2023 Volvo XC40 Mild Hybrid Electronic stability control
Electronic stability control
The driver display shows this symbol when the system is engaged.
Braking from the system may be heard as a pulsing sound, and the car may accelerate more slowly than expected when applying the throttle.
The system consists of the following subfunctions:
- Stability function (Also known as Active Yaw Control)
- Spin control and traction control system
- Engine Drag Control
- Trailer stability assist
- Roll Stability Control
Warning
- The function is supplementary driver support intended to facilitate driving and make it safer – it cannot handle all situations in all traffic, weather and road conditions.
- The driver is advised to read all sections in the Owner’s Manual that relate to this function to learn about factors such as its limitations and what the driver should be aware of before using the system.
- Driver support functions are not a substitute for the driver’s attention and judgement. The driver is always responsible for ensuring the car is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
(Also known as Active Yaw Control)
The function checks the driving and brake force of the wheels individually in order to stabilize the car.
Spin control and traction control system
Spin control is activated at all speeds, and prevents the wheels from slipping against the road surface during acceleration.
Traction control is active at low speeds, and can brake a slipping wheel to increase traction on the wheel on the opposite side.
Engine Drag Control
Engine Drag Control (EDC)(Engine Drag Control) can prevent involuntary wheel lock-up, e.g. when the engine braking on slippery road surfaces. Involuntary wheel locking while driving can, amongst other things, impair the driver’s ability to steer the car.
