SOUND HEARD AROUND TITANIUM
MUFFLER (if so equipped)
When stopping the engine (rapid cooling), you
may hear a metal-rubbing sound or unusual
ticking sound because of the differential thermal
expansion between the inner and outer pipes of
the muffler. This is not a malfunction. The sound
will decrease when the temperature lowers.
DRY CARBON FIBER PARTS (if so
equipped)
Roughness or uneven surfaces of dry
carbon fiber parts and fiber twists
The surfaces of the dry carbon fiber parts are
lightly coated like a race car so that you can feel
the proper texture of real carbon, which may feel
rough. This is normal.
The GT-R dual clutch transmission is a newly-
developed system that uses an electronically
controlled multiple-disc wet clutch attached to
the highly efficient manual transmission. This
transmission has two driving modes.
. & A position (Automatic gearshift):
allows automatic shifting of the manual
transmission.
. & M position (Manual gearshift):
allows quick shifting of the manual transmis-
sion.
NOTE:
When starting or driving on a steep uphill
grade, shift to the
& M position and operate
the paddle shifter to shift down to 1st gear
similar to a manual transmission vehicle.
The GT-R dual clutch transmission was devel-
oped specifically to maximize vehicle perfor-
mance and driving enjoyment. The GT-R
transmission components were designed using
different engineering standards than typical
passenger car transmissions. Because of this,
the GT-R has different operating characteristics,
and various rattle noises may be heard during
some driving conditions because of the follow-
ing items:
. Gear clearances
. Ultralight flywheel
. Dry sump lubrication
These noises do not indicate that there is a
malfunction.
