If your vehicle has this available feature, Adaptive Cruise Control† can automatically maintain a driver-selected gap time from the detected vehicle you’re following while you steer. This feature reduces the need to frequently brake and accelerate when you’re driving.

Why Isn’t Adaptive Cruise Control Working Properly?

Safety Considerations When Using Adaptive Cruise Control

Why Isn’t Adaptive Cruise Control Working Properly?

Adaptive Cruise Control uses a forward-looking camera or a forward-looking camera and radar technology (depending on your vehicle) to monitor vehicles you’re following. If the system doesn’t detect a vehicle ahead, Adaptive Cruise Control works just like cruise control and maintains your selected cruise speed. When the system detects a vehicle ahead of you in your lane, it will automatically slow down or speed up your vehicle to maintain your selected following gap.

 

The Adaptive Cruise Control camera is located behind the windshield in front of the rearview mirror. It’s important to keep the windshield clean for the camera to work properly. On some vehicles, the feature also uses radar sensors located in the front grille or bumper. Keep these areas of the vehicle clean. Read your Owner’s Manual for cleaning instructions.

 

Bad weather that affects road surface traction or visibility may impact its performance. Also, if the forward-looking camera or radar sensors are obstructed in any way, the system will not perform as expected. Adaptive Cruise Control systems may not perform as expected where lighting is poor or when following vehicles with unusual shapes.

 

Some things that can keep your Adaptive Cruise Control from working properly:

 

  • Bad weather that affects road visibility
  • Moisture on the inside or outside of the windshield
  • Blocked or dirty radar sensors or cameras
  • Poor lighting
  • Vehicles being followed that have unusual shapes

Safety Considerations When Using Adaptive Cruise Control

  • The system can only brake so much. Your complete attention is always required while driving
  • Adaptive Cruise Control does not steer your vehicle. You must always be in control of vehicle steering
  • The system may not react to parked, stopped or slow-moving vehicles. You should always be ready to take action and apply the brakes
  • Don’t use the system on winding or hilly roads, on freeway exit or entrance ramps, or when trailering (unless Adaptive Cruise Control with trailering is equipped). In these driving conditions, the system may not detect the vehicle ahead
  • The system can’t detect traffic lights or traffic signs, so you still need to brake when necessary at intersections and lights
