5-42Starting and driving
If any malfunction occurs in the AWD system
while the engine is running, the warning light will
come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high AWD clutch temperature. The
driving mode may change to two-wheel drive.
If the warning light blinks rapidly during opera-
tion, stop the vehicle with the engine idling in a
safe place immediately. Then if the light goes off
after a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning light
blink slowly (about once per two seconds) . Pull
off the road in a safe area, and idle the engine.
Check that all tire sizes are the same, tire
pressure is correct and tires are not worn and
winter tires are not installed on the front or rear
wheels only.
If the warning light is blinking after the above
operation, it is recommended you have your
vehicle checked by a GT-R certified NISSAN
dealer as soon as possible.
If non-genuine GT-R tires are used, the warning
light may illuminate. (
ªGT-R special pre-
cautionsº page GTR-5)
WARNING
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any drive or reverse
position with the engine running.
Doing so may result in drivetrain
damage or unexpected vehicle
movement which could result in
serious vehicle damage or personal
injury.
. Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment even if the other two wheels
are raised off the ground. Make sure
that you inform the test facility
personnel that your vehicle is
equipped with AWD before it is
placed on a dynamometer. Using
the wrong test equipment may re-
sult in drivetrain damage or unex-
pected vehicle movement which
could result in serious vehicle da-
mage or personal injury.
NOTICE
.If the warning light comes on while
driving there may be a malfunction
in the AWD system. Reduce the
vehicle speed and it is recom-
mended you have your vehicle
checked by a GT-R certified NISSAN
dealer as soon as possible.
. If the warning light remains on after
the above operation, it is recom-
mended you have your vehicle
checked by a GT-R certified NISSAN
dealer as soon as possible.
. The powertrain may be damaged if
you continue driving with the warn-
ing light blinking.
. Do not spin the rear wheels while
driving. Spinning the rear wheels
may increase the temperatures of
the AWD clutch system and damage
the system. Adjust the accelerator
pedal position to stop wheel spin.

TIGHT CORNER BRAKING PHE-
NOMENON
GUID-1A27E22E-DFCE-4A37-87A5-5B6E52FE9B38If the steering wheel is turned more than half a
turn when the vehicle is started when it is cold, it
may be harder to move the vehicle forward and
backward. This phenomenon is known as the
ªtight corner braking phenomenonº.
This phenomenon is unique to AWD vehicles,
and occurs due to a difference in speeds
between the front and rear wheels while the
vehicle is turning. This does not indicate that
there is a malfunction.
NOTE:
If the tight corner braking phenomenon
occurs, a slipping sound may be heard
from the tires, or a squeaking sound may
be heard from the drive system.
Reducing tight corner braking phe-
nomenon
GUID-BA737537-EE7C-4157-9184-AAED4280FA70The tight corner braking phenomenon can be
reduced if the following three conditions are
met:
.Transmission setup switch is set to Normal
mode.
. Vehicle speed is low (less than approxi-
mately 6 MPH (10 km/h)) . .
The steering wheel is turned more than 1/2
turn.
TIRESGUID-4607560A-BD7E-4BAE-972E-CBDBA63C2F98This vehicle is equipped with special tires. When
changing the tires, install the designated special
tires. Replacing tires as a set of four with new
ones is recommended. However, if a tire is
punctured or damaged, it may be possible to
replace only the damaged tire. Determining
whether one tire or a complete set of tires
should be replaced is based on a number of
factors including tire wear and condition. Con-
tact your GT-R certified NISSAN dealer. They
can recommend if an individual tire or a
complete set should be replaced.
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 CHARACTERISTICSGUID-BB073156-8A99-484C-B5C5-853EDBCA9D09The AWD system automatically distributes the
optimal torque to the front and rear wheels. This
provides both the superior turning performance
of a rear wheel drive vehicle and the traction of a
AWD vehicle.
Electronic control continuously distributes tor-
que to the front and rear wheels in the range
from 0:100 (rear-wheel drive mode) to 50:50
(all-wheel drive mode) to match the driving
conditions and road conditions. This allows the
engine output (torque) to be effectively trans-
mitted to the road surface.

ANTI-LOCK BRAKING SYSTEM
(ABS)
GUID-880D61BF-CE2F-4B51-81CD-698ABEB3F895
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 System (ABS) controls
the brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the systemGUID-6ECE2B5D-7A4F-458B-88D2-671A03E2B8FEDepress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
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 featureGUID-C37F4BC5-8CBA-4D29-801E-112190163058The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you may
hear a ªclunkº noise and/or feel a pulsation in the
brake pedal. This does not indicate that there is
a malfunction. If the computer senses a mal-
function, it switches the ABS off and illuminates
the ABS warning light on the meter. The brake
system then operates normally, but without anti-
lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, it is recommended you
have the vehicle checked by a GT-R certified
NISSAN dealer.
Normal operationGUID-A2598887-97F1-4229-825A-30AB7D1015CCThe ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h) . The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or

8-4Maintenance and do-it-yourself
GUID-3E2B76F7-5036-45A1-A71E-B1240A4ECE40During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or it is
recommended you have a GT-R certified
NISSAN dealer do it promptly. In addition, you
should notify a GT-R certified NISSAN dealer if
you think that repairs are required.

EXPLANATION OF MAINTENANCE
ITEMS
GUID-86F8A64E-0E92-4949-8242-B20713B799A0Additional information on the following
items with ª*º is found later in this section.
Outside the vehicleGUID-95B37F87-9545-4A90-8719-22BF60997173The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood:Check that all doors
and the engine hood, operate properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary latch
keeps the hood from opening when the primary
latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication frequently. Lights*:
Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires cannot be rotated because
your vehicle is equipped with different sized tires
in the front and rear.
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If
necessary, adjust the pressure in all tires to the
pressure specified. Check carefully for damage,
cuts or excessive wear.
NOTE:
. You can check the pressure of all four
tires on the touch screen display. See
the separate Multi Function Display
Owner's Manual.
. The tires of this vehicle are filled with
nitrogen gas. When the tire pressure is
low, fill the tires with nitrogen. It is
recommended you contact a GT-R cer-
tified NISSAN dealer for information on
filling the tires with nitrogen. .
If nitrogen is not available, compressed
air may be safely used under normal
driving conditions. However, NISSAN
recommends refilling with nitrogen for
maximum tire performance.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace grommet
seal of transmitter in TPMS, when replacing
each tire by reaching the wear limit.
Tire, wheel alignment and balance: If the
vehicle should pull to either side while driving on
a straight and level road, or if you detect uneven
or abnormal tire wear, there may be a need for
wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer
to ªImportant Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada) in the War-
ranty Information Booklet.
Windshield: Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a
damaged windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.

CHECKING THE TIRE PRESSUREGUID-9660404A-CCE9-48DF-B05F-387147B1D4CA1.Remove the valve stem cap from the
tire.
2.Press the pressure gauge squarely
onto the valve stem. Do not press too
hard or force the valve stem side-
ways, or air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure,
reposition the gauge to eliminate this
leakage.
3.Remove the gauge.
4.Read the tire pressure on the gauge
stem and compare it to the specifica-
tion shown on the Tire and Loading
Information label.
5.Add air to the tire as needed. If too
much air is added, press the core of
the valve stem briefly with the tip of
the gauge stem to release pressure.
Recheck the pressure and add or
release air as needed.
6.Install the valve stem cap.
7.Check the pressure of all other tires.
NOTE:
.
You can check the pressure of all
four tires on the touch screen
display. See the separate Multi
Function Display Owner's Man-
ual.
.The tires of this vehicle are filled
with nitrogen gas. When the tire
pressure is low, fill the tires with
nitrogen. It is recommended you
contact a GT-R certified NISSAN
dealer for information on filling
the tires with nitrogen.
.If nitrogen is not available, com-
pressed air may be safely used
under normal driving conditions.
However, NISSAN recommends
refilling with nitrogen for max-
imum tire performance.

TIRE LABELINGGUID-8E9A4B6A-A510-4A34-B395-913A59699343
Federal law requires tire manufacturers
to place standardized information on the
sidewall of all tires. This information
identifies and describes the fundamental
characteristics of the tire and also
provides the tire identification number
(TIN) for safety standard certification.
The TIN can be used to identify the tire
in case of a recall.
