Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actua-
tor 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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.
When accelerating or driving on slippery
surfaces, 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 VDC system is operating,
the “SLIP” indicator in the instrument
panel blinks.
O
When only the Traction Control System
(TCS) portion of the VDC system is op-
erating, the “SLIP” indicator in the in-
strument panel blinks.
O
If the “SLIP” indicator blinks, the road
conditions are slippery. Be sure to ad-
just your speed and driving to these
conditions. Be sure to drive carefully.

HICLE DYNAMIC CONTROL (VDC) OFF
INDICATOR LIGHT” in the “2. Instru-
ments and controls” section.

Indicator light
If a malfunction occurs in the system,
the “SLIP” and “VDC OFF” indicator
lights illuminate in the instrument
panel. As long as these warning lights
are illuminated, the VDC system func-
tion is canceled.
The VDC system uses an Active Brake Lim-
ited Slip (ABLS) function to improve ve-
hicle traction. The ABLS system works
when one of the driving wheels is spin-
ning on a slippery surface. The ABLS sys-
tem brakes the spinning wheel, which
distributes the driving power to the other
drive wheel. If the vehicle is operated
with the VDC system turned off, all VDC
system and TCS functions will be turned
off. The ABLS system and ABS will still
operate with the VDC system off. If the
ABLS system or ABS is activated, the
“SLIP” indicator light will blink and you
may hear a clunk noise and/or feel a pul-
sation in the brake pedal. This is normal
and is not an indication of a malfunction.
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 indi-
cates 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 is
