Audi A4: Cruise control system

Description

Applies to: vehicles with cruise control system

The cruise control system assists the driver in maintaining a constant speed above approximately 15 mph (20 km/h). The system maintains the desired speed by braking and accelerating.

WARNING

• Observe the safety precautions and note the limits of the assist systems, sensors, and cameras.
• The cruise control system is only an assist system, and the driver is still responsible for controlling the vehicle. The driver is especially responsible for braking, controlling the speed, and maintaining the distance to other vehicles.
• Switch the cruise control off temporarily when driving in turning lanes, highway exits, or in construction zones. This prevents the vehicle from accelerating to the stored speed when in these situations.

Note

Before driving downhill a long distance on a steep hill, decrease your speed and select a lower gear. This makes use of the engine braking effect and reduces the load placed on the brakes.
