NISSAN GT-R 2021 Owners Manual

For models without NCCB (NISSAN Car-
bon Ceramic Brake) package:
NISSAN generally recommends to replace
all four sets of brake pads and disc rotors
at the same time to maintain maximum
brake performance.However, replacing only the brake pads
may be allowed in some cases (four
wheels or only front wheels depending
on the conditions). A GT-R certified tech-
nician must inspect the vehicle and
determine that only the brake pads need
to be replaced. In this case, replacing all
brake pads and disc rotors as a set is not
necessary.
Note that the replacement of brake pads
and the disc rotors as a set on all four
wheels should be performed when a GT-R
certified technician determines that this
is the correct repair.
If the inside of the disc rotors are cold
during the winter and the surface be-
comes hot due to a heavy force being
applied repeatedly to the brakes, cracks
may occur near the coolant hole on the
surface of the disc rotor. Cracks may also
occur due to a heavy force being repeat-
edly applied to the brakes during high
performance driving. In these cases it
may be necessary to replace the disc
rotors or brake pads depending on the
condition of the crack. We recommend
contacting a GT-R certified NISSAN dealer
for replacement.
NCCB (NISSAN Carbon Ceramic
Brake) (if so equipped)Replacement of brake pads and
disc rotorsWhen replacing brake pads and brake
disc rotors, NISSAN recommends repla-
cing two sets of them at the same time.

However, the brake pads can be sepa-
rately replaced only when a GT-R certified
technician judges that the brake disc
rotors are reusable, based on a measured
weight and a check for scratches and
cracks.EXHAUST MUFFLER AND TRUNK
CARPETThe GT-R exhaust system is designed to
provide the maximum vehicle perfor-
mance and to protect the vehicle from
high exhaust gas temperatures.
If non-genuine GT-R exhaust system
parts are used it is possible that the
muffler or other exhaust system parts will
deform and cause damage to the under-
body. Non-genuine GT-R exhaust system
parts can also affect vehicle performance
and possibly lead to turbocharger, engine
or power train related parts including
transmission, damage.
Also, do not remove the trunk carpet from
the vehicle for any reason. The carpet
insulates the vehicle interior from the
heat of the muffler and from the noise
of the transmission.
TITANIUM MUFFLER AND TRUNK
CARPET (if so equipped)
NOTICE
Never allow polishes with com-
pounds, because there is a possibi-
lity that the titanium muffler finisher
coloring will be changed.

position.
. Transmission oil temperature is 284°F
(140°C) or higher:
If the transmission oil temperature
increases to over 284°F (140°C), the
color of the meter display changes to
red. However, the vehicle can continue
to be driven until the temperature
reaches 295°F (146°C). If the oil tem-
perature exceeds 284°F (140°C) while
driving (the color of the meter dis-
played in red), change both the trans-
mission oil and the differential oil after
driving because these fluids have
deteriorated because of the heat.

ADDITIONAL MAINTENANCE ITEMS

Cool downThe information and specifications in
this section apply only when engaging
in performance driving.
Cool down the vehicle to help extend the
life of the vehicle if coolant temperatures
are extremely high. Drive the vehicle at 37
to 50 MPH (60 to 80 km/h), in 5th or 6th
gear for 2 to 3 miles (3 to 5 km) and then
stop the engine.Refueling precautions
WARNING
Do not attempt to top off the fuel
tank after the fuel pump nozzle
shuts off automatically. Continued
refueling may cause fuel overflow,
resulting in fuel spray and possibly a
fire. The fuel tank is full at the first
automatic shutoff.
To maximize vehicle performance, the
fuel tank is located as low as possible to
lower the vehicle center of gravity. The
tank is also divided into two parts. This
fuel tank design causes higher pressures
inside the tank than other vehicles so fuel
spillage is possible by trying to top off the fuel tank after automatic shutoff.
The fuel tank pressure is higher when the
vehicle is hot, especially if the tank is more
than half full. If the cap is opened when
the vehicle is hot, it may cause fuel spray
and there may be a hissing noise. Open
the cap slowly, releasing the pressure
from the tank gradually. Also, if the
vehicle is refueled when the vehicle is
hot, the fuel pump may automatically
shut off before the tank is full. This does
not indicate that there is a malfunction.
Refuel slowly or refuel after the vehicle
has cooled.
INSPECTION AND ADJUSTMENTS
BEFORE DRIVINGThe information and specifications in
this section apply only when engaging
in performance driving.Fluids.
Check the engine, transmission, differ-
ential and under vehicle surfaces for
oil and coolant leaks.
. Check the fluid levels and adjust as
necessary using the specified fluid as
described under the conditions listed
in this section.(
“Recommended
fluids and maintenance interval” page GTR-20) If you do not drive under the
conditions listed, refer to the “9. Main-
tenance and schedules” section of this
manual.

to be 0.39 in (10
mm) (1/8 gal (0.5 liters))
below the H
mark on the engine oil dipstick. (
range is 1.18 in (30 mm).) Before
checking the oil level, run the engine
until it reaches operating temperature
and wait at least 5 minutes after
turning off the engine. Make sure the
oil level always remains above the L
mark.
When the vehicle is delivered, the
engine oil is set to
