engine INFINITI QX60 2018 Workshop Manual

NOTE:∙ Odors from inside and outside the vehicle can build up in the air conditioner unit.
Odor can enter the passenger compart-
ment through the vents.
∙ When parking, set the heater and air con- ditioner controls to turn off air recircula-
tion to allow fresh air into the passenger
compartment. This should help reduce
odors inside the vehicle.
AUTOMATIC OPERATION
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, in-
take air control, and fan speed are also con-
trolled automatically.
1. Press the AUTO button on. (The indica- tor on the button will illuminate and
AUTO will be displayed.)
2. Operate the driver’s side temperature control buttons.
∙ Adjust the temperature display to about 75°F (24°C) for normal operation. ∙ The temperature of the passenger com-
partment will be maintained automati-
cally. Air flow distribution, intake air con-
trol, and fan speed are also controlled
automatically.
∙ 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.
Dehumidified defrosting or
defogging
1. Press thefront defroster button
on. (The indicator light on the button will
come on.)
2. Operate the temperature control but- tons to set the desired temperature.
∙ To quickly remove ice from the outside of the windows, use the
fan speed
control buttons 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 above 36°F (2°C). The air recir-
culate mode automatically turns off,
allowing outside air to be drawn into the
passenger compartment to further im-
prove 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 and heated steering wheel (if
so equipped) may be activated automatically.
Monitor, climate, audio, phone and voice recognition systems4-35

OPERATING TIPS
The sunload sensor, located on the top driv-
er’s side 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
defroster mode for a maximum of 2 min-
utes 30 seconds. This is not a malfunc-
tion. After the engine coolant tempera-
ture 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 notice
air flow from the foot mode vent outlets
for a maximum of 15 seconds. This is not
a malfunction. After the initial warm air is
expelled, the intake will return to auto-
matic control, air flow outlet will return to
previous settings, and operation will con-
tinue normally. To exit, press any climate
control button.
∙ Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration. ∙ 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 feet vents for
just a moment. This is not 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
vehicle operation.
∙ If you are unable to devote full attention to vehicle operation while talking on the
phone, pull off the road to a safe location
and stop your vehicle.
CAUTION
∙ Keep the antenna as far away as possiblefrom 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 an-
tenna wire next to any harness.
∙ Adjust the antenna standing-wave ratio as recommended by the manufacturer.
∙ Connect the ground wire from the CB ra- dio chassis to the body.
∙ For additional information,, it is recom- mended that you visit an INFINITI re-
tailer for servicing.

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.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-4Starting and driving

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
∙ Keep your engine tuned up. Malfunctions in the ignition, fuel injection, or electrical
systems can cause over rich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that you visit an INFINITI retailer for this
service.
∙ Avoid driving with an extremely low fuel level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
∙ Do not race the engine while warming it up.
∙ Do not push or tow your vehicle to start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all four
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to en-
sure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire, the
TPMS with Tire Inflation Indicator provides
visual and audible signals outside the vehicle
to help you inflate the tires to the recom-
mended COLD tire pressure.Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the shift lever in the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation: 1. Add air to the tire.
2. After a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire. ∙ If the tire is over-inflated more thanapproximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three times. To correct the pressure,
push the core of the valve stem on the
tire briefly to release pressure. When
the pressure reaches the designated
pressure, the horn beeps once.
∙ If the hazard indicator does not flash within approximately 15 seconds after
starting to inflate the tire, it indicates
that the TPMS with Tire Inflation Indi- cator is not operating.
∙ The TPMS will not activate the TPMS with Tire Inflation Indicator under the
following conditions:
– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation de- vice is not sufficient to inflate the tire.
– There is a malfunction in the TPMS system.
– There is a malfunction in the horn or hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor is low.
∙ If the TPMS with Tire Inflation Indica- tor does not operate due to TPMS
interference, move the vehicle about
3 ft (1 m) backward or forward and try
again.
If the TPMS with Tire Inflation Indicator is
not working, use a tire pressure gauge.
5-8Starting and driving

INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people dif-
ferently and most people underestimate the
effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Don’t
drive if your ability to operate your vehicle is
impaired by alcohol, drugs, or some other
physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is mainly
designed for leisure use, unlike a conventional
off-road vehicle.
Remember that 2-wheel drive models are
less capable than all-wheel drive (AWD)
models for rough road driving and extrication
when stuck in deep snow or mud, or the like.Please observe the following precautions:
WARNING
∙ Spinning the front wheels on slippery
surfaces may cause the AWD warning
message to display and the AWD system
to automatically switch from the AWD to
the 2WD mode. This could reduce the
traction. Be especially careful when tow-
ing a trailer (AWD models).
∙ Drive carefully when off the road and avoid dangerous areas. Every person
who drives or rides in this vehicle should
be seated with their seat belt fastened.
This will keep you and your passengers in
position when driving over rough terrain.
∙ Do not drive across steep slopes. Instead drive either straight up or straight down
the slopes. Off-road vehicles can tip over
sideways much more easily than they can
forward or backward.
∙ Many hills are too steep for any vehicle. If you drive up them, you may stall. If you
drive down them, you may not be able to
control your speed. If you drive across
them, you may roll over. ∙ Do not shift gears while driving on down-
hill grades as this could cause loss of con-
trol of the vehicle.
∙ Stay alert when driving to the top of a hill. At the top there could be a drop-off
or other hazard that could cause an
accident.
∙ If your engine stalls or you cannot make it to the top of a steep hill, never attempt to
turn around. Your vehicle could tip or roll
over. Always back straight down in R
(Reverse) gear and apply brakes to con-
trol your speed.
∙ Heavy braking going down a hill could cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
∙ Unsecured cargo can be thrown around when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
∙ Secure heavy loads in the cargo area as far forward and as low as possible. Do not
equip the vehicle with tires larger than
specified in this manual. This could cause
your vehicle to roll over.
Starting and driving5-11

∙ Do not grip the inside or spokes of thesteering wheel when driving off-road.
The steering wheel could move suddenly
and injure your hands. Instead drive with
your fingers and thumbs on the outside of
the rim.
∙ Before operating the vehicle, ensure that the driver and all passengers have their
seat belts fastened.
∙ Always drive with the floor mats in place as the floor may become hot.
∙ Lower your speed when encountering strong crosswinds. With a higher center
of gravity, your INFINITI is more affected
by strong side winds. Slower speeds en-
sure better vehicle control.
∙ Do not drive beyond the performance ca- pability of the tires, even with AWD
engaged.
∙ For AWD equipped vehicles, do not at- tempt to raise two wheels off the ground
and shift the transmission to any drive or
reverse position with the engine running.
Doing so may result in drivetrain damage
or unexpected vehicle movement which
could result in serious vehicle damage or
personal injury. ∙ Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing), or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
∙ When a wheel is off the ground due to an unlevel surface, do not spin the wheel
excessively.
∙ Accelerating quickly, sharp steering ma- neuvers or sudden braking may cause loss
of control.
∙ If at all possible, avoid sharp turning ma- neuvers, particularly at high speeds. Your
INFINITI vehicle has a higher center of
gravity than a passenger car. The vehicle
is not designed for cornering at the same
speeds as passenger cars. Failure to op-
erate this vehicle correctly could result in
loss of control and/or a rollover accident. ∙ Always use tires of the same type, size,
brand, construction (bias, bias-belted, or
radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
∙ Be sure to check the brakes immediately after driving in mud or water. For addi-
tional information, refer to “Brake pre-
cautions” in this section.
∙ Avoid parking your vehicle on steep hills. If you get out of the vehicle and it rolls
forward, backward or sideways, you
could be injured.
∙ Whenever you drive off-road through sand, mud or water as deep as the wheel
hub, more frequent maintenance may be
required. For additional information, re-
fer to “Maintenance under severe oper-
ating conditions” in the “Maintenance
and schedules” section of this manual.
