Display Function
• When the front camera detects a sign or information of a sign is available from the navigation system, the sign will be displayed on the display.
• Multiple signs can be displayed.
Depending on the specifications of the vehicle, the number of displayed signs may be limited.
■ Operating conditions of sign display
Signs will be displayed when the following conditions are met:
●The system has detected a sign
In the following situations, a displayed sign may stop being displayed:
●When a new sign has not been detected for a certain distance
●When the system determines that the road being driven on has
changed, such as after a left or right turn
■ Situations in which the display function may not operate properly
In the following situations, the RSA
system may not operate properly and may not detect signs or may display the incorrect sign. However,
this does not indicate a malfunction.
●When a sign is dirty, faded, tilted or bent
●When the contrast of an electronic sign is low
●When all or part of a sign is hidden by a tree, utility pole, etc.
●When a sign is detected by the front camera for a short amount of time
●When the driving state( turning, changing lanes, etc.) is judged incorrectly
●When a sign is immediately after a freeway junction or in an adjacent lane just before merging
●When stickers are attached to the rear of a preceding vehicle
●When a sign similar to a system compatible sign is detected as a system compatible sign
●When a speed limit sign for a frontage road is within detection
range of the front camera
●When driving around a roundabout
●When a sign intended for trucks, etc. is detected
●When a sign has a supplemental
sign( end point, day of week, time of day, etc.)
●When there is a sign within a traffic restricted area, such as a roadworks area
●When the navigation system map data is out of date
●When the navigation system cannot be used
In this case, the speed limit signs displayed on the multi-information display and navigation system display may differ.
