Audi A4: Audi pre sense

Function overview

Applies to: vehicles with Audi pre sense

Within the limits of the system, the Audi pre sense functions can initiate measures in certain driving situations to protect the vehicle occupants and other road users. Depending on the vehicle equipment, various Audi pre sense systems may be installed:

  • Audi pre sense basic can react during emergency and dangerous braking maneuvers and unstable driving situations (such as over steering or understeering).
  • Audi pre sense city and Audi pre sense front can detect an impending frontal impact and react with warnings, braking interventions, and preemptive safety measures for the vehicle occupants.
  • Audi pre sense rear monitors the rear traffic behind your vehicle and can react to an impending rear impact.
  • The swerve assist can help you to steer the vehicle around an obstacle during an evasive maneuver that is detected as critical.
  • The turn assist can detect vehicles in the opposite lane as critical during a turning maneuver and react with braking maneuvers.
