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

If you have a flat tire, see the following
section. (
“FLAT TIRE” page 6-2)
CAUTION
A GT-R certified NISSAN dealer should
perform a tire change. It will be neces-
sary to reset the tire pressure sensors.
To change the tires, contact a GT-R
certified NISSAN dealer.
Be sure to use the tires and wheels together as
a set that are designated for use with this
vehicle.
When tire replacement is required, replacing the
tires as a set of four with new tires 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. Contact your GT-R certified
NISSAN dealer. They can recommend if an
individual tire or a complete set should be
replaced.TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pressure of all tires. When the low tire pressure
warning light is lit, one or more of your tires is
significantly under-inflated. The system also
displays pressure of all tires on the multi function
display by sending a signal from a sensor that is
installed in each wheel.
The TPMS will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h) .
Also, this system may not detect a sudden drop
in tire pressure. (
“Low tire pressure warn-
ing light” page 2-25) (
“TIRE PRESSURE
MONITORING SYSTEM (TPMS)” page 5-3)
(
“Flat tire” page 8-35)
Tire inflation pressureCheck the tire pressure often and always
prior to long distance trips. The recom-
mended tire pressure specifications are
shown on the F.M.V.S.S./C.M.V.S.S. label
or the Tire and Loading Information label (if
so equipped) under the “Cold Tire Pres-
sure” heading. The Tire and Loading
Information label is affixed to the driver
side door end. Tire pressures should be
checked regularly because:.
Most tires naturally lose air over time.
.
Tires can lose air suddenly when driven
over potholes or other objects or if the
vehicle strikes a curb while parking.
NOTE:. You can check the pressure of all four
tires on the multi function 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. Contact
a GT-R certified 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.The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or driven
less than 1 mile (1.6 km) at moderate
speeds.
Incorrect tire pressure, including un-
derinflation, may adversely affect tire
life and vehicle handling.
