The TPM+ (Tyre Pressure Monitoring) can detect and alert the driver to a drop in pressure below the critical threshold in any wheel/tyre. It uses data from the ABS revolution sensors on individual wheels. If the pressure in a tyre falls, the radius of that particular wheel changes compared to other wheels. The KODIAQ and SUPERB also offer the direct Tyre Pressure Monitoring.
TSA (Trailer Stability Assist) is a stabilizing system for vehicles towing a trailer. TSA is automatically supplied in cars with ESC and operates when the vehicle is equipped with an original towing device with its own control unit. The system works on the principle braking one or more wheels and simultaneously reducing engine torque as necessary. The TSA system intervenes and helps stabilize the car and the trailer.
The XDS+ (Electronic Differential Lock) helps the driver during sharp turns and ensures that the vehicle behaves neutrally during dynamic cornering. The control electronics essentially simulate the presence of a self-locking differential to improve traction and driving dynamics during turns. As a result, the vehicle will take bends much more assuredly and naturally than before.
