What Does The Green Foot on Audi Mean?

Published by Dustin Babich on

The green foot symbol on an Audi dashboard is typically associated with the Start-Stop system feature. This system is designed to improve fuel efficiency and reduce emissions by automatically shutting off the engine when the vehicle comes to a stop, such as at traffic lights or in heavy traffic, and then restarting the engine when the driver is ready to move again, usually indicated by the release of the brake pedal.

When you see the green foot symbol illuminated, it’s an indication that the Start-Stop system is active and the engine has been temporarily turned off. This symbol is often accompanied by a message in the driver information system or on the dashboard display to inform the driver that the engine is in standby mode.

The Start-Stop system is designed to operate seamlessly and without driver intervention. However, if you prefer not to use this feature, most Audi vehicles allow you to deactivate the system manually via a button on the dashboard. It’s important to note that the system will automatically reactivate the next time you start the vehicle, as per the default settings in many Audi models.

If the Start-Stop system is not functioning as expected, or if the green foot symbol is flashing or accompanied by other warning lights, it may indicate a fault with the system. In such cases, it’s advisable to consult the vehicle’s manual or contact an Audi dealership or qualified mechanic for further assistance.

Introduction to Audi’s Start-Stop System

Reactivation of the Engine

The engine restarts automatically when the brake pedal is released or the accelerator pedal is pressed, readying the vehicle for immediate movement without noticeable delay.

Manual Deactivation

For drivers who prefer not to use the Start-Stop system, Audi provides an option to manually deactivate it, typically via a dedicated button on the dashboard.
