climate control INFINITI QX30 2018 User Guide

NOTE
Regardless of the air distribution setting,
airflow is always directed through the side
air ventilators. The side air ventilators can
only be closed if the adjusters are turned
clockwise until they engage.
To set the air distribution:
1. Make sure the engine is running.
2. Press the
orbutton repeat-
edly until the desired symbol appears in
the display.
Setting the airflow
1. Make sure the ignition switch is in the ON position.
2. To increase or reduce airflow: press the
orbutton.
Switching the ZONE function
on/off
This function is only available with automatic
climate control.
To activate: press the
button. The in-
dicator light in thebutton lights up. The
temperature setting for the driver's side is not
adopted for the front-passenger side.
To deactivate: press the
button. The
indicator light in thebutton goes out. The temperature setting for the driver's side
is adopted for the front-passenger side.
Defogging the windshield
You can use this function to de-ice the wind-
shield or to defog the inside of the windshield
and the side windows.
NOTE
You should only select the "Windshield de-
misting" function until the windshield is clear
again.
Activating the "Windshield demisting"
function:
Make sure the ignition switch is in the ON
position.
To activate: press the
button The indi-
cator light in thebutton lights up.
The climate control system switches to the
following functions:
•High airflow
•High temperature
•Air distribution to the windshield and front
side windows
•Air-recirculation mode off NOTE
•The "Windshield demisting" function auto-
matically sets the blower output to the
optimum demisting effect. As a result, the
airflow may increase or decrease auto-
matically after the
button is pressed.
•You can adjust the blower output manu-
ally while the "Windshield demisting" func-
tion is in operation. Press the
orbutton.
Deactivating the "Windshield demisting"
function:
Press the
button. The indicator light in
thebutton goes out. The previous set-
tings are reactivated Air-recirculation mode
remains deactivated.

DOT (Department Of Transportation) Qual-
ity Grades: All passenger car tires must con-
form to federal safety requirements in addi-
tion 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 rating
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 govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon ac-
tual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
TRACTION AA, A, B AND C
The traction grades, from highest to lowest,
are AA, A, B and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of as-
phalt 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 acceleration,
cornering, hydroplaning, or peak traction
characteristics.
TEMPERATURE A, B AND C
The temperature grades A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dissi-
pate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive 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 Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levelsof performance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, ei-
ther separately or in combination, can
cause heat build-up and possible tire
failure.
