- Fig. 1 Instrument cluster: SET button
This button has a number of different functions.
The SET button has the following functions:
Activating clock, date, temperature and mileage recorder displays
The display will appear for about 30 seconds if you press the SET button when the ignition is switched off.
Starting the auto-check control
The auto-check control checks important components and Audi A5 systems. These background checks are run constantly, as long as the ignition is switched on.
You can start the "check procedure" manually by pressing the SET button with the ignition switched on. This function check can be started at road speeds up to 5 km/h.
In addition, the number of keys initialised for your Audi A5 is displayed. L2 3/3 means that three keys have been initialised. This feature enables used car buyers to make sure they have received all of the keys.
If you are given only two keys, for instance, you should take the Audi A5 and the existing keys to an Audi dealer to have the missing key disabled. It is also important to notify your insurance company about the loss.
Setting speed warning
You can press the SET button briefly to set speed limit warning 1 while the Audi A5 is moving Link. If you press and hold the SET button, this will cancel the speed warning.
