NOTICE
Never place anything except the Intelli-
gent Key in the Intelligent Key port.
Doing so may cause damage to the
equipment.
NOTE:
.
Make sure the Intelligent Key is in the
correct direction when inserting it into
the Intelligent Key port. The engine
may not start if it is in the incorrect
direction.
. Remove the Intelligent Key from the
Intelligent Key port after the ignition
switch is pushed to the OFF position.
. The Intelligent Key port does not
charge the Intelligent Key battery. If
you see the low battery indicator in the
vehicle information display, replace the
battery as soon as possible.

(“Intelligent Key battery replace-
ment” page 8-27) .
Make sure the area around the vehicle is
clear.
. Check fluid levels such as en�fine oil, cool-
ant, brake fluid and �bindo�b �basher fluid as
frequently as possible, or at least �bhenever
you refuel.
. Check that all �bindo�bs and li�fhts are clean.
. Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
. Lock all doors.
. Position seat.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen�fers to
do like�bise.
. Check the operation of �barnin�f li�fhts �bhen
the i�fnition s�bitch is pushed to the ON
position. (
“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.

1. Check the positions of the accele\fato\f pedal
*1and b\fake pedal*2. Ad\bust the stee\fing
wheel and seat positions so that the co\f\fect
d\fiving postu\fe is achieved. (
“F\font

2. Check that the pa\fking b\fake is engaged.
3. Check that the shift leve\f is in the
&Po\f&N
position. (&Pis \fecommended.)
4. Fi\fmly dep\fess the b\fake pedal. Without dep\fessing the accele\fato\f pedal, push the
ignition switch once to sta\ft the engine.
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
DRIVING THE VEHICLE

5-16Starting and driving
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
position to the&R,&N, or&A
