2019 Audi A4 Driver assistance

The intersection of 
awareness and support.
Because you can’t see everything, we developed Audi pre sense®, a host of features that help alert you as well as assist you in a variety of situations. Using cameras and radar sensors, Audi pre sense can help alert you to what’s around you.[1]
An elevated presence 
of mind.
Audi pre sense® helps monitor driving conditions around your vehicle with a sophisticated front-facing camera and available front/rear-facing radar and ultrasonic sensors.[1]

Audi pre sense® basic

Standard on all Audi A4, A4 allroad® and S4 models, Audi pre sense basic can begin closing the side windows and sunroof, as well as tightening the front safety belts, in the case of an unexpected event on the road.[1]

Audi pre sense® city

Detect oncoming vehicles and pedestrians with standard Audi pre sense city, which can initiate emergency braking from speeds up to 52 mph to help avoid unforeseen collisions.[1]

Vehicle exit warning

Help prevent accidents with other vehicles or cyclists approaching from behind while the vehicle doors are open. Available Vehicle exit warning uses rear radar sensors to help alert the driver or passenger by monitoring traffic behind the vehicle.[1]

Back out of a parking space with increased confidence using the available Rear cross traffic assist, which helps detect rear traffic and alerts the driver or initiates braking if necessary.[1]

Audi adaptive cruise control with Traffic jam assist

Maintain a set following distance during changing traffic speeds. In low-speed traffic, this available system can provide guided acceleration, braking and steering to help support you in stressful traffic situations.[1]

Traffic sign recognition and head-up display

Available traffic sign recognition uses a camera-based system to help detect common road signs such as speed limits and school zones, and it can display the information on the available Audi virtual cockpit and head-up display.[1]

Audi side assist

Available Audi side assist uses radar sensors and two different optical warnings to help keep the driver informed about what is approaching from hard-to-see angles behind the vehicle.[1]

Audi active lane assist

The available Audi active lane assist helps detect when the vehicle begins to leave the lane without signaling. Then, through gentle, corrective steering efforts, it helps the vehicle remain in the lane and vibrates the steering wheel as an additional warning.[1]
