White light means the adaptive cruise control system is turned on. The light will no longer be lit once you’ve turned off the speed control system.
Green light means the adaptive cruise control system is actively in use, and you may feel the vehicle slow down automatically when traffic is ahead.
No light means adaptive cruise control is no longer active.
Note: Braking at any time turns cruise control features off, and you’ll regain manual control of your vehicle’s speed without any delay.
Learn how to set and turn off adaptive cruise control in your vehicle’s Owner Manuals.
