. 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.

MAINTENANCE PRECAUTIONS
. If the oil level is below
,
remove the oil filler cap and pour
recommended oil through the open- ing.
Do not overfill
.
6. Recheck oil level with the dipstick.
NOTE:
. It is normal to add some oil between
oil maintenance intervals or during
the break-in period, depending on
the severity of operating conditions.
More engine oil is consumed by
frequent acceleration/deceleration
especially when the engine rpm is
high. If your rate of oil consumption
increases suddenly or without ex-
planation, NISSAN recommends that
you have your vehicle inspected by a
GT-R certified NISSAN dealer.
. When the vehicle is delivered, the
engine oil is set to 0.39 in (10 mm)
below the H mark for optimal high
performance driving. The engine oil
can be filled up to the H mark if
performance driving is not engaged.

OPENING AND CLOSING THE
TRUNKWhen opening the trunk, first unlock it
then lift up the trunk lid so that it is fully
open.
When closing the trunk, lower the trunk
lid and press it until it is securely locked in
place. The strap
(except for carbon
trunk lid models) or the handle
(for
carbon trunk lid models) can be used
when the trunk lid is dirty.
NOTICE
. Open and close the trunk without
grasping the rear spoiler. Grasp-
ing the rear spoiler to open or
close the trunk may damage the
spoiler.
. Do not leave the key inside the
trunk.
NOTE:
. To prevent the Intelligent Key from
being accidentally locked in the
trunk, lockout protection is
equipped with the Intelligent Key
system. When the trunk lid is closed
with the Intelligent Key inside the
trunk, the outside buzzer will sound and the trunk will open.
. The trunk of this vehicle is slightly
more difficult to close than an or-
dinary vehicle (particularly when the
vehicle is new). This is because the
trunk rigidity has been increased to
handle the high load on the rear
spoiler during vehicle operation.
This does not indicate that there is
a malfunction. Check that the trunk
is securely locked.
EMERGENCY TRUNK LID RELEASE
WARNING
Closely supervise children when they
are around cars to prevent them
from playing and becoming locked
in the trunk where they could be
seriously injured. Keep the car
locked, with the trunk lid securely
latched, when not in use, and pre-
vent children’s access to Intelligent
Keys.
The emergency trunk lid release mechan-
until the lock
releases and push up on the trunk lid.
The release lever is made of a material
that glows in the dark after a brief
exposure to ambient light.
The handle is located on the back of the
trunk lid as illustrated.
2. Insert the mechanical key into the
emergency trunk lid opener and turn
it clockwise until it stops.
NOTE:
Because the trunk rigidity has been
increased to handle the high load on
the rear spoiler during vehicle opera-
tion, more force is required to operate
the mechanical key (particularly when
the vehicle is new). Be sure to turn the
key clockwise until it stops.Pre-driving checks and adjustments

However, the transmission may shift more slowly when the engine speed is low.
Mechanical Limited Slip
Differential (LSD) If the vehicle accelerates from a stop with the steering wheel turned half a turn in cold temperatures, the inner wheel tire
may slip and some noise or vibration may be heard. This phenomenon occurs because the viscosity of the differential oil
becomes thicker and the Limited Slip Differential (LSD) operates with increasing load. When the steering wheel is returned
to the straight ahead position or the differential oil warms up, the noise and vibration decrease.
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.
Oil viscosityThe engine oil viscosity or thickness
changes with temperature. Because of
this, it is important that the engine oil
viscosity be selected based on the tem-
peratures at which the vehicle will be
operated before the next oil change.
Choosing an oil viscosity other than that
recommended could cause serious en-
gine damage.Selecting the correct oil filterYour new vehicle is equipped with a high-
quality genuine NISSAN oil filter. NISSAN
recommends to use the genuine NISSAN
oil filter for the reason described in

AIR CONDITIONING SYSTEM RE-
FRIGERANT AND OIL RECOMMEN-
DATIONSThe air conditioner system in your
NISSAN vehicle must be charged with
the refrigerant HFO-1234yf (R-1234yf)
and NISSAN A/C System Oil VC100YF
(PAG) or the exact equivalents.
CAUTION
The use of any other refrigerant or oil
will cause severe damage to the air
conditioning system and will require
the replacement of all air conditioner
system components.
The refrigerant HFO-1234yf (R-1234yf) in
your NISSAN vehicle does not harm the
earth’s ozone layer. Although this refrig-
erant does not affect the earth’s atmo-
sphere, certain government regulations
require the recovery and recycling of any
refrigerant during automotive air condi-
tioner system service. Air conditioner
system should only be serviced by trained
and certified technicians to ensure proper
and safe operation (SAE J2845). Your GT-R
certified NISSAN dealer has the trained
technicians and equipment needed to
recover and recycle your air conditioner
system refrigerant. Only new and
SAEJ2842 certified evaporator(s) shall be
used as replacement parts.
A damaged or leaking air conditioning
evaporator shall never be repaired or
replaced with one removed from a used
or salvaged vehicle. To replace a da-
maged or leaking evaporator, use only
new and SAE J2842 certified evaporator
