Lexus NX: RSA (Road Sign Assist)

The RSA system recognizes specific road signs using the front camera and/or navigation system (when speed limit information is available) to provide information to the driver via the display.

If the system judges that the vehicle is being driven over the speed limit, performing prohibited actions, etc.

in relation to the recognized road signs, it notifies the driver using a notification display and notification buzzer.

WARNING

■Before using the RSA

Do not rely solely upon the RSA system.

RSA is a system which supports the driver by providing information, but it is not a replacement for a driver's own vision and awareness. Drive safely by always paying careful attention to the traffic rules.

Indication on the multi-information display

When the front camera recognizes a sign and/or information of a sign is available from the navigation system, the sign will be displayed on the multi-information display.

Notification function

In the following situations, the RSA system will notify the driver.

Depending on the situation, a notification function may not operate properly.

■Setting procedure

1. Press or of the meter control switches and select

2. Press or of the meter control switches and select Lexus NX. Using the driving support systems, then press 3. Press or of the meter control switches, select the desired setting, and then press

■Automatic turn-off of RSA sign display In the following situations displayed speed limit and do not enter signs will stop being displayed automatically:

In the following situations, stop and yield signs will stop being displayed automatically:

■Conditions in which the function may not operate or detect correctly In the following situations, RSA does not operate normally and may not recognize signs, display the incorrect sign, etc. However, this does not indicate a malfunction.
