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.
NCCB (NISSAN Carbon Ceramic
Brake) (if so equipped)Replacement of brake pads and
disc rotorsWhen replacing brake pads and brake
disc rotors, NISSAN recommends repla-
cing two sets of them at the same time.

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.

Rattles from brake pads and creaks
during braking
The high performance brake system of
vehicles equipped with the NCCB (NISSAN
Carbon Ceramic Brake) has more clear-
ance between its brake pad and brake
caliper than regular vehicles, and it uses a
large brake pad to ensure stable brakingperformance under a wide range of driv-
ing conditions such as extremely high
temperature areas or low temperature
areas like snow-covered roads. Accord-
ingly, you may hear light rattles from the
brake pad area when driving over a step,
which is not a malfunction. In addition,
you will hear creaks because of the
characteristics of the material for the disc
rotor. These creaks reduce with time and
wear.
Never park your vehicle for a long time
with the brake system wet.
The materials used for the brake disc
rotor and brake pads for specified NCCB
(NISSAN Carbon Ceramic Brake) are dif-
ferent from those used for the standard
brake system in GT-R. The rotor and pads
will be protected from adhesion caused
by rusting. However, never park your
vehicle for a long time with the brake
system wet. This helps maintain the brake
disc rotor and brake pads for a long time
and prevents an influence on the material
composition of the carbon ceramic rotor
and deterioration in the joint of brake disc
rotor’s full floating structure. Especially
during winter, be sure to park your vehicle
with the brake disc rotor and pads dry to
prevent them from being frozen and
damaged in below freezing temperature
conditions. The carbon ceramic brake forGT-R includes air bubbles in the rotor and
pads. Note that leaving them in the wet
condition tends to cause adhesion due to
freezing.
.
A screeching noise may be heard
when the brake pedal is depressed:
— When driving the vehicle for the first
time in the morning,
— After leaving the vehicle parked for extended periods of time, or
— When the vehicle is damp following rain showers or washing the vehi-
cle.
These sounds are normal. The noise is
caused when the brake pads absorb
moisture, and the noise stops after
the brake is applied several times.
. A screeching noise may also be heard
when the brake pedal is depressed:
— When repeatedly applying gentle
braking, especially on a curve at a
low speed, or
— When the brake rotors have circular scores with the brake temperature
high.
. The NCCB (NISSAN Carbon Ceramic
Brake) causes more screeching noise
in cold weather conditions than in
normal weather conditions.

back and as far-away as practical
from the steering wheel or instru-
ment panel. Always use the seat
belts.
. The driver and front passenger
seat belt buckles are equipped
with sensors that detect if the
seat belts are fastened. The Ad-
vanced Air Bag System monitors
the severity of a collision and seat
belt usage then inflates the air
bags as needed. Failure to prop-
erly wear seat belts can increase
the risk or severity of injury in an
accident.
. The front passenger seat is
equipped with an occupant clas-
sification sensor (pattern sensor)
that turns the front passenger air
bag OFF under some conditions.
This sensor is only used in this
seat. Failure to be properly
seated and wearing the seat belt
can increase the risk or severity
of injury in an accident.
(
“Front passenger air bag
and status light” page 1-42)
. Keep hands on the outside of the
steering wheel. Placing them in-
side the steering wheel rim could
increase the risk of hand injury if the supplemental front air bag
inflates.

WARNING
The front passenger air bag is de-
signed to automatically turn OFF
under some conditions. Read this
section carefully to learn how it
operates. Proper use of the seat,
seat belt and child restraints is ne-
cessary for most effective protec-
tion. Failure to follow all
instructions in this manual concern-ing the use of seats, seat belts and
child restraints can increase the risk
or severity of injury in an accident.
Status light:
The front passenger air bag status light
is located on the center instrument
panel. After the ignition switch is placed in
the ON position, the front passenger air
bag status light on the instrument panel
illuminates for about 7 seconds and then
turns off or illuminates depending on the
front passenger seat occupied status.
The light operates as follows:
. Unoccupied passenger seat: Thelight is OFF and the front passenger
air bag is OFF and will not inflate in a
crash.
. Passenger seat occupied by a small
adult, child or child restraint as out-
lined in this section: The
light
illuminates to indicate that the front
passenger air bag is OFF and will not
inflate in a crash.
. Occupied passenger seat and the
passenger meets the conditions out-
lined in this section: The
light is
OFF to indicate that the front passen-
ger air bag is operational. Front passenger air bag:

.If the vehicle becomes involved in
a collision but the pretensioner is
not activated, it is recommended
to have the pretensioner system
checked and, if necessary, re-
placed by a GT-R certified NISSAN
dealer.
. No unauthorized changes should
be made to any components or
wiring of the pretensioners. This
is to prevent damage to or acci-
dental activation of the preten-
sioners. Tampering with the
pretensioner system may result
in serious personal injury.
. Work around and on the preten-
sioners should be done by a GT-R
certified NISSAN dealer. Installa-
tion of electrical equipment
should also be done by a GT-R
certified NISSAN dealer. Un-
authorized electrical test equip-
ment and probing devices should
not be used on the pretensioners.
. If you need to dispose of a pre-
tensioner or scrap the vehicle, it is
recommended you contact a
GT-R certified NISSAN dealer. In-
correct disposal procedures
could cause personal injury. The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with
the seat belt retractor, it helps tighten the
seat belt when the vehicle becomes
involved in certain types of collisions,
helping to restrain front seat occupants.
The pretensioner is encased with the seat
belt retractor. These seat belts are used
the same way as conventional seat belts.
When a pretensioner activates, smoke is
released and a loud noise may be heard.
The smoke is not harmful, and it does not
indicate a fire. Care should be taken not
to inhale it as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air
promptly.
After pretensioner activation, load limiters
allow the seat belt to release webbing (if
necessary) to reduce forces against the
chest.
The supplemental air bag warning light
“Supplemental air bag warning light”
page 1-48 for more details.) If the opera-
tion of the supplemental air bag warning
light indicates there is a malfunction, it is
recommended you have the system
checked by a GT-R certified NISSAN deal-
er. When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s Man-
ual.
