Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Adaptive Dynamic Brake Control (F0x, F1x)
The adaptive dynamic brake control is a function of the ICM control unit or LDM control unit. The adaptive dynamic brake control is only available on vehicles with Active Cruise Control with Stop&Go function.
The adaptive dynamic brake control provides its greatest benefit in emergency braking situations. When the driver of the vehicle ahead brakes sharply, the ACC sensor detects this situation. Dynamic Brake Control assists in braking in a manner that is most effective in preventing a collision.
The following functions are available:
- Pre-filling of the brake system
- Adaptation of a number of parameters for the braking functions in the DSC according to the situation
- visual warning for the driver on the instrument panel or Head-Up Display in event of an advance warning
- visual and acoustic warning for the driver in the event of an acute warning
The adaptive Dynamic Brake Control can be switched on using the corresponding button in the assist system control box. After the warning function as been switched on, the following can be set using the control center:
- Switch pre-warning on/off
- Adjust the time of the pre-warning
This setting has no effect on the time of a warning where the ACC* requests driver intervention or braking.
The adaptive dynamic brake control can also be switched on without activating the ACC Stop&Go function.
