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. This will deactivate the Distronic system. 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 on the alert, observe all traffic and intercede as required by 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 a distance set by Distronic). This means that: your vehicle can pass another vehicle after you change lanes while in a sharp turn or if the vehicle in front is in a sharp turn, Distronic could lose sight of a vehicle traveling in front of it, then your vehicle could accelerate to the previously selected speed. Warning! G Distronic should not be used in snowy or icy road conditions. 206
