2014 NISSAN GT-R brakes

TRANSMISSION OPERATION CHARACTERISTICS
MechanismOperation characteristics
Base Manual transmission
.The GT-R transmission design is different from transmissions used in conventional passenger cars. The GT-R uses a transmission gear
design, light flywheel and a dry sump lubrication system to provide maximum vehicle performance. Because the GT-R Transmission design
is different, noises may be louder. When the transmission temperature is high, rattling, shaking and jarring noises may be heard.
.Clattering noises may be heard while shifting..Appropriate gaps are provided between gears to achieve smooth gear rotation and steady tooth surface lubrication under the high-load
driving condition. However, this causes a rattling noise.
.If the shift lever is moved from&Rto&A↔&Mposition, or&A↔&Mto&Rposition before the vehicle stops, you may not be able to shift gear
or it may take longer to shift gear. Make sure to depress the brake pedal and check that the vehicle has stopped before shifting.
Multiple disc wet clutch
.When stopping the vehicle with the shift lever in the&Ror&A↔&Mposition, be sure to firmly depress the brake pedal. The vehicle may
slowly move if the brake pedal is not depressed.
.Avoid depressing the brake and accelerator pedals at the same time. Depressing the brake and accelerator pedals at the same time could
cause the clutch to overheat and accelerate deterioration.
.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.
Electronic oil pressure
control The following conditions are caused due to changes in fluid viscosity as a result of temperature changes.
.When the transmission oil is extremely cold or extremely hot, the transmission may feel like it is slipping during shifts or there may be hard
shifts. This is normal. Transmission shifting should return to normal when the transmission oil returns to normal operating temperatures.
.When the transmission oil temperature is extremely cold, the time required to run a system check may increase. During the system check,
the shift lever must stay in the&Pposition. Move the shift lever after turning off the system check display. Also, it is normal to hear clicking
noises during the transmission systems check.
Changing modes
.The higher shift speeds in the&Mposition may result in shift shock and jerkiness when starting or shifting..The quickest shifting in the R mode with the transmission in the&Mposition is available when the engine speed is high. However, the
transmission may shift more slowly when the engine speed is low.
Mechanical Limited Slip
Differential (LSD) If the vehicle accelerates from a stop with the steering wheel turned half a turn in cold temperatures, the inner wheel tire may slip and some
noise or vibration may be heard. This phenomenon occurs because the viscosity of the differential oil becomes thicker and the Limited Slip
Differential (LSD) operates with increasing load. When the steering wheel is returned to the straight ahead position or the differential oil warms
up, the noise and vibration decrease.
GT-R OverviewGTR-29

Parking brake reminder chime
A chime will sound if the vehicle speed is above
4 MPH (7 km/h) with the parking brake applied.
Stop the vehicle and release the parking brake.
Reverse reminder chime (if so
equipped)
The chime will sound if the shift lever is in the&R
position while the ignition switch is in the ON
position.
This is not a chime to remind people outside the
vehicle.
Be sure to move the shift lever out of the
&R
position after driving in reverse.
Brake pad wear warning
The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement, it
will make a high pitched scraping sound when
the vehicle is in motion. This scraping sound will
first occur only when the brake pedal is
depressed. After the wear of the brake pad is
increased, the sound will be heard all the time
even if the brake pedal is not depressed. Have
the brakes checked as soon as possible if the
warning sound is heard.
WARNING
When the warning light illuminates or
blinks and a warning is displayed,
promptly take the appropriate action.
Ignoring the warning may result inmalfunctions and accidents.
When the items mentioned below are detected
the master warning light
*1illuminates and the
warning is displayed on the vehicle information
display

OVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times. Obey
all traffic regulations. Avoid excessive speed,
high speed cornering, or sudden steering
maneuvers, because these driving practices
could cause you to lose control of your vehicle.
As with any vehicle, a loss of control could
result in a collision with other vehicles or
objects, or cause the vehicle to rollover,
particularly if the loss of control causes the
vehicle to slide sideways. Be attentive at all
times, and avoid driving when tired. Never drive
when under the influence of alcohol or drugs
(including prescription or over-the-counter
drugs which may cause drowsiness) . Always
wear your seat belt as outlined in this manual,
and also instruct your passengers to do so.
(
“Seat belts” page 1-7)
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash, an
unbelted or improperly belted person is significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If this
occurs, maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel
with both hands and try to hold a straight
course.
4. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the vehicle
speed is reduced. Do not attempt to drive
the vehicle back onto the road surface until
vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return to the
road surface. When all tires are on the road
surface, steer the vehicle to stay in the
appropriate driving lane.
Starting and driving5-7

5-8Starting and driving
.If you decide that it is not safe to return
the vehicle to the road surface based on
vehicle, road or traffic conditions, gradu-
ally slow the vehicle to a stop in a safe
place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged due
to hitting a curb or pothole. Rapid air pressure
loss can also be caused by driving on under-
inflated tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds.
Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspect the tires for wear and damage.
(
“Wheels and tires” page 8-32)
If a tire rapidly loses air pressure or “blows-out”
while driving maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air
pressure. Losing control of the vehicle
may cause a collision and result in
personal injury.
. The vehicle generally moves or pulls
in the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelera-
tor pedal.
. Do not rapidly turn the steering
wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
3. When appropriate, slowly release the accel- erator pedal to gradually slow the vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from traffic if possible.
5. Lightly apply the brake pedal to gradually stop the vehicle. 6. Turn on the hazard warning flashers and
contact a roadside emergency service to
change the tire.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of
alcohol or drugs. Alcohol in the blood-
stream reduces coordination, delays
reaction time and impairs judgement.
Driving after drinking alcohol increases
the likelihood of being involved in an
accident injuring yourself and others.
Additionally, if you are injured in an
accident, alcohol can increase the se-
verity of the injury.
NISSAN is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are
injured or killed in alcohol-related accidents.
Although the local laws vary on what is
considered to be legally intoxicated, the fact is
that alcohol affects all people differently and
most people underestimate the effects of
alcohol.

5-16Starting and driving
partially engaged. Keep the brake
pedal firmly depressed when the
vehicle is stopped. In some circum-
stances the vehicle may not start
moving on its own, however this
does not indicate that there is a
malfunction.
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.
. The GT-R dual clutch transmission is
provided with a dry sump lubrication
system that improves efficiency and
ensures reliability under high g-
force conditions. When oil viscosity
is high at low temperatures, it takes
longer for all components to be
sufficiently lubricated. Thus, when
the transmission temperature is low
(approximately 104 8F (408C) , do not
accelerate rapidly or run the engine faster than 4,000 rpm.
Operating the shift lever
After starting the engine, fully depress the brake
pedal and move the shift lever from the&P
position to the&R,&N,or&A↔&Mposition. Push
the button to shift into the&Por&Rposition. All
other positions can be selected without pushing
the button.

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↔&Mor&Rposition
and firmly depress the foot brake pedal.
If the vehicle will be stopped for a long period of
time, apply the parking brake and move the shift
lever to the
&Por&Nposition as necessary.
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 vibrationwhen 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 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 miles (5,000 km) of the
vehicle’s service life, and for the first 3,000 miles
(5,000km) 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
Starting and driving5-23

5-24Starting and driving
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.
1. Bring the vehicle to a complete stop.
2. With the foot brake pedal depressed, apply the parking brake.
3. Move the shift lever to the
&Pposition.
4. Check the shift lever position indicator on the instrument panel to confirm that the
&P
position is selected.
5. Push the ignition switch to stop the engine.
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.
The control of the dual clutch transmission,
Bilstein DampTronic®electronically controlled
shock absorbers and Vehicle Dynamic Control
(VDC) can be changed to the desired modes by
operating the setup switches. Select the desired
mode best suited to the driving conditions.

5-32Starting and driving
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
