Audi A4 (B9) 2016-2022 Owner's Manual: Start/Stop system


Applies to: vehicles with Start/Stop system

The Start/Stop system can help increase fuel economy and reduce CO2 emissions.

In Start/Stop mode, the engine shuts off automatically when stopped, for example at a traffic light. If certain conditions are met, the engine may stop before the vehicle has come to a complete stop. If you press the accelerator pedal when this happens, the engine will start and driving power will be transmitted.

The ignition and important assist systems such as the brake booster will remain available during the Stop phase. The engine will restart automatically when needed.

The Start/Stop system is automatically activated once the ignition is switched on.

Switching the Start/Stop system off and on

The button is located above the selector lever in the center console. The LED in the button turns on when the function is switched off.

If you switch the system off during a Stop phase, the engine will start again automatically.
