146 Driving systems Distronic displays in the speedometer The intermittent warning sound ceases and the distance warning lamp · goes out when the necessary distance to the vehicle ahead is established again. G Warning! When the Distronic is activated, one or two cruise control speed segments come on around set speed :. The vehicle speed displayed on the speedometer can briefly vary from the speed setting on the Distronic system. An intermittent warning sounds and the distance warning lamp · in the instrument cluster is illuminated if the Distronic system calculates that the distance to the vehicle ahead and your vehicle's current speed indicate that the Distronic will not be capable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision. Immediately brake the vehicle to increase your distance to the preceding vehicle. The warning sound is intended as a final caution in which you should intercede with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking. This will result in potentially dangerous emergency braking which will not always result in an impact being avoided. Tailgating increases the risk of an accident. Controls in detail G Warning! When the Distronic detects a vehicle directly ahead, the cruise control speed segments ; appear in the speedometer. These segments represent the difference between the set speed of your vehicle : and the speed of the preceding vehicle =. If the Distronic calculates that there is a danger of collision, the distance warning lamp · in the instrument cluster comes on and an intermittent warning sounds. X Immediately apply the brakes to avoid a collision. Under no circumstances should the driver await the intermittent warning sound before braking. The Distronic brakes your vehicle with a maximum deceleration of 6.5 ft/s2 (2 m/s2). This corresponds to approximately 20% of the maximum deceleration of your vehicle. You must also apply the brakes yourself to avoid a collision. The Distronic brakes the vehicle in an effort to restore the preset distance or to maintain the set speed. The brake pedal is automatically applied as this happens which results in the brake pedal moving Keep driver's foot area clear at all times, including the area under the brake pedal. Objects stored in this area may impair pedal movement which could interfere with the braking ability of the Distronic system. Do not place your foot under the brake pedal - your foot could become caught.
