On slippery surfaces, the traction control
function prevents the drive wheels from spin-
ning excessively, thus helping the vehicle to
start moving from a stopped condition. It also
provides sufficient driving force and steering
performance as the vehicle turns while press-
ing the acceleration pedal.

The skid control function is designed to help
the driver maintain control of the vehicle on
slippery roads or during rapid steering
maneuvers. It works by controlling the elec-
tric motor unit output and the brake on each
wheel.

The ASC is automatically activated when the
electric motor switch is turned to the “ON”
position. You can deactivate the system by
pressing down the ASC OFF switch for 3 sec-
onds or longer.
When the ASC is deactivated, the indica-
tor will be illuminated. To reactivate the
ASC, momentarily press the ASC OFF
switch; the indicator is turned off.
NOTE
 An operation noise may be emitted from
under the hood in the following situations.
The sound is associated with checking the
operations of the ASC. At this time, you may
feel a shock from the brake pedal if you
depress it. These do not indicate a malfunc-
tion.
• When the electric motor switch is set to the
“ON” position.
• When the vehicle is driven for a while after
the electric motor unit is turned on.
 When the ASC is activated, you may feel a
vibration in the vehicle body or hear a whin-
ing sound from under the hood.
This indicates that the system is operating
normally. It does not indicate a malfunction.
 When the anti-lock braking system warning
light is illuminated, the ASC is not active.
Traction control function
CAUTION
 When driving a vehicle on a snowy or icy
road, be sure to install snow tires and drive
the vehicle at moderate speeds.
Skid control function
NOTE
 The skid control function operates at speeds
of about 9 mph (15 km/h) or higher.
ASC OFF switch
CAUTION
 For safety reasons, the ASC OFF switch
should be operated when your vehicle is
stopped.
 Be sure to keep the ASC on while driving in
normal circumstances.
NOTE
 Using the ASC OFF switch turns off both the
skid control function and the traction control
function.
 When moving out of mud, sand or fresh
snow, pressing the accelerator pedal may not
allow the electric motor speed to increase. In
such situations, temporarily deactivate the
ASC, using the ASC OFF switch.
