2023 INFINITI QX60 engine coolant

IDLING STOP OFF SWITCH
The system can be temporarily deactivated
by pushing the Idling Stop OFF switch. Push-
ing the switch again or restarting the engine
by using the ignition switch will reactivate the
Idling Stop System.
• When the Idling Stop System is deactivatedwhile the engine is running, the engine is
prevented from automatically stopping. • When the Idling Stop System is deactivated
after the engine has been automatically
stopped by the Idling Stop System, the en-
gine will immediately restart if suitable con-
ditions are present. The engine will then be
prevented from automatically stopping
during the same journey.
NOTE:
• The Idling Stop System ON or OFF mes- sage is displayed for a few seconds in the
vehicle information display when the
Idling Stop System OFF switch is pushed.
For additional information, see “Idling
Stop System Display” (P. 5-180).
• The Idling Stop System resets to ON every time the ignition switch is switched from
the OFF position to the ON position.
• It is best to disable the ISS system when towing a trailer. You can do this by pushing
the Idling Stop OFF switch.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, see
“Engine cooling system” (P. 8-4).
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see “Battery” (P. 8-13).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For additional information, see
“Changing engine coolant” (P. 8-5).

5. Start the engine of the booster vehicle andlet it run for a few minutes.
6. Keep the engine speed of the booster ve- hicle at about 2,000 rpm and start the
engine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, place the ignition
switch in the OFF position and wait 3 to 4
seconds before trying again.
7. After starting the engine, carefully discon- nect the negative cable and then the posi-
tive cable.
CAUTION
Automatic transmission models cannot be
push-started. Attempting to do so may
cause transmission damage.WARNING
• Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
• To avoid the danger of being scalded,
never remove the radiator or coolant
reservoir cap while the engine is still hot.
When the radiator or coolant reservoir
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
• Do not open the hood if steam is coming
out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading
and the Low Oil Pressure: See Owner’s
Manual warning message appears in the ve-
hicle information display), or if you feel a lack
of engine power, detect abnormal noise, etc.
take the following steps:
1. Move the vehicle safely off the road, apply the parking brake.
2. Push the park button to shift to the P (Park) position.
Do not stop the engine.

3. Turn off the air conditioner. Open all thewindows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radia-
tor before opening the hood. If steam or
coolant is escaping, turn off the engine.
Do not open the hood further until no
steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the
engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
7. After the engine cools down, check the coolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended that you visit an
INFINITI retailer for this service. When towing your vehicle, all jurisdictional
and local regulations for towing must be fol-
lowed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from an INFINITI retailer. Local ser-
vice operators are generally familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent ac-
cidental damage to your vehicle, INFINITI
recommends having a service operator tow
your vehicle. It is advisable to have the service
operator carefully read the following
precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
• When towing, make sure that the trans-
mission, axles, steering system and pow-
ertrain are in working condition. Use dol-
lies or flatbed if any of the listed systems
are not working.
• Always attach safety chains before
towing.

When performing any inspection or maintenance
work on your vehicle, always take care to pre-
vent serious accidental injury to yourself or dam-
age to the vehicle. The following are general
precautions which should be closely observed.
WARNING
• Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Push the park button to engage the
P (Park) position.
• Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
• It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
• Always wear eye protection whenever
you work on your vehicle.
• Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
• If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
• Never get under the vehicle while it is
supported only by a jack. If it is necessary
to work under the vehicle, support it
with safety stands.
•
Keep smoking materials, flame and sparks
away from the fuel tank and battery.
• Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
• Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
• Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid. •
Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
• Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, see
“Owner’s Manual/Service Manual order in-
formation” (P. 10-36).
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.

The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round antifreeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not necessary.
WARNING
• Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high pressure fluid escaping from the
radiator. For additional information on
precautions, see “If your vehicle over-
heats” (P. 6-14).
• The radiator is equipped with a pressure
type radiator cap. To prevent engine
damage, use only a Genuine NISSAN ra-
diator cap.
CAUTION
• Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.
• When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C). If additional freeze protection
is needed due to weather where you op-
erate your vehicle, add Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
concentrate following the directions on
the container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s instruc-
tions to maintain minimum antifreeze
protection to -34° F (-37° C). The use of
other types of coolant solutions other
than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling system. •
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) (or
equivalent coolant), including Genuine
NISSAN Long Life Antifreeze/Coolant
(green), or the use of non-distilled water
may reduce the life expectancy of the
factory-fill coolant. For additional infor-
mation, see the “Maintenance and
schedules” section of this manual.
ENGINE COOLING SYSTEM
8-4Do-it-yourself

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
OB, add coolant to the MAX
level
OA. If the reservoir is empty, check the
coolant level in the radiator when the engine
is cold. If there is insufficient coolant in the
radiator, fill the radiator with coolant up to
the filler opening and also add it to the reser-
voir up to the MAX level
OA. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years.
Mixing any other type of coolant that is not
equivalent to Genuine NISSAN Long Life
Antifreeze/Coolant (blue), or the use of non-
distilled water will reduce the life expectancy
of the factory-fill coolant. For additional in-
formation, see the "Maintenance and sched-
ules" section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
For additional information on the location of
the engine coolant reservoir, see “Engine
compartment check locations” (P. 8-3).
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant. The service procedure can be found
in the INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING
• To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
• Never remove the radiator or engine
coolant reservoir cap when the engine is
hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
• Avoid direct skin contact with used cool-
ant. If skin contact is made, wash thor-
oughly with soap or hand cleaner as soon
as possible.
• Keep coolant out of the reach of children
and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
