you may not be able to shift gear
or it may take longer to shift gear.
Make sure to depress the brake
pedal and check that the vehicle
has stopped before shifting.
CAUTION
. Because the vehicle includes a
dual clutch transmission that
automatically controls the clutch
and shifting operation of the
manual transmission, whenever
the shift lever is in a position
other than
or
, the vehicle will
begin to move slowly, in the same
way as when the clutch in a
manual transmission vehicle is
partially engaged. Keep the brake
pedal firmly depressed when the vehicle is stopped. In some cir-
cumstances the vehicle may not
start moving on its own, however
this does not indicate that there
is a malfunction.
NOTICE
.
To avoid possible damage to your
vehicle; when stopping the vehi-
cle on an uphill grade, do not hold
the vehicle in place by depressing
the accelerator pedal. Doing so
may cause the clutch to overheat
and result in transmission da-
mage. Use the brakes to prevent
the vehicle from moving.
. The GT-R dual clutch transmis-
sion is provided with a dry sump
lubrication system that improves
efficiency and ensures reliability
under high g-force conditions.
When oil viscosity is high at low
temperatures, it takes longer for
all components to be sufficiently
lubricated. Thus, when the trans-
mission temperature is low (ap-
proximately 104°F (40°C), do not
accelerate rapidly or run the en-
gine faster than 4,000 rpm.

NOTICE
.When the temperature of the
engine coolant and transmission
oil is high or low, the function
cannot be used. The temperature
range in which the R mode start
function can be used:
— Engine coolant: 140°F - 212°F
(60°C - 100°C)
— Transmission oil: 140°F - 266°F (60°C - 130°C)
. If the R mode start function is
used 4 times consecutively, the
function may be disabled and
cannot be turned on to protect
the vehicle system. While the function is disabled, the warning
light illuminates. When the warn-
ing light illuminates, perform cool
down driving. (
“Cool down”
page GTR-14) When the warning
light turns off, the function can be
used again.
. The performance of start may
vary depending on the amount
of wheel spin ,or increase and
decrease of the engine output in
response to the outside tempera-
ture. (This vehicle was set up
according to the road surface
conditions of the straight sec-
tions of the Sendai Highland Ra-
ceway course in Japan at 59°F
(15°C).)
. For safety reasons, VDC control
may activate automatically when
driving on a slippery road surface,
such as a wet road, in order to
apply the brakes or limit the
engine output.
. Frequent use of the R mode start
function increases the load on
the powertrain related parts such
as the clutch and transmission
compared to normal driving. In
particular, the clutch will wear out

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
change intervals.Change intervals
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

. 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
