engine INFINITI QX80 2014 Workshop Manual

WARNING
.The air conditioner cooling function
operates only when the engine is run-
ning.
. Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. 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.
. Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
. Do not adjust the heating and air
conditioning controls while driving so
that full attention may be given to
vehicle operation.
Start the engine and operate the automatic
climate control system.

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
*Aand*Blocated on the
instrument panel help maintain a constant
temperature. Do not put anything on or
around the sensors.
LINKING INTELLIGENT KEY
The Climate control system settings can be
memorized for each Intelligent Key. For
more details, see “Setting memory func-
tion” in the “3. Pre-driving checks and
adjustments” section.
IN-CABIN MICROFILTER
Models without Advanced Climate Control
System:
The climate control system is equipped
with an in-cabin microfilter which collects
dirt, pollen, dust, etc.
Models with Advanced Climate Control
System:

The climate control system is equipped
with a natural grape seed polyphenol filter
which collects and neutralizes dirt, pollen,
dust, etc.
To make sure that the air conditioner
heats, defogs and ventilates efficiently,
replace the filter in accordance with the
maintenance schedule in the INFINITI Ser-
vice and Maintenance Guide. To replace the
filter, contact an INFINITI retailer.
The filter should be replaced if the air flow
decreases significantly or if windows fog
up easily when operating the heater or air
conditioner.
SERVICING CLIMATE CONTROL
The climate control system in your INFINITI
is charged with a refrigerant designed with
the environment in mind.This refrigerant
will not harm the earth’s ozone layer.
However, special charging equipment and
lubricant are required when servicing your
INFINITI air conditioner. Using improper
refrigerants or lubricants will cause severe
damage to your climate control system.
(See “Capacities and recommended fuel/
lubricants” in the“9. Technical and con-
sumer information” section for climate
control system refrigerant and lubricant recommendations.)
Your INFINITI retailer will be able to service
your environmentally friendly climate con-
trol system.
WARNING
The system contains refrigerant under high
pressure. To avoid personal injury, any air
conditioner service should be done only by
an experienced technician with the proper
equipment.
AUDIO OPERATION PRECAUTIONS
Radio
Push the ignition switch to the ACC or ON
position and push the radio band select
button to turn on the radio. If you listen to
the radio with the engine not running, the
ignition switch should be pushed to the
ACC position.
Radio reception is affected by station
signal strength, distance from radio trans-
mitter, buildings, bridges, mountains and
other external influences. Intermittent
changes in reception quality normally are
caused by these external influences.
Using a cellular phone in or near the
vehicle may influence radio reception
quality.
Radio reception:
Your INFINITI radio system is equipped with
state-of-the-art electronic circuits to en-
hance radio reception. These circuits are
designed to extend reception range, and to
enhance the quality of that reception.
However there are some general character-
istics of both FM and AM radio signals that
can affect radio reception quality in a
moving vehicle, even when the finest

WARNING
.Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. They could
accidentally 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 to help prevent
it from sliding or shifting. Do not place
cargo higher than the seatbacks. In a
sudden stop or collision, unsecured
cargo could cause personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or death.
. If you suspect that exhaust fumes are
entering 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 lift gate closed while driving,
otherwise exhaust gases could be drawn
into the passenger compartment. If you
must drive with the lift gate open, follow
these precautions:
1) Open all the windows.
2) Set the
air recirculation to off
and the fan control to high to
circulate the air.
. If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the lift gate or the body,
follow the manufacturer’s recommenda-
tion to prevent carbon monoxide entry
into the vehicle.
. The exhaust system and body should be
inspected by a qualified mechanic when-
ever:
—The vehicle is raised for service.
—You suspect that exhaust fumes are
entering into the passenger compart-
ment.
—You notice a change in the sound ofthe exhaust system.
—You have had an accident involvingdamage to the exhaust system,
underbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission
control device installed in the exhaust
system. Exhaust gases in the three-way
catalyst are burned at high temperatures to
help reduce pollutants.
WARNING
. The exhaust gas and the exhaust system
are very hot. Keep people, animals or
flammable materials away from the
exhaust system components.
. Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
