Nissan 2011 GT-R Automobile User Manual


 
Black plate (19,1)
Model "R35-D" EDITED: 2009/ 12/ 11
brakes are applied when the vehicle is
shut off, the rotor and pads can rust
together, even when the brake pads are
dry.
If the brakes are wet when the vehicle is
parked and the parking brake is applied
for a long time.
The hill start assist system can apply the
brakes even if the brake pedal is not
depressed. The brake pads and rotors
can rust together if the parking proce-
dure previously described is not fol-
lowed.
Contact a GT-R certified NISSAN dealer if
the brake pads and brake rotor have rusted
together.
NOTICE
Have the brake pads and/or rotors
quenched when the brake pads are
replaced to reduce the possibility of
the rotors and brake pads rusting. For
detailed information about quenching,
contact a GT-R certified NISSAN dealer.
. To maintain steady braking performance in
both extremely high and low temperatures,
the gap between the brake pad and caliper
is larger than normal and large-size brake
pads are used. When driving over a bump, a
light rattling sound may be heard from the
brake pad. This does not indicate that there
is a malfunction.
. When the brake disc rotor undergoes
thermal expansion, a ticking noise may be
heard from the engaging portion of the
wheel and the brake disc rotor. This does
not indicate that there is a malfunction. The
noise will reduce when the temperature
decreases.
. In addition to noise resulting from uneven
tire wear discussed in the previous section,
the GT-R tires are more rigid than a typical
passenger car tire and are made from a
specially formulated rubber to maximize the
vehicle’s performance capabilities. These
characteristics cause the GT-R tires to have
more road noise than a typical passenger
car tire. This road noise is normal.
. Due to the performance capabilities and
requirements of the GT-R, the sequential 6-
speed dual clutch transmission is unlike a
typical automatic transmission. You will likely
hear mechanical sounds from the transmis-
sion, particularly at slow speeds and at idle.
This condition is normal.
CRACKS ON BRAKE PAD
The friction material of the GT-R disc brake pad
is bonded to the pad backing plate more
strongly than conventional brake pads to with-
stand the high brake temperatures. The friction
material and backing plate expand due to heat at
different rates. Some cracks may be on the
surface of the friction material due to the
differences in expansion rates and the strong
bond between the friction material and backing
plate. The cracks do not indicate the brake pads
need to be replaced.
BRAKE DUST
This vehicle is equipped with high performance
brakes, and the characteristics of the brake pad
material may cause more brake dust than other
vehicles. NISSAN recommends a wheel coating
that helps prevent the brake dust from sticking
to the wheels. Contact a GT-R certified NISSAN
dealer for more details.
MECHANICAL LIMITED SLIP DIF-
FERENTIAL (LSD) CHARACTERIS-
TICS
The differential oil has a high viscosity and is
very thick when cold. If the vehicle accelerates
from a stop with the steering wheel turned in
cold temperatures, the inner wheel tire may slip
and some noise or vibration may be heard. This
phenomenon is unique to vehicles equipped
with the Limited Slip Differential (LSD). When
the steering wheel is returned to the straight-
ahead position or the differential oil warms up,
the noise and vibration decrease.
