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 347). 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.

350

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. It is the driver’s responsibility at all times to be attentive to the road, weather and traffic conditions. 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

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.

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 cover is 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.

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). Do not use the DISTRONIC Plus if you are driving on a road with steep uphill or downhill slopes. When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 247). Canadian law does not permit the use of the radar sensor system for vehicles from outside of Canada. When you switch off the radar sensor

DISTRONIC Plus displays in multifunction display

1 Speed of the vehicle ahead 2 Set speed 3 Distance warning lamp If the DISTRONIC Plus is activated, the marker 2 indicates the set speed. The vehicle speed displayed on the speedometer can briefly vary from the speed setting on the DISTRONIC Plus system. If the DISTRONIC Plus detects a vehicle directly ahead, the ring on the speedometer dial comes on between the speed of the vehicle ahead 1 and the set speed 2. If the DISTRONIC Plus calculates that there is a danger of collision, the distance warning

lamp l in the instrument cluster comes on and an intermittent warning sounds. X Immediately apply the brake to avoid a

collision. Under no circumstances should the driver await the intermittent warning sound before braking. See the following warning note. The intermittent warning sound ceases and the distance warning lamp l goes out when the necessary distance to the vehicle ahead is again established. G Warning! An intermittent warning sounds and the distance warning lamp l 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. 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 Plus system.

Driving systems

Do not place your foot under the brake pedal – your foot could become caught. 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 drivers responsibility to apply the brakes in order to control the vehicle and avoid a collision.

carpets are securely in place.

RDo not rest your foot underneath the brake pedal, as it could otherwise be trapped.

You could otherwise cause an accident and injure yourself and/or others. G Warning! When the DISTRONIC Plus is switched on, the vehicle can be braked. You should therefore switch off the DISTRONIC Plus if the vehicle must be towed. You can activate the DISTRONIC Plus when the vehicle speed is above 20 mph (30 km/h). It is also possible to activate the DISTRONIC Plus when the vehicle speed is below 20 mph (30 km/h) and the DISTRONIC Plus has detected a preceding vehicle.

Controls in detail

Driving systems The maximum vehicle speed you can set is 120 mph (Canada: 200 km/h). When the DISTRONIC Plus is activated, the set speed is indicated with a marker in the speedometer dial (Y page 352).

It is helpful to switch on the DISTRONIC Plus display in the multifunction display (Y page 353) since you can only switch on the DISTRONIC Plus below a speed of 20 mph (30 km/h) when a preceding vehicle is detected.

You can adjust the set speed using the DISTRONIC Plus lever and the target distance using the distance setting switch on the DISTRONIC Plus lever (Y page 360). i If the DISTRONIC Plus is switched off, the PRE-SAFE® Brake (Y page 72) will warn of an impending collision if this function has been activated with the instrument cluster control system (Y page 244).

Starting off When the preceding vehicle starts off: X Remove your foot from the brake pedal. X Pull the DISTRONIC Plus lever briefly in

direction of arrow 4.

or X Briefly step on the accelerator pedal. Your vehicle starts off and adapts its speed to the preceding vehicle.

Driving If there is no preceding vehicle, the DISTRONIC Plus functions like the cruise control (Y page 347). When the DISTRONIC Plus detects that the preceding vehicle is driving more slowly, it

brakes the vehicle in order to keep the distance specified by you. When the DISTRONIC Plus detects that the preceding vehicle is driving faster, it accelerates the vehicle up to the set speed. G Warning! When you step on the brake pedal, you switch off the DISTRONIC Plus except when the vehicle is at a standstill. The DISTRONIC Plus will no longer brake your vehicle. You are always responsible for maintaining a distance from other vehicles, observing road speeds and braking well in advance.

Stopping G Warning! The braking effect of the DISTRONIC Plus is canceled and the vehicle can start to roll if Rthe DISTRONIC Plus is switched off using

The DISTRONIC Plus must never be operated or switched off by passengers or from outside the vehicle. The DISTRONIC Plus is not a substitute for the electronic parking brake and may not be used for parking. When you get out of the vehicle or switch off the engine, deactivate the DISTRONIC Plus and secure the vehicle from rolling away by engaging the electronic parking brake. When the DISTRONIC Plus detects that the preceding vehicle is stopping, the vehicle brakes until it also stops. Once the DISTRONIC Plus has stopped the vehicle and it is at a standstill, it remains stationary; the brake pedal does not need to be depressed.

Driving systems reduce vehicle speed further or bring it to a stop. Depressing the accelerator pedal does not deactivate the DISTRONIC Plus. After a brief acceleration (e.g. for passing), the DISTRONIC Plus will resume the last set speed.

Setting the following distance in DISTRONIC Plus You can set the specified following distance for the DISTRONIC Plus by varying the time setting between 1.0 and 2.0 seconds. Using this time setting and the current speed of your vehicle, the DISTRONIC Plus calculates and sets the required following distance to the preceding vehicle. The set distance will be shown in the multifunction display. G Warning! 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.

360

Driving with DISTRONIC Plus 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. Braking will deactivate the DISTRONIC Plus system. G Warning! The DISTRONIC Plus 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 your set distance). This means that: RYour vehicle can pass another vehicle

after you have changed lanes.

RWhile in a sharp turn or if the preceding vehicle is in a sharp turn, the DISTRONIC Plus could lose sight of the preceding vehicle. Your vehicle could then accelerate to the previously selected speed.

The DISTRONIC Plus regulates only the distance between your vehicle and those directly ahead of it. It may not register stationary objects in the road, e.g.: Ra stopped vehicle in a traffic jam Ra disabled vehicle Ran oncoming vehicle The driver must always be alert, observe all traffic and intercede as required by means of steering or braking the vehicle. G Warning! The DISTRONIC Plus should not be used in snowy or icy road conditions. The most likely cause for a malfunctioning system is a dirty sensor (located in the hood grille and in the bumper), especially at times of snow and ice or heavy rain. In such a case, the DISTRONIC Plus will switch off, and the message DISTRONIC PLUS Currently Unavailable See Oper. Manual appears in the multifunction display. For cleaning and care of the sensors, see (Y page 465). i If the message DISTRONIC PLUS

Currently Unavailable See Oper.

Manual disappears during driving and the last speed stored flashes for approximately 5 seconds, the dirt (e.g. slush) has dissolved; the DISTRONIC Plus is available again.

Another cause might be that the radar sensors have been manually switched off in the instrument cluster control system. Please verify that the radar sensors are switched on (Y page 247). Turns and bends

In turns or bends, the DISTRONIC Plus may not detect a preceding vehicle, or it may detect one too soon. This may cause your vehicle to brake late or unexpectedly.

Clean the sensors regularly, being careful not to scratch or damage the sensors, see “Cleaning the Parktronic system sensors” (Y page 465). G Warning! The Parktronic is a supplemental system. It is not intended to, nor does it replace, the need for extreme care. The responsibility during parking and other critical maneuvers always remains with the driver.

G Warning! Make sure no persons or animals are in or near the area in which you are parking/ maneuvering. Otherwise, they could be injured.

! Special attention must be paid to objects

with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, elevated crossbars or road curbs). Such objects may not be detected by the system and can damage the vehicle. During parking maneuvers, pay special attention to objects located above or below the height of the sensors (e.g. street curbs, painted posts, or trailer hitches etc.). The Parktronic system will not detect such objects at close range and damage to your vehicle or the object may result.

! Ultrasonic signals from outside sources

(e.g. truck air brakes, car wash, or jackhammers) may impair the operation of the Parktronic system.

Advanced Parking Guidance G Warning! The Advanced Parking Guidance is only an aid and may display parking spaces that are not suitable e.g. due to parking regulations, unsuitable road/ground surfaces, driveways, entrances/exits, etc. The Advanced Parking Guidance only shows a representation of the parking space in the instrument cluster display as parking space is first initially measured when driving past. Subsequent changes to the parking space are not taken into account, e.g. if the position of the vehicle parked in front of or behind the space changes or objects in the parking space are moved. Moving objects are not shown, e.g. pedestrians or vehicles driving past. The Advanced Parking Guidance does not relieve you of the responsibility to pay attention. If you only rely on the Advanced Parking Guidance, you may cause an accident and injure yourself and others. You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and maneuvering.
