2020 INFINITI QX60 check engine

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, refer to the “Appearance and care” sec-
tion of this manual.
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, refer to “General main-
tenance” in this section.
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.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to “Recom-
mended fluids/lubricants and capacities” in
the “Technical and consumer information”
section of this manual.
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive belt*:
Check engine drive belt for wear,
fraying or cracking and for proper tension.
Replace any damaged drive belt.
Engine air filter: Replace at specified inter-
vals. When driving for prolonged periods in
dusty conditions, check/replace the filter
more frequently.
EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS
Maintenance and schedules9-5

Engine coolant*:Replace coolant at the
specified interval. When adding or replacing
coolant, be sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue) or
equivalent with the proper mixture. (For ad-
ditional information on the proper mixture for
your area, refer to “Engine cooling system” in
the “Do-it-yourself” section of this manual.)
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
Engine oil and oil filter: Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity refer to
“Recommended fluids/lubricants and capaci-
ties” in the “Technical and consumer informa-
tion” section of this manual.

noise increases. Adjust valve clearance if nec-
essary.
Evaporative emissions control vapor lines*:
Check vapor lines for leaks or looseness.
Tighten connections or replace parts as nec-
essary. Fuel lines*:
Check the fuel hoses, piping and
connections for leaks, looseness, or deterio-
ration. Tighten connections or replace parts
as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the same type as origi-
nally equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing, cracks,
deterioration, and signs of leaking. Replace
any deteriorated or damaged parts immedi-
ately.
Brake pads and rotors: Check for wear, de-
terioration and fluid leaks. Replace any dete-
riorated or damaged parts immediately.
Exhaust system: Visually inspect the exhaust
pipes, muffler and hangers for leaks, cracks,
deterioration, and damage. Tighten connec-
tions or replace parts as necessary.
In-cabin microfilter: Replace at specified in-
tervals. When driving for prolonged periods in
dusty conditions, replace the filter more fre-
quently. Propeller shaft(s):

ness, and grease leakage. (AWD)
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots: Check for dam-
age, looseness, and leakage of oil or grease.
Under severe driving conditions, inspect more
frequently.
Tire rotation: Tires should be rotated every
7,500 miles (12,000 km) according to the
instructions under “Explanation of general
maintenance items” in this section. When ro-
tating tires, check for damage and uneven
wear. Replace if necessary.
Transmission fluid/oil, differential oil and
transfer case oil: Visually inspect for signs of
leakage at specified intervals.
Replace at specified intervals.
9-6Maintenance and schedules

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, refer to "Recom-
mended fluids/lubricants and capacities" in
this section. 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

∙ Always secure items in the trailer to pre-vent load shift while driving.
∙ Keep the cargo load as low as possible in the trailer to keep the trailer center of
gravity low.
∙ Load the trailer so approximately 60% of the trailer load is in the front half and
40% is in the back half. Also make sure
the load is balanced side to side.
∙ Check your hitch, trailer tire pressure, ve- hicle tire pressure, trailer light operation,
and trailer wheel lug nuts every time you
attach a trailer to the vehicle.
∙ Be certain your rearview mirrors conform to all federal, state or local regulations. If
not, install any mirrors required for tow-
ing before driving the vehicle.
∙ Determine the overall height of the ve- hicle and trailer so the required clearance
is known.Trailer towing tips
In order to gain skill and an understanding of
the vehicle’s behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability
and braking performance will be somewhat
different than under normal driving condi-
tions.
∙ Always secure items in the trailer to pre- vent load shift while driving.
∙ Lock the trailer hitch coupler with a pin or lock 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 back-
ing 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 move the shift selector to 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 downhill 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. Shift the transmission into P (Park).
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.
Technical and consumer information10-27

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 sec-
onds, 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 EDR. The
main purpose of an EDR is to record, in cer-
tain collision or near collision-like situations,
such as an air bag deployment or hitting a
road obstacle, data that will assist in under-
standing how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems 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 depress- ing 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 colli-
sions and injuries occur. NOTE: EDR data are
recorded by your vehicle only if a nontrivial
collision situation occurs; no data are re-
corded by the EDR under normal driving con-
ditions and no personal data (e.g. name, gen-
der, age and collision location) are recorded.
However, other parties, such as law enforce-
ment, could combine the EDR data with the
type of personally identifying data routinely
acquired during a collision investigation.
To read data recorded by an EDR, special
equipment is required and access to the ve-
hicle or the EDR is needed. In addition to the
vehicle manufacturer and INFINITI retailer,
other parties, such as law enforcement, that
have the special equipment, can read the in-
formation if they have access to the vehicle or
the EDR. EDR data will only be accessed with
the consent of the vehicle owner or lessee or
as otherwise required or permitted by law.
