This means that: RYour vehicle can pass another vehicle after It is up to the driver to exercise discretion to select the appropriate setting given road conditions, traffic, driver's preferred driving style and applicable laws and driving recommendations for safe following distance. you have changed lanes. RWhile Controls in detail in a sharp turn or if the preceding vehicle is in a sharp turn, the Distronic could lose sight of the preceding vehicle. Your vehicle could then accelerate to the previously selected speed. The Distronic regulates only the distance between your vehicle and those directly ahead of it, but does not register stationary objects in the road, e.g.: Ra Ra stopped vehicle in a traffic jam disabled vehicle oncoming vehicle Ran X Increasing distance: Turn distance setting switch : in direction of arrow =. Increasing the distance setting tells Distronic to maintain a greater following distance to the preceding vehicle. Decreasing distance: Turn distance setting switch : in direction of arrow ;. Decreasing the distance setting tells Distronic to maintain a shorter following distance to the preceding vehicle. The driver must always be alert, observe all traffic and intercede as required by means of steering or braking the vehicle. G Warning! X The Distronic should not be used in snowy or icy road conditions. Driving with Distronic This section describes a number of driving situations where special precaution is required on the part of the driver. Be prepared to brake in such situations. Braking will deactivate the Distronic system. The most likely cause for a malfunctioning system is a dirty Distronic system sensor cover (located in the hood grille), especially at times of snow and ice or heavy rain. In such a case, the Distronic will switch off, and the message DISTRONIC Currently Unavailable - See Operator's Manual appears in the multifunction display. For cleaning and care of the Distronic system sensor cover, see (Y page 263). G Warning! The Distronic works to maintain the speed selected by the driver unless a moving obstacle proceeding directly ahead of it in the same travel direction is detected (e.g. following another vehicle ahead of you at your set distance). i If the message DISTRONIC Available Again appears during driving, the dirt (e.g. slush) has dissolved; the Distronic works again, if you reactivate it (Y page 147).
