●When the system determines that t he driver is driving without holding the
steering wheel while the system is operating
If the driver continues to keep their hands off of the steering wheel, the
buzzer sounds, the driver is warned and the function is temporarily can-
celed. This warning also operates in the same way when the driv er continu-
ously operates the steering wheel only a small amount.
● When the system determines that the vehicle may deviate from th e lane
while driving around a curve while the lane centering function is operating
Depending on the vehicle condition and road conditions, the war ning may
not operate. Also, if the system determines that the vehicle is driving
around a curve, warnings will occur earlier than during straight-lane driving.
● When the system determines that t he driver is driving without holding the
steering wheel while the steering wheel assist of the steering assist function
is operating.
If the driver continues to keep their hands off of the steering wheel and the
steering wheel assist is operating, the buzzer sounds and the d river is
warned. Each time the buzzer sounds, the continuing time of the buzzer
becomes longer.
■ Vehicle sway warning function In the following situations, a warning mes-
sage urging the driver to hold the steering
wheel and the symbol shown in the illus-

RSA (Road Sign Assist)
The RSA system recognizes spe-
cific road signs using the front
camera to provide information to
the driver via the display.
If the system judges that the vehicle is being driven over the speed
limit, performing prohibited ac tions, etc. according to the recognized
road signs, it notifies the driver through a visual notification and notifi-
cation buzzer.
: If equipped
Summary of function
WARNING
■ Before using the RSA
Do not rely solely upon the RSA system. RSA is a system which supports
the driver by providing information, but it is not a replacement for a driver’s
own vision and awareness. Drive safely by always paying careful attention
to the traffic rules.
