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
Operational between 0 and 155 mph, the adaptive cruise control uses radar sensors to maintain the required distance between your A4 and vehicle in front 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 40mph, to keep the vehicle in lane. Adaptive Cruise Control requires additional sensors in the lower front air inlets, and results in a change to the design of the inlets and differs dependent on trim. Stop&Go and Traffic-jam assist are only available when ordered with S tronic or tiptronic transmissions

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 Audi Virtual Cockpit. In combination with Adaptive Cruise Control (ACC), the system uses the route data and speed limits to adjust the ACC desired speed and cornering accordingly. With S tronic and tiptronic transmissions, the system activates free-wheeling mode or engine braking, which can help reduce fuel consumption and enhance ride comfort

Audi Pre-sense Front
Extends the collision warning and automatic braking function of Pre-sense City to cover the entire speed range up to 155 mph 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 Audi virtual cockpit. Detects the following signs: speed limits (including temporary limits), overtaking restrictions and no-entry warnings

Collision avoidance assistant
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 driver indicates and sets off up to a maximum speed of 6 mph, 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 from approximately 40 to a maximum of 155 mph
