in this section for 48 hours after tires
are installed on 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.
BrakesThe 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 perfor-
mance driving for the first time
after purchasing a new vehicle.
— After replacing the brake fluid.
— When engaging in high perfor- mance driving for a sustained per-
iod of time. It is recommended that
bleeding the brake be performed
when the brake calipers are hot
(about 212°F (100°C)). Brake pad break-in procedure:
NISSAN recommends that a special brake
pad break-in procedure be performed
before engaging in performance driving.
It is recommended you contact a GT-R
certified NISSAN dealer for details.

AFTER DRIVINGThe information and specifications in
this section apply only when engaging
in performance driving.
NOTICE
At the completion of performance
driving, all fluid and other adjust-
ments should be returned to the
normal fluid specifications as shown
in the “8. Do-it-yourself” section of
this manual.FluidsThe information and specifications in
this section apply only when engaging
in performance driving.
.
Check the engine, transmission, differ-
ential and under the vehicle for oil and
coolant leaks. .
Check the fluid levels and adjust as
necessary using the specified fluid as
described under the conditions listed
in this section. (
“Recommended
fluids and maintenance interval” page
GTR-20) If you do not drive under the
conditions listed, refer to the “9. Main-
tenance and schedules” section of this
manual.

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 hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the
brake pedal and apply the accelerator
when the vehicle is stopped on a hill.
Hill start assist will operate automatically
under the following conditions:
. The shift lever is moved to a forward
or reverse position.
. The vehicle is stopped completely on a
hill by applying the brake.
The maximum holding time is 2 seconds.
After 2 seconds the vehicle will begin to
roll back and hill start assist will stop operating completely.
Hill start assist will not operate when the
shift lever is moved to the
or
position
or on a flat and level road.
NOTE:
This system does not function when the
Vehicle Dynamic Control VDC) system
warning appears on the vehicle infor-
mation display located in the tach-
ometer. (

HILL START ASSIST SYSTEM

For models without NCCB (NISSAN Car-
bon Ceramic Brake) package:
NISSAN generally recommends to replace
all four sets of brake pads and disc rotors
at the same time to maintain maximum
brake performance.However, replacing only the brake pads
may be allowed in some cases (four
wheels or only front wheels depending
on the conditions). A GT-R certified tech-
nician must inspect the vehicle and
determine that only the brake pads need
to be replaced. In this case, replacing all
brake pads and disc rotors as a set is not
necessary.
Note that the replacement of brake pads
and the disc rotors as a set on all four
wheels should be performed when a GT-R
certified technician determines that this
is the correct repair.
If the inside of the disc rotors are cold
during the winter and the surface be-
comes hot due to a heavy force being
applied repeatedly to the brakes, cracks
may occur near the coolant hole on the
surface of the disc rotor. Cracks may also
occur due to a heavy force being repeat-
edly applied to the brakes during high
performance driving. In these cases it
may be necessary to replace the disc
rotors or brake pads depending on the
condition of the crack. We recommend
contacting a GT-R certified NISSAN dealer
for replacement.

BRAKE SYSTEM INFORMATION
Cracks on brake padThe friction material of the GT-R disc
brake pad is bonded to the pad backing
plate more strongly than conventional
brake pads to withstand the high brake
temperatures. The friction material and
backing plate expand due to heat at
different rates. Some cracks may be on
the surface of the friction material due to
the differences in expansion rates and the
strong bond between the friction material
and backing plate. The cracks do not
indicate the brake pads need to be
replaced. However, depending on the
condition of the cracks, the pads may
need to be replaced. It is recommended
you contact a GT-R certified NISSAN deal-
er.
. This is due to the temperature
differential that occurs because the sur-
faces of the disc rotors become hot while
the inside of the rotor is still cold. How-
ever, this poses no problem in terms of
brake performance, and does not indicate
a malfunction. The brakes do not need to

position and the
ignition switch is in the ON position.
. The shift lever is in the
position and
5 minutes have passed while the
ignition switch is in the ON position.
Be sure to move the shift lever out of the
position after driving in reverse.Brake pad wear warning (models
without NCCB (NISSAN Carbon
Ceramic Brake) package)The disc brake pads have audible wear
warnings. 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.

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.
CAUTION
. Because the vehicle includes a
dual clutch transmission that
automatically controls the clutch
and shifting operation of the
manual transmission, whenever
the shift lever is in a position
other than

, the vehicle will
begin to move slowly, in the same
way as when the clutch in a
manual transmission vehicle is
partially engaged. Keep the brake
pedal firmly depressed when the vehicle is stopped. In some cir-
cumstances the vehicle may not
start moving on its own, however
this does not indicate that there
is a malfunction.
NOTICE
.
To avoid possible damage to your
vehicle; when stopping the vehi-
cle on an uphill grade, do not hold
the vehicle in place by depressing
the accelerator pedal. Doing so
may cause the clutch to overheat
and result in transmission da-
mage. Use the brakes to prevent
the vehicle from moving.
. The GT-R dual clutch transmis-
sion 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 trans-
mission temperature is low (ap-
proximately 104°F (40°C), do not
accelerate rapidly or run the en-
gine faster than 4,000 rpm.

NOTICE
.When the temperature of the
engine coolant and transmission
oil is high or low, the function
cannot be used. The temperature
range in which the R mode start
function can be used:
— Engine coolant: 140°F - 212°F
(60°C - 100°C)
— Transmission oil: 140°F - 266°F (60°C - 130°C)
. If the R mode start function is
used 4 times consecutively, the
function may be disabled and
cannot be turned on to protect
the vehicle system. While the function is disabled, the warning
light illuminates. When the warn-
ing light illuminates, perform cool
down driving. (
“Cool down”
page GTR-14) 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 tempera-
ture. (This vehicle was set up
according to the road surface
conditions of the straight sec-
tions of the Sendai Highland Ra-
ceway course in Japan at 59°F
(15°C).)
. 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
