NOTE:
Do not keep the starter motor en-
gaged for more than 10 seconds. If
the engine does not start right away,
push the ignition switch to the OFF
position and wait 10 seconds before
trying again.
7. After starting your engine, carefully disconnect the negative cable and
then the positive cable (

page 8-5) Do not attempt to start the engine by
pushing.
NOTICE
Your NISSAN cannot be push-started
or tow-started. Attempting to do so
may cause transmission damage.
WARNING
.
Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radia-
tor filler cap and the coolant
reservoir cap while the engine is
still hot. When the cap is removed,
pressurized hot water will spurt
out, possibly causing serious in-
jury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect unusual noise, etc., take the
following steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the
position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the temperature
control to maximum hot and fan

, open the
reservoir cap (pressure type)and add
coolant up to between the MAX
and
MIN
level. If the reservoir is empty, open
the radiator filler cap
and check the
coolant level in the radiator when the
engine is cold. If there is insufficient
coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to between
the MAX
and MIN
level. This vehicle contains Genuine NISSAN
Long Life Antifreeze/Coolant (blue). The
life expectancy of the factory-fill coolant
is 24,000 miles (38,400 km) or 2 years.
Mixing any other type of coolant or the
use of non-distilled water will reduce the
life expectancy of the factory-fill coolant.
Refer to the “9. Maintenance and sche-
dules” section of this manual for more
details.
If the cooling system frequently re-
quires coolant, it is recommended you
have it checked by a GT-R certified
NISSAN dealer.
Check that the level of coolant is between
MAX and MIN on the pressurized radiator
reservoir. If the level is below the mid-
point, the amount of coolant circulating
may be insufficient for maximum vehicle
performance, possibly causing engine
overheating or other trouble.
For the coolant level and mixture ratio
when engaging in performance driving,
see
“Coolant level and mixture ratio”
page GTR-15.
Except for NISMO models:
If it is difficult to determine the midpoint
between MAX and MIN, remove the cool-
ant reservoir cap and look inside through
the opening to check that the coolant
level is above the divider
between the
top half and bottom half of the pressur- ized coolant reservoir.
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.
. If you have added only water as
the coolant in an emergency,
change it to a coolant mixture
ratio specified as soon as possi-
ble.CHANGING ENGINE COOLANTIf major cooling system repairs are re-
quired, it is recommended you contact a
GT-R certified NISSAN dealer. The service
procedures can be found in the appro-
priate NISSAN Service Manual.
Improper servicing can result in re-
duced heater performance and engine
overheating.

.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. (
“Hill
Start Assist System” page 5-39)
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.
Passing:

position. This automatically shifts the
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.
. If the transmission is frequently chan-
ging gears while driving, switch to theposition and select the appropriate
gear for the driving conditions.
Driving on a downhill:
.position and 4th or 3rd gear will
provide gentle engine braking.
When driving on a steep downhill, select-
ing the
position and 2nd or 1st gear will
provide powerful engine braking.

gaged for more than 10 seconds. If

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.

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.
