on such a dynamometer, please consult a qualified workshop. You could otherwise damage the drive train or the brake system. 4MATIC ensures that all four wheels are per- manently driven. Together with ESP® and 4ETS, it improves the traction of your vehicle whenever a drive wheel spins due to insuffi- cient grip. i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you use winter tyres (M+S tyres), with snow chains if necessary.

DSR (Downhill Speed Regulation) Important safety notes G WARNING DSR is only an aid designed to assist you when driving downhill. You are responsible for keep- ing control of the vehicle and for assessing whether the downhill gradient can be man- aged. When activating DSR the vehicle may brake suddenly due to DSR intervening. This is dependent on the downhill gradient and the difference between the current speed and the speed set. DSR may not always be able to keep to the set speed, depending on road sur- face and tyre conditions. You could lose con- trol of the vehicle and cause an accident. Select a set speed suitable for the prevailing conditions and when necessary, apply the brakes manually. G WARNING If you depress the accelerator pedal with DSR activated, then the set speed can be excee- ded. Drive downhill with special care and always keep in mind that DSR brakes the vehi- cle as soon as you remove your foot from the accelerator pedal. The vehicle may brake sud- denly due to DSR intervening, depending on the downhill gradient and the difference
between the current speed and the set speed. You could lose control of the vehicle and cause an accident.
DSR assists you when driving downhill. It keeps the speed of travel at the speed set on the on-board computer. The steeper the downhill gradient, the greater the DSR brak- ing effect on the vehicle. When driving on flat stretches of road or on an uphill gradient, the DSR braking effect is minimal or non-existent. DSR controls the set speed when it is active and the automatic transmission is in the D, R or N position. By accelerating or braking, you can always drive at a higher or a lower speed than that set on the on-board com- puter. Further information about "Driving off-road" (Y page 188). Activating DSR

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. 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.
258 Towing a trailer
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, which must not be exceeded, can be found: Rin the vehicle documents Ron the identification plates of the trailer tow
hitch, the trailer and the vehicle
If the values differ, the lowest value 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 433). 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 Check the tyre pressures when towing a trailer. You will find the values in the tyre pressure table in the fuel filler flap of the vehicle (Y page 399).
You will find installation dimensions and loads in the "Technical data" section (Y page 432). The maximum permissible trailer drawbar noseweight on the ball coupling is 140 kg. However, the actual noseweight must not exceed the value given on the trailer tow hitch or trailer identification plates. The lowest weight applies. Please note that when towing a trailer, PARK- TRONIC (Y page 216) and Blind Spot Assist (Y page 238) are only available with limita- tions, or not at all.
Driving tips i Observe the information on ESP® trailer
stabilisation (Y page 67) and on pulling away with a trailer. (Y page 162).
Vehicles with the ON&OFFROAD pack- age: select the trailer program (Y page 250) with the off-road program selector wheel in the centre console. 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. See "Technical data" to find out whether this applies to your vehicle (Y page 433). 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
Towing a trailer
259
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.
Folding out the ball coupling 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.
! AMG vehicles and vehicles with AMG bodystyling: remove the cover below the bumper before you fold out the ball cou- pling. Otherwise, the ball coupling, the cover and the bumper could be damaged. Before you can tow a trailer with your vehicle, you must fold out the ball coupling. X Make sure that the vehicle is stationary.

X Open the tailgate.
i If you have coupled a trailer, the vehicle
will remain at highway level. The vehicle automatically lowers to high- way level if you drive faster than 30km/h with a trailer. The vehicle is not lowered to high-speed level even if you are travelling at higher speeds. This also applies when using accessories that are plugged into the socket of the trailer tow hitch (e.g. a bicycle rack).
Uncoupling a trailer Important safety notes G WARNING If you uncouple a trailer with an engaged over- run brake, you could trap your hand between the vehicle and the trailer drawbar. This poses a risk of injury. Do not uncouple a trailer with an engaged overrun brake. G WARNING Vehicles with level control: If you disconnect the trailer cable, the vehicle is lowered. This can cause you or others to become trapped between the vehicle body and tyres, or underneath the vehicle. This poses a risk of injury. Make sure that no-one is in the immediate vicinity of the wheel arch or underneath the vehicle when disconnecting the trailer cable.
! Do not disconnect a trailer with an
