DISTRONIC PLUS Safety notes When activated, the DISTRONIC PLUS adaptive cruise control system increases the driving convenience afforded by the cruise control while traveling on expressways and other major roadways. RIf the DISTRONIC PLUS distance sensor detects a slower moving vehicle directly ahead, your vehicle speed will be reduced
so that you follow that vehicle at your preset following distance.
RIf there is no vehicle directly ahead of you,
the DISTRONIC PLUS will function in the same way as standard cruise control (Y page 128). G Warning! The DISTRONIC PLUS requires familiarity with its operational characteristics. We strongly recommend that you review the following information carefully before operating the system. G Warning! The DISTRONIC PLUS is a convenience system. Its speed adjustment reduction capability is intended to make cruise control more effective and usable when traffic speeds vary. It is not however, intended to, nor does it, replace the need for extreme care. The responsibility for the vehicle’s speed, distance to the preceding vehicle and, most importantly, brake operation to ensure a safe stopping distance, always remains with the driver. The DISTRONIC PLUS cannot take street and traffic conditions into account. Complex driving situations are not always fully recognized by the DISTRONIC PLUS. This could result in wrong or missing distance warnings. G Warning! The DISTRONIC PLUS adaptive cruise control is not a substitute for active driving involvement. It does not react to pedestrians or on stationary objects, nor does it recognize or predict the curvature and lane layout or the movement of preceding vehicles. The DISTRONIC PLUS can only apply a maximum of 40% of the vehicle’s braking power. The DISTRONIC PLUS may not detect narrow vehicles possibly driving in front of you, such as motorcycles and vehicles driving in an offset formation.

Additionally, the driver must provide the steering, braking and other driving inputs necessary to remain in control of the vehicle. High-frequency sources such as toll stations, speed measuring systems etc. can cause the DISTRONIC PLUS system to temporarily cease functioning. G Warning! The DISTRONIC PLUS cannot take road and traffic conditions into account. Only use the DISTRONIC PLUS if the road, weather and traffic conditions make it advisable to travel at a constant speed. G Warning! Use of the DISTRONIC PLUS can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control. The DISTRONIC PLUS does not function in adverse sight and distance conditions. Do not use the DISTRONIC PLUS during conditions of fog, heavy rain, snow or sleet. G Warning! The DISTRONIC PLUS cannot take weather conditions into account. Switch off the DISTRONIC PLUS or do not switch it on if: Rroads are slippery or covered with snow or
ice. The wheels could lose traction while braking or accelerating, and the vehicle could skid.
Rthe DISTRONIC PLUS system sensor covers
are dirty or visibility is diminished due to snow, rain or fog, for example. The distance control system functionality could be impaired.
Always pay attention to surrounding traffic conditions even while the DISTRONIC PLUS is switched on. Otherwise, you may not be able to recognize dangerous situations until it is

too late. This could cause an accident in which you and/or others could be injured. G Warning! The “Resume” function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed. G Warning! Close attention to road and traffic conditions is imperative at all times, regardless of whether or not the DISTRONIC PLUS is activated. Use of the DISTRONIC PLUS can be dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a constant speed. The DISTRONIC PLUS will not react to stationary objects in the roadway (e.g. a stopped vehicle in a traffic jam or a disabled vehicle). The DISTRONIC PLUS will also not respond to oncoming vehicles. Switch off the DISTRONIC PLUS: Rwhen changing from the left to the right
lane if vehicles are moving more slowly in the left lane
Rwhen entering a turn lane or highway off
ramp
Rin complex driving situations, such as in
highway construction zones
In these situations, the DISTRONIC PLUS will continue to maintain the set speed unless deactivated. The DISTRONIC PLUS is designed and intended only to maintain a set speed and keep a set distance from moving objects in front of it. The DISTRONIC PLUS functions in a speed range of 0 to 120 mph (Canada: 0 to 200 km/h) if a preceding vehicle is detected. If no preceding vehicle is detected the DISTRONIC PLUS functions in a speed range of 20 to 120 mph (Canada: 30 to 200 km/h).

Version: 2.11.8.1when the necessary distance to the vehicle ahead is again established. G Warning! An intermittent warning sounds and the distance warning lamp · in the instrument cluster is illuminated if the DISTRONIC PLUS system calculates that the distance to the vehicle ahead and your vehicle’s current speed indicate that the DISTRONIC PLUS 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. G Warning! The DISTRONIC PLUS brakes your vehicle with a maximum deceleration of 13 ft/s2
(4 m/s2). This corresponds to approximately 40% of the maximum deceleration of your vehicle. You must also apply the brakes yourself to avoid a collision. The DISTRONIC PLUS brakes the vehicle in an effort to restore the preset distance or to maintain the set speed. G Warning! If you do not receive visual or acoustic warning signals during a critical traffic situation, DISTRONIC PLUS has either not recognized the collision risk, has been deactivated or is malfunctioning. Remember, whether or not DISTRONIC PLUS is operating, it is ultimately always the driversDriving systems
