The start/stop system can help to save fuel and reduce CO2 emissions.
In start/stop mode, the engine is switched off automatically when the Audi A4 stops, e.g. at traffic lights. The ignition remains on during this stop phase. The engine is automatically started on demand.
The start/stop system is automatically activated each time you switch on the ignition.
Basic conditions for start/stop mode
- The driver's door must be closed.
- The driver's seat belt must be buckled.
- The bonnet must be closed.
- The Audi A4 must have been moving at over 4 km/h since the last stop.
- A trailer must not be hitched up to the Audi A4.
WARNING!
- Never let the car coast with the engine switched off. Otherwise you may not have the full benefit of the brake servo and power steering. You may need more strength to steer and brake the Audi A4 than you normally would. This would mean a greater risk of accidents and serious injury, because you cannot steer and brake in the normal manner.
- To avoid injury, make sure that the start/stop system is switched off before working in the engine compartment Link.
Caution!
Always switch off the start/stop system Link before driving through water.
