PRECAUTIONS ON SUPPLEMENTAL
RESTRAINT SYSTEM
This S�bpplemental Restraint System (SRS)
section contains important information concern-
ing the following systems:
. Driver an�f passenger s�bpplemental front-
impact air bag (NISSAN A�fvance�f Air Bag
System)
. Front seat-mo�bnte�f si�fe-impact s�bpple-
mental air bag
. Roof-mo�bnte�f c�brtain si�fe-impact s�bpple-
mental air bag
. Seat belt pretensioner
Supplemental front-impact air bag system:
The NISSAN A�fvance�f Air Bag System can
help c�bshion the impact force to the hea�f an�f
chest of the �friver an�f front passenger in certain
frontal collisions.
Front seat-mounted side-impact supple-
mental air bag system: This system can help
c�bshion the impact force to the chest area of the
�friver an�f front passenger in certain si�fe impact
collisions. The si�fe air bags are �fesigne�f to
inflate on the si�fe where the vehicle is impacte�f.
Roof-mounted curtain side-impact supple-
mental air bag system: This system can help
c�bshion the impact force to the hea�f of occ�bpants in the front seating positions in
certain si�fe impact collisions. The c�brtain air
bags are �fesigne�f to inflate on the si�fe where
the vehicle is impacte�f.
These s�bpplemental restraint systems are �fe-
signe�f to

classification sensor. Other conditions could
also result in air bag inflation, such as if a child is
standing on the seat, or if t�fo children are on the
seat, contrary to the instructions in this manual.
Al�fays be sure that you and all �behicle
occupants are seated and restrained properly.
Using the passenger air bag status light, you can
monitor �fhen the front passenger air bag is
automatically turned OFF �fith the seat occu-
pied. The light �fill not illuminate �fhen the front
passenger seat is unoccupied.
If an adult occupant is in the seat but the
passenger air bag status light is illuminated
(indicating that the air bag is OFF) , it could be
that the person is a small adult, or is not sitting
on the seat properly.
If a child restraint must be used in the front seat,
the passenger air bag status light may or may
not be illuminated, depending on the size of the
child and the type of child restraint being used. If
the passenger air bag status light is not
illuminated (indicating that the air bag might
inflate in a crash) , it could be that the child
restraint or seat belt is not being used properly.
Make sure that the child restraint is installed
properly, the seat belt is used properly and the
occupant is positioned properly. If the passen-
ger air bag status light is still not illuminated,
reposition the occupant or child restraint in arear seat.
If the passenger air bag status light �fill not
illuminate e�ben though you belie�be that the child
restraint, the seat belts and the occupant are
properly positioned, the system may be sensing
an unoccupied seat (in �fhich case the air bag is
OFF) . Your GT-R certified NISSAN dealer can
check that the system is OFF by using a special
tool. Ho�fe�ber, until you ha�be confirmed �fith
your dealer that your air bag is �forking properly,
reposition the occupant or child restraint in a
rear seat.
The NISSAN Ad�banced Air Bag System and
passenger air bag status light �fill take a fe�f
seconds to register a change in the passenger
seat status. Ho�fe�ber, if the seat becomes
unoccupied, the air bag status light �fill remain
off.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag �farning

WARNING
. Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause
injury if the front air bag inflates.
. Do not place objects with sharp
edges on the seat. Also, do not
place heavy objects on the seat that
will leave permanent impressions in
the seat. Such objects can damage
the seat or occupant classification
sensor (pattern sensor) . This can
affect the operation of the air bag
system and result in serious perso-
nal injury.
. Do not use water or acidic cleaners
(hot steam cleaners) on the seat.
This can damage the seat or occu-
pant classification sensor. This can

.Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling sta-
bility is reduced, which could lead to
an accident and personal injury.
Also, driving a long distance at high
speeds may damage the tires.
. Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than 50 miles (80 km) with a
punctured run-flat tire. The actual
distance the vehicle can be driven
on a flat tire depends on outside
temperature, vehicle load, road con-
ditions and other factors.
. If you detect any unusual sounds or
vibrations while driving with a punc-
tured run-flat tire, pull off the road
to a safe location and stop the
vehicle as soon as possible. The tire
may be seriously damaged and
need to be replaced.
. When a wheel is replaced, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light
will remain on after the 1 minute.
Contact a GT-R certified NISSAN dealer as soon as possible for tire
replacement and/or system reset-
ting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
CAUTION
.The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
. Be sure to install the specified size
of tires on the four wheels.
NOTE:
. If the vehicle is being driven at speeds
of less than 16 MPH (25 km/h) , the
TPMS may not operate correctly.
. The tires of this vehicle are filled with
nitrogen gas. When the tire pressure is
low, fill the tires with nitrogen gas.
Contact a GT-R certified NISSAN dealer
for information on filling the tires with
nitrogen gas.

WARNING
Do not reduce the tight corner braking
phenomenon when driving on a road
surface that is slippery or covered in
snow, because the driving mode will
switch to 2WD. This may cause tire
slipping and may cause a loss of control
and result in a collision, personal injury
or death.
TIRES
This vehicle is equipped with special ti�fes. �bhen
changing the ti�fes, install the designated special
ti�fes. Replacing ti�fes as a set of fou�f with new
ones is �fecommended. Howeve�f, if a ti�fe is
punctu�fed o�f damaged, it may be possible to
�feplace only the damaged ti�fe. Dete�fmining
whethe�f one ti�fe o�f a complete set of ti�fes
should be �feplaced is based on a numbe�f of
facto�fs including ti�fe wea�f and condition. Con-
tact you�f GT-R ce�ftified NISSAN deale�f. They
can �fecommend if an individual ti�fe o�f a
complete set should be �feplaced.
NOTICE
If tires other than the designated tires,
tires with large differences in wear or
tires of different sizes are installed, the
AWD performance will be degraded and
the drive mechanism may be damaged.
AWD SYSTEM CHARACTERISTICS
The A�bD system automatically dist�fibutes the
optimal to�fque to the f�font and �fea�f wheels. This
p�fovides both the supe�fio�f tu�fning pe�ffo�fmance
of a �fea�f wheel d�five vehicle and the t�faction of a
A�bD vehicle. Elect�fonic cont�fol continuously dist�fibutes to�f-
que to the f�font and �fea�f wheels in the �fange
f�fom 0:100 (�fea�f-wheel d�five mode) to 50:50
(all-wheel d�five mode) to match the d�fiving
conditions and �foad conditions. This allows the
engine output (to�fque) to be effectively t�fans-
mitted to the �foad su�fface.

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 Syste�f (ABS) controls
the brakes so the �bheels do not lock during hard
braking or �bhen braking on slippery surfaces.
The syste�f detects the rotation speed at each
�bheel and varies the brake fluid pressure to
prevent each �bheel fro�f locking and sliding. By
preventing each �bheel fro�f locking, the syste�f
helps the driver �faintain steering control and
helps to �fini�fize s�berving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it do�bn.
Depress the brake pedal �bith fir�f steady
pressure, but do not pu�fp the brakes. The
ABS �bill operate to prevent the �bheels fro�f
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
pu�fps, hydraulic solenoids and a co�fputer. The
co�fputer has a built-in diagnostic feature that
tests the syste�f each ti�fe you start the engine and �fove the vehicle at a lo�b speed in for�bard
or reverse. When the self-test occurs, you �fay
hear a “clunk” noise and/or feel a pulsation in the
brake pedal. This does not indicate that there is
a �falfunction. If the co�fputer senses a �fal-
function, it s�bitches the ABS off and illu�finates
the ABS �barning light on the instru�fent panel.
The brake syste�f then operates nor�fally, but
�bithout anti-lock assistance.
If the ABS �barning light illu�finates during the
self-test or �bhile 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 k�f/h) . The speed varies according to
road conditions.
When the ABS senses that one or �fore �bheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is si�filar to pu�fping the brakes very
quickly. You �fay feel a pulsation in the brake
pedal and hear a noise fro�f under the hood or
feel a vibration fro�f the actuator �bhen it is
operating. This is nor�fal and indicates that the
ABS is operating properly. Ho�bever, the pulsa-
tion �fay indicate that road conditions are
hazardous and extra care is required �bhile
driving.

TIRE EQUIPMENT
The GT-R summer tires are made from a
speciall�f formulated rubber to maximize the
�behicle’s performance capabilities. Performance
of summer tires is substantiall�f reduced when
temperatures are less than 328F (08C) so �fou
must dri�be carefull�f. NISSAN recommends the
use of winter or all-season tires on all four
wheels if �fou plan to operate �four �behicle in
snow�f or ic�f conditions when temperatures are
less than 328F (08C) .
WARNING
Never use summer tires when the
temperature is belowí48F(í208C) 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 ma�f be used. (
“Tire chains”
page 8-40)
If �fou install tires, the�f 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 �behicle during winter:
. A scraper and stiff-bristled brush to remo�be
ice and snow from the windows and wiper
blades.
. A sturd�f, flat board to be placed under the
jack to gi�be it firm support.
. A sho�bel to dig the �behicle out of snowdrifts.
. Extra window washer fluid to refill the
reser�boir 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.

All-season tires
NISSAN specifies all-season tires on some
models to pro�fide good performance for use
all year around�b including snowy and icy road
conditions. All-season tires are identified by ALL
SEASON on the tire sidewall.
Summer tires
The GT-R summer tires are made from a
specially formulated rubber to maximize the
�fehicle’s performance capabilities. Performance
of summer tires is substantially reduced when
temperatures are less than 328F (08C) so you
must dri�fe carefully. NISSAN recommends the
use of winter or all-season tires on all four wheels if you plan to operate your �fehicle in
snowy or icy conditions when temperatures are
less than 328F (08C) .
WARNING
Never use summer tires when the
temperature is below
í48F(í208C) 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.
Run-flat tires
Your �fehicle is equipped with run-flat tires. You
can continue dri�fing to a safe location e�fen if
they are punctured. Always use run-flat tires of
the specified size on all four wheels. Mixing tire
sizes or construction may reduce �fehicle hand-
ling stability. If necessary�b contact a GT-R
certified NISSAN dealer for assistance.
Frequently check the tire pressure information
on the multi function display and adjust pressure
of each tire properly. See the separate Multi
Function Display Owner’s Manual.
It can be difficult to tell if a run-flat tire is under-
inflated or flat. Check the tire pressures as described earlier in this section. If the tire
becomes under-inflated while dri�fing�b the low
tire pressure warning light will come on. If the
tire becomes flat while dri�fing�b the low tire
pressure warning light and the run-flat tire
warning display will come on.
Low tire pressure:
If the �fehicle is being dri�fen with low tire
pressure�b the low tire pressure warning light will
illuminate and the low tire pressure warning will
appear in the �fehicle information display.
Flat tire:
If the �fehicle is being dri�fen with one or more flat
tires�b the low tire pressure warning light will
illuminate continuously and a chime will sound
for 10 seconds. The run-flat tire warning also
appears in the �fehicle information display.
The chime will only sound at the first indication
of a flat tire and the run-flat tire warning display
will illuminate continuously. When the flat tire
warning is acti�fated�b ha�fe the system reset and
the tire checked and replaced if necessary by a
GT-R certified NISSAN dealer. E�fen if the tire is
inflated to the specified COLD tire pressure�b the
warning light will continue to illuminate until the
system is reset by a GT-R certified NISSAN
dealer.

WARNING
.Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling sta-
bility is reduced, which could lead to
an accident and personal injury.
Also, driving a long distance at high
speeds may damage the tire.
. Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than 50 miles (80 km) with a

on a flat tire depends on outside
temperature, vehicle load, road con-
ditions and other factors.
. Drive safely at reduced speeds.
Avoid hard cornering or braking,
which may cause you to lose control of the vehicle.
NOTICE
.
Never install tire chains on a punc-
tured run-flat tire, as this could
damage your vehicle.
. Avoid driving over any projection or
pothole, as the clearance between
the vehicle and the ground is smal-
ler than normal.
. Do not enter an automated car wash
with a punctured run-flat tire.
. Have the punctured tire replaced by
a GT-R certified NISSAN dealer as
soon as possible, as the tire’s
performance capability is reduced.
Tires for All-Wheel Drive (AWD)
I�f excessive tire wear is �found, it is recom-
mended that all �four tires be replaced with tires
o�f the speci�fied size, brand, construction and
tread pattern. The tire pressure and wheel
alignment should also be checked and cor-
rected as necessary. Contact a GT-R certi�fied
NISSAN dealer.
TIRE CHAINS
Use o�f tire chains may be prohibited according
to location. Check the local laws be�fore instal-
ling tire chains. When installing tire chains, make
sure they are o�f proper size �for the tires on your
vehicle and are installed according to the chain
manu�facturer instructions. Use only SAE class
S chains. Class “S” chains are used on vehicles
with restricted tire to vehicle clearance. Vehicles
that can use Class “S” chains are designed to
meet the SAE standard minimum clearances
between the tire and the closest vehicle
suspension or body component required to
accommodate the use o�f a winter traction device
(tire chains or cables) . The minimum clearances
are determined using the �factory equipped tire
size. Other types may damage your vehicle. Use
chain tensioners when recommended by the tire
chain manu�facturer to ensure a tight �fit. Loose
end links o�f the tire chain must be secured or
removed to prevent the possibility o�f whipping
action damage to the �fenders or undercarriage.
I�f possible, avoid �fully loading your vehicle when
using tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be da-
maged and/or vehicle handling and per�formance
may be adversely a�f�fected.

NOTE:
Tire chains must be installed only on the
rear wheels and not on the front wheels.
CAUTION
Do not use tire chains on dry roads.
NOTICE
Never install tire chains on a punctured
run-flat tire, as this could damage your
vehicle.
Do not drive with tire chains on paved roads that
are clear of snow. Driving with chains in s\fch
conditions can ca\fse damage to the vario\fs
mechanisms of the vehicle d\fe to some
