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.
Dynamic Traction Control
Dynamic traction control (DTC) offers better traction as a trade off against a reduction in stability in some circumstances. Consequently, its use should be reserved for exceptional conditions (driving in deep snow, for example).
The DTC function approximates to that of DSC with a slightly modified control strategy. DTC can be activated by deactivating DSC (DSC button). DTC intervenes in the braking actions to imitate the function of a conventional differential lock.
Advantage: Higher traction is available with DTC.
Vehicle stabilization intervention (e.g. reduced power output) is made slightly later than with DSC.
This enhances traction with a slight loss of driving stability. Occasionally, a compromise is needed between driving stability and traction.
This is especially true when accelerating and driving uphill on loose surfaces or in deep snow (= friction values demanding increased slip).
DTC allows DSC to provide a high degree of driving stability while retaining sufficient traction.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
