and driving
not detect a sudden drop in tire pressure
(for example, a flat tire while driving).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is
inflated to the recommended pressure,
the vehicle must be driven at speeds
above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
. The “Tire Pressure Low Add Air” warning
appears in the vehicle information dis-
play when the low tire pressure warning
light is illuminated and low tire pressure
is detected. The “Tire Pressure Low Add
Air” warning turns off when the low tire
pressure warning light turns off.
The “Tire Pressure Low Add Air” warning
appears each time the ignition switch is
placed in the ON position as long as the
low tire pressure warning light remains
illuminated.
The “Tire Pressure Low Add Air” warning
does not appear if the low tire pressure
warning light illuminates to indicate a
TPMS malfunction.
. Tire pressure rises and falls depending on
the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure after driving
because the tire pressure rises after driving. Low outside temperature can
lower the temperature of the air inside
the tire which can cause a lower tire
inflation pressure. This may cause the
low tire pressure warning light to illumi-
nate. If the warning light illuminates in
low ambient temperature, check the tire
pressure for all four tires.
. You can also check the pressure of all
tires (except the spare tire) on the vehicle
information display. (See “10. Tire pres-
sures” (P.2-32).)
For additional information, see “Low tire
pressure warning light” (P.2-16) and “Tire
Pressure Monitoring System (TPMS) ” (P.6-
3).
WARNING
. If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal injury. Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a spare tire as soon as
possible. If no tire is flat and all tires
are properly inflated, it is recom-
mended you consult an INFINITI
retailer.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
