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.
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. No warning vibration occurs if: Ryou clearly and actively steer, brake, or
accelerate.

Active Blind Spot Assist Important safety notes Active Blind Spot Assist uses a radar sensor system to monitor the side areas of your vehi- cle which are behind the driver. A warning display in the exterior mirrors draws your attention to vehicles detected in the moni- tored area. If you then switch on the corre- sponding turn signal to change lane, you will also receive an optical and audible collision warning. If a risk of lateral collision is detec- ted, 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 sys- tem. Active Blind Spot Assist supports you from a speed of approximately 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 func- tion 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 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 545). For Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 408) and operational. Monitoring range Active Blind Spot Assist monitors the area up to three metres 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.
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 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.
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.
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 grille. Make sure that the sensors and the areas around them are free of dirt, ice or slush. The 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 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 : in the exterior mirrors lights up yellow at speeds of up to 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 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 12km/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 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.
Visual and acoustic collision warning If a vehicle is detected in the side monitoring range and you switch on the appropriate turn signals, you will receive a collision warning. You will 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 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. The course-correcting brake application is available in the range between 30 km/h and 200 km/h.
382 Driving systems
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:
Ryou brake or accelerate decisively. Ra driving safety system intervenes, such as
ESP® or PRE-SAFE® Brake.
RESP® is deactivated. Ra loss of tyre pressure or a defective tyre is
detected.
Activating Active Blind Spot Assist X Make sure that the radar sensor system (Y page 408) and Active Blind Spot Assist (Y page 405) are activated in the on-board computer.

Active Lane Keeping Assist Important safety notes Active Lane Keeping Assist monitors the area in front of your vehicle by means of a camera mounted 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.
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- tor pedal at any time to cancel inappropriate braking action. 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.
Either a very slight course-correcting brake application, or none at all, may occur if: Rthere are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle. Ra vehicle approaches too closely on the
side.
Ryou have adopted a sporty driving style with
high cornering speeds.

Lane-correcting brake application 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. If a lane-correcting brake application occurs, the following appears in the multifunction dis- play:
i A further lane-correcting brake applica- tion 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. 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.

Towing a trailer Notes on towing a trailer Important safety notes G WARNING When reversing the vehicle towards the trailer, make sure there is nobody between the trailer and the vehicle. Couple and uncouple the trailer carefully. If you do not couple the trailer to the towing vehicle correctly, the trailer could become detached.
Make sure that the following values are not exceeded: Rthe permissible trailer drawbar noseweight Rthe permissible trailer load Rthe permissible rear axle load of the towing
vehicle
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the trailer
You will find the applicable permissible val- ues, which must not be exceeded, in the vehi- cle documents. You will find the values approved by the man- ufacturer on the vehicle identification plates and those for the towing vehicle in the "Tech- nical data" section. G WARNING If the Check trailer hitch locking mechanism message appears in the multi- function display while the vehicle is in motion, pull over immediately and check whether the ball coupling is correctly engaged. G WARNING When towing a trailer, your vehicle's handling characteristics will be different in comparison to when driving without a trailer. The vehicle/trailer combination: Ris heavier Ris restricted in its acceleration and gradi-
ent-climbing capability
Rhas an increased braking distance Ris affected more by strong crosswinds Rdemands more sensitive steering Rhas a larger turning circle As a result, the handling characteristics may be impaired and you may lose control of the vehicle. This could lead to an accident with serious or even fatal injuries. When towing a trailer, always adjust your speed to the current road and weather con- ditions. Do not exceed the maximum permis-
386 Towing a trailer
sible speed for your vehicle/trailer combina- tion. G WARNING Never depress the brake pedal continuously while the vehicle is in motion, e.g. never cause the brakes to rub by applying constant slight pedal pressure. This causes the brake system to overheat, increases the braking distance and can lead to the brakes failing completely. G WARNING On no account should you attempt to draw the vehicle/trailer combination out by increasing speed. G WARNING If you exceed the maximum noseweight when using a carrier system on the ball coupling: Rthe carrier system may be thrown around. Rthe ball coupling and the carrier system may become detached from the vehicle.
As a result, you may injure others or cause an accident. Do not exceed the maximum noseweight. When driving with a loaded carrier system, always adjust your driving style to the prevail- ing road, traffic and weather conditions and drive particularly carefully.
You can use carrier systems, e.g. bicycle racks or load-bearing implements, on the ball coupling. The maximum noseweight of 75 kg applies when using carrier systems on the ball coupling.
General notes i When towing a trailer, set the tyre pres- sure on the rear axle of the towing vehicle for a maximum load; see the tyre pressure table in the fuel filler flap (Y page 520).
You will find installation dimensions and loads in the "Technical data" section (Y page 543).
! Use a drawbar noseweight as close as
possible to the maximum permissible nose- weight. Do not use a noseweight of less than 50 kg, as the vehicle/trailer combina- tion may otherwise become unstable. Note that the payload and the rear axle load are reduced by the actual noseweight. G WARNING If you exceed the maximum permissible nose- weight of the trailer drawbar on the ball cou- pling, the trailer, ball coupling, trailer tow hitch or vehicle could be damaged by towing the trailer. The car/trailer combination may become unstable. If the noseweight used is lower than the min- imum permissible noseweight, the vehicle/ trailer combination may become unstable. There is a risk of an accident. To avoid hazardous situations: Ryou must check the noseweight before
each journey.
Ruse a drawbar noseweight as close as pos-
sible to the maximum noseweight.
Rdo not exceed the maximum permissible
noseweight.
Rdo not use a noseweight lower than the
minimum noseweight.
The maximum permissible trailer drawbar noseweight on the ball coupling is 85 kg25. The minimum noseweight of the trailer draw- bar on the ball coupling must not fall below 50 kg. However, the actual noseweight must not exceed the value given on the trailer tow hitch identification plate. In addition, a distinction should be made between towing a trailer and using a carrier system on the ball coupling of the trailer tow hitch. Note also that the payload and the rear axle load are reduced by the actual noseweight. i On vehicles without level control, the
height of the ball coupling will alter accord-

Driving tips RMaintain a greater distance from the vehi-
cle in front than when driving without a trailer.
RAvoid braking abruptly. If possible, brake gently at first to allow the trailer to run on. Then, increase the braking force rapidly.
RThe values given for gradient-climbing
capabilities from a standstill refer to sea level. When driving in mountainous areas, note that the power output of the engine, and consequently the vehicle's gradient- climbing capability, decrease with increas- ing altitude.
If the trailer swings from side to side: X Do not accelerate. X Do not countersteer. X Brake if necessary.
Folding out the ball coupling G WARNING Vehicles with HYBRID: ensure that you read the "HYBRID" supplement. You may otherwise fail to recognise dangers.
Before you can tow a trailer with your vehicle, you must fit the ball coupling. The telescopic lever is under the cover on the left-hand side of the boot.
ing to the load placed on the vehicle. If nec- essary, use a trailer with a height-adjusta- ble drawbar.
Driving tips i Observe the notes on ESP® trailer stabi-
lisation (Y page 73).
The maximum permissible speed for vehicle/ trailer combinations depends on the type of trailer. Before beginning the journey, check the trailer's documents to see what the max- imum permitted speed is. Observe the legally prescribed maximum speed in the relevant country. For certain Mercedes-Benz vehicles, the max- imum permissible rear axle load is increased when towing a trailer. Refer to the "Technical data" section to find out whether this applies to your vehicle. If you utilise any of the added maximum rear axle load when towing a trailer, the vehicle/trailer combination may not exceed a maximum speed of 100 km/h for reasons concerning the operating permit. This also applies in countries in which the permissible maximum speed for vehicle/ trailer combinations is above 100 km/h. When towing a trailer, your vehicle's handling characteristics will be different in comparison to when driving without a trailer and it will consume more fuel. On long and steep downhill gradients, you must select shift range 1, 2 or 3 in good time. i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS- TRONIC PLUS.
This will use the braking effect of the engine, so less braking will be required to prevent the vehicle from gaining speed. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If you need additional braking, depress the brake pedal repeatedly rather than continuously.
