Controls in detail Driving systems Increasing distance Increasing the distance setting tells Distronic to maintain a greater following distance to the preceding vehicle. Turn distance setting switch 1 in direction of arrow 3. Decreasing distance Decreasing the distance setting tells Distronic to maintain a shorter following distance to the preceding vehicle. Turn distance setting switch 1 in direction of arrow 2. 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. Warning! 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.: a stopped vehicle in a traffic jam a disabled vehicle an oncoming vehicle The driver must always be alert, observe all traffic and intercede as required by means of steering or braking the vehicle. G 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). This means that: Your vehicle can pass another vehicle after you have changed lanes. While in a sharp turn or if the preceding vehicle is in a sharp turn, Distronic could lose sight of the preceding vehicle. Your vehicle could then accelerate to the previously selected speed. Warning! G Distronic should not be used in snowy or icy road conditions. 273
