The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, the VDC system helps to perform the
following functions.

●

Controls brake pressure to reduce wheel slip
on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.

●

Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).

●

Controls brake pressure at individual wheels
and engine output to help the driver main-
tain control of the vehicle in the following
conditions:

– understeer (vehicle tends to not follow

the steered path despite increased steer-
ing input)

– oversteer (vehicle tends to spin due to

certain road or driving conditions).

The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.

When the VDC system operates, the VDC warn-

ing light

in the instrument panel flashes

so note the following:

●

The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.

●

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 properly.

●

Adjust your speed and driving to the road
conditions.

See “Vehicle Dynamic Control (VDC) warning
light” in the “2. Instruments and controls”
section.

If a malfunction occurs in the system, the VDC

warning light

illuminates in the instru-

ment panel. The VDC system automatically
turns off.

The VDC OFF switch is used to turn off the VDC

system. The VDC off indicator

illuminates

to indicate the VDC system is off. When the VDC
switch is used to turn off the system, the VDC
system still operates to prevent one drive wheel
from slipping by transferring power to a non
slipping drive wheel. The VDC warning light

flashes if this occurs. All other VDC

functions are off, except for rise-up and
build-up and brake force distribution, and the

VDC warning light

will not flash. The VDC

system is automatically reset to on when the

ignition switch is placed in the off position then
back to the on position.

See “Vehicle Dynamic Control (VDC) warning
light” in the “2. Instruments and controls”
section and “Vehicle Dynamic Control (VDC) off
indicator light” in the “2. Instruments and con-
trols” section.

The computer has a built-in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or 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 malfunc-
tion.

ACTIVE TRACE CONTROL (if so
equipped)

This system senses driving based on the driv-
er’s steering and acceleration/braking patterns,
and controls brake pressure at individual
wheels and engine output to help smooth ve-
hicle response.

When the drive mode selector switch is set to
the “SPORT” mode, the amount of brake control
provided by active trace control is reduced.
