The Active Yaw Control (AYC) is a system
with a yaw control function, that controls the
left-right driving/braking force using the
brakes.
The yaw control function is a function that
enhances vehicle cornering performance and
vehicle stability with management of vehicle
turning power (yaw moment) by controlling
the drive power difference of the left and
right wheels and the braking force when the
vehicle does not turn in response to steering
input, such as when the steering wheel is
turned quickly or when driving on slippery
road.
The AYC operation status can be displayed
on the information screen in the instrument
cluster.
To display the status, operate the digital
driver display switches to change the infor-
mation screen.
Refer to “Multi information screen (when the
operation mode of the power switch is ON)”
on page 5-9.
The AYC operation status is displayed.
The amount of the yaw moment is displayed
as a bar graph.

When the brake assist system is in use while
driving, you may feel as if the depressed
brake pedal is soft, the pedal moves in small
motions in conjunction with the operation
noise, or the vehicle body and the steering
wheel vibrate. This occurs when the brake
assist system is operating normally and does
not indicate faulty operation. Continue to
depress the brake pedal.
When the anti-lock brake system (ABS)
warning lamp or only active stability control
warning lamp illuminate, the brake assist
system is not functioning.
