pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates 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 an INFINITI dealer.
The Vehicle DynamicControl (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving situations, the
system will control braking and engine output to
help keep the vehicle on its steered path.
When the Vehicle Dynamic Control (VDC)
system is operating, the slip indicator in the
instrument panel blinks.
If the slip indicator blinks, the road condi-
tions may be slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle Dynamic
Control (VDC) off indicator light” in the “In-
struments and controls”section.
Indicator light
If a malfunction occurs in the system, the
SLIP and
indicator lights come on
in the instrument panel.
If the 4WD transfer case is shifted into
4LO the
indicator light will come
on and the VDC system will be turned off.
See “Transfer case shifting procedures”
earlier in this section.
As long as these indicator lights are on,
the traction control function is canceled.
If the vehicle is operated with the Vehicle Dy-
namic Control system off using the VDC OFF
switch, most VDC and Traction Control System
(TCS) functions will be turned off. The SLIP
indicator will flash if wheel spin is detected. The
ABS will still operate with the VDC system off.
When the VDC system is operating, 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 prop-
erly.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine andmove thevehicle forwardor 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.
