ATTENTION ASSIST Important safety notes G WARNING ATTENTION ASSIST is only an aid and may detect your tiredness or lapses in concentra- tion too late or not at all. It is not a substitute for a well rested and attentive driver. Fatigue may cause you to recognise hazard- ous situations too late, misjudge a situation or react slower. For this reason, make sure you feel rested before you begin driving and during your journey. Always take breaks in good time and regularly, especially during long journeys. Otherwise, you may fail to rec- ognise dangers in time, cause an accident and injure yourself and others.
ATTENTION ASSIST helps you during long, monotonous journeys such as on motorways and trunk roads. It is active in the 80 km/h to 180 km/h range. If ATTENTION ASSIST detects typical indica- tors of fatigue or increasing lapses in con- centration on the part of the driver, it sug- gests taking a break. 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
Rjourney-related parameters, e.g. time of
day, length of journey
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 sur-
face 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 80 km/h or faster than 180 km/h

General notes
In addition to the illumination provided by the normal headlamps, Night View Assist Plus uses infrared light to illuminate the road. Night View Assist Plus camera : picks up the infrared light and displays a monochrome image in COMAND. The image displayed in COMAND corresponds to a road lit up by main-beam headlamps. This enables you to see the road's course and any obstacles in good time. When pedestrian recognition is active, pedestrians recognised by the system are highlighted in the Night View Assist Plus display. Light from the headlamps of oncoming vehi- cles does not affect the Night View Assist Plus display in the multifunction display. This is also the case if you cannot switch on the main-beam headlamps due to oncoming traf- fic. i Infrared light is not visible to the human eye and therefore does not dazzle. Night View Assist Plus can therefore remain switched on even if there is oncoming traf- fic.
Activating Night View Assist Plus Activation conditions You can only activate Night View Assist Plus if: Rthe key is in position 2 in the ignition lock. Rit is dark.

Blind Spot Assist Important safety notes G WARNING Blind Spot Assist is only an aid designed to assist driving. It may fail to detect some vehi- cles and is no substitute for attentive driving. Blind Spot Assist cannot detect road and traf- fic conditions. It may fail to detect narrow vehicles, such as motorcycles or bicycles, or only detect them too late. Monitoring may be affected by dirty sensors, strong spray or poor visibility caused by snow, rain or mist, for example. In this case, vehicles are detected late or not at all.
Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others. G WARNING Blind Spot Assist is not active at speeds below 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 recognise dangers in time, cause an accident and injure yourself and others.
General 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 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. For monitoring, Active Blind Spot Assist uses sensors in the rear bumper. For Blind Spot Assist to assist you when driv- ing, the radar sensor system must be activa- ted (Y page 283) and operational. The radar sensor system is switched off auto- matically in the vicinity of radio telescope facilities (Y page 433). Monitoring range of the sensors 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 pos- sible to monitor the complete width of the neighbouring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation in different lanes. This may be the case if vehi- cles 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 recognise dangers in time, cause an accident and injure yourself and others.
Blind Spot Assist monitors the area up to 3.0 m behind your vehicle and directly next to your vehicle, as shown in the diagram. 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 at the edge of their lane nearest your vehicle. Due to the nature of the system: Rwarnings may be issued in error when driv- ing close to crash barriers or similar solid lane borders.
Rwarnings may be interrupted when driving
alongside long vehicles, for example lor- ries, for a prolonged time.
The two radar sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free of dirt, ice or slush in the vicinity of the sensors. The sensors must not be covered, for exam- ple by cycle racks or overhanging loads. Fol- lowing a severe impact or in the event of dam- age to the bumpers, have the function of the 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 If Blind Spot Assist is switched on, indicator lamp : in the exterior mirrors lights up yel- low up to a speed of 30 km/h. At speeds above 30 km/h, the indicator lamp goes out and Blind Spot Assist is operational.
240 Driving systems
If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 30 km/h, warning lamp : on the corre- sponding side lights up red. This warning always occurs 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 12 km/h. The yellow indicator lamp goes out if reverse gear is engaged. Blind Spot Assist is then deactivated. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the corresponding 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 283) and Blind Spot Assist (Y page 279) are activated in the on-board computer.
X Turn the key to position 2 in the ignition
lock. Warning lamps : in the exterior mirrors light up red for approximately 1.5 seconds and then turn yellow.
Towing a trailer If you attach a trailer, make sure that you have correctly established the electrical connec- tion. This can be accomplished by checking the trailer lighting. Blind Spot Assist is then deactivated. The indicator lamp in the exte- rior mirrors lights up yellow, and the Blind Spot Assist currently unavailable See Owner's Manual message appears in the multifunction display. i You can deactivate the indicator lamps in
the exterior mirrors. To do so, switch off Blind Spot Assist if: Rthe key is in position 2 in the ignition
lock.
Rthe engine is not running. Rthe electrical connection to the trailer

Lane Keeping Assist Important safety notes G WARNING Lane Keeping Assist does not keep your vehi- cle 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 func- tion if: Rthere is poor visibility, e.g. due to insuffi-
cient 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 windscreen is dirty, misted up or cov- ered, 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 recognise dangers in time, cause an accident and injure yourself and oth- ers.

rain, fog or spray.
Rthe rear and/or front sensors are dirty. Active Blind Spot Assist may not detect nar- row vehicles, such as motorcycles or bicycles, or only detect them too late. It cannot detect vehicles which are overtaken at a small dis- tance 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 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 recognise dangers in time, cause an accident and injure yourself and oth- ers.
The radar sensor system is automatically deactivated near radio telescope facilities (Y page 433). For Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 283) and operational. General notes Active Blind Spot Assist uses a radar sensor system to monitor the area to the sides of your vehicle which are behind 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 cor- responding turn signal to change lane, you will also receive an optical and audible warn- ing. If a risk of lateral collision is detected, corrective braking may help you avoid a col- lision. To support the course-correcting brake application, Active Blind Spot Assist uses the forward-facing radar sensor system. The free space in the direction of travel is then evalu- ated. Active Blind Spot Assist supports you from a speed of approximately 30 km/h. Monitoring range 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 audi- ble 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 pos- sible to monitor the complete width of the neighbouring 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

rear sensors must not be covered, e.g. 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. Active Blind Spot Assist may oth- erwise no longer work properly. Indicator and warning display G WARNING Active Blind Spot Assist is not active at speeds below 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 recognise dangers in time and cause an acci- dent and injure yourself and others.
Active Blind Spot Assist monitors the area up to 3.0 m behind your vehicle and directly next to your vehicle, as shown in the diagram. For this purpose, Active Blind Spot Assist uses radar sensors in the rear bumper. 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 at the inner edge of your lane. Due to the nature of the system: Rwarnings may be issued in error when driv- ing close to crash barriers or similar solid lane borders.
Rwarnings may be interrupted when driving
alongside particularly long vehicles, for example lorries, for a prolonged time.
The Active Blind Spot Assist radar sensors are integrated into the front and rear bumpers and behind a cover in the radiator grille. Make sure that the bumpers and the cover in the radiator grille are free of dirt, ice or slush. The
: Yellow indicator lamp/red warning lamp If Active Blind Spot Assist is switched on, indicator lamps : in the exterior mirrors light up yellow up to a speed of 30 km/h. At speeds above 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 approximately 30 km/h, warning lamp : on the corresponding side lights up red. This warning always occurs 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 12 km/h.

Otherwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others.
When you switch on the turn signals to change lanes and a vehicle is detected in the side monitoring range, you receive a visual 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 flash- ing of red warning lamp :. There are no fur- ther warning tones. Course-correcting brake application G WARNING Active Blind Spot Assist is only an aid designed to assist driving. It is not a substitute for attentive driving. Automatic braking by the system may not always be sufficient to avoid a collision. In such cases, you need to steer, brake or accelerate yourself. In very rare cases, the system may detect a risk of collision where there is none and brake in error near crash barriers or similar road boundaries. Active Blind Spot Assist cannot detect all traffic situations and road users. Ensure at all times that there is sufficient lat- eral distance between you and other road users or obstacles. You can, for example, countersteer gently or depress the accelera-
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 designed to help you avoid a col- lision.

Active Lane Keeping Assist Important safety notes 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 func- tion if: Rseveral or no lane markings for a single lane
are present.
Rthere is poor visibility, e.g. due to insuffi-
cient 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 windscreen is dirty, misted up or cov- ered, 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 substi- tute 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. Oth- erwise, you may fail to recognise dangers in time, cause an accident and injure yourself and others.
General notes
Active Lane Keeping Assist monitors the area in front of your vehicle by means of a cam- era : at the top of the windscreen. 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. If you select km on the on-board computer in the Display unit Speed-/odometer: function (Y page 280), Active Lane Keeping Assist is activated starting at a speed of 60 km/h. If the miles display unit is selected, the assistance range begins at 40 mph. Warning vibration in the steering wheel A warning may be given if 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 nec- essary and in good time if you cross the lane marking, the system recognises certain con- ditions 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 motor-
way.
Rthe system recognises solid lane markings. The warning vibration occurs later if: Rthe road has narrow lanes. Ryou cut the corner on a bend. Lane-correcting brake application 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. Corrective braking may not always be sufficient to return your vehicle to its original lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane. Active Lane Keeping Assist cannot detect the current traffic situation or other road users. Ensure at all times that there is sufficient lat- eral distance between you and other road users or obstacles. In rare cases, broken lines or certain structures on the road surface may be detected by the system as solid lane mark- ings. You can, for example, countersteer gen- tly at any time to cancel inappropriate braking action, e.g. if you intentionally drive across a solid lane marking. Active Lane Keeping Assist cannot take weather conditions into account. You are responsible for the vehicle's speed, correct steering and for braking in good time. 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 recognise dangers in time, cause an accident and injure yourself and others.

If a lane-correcting brake application occurs, display : appears in the multifunction dis- play. If you leave your lane under certain circum- stances, the vehicle will brake briefly on one side. This is designed to help you bring the vehicle back into the original lane. This function is available in the range between 60 km/h and 200 km/h. A lane-correcting brake application can only be made after driving over a solid, recognis- able lane marking. Before this, a warning must be emitted by means of intermittent vibration in the steering wheel. In addition, a lane with lane markings on both sides must be recognised. The brake application also slightly reduces driving speed. i A further lane-correcting brake applica- tion can only occur after your vehicle has returned to the original lane.
