 When the RSA system recog-
nizes a no-entry sign and detects
that the vehicle has entered a
no-entry area based on the map

and a buzzer will sound. (For
vehicles with navigation system)
 If it is detected that your vehicle
is overtaking when a no overtak-
ing sign is displayed on the multi-
information display, the dis-
played sign will flash and a steer-

rectly and a warning indication may
not operate properly.
