2021 NISSAN GT-R transmission

Do not use the cruise control when
driving under the following condi-
tions. Doing so could cause a loss of
vehicle control and result in an acci-
dent.
.When it is not possible to keep
the vehicle at a set speed.
. In heavy traffic or in traffic that
varies in speed.
. On winding or hilly roads.
. On slippery roads (rain, snow, ice,
etc.).
. In very windy areas.
NOTE:
. When the SAVE mode is selected
with the transmission setup switch,
the acceleration and deceleration
can be controlled smoothly. When
the SAVE mode is selected, the
maximum setting speed is lower
than the one in the normal mode. When the vehicle approaches a gen-
tle uphill, there may be a slight delay
as the vehicle returns to the preset
speed. However, the vehicle will
gradually accelerate and return to
the preset speed.
PRECAUTIONS ON CRUISE CON-
TROL.
If the cruise control system malfunc-
tions, it will cancel automatically. The
SET indicator will blink and the cruise
control system warning will appear to
warn the driver. (
“Cruise control
system warning” page 2-43)
. If the engine coolant temperature
becomes excessively high, the cruise
control system will be canceled auto-
matically.
. If the SET indicator blinks, turn the
cruise control main switch off and it is
recommended you contact a GT-R

CRUISE CONTROL

NOTICE
When the vehicle is stopped on a hill,
do not hold the vehicle in place by
depressing the accelerator pedal.
Doing so may cause the clutch to
overheat and result in transmission
damage. Use the brakes to prevent
the vehicle from moving.
The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the
brake pedal and apply the accelerator
when the vehicle is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
. The shift lever is moved to a forward
or reverse position.
. The vehicle is stopped completely on a
hill by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to
roll back and hill start assist will stop operating completely.
Hill start assist will not operate when the
shift lever is moved to the
or
position
or on a flat and level road.
NOTE:
This system does not function when the
Vehicle Dynamic Control VDC) system
warning appears on the vehicle infor-
mation display located in the tach-
ometer. (

TIGHT CORNER BRAKING PHE-
NOMENONIf the steering wheel is turned more than
half a turn when the vehicle is started
when it is cold, it may be harder to move
the vehicle forward and backward. This
phenomenon is known as the “tight
corner braking phenomenon”.
This phenomenon is unique to AWD
vehicles, and occurs due to a difference
in speeds between the front and rear
wheels while the vehicle is turning. This
does not indicate that there is a malfunc-
tion.
NOTE:
If the tight corner braking phenomenon
occurs, a slipping sound may be heard
from the tires, or a squeaking sound
may be heard from the drive system.Reducing tight corner braking
phenomenonThe tight corner braking phenomenon
can be reduced if the following three
conditions are met:
.Transmission setup switch is set to
Normal mode.
. Vehicle speed is low (less than ap-
proximately 6 MPH (10 km/h)). .
The steering wheel is turned more
than 1/2 turn.
TIRESThis vehicle is equipped with special tires.
When changing the tires, install the de-
signated special tires. Replacing tires as a
set of four with new ones is recom-
mended. However, if a tire is punctured
or damaged, it may be possible to replace
only the damaged tire. Determining
whether one tire or a complete set of
tires should be replaced is based on a
number of factors including tire wear and
condition. Contact your GT-R certified
NISSAN dealer. They can recommend if
an individual tire or a complete set should
be replaced.
NOTICE
If tires other than the designated
tires, tires with large differences in
wear or tires of different sizes are
installed, the AWD performance will
be degraded and the drive mechan-
ism may be damaged.
AWD SYSTEM CHARACTERISTICSThe AWD system automatically distri-
butes the optimal torque to the front
and rear wheels. This provides both the
superior turning performance of a rear
wheel drive vehicle and the traction of a
AWD vehicle.
Electronic control continuously distri-
butes torque to the front and rear wheels
in the range from 0:100 (rear-wheel drive
mode) to 50:50 (all-wheel drive mode) to
match the driving conditions and road
conditions. This allows the engine output
(torque) to be effectively transmitted to
the road surface.

WARNING
.Prolonged and repeated contact
with used engine oil may cause
skin cancer.
. Try to avoid direct skin contact
with used oil. If skin contact is
made, wash thoroughly with soap
or hand cleaner as soon as pos- sible.
. Keep used engine oil out of reach
of children. NOTE:
When checking or replacement is re-
quired, it is recommended you contact
a GT-R certified NISSAN dealer for servi-
cing.
NOTICE
.
It is recommended that you use
only Genuine NISSAN Transmis-
sion Oil R35 Special or equivalent.
Do not mix with other fluids.
. Using transmission oil other than
Genuine NISSAN Transmission Oil
R35 Special or equivalent may
cause deterioration in driveability
and transmission durability, and
may damage the transmission.

garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
. Always use tires of the specified
type, size, brand, construction
(bias, bias-belted, radial or run-
flat), and tread pattern on all four
wheels. Failure to do so may
result in a circumference differ-
ence between tires on the front
and rear axles which will cause
excessive tire wear and may da-
mage the transmission, transfer
case and differential gears.
Wheel balanceUnbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance.
Therefore, they should be balanced as
required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the rear wheels on the
vehicle could lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information” (Canada) in the Warranty Information
Booklet.

JACKING VEHICLE AND REMOVING
WHEELS
WARNING
.
Make sure the parking brake is
securely applied and the trans-
mission is shifted into the
position.
. Never change tires when the ve-
hicle is on a slope, ice or slippery
areas. This is hazardous.
. Never change tires if oncoming
traffic is close to your vehicle.
Wait for professional road assis-
tance.
Blocking wheelsPlace suitable blocks
at both the front
and back of the wheel diagonally oppo-
site the flat tire to prevent the vehicle
from moving when it is jacked up.

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.
