Active Brake Assist 3 (ABA 3)
The Active Brake Assist or Advanced Emergency Braking System kicks in as soon as the foreseen distance from the vehicle ahead or a stationary obstacle falls dangerously below the safe distance. The systems, which exceed today's regulatory requirements, first warn the driver, and if he doesn't react, they independently initiate full braking.

Tire Pressure Monitoring (TPM)
Correctly filled tires contribute to driving safety and have a longer service life. The Tire Pressure Monitoring System (TPMS) helps to detect reduced pressure on one or more tires during driving. This can prevent tire damage and therefore increase safety as well as cost-effectiveness.

Predictive Powertrain Control (PPC)
PPC is a GPS speed control feature, which also intervenes in the automatic transmission control. Because the system knows the topography ahead, it can proactively optimise switching times and cruise speed.
