NISSAN GT-R 2021 Owners Manual

SONAR SYSTEM OFF SWITCHThe sonar system OFF switch on the
lower side of the instrument panel allows
the driver to turn the sonar system on
and off. To turn the sonar system on and
off, the ignition switch must be in the ON
position. The indicator light
on the
switch will turn off when the system is
turned off. If the indicator light flashes it
may indicate a malfunction in the sonar
system.
The sonar system will turn on automati-
cally under the following conditions.
. When the shift lever is placed in the
position. .
When vehicle speed decreases below
approximately 6 MPH (10 km/h).
. When the ignition switch is placed in
the OFF position and turned back to
the ON position again.

WARNING
Using the systemDepress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes.
The ABS will operate to prevent the
wheels from locking up. Steer the vehicle
to avoid obstacles.

The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip
based on vehicle speed (traction con-
trol function).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle
in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the meter flashes so note the following:
.
The road may be slippery or the
system may determine some action
is required to help keep the vehicle on
the steered path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
. The VDC mode can be changed using
the VDC setup switch. (

transmission and suspension setup
switches” page 5-25)

Dynamic Control (VDC) off indicator light”
page 2-33)
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
meter. The VDC system automatically
turns off.
The VDC setup switch is used to turn off
the VDC system. The VDC off indicator
illuminates to indicate the VDC sys-
tem is off.
When the VDC setup switch is used to
turn off the system, the VDC system still
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

operates to prevent one drive wheel from
slipping by transferring power to a non
slipping drive wheel. The VDC warning
light
will not flash. The VDC
system is automatically reset to on when
the ignition switch is placed in the off
position then back to the on position.

The computer has a built-in diagnostic
feature that tests the system each time
you start the engine and move the vehicle
forward or in reverse at a slow speed.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the
brake pedal. This is normal and is not an
indication of a malfunction.
may illuminate.
. If brake related parts such as
brake pads, rotors and calipers
are not standard equipment or
are extremely deteriorated, the
VDC system may not operate
properly and the VDC warning
light
may illuminate.
. If engine control related parts are
not standard equipment or are
extremely deteriorated, the VDC
warning light
may illuminate.
. When driving on extremely in-
clined surfaces such as higher
banked corners, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate. Do not drive on these types of roads.
. When driving on an unstable sur-
face such as a turntable, ferry,
elevator or ramp, the VDC warn-
ing light
may illuminate. This
is not a malfunction. Restart the
engine after driving onto a stable
surface.
. If wheels or tires other than the
those recommended are used,
the VDC system may not operate
properly and the VDC warning
light
may illuminate.
. The VDC system is not a substi-
tute for winter tires or tire chains
on a snow covered road.
NOTE:
. Always make sure the VDC is ON
before driving the vehicle by check-
ing that the VDC OFF indicator lights
on the meter and the VDC set-up
switch are not illuminated.
The GT-R is a high performance
vehicle and the VDC must be on/
activated to provide proper power-
train operation and intended driva-
bility.Starting and driving

wheels will lose even more trac-
tion.
. Allow more stopping distance
under these conditions. Braking
should be started sooner than on
dry pavement.
. Allow greater following distances
on slippery roads.
. Watch for slippery spots (glare
ice). These may appear on an
otherwise clear road in shaded
areas. If a patch of ice is seen
ahead, brake before reaching it.
Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous ex-
haust gases under your vehicle.
Keep snow clear of the exhaust
pipe and from around your vehi-
cle.
NOTE:
When driving on snow, select the SAVE
mode with the setup switch. By select-
ing the SAVE mode, the engine output is
controlled appropriately for snow or slippery road surfaces. This enables
the vehicle to start or accelerate
smoothly.
ENGINE BLOCK HEATER (if so
equipped)Engine block heaters are used to assist
with cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.To use the engine block heater1. Turn the engine off.
2. Plug the engine block heater cord into
a grounded 3-wire, 3-pronged exten-
sion cord.
3. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
4. The engine block heater must be plugged in for at least 2 - 4 hours,
depending on outside temperatures,
to properly warm the engine coolant.
Use an appropriate timer to turn the
engine block heater on.
5. Before starting the engine, unplug and properly store the cord to keep it
away from moving parts.

To close the electronic control valve, push
the exhaust sound control switch to the
ON side.
To open the electronic control valve, push
the exhaust sound control switch to the
OFF side.
NOTE:
Do not disconnect the electronic control
valve connector. If the connector is not
plugged in, the system will detect this
as a malfunction and engine output will
be limited.
