the function is te mporarily canceled.
This warning also operates in the same
way when the driver continuously oper -
ates the steering w heel only a small
amount.
The buzzer also sounds even if the alert
type is set to “Steering wheel vibration”.
●When the system det ermines that the
vehicle may not t urn and instead
depart from its lane while driving around a curve
Depending on the vehicle condition and road conditions, the warning may not
operate. Also, if t he system determines
that the vehicle is driving around a curve, warnings will occur earlier than
during straight-lane driving.
●When the system det ermines that the
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 driver is warned.
Each time the buzze r sounds, the con-
tinuing time of the buzzer becomes lon -
ger.
The buzzer also sounds even if the alert
type is set to “Steering wheel vibration”.
■Vehicle sway wa rning function

*: If equipped
RSA (Road Sign Assist)*
The RSA system recognizes
specific road signs using the
front camera and/or naviga -
tion system (when speed limit
information is available) to pro -
vide information to the driver
via the display.
If the system judges that the
vehicle is being driven over the
speed limit, performing prohib -
ited actions, etc. according to
the recognized road signs, it
notifies the driver through a
visual notification and notifica -
tion buzzer or steering wheel
vibration.
WARNING
■Before using the RSA
Do not rely solely upon the RSA sys- tem. 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.
