. 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.

, position the two vehicles (
and
) to bring their batteries into
close proximity to each other. Do not
allow the two vehicles to touch.
2. Apply parking brake. Move the shift lever to the
position. Switch off all unnecessary electrical systems (light,
heater, air conditioner, etc.).
3. Remove the battery cover. Cover the battery with a firmly wrung out moist
cloth to reduce explosion hazard.
4. Connect jumper cables in the se- quence as illustrated (

CAUTION
.Always connect positive (+) to
positive (+) and negative (−) to
body ground (as illustrated), not
to the battery.
. Make sure that the jumper cables
do not touch moving parts in the
engine compartment and that
clamps do not contact any other
metal.
5. Start the engine of the booster vehicle
and let it run for a few minutes.

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 (

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

the headlight switch to the
position
for full illumination when driving at night.
If the parking brake is applied before the
engine is started, the daytime running
lights do not illuminate. The daytime
running lights illuminate once the parking
brake is released. The daytime running
lights will remain on until the ignition
switch is pushed to the OFF position or
the headlights turn on.
Turn signal
Move the lever up or down to signal the
turning direction. When the turn is com-
pleted, the turn signals cancel automati-
cally.

BRAKE SYSTEM INFORMATION
Cracks on brake padThe friction material of the GT-R disc
brake pad is bonded to the pad backing
plate more strongly than conventional
brake pads to withstand the high brake
temperatures. The friction material and
backing plate expand due to heat at
different rates. Some cracks may be on
the surface of the friction material due to
the differences in expansion rates and the
strong bond between the friction material
and backing plate. The cracks do not
indicate the brake pads need to be
replaced. However, depending on the
condition of the cracks, the pads may
need to be replaced. It is recommended
you contact a GT-R certified NISSAN deal-
er.
. This is due to the temperature
differential that occurs because the sur-
faces of the disc rotors become hot while
the inside of the rotor is still cold. How-
ever, this poses no problem in terms of
brake performance, and does not indicate
a malfunction. The brakes do not need to

Rattles from brake pads and creaks
during braking
The high performance brake system of
vehicles equipped with the NCCB (NISSAN
Carbon Ceramic Brake) has more clear-
ance between its brake pad and brake
caliper than regular vehicles, and it uses a
large brake pad to ensure stable brakingperformance under a wide range of driv-
ing conditions such as extremely high
temperature areas or low temperature
areas like snow-covered roads. Accord-
ingly, you may hear light rattles from the
brake pad area when driving over a step,
which is not a malfunction. In addition,
you will hear creaks because of the
characteristics of the material for the disc
rotor. These creaks reduce with time and
wear.
Never park your vehicle for a long time
with the brake system wet.
The materials used for the brake disc
rotor and brake pads for specified NCCB
(NISSAN Carbon Ceramic Brake) are dif-
ferent from those used for the standard
brake system in GT-R. The rotor and pads
will be protected from adhesion caused
by rusting. However, never park your
vehicle for a long time with the brake
system wet. This helps maintain the brake
disc rotor and brake pads for a long time
and prevents an influence on the material
composition of the carbon ceramic rotor
and deterioration in the joint of brake disc
rotor’s full floating structure. Especially
during winter, be sure to park your vehicle
with the brake disc rotor and pads dry to
prevent them from being frozen and
damaged in below freezing temperature
conditions. The carbon ceramic brake forGT-R includes air bubbles in the rotor and
pads. Note that leaving them in the wet
condition tends to cause adhesion due to
freezing.
.
A screeching noise may be heard
when the brake pedal is depressed:
— When driving the vehicle for the first
time in the morning,
— After leaving the vehicle parked for extended periods of time, or
— When the vehicle is damp following rain showers or washing the vehi-
cle.
These sounds are normal. The noise is
caused when the brake pads absorb
moisture, and the noise stops after
the brake is applied several times.
. A screeching noise may also be heard
when the brake pedal is depressed:
— When repeatedly applying gentle
braking, especially on a curve at a
low speed, or
— When the brake rotors have circular scores with the brake temperature
high.
. The NCCB (NISSAN Carbon Ceramic
Brake) causes more screeching noise
in cold weather conditions than in
normal weather conditions.

Changing modes
.
The higher shift speeds in the
position may result in shift shock and jerkiness when starting or shifting.
.
The quickest shifting in the R mode with the transmission in the
position is available when the engine speed is high.
However, the transmission may shift more slowly when the engine speed is low.
Mechanical Limited Slip
Differential (LSD) If the vehicle accelerates from a stop with the steering wheel turned half a turn in cold temperatures, the inner wheel tire
may slip and some noise or vibration may be heard. This phenomenon occurs because the viscosity of the differential oil
becomes thicker and the Limited Slip Differential (LSD) operates with increasing load. When the steering wheel is returned
to the straight ahead position or the differential oil warms up, the noise and vibration decrease.
