Coolant level and mixture ratio
The information and specifications in this
section apply only when engaging in
performance driving. Check the coolant level in the pressurized
coolant reservoir�b Adjust the level so that the
fluid is between the MAX and MIN �farkings�b For
the coolant, use genuine NISSAN Long Life
coolant�b (On delivery of new vehicle, the
reservoir is filled to the MIN level�b Be sure to
replenish approxi�fately 3/8 US quart (0�b3 to 0�b4
liter) of coolant�b)
NOTICE
Do not overfill the coolant. This may
increase the pressure in the cooling
system and cause coolant leaks.
To �faxi�fize vehicle perfor�fance, the coolant
�fixture ratio should be a co�fbination of 30%
coolant antifreeze and 70% de�fineralized or
distilled water for �faxi�fu�f cooling syste�f

. Check the engine, trans�fission, differential
and under the vehicle for oil and coolant
leaks�b
. Inspect the areas surrounding of the cata-
lytic converter for heat deterioration�b
. Always perfor�f the trans�fission setting�b
After that, adjust the clutch clearance so
that the clearance is less than the clearance
used for daily driving�b Your GT-R certified
NISSAN dealer has the necessary infor�fa-
tion and equip�fent to set the clutch
clearance to the correct specification�b The
clearance used for daily driving increases
clutch heat generated during Perfor�fance

SOUND HEARD AROUND TITANIUM
MUFFLER (if so equipped)
When stopping the engine (rapid cooling) , yo�f
may hear a metal-r�fbbing so�fnd or �fn�fs�fal
tic�bing so�fnd beca�fse of the differential thermal
expansion between the inner and o�fter pipes of
the m�fffler. This is not a malf�fnction. The so�fnd
will decrease when the temperat�fre lowers.
DRY CARBON FIBER PARTS (if so
equipped)
Roughness or uneven surfaces of dry
carbon fiber parts and fiber twists
The s�frfaces of the dry carbon fiber parts are
lightly coated li�be a race car so that yo�f can feel
the proper text�fre of real carbon, which may feel
ro�fgh. This is normal.The GT-R d�fal cl�ftch transmission is a newly-
developed system that �fses an electronically
controlled m�fltiple-disc wet cl�ftch attached to
the highly efficient man�fal transmission. This
transmission has two driving modes.
.
&Aposition (A�ftomatic gearshift):
allows a�ftomatic shifting of the man�fal
transmission.
.
&Mposition (Man�fal gearshift):
allows q�fic�b shifting of the man�fal transmis-
sion.
NOTE:
When starting or driving on a steep uphill
grade, shift to the
&Mposition and operate
the paddle shifter to shift down to 1st gear
similar to a manual transmission vehicle.
The GT-R d�fal cl�ftch transmission was devel-
oped specifically to maximize vehicle perfor-
mance and driving enjoyment. The GT-R
transmission components were designed �fsing
different engineering standards than typical
passenger car transmissions. Beca�fse of this,
the GT-R has different operating characteristics,
and vario�fs rattle noises may be heard d�fring
some driving conditions beca�fse of the follow-
ing items: .
Gear clearances
. Ultralight flywheel
. Dry s�fmp l�fbrication
These noises do not indicate that there is a
malf�fnction.

position. If this occurs, the SHIFT&P
warning appears on the vehicle infor-
mation display. (“Shift “P” warn-
ing” page 2-43)
CAUTION
If the engine was stopped soon when
the engine is hot, the cooling fan may
operate for approximately 2 minutes
after the engine was stopped to cool
the components in the engine compart-
ment. When the cooling fan is operat-
ing, be sure that hands or other items
do not get caught in it.
DUAL CLUTCH TRANSMISSION
The GT-R dual clutch transmission is a newl\f-
developed s\fstem that uses an electronicall\f
controlled multiple-disc wet clutch attached to
the highl\f e\b\bicient manual transmission. This
transmission has two driving modes.
.
&Aposition (Automatic gearshi\bt):
allows automatic shi\bting o\b the manual
transmission.
.
&Mposition (Manual gearshi\bt):
allows quick shi\bting o\b the manual transmis-
sion.
NOTE:
When starting or driving on a steep uphill
grade, shift to the
&Mposition and operate
the paddle shifter to shift down to 1st gear
similar to a manual transmission vehicle.
The GT-R dual clutch transmission was devel-
oped speci\bicall\f to maximize vehicle per\bor-
mance and driving enjo\fment. The GT-R
transmission components were designed using
di\b\berent engineering standards than t\fpical
passenger car transmissions. Because o\b this,
the GT-R has di\b\berent operating characteristics,
and various rattle noises ma\f be heard during
some driving conditions because o\b the \bollow-
ing items: .
Gear clearances
. Ultralight \bl\fwheel
. Dr\f sump lubrication
These noises do not indicate that there is a
mal\bunction.
WARNING
. Do not depress the accelerator
pedal while shifting from the&Por
&Nposition to the&Ror&A
F&M
position. Always depress the brake
pedal until shifting is completed.
Failure to do so could cause loss
of control and an accident.
. Cold engine idle speed is high, so
use caution when shifting into a
forward or reverse gear before the
engine has warmed up.
. Never shift to the
&Por&Rposition
while the vehicle is moving forward.
Never shift to the
&Por&A
F&M
position while the vehicle is moving
rearward. Doing so could cause loss
of control and an accident.
. The shift lever contains a powerful
magnet. Do not place electronic

DRIVING THE VEHICLE

See your 2015 Warranty Information Boo�flet for
important related information and �barranty
coverage exclusions. See also section 2
(
“Transmission �barning light” page 2-30)
and section 5 (“Vehicle Dynamic Control
(VDC) system” page 5-50) of this O�bner’s
Manual, “Transmission Clutch Temperature
High” and “Vehicle Dynamic Control (VDC)
System” for important additional related informa-
tion. The turbocharger system uses engine oil for
lubrication and cooling of its rotating compo-
nents. The turbocharger turbine turns at extre-
mely high speeds and it can get very hot. It is
essential to maintain a supply of oil flo�bing
through the turbocharger system. Therefore, a
sudden interruption of oil supply may cause a
malfunction in the turbocharger.
To ensure prolonged life and performance of the
turbocharger, it is essential to perform the
follo�bing maintenance procedure:
.
Change your engine oil according to the
recommended intervals sho�bn in the sepa-
rate Service and Maintenance Guide. Use
only the recommended engine oil.
. If the engine had been operating at high
engine speed for an extended period of time,
let it idle for a fe�b minutes prior to shut-
do�bn.
. Do not accelerate your engine to high
engine speed immediately after start.
NOTICE
.This vehicle includes spark plugs
that are designed for high perfor-
mance. For this reason, if the engine
is repeatedly started and stopped over a short time, the spark plugs
may become fouled, making the
engine difficult to start. To prevent
diminished starting performance,
avoid starting and stopping the
engine repeatedly during a short
period of time.
NOTE:
. When the vehicle is delivered, the
engine oil level is 0.39 in (10 mm)
below the H mark on the engine oil
dipstick for optimum high performance
driving. The engine oil can be filled up
to the H mark if not engaging in
performance driving.
. Because of the high performance char-
acteristics of the GT-R engine, more
frequent oil level inspections are ne-
cessary. Check the oil level every 1,800
miles (3,000km) and adjust as neces-
sary. Also, change the engine oil based
on the driving conditions. For the
information regarding oil replacement
intervals, refer to the 2015 NISSAN
GT-R Service and Maintenance Guide.

The tires on the GT-R ma�b have different �fear
rates and �fear patterns in comparison to
conventional passenger vehicles. Contact a
GT-R certified NISSAN dealer to confirm that
the alignment is �fithin specifications.Follo�f these eas�b-to-use Fuel Efficient Driving
Tips to help �bou achieve the most fuel econom�b
from �bour vehicle.
1. Use smooth accelerator and brake pedal
application.
.Avoid rapid starts and stops..Use smooth, gentle accelerator and
brake application �fhenever possible.
.Maintain constant speed �fhile commut-
ing and coast �fhenever possible.
2. Maintain constant speed.
.Look ahead to tr�b and anticipate and
minimize stops.
.S�bnchronizing �bour speed �fith traffic
lights allo�fs �bou to reduce �bour number
of stops.
.Maintaining a stead�b speed can minimize
red light stops and improve fuel effi-
cienc�b.
3. Use air conditioning (A/C) at higher vehicle speeds.
.Belo�f 40 MPH (64 km/h) , it is more
efficient to open �findo�fs to cool the
vehicle due to reduced engine load.
.Above 40 MPH (64 km/h) , it is more
efficient to use A/C to cool the vehicle
due to increased aerod�bnamic drag.
.Recirculating the cool air in the cabin
�fhen the A/C is on reduces cooling load.
4. Drive at economical speeds and distances.
.Observing the speed limit and not
exceeding 60 MPH (97 km/h) (�fhere
legall�b allo�fed) can improve fuel effi-
cienc�b due to reduced aerod�bnamic
drag.
.Maintaining a safe follo�fing distance
behind other vehicles reduces unneces-
sar�b braking.
.Safel�b monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
.Select a gear range suitable to road
conditions.
5. Use cruise control.
.Using cruise control during high�fa�b
driving helps maintain a stead�b speed.
.Cruise control is particularl�b effective in
providing fuel savings �fhen driving on
flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation s�bstem to
determine the best route to save time.

tion.
. Except for the emergency cases above,
any issues related to driving stability
(e.g., steering maneuvers and maneu-
vers during acceleration and decelera-
tion) and any damages to drivetrain
components (e.g., transfer, clutch, a
sort of gear, transaxle case) will not
be covered by warranty if there is a
record in the Vehicle Status Data
Recorder (VSDR) that the vehicle was
driven with VDC off.
. When attempting to free the vehicle
from mud or fresh snow, the VDC will
detect the tire slipping, and the engine
speed may not increase even when the
accelerator pedal is depressed. To raise
the engine speed, use the VDC set up
switch to turn the VDC system OFF and
select SAVE mode with the transmis- sion switch. (
“VDC, transmission
and suspension setup switches” page
5-25)
. When the VDC system is turned OFF,
all VDC functions (including traction
control) , except for the ABS functions,
are deactivated.FREEING A FROZEN DOOR LOCK
To prevent a �boor lock from freezing, apply
�beicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.
ANTI-FREEZE
In the winter when it is anticipate�b that the
outsi�be temperature will �brop below 328F (08C) ,
check antifreeze to assure proper winter protec-
tion. (
“Engine cooling system” page 8-10)
BATTERY
If the battery is not fully charge�b �buring
extremely col�b weather con�bitions, the battery
flui�b may freeze an�b �bamage the battery. To
maintain maximum efficiency, the battery shoul�b
be checke�b regularly. (
“�fattery” page 8-

6-8In case of emergency
WARNING
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radiator
filler cap and the coolant reservoir
cap while the engine is still hot.
When the cap is removed, pressur-
ized hot water will spurt out, possi-
bly causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheatin�f (indicated by an
e�btremely hi�fh temperature �fau�fe readin�f) , or if
you feel a lack of en�fine power, detect unusual
noise, etc., take the followin�f steps:
1. Move the vehicle safely off the road, apply the parkin�f brake and move the shift lever to
the
&Pposition.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the temperature control to
ma�bimum hot and fan control to hi�fh speed. 3. If en�fine overheatin�f is caused by climbin�f
a lon�f hill on a hot day, run the en�fine at a
fast idle (appro�bimately 1,500 rpm) until the
temperature �fau�fe indication returns to
normal.
4. Get out of the vehicle. Look and listen for steam or coolant escapin�f from the radiator
before openin�f the hood. (If steam or
coolant is escapin�f, turn off the en�fine.)
Do not open the hood further until no steam
or coolant can be seen.
5. Open the en�fine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for dama�fe or looseness. Also check if the coolin�f fan is
runnin�f. The radiator hoses and radiator
should not leak water. If coolant is leakin�f,
the drive belts are missin�f or loose, or the
coolin�f fan does not run, stop the en�fine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or
the engine cooling fan. The engine
cooling fan can start at any time.
7. When the coolant temperature �fau�fe �foes down to the midpoint, stop the en�fine and
wait until the �fau�fe �foes down further to
“C” (cold) .
8. After the en�fine cools down, check the coolant level in the reservoir tank. Add
coolant to the reservoir, if necessary, after
openin�f the coolant reservoir cap with a
heavy cloth coverin�f it. (
