2023 INFINITI QX60 engine

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.
LTI2587
10-6Technical and consumer information

Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is impor-
tant to select the engine oil viscosity based on
the temperatures at which the vehicle will be
operated before the next oil change. Choos-
ing an oil viscosity other than that recom-
mended could cause serious engine damage.
Selecting the correct oil filter
Your new INFINITI vehicle is equipped with a
high-quality Genuine NISSAN oil filter. When
replacing, use a Genuine NISSAN oil filter or
its equivalent for the reason described in
“Change intervals”.
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using engine oil and
filters that are not of the specified quality, or
exceeding recommended oil and filter change
intervals could reduce engine life. Damage to
the engine caused by improper maintenance
or use of incorrect oil and filter quality and/or
viscosity is not covered by the INFINITI New
Vehicle Limited Warranty.Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter change
intervals depend upon how you use your
vehicle.
Operation under the following conditions
may require more frequent oil and filter
changes:
• repeated short distance driving at cold out-
side temperatures
• driving in dusty conditions
• extensive idling
• towing a trailer
• stop and go commuting
For additional information, see the “Mainte-
nance and schedules” section of this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFO-1234yf (R-1234yf) and NISSAN A/C
system oil Type PAG (VC100YF) or the ex-
act equivalents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFO-1234yf (R-1234yf) in
your INFINITI vehicle does not harm the
earth's ozone layer. Although this refrigerant
does not affect the earth's atmosphere, cer-
tain government regulations require the re-
covery and recycling of any refrigerant during
automotive air conditioner system service. Air
conditioner system should only be serviced by
trained and certified technicians to ensure
proper and safe operation (SAE J2845). An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant. Only
new and SAEJ2842 certified evaporator(s)
shall be used as replacement parts.
A damaged or leaking air conditioning evapo-
rator shall never be repaired or replaced with
one removed from a used or salvaged vehicle.
To replace a damaged or leaking evaporator,
use only new and SAE J2842 certified
evaporator(s). It is recommended that you
visit an INFINITI retailer when servicing your
air conditioner system.

SPECIFICATIONS
10-8Technical and consumer information

When planning to drive your INFINITI ve-
hicle in another country,you should first find
out if the fuel available is suitable for your
vehicle's engine.
Using fuel with an octane rating that is too
low may cause engine damage. All gasoline
vehicles must be operated with unleaded
gasoline. Therefore, avoid taking your vehicle
to areas where appropriate fuel is not
available.
When transferring the registration of your
vehicle to another country, state, province
or district, it may be necessary to modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.
When any vehicle is to be taken into another
country, state, province or district and reg-
istered, its modifications, transportation,
and registration are the responsibility of the
user. INFINITI is not responsible for any in-
convenience that may result.

WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and performance
and may lead to accidents.
CAUTION
• Do not tow a trailer or haul a heavy load
for the first 500 miles (805 km). Your
engine, axle or other parts could be
damaged.
• For the first 500 miles (805 km) that you
tow a trailer, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other
parts of your vehicle wear in at the
heavier loads.
NOTE:
Tow hitches are available as an accessory for
this vehicle. Please visit an INFINITI retailer
for additional equipment required for this
accessory.
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer places addi-
tional loads on your vehicle's engine, drive
train, steering, braking and other systems.
An INFINITI Towing Guide (U.S. only) is avail-
able on the website at www.InfinitiUSA.com.
This guide includes information on trailer
towing capability and the special equipment
required for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed
the value specified in the following Towing
Load/Specification Chart found in this sec-
tion. The total trailer load equals trailer
weight plus its cargo weight.
• When towing a trailer load of 3,500 lbs.
(1,587 kg) or more, trailers with a brake
system MUST be used.
The maximum Gross Combined Weight Rat-
ing (GCWR) should not exceed the value
specified in the following Towing Load/
Specification Chart. The GCWR equals the combined weight of
the towing vehicle (including passengers and
cargo) plus the total trailer load. Towing
loads greater than these or using improper
towing equipment could adversely affect ve-
hicle handling, braking and performance.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer loads,
but also the places you plan to tow. Tow
weights appropriate for level highway driving
may have to be reduced for low traction situ-
ations (for example, on slippery boat ramps).
LTI2582
TOWING A TRAILER
10-20Technical 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.
