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 operation

The 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 5-22)

. 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. (

. 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-
