With busier roads than ever, Audi technology can keep an extra eye out. This pack brings together the driver assistance systems that support long-distance driving, especially
when driving in congestion and varying average speed limit zones. As well as helping you to drive more efficiently, the pack also includes advanced safety systems.

Adaptive Cruise Control with Stop&Go and Traffic-jam assist
Automatic distance regulation, using radar sensors to maintain the required distance between your A4 allroad and vehicles ahead by braking and accelerating. With the Stop&Go function, the system brakes the car to a stop. The driver can select from 5 warning thresholds and influence the system’s acceleration behaviour via Audi Drive Select. Traffic-jam assist detects vehicles ahead and on adjacent lanes to assist with the braking, acceleration and also steering up to 37mph, to keep the vehicle in lane. Adaptive Cruise Control requires additional sensors in the lower front air inlets.

Pre-sense Front
Extends the collision warning and automatic braking function of Pre-sense City to cover the entire speed range 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.

Camera-based traffic sign recognition
Speed limit and traffic sign display via the Driver’s Information System (DIS) or optional Head-up display. Detects the following signs: speed limits (including temporary limits), overtaking restrictions and no-entry warnings.

Predictive efficiency assist
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.

Collision avoidance assist
Supports the driver’s actions during an avoidance manoeuvre, reducing the likelihood of a collision or of swerving off the road. The system provides additional steering torque and uses vehicle sensors to calculate the optimum path of avoidance.

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.

Audi 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 37mph.
Only available in combination with high-beam assist, and on allroad MMI Navigation.
Vehicle driver assistance and safety systems are not a substitute for attentive driving. Drivers retain full responsibility for providing the necessary inputs for safe control of the vehicle.
