● Tire type and condition of tires may also
affect braking effectiveness.
● When replacing tires, install the speci-
fied size of tires on all four wheels.
● When installing a spare tire, make sure
it is the proper size and type as speci-
fied on the Tire and Loading Informa-
tion label. For tire placard location in-
formation, refer to “Tire and Loading
Information label” in the “Technical and
consumer information” section of this
manual.
● Refer to “Wheels and tires” in the
“Maintenance and do-it-yourself” sec-
tion of this manual.
When accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the Vehicle
Dynamic Control (VDC) system, sensors detect
these movements and control the braking and
engine output to help improve vehicle stability.
● When the vehicle dynamic control (VDC)
system is operating, the slip indicator in the
instrument panel blinks.
● When only the traction control system (TCS)
portion of the vehicle dynamic control sys-
tem is operating, the slip indicator will also
blink.
● If the slip indicator blinks, the road condi-
tions are slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle dynamic
control off indicator light” in the “Instruments
and controls” section.
● Indicator light
If malfunction occurs in the system,
the
and indicator lights come
on in the instrument panel.
As long as these warning lights are on, the
traction control function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) system 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 vehicle
dynamic control system off using the VDC OFF
switch, all VDC and ABLS functions will be
turned off. The ABS will still operate with the VDC
system off. If the ABLS system is activated, the
slip indicator light will blink and you may hear a
clunk noise and/or feel a pulsation in the brake
pedal. This is normal.
While 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 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 malfunction.
