2015 NISSAN GT-R steering

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.

POWER STEERING

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

5-50Starting and driving
The Vehicle Dynamic Control �fVDC) system
uses �barious sensors to monitor dri�ber inputs
and �behicle motion. Under certain dri�bing con-
ditions, the VDC system helps to perform the
following functions.
.Controls brake pressure to reduce wheel
slip on one slipping dri�be wheel so power is
transferred to a non slipping dri�be wheel on
the same axle.
. Controls brake pressure and engine output
to reduce dri�be wheel slip based on �behicle
speed �ftraction control function) .
. Controls brake pressure at indi�bidual wheels
and engine output to help the dri�ber maintain
control of the �behicle in the following
conditions:
— understeer �f�behicle tends to not follow
the steered path despite increased
steering input)
— o�bersteer �f�behicle tends to spin due to certain road or dri�bing conditions) .
The VDC system can help the dri�ber to maintain
control of the �behicle, but it cannot pre�bent loss
of �behicle control in all dri�bing situations.
When the VDC system operates, the VDC
warning light
in the instrument panel flashes
so note the following: .
The road may be slippery or the system may
determine some action is required to help
keep the �behicle on the steered path.
. You may feel a pulsation in the brake pedal
and hear a noise or �bibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
. Adjust your speed and dri�bing to the road
conditions.
. The VDC mode can be changed using the
VDC setup switch. �f

sion and suspension setup switches” page
5-25)
�f
“Vehicle Dynamic Control �fVDC) warning
light” page 2-31,“Vehicle Dynamic Con-
trol �fVDC) off indicator light” page 2-32)
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
The VDC setup switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is off.
When the VDC setup switch is used to turn off
the system, the VDC system still operates to
pre�bent one dri�be wheel from slipping by
transferring power to a non slipping dri�be wheel.
The VDC warning light
flashes if this
occurs. All other VDC functions are off and the VDC warning light
will not flash. The VDC
system is automatically reset to on when the
ignition switch is placed in the off position then
back to the on position.

“Vehicle Dynamic Control �fVDC) warning
light” page 2-31,“Vehicle Dynamic Con-
trol �fVDC) off indicator light” page 2-32)
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and mo�be the �behicle forward or in
re�berse at a slow speed. When the self-test
occurs, you may hear a “clunk” noise and/or feel
a pulsation in the brake pedal. This is normal and
is not an indication of a malfunction.
WARNING
. The VDC system is designed to help
the driver maintain stability but
does not prevent accidents due to
abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful
when driving and cornering on slip-
pery surfaces and always drive care-
fully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM

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.

COLD WEATHER DRIVING

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.
Starting and driving5-53

To shut off the engine in an emergency situation
while dri�fing, perform the following procedure:
.�bapidly push the push-button ignition switch
3 consecuti�fe times in less than 1.5
seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This �fehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire
pressure of all tires. When the low tire pressure
warning light is lit, one or more of your tires is
significantly under-inflated. If the �fehicle is being
dri�fen with low tire pressure, the TPMS will
acti�fate and warn you of it by the low tire
pressure warning light (in the instrument panel)
or the warning message (on the display) . This
system will acti�fate only when the �fehicle is
dri�fen at speeds abo�fe 16 MPH (25 km/h) .
(
“Low tire pressure warning light” page 2-
27) (“Tire Pressure Monitoring System
(TPMS)” page 5-4)
WARNING
. If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possi-
ble. Driving with under-inflated tires
may permanently damage the tires
and increase the likelihood of tire
failure. Serious vehicle damage could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pres-
sure for all four tires. Adjust the tire
pressure to the recommended COLD
tire pressure shown on the Tire and
Loading Information label to turn
the low tire pressure warning light
off. If the light still illuminates while
driving after adjusting the tire pres-
sure, a tire may be flat.
. When a wheel is replaced, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light
will remain on after 1 minute. Con-
tact a GT-R certified NISSAN dealer
as soon as possible for tire replace-
ment and/or system resetting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of
the tire pressure sensors.
