2015 NISSAN GT-R engine

WARNING
.When the shift lever is in the&A
position, the adaptive shift control
system will stay in a low gear in
order to maintain the effectiveness
of the engine brake. However if the
vehicle is traveling too fast depend-
ing on the degree of the slope, you
should shift to the
&Mposition and
use the paddle shifter to shift down.
If you continue to use only the foot
brake, a high load will be applied to
the brake, which may overheat,
reducing its effectiveness. Be sure
to use the engine brake together
with the foot brake. (
“Adaptive
shift control” page 5-19)
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
NOTICE
When driving in the&Aposition, gear-
shifting will be performed automatically
with the adaptive shift control system
(
“Adaptive shift control” page 5- 19) even on road conditions with con-
tinuous and sudden hills or curves.
However, when the transmission oil
temperature is low immediately after
starting the vehicle or high when enga-
ging in high performance driving, there
may be some cases where the system
cannot control shifting. When this oc-
curs, switch to the
&Mposition and
select a lower gear, depending on the
gradient of the hill.
When stopping the vehicle
Leave the shift lever in the&A
F&Mor&Rposition
and firmly depress the foot brake pedal\f
If the vehicle will be stopped for a lon\b period of
time, apply the parkin\b brake and move the shift
lever to the
&Por&Nposition as necessary\f
WARNING
. Do not race the engine while the
vehicle is stopped. Doing so may
accelerate the vehicle suddenly and
cause an accident when shifting to a
driving gear.
. While the engine is running, the
propeller shaft that transmits torque from the engine to the transmission
is turning at all times. Crawling or
reaching under the vehicle while the
engine is running may result in
serious injury.
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.
When parking the vehicle
WARNING
Follow the instructions below when
parking the vehicle to help prevent the
brake rotor and brake pads from rust-
ing together. Failure to follow the
instructions could cause the rotor and
pads to rust together. If the rotor and
pads rust together, there may be a
popping noise and some vibration
Starting and driving5-23

5-24Starting and driving
when the vehicle is driven, a wheel may
not roll correctly, or the brake pads
could be damaged. If the pads are
damaged, this may reduce the effec-
tiveness of the brake system which
could cause a collision, serious perso-
nal injury or death.
The GT-R uses brake pad mater�fals that have
h�fgh metall�f�b �bontent. The brake pad mater�fal
helps ma�fnta�fn brak�fng performan�be �fn a w�fde
range of weather and dr�fv�fng �bond�ft�fons.
For the f�frst 3,000 m�fles (5,000 km) of the
veh�f�ble’s serv�f�be l�ffe, and for the f�frst 3,000 m�fles
(5,000km) after a brake repla�bement, the brake
pad to brake rotor �blearan�be �fs very small. When
park�fng, apply the park�fng brake and move the
sh�fft lever to the
&Ppos�ft�fon. Idle the eng�fne for
more than 20 se�bonds w�fthout depress�fng the
brake pedal. Th�fs allows the brake pads to move
away from the rotor so the pad does not �bonta�bt
the rotor.
Add�ft�fonally, the brakes must be dry before
park�fng the veh�f�ble after dr�fv�fng on wet roads or
after wash�fng the veh�f�ble. If the roads are wet,
l�fghtly apply the brakes for a short d�fstan�be
before park�fng the veh�f�ble to dry the brakes.
After wash�fng the veh�f�ble, dry the brakes by
dr�fv�fng on a dry road for a few m�fles and apply the brakes normally based on traff�f�b and road
�bond�ft�fons.
The metall�f�b brake pads and brake d�fs�b rotor
may rust together when the brakes are not
appl�fed:
.
If the veh�f�ble �fs not �fdled for 20 se�bonds
w�fthout the brakes appl�fed, or �ff the brakes
are appl�fed when the veh�f�ble �fs shut off, the
rotor and pads �ban rust together, even when
the brake pads are dry.
. If the brakes are wet when the veh�f�ble �fs
parked and the park�fng brake �fs appl�fed for a
long t�fme.
Conta�bt a GT-R �bert�ff�fed NISSAN dealer �ff the
brake pads and brake rotor have rusted
together.
1. Br�fng the veh�f�ble to a �bomplete stop.
2. W�fth the foot brake pedal depressed, apply the park�fng brake.
3. Move the sh�fft lever to the
&Ppos�ft�fon.
4. Che�bk the sh�fft lever pos�ft�fon �fnd�f�bator on the �fnstrument panel to �bonf�frm that the
&P
pos�ft�fon �fs sele�bted.
5. Push the �fgn�ft�fon sw�ft�bh to stop the eng�fne.
WARNING
Before exiting the vehicle, be sure to
move the shift lever to the&Pposition
and stop the engine. If the engine is
running and the shift lever is not in the
&Pposition, the vehicle may start mov-
ing due to partial engagement of the
clutch or to the effects of gravity on a
slope, or the vehicle may suddenly
accelerate due to accidental operation
of the accelerator pedal, possibly caus-
ing an accident.

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.

conditions, and oil consumption by
itself does not necessarily indicate
any malfunction. If your rate of oil
consumption increases suddenly or
without explanation, NISSAN recom-
mends that you have your vehicle
inspected by a GT-R certified NISSAN
dealer.This function enables the d\five\f to sta\ft accel-
e\fation f\fom a stop b\b selecting R mode with the
VDC and t\fansmission setup switch. The engine
output will be maintained at app\foximatel\b 4,000
\fpm. When using the R mode o\f the R mode

tion and follow the safet\b inst\fuctions in Section
1 of this manual.
WARNING
.
Failure to follow the warnings and
instruction for the use of this fea-
ture may cause a loss of vehicle
control or a collision which may lead
to serious personal injury or death:
. Make sure to drive carefully within
legal limits.
. Only use this function when you can
guarantee that it is safe to do so,
based on the surrounding traffic
conditions.
. Do not use this function on slippery
or wet roads. This may cause loss of
vehicle control and could result in
an accident.
. The R mode start function has been
developed not only for controlling the engine, transmission and VDC
system, but also the settings of the
suspension and tires. Therefore, any
modification of the vehicle may
disrupt the vehicle’s balance. This
will not only reduce the optimum
performance of the vehicle but may
also cause damage to powertrain
components, including the trans-
mission.
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: 1408F - 2128F
(608C - 1008C)
— Transmission oil: 1408F - 2668F (608C - 1308C)
. 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 dis-
R MODE START FUNCTION

abled, the warning light illuminates.
When the warning light illuminates,
perform cool down driving.
(
“Cool down” page GTR-13)
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 temperature. (This vehicle
was set up according to the road
surface conditions of the straight
sections of the Sendai Highland
Raceway course in Japan at 598F
(158C) .)
. 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 more quickly.
