If the vehicle has been stopped by DISTRONIC Plus and a malfunction occurs in the system, the message "Brake immediately" will appear on the multifunction display. Step on the brake immediately to prevent the vehicle from rolling. DISTRONIC Plus is then switched off and the message disappears. Setting the following distance in DISTRONIC Plus You can set the specified following distance for DISTRONIC Plus by varying the time setting between 1.0 and 2.0 seconds. Using this time setting and the current set speed of your vehicle, DISTRONIC Plus calculates and sets the required following distance to the vehicle ahead. The set distance will be shown in the multifunction display. Warning! Warning! G DISTRONIC Plus switches off and releases the brakes when the vehicle decelerates below the minimum speed of 20 mph by operation of the system unless DISTRONIC Plus detects a vehicle directly ahead of you. At that time the driver must apply the brakes in order to reduce vehicle speed further or bring it to a stop. ! Setting the automatic transmission to N while driving cancels the DISTRONIC Plus. However, the automatic transmission should not be set to N while driving except to coast when the vehicle is in danger of skidding (e.g. on icy roads). i Depressing the accelerator pedal does not deactivate DISTRONIC Plus. After brief acceleration (e.g. for passing), DISTRONIC Plus will resume the last speed set. G 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. 436
