2023 INFINITI QX60 check engine

Doors and engine hood:Check that the doors
and engine hood operate properly. Also en-
sure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary
latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication
frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch fully open. If the hood, trunk, or rear
hatch is not held open, have the gas stays or
struts replaced.
Lights*: Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are miss-
ing, and check for any loose wheel nuts.
Tighten if necessary.
Tire rotation*: Rotate tires at the specified
interval shown in the maintenance schedule.
Tires*: Check the pressure with a gauge
often and always prior to long distance trips. If necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
tire pressure sensor:
It is recommended that
you replace the TPMS tire pressure sensor
assembly when the tires are replaced due to
wear or age.
Wheel alignment and balance: If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect un-
even or abnormal tire wear, there may be a
need for wheel alignment.
If the steering wheel or seat vibrates at nor-
mal highway speeds, wheel balancing may be
needed.
For additional information regarding tires, re-
fer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Windshield: Clean the windshield on a regu-
lar basis. Check the windshield at least
every six months for cracks or other damage.
Have a damaged windshield repaired by a
qualified repair facility. It is recommended
that you have a damaged windshield re-
paired by an INFINITI retailer, or an INFINITI Certified Collision Center. To locate a colli-
sion center in your area, refer to

Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal:
Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Automatic transmission P (Park) position
mechanism: On a fairly steep hill check that
the vehicle is held securely with the shift po-
sition in the P (Park) position without apply-
ing any brakes.
Brake pedal: Check the pedal for smooth op-
eration. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, have your vehicle checked immediately.
It is recommended that you visit an INFINITI
retailer for this service. Keep the floor mat
away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Maintenance and schedules9-3

Parking brake:Check the parking brake op-
eration regularly. The vehicle should be se-
curely held on a fairly steep hill with only the
parking brake applied. If the parking brake
needs adjustment, it is recommended that
you visit an INFINITI retailer for this service.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc., to en-
sure they operate smoothly and all latches
lock securely in every position. Check that the
head restraints/headrests move up and
down smoothly and the locks (if so equipped)
hold securely in all latched positions.
Steering wheel: Check for changes in the
steering system, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner. Windshield wiper and washer*:
Check that
the wipers and washer operate properly and
that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery (for maintenance free batteries)*:
This vehicle is equipped with a sealed main-
tenance free battery. It is recommended that
you visit an INFINITI retailer for this service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic accessories that consume battery power
when the engine is not running (Phone
chargers, GPS, DVD players, etc.).
2. Vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir. Engine coolant level*:
Check the coolant level
when the engine is cold.
Engine drive belt*: Make sure the drive belt is
not frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil
to drain back into the oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have the
exhaust system inspected. It is recommended
that you visit an INFINITI retailer for this
service. For additional information, see “Ex-
haust gas (carbon monoxide)” (P. 5-4).
Fluid leaks: Check under the vehicle for fuel,
oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping
from the air conditioner after use is normal. If
you should notice any leaks or if fuel fumes
are evident, check for the cause and have it
corrected immediately.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure
the hoses have no cracks, deformation, rot or
loose connections.
9-4Maintenance and schedules

Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, oth-
erwise rust may form on the floor pan, frame,
fuel lines and around the exhaust system. At
the end of winter, the underbody should be
thoroughly flushed with plain water, being
careful to clean those areas where mud and
dirt may accumulate. For additional informa-
tion, see “Cleaning exterior” (P. 7-2).
Windshield-washer fluid*: Check that there
is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the sched-
uled maintenance items that should be regu-
larly checked or replaced. The maintenance
schedule indicates at which mileage/time in-
tervals each item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. For ad-
ditional information, see “General mainte-
nance” (P. 9-2).
Items marked with
“*”are recommended by
INFINITI for reliable vehicle operation. You
are not required to perform maintenance on
these items in order to maintain the warran-
ties which come with your INFINITI. Other
maintenance items and intervals are required.
When applicable, additional information can
be found in the “Do-it-yourself” section of
this manual.NOTE:
INFINITI does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on an INFINITI product.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been vali-
dated by INFINITI.

9-6Maintenance and schedules

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

• 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).
10-30Technical and consumer information

WARNING
A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dyna-
mometers used by some states for emis-
sions testing), or similar equipment. Make
sure you inform the test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer. Us-
ing the wrong test equipment may result in
transmission damage or unexpected ve-
hicle movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready con-
dition” for an Inspection/Maintenance (I/M)
test of the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving pat-
terns. Usually, the ready condition can be
obtained by ordinary usage of the vehicle. If a powertrain system component is repaired
or the battery is disconnected, the vehicle
may be reset to a “not ready” condition. Be-
fore taking the I/M test, check the vehicle's
inspection/maintenance test readiness con-
dition. Place the ignition switch in the ON
position without starting the engine. If the
Malfunction Indicator Light (MIL) comes on
steady for 20 seconds and then blinks for
10 seconds , the I/M test condition is “not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”. It is
recommended that you visit an INFINITI re-
tailer to set the “ready condition” or to pre-
pare the vehicle for testing.
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle's systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety sys-
tems for a short period of time, typically 30
seconds or less. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
• Sounds are not recorded.
These data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-
trivial crash situation occurs; no data are re-
corded by the EDR under normal driving con-
ditions and no personal data (e.g., name,
gender, age, and crash location) are recorded.
However, other parties, such as law enforce-
ment, could combine the EDR data with the
