2020 INFINITI Q50 oil temperature

9-6Maintenance and schedules
Brake pads, rotors, drums and linings:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or damaged
parts immediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deterioration,
and damage. Tighten connections or replace
parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
replace the filter more frequently.
Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (4WD/AWD/RWD)
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 condi-
tions, inspect more frequently.
Tire rotation:
Tires should be rotated every 5,000 miles
(8,000 km) according to the instructions
under “Explanation of general maintenance
items” (P.9-2). When rotating tires, check for
damage and uneven wear. Replace if neces-
sary.Transmission fluid/oil, differential oil and
transfer case oil:
Visually inspect for signs of leakage at
specified intervals.
To help ensure smooth, 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 peo-
ple, 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 schedule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the same
mileage/time intervals.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditions;
should be performed
on vehicles that are driven under especially
demanding conditions. Additional mainte-
nance items should be performed if you
primarily operate your vehicle under the
following conditions:
. Repeated short trips of less than 5 miles
(8 km).
. Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing.

Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is
important that the engine oil viscosity be
selected based on the temperatures at which
the vehicle will be operated before the next
oil change. Choosing an oil viscosity other
than that recommended could cause serious
engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, use the genuine 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. Oil and filter other
than the specified quality, or oil and filter
change intervals longer than recommended
could reduce engine life. Damage to engines
caused by improper maintenance or use of
incorrect oil and filter quality and/or vis-
cosity is not covered by the new INFINITI
vehicle limited warranties.
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.
AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioning system in your INFINITI
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
NISSAN A/C system oil PAG or the exact
equivalents.
CAUTION
The use of any other refrigerant or
lubricant may cause severe damage to
the air conditioning system and may
require the replacement of all air condi-
tioner system components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
governmental regulations require the recov-
ery and recycling of any refrigerant during
automotive air conditioning system service. Your INFINITI retailer has the trained tech-
nicians and equipment needed to recover
and recycle your air conditioning system
refrigerant.
It is recommended you visit an INFINITI
retailer when servicing your air conditioning
system.
