mileage INFINITI QX30 2018 Owners Manual

INFINITI retailer for this service. See "Precau-
tions when starting and driving" in the "5.
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 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 connec-
tions.Underbody:
The underbody is frequently exposed to cor-
rosive 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
accumulate. For additional information, see
"Cleaning exterior" in the "7. Appearance and
care" section.
Windshield washer fluid*:
Check that there is adequate fluid in the res-
ervoir.
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. 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 warran-
ties 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
Chapter 8.
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.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Maintenance and Schedules9-5

Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (4WD/AWD).
Steering gear and linkage, axle and suspen-
sion 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 5,000 miles
(8,000 km) according to the instructions un-
der "Tire rotation*" earlier in this section.
When rotating tires, check for damage and
uneven wear. Replace if necessary.
Transmission fluid/oil, differential oil,
transfer case oil:
Visually inspect for signs of leakage at speci-
fied intervals.To ensure smooth, trouble-free, safe and
economical driving, INFINITI provides two
maintenance 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 odometer 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 sched-
ule.
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 op-
erating conditions; should be performed on
vehicles that are driven under especially de-
manding conditions. Additional maintenance
items should be performed if you primarily
operate your vehicle under the following con-
ditions:
•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 stan-
dard and severe maintenance items should
be performed at every interval.

does not show any information on the engine
oil level.
