WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.Vacuum assisted brakesThe brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.Wet brakesWhen the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.
Using the brakesAvoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and pads faster
and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
. While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheelstoskidandresultinan
accident.
. If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.

PARKING BRAKE BREAK-INBreak in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual and can be performed by a
GT-R certified NISSAN dealer.
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.
Alwaysmaintainasafedistance
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 systemDepress 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 featureThe 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 “clunk” 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 instrument panel.
The brake system then operates normally, but
without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a GT-R certified NISSAN dealer.Normal operationThe 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
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.
The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving situa-
tions, the system will control braking and engine
output to help keep the vehicle on its steered
path.
.The VDC mode can be changed using the
VDC setup switch. (
“VDC, TRANS-
MISSION AND SUSPENSION SETUP
SWITCHES” page 5-21)
. When the VDC system is operating, the
indicator in the instrument panel blinks.
. If the
indicator blinks, the road condi-
tions may be slippery. Be sure to adjust your
speed and driving to these conditions. Be
sure to drive carefully. (
“Slip indicator
light” page 2-29) (
“Vehicle Dynamic
Control (VDC) off indicator light” page 2-
29)
. Indicator light
If a malfunction occurs in the system, the
and
indicator lights illuminate in
the instrument panel. As long as these
indicators are illuminated, the VDC system
function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) function to improve vehicle traction.
The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The ABLS system brakes the spinning wheel, which
distributes the driving power to the other drive
wheel. If the vehicle is operated with the VDC
setup switch pushed and the VDC system
turned off, all VDC systems will be turned off.
The ABLS system and ABS will still operate with
the VDC system off.
While the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise
or feel a vibration from under the hood. This is
normal and indicates that the VDC system is
working properly.
The VDC system 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 forward or backward. When the
self-test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal. This
does not indicate that there is a malfunction.
WARNING
.
The VDC system is designed to help
improve driving stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
due to careless or dangerous driv-
ing techniques. Reduce vehicle
speed and be especially careful
when driving and cornering on slip-
pery surfaces and always drive care-

. If engine related parts such as
muffler are not standard equipment
or are extremely deteriorated, the
indicator or
indicator or
both indicator lights may illuminate.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars and bushings are
not NISSAN approved or are extre-
mely deteriorated the VDC system
may not operate properly. This could
adversely affect vehicle handling
performance, and the
indicator

. If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the
indicator
or
indicator or both indicator
lights may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the
in-
dicator or
indicator or both indicator lights may illuminate. Do
not drive on these types of roads.
. When driving on unstable surfaces
such as a turntable, ferry, elevator
or ramp, the
indicator or
indicator or both indicator lights
may illuminate. This does not indi-
cate that there is a malfunction.
Restart the engine after driving onto
a stable surface.
. If wheels or tires other than those
recommended are used, the VDC
system may not operate properly
and the
indicator or
in-
dicator or both indicator lights may
illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
NOTE:.Make sure VDC is on before driving the
vehicle. The VDC OFF mode is an
emergency mode to help free a vehicle
stuck in mud or snow by temporarily
stopping VDC operation and keeping
torque on the wheels.
. When attempting to free the vehicle
from mud or fresh snow, the VDC will detect the tire slipping, and the engine
speed may not increase even when the
accelerator pedal is depressed. To raise
the engine speed, use the VDC set up
switch to turn the VDC system OFF.
. When the VDC system is turned OFF,
all VDC functions (including traction
control) , except for the ABS functions,
are deactivated.

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.
ENGINE BLOCK HEATER (if so
equipped)Engine block heaters are available through
NISSAN dealers to assist in cold temperature
starting. The engine block heater should be
used when the outside temperature is 20 8F
( 78C) or lower.To use the engine block heater1. Turn the engine off.
2. Open the hood and unwrap the engine
block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded 110-
volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours, depending on
outside temperatures, to properly warm the
engine coolant. Use an appropriate timer to
turn the engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away from
moving parts.
WARNING
.Do not use your engine block heater
with an ungrounded electrical sys-
tem or a 2-pronged adapter. You can
be seriously injured by an electrical
shock if you use an ungrounded
connection.

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.
. 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
your GT-R certified NISSAN dealer
as soon as possible, as the tire’s
performance capability is reduced.
If you have a flat tire and have to stop the
vehicle, follow the instructions below.
1. Safely move the vehicle off the road and away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to the
&Pposition.
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
