maintenance INFINITI QX30 2017 Service Manual

Parking brake*:
Check the parking brake operation regularly.
Also make sure that the vehicle is held securely
on a fairly steep hill when only the parking
brake is applied. If the parking brake needs
adjustment, it is recommended you visit an
INFINITI retailer for this service.
Seats
:
Check seat position controls such as seat ad-
justers, seatback recliner, etc. to ensure they
operate smoothly and that all latches lock
securely in every position. Check that the head
restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Seat belts
:
Check that all parts of the seat belt system (for
example, buckles, anchors, adjusters and re-
tractors) operate properly and smoothly, and
are installed securely. Check the belt webbing
for cuts, fraying, wear or damage.
Steering wheel
:
Check for changes in the steering condition,
such as excessive free play, hard steering or
strange noises.Warning lights and chimes
:
Make sure that all warning lights and chimes
are operating properly.
Windshield defroster
:
Check that the air comes out of the defroster
outlets properly and in good 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*
:
Except for maintenance free battery, check the
fluid level in each cell. It should be between the
“UPPER” and “LOWER” lines. Vehicles operated
in high temperatures or under severe condi-
tions require frequent checks of the battery
fluid level.
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 ac-
cessories 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.
Coolant level*
:
Check the coolant level when the engine is cold.
Engine drive belt(s)*
:
Make sure that no belt is 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.
9-4Maintenance and Schedules

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 in-
spected. It is recommended you visit an INFINITI
retailer for this service. SeePrecautions when
starting and driving in the5. Starting and
driving section.
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 gasoline fumes are evi-
dent, 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 accu-
mulated. Make sure the hoses have no cracks,
deformation, rot or loose connections. Underbody
:
The underbody is frequently exposed to corro-
sive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust will
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 accumu-
late. For additional information, see
Cleaning
exterior in the7. Appearance and care sec-
tion.
Windshield washer fluid*
:
Check that there is adequate fluid in the reser-
voir. The following descriptions are provided to give
you a better understanding of the scheduled
maintenance items that should be regularly
checked or replaced. The maintenance schedule
indicates at which mileage/time intervals each
item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer to
General maintenance
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 warranties which
come with your vehicle. Other maintenance
items and intervals are required.
When applicable, additional information can be
found in the “Do-it-yourself” section in Chap-
ter 8.
NOTE
INFINITI does not advocate the use of non-OEM
approved aftermarket flushing systems and
strongly advises against performing these ser-
vices on an INFINITI product. Many of the after-
market flushing systems use non-OEM approved
chemicals or solvents, the use of which has not
been validated by INFINITI.

9-6Maintenance and Schedules

Steering gear and linkage, axle and suspension
parts, drive shaft boots:
Check for damage, looseness, and leakage of
oil or grease. Under severe driving conditions,
inspect more frequently
Tire rotation:
Tires should be rotated every 6,000 miles
(10,000 km) for 2WD, every 3000 miles (5000
km) for 4WD/AWD according to the instructions
underTire rotation* earlier in this section“Ge-
neral maintenance” in this section. When rotat-
ing tires, check for damage and uneven wear.

nomical driving, INFINITI provides two mainte-
nance schedules that may be used, depending
upon the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 120,000 miles (192,000
km)/144 months. For most people, the odom-
eter reading will indicate when service is
needed. However, if you drive very little, your
vehicle should be serviced at the regular time
intervals shown in the schedule.
After 120,000 miles (192,000 km)/144 months,
continue maintenance at the same mileage/time
intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING SYSTEMS
Additional maintenance items for severe oper-
ating conditions; should be performed on ve-
hicles that are driven under especially demand-
ing conditions. Additional maintenance items
should be performed if you primarily operate
your vehicle under the following conditions:
•Repeated short trips of less than 5 miles in
normal temperatures or less than 10 miles in
freezing temperatures.
•Stop-and-go traffic in hot weather or low
speed driving for long distances.
•Driving in dusty conditions or on rough,
muddy or salt-spread roads.
•Towing a trailer, or using a camper or car-top
carrier.
OIL CHANGE MONITOR
This vehicle is equipped with oil change moni-
tor. It calculates engine oil and filter change
interval base on driving conditions. Driving in
severe conditions will shorten the engine oil
and filter change interval. When the Engine Oil
– Service Due Now warning appears in the
vehicle information display, the engine oil and
filter need to be replaced.
NOTE
For vehicles operated in Canada, both standard
and severe maintenance items should be per-
formed at every interval.
MAINTENANCE SERVICE MESSAGES
The maintenance service interval display in-
forms you of the next service due date.
NOTE
The maintenance service interval display does
not show any information on the engine oil level.
MAINTENANCE SCHEDULES
Maintenance and Schedules9-7

The vehicle information display shows a service
message for a few seconds, e g:
•[Service A In .. days]
•[Service A Due]
•[Service A Exceeded by .. days]
Depending on the operating conditions of the
vehicle, the remaining time or distance until the
next service due date is displayed.
The letter indicates which service is due. A
stands for a minor service and B for a major
service. A number or another letter may be
displayed after the letter.
Only for certain countries: the position after the
letter A or B indicates any necessary additional
maintenance work. If you notify an INFINITI
retailer of this display, you will receive a state-
ment on the associated costs.
The maintenance service interval display does
not take into account any periods of time during
which the battery is disconnected.
Maintaining the time-dependent service sched-

corrected at an INFINITI retailer.
Have service work carried out as described in
the Maintenance Schedule. This may other-
wise lead to increased wear and damage to the
major assemblies or the vehicle. An INFINITI retailer will reset the maintenance
service interval display after the service work
has been carried out. You can also obtain
further information on maintenance work, for
example.
Special service requirements
:
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions or
increased loads, for example:
•Regular city driving with frequent intermedi-
ate stops
•If the vehicle is primarily used to travel short
distance
•For frequent operation in mountainous ter-
rain or on poor road surfaces
•If the engine is often left idling for long
periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil
filter changed more frequently. The tires must
be checked more frequently if the vehicle is
operated under increased loads. Further infor-
mation can be obtained at an INFINITI retailer.
9-8Maintenance and Schedules

The following tables show the standard maintenance schedule. Depending upon weather and atmospheric conditions, varying road surfaces, individual
driving habits and vehicle usage, additional or more frequent maintenance may be required. After 120,000 miles (192,000 km)/144 months, continue
