This symbol will be displayed in the instrument panel when the system is intervening.

When the system has intervened to apply the brakes, a pulsing sound may be heard and the vehicle may accelerate more slowly than expected when the accelerator pedal is depressed.

The system consists of the following sub-functions:
  • Stability control2
  • Spin control and active yaw control
  • Engine drag control
  • Trailer Stability Assist

 Warning

  • The function is supplementary driver support intended to facilitate driving and help 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 about this function to learn of its limitations, which the driver must be aware of before using the function.
  • Driver support functions are not a substitute for the driver's attention and judgment. The driver is always responsible for ensuring the vehicle 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.

Stability control2

This function helps control the driving and braking force of each individual wheel in an attempt to stabilize the vehicle.

Spin control and active yaw control

Spin control is active at all speeds and prevents the wheels from spinning while the vehicle is accelerating.

Active yaw control is active at low speeds and can brake the wheels that are spinning in order to increase power to the wheel on the opposite side.

Engine drag control

Engine drag control (EDC3) can help prevent involuntary wheel locking, such as after engine braking on slippery roads. Inadvertent wheel lock while driving could impair the driver's ability to steer the vehicle.

Trailer Stability Assist*4

Trailer Stability Assist (TSA5) is designed to help stabilize a vehicle that is towing a trailer if the vehicle and trailer have begun to sway.
