The 2011 BMW 335i Coupe has five systems that help maintain vehicle stability in adverse driving conditions.
|Antilock Brake System
|Prevents locking of the wheels during braking.
|Electronic Brake-Force Distribution
|Controls brake pressure in rear wheels to ensure stable braking behavior.
|Dynamic Brake Control
|Applies maximum brake force boost when braking rapidly (the maximum application of ABS).
|Dynamic Stability Control
|Prevents drive wheels from losing traction when accelerating.
|Dynamic Traction Control
|A version of DSC in which the drive output is optimized for particular road conditions. Provides maximum drive output, but with reduced driving stability.

Dynamic Stability Control (DSC): OFF
- Press and hold DTC button for at least 3 seconds.
- DSC indicator lamp lights up.
- Both DSC and DTC have been deactivated.
- Driver has full control.
- Engine power will not be reduced and stabilizing actions are no longer executed.
- To reactivate DSC, press DTC button again.
Dynamic Traction Control (DTC): ON
- Briefly press DTC button.

Officially, BMW state that DTC is for low traction situations such as snow, mud, gravel or ice. However, it’s pretty clear that it’s also designed to allow for a more sporting drive. Motoring journalists often describe it as emulating an electronic limited-slip differential.
