is low

camera (DSBS II) for a short amount of
time

ing lanes, etc.) is judged incorrectly

Notification function
In the following situations, the traffic sign
recognition system will output a warning to
notify the driver.
• If the vehicle speed exceeds the speed
warning threshold of the speed limit sign
displayed on the information display, the
sign display will be emphasized and a
buzzer will sound.
Also when the limit speed to be displayed
is changed due to the change of driving
zones, etc., the sign display will be empha-
sized and a buzzer will sound* to alert the
driver. *
*: The availability of emphasized display
and buzzer depends on the country where
the vehicle is available.
