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. The radar sensor system is switched off auto- matically in the vicinity of radio telescope facilities (Y page 349). For Blind Spot Assist to assist you when driv- ing, the radar sensor system must be activa- ted (Y page 204) and operational.
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.
Information in the COMAND display (example) Guide lines ; and = show the approximate distance to the rear area. Yellow guide line ; approximately 1.0 m and red guide line = approximately 0.25 m. The distances only apply to objects that are at ground level. Blue guide lines : depict the width required for the vehicle. They are used to align the vehicle with the edge of the carriageway, e.g. the kerb.
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

Indicator and warning display
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.
: 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. 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 204) and Blind Spot Assist (Y page 207) 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
has been established.
Towing a trailer Notes on towing a trailer Important safety notes G WARNING Vehicles with level control: The vehicle level can be changed inadver- tently, e.g. when changed by another person. If you are coupling up or uncoupling a trailer when this happens, you could become trap- ped. Body parts can also become trapped
between the vehicle body and tyres, or under- neath the vehicle. This poses a risk of injury. When coupling up or uncoupling, make sure that no-one: Ropens or closes the doors or tailgate Rinitiates the level control or presses the
ADS switch
Rlocks or unlocks the vehicle. G WARNING The braking system can overheat if you leave your foot on the brake pedal while driving. This increases the braking distance and could even cause the braking system to fail. There is a risk of an accident. Never use the brake pedal as a footrest. Do not simultaneously depress both the brake pedal and the accelerator pedal while driving. G WARNING You could lose control of the vehicle/trailer combination if it begins to swerve. The vehi- cle/trailer combination could even overturn. There is a risk of an accident. On no account should you attempt to straighten out the vehicle/trailer combina- tion by increasing speed. Decrease your speed and do not countersteer. Brake if nec- essary. G WARNING If you exceed the permissible noseweight while carrying a load, the carrier system could detach from the vehicle and fall on the road. There is a risk of an accident and injury. Always maintain the permissible noseweight when carrying loads. G WARNING If the ball coupling is not correctly engaged, it could detach while driving and fall on the road. There is a risk of an accident and injury. Engage the ball coupling as described.

185
G WARNING If the ball coupling is not correctly engaged, the trailer can detach. There is a risk of an accident. Always engage the ball coupling as described.
! Depressing the brake pedal constantly
results in excessive and premature wear to the brake pads.
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. 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
The applicable permissible values that must not be exceeded can be found: Rin your vehicle documents and Ron the identification plates on the trailer
tow hitch, the trailer and the vehicle
Should the values differ, then the lowest applies. You will find the values approved by the man- ufacturer on the vehicle identification plates and those for the towing vehicle under "Tech- nical data" (Y page 349). 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 This could impair the handling characteris- tics. Adapt your style of driving accordingly. Maintain a safe distance. Drive carefully. When towing a trailer, always adjust your speed to the current road and weather con- ditions. Do not exceed the maximum permis- sible speed for your vehicle/trailer combina- tion.
General notes ! Use a drawbar noseweight as close as
possible to the maximum permissible nose- weight. Do not use a noseweight of less than 50kg, otherwise the trailer may come loose. Note that the payload and the rear axle load are reduced by the actual payload.
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 315).
You will find installation dimensions and loads in the "Technical data" section (Y page 347). The maximum noseweight of the trailer draw- bar on the ball coupling is 85 kg. The actual noseweight may however not be higher than the value which is given on the trailer tow hitch or trailer identification plates. The low- est weight applies. Please note that when towing a trailer, PARK- TRONIC (Y page 177) and Blind Spot Assist (Y page 182) are only available with limita- tions, or not at all.
186 Towing a trailer
Driving tips i Observe the notes on ESP® trailer stabi-
lisation (Y page 64).
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 (Y page 349) 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.
Driving tips If the trailer swings from side to side: X Do not accelerate. X Do not countersteer. X Brake if necessary. 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.
Fitting the ball coupling (vehicles with an external spare wheel) G WARNING If the ball coupling is not correctly engaged, it could detach while driving and fall on the road. There is a risk of an accident and injury. Engage the ball coupling as described. G WARNING If the ball coupling is not correctly engaged, the trailer can detach. There is a risk of an accident. Always engage the ball coupling as described. G WARNING If you release the ball coupling or it does not engage correctly when folding in, it will swing out. Within pivoting range of the ball coupling, there is an increased risk of an accident and injury. Only release the ball coupling if the pivoting range is unobstructed. Always make sure that the ball coupling engages when folding in.

Heating Auxiliary heating departure time G WARNING Exhaust fumes are produced when the auxili- ary heating is in operation. Inhaling these exhaust fumes can be poisonous. You should therefore switch off the auxiliary heating in confined spaces without an extraction sys- tem, e.g. a garage. G WARNING When operating the auxiliary heating parts of the vehicle can get very hot. Make sure that the exhaust system does not under any cir- cumstances come into contact with easily ignitable material such as dry grass or fuels. The material could otherwise ignite and set the vehicle alight. Choose your parking spot accordingly. Operating the auxiliary heating is thus pro- hibited at filling stations or when your vehicle is being refuelled. You must therefore switch off the auxiliary heating at filling stations.
! Operating the auxiliary heating/ventila- tion draws on the vehicle battery. After you have heated or ventilated the vehicle a maximum of two times, drive for a longer distance.
This function is only available on vehicles with auxiliary heating (Y page 135). You can select a stored departure time or change a departure time using the Aux. heating departure time function. The auxiliary heating timer function calcu- lates the switch-on time according to the out- side temperature so that the vehicle is pre- heated by the departure time. When the departure time is reached, the auxiliary heat- ing continues to heat for a further five minutes and then switches off. The auxiliary heating adopts the THERMATIC or THERMOTRONIC temperature setting.
