Further information for automatic gearboxes
The engine is switched off when the selector lever is in position P, D/S or N or in manual mode. If the selector lever is in position P, the engine will remain off even if you take your foot off the brake. The engine will not start again until you select another gear and take your foot off the brake.
The engine will start again if you move the selector lever to R during a stop phase.
If you do not want the engine to start, move the selector lever quickly from D/S through R to P.
You can control whether or not the engine is switched off by varying the amount of pressure on the brake pedal. For instance, if you brake gently in stop-and-go traffic or before turning off at a junction, the engine will remain on while the Audi A4 is at a standstill. As soon as you press the brake pedal harder, the engine will be switched off.
Note
- Keep your foot on the brake pedal during a stop phase to prevent the Audi A4 from moving.
- If you press the START ENGINE STOP button* during a stop phase, the ignition will be switched off.
- If the engine stalls, you can start it again directly by pressing the clutch pedal immediately.
- The display differs slightly on some models.
