Applies to vehicles: with adaptive cruise control
Adaptive cruise control is a combined speed and distance control system to assist the driver.
The adaptive cruise control operates at speeds between 0 and 200 km/h. It allows you to maintain any desired constant speed between 30 and 200 km/h. When the speed of the vehicle drops below 30 km/h, the minimum speed setting of 30 km/h applies. In addition, the system controls the distance maintained to the vehicle in front (even when slowing to a standstill but subject to certain limitations).
The system can increase the level of comfort on long motorway journeys or on other main roads with long straight sections. In addition it assists the driver in heavy or stop-go traffic. However, please pay careful attention to the system limitations described below.
How is the system operated?
Driver messages
When the system is being used, important information is displayed in the speedometer and on the instrument cluster display screen Link.
Please always direct your full attention to the road, even when you are using adaptive cruise control. It is always the driver who is responsible for determining the speed and for keeping a safe distance to the other vehicles on the road.
- For safety reasons, the adaptive cruise control must not be used in city traffic, on roads with a lot of bends or in difficult driving conditions (such as ice, fog, loose grit or gravel, heavy rain, aquaplaning) - this could cause an accident!
- Adaptive cruise control will not react when approaching a stationary obstacle, e.g. the end of a traffic jam or a broken-down vehicle, or if a vehicle should come towards you in the same lane.
- When you take a turn-off, drive along a motorway exit lane or pass through roadwork sections, please temporarily switch off the adaptive cruise control in order to avoid the vehicle accelerating to the selected speed.
- The adaptive cruise control can only control the distance to vehicles in front. As a rule, it cannot recognize vehicles travelling in other lanes. For this reason, please temporarily switch off the system if you are travelling in the inside lane and vehicles in the overtaking lane are travelling at a slower speed than you are. Otherwise, you would overtake these vehicles on the inside.
- Please make sure you do not unintentionally rest your foot on the accelerator - this will override the adaptive cruise control system which, as a result, will not automatically brake the vehicle.
Note
- For safety reasons, the speed setting will be deleted when the ignition is switched off.
- Switching on the adaptive cruise control automatically activates the Electronic Stabilisation Program (ESP) and the traction control system (ASR). These two systems cannot be deactivated while the adaptive cruise control is switched on.
- Damage caused by impacts (e.g. if the vehicle is damaged when parking) can affect the radar sensor settings. This can cause the system to malfunction or switch off completely.
- The cover on the radar sensor is heated Fig. 1. However, in wintry conditions you should make sure that the cover is free of ice and snow before you set off. Notes on cleaning Link.
- To make sure that the radar sensor is fully operative, do not attach any objects (e.g. stickers, large registration plate mountings, racks or other mounting equipment) to the area surrounding the radar sensor Fig. 1. Moreover, this area should not be painted.
