WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials
away from the exhaust system com-
ponents.
. Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
NOTICE
.Do not use leaded gasoline. Depos-
its from leaded gasoline seriously
reduce the three-way catalyst’s abil-
ity to help reduce exhaust pollu-
tants.
. Keep your engine tuned up. Mal-
functions in the ignition, fuel injec-
tion, or electrical systems can cause
overrich fuel flow into the three-way
catalyst, causing it to overheat. Do
not keep driving if the engine mis-
fires, or if noticeable loss of perfor-
mance or other unusual operating conditions are detected. Have the
vehicle inspected promptly by a
GT-R certified NISSAN dealer.
. Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, dama-
ging the three-way catalyst.
. Do not race the engine while warm-
ing it up.
. Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire should be checked mo�fthly whe�f cold
a�fd i�fflated to the i�fflatio�f �bressure recom-
me�fded by the vehicle ma�fufacturer o�f the
vehicle �blacard or tire i�fflatio�f �bressure label. (If
your vehicle has tires of a differe�ft size tha�f the
size i�fdicated o�f the vehicle �blacard or tire
i�fflatio�f �bressure label, you should determi�fe
the �bro�ber tire i�fflatio�f �bressure for those tires.)
As a�f added safety feature, your vehicle has
bee�f equi�b�bed with a Tire Pressure Mo�fitori�fg
System (TPMS) that illumi�fates a low tire
�bressure telltale whe�f o�fe or more of your tires
is sig�fifica�ftly u�fder-i�fflated. Accordi�fgly, whe�f the low tire �bressure telltale illumi�fates, you
should sto�b a�fd check your tires as soo�f as
�bossible, a�fd i�fflate them to the �bro�ber �bres-
sure. Drivi�fg o�f a sig�fifica�ftly u�fder-i�fflated tire
causes the tire to overheat a�fd ca�f lead to tire
failure. U�fder-i�fflatio�f also reduces fuel effi-
cie�fcy a�fd tire tread life, a�fd may affect the
vehicle’s ha�fdli�fg a�fd sto�b�bi�fg ability.
If the vehicle is bei�fg drive�f with o�fe or more flat
tires, the low tire �bressure war�fi�fg light will
illumi�fate co�fti�fuously a�fd a chime will sou�fd
for 10 seco�fds. The chime will o�fly sou�fd at the
first i�fdicatio�f of a flat tire, a�fd the war�fi�fg light
will illumi�fate co�fti�fuously. Whe�f the flat tire
war�fi�fg is activated, have the system reset a�fd
the tire checked a�fd re�blaced if �fecessary by a
GT-R certified NISSAN dealer. Eve�f if the tire is
i�fflated to the s�becified COLD tire �bressure, the
war�fi�fg light will co�fti�fue to illumi�fate u�ftil the
system is reset by a GT-R certified NISSAN
dealer. Your vehicle ca�f be drive�f for a limited
time o�f a flat tire. (

Please �fote that the TPMS is �fot a substitute for
�bro�ber tire mai�fte�fa�fce, a�fd it is the driver’s
res�bo�fsibility to mai�ftai�f correct tire �bressure,
eve�f if u�fder-i�fflatio�f has �fot reached the level

DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of
alcohol or drugs. Alcohol in the blood-
stream reduces coordination, delays
reaction time and impairs judgement.
Driving after drinking alcohol increases
the likelihood of being involved in an
accident injuring yourself and others.
Additionally, if you are injured in an
accident, alcohol can increase the se-
verity of the injury.
NISSAN is committed to safe driving. \fowever,
yo\b m\bst choose not to drive \bnder the infl\bence
of alcohol. Every year tho\bsands of people are
inj\bred or killed in alcohol-related accidents.
Altho\bgh the local laws vary on what is
considered to be legally intoxicated, the fact is
that alcohol affects all people differently and
most people \bnderestimate the effects of
alcohol.
Remember, drinking and driving don’t mix! And
that is tr\be for dr\bgs, too (over-the-co\bnter,
prescription, and illegal dr\bgs) . Don’t drive if
yo\br ability to operate yo\br vehicle is impaired by alcohol, dr\bgs, or some other physical condition.
ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS
WARNING
.
Do not drive beyond the perfor-
mance capability of the tires, even
with AWD engaged. Accelerating
quickly, sharp steering maneuvers
or sudden braking may cause loss
of control.
. Always use the specified tires on all
four wheels. Install tire chains on
the rear wheels when driving on
slippery roads and drive carefully.
. This vehicle is not designed for
offroad (rough road) use. Do not
drive on sandy or muddy roads that
tires may get stuck in.
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any
&A
F&Mor&Rposition
with the engine running. Doing so
may result in drivetrain damage or
unexpected vehicle movement
which could result in serious vehicle
damage or personal injury. .
Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer, (such as the dynam-
ometers used by some states for
emissions testing) , or similar equip-
ment even if the other two wheels
are raised off the ground. Make sure
you inform test facility personnel
that your vehicle is equipped with
AWD before it is placed on a
dynamometer. Using the wrong test
equipment may result in drivetrain
damage or unexpected vehicle
movement which could result in
serious vehicle damage or personal
injury.
. When a wheel is off the ground due
to an unlevel surface, do not spin
the wheel excessively.

“Warnin�f/indicator li�fhts
and audible reminders” pa�fe 2-25) NOTE:
.
This vehicle includes spark plugs that
are designed for maximum perfor-
mance. If the start time becomes long-
er, the plugs may be fouled, making the
engine difficult to start. If this occurs,
start the engine using the procedure
described in this section.
. A click sound may be heard when the
brake pedal is depressed and released.
This is normal.
. A low rattling operating sound may
occur when the engine is started or
stopped. This is because of the trans-
mission gear design, light flywheel and
dry sump lubrication system used in
this transmission. This does not indi-
cate that there is a malfunction. This
sound is likely to occur in particular if
the engine is stopped when the tem-
perature of the transmission oil is high.

5. To stop the engine, move the shift leve\f to the
&Pposition, and push the ignition switch
to the OFF position. NOTE:
.
Care should be taken to avoid situa-
tions that can lead to potential battery
discharge and potential no-start condi-
tions such as:
a. Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
b. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
. If the engine is difficult to start, de-
press the accelerator pedal all the way
to the floor and hold it. Push the
ignition switch with the brake pedal
depressed to start cranking the engine.
After 5 or 6 seconds, stop cranking by
pushing the ignition switch to the OFF
position, and then release the accel-
erator pedal. Then perform steps 1 to 5
to start the engine. If the engine starts,
but fails to run, repeat this procedure.
. Starting and stopping the engine over a
short period of time may make the
vehicle more difficult to start. If this
occurs, wait for more than 3 minutes, and then push the ignition switch again
to start the engine.
. To maintain high performance over a
long period of time, the engine speed is
limited to 5,000 rpm when the engine is
revved with the shift lever in the
&Nor
&Pposition, and to 4,000 rpm when the
engine oil or coolant temperature is
low or higher than normal.
. If the ignition switch is pushed before
the shift lever is moved to the
&P
position, the ignition switch will not
change to the OFF position. If this
occurs, the SHIFT
&Pwarning display
appears on the vehicle information
display. When stopping the engine, be
sure to move the shift lever to the
&P
position and then push the ignition
switch. Failure to do so may result in
discharge of the battery. (
“Shift
“P” warning” page 2-43)
. If the shift lever was in the
&A
F&Mor&R
position when the engine was stopped,
then be sure to move the shift lever to
the
&Pposition before starting the
engine the next time. If the engine is
started with the shift lever in the
&N
position, then it may not be possible to

drive the vehicle even when the shift
lever is moved to the&A
F&Mor&R
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
Starting and driving5-15

medical devices or other electronic
products that are susceptible to
magnetic force close to the shift
lever.
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
. If the shift lever is moved from
&Rto
&A
F&Mposition, or&A
F&Mto&R
position before the vehicle stops,
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 automati-
cally controls the clutch and shifting
operation of the manual transmis-
sion, whenever the shift lever is in a
position other then
&Por&N, 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 circum-
stances the vehicle may not start
moving on its own, however this
does not indicate that there is a
malfunction.
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 GT-R dual clutch transmission 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 transmission temperature is low
(approximately 104 8F (408C) , do not
accelerate rapidly or run the engine faster than 4,000 rpm.

Operating the shift lever
After starting the engine, fully depress the brake
pedal and �fove the shift lever fro�f the&P
