When is the ATC active?

The ATC, or Automatic Traction Control, is designed to assist in maintaining traction during driving conditions where traction loss might occur, such as on wet or slippery surfaces. The correct answer indicates that the ATC is active when the ATC lamp is blinking continuously.

This blinking light signifies that the ATC system is actively working to prevent wheel spin by adjusting brake pressure or engine power. It serves as a warning to the driver that the system is engaging, which is crucial for maintaining control of the vehicle. A constant blinking light means the system is functioning to enhance vehicle stability and safety.

In contrast, while the vehicle is in motion, the ATC may or may not be actively engaged depending on the driving conditions, making that option less definitive. When the engine is turned off, the ATC cannot function, and when the brakes are released, the system may not necessarily be active unless specific slippery conditions are encountered. Hence, the blinking indicator is the most definitive sign of the ATC being engaged.
