Predictive cruise control cannot detect all enforced maximum speed limits and may not react, or may react with a delay, or
may react in a way that is not desired. If you are careless, there is a risk of accidents, serious injuries and death.
Always stay attentive and do not rely solely on the system. The driver is always responsible for the stored speed of
the vehicle.
Observe the system limitations ⇒ System Limitations of Predictive Cruise Control .
Always adapt your speed to the visibility, weather, road and traffic conditions.
Keep the navigation data up to date.
Always observe the maximum permissible speed.
Note that the speeds regulated by the system do not necessarily conform to your driving style.
Also observe the system limitations of and information on ACC.
System Limitations of Predictive Cruise Control
Please read the introductory information and heed the Warnings and Notice ⇒
Introduction.
Beside the system limitations of the Dynamic Road Sign Display system and the system limitations of the ACC, predictive
cruise control also has the following additional, system-based limitations:
Predictive cruise control only detects road signs that display a speed limit. In particular, predictive cruise control does not
detect priority rules or traffic lights.
Road signs that display a speed limit indirectly, such as city limit signs, are only detected on the basis of the navigation
data.
Road signs with additional signs that, for example, show time limits are only taken into consideration if they are included
in the navigation data.
The predictive cruise control function is not available on roads that are either not included or not mapped with complete
accuracy in the navigation data.
If a speed limit is announced on the basis of the navigation data but not detected by the Dynamic Road Sign Display, the
announced speed is reset to the speed last saved.
Predictive cruise control cannot take over speeds below the minimum speed ⇒
Introduction.
Functional limitations
In the following situations, the predictive cruise control may not change the speed, may change it with a delay or in a way that
is not desired:
Dynamic Road Sign Display is malfunctioning. No speed limit
is displayed in the instrument cluster display.
Road signs are not being detected or are not being detected correctly.
The navigation data are out of date.
You are driving without route guidance.
You deviate from the route calculated by the navigation system.
The position of the vehicle cannot be determined correctly due to inaccurate GPS data.
Activating the predictive cruise control
Please read the introductory information and heed the Warnings and Notice ⇒
