.T�fis mode is for use in a broad range of driving conditions�b for routine driving during
fair to rainy weat�fer�b as well as for driving on road surfaces t�fat are slippery due to
snow or ice.
Make sure to use t�fis mode for everyday driving.
.Temporary mode t�fat can be used to free if it is stuck in snow or mud
(Wit�f t�fe transmission switc�f in SAVE mode�b freeing t�fe ve�ficle become easier.)
NOTE:
Always make sure the VDC is ON before driving the vehicle by checking that the VDC OFF
indicator lights on the meter and the VDC set-up switch are not illuminated. The GT-R is a
high performance vehicle and the VDC must be on/activated to provide proper powertrain
operation and intended drivability.
WARNING
. The VDC OFF mode should ONLY be
used briefly to help free the vehicle
if stuck in snow or mud by tempora-
rily stopping operation of the VDC
to maintain wheel torque.
. Driving the GT-R with the VDC off
may lead to handling issues related
to steering maneuvers, acceleration,
or deceleration. Moreover, driving
with the VDC off can result in an
inoperative vehicle by causing ser-
ious damage to the powertrain,
including damage to the Transaxle
Assembly including Transfer, Clutch,
Gears, Transaxle case and all of its
components and other drivetrain
component(s) by overheating or ex-
cessive force.
. Damage to the powertrain or any
drivetrain component(s) that occurs
when there is a record in the Vehicle
Status Data Recorder (VSDR) that
the vehicle was driven with VDC off
during the period when the damage
was incurred is excluded from war-
ranty coverage.

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.
HOW TO USE R MODE START
