2023 INFINITI QX60 engine overheat

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.

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.

Octane rating tips
Using unleaded gasoline with an octane rat-
ing lower than recommended can cause per-
sistent, heavy “spark knock.” (“Spark knock”
is a metallic rapping noise.) If severe, this can
lead to engine damage. If you detect a per-
sistent heavy spark knock even when using
gasoline of the stated octane rating, or if you
hear steady spark knock while holding a
steady speed on level roads, it is recom-
mended that you have an INFINITI retailer
correct the condition. Failure to correct the
condition is misuse of the vehicle, for which
INFINITI is not responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle checked.
It is recommended that you visit an INFINITI
retailer.
However, now and then you may notice light
spark knock for a short time while accelerat-
ing or driving up hills. This is not a cause for
concern, because you get the greatest fuel
benefit when there is light spark knock for a
short time under heavy engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade,
quality and viscosity engine oil to ensure sat-
isfactory engine life and performance. For
additional information, see "Recommended
fluids/lubricants and capacities" (P. 10-2).
INFINITI recommends the use of an energy
conserving oil in order to improve fuel
economy.Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification or
International Lubricant Standardization and
Approval Committee (ILSAC) certification
and SAE viscosity standard. These oils have
the API certification mark on the front of the
container. Oils which do not have the speci-
fied quality label should not be used as they
could cause engine damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.

10-6Technical and consumer information

Temperature conditions can also affect tow-
ing. For example, towing a heavy trailer in
high outside temperatures on graded roads
can affect engine performance and cause
overheating. Vehicle speed may decrease un-
der high load. Plan your trip carefully to ac-
count for trailer and vehicle load, weather
and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving.
If the vehicle cannot maintain a safe driving
speed, pull to the side of the road in a safe
area. Allow the engine to cool and return
to normal operation. For additional infor-
mation, see “If your vehicle overheats”
(P. 6-14).
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by
INFINITI warranties.
Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load be-
tween 10 - 15% of the total trailer load or use
the trailer tongue load specified by the trailer
manufacturer. The tongue load must be
within the maximum tongue load limits
shown in the following “Towing Load/
Specification” chart. If the tongue load be-
comes excessive, rearrange cargo to allow
for proper tongue load.
Maximum Gross Vehicle Weight
(GVW)/maximum Gross Axle
Weight (GAW)
The GVW of the towing vehicle must not
exceed the Gross Vehicle Weight Rating
(GVWR) shown on the F.M.V.S.S./C.M.V.S.S.
certification label. The GVW equals the com-
bined weight of the unloaded vehicle, pas-
sengers, luggage, hitch, trailer tongue load
and any other optional equipment. In addi-
tion, front or rear GAW must not exceed the
Gross Axle Weight Rating (GAWR) shown on
the F.M.V.S.S./C.M.V.S.S. certification label.

• Lock the trailer hitch coupler with a pin orlock to prevent the coupler from inadver-
tently becoming unlatched.
• Avoid abrupt starts, acceleration or stops.
• Avoid sharp turns or lane changes.
• Always drive your vehicle at a moderate speed.
• When backing up, hold the bottom of the steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and
back up slowly. If possible, have someone
guide you when you are backing up.
Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:
CAUTION
If you push the park button to engage the P
(Park) position before blocking the wheels
and applying the parking brake, transmis-
sion damage could occur. 1. Apply and hold the brake pedal.
2. Have someone place blocks on the down-
hill side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the blocks
absorb the vehicle load.
4. Apply the parking brake.
5. Push the park button to engage the P (Park) position.
6. Turn off the engine.
To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks. • While going downhill, the weight of the
trailer pushing on the tow vehicle may de-
crease overall stability. Therefore, to main-
tain adequate control, reduce your speed
and shift to a lower gear. Avoid long or
repeated use of the brakes when descend-
ing a hill, as this reduces their effectiveness
and could cause overheating. Shifting to a
lower gear instead provides “engine brak-
ing” and reduces the need to brake as
frequently.
• If the engine coolant temperature rises to a high temperature, see “If your vehicle over-
heats” (P. 6-14).
• Trailer towing requires more fuel than nor- mal circumstances.
• Avoid towing a trailer for your vehicle's first 500 miles (805 km).
•For the first 500 miles (805 km) that you do
tow, do not drive over 50 mph (80 km/h).
• Have your vehicle serviced more often than at intervals specified in the recommended
maintenance schedule in the “Maintenance
and schedules” section of this manual.
• When making a turn, your trailer wheels will be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
Technical and consumer information10-29

• Crosswinds and rough roads will adverselyaffect vehicle/trailer handling, possibly
causing vehicle sway. When being passed
by larger vehicles, be prepared for possible
changes in crosswinds that could affect
vehicle handling.
Do the following if the trailer begins to sway:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions al-
low. This combination will help stabilize
the vehicle.
– Do not correct trailer sway by steering or applying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of the road
in a safe area.
3. Try to rearrange the trailer load so it is balanced. For additional information, see
“Pre-towing tips” (P. 10-28).
• Be careful when passing other vehicles. Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer
must also pass the other vehicle before you
can safely change lanes. • Downshift the transmission to a lower gear
for engine braking when driving down
steep or long hills. This will help slow the
vehicle without applying the brakes.
• Avoid holding the brake pedal down too long or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
• Increase your following distance to allow for greater stopping distances while tow-
ing a trailer. Anticipate stops and brake
gradually.
• INFINITI recommends that the cruise con- trol not be used while towing a trailer.
• Some states or provinces have specific regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
• Check your hitch, trailer wiring harness connections, and trailer wheel lug nuts af-
ter 50 miles (80 km) of travel and at every
break.
• When launching a boat, don't allow the water level to go over the exhaust tail pipe
or rear bumper.
• Make sure you disconnect the trailer lights before backing the trailer into the water or
the trailer lights may burn out. When towing a trailer, differential gear oil,
transfer fluid and transmission oil/fluid
should be changed more frequently. For ad-
ditional information, see the “Maintenance
and schedules” section of this manual.
FLAT TOWING FOR ALL–WHEEL
DRIVE VEHICLE (if so equipped)
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle behind a recreational vehicle, such
as a motor home.
CAUTION
• Failure to follow these guidelines can re-
sult in severe transmission damage.
• Never flat tow your All-wheel drive
(AWD) vehicle.
• DO NOT tow your All-wheel drive
(AWD) vehicle with any wheels on the
ground. Doing so may cause serious and
expensive damage to the powertrain.
• For emergency towing procedures, see
“Towing recommended by INFINITI”
(P. 6-16).
