air NISSAN GT-R 2021 Service Manual

.If the vehicle becomes involved in
a collision but the pretensioner is
not activated, it is recommended
to have the pretensioner system
checked and, if necessary, re-
placed by a GT-R certified NISSAN
dealer.
. No unauthorized changes should
be made to any components or
wiring of the pretensioners. This
is to prevent damage to or acci-
dental activation of the preten-
sioners. Tampering with the
pretensioner system may result
in serious personal injury.
. Work around and on the preten-
sioners should be done by a GT-R
certified NISSAN dealer. Installa-
tion of electrical equipment
should also be done by a GT-R
certified NISSAN dealer. Un-
authorized electrical test equip-
ment and probing devices should
not be used on the pretensioners.
. If you need to dispose of a pre-
tensioner or scrap the vehicle, it is
recommended you contact a
GT-R certified NISSAN dealer. In-
correct disposal procedures
could cause personal injury. The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with
the seat belt retractor, it helps tighten the
seat belt when the vehicle becomes
involved in certain types of collisions,
helping to restrain front seat occupants.
The pretensioner is encased with the seat
belt retractor. These seat belts are used
the same way as conventional seat belts.
When a pretensioner activates, smoke is
released and a loud noise may be heard.
The smoke is not harmful, and it does not
indicate a fire. Care should be taken not
to inhale it as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air
promptly.
After pretensioner activation, load limiters
allow the seat belt to release webbing (if
necessary) to reduce forces against the
chest.
The supplemental air bag warning light
“Supplemental air bag warning light”
page 1-48 for more details.) If the opera-
tion of the supplemental air bag warning
light indicates there is a malfunction, it is
recommended you have the system
checked by a GT-R certified NISSAN deal-
er. When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s Man-
ual.

SUPPLEMENTAL AIR BAG WARNING
LIGHTThe supplemental air bag warning light,
displaying
in the meter, monitors the
circuits for the air bag systems, preten-
sioners and all related wirings.
When the ignition switch is in the ON
position, the supplemental air bag warn-
ing light illuminates for about 7 seconds
and then turns off. This means the SRS air
bag systems are operational.
If any of the following conditions occur,
the air bag and/or pretensioner systems
need servicing:

.The supplemental air bag warning
light remains on after approximately
7 seconds.
. The supplemental air bag warning
light flashes intermittently.
. The supplemental air bag warning
light does not come on at all.
Under these conditions, the air bag and/
or pretensioner systems may not operate
properly. They must be checked and
repaired. It is recommended you take
your vehicle to the nearest GT-R certified
NISSAN dealer.

engine in the red zone may cause
serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGEThe gauge indicates the engine coolant
temperature.
The engine coolant temperature is within
the normal range when the gauge needle
points within the zone
shown in the
illustration.
The engine coolant temperature varies
with the outside air temperature and
driving conditions.

Brake warning light
This light functions for both the parking
brake and the foot brake systems.
WARNING LIGHTS, INDICATOR
LIGHTS AND AUDIBLE REMINDERS

Parking brake indicator:
When the ignition switch is in the ON
position, the light comes on when the
parking brake is applied.
Low brake fluid warning light:
When the ignition switch is in the ON
position, the light warns of a low brake
fluid level. If the light comes on while the
engine is running with the parking brake
not applied, stop the vehicle and perform
the following:
1. Check the brake fluid level. Add brakefluid as necessary. (
“Brake fluid”
page 8-11)
2. If the brake fluid level is correct, it is recommended you have the warning
system checked by a GT-R certified
NISSAN dealer.
Anti-lock Braking System (ABS) warning
indicator:
When the parking brake is released and
the brake fluid level is sufficient, if both
the brake warning light and the Anti-lock
Braking System (ABS) warning light illu-
minate, it may indicate the ABS is not
functioning properly. It is recommended
you have the brake system checked, and
if necessary repaired, by a GT-R certified
NISSAN dealer promptly. (
“Anti-lock
Braking System (ABS) warning light” page 2-29)
Brake pad wear warning indicator
(models with NCCB (NISSAN Carbon
Ceramic Brake) package):
When the brake warning light illuminates,
it may indicate that there is brake pad
wear. Have the brake system checked
and brake pads replaced as soon as
possible. It is recommended you contact
a GT-R certified NISSAN dealer for this
service.
WARNING
.
Your brake system may not be
working properly if the warning
light is on. Driving could be dan-
gerous. If you judge it to be safe,
drive carefully to the nearest
service station for repairs. Other-
wise, have your vehicle towed because driving it could be dan-
gerous.
. Pressing the brake pedal with the
engine stopped and/or low brake
fluid level may increase your
stopping distance and braking
will require greater pedal effort
as well as pedal travel.
. If the brake fluid level is below the
minimum or MIN mark on the
brake fluid reservoir, do not drive
until the brake system has been
checked. It is recommended you
contact a GT-R certified NISSAN
dealer.
Charge warning light
If the light comes on while the engine is
running, it may indicate the charging
system is not functioning properly. Turn
the engine off and check the alternator
belt. If the belt is loose, broken, missing or
if the light remains on, it is recommended
you see a GT-R certified NISSAN dealer
immediately.

warning light comes on when the
ignition switch is pushed to ON. It turns
off soon after the engine is started.
If the AWD system malfunctions, the
warning light will either remain illumi-
nated or blink. (
“All-Wheel Drive
(AWD)” page 5-42)
“Tire and loading infor-
mation label” page 10-14)
If the tire pressure is insuffi-
cient, fill with nitrogen gas. It
is recommended you contact
a GT-R certified NISSAN dealer
about filling with nitrogen
gas. If nitrogen gas is not
available, compressed air
may be safely used under
normal driving conditions. However, NISSAN recom-
mends refilling with nitrogen
gas for maximum tire perfor-
mance.
. If the warning light is still on after
the above operations, have your
vehicle checked as soon as pos-
sible. It is recommended you have
the vehicle checked by a GT-R
certified NISSAN dealer.
or
Anti-lock Braking
System (ABS) warning light
When the ignition switch is in the ON
position, the Anti-lock Braking System
(ABS) warning light illuminates and then
turns off. This indicates the ABS is opera-
tional.
If the ABS warning light illuminates while
the engine is running, or while driving, it
may indicate the ABS is not functioning
properly. It is recommended you have the
system checked by a GT-R certified
NISSAN dealer.
If an ABS malfunction occurs, the anti-
lock function is turned off. The brake
system then operates normally, but with-
out anti-lock assistance. (
