RSA (Road Sign Assist) The RSA system detects specific road signs using the front camera and/or navigation system (when speed limit information is available) and notifies the driver via displays and buzzers. Warning: For safe use Driving safely is solely the responsibility of the driver. Pay careful attention to the surrounding conditions in order to ensure safe driving. The RSA assists the driver by providing road sign information, but it is not a replacement for the driver’s own vision and awareness. Situations in which the RSA should not be used When it is necessary to disable the system: When it is necessary to disable the system Situations in which the system may not operate properly Situations in which the sensors may not operate properly: Situations in which the sensors and the systems may not operate properly Display function When a traffic sign is detected, the sign will be displayed on the display. Multiple signs can be displayed. Depending on other functions, displayed status may be limited. RSA and other functions (such as the navigation system) may display different sign information. Note: Operating conditions of the display function Signs will be displayed when the following conditions are met: The system has detected a sign Signs will be disappear when the following conditions are met: When the vehicle has traveled a certain distance after passing the sign 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. When a sign is dirty, faded, tilted or bent When there is a reflected light or shadow on a traffic sign 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 there are trees, utility poles, buildings, or signboards behind a traffic sign When it is difficult to recognize a traffic sign by the front camera due to sunlight, reflected light, or the headlights of another vehicle When it is difficult to recognize a traffic sign by the front camera due to bad weather such as heavy rain, snow, fog, sandstorms, blizzards, etc. When a sign is detected by the front camera for a short amount of time (such as when a nearby sign suddenly becomes visible while turning left or right) 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 a traffic sign is located far from the vehicle When an object similar to the system compatible traffic sign is detected (such as signs, electric signs, signboards, buildings, preceding vehicles with stickers, or directory signs with numbers) When a sign for a frontage road is within detection range of the front camera When driving around a roundabout When a traffic sign for other vehicles such as signs for large vehicles 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 there are non-standard or recently introduced signs When the navigation system map data is out of date When the navigation system cannot be used Caution function In the following situations, the RSA system will output a caution to notify the driver. If the vehicle speed exceeds the speed warning threshold of the speed limit sign displayed on the display, the sign display will flash and a buzzer will sound. When the RSA system detects a no-entry sign (do not enter sign) and determines that the vehicle has entered a no-entry area, the no-entry sign (do not enter sign) displayed on the display will flash and a buzzer will sound. Note: Operating conditions of the caution function Speed limit caution function This function will operate when all of the following conditions are met: A speed limit sign is recognized by the system The vehicle speed exceeds the displayed speed limit by a certain amount No entry caution function This function will operate when all of the following conditions are met: Two or more no entry signs are recognized by the system simultaneously The vehicle is passing between no entry signs recognized by the system Types of road signs supported The following types of objects can be displayed.

	Speed limit
	Do Not Enter
	Stop

Changing the RSA settings The settings of the RSA can be changed through customize settings. (Customizable features)
