Adaptive Cruise Control with Stop&Go and Traffic-jam assist
Automatic distance regulation, using radar sensors to maintain the required distance between vehicles ahead by braking and accelerating. Approximate control range: S tronic/tiptronic transmissions 0–155mph.* It includes Stop&Go function which brakes the car to a stop and can restart automatically again (subject to certain system limits). The driver can select from 5 distance thresholds and influence the systems acceleration behaviour via Audi Drive Select. This also includes Traffic-jam assist which detects vehicles ahead and on adjacent lanes to assist with the braking, acceleration and also steering up to approximately 40mph, to keep the vehicle in lane.

Predictive efficiency assistant
The system uses navigation data e.g. speed limits, traffic signs, road bends, junctions and roundabouts to give the driver efficiency advice in the instrument cluster (or via the optional Audi Virtual Cockpit). In conjunction with Adaptive Cruise Control (ACC), the system uses the route data and speed limits to adjust the ACC desired speed and cornering accordingly. The system activates free-wheeling mode or engine braking, which can help reduce fuel consumption and enhance ride comfort.

Pre-sense Front
Extends the collision warning and automatic braking function of Pre-sense City to cover the entire speed range (up to 155mph*) and can also increase braking initiated by the driver if this is inadequate. The system uses the camera located on the front rear-view mirror to detect vehicles and pedestrians in front in order to reduce severity of a collision, or if possible prevent an accident. The driver is first given a visual and acoustic warning followed by partial braking and then full brake application.

Turn assist
When turning at junctions, from the moment the turn indicators are activated, the turn assist system detects approaching vehicles and applies braking to help avoid a collision.

Active Lane Assist
Detects lane boundary markings and helps the driver to stay in lane with gentle steering intervention for greater safety and convenience, particularly on motorways. Works at speeds above approximately 40mph.

Please note: Vehicle driver assistance and safety systems are not a substitute for attentive driving.
