Active stability control (ASC)

The active stability control (ASC) takes overall control of the
anti-lock braking system, traction control function and skid
control function to help maintain the vehicle’s control. Also
refer to the following pages on the anti-lock braking system,
traction control function and skid control function.
Anti-lock braking system (ABS) → P.3- 4 1
Traction control function → P. 3 - 4 6

● 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 malfunction.
• When the electric motor switch is set to the “ON” posi-
tion.
• 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 whining 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 illu-
minated, the ASC is not active.
Traction control function
N00559200050
On slippery surfaces, the traction control function prevents the
drive wheels from spinning excessively, thus helping the vehi-
cle to start moving from a stopped condition. It also provides
sufficient driving force and steering performance as the vehicle
turns while pressing the acceleration pedal.
CAUTION
!
● Do not over-rely on the ASC. Even the ASC cannot
prevent the natural laws of physics from acting on
the vehicle. This system, like any other system, has
limits and cannot help you to maintain traction and
control of the vehicle in all circumstances. Reckless
driving can lead to accidents. It is the driver’s
responsibility to drive carefully. This means taking
into account the traffic, road and environmental
conditions.
● Be sure to use the specified type and size of tire on
all four wheels. Otherwise, the ASC may not work
properly.
● Do not install any aftermarket limited slip differen-
tial (LSD) on your vehicle. The ASC may stop func-
tioning properly.
CAUTION
!
● When driving a vehicle on a snowy or icy road, be
sure to install snow tires and drive the vehicle at
moderate speeds.
