Normal operation

The ABS operates at speeds above 5 to 10 km/h (3
to 6 MPH). The speed varies according to road
conditions.
When the ABS senses that one or more wheels are
close to locking up, the actuator 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 bonnet or feel a vibration
from the actuator when it is operating. This is
normal and indicates that the ABS is operating
properly. However, the pulsation may indicate that
road conditions are hazardous and extra care is
required while driving.

Except for Europe: Vehicle Dynamic Control
(VDC) system
For Europe: Electronic Stability Programme
(ESP) system
The Vehicle Dynamic Control (VDC)/Electronic
Stability Programme (ESP) system uses various
sensors to monitor driver inputs and vehicle
motion. Under certain driving conditions, the
VDC/ESP 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 maintain
control of the vehicle in the following condi-
tions:
— understeer (vehicle tends to not follow the
steered path despite increased steering
input)
— oversteer (vehicle tends to spin due to
certain road or driving conditions).
The VDC/ESP 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/ESP system operates, the slip
indicator 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
bonnet. This is normal and indicates that the
VDC/ESP system is working properly.
* Adjust your speed and driving to the road
conditions.
If a malfunction occurs in the system, the slip
indicator light
illuminates in the instrument
panel. The VDC/ESP system automatically turns
off.
The vehicle information display is used to turn off
the VDC/ESP system. The VDC/ESP off indicator
illuminates to indicate the VDC/ESP system is
off. When the VDC/ESP system is turned off, the
VDC/ESP system still operates to prevent one drive
wheel from slipping by transferring power to a non
slipping drive wheel. The slip indicator light
flashes if this occurs. All other VDC/ESP functions
are off, and the slip indicator light
will not
flash. The VDC/ESP system is automatically reset
to on when the ignition switch is placed in the off
position then back to the on position.
See “Slip indicator light” (P.80) and “Vehicle Dy-
namic Control (VDC) off indicator light (except for
Europe)/Electronic Stability Programme (ESP) off
indicator light (for Europe)” (P.80).
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
