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 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 342). 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: 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 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.

Night View Assist Plus with spotlight function Important safety notes In addition to the illumination provided by the normal headlamps, Night View Assist Plus uses infrared light to illuminate the road. The Night View Assist Plus camera picks up the infrared light and shows 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. The spotlight function also illuminates individual detected pedestrians with a spotlight that flashes four times in quick succession. After this targeted illumination, the headlamps return to the original driving position again. 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

or downhill 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

Driving systems

317

high-beam headlamps due to 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.

: Night View Assist Plus camera

Pedestrian recognition G WARNING Pedestrian recognition may be impaired or inoperative if: Rpedestrians are partially or entirely

obscured by objects, e.g. parked vehicles. Rthe silhouette of the pedestrian in the Night

View Assist Plus display is incomplete or interrupted, e.g. by powerful light reflections.

Rpedestrians do not contrast with the

surroundings.

Rpedestrians are not standing upright, for example, if they are sitting, crouching or lying down.

318 Driving systems

i Animals are not recognized by pedestrian

recognition.

Night View Assist Plus is able to recognize pedestrians by typical characteristics, e.g. a silhouette in the shape of a person. Pedestrian recognition is then switched on automatically if: RNight View Assist Plus is activated. Ryou are driving faster than 6 mph

(10 km/h).

Rthe surroundings are dark, e.g. when driving outside built-up areas without street lighting.

If pedestrian recognition is enabled, the active pedestrian recognition symbol (Y page 319) appears in the multifunction display. If a pedestrian is now recognized, they are framed and thereby highlighted. If the pedestrian recognition system has brought a pedestrian to your attention, look through the windshield to evaluate the situation. The actual distance to objects and pedestrians cannot be gauged accurately by looking at a screen. It may be the case that objects are highlighted as well as pedestrians. Spotlight function Pedestrian recognition with spotlight function is activated automatically if: RNight View Assist Plus with spotlight

function is activated.

Ryou are driving faster than 28 mph

(45 km/h).

Rthe surroundings are dark, e.g. when driving outside built-up areas without street lighting.

Only one pedestrian or one object can be illuminated with the spotlight at any one time. The spotlight function will not function if: Rpedestrians or objects cannot be recognized due to fast cornering.

Rpedestrians or objects are on the driver's

side of the vehicle.

If you switch to symmetrical low beam (Y page 244), pedestrians or objects on the front-passenger side of the vehicle will not be recognized instead.

It may be the case that pedestrians and other objects are inadvertently illuminated.

Active Driving Assistance package General notes The Active Driving Assistance package consists of DISTRONIC PLUS (Y page 292), Active Blind Spot Assist (Y page 321) and Active Lane Keeping Assist (Y page 324).

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

322 Driving systems

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.

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. 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 Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 344) 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.

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. 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 there are vehicles driving at the inner edge of their lanes.

Driving systems

323

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.

Two Active Blind Spot Assist radar sensors are integrated into the front and rear bumpers respectively. An additional radar sensor is located behind the cover in the radiator grill. Make sure that the sensor areas on the bumpers and the sensor cover in the radiator grill are free of dirt, ice and slush. The rear sensors must not be covered, for example by cycle racks or overhanging cargo. 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. Blind Spot Assist may otherwise not work properly. Indicator and warning display

: Yellow indicator lamp/red warning lamp When Active 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 Active 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, Active Blind Spot Assist is 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.

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

324 Driving systems

exterior mirror and the following is shown in the multifunction display, for example:

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 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.

Switching on Active Blind Spot Assist X Make sure that the radar sensor system (Y page 344) and Active Blind Spot Assist (Y page 343) 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 notes 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 have selected the Display Unit Speed-/Odometer(Y page 344) function in the on-board computer and select km as the unit of measurement, Active Lane Keeping

Driving systems

325

Assist is active from speeds 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.

Rthe windshield is dirty, fogged up or

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

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. Active 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.

Warning vibration in the steering wheel A warning can be given when a front wheel passes over a lane marking. You will be warned 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.

Lane-correcting brake application If you leave your lane under certain circumstances the vehicle will brake briefly on one side. This is meant to assist you in bringing the vehicle back to the original lane. This function is available in the range between 40 mph and 120 mph (60 km/h to 200 km/h). A lane-correcting brake application can only be made after driving over a solid, recognizable lane marking. Before this, a warning must be given by means of intermittent vibration in the steering wheel. In addition, a lane with lane markings on both sides must be recognized. The brake

326 Driving systems

application also slightly reduces vehicle speed. If a lane-correcting brake application occurs, the following, for example, appears in the multifunction display:

i A further lane-correcting brake

application can only occur after your vehicle has returned to the original lane. G WARNING Active Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the lane- correcting brake application is not sufficient to bring your vehicle back to the original lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane. Active Lane Keeping Assist does not detect road and traffic conditions. Always make sure that there is sufficient distance to the side for other traffic or obstacles. In rare cases, unclear markings or particular structures on the roadway can be recognized as solid lane markings. An inappropriate brake application, e.g. after intentionally driving over a solid lane marking, may be interrupted at any time by steering slightly in the opposite direction. Active Lane Keeping Assist cannot take weather conditions into account. You are responsible for the 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.

No lane-correcting brake application occurs if: Ryou clearly and actively steer, brake or

accelerate.

Ryou cut the corner on a sharp bend. Ryou switch on the turn signals. Ra driving safety system intervenes, e.g. ESP®, PRE-SAFE® Brake or Active Blind Spot Assist.

Ryou have adopted a sporty driving style with

high cornering speeds or high rates of acceleration.

RESP® is switched off. Rthe transmission is not in position D. Ra loss of tire pressure or a defective tire has

been detected and displayed.

Active Lane Keeping Assist does not detect traffic situations or road users. An inappropriate brake application may be interrupted at any time if you: Rsteer slightly in the opposite direction. Ruse a turn signal. Rclearly brake or accelerate. A lane-correcting brake application is interrupted automatically if: Ra driving safety system intervenes, e.g. ESP®, PRE-SAFE® Brake or Active Blind Spot Assist.

Bring the vehicle to an authorized Mercedes-Benz Center to address the malfunction and warning messages.

Displays and operation Coolant temperature display G WARNING Driving when your engine is overheated can cause some fluids which may have leaked into the engine compartment to catch fire. You could be seriously burned. Steam from an overheated engine can cause serious burns which can occur just by opening the engine hood. Stay away from the engine if you see or hear steam coming from it. Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of the vehicle and do not stand near the vehicle until the engine has cooled down.

The coolant temperature gauge is in the instrument cluster on the left-hand side. Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 248 ‡ (120 †).

Displays and operation 331

! If the coolant temperature is too high a

display message is shown. If the coolant temperature rises above 248 ‡(120 †), do not drive any further as this could damage the engine.

Tachometer The red band in the tachometer indicates the engine's overrevving range. ! Do not drive in the overrevving range, as

this could damage the engine.

The fuel supply is interrupted to protect the engine when the red band is reached.

Outside temperature display The outside temperature display is in the multifunction display (Y page 332). G WARNING The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges.

Changes in the outside temperature are displayed after a short delay.

Operating the on-board computer The on-board computer is activated as soon as you turn the SmartKey to position 2 in the ignition lock. You can control the multifunction display and the settings in the on-board computer using the buttons on the multifunction steering wheel.
