Audi Q5: Auto Check Control
Introduction
The Auto-Check control monitors the function of certain vehicle features and components. It simply makes sure these features and components are working properly. The Auto-Check control works as long as the ignition is on, as well as whenever the vehicle is driven.
If a component is malfunctioning or if the need for an urgent repair has been detected, this will appear in the instrument cluster display. You will also hear an audible warning tone. The displays are color coded in either red or yellow depending on their level of priority.
A red symbol means Danger, a yellow symbol indicates Warning. In certain situations, information message for the driver appear in addition to the red and yellow symbols.
Note about automatic transmission
The Auto-Check Control will automatically perform a test each time you switch on the ignition. With the selector lever in P or N, the following message appears in the display:
When stationary apply brake pedal while selecting gear
When you select a different gear (for example: R, D, etc.), the message will disappear and the Auto-Check function is displayed.
If there is a malfunction, then the malfunction message will appear about 15 seconds after you start the vehicle. At the same time you will hear a warning tone.
Driver information messages
Driver information messages are shown in the instrument cluster display in addition to symbols.
