2015 NISSAN GT-R stop start

The rear final drive of this vehicle is equipped
with a \f.5-wa\b mechanical Limited Slip Differ-
ential (LSD) .
WARNING
Sudden operation of the accelerator
pedal can result in fishtailing or side-
slip, possibly causing an accident. Use
particular caution when driving in rainy
weather or on slippery roads.
NOTICE
Use the designated differential gear oil.
If any oil other than the designated oil
is used, the LSD may not operate
correctly, and noise and vibration may
occur, possibly resulting in a malfunc-
tion.
NOTE:
. If the vehicle accelerates from a stop
with the steering wheel turned in cold
temperatures, the inner wheel tire may
slip and some noise or vibration may
be heard. This phenomenon is unique
to vehicles equipped with the LSD. This does not indicate that there is a mal-
function.
. The LSD controls the speed difference
between the left and right wheels, and
optimally allocates torque to the
wheels.
. The 1.5-way mechanical LSD in the rear
final drive of this vehicle is character-
ized by its asymmetrical LSD effects
when the accelerator pedal is ON and
when it is OFF. This allows the appro-
priate amount of torque for the driving
environment to be transmitted to the
road surface.

WARNING
.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.
. Never leave the engine running
while the vehicle is unattended.
. Do not leave children unattended
inside the vehicle. They could un-
knowingly activate switches or con-
trols. Unattended children could
become involved in serious acci- dents.
. Safe parking procedures require
that both the parking brake be
applied and the transmission placed
into the
&Pposition. Failure to do so
could cause the vehicle to move
unexpectedly or roll away and result
in an accident.
. Make sure the shift lever has been
pushed as far forward as it can go
and cannot be moved without de-
pressing the foot brake pedal. .
Follow the instructions below when
parking the vehicle to help prevent
the brake rotor and brake pads from
rusting 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 when the vehicle is
driven, a wheel may not roll cor-
rectly, or the brake pads could be
damaged. If the pads are damaged,
this may reduce the effectiveness of
the brake system which could cause
a collision, serious personal injury
or death.
1. Firmly apply the parkin�f brake.
2. M�bve the shift lever t�b the&Pp�bsiti�bn.
3. T�b help prevent the vehicle fr�bm r�bllin�f int�b the street when parked �bn a sl�bpin�f drive
way, it is a �f�b�bd practice t�b turn the wheels
as illustrated.

BRAKING PRECAUTIONS
The brake system has two separate hydra�flic
circ�fits�b If one circ�fit malf�fnctions, yo�f will still
have braking at two wheels�b
Yo�f may feel a small click and hear a so�fnd
when the brake pedal is f�flly depressed slowly�b
This is not a malf�fnction and indicates that the
brake assist mechanism is operating properly�b
Vacuum assisted brakes
The brake booster aids braking by �fsing engine
vac�f�fm�b If the engine stops, yo�f can stop the
vehicle by depressing the brake pedal�b However,
greater foot press�fre on the brake pedal will be
req�fired to stop the vehicle and the stopping
distance will be longer�b
Wet brakes
When the vehicle is washed or driven thro�fgh
water, the brakes may get wet�b As a res�flt, yo�fr
braking distance will be longer and the vehicle
may p�fll to one side d�fring braking�b
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-�fp
the brakes�b Do this �fntil the brakes ret�frn to
normal�b Avoid driving the vehicle at high speeds
�fntil the brakes f�fnction correctly�b
Using the brakes
Avoid resting yo�fr foot on the brake pedal while
driving�b This will ca�fse overheating of the
brakes, wearing o�ft the brake and pads faster
and red�fce gas mileage�b
To help red�fce brake wear and to prevent the
brakes from overheating, red�fce speed and
downshift to a lower gear before going down a
slope or long grade�b Overheated brakes may
red�fce braking performance and co�fld res�flt in
loss of vehicle control�b
WARNING
.While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an
accident.
. If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
dr�fms/rotors are replaced, in order to ass�fre the
best braking performance�b
This proced�fre is described in the vehicle
service man�fal and can be performed by a
GT-R certified NISSAN dealer�b
BRAKE SYSTEM

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance
from the vehicle in front of you.
Ultimately, the driver is responsible
for safety.
. Tire type and condition may also
affect braking effectiveness. When
replacing tires, install the specified
size of tires on all four wheels. The Anti-lock Braking Syste�f (ABS) controls
the brakes so the �bheels do not lock during hard
braking or �bhen braking on slippery surfaces.
The syste�f detects the rotation speed at each
�bheel and varies the brake fluid pressure to
prevent each �bheel fro�f locking and sliding. By
preventing each �bheel fro�f locking, the syste�f
helps the driver �faintain steering control and
helps to �fini�fize s�berving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it do�bn.
Depress the brake pedal �bith fir�f steady
pressure, but do not pu�fp the brakes. The
ABS �bill operate to prevent the �bheels fro�f
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pu�fps, hydraulic solenoids and a co�fputer. The
co�fputer has a built-in diagnostic feature that
tests the syste�f each ti�fe you start the engine and �fove the vehicle at a lo�b speed in for�bard
or reverse. When the self-test occurs, you �fay
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This does not indicate that there is
a �falfunction. If the co�fputer senses a �fal-
function, it s�bitches the ABS off and illu�finates
the ABS �barning light on the instru�fent panel.
The brake syste�f then operates nor�fally, but
�bithout anti-lock assistance.
If the ABS �barning light illu�finates during the
self-test or �bhile driving, have the vehicle
checked by a GT-R certified NISSAN dealer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 k�f/h) . The speed varies according to
road conditions.
When the ABS senses that one or �fore �bheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is si�filar to pu�fping the brakes very
quickly. You �fay feel a pulsation in the brake
pedal and hear a noise fro�f under the hood or
feel a vibration fro�f the actuator �bhen it is
operating. This is nor�fal and indicates that the
ABS is operating properly. Ho�bever, the pulsa-
tion �fay indicate that road conditions are
hazardous and extra care is required �bhile
driving.

BRAKE ASSIST

shock absorbers, struts, springs,
stabilizer bars, bushings and
wheels are not NISSAN approved
or are extremely deteriorated, the
VDC system may not operate prop-
erly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are
not standard equipment or are ex-
tremely deteriorated, the VDC warn-
ing light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the VDC warn-
ing light
may illuminate. Do not
drive on these types of roads.
. When driving on an unstable sur-
face such as a turntable, ferry, elevator or ramp, the VDC warning
light
may illuminate. This is not
a malfunction. Restart the engine
after driving onto a stable surface.
. If wheels or tires other than the
those recommended are used, the
VDC system may not operate prop-
erly and the VDC warning light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
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.

TIRE EQUIPMENT
The GT-R summer tires are made from a
speciall�f formulated rubber to maximize the
�behicle’s performance capabilities. Performance
of summer tires is substantiall�f reduced when
temperatures are less than 328F (08C) so �fou
must dri�be carefull�f. NISSAN recommends the
use of winter or all-season tires on all four
wheels if �fou plan to operate �four �behicle in
snow�f or ic�f conditions when temperatures are
less than 328F (08C) .
WARNING
Never use summer tires when the
temperature is belowí48F(í208C) to
prevent permanent tread deformation
which may cause tire damage or tire
failure. This may cause a loss of vehicle
control which can result in serious
personal injury or death.
Tire chains ma�f be used. (
“Tire chains”
page 8-40)
If �fou install tires, the�f must also be the specified
size, brand, construction and tread pattern on all
four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the �behicle during winter:
. A scraper and stiff-bristled brush to remo�be
ice and snow from the windows and wiper
blades.
. A sturd�f, flat board to be placed under the
jack to gi�be it firm support.
. A sho�bel to dig the �behicle out of snowdrifts.
. Extra window washer fluid to refill the
reser�boir tank.
DRIVING ON SNOW OR ICE
WARNING
. Wet ice (328F, 0 8C and freezing rain) ,
very cold snow or ice can be slick
and very hard to drive on. The
vehicle will have much less traction
or “grip” under these conditions. Try
to avoid driving on wet ice until the
road is salted or sanded.
. Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction. .
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances
on slippery roads.
. Watch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a
patch of ice is seen ahead, brake
before reaching it. Try not to brake
while on the ice, and avoid any
sudden steering maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle.
NOTE:
When driving on snow, select the SAVE
mode with the setup switch. By selecting
the SAVE mode, the engine output is
controlled appropriately for snow or slip-
pery road surfaces. This enables the vehi-
cle to start or accelerate smoothly.

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. (
“En�fine cool-
in�f system” pa�fe 8-10)
9. Have your vehicle repaired at the nearest GT-R certified NISSAN dealer.
