2014 NISSAN GT-R stop start

5-44Starting and driving
The rear final drive of this vehicle is equipped
with a 1.5-way 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.
LIMITED SLIP DIFFERENTIAL (LSD)

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 parking brake.
2. Move the shift lever to the
&Pposition.
3. To help prevent the vehicle from rolling into the street when parked on a sloping drive
way, it is a good practice to turn the wheels
as illustrated.
.HEADED DOWNHILL WITH CURB:*1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
.HEADED UPHILL WITH CURB:*2
Turn the wheels away from the curb and
move the vehicle back until the curb side

Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Push the ignition switch to the LOCK position.
The GT-R uses brake pad materials that have
high metallic content. The brake pad material
helps maintain braking performance in a wide
range of weather and driving conditions.
For the first 3,000 - 6,000 miles (5,000 -
10,000 km) of the vehicle’s service life, and for
the first 3,000 - 6,000 miles (5,000 - 10,000
km) after a brake replacement, the brake pad to
brake rotor clearance is very small. When
parking, apply the parking brake and move the
shift lever to the
&Pposition. Idle the engine for
more than 20 seconds without depressing the
brake pedal. This allows the brake pads to move
away from the rotor so the pad does not contact
the rotor.
Additionally, the brakes must be dry before
parking the vehicle after driving on wet roads or
after washing the vehicle. If the roads are wet,
lightly apply the brakes for a short distance
before parking the vehicle to dry the brakes.
After washing the vehicle, dry the brakes by driving on a dry road for a few miles and apply
the brakes normally based on traffic and road
conditions.
The metallic brake pads and brake disc rotor
may rust together when the brakes are not
applied:
.
If the vehicle is not idled for 20 seconds
without the brakes applied, or if the brakes
are applied when the vehicle is shut off, the
rotor and pads can rust together, even when
the brake pads are dry.
. If the brakes are wet when the vehicle is
parked and the parking brake is applied for a
long time.
Contact a GT-R certified NISSAN dealer if the
brake pads and brake rotor have rusted
together.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
POWER STEERING

BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and pads faster
and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
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
drums/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual and can be performed by a
GT-R certified NISSAN dealer.

BRAKE SYSTEM

5-48Starting and driving
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 System (ABS) controls the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
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
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forwardor reverse. When the self-test occurs, you may
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This does not indicate that there is
a malfunction. If the computer senses a mal-
function, it switches the ABS off and illuminates
the ABS warning light on the instrument panel.
The brake system then operates normally, but
without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while 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 km/h). The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
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
specially formulated rubber to maximize the
vehicle’s performance capabilities. Performance
of summer tires is substantially reduced when
temperatures are less than 328F(08C) so you
must drive carefully. NISSAN recommends the
use of winter or all-season tires on all four
wheels if you plan to operate your vehicle in
snowy or icy conditions when temperatures are
less than 328F(0 8C) .
WARNING
Never use summer tires when the
temperature is below −48F(−208C) 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 may be used. (
“Tire chains”
page 8-40)
If you install tires, they 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 vehicle during winter:
. A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
. A sturdy, flat board to be placed under the
jack to give it firm support.
. A shovel to dig the vehicle out of snowdrifts.
. Extra window washer fluid to refill the
reservoir 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 overheating (indicated by an
extremely high temperature gauge reading) , or if
you feel a lack of engine power, detect unusual
noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply the parking 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
maximum hot and fan control to high speed. 3. If engine overheating is caused by climbing
a long hill on a hot day, run the engine at a
fast idle (approximately 1,500 rpm) until the
temperature gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radiator
before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no steam
or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the drive belts are missing or loose, or the
cooling fan does not run, stop the engine.
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 gauge goes down to the midpoint, stop the engine and
wait until the gauge goes down further to
“C” (cold).
8. After the engine cools down, check the coolant level in the reservoir tank. Add
coolant to the reservoir, if necessary, after
opening the coolant reservoir cap with a
heavy cloth covering it. (
“Engine cool-
ing system” page 8-10)
9. Have your vehicle repaired at the nearest GT-R certified NISSAN dealer.
