versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is no rmally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if the driver normally operates the vehicle in a region
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration

*: If equipped
The RSA system recognizes spe-
cific road signs using the front cam-
era and/or navigation system (when
speed limit information is available)
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 actions, etc.,
according to the recognized road
signs, it notifies the driver through a
visual notification and notification
buzzer.
When the front camera recognizes
a sign and/or information of a sign
is available from the navigation sys-
tem, the sign will be displayed on
the multi-information display.
 When the driving support system
information is selected, a maxi-
mum of 3 signs can be dis-
played. ( P. 8 4 )
 When a tab other than the driving
support system information is
selected, the following types of
road signs will be displayed.
