● When driving on extremely inclined sur-
faces such as higher banked corners,
the Traction Control System may not
operate properly and the
indica-
tor light may come on. Do not drive on
these types of roads.
● If wheels or tires other than the recom-
mended ones are used, the Traction
Control System may not operate prop-
erly and the
indicator light may
come on.
● The Traction Control System is not a
substitute for winter tires or tire chains
on a snow covered road.
The Vehicle Dynamic Control (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.
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,VDC and TCSfunctions will beturned 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
engineand move the vehicle 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.
WARNING
● The Vehicle Dynamic Control system is
designed to help maintain traction with
the road surface but does not prevent
accidents due to abrupt steering opera-
tion at high speeds or by careless or
dangerous driving techniques. Reduce
vehicle speed and be especially careful
when driving and cornering on slippery
surfaces and always drive carefully.
