G WARNING The DISTRONIC PLUS switches off and releases the brakes when the vehicle decelerates below the minimum speed of 20 mph (30 km/h) by operation of the system unless the 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.

Tips for driving with DISTRONIC PLUS Important safety notes The following contains descriptions of certain road and traffic conditions in which you must be particularly attentive. In such situations, brake if necessary. DISTRONIC PLUS is then deactivated. 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.

Cornering, going into and coming out of a bend

The ability of DISTRONIC PLUS to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or late.

158 Driving systems

Vehicles traveling on a different line

because of its narrow width. The distance to the vehicle in front will be too short. Obstructions and stationary vehicles

DISTRONIC PLUS may not detect vehicles traveling on a different line. The distance to the vehicle in front will be too short. Other vehicles changing lane

DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these. Crossing vehicles

DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short. Narrow vehicles

DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the road,

DISTRONIC PLUS may mistakenly detect vehicles that are crossing your lane. Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally.

Possible causes/consequences and M Solutions PARKTRONIC has malfunctioned and has switched off. X If problems persist, have PARKTRONIC checked at a qualified

specialist workshop.

The PARKTRONIC sensors are dirty or there is interference. X Clean the PARKTRONIC sensors (Y page 273). X Switch the ignition back on. The problem may be caused by an external source of radio or ultrasound waves. X See if PARKTRONIC functions in a different location.

Parking Guidance Important safety notes i Parking Guidance is only available in

Canada.

Parking Guidance is an electronic parking aid with ultrasound. Ultrasound is used to measure the road on both sides of the vehicle. A suitable parking space is indicated by the parking symbol. You receive steering instructions when parking. You may also use PARKTRONIC (Y page 162).

G WARNING Parking Guidance is merely an aid and may display parking spaces that are not suitable for parking, for example: Rno-parking areas Rparking spaces with unsuitable surfaces

(road surface)

Rdriveways Rentrances and exits Parking Guidance detects and measures potential parking spaces while driving past. Changes to the parking space after this point are not taken into account, for example if the vehicle in front of or behind the parking space changes position or objects in the parking space are moved. Even when using Parking Guidance, you are still responsible for driving carefully. If you rely on Parking Guidance alone, you could

166 Driving systems

cause an accident and injure yourself and others. Safety always remains your responsibility and you must continue paying careful attention to your immediate surroundings when parking and maneuvering. G WARNING Objects located above the height range of Parking Guidance will not be detected when the parking space is measured. These objects are not taken into account when the parking procedure is calculated, e.g. overhanging loads, tail sections or loading ramps of goods vehicles. Under some circumstances, Parking Guidance might therefore issue steering instructions too soon. This may lead to a collision. For this reason, you should avoid using Parking Guidance in such situations. G WARNING Make sure that no persons or animals are in the maneuvering range. Otherwise, they could be injured.

! Pay particular attention to low objects or

objects with flat surfaces, such as trailer drawbars, posts, cross beams and curbs. These types of objects cannot be detected by Parking Guidance and may damage the vehicle.

When PARKTRONIC is deactivated, Parking Guidance is also unavailable. Use Parking Guidance for parking spaces: Rthat are parallel to the direction of travel Rthat are on straight roads, not bends Rthat are on the same level as the road, i.e. not on the pavement, for example. Parking Guidance may not detect flat curbs

Parking tips: Ron narrow roads, drive past the parking

space as close as possible.

Rparking spaces that are littered, overgrown

or partially occupied by trailer drawbars might be identified incorrectly or not at all.

Rsnowfall or heavy rain may lead to a parking

space being measured inaccurately.

Rpay attention to the PARKTRONIC

(Y page 163) warning messages during the parking procedure.

Rwhen transporting a load which protrudes from your vehicle, you must not use Parking Guidance.

Rnever use Parking Guidance with snow

chains or an emergency spare wheel mounted.

Rmake sure that the tire pressures are

always correct. This has a direct effect on the steering instructions.

Rthe way your vehicle is positioned in the parking space after parking is dependent on various factors. These include the position and shape of the vehicles parked in front and behind it and the conditions of the location. In some cases, Parking Guidance may guide you too far or not far enough into a parking space. In some cases, it may also lead you across or onto the curb. If necessary, cancel the parking procedure with Parking Guidance.

! If unavoidable, you should drive over

obstacles such as curbs slowly and not at a sharp angle. Otherwise, you may damage the wheels or tires.

Detecting a parking space

: Detected parking space on the left ; Parking symbol = Detected parking space on the right Parking Guidance is automatically activated when you drive forwards. The system is operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the

system independently locates and measures parking spaces on both sides of the vehicle. When driving at speeds below 19 mph (30 km/h), you will see parking symbol ; as a status indicator in the instrument cluster. When a parking space has been detected, an arrow towards the right = or the left : also appears. Parking Guidance only displays parking spaces on the front-passenger side as standard. Parking spaces on the driver's side are displayed as soon as the turn signal on the driver's side is activated. To park on the driver's side, you must leave the driver's side turn signal switched on until you have engaged reverse gear. Parking Guidance will only detect parking spaces: Rthat are parallel to the direction of travel Rthat are at least 5 ft (1.5 m) wide Rthat are at least 4.3 ft (1.3 m) longer than

your vehicle

A parking space is displayed while you are driving past it, and until you are approximately 50 ft (15 m) away from it.

Parking G WARNING The Parking Guidance is only an aid and may not detect all obstacles. The Parking Guidance does not relieve you of the responsibility to pay attention. You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and maneuvering. Otherwise, you could endanger yourself and others.

ATTENTION ASSIST Important safety notes ATTENTION ASSIST helps you during long, monotonous journeys such as on freeways and interstate highways. It is active in the range between 50 mph (80 km/h) and 112 mph (180 km/h). If ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests you take a break. G WARNING ATTENTION ASSIST is only an aid and may detect your tiredness or lapses in concentration too late or not at all. It is not a substitute for a well-rested and attentive driver. Fatigue may cause you to recognize hazardous situations too late, misjudge a situation or react more slowly. For this reason, make sure you feel rested before you begin driving and during your journey. Make sure that you take regular breaks in time, particularly on long journeys. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

ATTENTION ASSIST assesses your level of fatigue or lapses in concentration by taking the following criteria into account: Ryour personal driving style, e.g. steering

characteristics

Rdriving conditions, e.g. time, driving time

170 Driving systems

The functionality of ATTENTION ASSIST is restricted and warnings may be delayed or not occur at all: Rif the road condition is poor, e.g. if the

surface is uneven or if there are potholes

Rif there is a strong side wind Rif you have adopted a sporty driving style with high cornering speeds or high rates of acceleration

Rif you predominantly drive at speeds under

50 mph (80 km/h) or over 112 mph (180 km/h)

Rif you are currently using COMAND or

making a telephone call with it

Rif the time has been set incorrectly Rin active driving situations, such as when you change lanes or change your speed

Warning and display messages in the multifunction display

X Activate ATTENTION ASSIST using the on-

board computer (Y page 193). Symbol : appears in the multifunction display.

If ATTENTION ASSIST is active, you will be warned no sooner than 20 minutes after your journey has begun. You will then hear an intermittent warning tone twice, and the Attention Assist: Drowsiness Detected message appears in the multifunction display. X If necessary, take a break. X Press a to confirm the message. On long journeys, take regular breaks in good time to allow yourself to rest properly. If you do not take a break and ATTENTION ASSIST still detects typical indicators of fatigue or

increasing lapses in concentration, you will be warned again after 15 minutes at the earliest. ATTENTION ASSIST is reset when you continue your journey and starts assessing your tiredness again if: Ryou switch off the engine. Ryou take off your seat belt and open the

driver's door, e.g. for a change of drivers or to take a break.

Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 170) and Lane Keeping Assist (Y page 172).

Blind Spot Assist Important safety notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It supports you from speeds of approximately 20 mph (30 km/h). A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible collision warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes. G WARNING Blind Spot Assist is only an aid designed to assist driving. It may fail to detect some vehicles and is no substitute for attentive driving. Blind Spot Assist cannot detect road and traffic conditions. It may fail to detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late. Monitoring may be affected by dirty sensors, strong spray or poor visibility caused by snow,

This device has been approved by the FCC as a “Vehicular Radar System”. The radar sensor is intended for use in an automotive radar system only. Removal, tampering, or altering of the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way. Any unauthorized modification to this device could void the user’s authority to operate the equipment.

For Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 196) and operational. Monitoring range of the sensors Blind Spot Assist monitors the area shown in the figure up to 10 ft (3 m) behind and immediately adjacent to your vehicle.

G WARNING Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles

that approach and drive past at high speeds are not detected. There is no display and no warning. If the lanes are very wide, it may not be possible to monitor the complete width of the neighboring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation. This may be the case if vehicles are driving at that edge of their lane which is furthest away from your vehicle. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if the vehicles are driving on the inner side of their lane. Due to the nature of the system: Rwarnings may be issued in error when

driving close to crash barriers or similar solid lane borders.

Rwarnings may be interrupted when driving alongside long vehicles, such as trucks, for a prolonged time.

The two sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free from dirt, ice or slush around the sensors. The rear sensors must not be covered, for example by bicycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. Blind Spot Assist may otherwise not work properly.

Indicator and warning display

: Yellow indicator lamp/red warning lamp When Blind Spot Assist is activated, indicator lamp : lights up yellow in the exterior mirrors up to a vehicle speed of 20 mph (30 km/h). When the vehicle speed exceeds 20 mph (30 km/h), the indicator lamp goes out and Blind Spot Assist is ready for use. When your speed exceeds approximately 20 mph (30 km/h), warning lamp : lights up red on the corresponding side whenever a vehicle is detected in the blind spot monitoring range. This warning is always given when a vehicle enters the blind spot monitoring range from behind or from the side. When you are passing another vehicle, the warning is emitted only if the difference in speed is less than 7 mph (12 km/h). The yellow indicator lamp goes out if reverse gear is engaged. In this event, Blind Spot Assist is no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. G WARNING Blind Spot Assist is not active at speeds under approximately 20 mph (30 km/h). The indicator lamps in the exterior mirrors are yellow. Vehicles in the monitoring range are then not indicated. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the turn signal, a double warning tone sounds. Red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones. Switching on Blind Spot Assist X Make sure that the radar sensor system

(Y page 196) and Blind Spot Assist (Y page 193) are activated in the on-board computer.

the miles display unit is selected, the assistance range begins at 40 mph. G WARNING Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid and may detect the lane markings on the road incorrectly or not at all. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to

insufficient illumination of the road, or due to snow, rain, fog or spray.

Rthere is glare, e.g. from oncoming traffic, the sun, or reflection from other vehicles.

Rthe windshield is dirty, fogged up or

covered, for instance by a sticker, in the vicinity of the camera.

Rseveral or no lane markings for a single lane

are present.

Rthe lane markings are worn away, dark or

covered up, e.g. by dirt or snow.

Rthe distance to the vehicle in front is too

small and the lane markings thus cannot be detected.

Rthe lane markings on the road are unclear,

e.g. near roadworks.

Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge.

Rthe road is narrow and winding. Lane Keeping Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

A warning can be given when a front wheel passes over a lane marking. It will warn you

by means of intermittent vibration in the steering wheel for up to 1.5 seconds. In order that you are warned only when necessary and in good time if you cross the lane marking, the system recognizes certain conditions and warns you accordingly. The warning vibration occurs earlier if: Ryou approach the outer lane marking on a

bend.

Rthe road has very wide lanes, e.g. a

freeway.

Rthe system recognizes solid lane markings. The warning vibration occurs later if: Rthe road has narrow lanes. Ryou cut the corner on a bend. No warning vibration occurs if: Ryou clearly and actively steer, brake or

accelerate.

Ryou cut the corner on a sharp bend. Ra driving safety system intervenes, e.g.

ABS, BAS or ESP®.

Ryou switch on the turn signals. In this event, the warnings are suppressed for a certain period of time.

For Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 196) and operational. Monitoring area Active Blind Spot Assist monitors the area shown in the figure up to 10 ft (3 m) behind and immediately adjacent to your vehicle. For this purpose, Active Blind Spot Assist uses radar sensors in the rear bumper.

Active Driving Assistance package General notes The Active Driving Assistance package consists of DISTRONIC PLUS (Y page 148), Active Blind Spot Assist (Y page 174) and Active Lane Keeping Assist (Y page 177).

Active Blind Spot Assist Important safety notes Active Blind Spot Assist uses a radar sensor system to monitor the side areas of your vehicle which are in back of the driver. A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible collision warning. If a risk of lateral collision is detected, corrective braking may help you avoid a collision. To support the course- correcting brake application, Active Blind Spot Assist also uses the forward-facing radar sensor system. Active Blind Spot Assist supports you from speeds of approximately 20 mph (30 km/h). G WARNING Active Blind Spot Assist is only an aid, and may detect vehicles/obstacles incorrectly or not at all. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to snow,

rain, fog or spray.

Rthe rear and/or front sensors are dirty. Active Blind Spot Assist may not detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late. It cannot detect vehicles that are overtaken at a small distance and then enter the blind spot area. Active Blind Spot Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the

G WARNING Active Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles that approach and drive past at high speeds are not detected. No visual nor audible warnings are emitted and the system does not brake the vehicle to correct your course. If the lanes are very wide, it may not be possible to monitor the complete width of the neighboring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation. This may be the case if vehicles are driving at that edge of their lane which is furthest away from your vehicle. Always pay attention to traffic conditions and your surroundings.

Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

Visual and audible collision warnings If you switch on the appropriate turn signals and a vehicle is detected in the side monitoring range, you will receive a visual and acoustic collision warning. You will hear a double warning tone and red warning lamp : flashes. If the turn signal remains on, vehicles detected are indicated by the flashing of red warning lamp :. There are no further warning tones. Course-correcting brake application If Active Blind Spot Assist detects a risk of a lateral collision in the monitoring range, a course-correcting brake application is carried out. This is meant to assist you in avoiding a collision. The course-correcting brake application is available in the range between 20 mph (30 km/h) and 120 mph (200 km/h). If a course-correcting brake application occurs, red warning lamp : flashes in the exterior mirror and the following is shown in the multifunction display, for example:

and apply the brakes. Active Blind Spot Assist does not detect all traffic situations and road users. Always make sure that there is sufficient distance on the side for other traffic or obstacles. An inappropriate brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate. You are responsible for driving at appropriate speeds, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

There will be either no or only a weak course- correcting brake application if: Rthere are vehicles or obstacles, e.g. crash

barriers, located on both sides of your vehicle.

Ra vehicle approaches you too closely at the

side.

Ryou have adopted a sporty driving style with

high cornering speeds.

Ryou clearly brake or accelerate. Ra driving safety system intervenes, e.g.

ESP® or PRE-SAFE® Brake.

RESP® is switched off. Ra loss of tire pressure or a defective tire is

detected.

G WARNING Active Blind Spot Assist is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the course-correcting brake application is not sufficient to avoid a collision. In such a case, you must steer, brake or accelerate. In very rare cases, the system may erroneously detect a danger of collision in the area of crash barriers or similar lane borders
