Driving systems Crossing vehicles discrepancies while still parked. However, for significant level changes, e.g. after the vehicle has been stationary for a long period, the engine must be on. For safety reasons, the vehicle is only lowered when the doors are closed. Lowering is interrupted if a door is opened, and it continues once the door has been closed. 189 G Warning! DISTRONIC may detect vehicles that are crossing your lane by mistake. Activating DISTRONIC at, for example, a traffic light with crossing traffic, could cause your vehicle to pull away at the wrong time. Make sure that nobody is in the vicinity of the wheel arch or the underbody when changing the vehicle level. You could otherwise trap yourself or others. G Warning! Level control Important safety guidelines Level control automatically adapts the vehicle level to the current operating and driving situation. This results in reduced fuel consumption and improved handling. Vehicles with ADS: when you are driving in ADS COMF or ADS AUTO(Y page 194), the vehicle is automatically lowered to highspeed level as the speed increases. As the vehicle speed decreases, the vehicle is raised back up to highway level. In ADS SPORT(Y page 194), the vehicle skips highway level and is lowered directly to highspeed level. Make changes to the vehicle level while the vehicle is in motion. This enables the vehicle to adjust to the new level as quickly as possible. The vehicle level may change visibly if you park the vehicle and the outside temperature changes. If the temperature drops, the vehicle level is lower; with an increase in temperature, the vehicle level rises. When you unlock the vehicle or open a door, the vehicle begins to balance the load Always select as low a vehicle level as possible. If the vehicle level is high, the vehicle center of gravity shifts upwards. This increases the risk of the vehicle tipping over. Adapt your driving style to suit the vehicle level. ESP® cannot reduce the risk of an accident if you drive too fast. ESP® cannot override the laws of physics. ! When driving on extremely rough terrain, select a high vehicle level in good time. Make sure that there is always sufficient ground clearance to prevent damage to the vehicle. ! Remove the key from the ignition before raising one or more wheels with the appropriate equipment. Information on "Off-road driving"; see (Y page 173). Vehicles without the extended Off-Road Pro engineering package Basic setting The extent to which the vehicle is raised or lowered depends on the basic setting selected.
