- Fig. 110 Instrument cluster: Predictive control
Description
The predictive control1) uses map information from the navigation system to anticipate the route and drive accordingly. Information from the camera-based traffic sign recognition* system is also applied link►.
When it detects an impending speed limit or a change in the road ahead (e.g. a bend, intersection or roundabout), the system applies the brakes automatically and accelerates again afterwards up to the cruising speed.
(Automatic gearbox:) It also uses the intelligent coasting function for automatic cruise control link►.
Overriding the regulating function
The driver can override the predictive control at any time by pressing the accelerator or brake pedal. In addition, the operating lever
fig.► can be used to change the speed limit control response. The predictive control is deactivated if the driver makes a significant change to the speed limit control response. The adaptive cruise control regulates the speed to match the desired value.
Always switch off the predictive control in the following situations:
- In situations requiring extra care and attention from the driver.
- In poor weather, for instance in snow or heavy rain.
- In poor road conditions.
Display in the instrument cluster
When the adaptive cruise control is switched on initially, the availability of the predictive control is indicated in the status line by a driver message.
When a speed limit is detected and the vehicle speed adjusted accordingly, the symbol 
70 
appears. In this case, the system will regulate the speed to 70 km/h. This speed is then applied by the adaptive cruise control. The LEDs in the speedometer dial will be adjusted to match the new cruising speed
fig.►.
When a change in the road is detected and the vehicle speed adjusted accordingly, the symbol 
Fig. 110► appears.

WARNING
- Always direct your full attention to the road and surroundings, even when you are using the predictive control. It is always the driver s responsibility to assess the traffic situation and take appropriate care.
- The system does not give way to priority traffic and does not stop at traffic lights - risk of accident!
- The system only responds to traffic signs specifying a speed limit.
- A speed limit infringement may occur if the system responds incorrectly to a speed limit. As the driver you are always responsible for keeping within the maximum speed limit.
- The speed at which the system drives the vehicle through a corner may not correspond to your own driving style. Apply the brakes manually as appropriate - risk of accident!
Note
- The set speed in the LEDs on the speedometer dial is adjusted when a speed limit is detected even when the adaptive cruise control is inactive.
- When the vehicle is coasting, the actual road speed may occasionally exceed or fall below the set speed.
- The system s control response depends on the driving mode set in drive select*.
- The deactivation of the predictive control, e.g. when entering a traffic-calming zone, does not cause the deactivation of the adaptive cruise control.
- When you switch on the ignition and subsequently enter a motorway with no speed limit, the system initially regulates the speed to 130 km/h. After this, the last speed stored by the driver is applied.
- Predictive control does not occur in areas with speed limits below 30 km/h.
- If a speed limit is only detected by the camera and you are driving at a much faster speed, the speed limit will flash on the display until the vehicle reaches the specified speed link►.
- If incorrect values are supplied by the camera-based traffic sign recognition* or if the map material on the navigation system is out of date, this can cause failures or implausibilities in the control response.
- While route guidance is active on the navigation system, the control uses the navigation route as a reference. Implausibilities in the control response can occur when route guidance is inactive or if you leave the route.
- The system is automatically deactivated when you leave the road area mapped on the navigation system.
