## Setting the distance

The distance can be set in 4 different stages.

Control lever for: Setting the distance

– Briefly press the sliding switch ⇒ fig. 142 once towards + or -. The display
in the instrument cluster will briefly show the current distance setting.

– Press the sliding switch again towards + or - to increase or reduce the distance
by one level at a time.

Choosing the distance

The adaptive cruise control system determines the distance to the vehicle in front by time intervals. It defines a time-based distance to the vehicle in front which is kept at a constant level. This converts to a distance which depends on the speed - the higher the speed, the higher the safety distance in metres ⇒ .

The actual distance maintained by the adaptive cruise control can be longer or shorter, depending on the traffic situation and the driving style of the driver in front.

Distance 1

This setting is suitable for brisk driving in a line of traffic. The time interval is 1 second. This is equivalent to (for instance):

- • A distance of 14 metres at a speed of 50 km/h
- • A distance of 36 metres at a speed of 130 km/h

Distance 2

This setting is suitable for relaxed “moving with the flow” in a line of traffic. The time interval is 1.3 seconds. This is equivalent to (for instance):

- • A distance of 18 metres at a speed of 50 km/h
- • A distance of 47 metres at a speed of 130 km/h

Distance 3

This (recommended) setting is suitable for relaxed “moving with the flow” in a line of traffic. The time interval is 1.8 seconds. This is equivalent to (for instance):

- • A distance of 25 metres at a speed of 50 km/h
- • A distance of 65 metres at a speed of 130 km/h

Distance 4

This setting is suitable for single-carriageway roads. The time interval is 2.3 seconds. This is equivalent to (for instance):

- • A distance of 32 metres at a speed of 50 km/h
- • A distance of 83 metres at a speed of 130 km/h

You can control the acceleration and braking response of your vehicle in adaptive cruise control mode by adjusting the settings on the sound system or MMI*gggggg 139. Depending on the driving program and distance selected, acceleration and braking response will range from dynamic (1) to relaxed (5).

*WARNING*

**When setting the distance, the driver is responsible for adhering to the
laws and regulations which apply in the country he is travelling in.**
