Applies to: vehicles with adaptive cruise control
Fig. 112 Operating lever: setting the distance
When approaching a vehicle driving ahead, the adaptive cruise control system brakes to match that vehicle's speed and then adjusts to the set distance. If the vehicle driving ahead accelerates, then the adaptive cruise control will accelerate up to the speed that you have set.
The newly-set distance will be shown briefly, for example with the indicator light.
If you adjust the speed, you must also change the time gap to the vehicle driving ahead. The higher the speed, the greater the distance that is needed.
The following distances can be set:
WARNING
Observe the safety precautions and note the limits of the assist systems, sensors, and cameras.
Tips
Depending on the driving situation and how the vehicle ahead is driving, the actual distance may be more or less than these target distances.
Overriding control
Applies to: vehicles with adaptive cruise control
Fig. 113 Lever: overriding the control
Requirement: adaptive cruise control must be switched on.
Overriding control
You can completely override the control, for example when passing or if you would like to accelerate more quickly.
When you are in the Driver assistance display, the message Overridden will appear.
Decreasing the distance
The function decreases the set distance and provides assistance, for example when merging when a lane is ending.
The adaptive cruise control reduces the distance and, if necessary, accelerates the vehicle above the set speed. When you are in the Driver assistance display, the message Overridden will appear.
WARNING
Driving in stop-and-go traffic
Applies to: vehicles with adaptive cruise control

Stopping with adaptive cruise control
The adaptive cruise control system also assists you in stop-and-go traffic1). Within the limits of the system, your vehicle may brake and remain at a stop if a vehicle driving ahead stops.
1) Depending on the engine
Starting to drive with adaptive cruise control
As long as the message ready to drive and is displayed, your vehicle will begin driving when the vehicle ahead starts to move .
The touching of the steering wheel will be evaluated in stop-and-go traffic. If the driver has at least one hand on the steering wheel, the driver will be considered ready for driving, and the "ready to drive" status can be extended.
If your vehicle is stopped for too Long, it will no longer drive autonomously for safety reasons, and the message will turn off.
Safe start monitor
Applies to: vehicles with safe start monitor
The vehicle can still start to drive even if certain obstacles are detected when starting to drive . If the surrounding area detection detects an obstacle, you will be alerted to the danger by the indicator light.
If you are in the Driver assistance display, the (1) fig. 114 and the message Warning! will also appear. An audio signal will also sound.
Your vehicle will drive more slowly when starting.
This may also occur in some situations when there is no apparent obstacle.
WARNING
Tips
For safety reasons, the adaptive cruise control only controls actively if:
Driver intervention request
Applies to: vehicles with adaptive cruise control
Fig. 115 Instrument cluster: request for driver intervention
The request for driver intervention instructs you to take over if the adaptive cruise control braking function is not able to maintain a sufficient distance to the vehicle driving ahead. The system will warn you of the hazard with the indicator light and the message Distance! An audio signal will also sound.
The display (1) only appears when the Driver assistance display is open in the trip computer.
WARNING
Observe the safety precautions and note the limits of the assist systems, sensors, and cameras.
