2014 NISSAN GT-R brake light

The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, the VDC system helps to perform the
following functions.
.Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
. Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
. Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following
conditions:
— understeer (vehicle tends to not follow
the steered path despite increased
steering input)
— oversteer (vehicle tends to spin due to certain road or driving conditions) .
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel flashes
so note the following: .
The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
. You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
. Adjust your speed and driving to the road
conditions.
. The VDC mode can be changed using the
VDC setup switch. (

sion and suspension setup switches” page
5-24)
(
“Vehicle Dynamic Control (VDC) warning
light” page 2-31,“Vehicle Dynamic Con-
trol (VDC) off indicator light” page 2-32)
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
The VDC setup switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is off.
When the VDC setup switch is used to turn off
the system, the VDC system still operates to
prevent one drive wheel from slipping by
transferring power to a non slipping drive wheel.
The VDC warning light
flashes if this
occurs. All other VDC functions are off and the VDC warning light
will not flash. The VDC
system is automatically reset to on when the
ignition switch is placed in the off position then
back to the on position.
(
“Vehicle Dynamic Control (VDC) warning
light” page 2-31,“Vehicle Dynamic Con-
trol (VDC) off indicator light” page 2-32)
The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a “clunk” noise and/or feel
a pulsation in the brake pedal. This is normal and
is not an indication of a malfunction.
WARNING
. The VDC system is designed to help
the driver maintain stability but
does not prevent accidents due to
abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful
when driving and cornering on slip-
pery surfaces and always drive care-
fully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as

shock absorbers, struts, springs,
stabilizer bars, bushings and
wheels are not NISSAN approved
or are extremely deteriorated, the
VDC system may not operate prop-
erly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are
not standard equipment or are ex-
tremely deteriorated, the VDC warn-
ing light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the VDC warn-
ing light
may illuminate. Do not
drive on these types of roads.
. When driving on an unstable sur-
face such as a turntable, ferry, elevator or ramp, the VDC warning
light
may illuminate. This is not
a malfunction. Restart the engine
after driving onto a stable surface.
. If wheels or tires other than the
those recommended are used, the
VDC system may not operate prop-
erly and the VDC warning light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
NOTE:
. Always make sure the VDC is ON
before driving the vehicle by checking
that the VDC OFF indicator lights on
the meter and the VDC set-up switch
are not illuminated.
The GT-R is a high performance vehicle
and the VDC must be on/activated to
provide proper powertrain operation
and intended drivability.
WARNING
.The VDC OFF mode should ONLY be
used briefly to help free the vehicle
if stuck in snow or mud by tempora-
rily stopping operation of the VDC
to maintain wheel torque.
. Driving the GT-R with the VDC off
may lead to handling issues related
to steering maneuvers, acceleration,
or deceleration. Moreover, driving
with the VDC off can result in an
inoperative vehicle by causing ser-
ious damage to the powertrain,
including damage to the Transaxle
Assembly including Transfer, Clutch,
Gears, Transaxle case and all of its
components and other drivetrain
component(s) by overheating or ex-
cessive force.
. Damage to the powertrain or any
drivetrain component(s) that occurs
when there is a record in the Vehicle
Status Data Recorder (VSDR) that
the vehicle was driven with VDC off
during the period when the damage
was incurred is excluded from war-
ranty coverage.

Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal:Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Transmission
&Pmechanism: On a fairly
steep hill, check that your vehicle is held
securely with the shift lever in the
&Pposition
without applying any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, see a GT-R certified NISSAN dealer
immediately. Keep the floor mat away from the
pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only the
parking brake applied. If the parking brake needs
to be adjusted, see a GT-R certified NISSAN
dealer. Seat belts:
Check that all parts of the seat belt
system (for example, buckles, anchors, adjuster
and retractors) operate properly and smoothly,
and are installed securely. Check the belt
webbing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position.
Steering wheel: Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly and
in sufficient quantity when operating the heater
or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) . Battery*:
Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe condition require frequent checks of the
battery fluid level.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait at least 5 minutes for the oil to
drain back into the oil pan before checking the
oil.
Exhaust system: Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes in the engine compartment,
immediately have the exhaust system inspected
by a GT-R certified NISSAN dealer.

following section. (“Capacities and recom-
mended fuel/lubricants” page 9-2)
WARNING
. Use only new fluid from a sealed
container. Old, inferior or contami-
nated fluid may damage the brake
system. The use of improper fluids
can damage the brake system and
affect the vehicle’s stopping ability.
. Clean the filler cap before removing.
. Brake fluid is poisonous and should
be stored carefully in marked con-
tainers out of the reach of children.
CAUTION
Genuine NISSAN Brake Fluid R35 Spe-
cial II is the factory fill brake fluid. The
Vehicle Dynamic Control (VDC) unit and
other related parts were specially de-
signed for this brake fluid and NISSAN
cannot ensure proper operation of the
vehicle if other brake fluid is used.
NOTICE
Do not spill the fluid on any painted
surfaces. This will damage the paint. If
fluid is spilled, wash the surface with
water.
Check the fluid level in the reservoir. If the fluid is
below the MIN line
*1or the brake warning
light comes on, add Genuine NISSAN Brake
Fluid R35 Special II fluid up to the MAX line
*2.
If fluid must be added frequently, the system
should be checked by a GT-R certified NISSAN
dealer.
Maintenance and do-it-yourself8-15
BRAKE FLUID

If the brakes do not operate properly, have the
brakes checked by a GT-R certified NISSAN
dealer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes.
The disc-type brakes self-adjust every time the
brake pedal is applied.
WARNING
See a GT-R certified NISSAN dealer for
a brake system check if the brake pedal
height does not return to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear warn-
ings. 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 more wear of the brake pad,
the sound will always be heard even if the brake
pedal is not depressed. Have the brakes
checked as soon as possible if the wear warning
sound is heard.
Under some driving or climate conditions,occasional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does not
affect the function or performance of the brake
system.
Proper brake inspection intervals should
be followed.
For additional information, see the
maintenance log section of your NISSAN
Service and Maintenance Guide for mainte-
nance intervals.
HIGH PERFORMANCE BRAKE SYS-
TEM
This vehicle is equipped with high performance
brake pads that provide appropriate braking
force in a broad range of driving environments.
Due to the material used for the brake pads, the
road wheels may become more easily covered
by brake dust, however this does not indicate
that there is a malfunction.
The GT-R brake pads use material that contains
a lot of iron to maintain steady braking perfor-
mance even in high and low temperatures.
However, if the brake system is wet and the
parking brake is applied for a long time, the iron
in this material may get rusty and the brake pad
and disc rotor may be fixed together. This may
cause noise and vibration while driving. Before
parking the vehicle, dry the brake by driving on a dry road, especially after washing the vehicle or
driving in rain. Contact a GT-R certified NISSAN
dealer if the noise and vibration continue.
Frequent hard braking may cause scorching of
the brake pads. This will require the brake pads
to be replaced, even if the wear limit has not
been reached. Have the brake pads and disc
rotors inspected at the regular vehicle inspec-
tions.
For more details, contact a GT-R certified
NISSAN dealer.
REPLACING THE BRAKE PADS
NISSAN generally recommends to replace all
four sets of brake pads and disc rotors at the
same time to maintain maximum brake perfor-
mance.
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 technician 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.
Maintenance and do-it-yourself8-23
BRAKES

8-24Maintenance and do-it-yourself
If the inside of the disc rotors are cold during the
winter and the surface becomes 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 repeatedly
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. Contact a GT-R
certified NISSAN dealer for replacement.
ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than that specified on
the fuse box cover. This could damage
the electrical system or cause a fire.
If any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition switch is pushed to the OFF or LOCK position and the headlight
switch is turned to OFF. 2. Open the engine hood and remove the
cover on the battery and the fuse/fusible link
holder.
3. Remove the fuse/fusible link holder cover.
4. Remove the fuse with the fuse puller that is located in the engine compartment fuse box.
FUSES

8-42Maintenance and do-it-yourself
changer, cracks and deformation
may occur on the bead portion of
the tires meaning that the tires
cannot be reused.
. Make sure the tire valve stem cap is
installed and that the valve stem is
tight. When installing the cap, make
sure to tighten the cap by hand. If a
tool is used to tighten the cap, the
cap may be damaged.
WARNING
.The use of tires other than those
specified or the mixed use of tires of
different brands, construction (bias,
bias-belted, radial or run-flat) , or
tread patterns can adversely affect
the ride, braking, VDC system, hand-
ling, ground clearance, body-to-tire
clearance, tire chain clearance,
speedometer calibration, headlight
aim and bumper height. Some of
these effects may lead to accidents
and could result in serious personal
injury.
. If the wheels are changed for any
reason, always replace with wheels which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics, affect the VDC system and/or
cause interference with the brake
discs. Such interference can lead to
decreased braking efficiency and/or
early brake pad wear. (
“Wheels
and tires” page 9-9)
. When a wheel is replaced, tire
pressure will not be indicated, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute and
remain on after the 1 minute. Con-
tact a GT-R certified NISSAN dealer
as soon as possible for tire replace-
ment and/or system resetting.
. Replacing tires with those not ori-
ginally specified by NISSAN could
affect the proper operation of the
TPMS.
. Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning. .
Never use retread tires.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information” (US) or “Tire
Safety Information” (Canada) in the
Warranty Information Booklet.
. Always use tires of the specified
type, size, brand, construction (bias,
bias-belted, radial or run-flat) , and
tread pattern on all four wheels.
Failure to do so may result in a
circumference difference between
tires on the front and rear axles
which will cause excessive tire wear
and may damage the transmission,
transfer case and differential gears.
Wheel balance
Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the rear wheels on the vehicle could lead to
mechanical damage.
For additional information regarding tires, refer
