Inside the vehicleThe maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled mainte-
nance, 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.
Transmission
mechanism: On a fairly
steep hill, check that your vehicle is held
securely with the shift lever in the
position without applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, it is recommended you see

is used.
. Objects in the RearView Monitor
will appear visually opposite
compared to when viewed in the
rearview and outside mirrors.
. Use the displayed lines as a re-
ference. The lines are highly af-
fected by the number of
occupants, fuel level, vehicle po-
sition, road conditions and road
grade.
. Make sure that the trunk lid is
securely closed when backing up.
. Do not put anything on the rear-
view camera. The rearview cam-
era is installed above the license
plate.
. When washing the vehicle with
high-pressure water, be sure not
to spray it around the camera.
Otherwise, water may enter the
camera unit causing water con-
densation on the lens, a malfunc-
tion, fire or an electric shock.
. Do not strike the camera. It is a
precision instrument. Otherwise,
it may malfunction or cause da-
mage resulting in a fire or an
electric shock. The following are operating limitations
and do not represent a system malfunc-
tion:
.
When the temperature is extremely
high or low, the screen may not clearly
display objects.
. When strong light is directly coming
on the camera, objects may not be
displayed clearly.
. Vertical lines may be seen in objects
on the screen. This is due to strong
reflected light from the bumper.
. The screen may flicker under fluores-
cent light.
. The colors of objects on the RearView
Monitor may differ somewhat from
the actual color of objects.
. Objects on the monitor may not be
clear in a dark environment.
. There may be a delay when switching
to the RearView Monitor screen.
. If dirt, rain or snow accumulates on
the camera, the RearView Monitor
may not display objects clearly. Clean
the camera.
. Do not use wax on the camera win-
dow. Wipe off any wax with a clean
cloth dampened with mild detergent
diluted with water.
SYSTEM MAINTENANCE
CAUTION
.Do not use alcohol, benzine or
thinner to clean the camera. This
will cause discoloration. To clean
the camera, wipe with a cloth
dampened with diluted mild
cleaning agent and then wipe
with a dry cloth.
. Do not damage the camera as the
monitor screen may be adversely
affected.

system. Note that while some fuel pumps
label MMT content, not all do, so you may
have to consult your gasoline retailer for
more details.Aftermarket fuel additives
NOTICE
NISSAN does not recommend the use
of any aftermarket fuel additives
(Example: fuel injector cleaner, in-
take valve deposit removers, etc.)
which are sold commercially. Many
of these additives intended for gum,
varnish or deposit removal may con-
tain active solvent or similar ingre-
dients that can be harmful to the fuel
system and engine.Octane rating tipsUsing unleaded gasoline with an octane
rating lower than recommended above
can cause persistent, heavy spark
knock. (Spark knock is a metallic rap-
ping noise.) If severe, this can lead to
engine damage. If you detect a persis-
tent 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 levelroads, it is recommended you have a
GT-R certified NISSAN dealer correct the
condition. Failure to correct the condi-
tion is misuse of the vehicle, for which
NISSAN is not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This
in turn may cause excessive fuel con-
sumption or damage to the engine. If any
of the above symptoms are encountered,
it is recommended you have your vehicle
checked at a GT-R certified NISSAN dealer
or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no 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 RE-
COMMENDATION
Selecting the correct oilIt is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance.
(
“Capacities and recommended
fluids/lubricants” page 10-2)
Mobil 1 (0W-40) (100% synthetic) is the factory fill oil. The VR38 engine with its
plasma-sprayed bores was developed
using this oil. NISSAN cannot ensure
proper engine operation and durability if
other 0W-40 non-equivalent synthetic oil
is used. If Mobil 1 (0W-40) or equivalent is
not available, Mobil 1 (10W-40) (100%
synthetic) or equivalent may be used;
however, some performance loss may
be noticed.
NOTICE
Using an engine oil other than that
specified could adversely affect the
engine. See the 2021 NISSAN GT-R
Warranty Information Booklet for
details and exclusions.Oil additivesNISSAN 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 fol-
lowed.
Oil which may contain foreign matter or
has been previously used should not be
used.

position.
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing near the fan.
. The fuel filter or fuel lines should
be serviced by a GT-R certified
NISSAN dealer because the fuel
lines are under high pressure
even when the engine is off.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
NOTICE
.Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or trans-
mission related component har-
nesses disconnected while the
ignition switch is in the ON posi-
tion.

the steering wheel cannot be unlocked.
Do not move the vehicle with the steering
wheel locked.
NOTICE
If the shift lever cannot be moved
out of the
position after perform-
ing the shift lock release procedure,
it is recommended you immediately
have the vehicle inspected by a GT-R
certified NISSAN dealer.
Adaptive shift controlThe adaptive shift control system auto-
matically operates when the transmission
is in the
position and selects an
appropriate gear depending on the road
conditions such as uphill, downhill or
curving roads.Starting and driving
