the ABS warning light on the instrument panel.
The brake system then operates normally, but
without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a GT-R certified NISSAN dealer.Normal operationThe ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h) . The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.
The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving situa-
tions, the system will control braking and engine
output to help keep the vehicle on its steered
path.
.The VDC mode can be changed using the
VDC setup switch. (
“VDC, TRANS-
MISSION AND SUSPENSION SETUP
SWITCHES” page 5-21)
. When the VDC system is operating, the
indicator in the instrument panel blinks.
. If the
indicator blinks, the road condi-
tions may be slippery. Be sure to adjust your
speed and driving to these conditions. Be
sure to drive carefully. (

light” page 2-29) (

Control (VDC) off indicator light” page 2-
29)
. Indicator light
If a malfunction occurs in the system, the
and
indicator lights illuminate in
the instrument panel. As long as these
indicators are illuminated, the VDC system
function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) function to improve vehicle traction.
The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The ABLS system brakes the spinning wheel, which
distributes the driving power to the other drive
wheel. If the vehicle is operated with the VDC
setup switch pushed and the VDC system
turned off, all VDC systems will be turned off.
The ABLS system and ABS will still operate with
the VDC system off.
While the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise
or feel a vibration from under the hood. This is
normal and indicates that the VDC system is
working properly.
The VDC system computer has a built-in
diagnostic feature that tests the system each
time you start the engine and move the vehicle at
a low speed forward or backward. When the
self-test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal. This
does not indicate that there is a malfunction.
WARNING
.
The VDC system is designed to help
improve driving stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
due to careless or dangerous driv-
ing techniques. Reduce vehicle
speed and be especially careful
when driving and cornering on slip-
pery surfaces and always drive care-

fully.
. If engine related parts such as
muffler are not standard equipment
or are extremely deteriorated, the
indicator or
indicator or
both indicator lights may illuminate.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars and bushings are
not NISSAN approved or are extre-
mely deteriorated the VDC system
may not operate properly. This could
adversely affect vehicle handling
performance, and the
indicator
or
indicator or both indicator
lights may illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the
indicator
or
indicator or both indicator
lights may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the
in-
dicator or
indicator or both indicator lights may illuminate. Do
not drive on these types of roads.
. When driving on unstable surfaces
such as a turntable, ferry, elevator
or ramp, the
indicator or
indicator or both indicator lights
may illuminate. This does not indi-
cate that there is a malfunction.
Restart the engine after driving onto
a stable surface.
. If wheels or tires other than those
recommended are used, the VDC
system may not operate properly
and the
indicator or
in-
dicator or both indicator lights may
illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
NOTE:.Make sure VDC is on before driving the
vehicle. The VDC OFF mode is an
emergency mode to help free a vehicle
stuck in mud or snow by temporarily
stopping VDC operation and keeping
torque on the wheels.
. When attempting to free the vehicle
from mud or fresh snow, the VDC will detect the tire slipping, and the engine
speed may not increase even when the
accelerator pedal is depressed. To raise
the engine speed, use the VDC set up
switch to turn the VDC system OFF.
. When the VDC system is turned OFF,
all VDC functions (including traction
control) , except for the ABS functions,
are deactivated.
