Safety

Why does my vehicle slow down sometimes while I'm using cruise control?

If your vehicle is equipped with adaptive cruise control, and if it is enabled, you may feel the vehicle slow down automatically when traffic is ahead.  
Cruise control

Once you turn on the adaptive cruise control feature, it can help you maintain your cruising speed without keeping your foot on the pedal, as well as stay a predetermined gap from the car in front of you. The system uses radar to scan for traffic ahead, and automatically adjusts your speed to maintain that preselected gap. 

The feature’s indicator lights change color to display the system mode.10

  • 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  • No light means adaptive cruise control is no longer active.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.
