SUMMER TIRES
The GT-R summer tires are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. Performance
of summer tires is substantially reduced �bhen
temperatures are less than 328F (08C) so you
must drive carefully. NISSAN recommends the
use of �binter or all-season tires on all four
�bheels if you plan to operate your vehicle in
sno�by or icy conditions �bhen 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.
ALL-SEASON TIRES
Do not exceed the speed rating of the tire that is
installed on the vehicle.
AVOIDING BODY DAMAGE
The GT-R bumper, fascia, side sills and under-
carriage are close to the ground. Drive slo�bly on
rough or uneven roads to avoid damaging these
parts. Pay careful attention to �bheel bloc�fs and
curbs. If the front bumper contacts a �bheel
bloc�f, curb, etc., the bumper and underlying
parts may be damaged or crac�fed. Be careful
not to damage the front spoiler that is installed
belo�b the engine room.

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.

BRAKING PRECAUTIONS
The brake system has two separate hydra�flic
circ�fits�b If one circ�fit malf�fnctions, yo�f will still
have braking at two wheels�b
Yo�f may feel a small click and hear a so�fnd
when the brake pedal is f�flly depressed slowly�b
This is not a malf�fnction and indicates that the
brake assist mechanism is operating properly�b
Vacuum assisted brakes
The brake booster aids braking by �fsing engine
vac�f�fm�b If the engine stops, yo�f can stop the
vehicle by depressing the brake pedal�b However,
greater foot press�fre on the brake pedal will be
req�fired to stop the vehicle and the stopping
distance will be longer�b
Wet brakes
When the vehicle is washed or driven thro�fgh
water, the brakes may get wet�b As a res�flt, yo�fr
braking distance will be longer and the vehicle
may p�fll to one side d�fring braking�b
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-�fp
the brakes�b Do this �fntil the brakes ret�frn to
normal�b Avoid driving the vehicle at high speeds
�fntil the brakes f�fnction correctly�b
Using the brakes
Avoid resting yo�fr foot on the brake pedal while
driving�b This will ca�fse overheating of the
brakes, wearing o�ft the brake and pads faster
and red�fce gas mileage�b
To help red�fce brake wear and to prevent the
brakes from overheating, red�fce speed and
downshift to a lower gear before going down a
slope or long grade�b Overheated brakes may
red�fce braking performance and co�fld res�flt in
loss of vehicle control�b
WARNING
.While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an
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-IN
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
dr�fms/rotors are replaced, in order to ass�fre the
best braking performance�b
This proced�fre is described in the vehicle
service man�fal and can be performed by a
GT-R certified NISSAN dealer�b
BRAKE SYSTEM

LOCATIONS

8-12Maintenance and do-it-yourself
This vehicle contains Genuine N�fSSAN Lon�b
Life Antifreeze/Coolant (blue) . The life expec-
tancy of the factory-fill coolant is 24,000 miles
(38,400 km) or 2 years. Mixin�b any other type of
coolant or the use of non-distilled water will
reduce the life expectancy of the factory-fill
coolant. Refer to the GT-R Service and Main-
tenance Guide for more details.
If the cooling system frequently requires
coolant, have it checked by a GT-R certified
NISSAN dealer.
Check that the level of coolant is between MAX
and M�fN on the pressurized radiator reservoir. �ff
the level is below the midpoint, the amount of
coolant circulatin�b may be insufficient for max-
imum vehicle performance, possibly causin�b
en�bine overheatin�b or other trouble.
For the coolant level and mixture ratio when
en�ba�bin�b in performance drivin�b, see
“Coolant level and mixture ratio” pa�be
GTR-15.
Except for NISMO models:
�ff it is difficult to determine the midpoint between
MAX and M�fN, remove the coolant reservoir cap
and look inside throu�bh the openin�b to check
that the coolant level is above the divider
*3
between the top half and bottom half of the
pressurized coolant reservoir.
NOTICE
. The coolant reservoir is equipped
with a pressure type cap, and the
radiator is equipped with a non-
pressure type cap. Do not switch
the radiator filler cap and the cool-
ant reservoir cap. Doing so will
cause substandard cooling perfor-
mance and overheating.
. If you have added only water as the
coolant in an emergency, change it
to a coolant mixture ratio specified
as soon as possible.
CHANGING ENGINE COOLANT
�ff major coolin�b system repairs are required,
contact a GT-R certified N�fSSAN dealer. The
service procedures can be found in the appro-
priate N�fSSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
.To avoid the danger of being
scalded, never change the coolant
when the engine is hot.
. Never remove the radiator filler cap
and the coolant reservoir cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator and
reservoir.
. Avoid direct skin contact with used
coolant. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible.
. Keep coolant out of reach of chil-
dren and pets.
En�bine coolant must be disposed of properly.
Check your local re�bulations.
