play. ● When the vehicle speed exceeds the speed warning threshold applied to the
speed limit of the sign displayed on the multi-information display, the sign
color becomes inverted.
● If it is detected that your vehicle is overtaking when a no overtaking sign is dis-
played on the multi-information display, the sign flashes.
● On some models: When the RSA system recognizes a no-entry sign and
detects that the vehicle has entered a no-entry area based on the map infor-
mation of the navigation system, the no-entry sign flashes.
Depending on the situation, traffic environment (traffic direction, speed , unit)
may be detected incorrectly and a warning display may not operate properly.
