2014 Audi A4 / S4 — Owner's Manual
If the engine should not start immediately, the starting process is automatically stopped after a short time. Repeat starting procedure. When starting the engine, major electrical loads are switched off temporarily. After a cold engine is started, there may be a brief period of increased noise because oil pressure must first build up in the hydraulic valve adjusters.
This is normal and not a cause for concern. Your vehicle is equipped with an electromechanical parking brake. The parking brake is designed to prevent the ve hicle from rolling unintentionally and replaces the handbrake. In addition to the normal functions of a traditional handbrake, the electromechanical parking brake provides various convenience and safety functions.
When stopping at a traffic signal or stopp ing in city traffic on vehicles with an automatic transmission, the parking brake can be applied. The vehicle does not have to be held with the footbrake. The parking brake eliminates the tendency to creep with a drive range engaged. As soon as you drive off, as usual, the parking brake is released automatically and the vehicle starts to move.
