DTC: Dynamic Traction Control

The customer can also order "Dynamic Traction Control DTC" as an option (SA5DT).

DTC is a drive-optimized version of DSC for certain road conditions. The dynamic traction control (DTC) provides improved traction with partially reduced driving stability and is thus only recommended for exceptional situations. In the following exceptional situations, it can be useful to activate DTC briefly:

• When 'rocking free' or driving off in deep snow or on loose ground.
• When driving on snow-covered upward inclines, in slush as well as on uncleared roads
• When driving with snow chains.

The function DTC corresponds to that of DSC with a slightly modified control strategy. DTC can be activated by shutting down DSC (DTC button). With brake intervention, DTC replicates the function of a conventional differential interlock. This effect of this is to increase the input torque on those wheels that are on a higher-friction surface. Advantage: Higher traction is available with DTC. Interventions to stabilize the vehicle (e.g. reduction in the engine output) are carried out slightly later than in the case of DSC. In certain situations, the driver must intervene correctively to stabilize the vehicle.
