This function provides a warning from a speed of approximately 20 mph(30 km/h), if:

• for a period of several seconds, the distance to the vehicle in front is too short for the speed at which you are traveling.

The distance warning lamp in the instrument cluster will light up.

• you are rapidly approaching the vehicle in front. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster.

You must apply the brakes yourself in order to maintain the appropriate distance to the vehicle in front and prevent a collision.

WARNING  
If the distance warning lamp in the instrument cluster comes on while driving and/or an intermittent warning sounds, immediate attention on the part of the driver is required. As required by the traffic situation, apply the brakes and navigate around a possible obstacle. However, do not drive by relying on the distance warning function, as this will result in an emergency braking application. This will not always enable you to avoid a collision, especially when traveling on varying road surface conditions and with varying driver reaction.
Complex driving situations are not always fully recognized by the distance warning function. This could result in wrong or missing distance warnings.

► To activate/deactivate: activate or deactivate the distance warning function in the on-board computer.

After activation, the symbol is displayed in the lower multifunction display.
