What is Adaptive Cruise Control?

Adaptive Cruise Control (ACC) is an intelligent technology developed as an evolution of standard cruise control. It adds the capability to detect the vehicle ahead and automatically adjust your speed to maintain a safe, pre-set following distance. This helps reduce driver fatigue during long-distance trips or in heavy traffic conditions.

How the System Works

The ACC system uses radar sensors (and in some models, a front-facing camera) mounted at the front of the vehicle to monitor traffic in the same lane:

  • When the road is clear: The vehicle maintains the constant speed you have set.
  • When a vehicle ahead is slower: The system automatically decelerates your vehicle to maintain the following distance.
  • When the vehicle ahead speeds up or changes lanes: The system accelerates your vehicle back to your original set speed.

Stop and Go System: An Assistant for City Traffic

In Ford models equipped with the Stop and Go system (such as the new Ford Ranger and Ford Everest), convenience is taken to the next level:

  • The system can decelerate the vehicle to a complete stop following the vehicle ahead.
  • If the vehicle ahead starts moving within a specified timeframe, the system will automatically accelerate to follow it, making stop-and-go city driving much easier.

Basic Usage

You can control the system using the buttons on the steering wheel:

  • On/Off: Press the button to prepare the system for use.
  • Set: Once you reach your desired speed, press the SET button to begin automatic control.
  • Distance: You can adjust the following distance from the vehicle ahead (usually displayed as bars on the screen) to suit your speed and road conditions.
  • Cancel/Resume: Press the CAN button to temporarily cancel the system, or RES to return to the most recently set speed.

Precautions and Limitations

While the ACC system is highly advanced, the driver must remain focused and ready to take control at all times due to certain limitations:

  • Weather Conditions: Heavy rain, thick fog, or mud obstructing the sensors may prevent the system from operating at full efficiency.
  • Road Geometry: Sharp curves or very steep inclines may affect the radar's detection capabilities.
  • Non-detected Objects: In some cases, the system may not respond to stationary objects, bicycles, or pedestrians.

For maximum safety and to understand the specific operations for your vehicle model, please study your Owner’s Manual thoroughly and ensure the front radar sensor area is kept clean.
