Tips for driving with DISTRONIC PLUS Important safety guidelines 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).

Driving systems

301

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.

302 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 lanes

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

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

whenever a drive wheel spins due to insufficient grip. G Warning! If a drive wheel is spinning due to insufficient traction: RWhile driving off, apply as little throttle as

possible.

RWhile driving, ease up on the accelerator

pedal.

RAdapt your speed and driving style to the

prevailing road conditions.

Failure to observe these guidelines could cause the vehicle to skid. The 4MATIC cannot prevent accidents resulting from excessive speed.

! Never tow the vehicle with one axle

raised. This may damage the transfer case. Damage of this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels must remain either on the ground or be fully raised. Observe the instructions for towing the vehicle with all wheels in full contact with the ground.

i In wintry driving conditions, the maximum

effect of 4MATIC can only be achieved if you use winter tires (M+S tires), with snow chains if necessary.

PARKTRONIC Important safety notes 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.

PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is activated automatically when you: Rswitch on the ignition. Rshift the transmission to position D, R or

N.

Rrelease the electric parking brake. PARKTRONIC is deactivated at speeds above 11 mph (18 km/h). It is reactivated at lower speeds. PARKTRONIC monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper.

: Sensors in the front bumper, left-hand

Parking Guidance Important safety notes 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 307). 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 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! The system cannot detect objects located above the area that the sensors scan. These objects, e.g. protruding load, overhang, or truck tail lifts, will be ignored when computing the parking procedure. The Parking Guidance might therefore provide untimely steering instructions. This could cause a collision. Thus, do not use the Parking Guidance in such situations. G Warning! Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them.

! 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 as close to the

parking space 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 warning

messages during the parking procedure (Y page 308).

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

Driving systems

311

RNever use Parking Guidance with snow

chains or an emergency spare wheel installed.

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. At speeds below 19 mph (30 km/h), you see white parking symbol ; in the instrument cluster as a status indicator. Parking Guidance only shows parking spaces on the passenger side in the default setting. Parking spaces on the driver's side are displayed as

312 Driving systems

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. If a parking space is detected, parking symbol ; changes to blue. Additionally, an arrow pointing right = or left : is shown. Parking Guidance will only detect parking spaces: Rthat are closed in at the back 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 The following instructions refer to parking in a space on the front-passenger side. To park in a space on the driver's side, mirror the instructions. 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.

Only use rear view camera if you can see and distinguish all colored guidelines shown by rear view camera on the COMAND system display. G Warning Please note that objects that do not touch the ground may appear to be further away than they actually are, for example: Rthe bumper of a vehicle parked behind you Rthe trailer drawbar Rthe ball coupling of a trailer tow hitch Rthe rear end of a truck Ra slanted post In such cases, you should not use the guide lines to judge the distance. You may misjudge the distance, which increases the risk of impacting the objects. Even if the object you approach is directly on the ground, do not approach the object any closer than the red guide line.

Guide lines ; and = show the approximate distance to the rear area. Yellow guide line ; indicates a distance of approximately 3 ft (1 m) and red guide line = indicates a distance of approximately 10 in (0.25 m). The distances only apply to objects at ground level. Blue guide line : depicts the width required for the vehicle. It is used to align the vehicle with the edge of the road, e.g. the curb.

ATTENTION ASSIST Important safety guidelines ATTENTION ASSIST helps you during long, monotonous journeys such as on highways and trunk roads. It is active in the range between 50 mph (80 km/h) and 112 mph (180 km/h). If ATTENTION ASSIST detects fatigue or increasing lapses in concentration on the part of the driver, it suggests you take a break. G Warning! The ATTENTION ASSIST is only an aid to the driver. It might not recognize fatigue or increasing inattentiveness in time or fail to recognize them at all. The system cannot substitute a rested and attentive driver. Fatigue can cause you to recognize dangers too late, to misjudge potential dangers, or to react slower. Therefore, make sure to be rested before and during your trip. Take rests early enough and regularly, especially during long trips. Failure to do so could cause you to

316 Driving systems

recognize dangers too late which could result in an accident and serious injury to you and/ or 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 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 are predominantly driving slower than 50 mph (80 km/h) or faster than 112 mph (180 km/h)

Rif you are currently operating or making a

call using COMAND

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 340). Symbol : appears in the multifunction display.

If ATTENTION ASSIST is active, it will not warn you until at least 20 minutes after your journey has begun. You then hear an

intermittent warning tone twice and the Attention Assist Time for a break? 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 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 it 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.

Night View Assist Plus Important safety notes In addition to the illumination provided by the normal headlamps, Night View Assist Plus uses infrared light to illuminate the road. A camera at the top of the windshield picks up the infrared light and displays a black-and- white image in the multifunction display. The image shown in the multifunction display corresponds to a road lit up by high-beam headlamps. This enables you to see the road's course and any obstacles in good time. If pedestrian recognition is activated, pedestrians recognized by the system are highlighted in the Night View Assist Plus display. G Warning Night View Assist Plus is only an aid designed to assist driving. It is not a substitute for attentive driving. Do not rely solely on the Night View Assist Plus display. Continue to look through the windshield. You are responsible for safety and must drive in

accordance with traffic conditions. You could otherwise put yourself and others in danger. The system may be impaired or unavailable if: Rthere is poor visibility, e.g. due to snow,

rain, fog or heavy spray.

Rthe windshield is dirty, fogged up or

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

Ryou are driving on bends, uphill gradients

Light from the headlamps of oncoming vehicles does not affect the Night View Assist Plus display in the multifunction display. This is also the case if you cannot switch on the high-beam headlamps because of oncoming traffic. G Warning! The Night View Assist Plus cannot record objects immediately in front of or next to the vehicle. When maneuvering, continue to look through the windshield. Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them.

i Infrared light is not visible to the human

eye and therefore does not glare. Night View Assist Plus can therefore remain switched on even if there is oncoming traffic.

Active Driving Assistance package General information The Active Driving Assistance package consists of DISTRONIC PLUS (Y page 293), Active Blind Spot Assist (Y page 320) and Active Lane Keeping Assist (Y page 323).

Active Blind Spot Assist Important safety guidelines Active Blind Spot Assist uses a radar sensor system to monitor the side areas of your vehicle. In addition, it uses the radar sensor system to monitor the front area. Active Blind Spot Assist provides assistance at speeds higher than about 20 mph (30 km/h). A warning lamp in the exterior mirror calls your attention to a vehicle or to certain obstacles in the area monitored. If you then indicate a turn towards that side before changing lanes, you will also receive visual and audible collision warnings. If a risk of lateral collision

is detected, corrective braking may help you avoid a collision. 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. Rthe road is narrow and winding. Active Blind Spot Assist may not detect narrow vehicles, such as motorcycles or bicycles, or 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

Driving systems

321

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.

i USA only:

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. Removing, tampering with, or altering 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 Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 342) and operational. Monitoring range Active Blind Spot Assist monitors the area up to 10 ft (3 m) behind your vehicle and directly next to your vehicle as shown in the diagram. For this purpose, Active Blind Spot Assist uses sensors in the rear bumper.

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 the edge of their lane that 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, the system may be unable to distinguish the neighboring lane from the one beyond it. For this reason, vehicles in the farther lane may be indicated, especially if the vehicles are driving in a staggered formation in different lanes. In particular, this may be the case if the vehicles are driving at the edge of their lane nearest your vehicle. Due to the nature of the system, warnings may be issued in error when driving close to crash barriers or similar solid lane borders. Two Active Blind Spot Assist sensors are integrated into the front and rear bumpers respectively. An additional sensor is located behind the cover in the radiator grill. Make sure that the bumpers are free from dirt, ice, or slush around the sensors. The rear radar sensors must not be covered, for example by cycle 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. Active Blind Spot Assist may otherwise fail to work correctly.

Information and warning display

: Yellow indicator lamp/red warning lamp When Active Blind Spot Assist is activated, indicator lamp : in the exterior mirrors lights up in yellow at speeds of up to 20 mph (30 km/h). At speeds above 20 mph (30 km/h), the indicator lamp goes out and Active Blind Spot Assist is operational. If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 20 mph (30 km/h), warning lamp : on the corresponding side lights up in red. This warning is always emitted when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 7 mph (12 km/h). The yellow indicator lamp goes out if reverse gear is engaged. Active Blind Spot Assist is then no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. G Warning Active Blind Spot Assist is not active at speeds lower than 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.

Optical and acoustic collision warning When you switch on the appropriate turn signals to change lanes, and a vehicle is detected in the side monitoring range of Active Blind Spot Assist, you receive an optical and acoustic collision warning. You then hear a double warning tone, and 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. Course-correcting brake application If Active Blind Spot Assist detects a risk of collision in the monitoring range, under certain circumstances it will brake the vehicle briefly on one side. This is designed to help you avoid a collision. This function is available in the range between 20 mph and 120 mph (30 km/h and 200 km/h). When a course-correcting brake application occurs, red warning lamp : flashes in the exterior mirror and the following message, for example, appears in the multifunction display:

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

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 to 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 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.

Either a very slight course-correcting brake application, or none at all, may occur if: Rthere are other vehicles and/or obstacles, such as crash barriers, close to the vehicle. Ra vehicle approaches you too closely at the

side.

Ryou have adopted a sporty driving style with

high cornering speeds.

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

ESP® or PRE-SAFE® Brake.

RESP® is deactivated. Ra loss of tire pressure or a defective tire has

been detected and displayed

Activating Active Blind Spot Assist X Make sure that the radar sensor system (Y page 342) and Active Blind Spot Assist are activated in the on-board computer. X Turn the SmartKey to position 2 in the

ignition lock. Warning lamps : light up red in the exterior mirrors for approximately 1.5
seconds and then turn yellow.

Active Lane Keeping Assist Important safety guidelines Active Lane Keeping Assist monitors the area in front of your vehicle by means of a camera at the top of the windshield. Active Lane Keeping Assist detects lane markings on the road and warns you before you leave your lane unintentionally. If you do not react to the warning, a lane-correcting application of the brakes can bring the vehicle back into the original lane.

: Active Lane Keeping Assist camera If you select km on the on-board computer in the Display unit Speed-/odometer: (Y page 341) function, Active Lane Keeping Assist is activated starting at a speed of 60 km/h. If the mph display unit is selected, the assistance range begins at 40 mph. G Warning Active 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: Rseveral or no lane markings for a single lane

are present.

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.
