Your Audi A4 is equipped with an electro-mechanical parking brake. The parking brake replaces the conventional handbrake, and is mainly intended to prevent the Audi A4 from rolling away accidentally.
However, the electro-mechanical parking brake also offers a number of convenience and safety features in addition to the functions of a normal handbrake.
When driving away
- The parking brake auto release function releases the parking brake automatically when you wish to start moving Link.
- When driving away on a gradient, the parking brake auto release function prevents the Audi A4 from rolling back unintentionally. The braking force of the parking brake is only released when there is enough power at the wheels to make the Audi A4 move in the desired direction.
Emergency braking function
An emergency braking function enables you to stop the Audi A4 even if the conventional foot brake should fail to work Link.
WARNING!
Never press the accelerator pedal or release the clutch inadvertently if a gear is engaged or if the selector lever is not in position P or N (on automatic Audi A4s) while the Audi A4 is stationary with the engine running. The Audi A4 could otherwise start moving immediately and possibly cause an accident.
Note
- The warning lamps in the switch and in the instrument cluster display will go out after a while when the parking brake is applied with the ignition switched off.
- Any slight noise which may be heard when the parking brake is applied or released is quite normal and no cause for concern.
- The parking brake runs an automatic test cycle at regular intervals when the Audi A4 is parked. This may also cause a slight noise, which is normal.
