2021 NISSAN GT-R heating

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 coolant
reservoir cap. Doing so will cause
substandard cooling performance
and overheating.
REMOVING THE COWL TOP COVERRemove the cowl top cover if necessary.
1. Remove the battery cover.
2. Unfasten the 5 clips and remove thecowl top cover
by pulling it up.Do-it-yourself

.To drive forward, move the shift lever
to the
position.
Starting on level ground or an uphill:
1. Check the shift lever position indicator on the meter to confirm that the
driving gear is selected.
2. Release the parking brake.
3. Release the foot brake pedal gradu- ally, then slowly depress the accelera-
tor pedal to start the vehicle in
motion.
(“R mode start function” page 5-33)
NOTE:
. To prevent the clutch from over-
heating when the parking brake is
applied, engine output is limited
when the accelerator pedal is de-
pressed. In particular, the vehicle
may not start smoothly when the
accelerator pedal is depressed with
the parking brake applied on an
uphill grade. To enable smooth
starting, release the parking brake
before moving the vehicle.
. The hill start assist system operates
when the vehicle is accelerating
from a stop on an uphill. (

When driving the vehicle
WARNING
Do not move the shift lever to theposition while driving. Doing so may
result in an accident due to loss of
engine braking. It may also damage
the transmission.
Normal driving:
Drive with the shift lever in the
position.
The appropriate gear will be automati-
cally shifted according to the position of
the accelerator pedal, the driving speed
and driving conditions.

transmission into a lower gear and
maintains this position depending on
the gradient of the hill.
. The system may down shift according
to the accelerator pedal position and
the vehicle speed.

ging gears while driving, switch to theposition and select the appropriate
gear for the driving conditions.

system. Note that while some fuel pumps
label MMT content, not all do, so you may
have to consult your gasoline retailer for
more details.Aftermarket fuel additives
NOTICE
NISSAN does not recommend the use
of any aftermarket fuel additives
(Example: fuel injector cleaner, in-
take valve deposit removers, etc.)
which are sold commercially. Many
of these additives intended for gum,
varnish or deposit removal may con-
tain active solvent or similar ingre-
dients that can be harmful to the fuel
system and engine.Octane rating tipsUsing unleaded gasoline with an octane
rating lower than recommended above
can cause persistent, heavy spark
knock. (Spark knock is a metallic rap-
ping noise.) If severe, this can lead to
engine damage. If you detect a persis-
tent heavy spark knock even when
using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on levelroads, it is recommended you have a
GT-R certified NISSAN dealer correct the
condition. Failure to correct the condi-
tion is misuse of the vehicle, for which
NISSAN is not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This
in turn may cause excessive fuel con-
sumption or damage to the engine. If any
of the above symptoms are encountered,
it is recommended you have your vehicle
checked at a GT-R certified NISSAN dealer
or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is
no cause for concern, because you get
the greatest fuel benefit when there is
light spark knock for a short time under
heavy engine load.
ENGINE OIL AND OIL FILTER RE-
COMMENDATION
Selecting the correct oilIt is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance.
(
“Capacities and recommended
fluids/lubricants” page 10-2)
Mobil 1 (0W-40) (100% synthetic) is the factory fill oil. The VR38 engine with its
plasma-sprayed bores was developed
using this oil. NISSAN cannot ensure
proper engine operation and durability if
other 0W-40 non-equivalent synthetic oil
is used. If Mobil 1 (0W-40) or equivalent is
not available, Mobil 1 (10W-40) (100%
synthetic) or equivalent may be used;
however, some performance loss may
be noticed.
NOTICE
Using an engine oil other than that
specified could adversely affect the
engine. See the 2021 NISSAN GT-R
Warranty Information Booklet for
details and exclusions.Oil additivesNISSAN does not recommend the use of
oil additives. The use of an oil additive is
not necessary when the proper oil type is
used and maintenance intervals are fol-
lowed.
Oil which may contain foreign matter or
has been previously used should not be
used.
