Circuit/System Description

The lane departure warning is enabled and disabled through the lane departure warning switch. When enabled, the frontview camera module will illuminate the indicator located in the switch. For the exact location of the lane departure warning switch, refer to the Owner's Manual.

For vehicles without UGN, the indicator and switch are connected to the frontview camera module and the system operates as a stand-alone feature.
