The ESC is switched on automatically when the engine is started.
The ESC operates in several levels. Depending on which level is selected, the stabilising function of the ESC is restricted or switched off, and the Audi A4 is stabilised to a greater or lesser degree.
In the following special situations, it may be advisable to switch on the sport mode (Saloon/Avant) or off-road mode (allroad) to allow a certain amount of wheelspin:
- Rocking the car backwards and forwards to free it
- Driving in deep snow or on loose surfaces
- Driving with snow chains
- allroad: Driving on rough terrain when much of the car's weight is lifted off the wheels (axle articulation)
- allroad: Braking on unsurfaced tracks when driving downhill

The traction control system (ASR) can only be switched off at speeds below 50 km/h on Audi A4s with front-wheel drive. At 70 km/h it will switch on again automatically. The ASR can be deactivated at any speed on Audi A4s with four-wheel drive.
You should switch on the sport mode/off-road mode or switch off the ESC/traction control system (ASR) only if your driving ability and the traffic conditions allow you to do so safely - danger of skidding!
- The stabilising function is restricted when sport mode/off-road mode is switched on. The driven wheels may start to spin, causing the Audi A4 to lose grip, in particular on slippery or wet roads.
- allroad: You should switch on the off-road mode only when driving off-road.
- Saloon/Avant: When the ESC/traction control system (ASR) is switched off, the Audi A4 will not be stabilised.
Note
The ESC/traction control system (ASR) cannot be switched off and the sport mode/off-road mode cannot be switched on when the cruise control system* or adaptive cruise control* is on.
