(“Intelligent Key battery replace-
ment” page 8-27) .
Make sure the area around the vehicle is
clear.
. Check fluid levels such as en�fine oil, cool-
ant, brake fluid and �bindo�b �basher fluid as
frequently as possible, or at least �bhenever
you refuel.
. Check that all �bindo�bs and li�fhts are clean.
. Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
. Lock all doors.
. Position seat.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen�fers to
do like�bise.
. Check the operation of �barnin�f li�fhts �bhen
the i�fnition s�bitch is pushed to the ON
position. (
“Warnin�f/indicator li�fhts
and audible reminders” pa�fe 2-25) NOTE:
.
This vehicle includes spark plugs that
are designed for maximum perfor-
mance. If the start time becomes long-
er, the plugs may be fouled, making the
engine difficult to start. If this occurs,
start the engine using the procedure
described in this section.
. A click sound may be heard when the
brake pedal is depressed and released.
This is normal.
. A low rattling operating sound may
occur when the engine is started or
stopped. This is because of the trans-
mission gear design, light flywheel and
dry sump lubrication system used in
this transmission. This does not indi-
cate that there is a malfunction. This
sound is likely to occur in particular if
the engine is stopped when the tem-
perature of the transmission oil is high.

BEFORE STARTING THE ENGINE STARTING THE ENGINE

See your 2015 Warranty Information Boo�flet for
important related information and �barranty
coverage exclusions. See also section 2
(
“Transmission �barning light” page 2-30)
and section 5 (“Vehicle Dynamic Control
(VDC) system” page 5-50) of this O�bner’s
Manual, “Transmission Clutch Temperature
High” and “Vehicle Dynamic Control (VDC)
System” for important additional related informa-
tion. The turbocharger system uses engine oil for
lubrication and cooling of its rotating compo-
nents. The turbocharger turbine turns at extre-
mely high speeds and it can get very hot. It is
essential to maintain a supply of oil flo�bing
through the turbocharger system. Therefore, a
sudden interruption of oil supply may cause a
malfunction in the turbocharger.
To ensure prolonged life and performance of the
turbocharger, it is essential to perform the
follo�bing maintenance procedure:
.
Change your engine oil according to the
recommended intervals sho�bn in the sepa-
rate Service and Maintenance Guide. Use
only the recommended engine oil.
. If the engine had been operating at high
engine speed for an extended period of time,
let it idle for a fe�b minutes prior to shut-
do�bn.
. Do not accelerate your engine to high
engine speed immediately after start.
NOTICE
.This vehicle includes spark plugs
that are designed for high perfor-
mance. For this reason, if the engine
is repeatedly started and stopped over a short time, the spark plugs
may become fouled, making the
engine difficult to start. To prevent
diminished starting performance,
avoid starting and stopping the
engine repeatedly during a short
period of time.
NOTE:
. When the vehicle is delivered, the
engine oil level is 0.39 in (10 mm)
below the H mark on the engine oil
dipstick for optimum high performance
driving. The engine oil can be filled up
to the H mark if not engaging in
performance driving.
. Because of the high performance char-
acteristics of the GT-R engine, more
frequent oil level inspections are ne-
cessary. Check the oil level every 1,800
miles (3,000km) and adjust as neces-
sary. Also, change the engine oil based
on the driving conditions. For the
information regarding oil replacement
intervals, refer to the 2015 NISSAN
GT-R Service and Maintenance Guide.

the belt is in poor condition or loose, ha\fe it
replaced or adjusted by a \bT-R certified
NISSAN dealer.
2. Ha\fe the belts checked regularly for condi- tion and tension in accordance with the
maintenance schedule in your NISSAN
Ser\fice and Maintenance \buide.
WARNING
Be sure the engine and the ignition
switch are off and that the parking
brake is engaged securely.
NOTICE
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
REPLACING SPARK PLUGS
If replacement is required, see a \bT-R certified
NISSAN dealer for ser\ficing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-tipped
spark plugs as frequently as the con\fentional
type spark plugs since they will last much longer.
Follow the maintenance schedule in NISSAN
Ser\fice and Maintenance \buide, but do not
reuse them by cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.
