RSA (Road Sign Assist)RSA (Road Sign Assist)**If equippedThe RSA system detects specific road signs using the front camera and/or navigation
system (if equipped) (when speed limit information is available) and warns the driver
via displays and buzzers.Warning:For safe useDriving safely is solely the responsibility of the driver. Pay careful attention to
the surrounding conditions in order to ensure safe driving.Do not rely solely upon the RSA. The RSA assists the driver by providing road sign
information, but it is not a replacement for the driver’s own vision and awareness.
Driving safely is solely the responsibility of the driver. Pay careful attention to
the surrounding conditions in order to ensure safe driving.Situations in which the RSA should not be usedWhen it is necessary to disable the system: When it is necessary to disable the systemSituations in which the system may not operate properlySituations in which the sensors may not operate properly: Situations in which the sensors and the systems may not operate properlyDisplay FunctionWhen the front camera detects a sign or information of a sign is available from the
navigation system (if equipped), 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.Note:Operating conditions of sign displaySigns will be displayed when the following conditions are met:The system has detected a signIn the following situations, a displayed sign may stop being displayed:When a new sign has not been detected for a certain distanceWhen the system determines that the road being driven on has changed, such as after
a left or right turnSituations in which the display function may not operate properlyIn 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 bentWhen the contrast of an electronic sign is lowWhen 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 timeWhen the driving state (turning, changing lanes, etc.) is judged incorrectlyWhen a sign is immediately after a freeway junction or in an adjacent lane just before
mergingWhen stickers are attached to the rear of a preceding vehicleWhen a sign similar to a system compatible sign is detected as a system compatible
signWhen a speed limit sign for a frontage road is within detection range of the front
cameraWhen driving around a roundaboutWhen a sign intended for trucks, etc. is detectedVehicles with navigation system: When the navigation system map data is out of dateVehicles with navigation system: When the navigation system cannot be usedIn this case, the speed limit signs displayed on the multi-information display and
navigation system display may differ.Notification functionIn the following situations, the RSA 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 display, the sign display will be emphasized and a buzzer will sound.When the RSA system detects a do not enter sign and determines that the vehicle has
entered a no-entry area, the do not enter sign displayed on the display will flash
and a buzzer will sound.Note:Operating conditions of the notification functionsExcess speed notification functionThis function will operate when the following condition is met:A speed limit road sign is recognized by the system.No entry notification functionThis function will operate when all of the following conditions are met:More than one no entry road signs are recognized by the system simultaneously.The vehicle is passing between no entry road signs recognized by the system.Types of road signs supportedThe following types of road signs can be displayed.However, non-standard or recently introduced traffic signs may not be displayed.

Depending on the specifications of the vehicle, signs may be displayed overlapping.Changing RSA settingsThe following settings of the RSA can be changed through customize settings. (Customizable features)
