the wheels. The tire may slip on the wheel if
the vehicle is driven in these conditions
before 48 hours have passed. If the tire slips
on the wheel, the wheel/tire assembly will be
out of balance and will require rebalancing.
Brakes
The information and specifications in this
section apply only when engaging in
performance driving.
.Check for the heat deterioration of the
brakes and parts around the brakes.
. It is recommended that you remove air from
the brake system after any of the following:
— When engaging in high performance
driving for the first time after purchasing
a new vehicle.
— After replacing the brake fluid.
— When engaging in high performance driving for a sustained period of time. It
is recommended that bleeding the brake
be performed when the brake calipers
are hot (about 2128F (1008C)) .
Brake pad:
NISSAN recommends adding an additional
cross spring to the front calipers before enga-
ging in performance driving. The additional
spring reduces brake pad movement resulting from cornering forces and will reduce the stroke
of the brake pedal. Contact a GT-R certified
NISSAN dealer to purchase the spring and
arrange installation. If a cross spring is added, a
clattering or squeaking sound may be heard on
rare occasions.
Brake pad break-in procedure:
NISSAN recommends that a special brake pad
break-in procedure be performed before enga-
ging in performance driving. Contact a GT-R
certified NISSAN dealer for details.
INSPECTION AND ADJUSTMENTS
AFTER DRIVING
The information and specifications in this
section apply only when engaging in
performance driving.
NOTICE
At the completion of performance driv-
ing, all fluid and other adjustments
should be returned to the normal fluid
specifications as shown in the “Main-
tenance and do-it-yourself” section of
this manual.
Fluids
The information and specifications in this
section apply only when engaging in
performance driving.
.
Check the engine, transmission, differential
and under the vehicle for oil and coolant
leaks.
. Check the fluid levels and adjust as neces-
sary using the specified fluid as described
under the conditions listed in this section.
(
“Recommended fluids and mainte-
nance interval” page GTR-20) If you do not
drive under the conditions listed, refer to the
2014 NISSAN Service and Maintenance
Guide.
. When changing fluids, be sure to use the
specified fluids as described in this Owner’s
manual. (
“Capacities and recom-
mended fuel/lubricants” page 9-2)
GT-R OverviewGTR-19

Suspension and wheel alignment
.Check the steering and suspension system
and other links for loose and/or damaged
parts.
. Measure and adjust the wheel alignment.
Contact a GT-R certified NISSAN dealer to
adjust the wheel alignment to the recom-
mended setting for normal driving.
Wheels and tires
.Check tire wear and cracking.
. Inspect the tire side wall for damage.
. Check the tire pressure and adjust the
pressure as necessary when the tires are
cold. (
“Wheels and tires” page GTR-
17) If you do not drive under the conditions
listed in this section, see (
“Wheels and
tires” page 8-32)
. Check that the wheel nuts are not stripped.
Check if there is no deformation on the
contact surface of the wheel nuts.
. Make sure the wheel nuts are tight.
(
“Wheels and tires” page 8-32)
. Make sure the drive shaft nuts are tight.
. Check wheel hub run out and that the wheel
rotates smoothly without any friction. Check
these with the tires removed whenever an inspection is performed with the vehicle
jacked up.
. Make sure the tire has not slipped on the
wheel causing the assembly to be out of
balance. The reference marks on the tire and
wheel should be aligned. If the reference
marks are not aligned, the tire has slipped on
the wheel. Have the wheels/tires reba-
lanced. Make sure the old reference marks
are erased and new reference marks are
applied to the wheel and tire. When instal-
ling new tires on the wheels, make sure new
reference marks are applied to the wheels
and tires. (
“Wheels and tires” page
GTR-17)
. Make sure that the TPMS sensor installation
nuts and the sensor valve are tight and there
is no nitrogen leak.
Brakes
.Check for the heat deterioration of the
brakes and parts around the brakes.
. Check the condition of the brake pads and
disc rotors and replace them as necessary.
Engine and powertrain
.Check the engine, transmission, differential
and under the vehicle for oil and coolant leaks.
. Inspect the area surrounding the catalytic
converter for heat deterioration.
. Inspect and confirm the clearance between
the exhaust finisher and rear bumper is more
than 0.24 in (6 mm) (up/down) and more
than 0.20 in (5 mm) (left/right) .
. The clutch clearance and shift fork position
may need to be adjusted.
. Inspect the dust boot of the drive shaft
universal joint for cracks or damage.
. Check that there is no abnormal noise,
vibrations or warning lights illuminated when
making tight turns at slow speed (for tight
corner braking phenomenon) .
GT-R OverviewGTR-23

GTR-26GT-R Overview
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
&P
position. 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 secondswithout 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.
— The hill start assist system can apply the brakes even if the brake pedal is not
depressed. The brake pads and rotors
can rust together if the parking proce-
dure previously described is not fol-
lowed.
Contact a GT-R certified NISSAN dealer if
the brake pads and brake rotor have rusted
together.
NOTICE
To help reduce the possibility of the
rotors and brake pads rusting:
Have the brake pads and/or rotors
quenched when the brake pads are
replaced. For detailed information
about quenching, contact a GT-R certi-
fied NISSAN dealer.
After quenching the brake pads and/or
rotors, apply a brake of 0.5G to stop the
vehicle 6-7 times at least once a week
in a safe location. G-force can be
checked on the multi function display. Refer to the separate Multi Function
Display Owner’s Manual.
. To maintain steady braking performance in
both extremely high and low temperatures,
the gap between the brake pad and caliper
is larger than normal and large-size brake
pads are used. When driving over a bump, a
light rattling sound may be heard from the
brake pad. This does not indicate that there
is a malfunction.
. When the brake disc rotor undergoes
thermal expansion, a ticking noise may be
heard from the engaging portion of the
wheel and the brake disc rotor. This does
not indicate that there is a malfunction. The
noise will reduce when the temperature
decreases.
. In addition to noise resulting from uneven
tire wear discussed in the previous section,
the GT-R tires are more rigid than a typical
passenger car tire and are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. These
characteristics cause the GT-R tires to have
more road noise than a typical passenger
car tire. This road noise is normal.

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.
