Towing a trailer Notes on towing a trailer Important safety notes G WARNING If you install a ball coupling other than the one delivered with the vehicle, the trailer tow hitch and the rear axle may be overloaded. This applies especially if the ball coupling in question is longer or angled differently. This could seriously impair the driving characteristics and the trailer can come loose. There is a risk of an accident. Only install the ball coupling delivered with the vehicle or a ball coupling that is designed to meet your trailer towing requirements. Do not modify the ball coupling or the trailer tow hitch. G WARNING If the ball coupling is not installed correctly or not secured with the bolt provided and the corresponding spring cotter, the trailer may come loose. There is a risk of an accident. Always install and secure the ball coupling as described. Before every journey, ensure that the ball coupling is secured with the bolt and the corresponding spring cotter. G WARNING If you rest your foot on the brake pedal while driving, the braking system can overheat. This increases the stopping distance and can even

cause the braking system to fail. There is a risk of an accident. Never use the brake pedal as a footrest. Never depress the brake pedal and the accelerator pedal at the same time. G WARNING When the vehicle/trailer combination begins to lurch, you could lose control of it. The vehicle/trailer combination could even rollover. There is a risk of an accident. On no account should you attempt to straighten up the vehicle/trailer combination by increasing the speed. Reduce vehicle speed and do not countersteer. Apply the brake as necessary.

! Depressing the brake pedal constantly

results in excessive and premature wear to the brake pads.

Please observe the manufacturer's operating instructions for the trailer coupling if a detachable trailer coupling is used. 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, 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 manufacturer on the vehicle identification

254 Towing a trailer

plates and those for the towing vehicle under "Technical data" (Y page 455). When towing a trailer, your vehicle's handling characteristics will be different in comparison with when driving without a trailer. The vehicle/trailer combination: Ris heavier Ris restricted in its acceleration and

gradient-climbing capability

Rhas an increased braking distance Ris affected more by strong crosswinds Rdemands more sensitive steering Rhas a larger turning radius This could impair the handling characteristics. When towing a trailer, always adjust your speed to the current road and weather conditions. Do not exceed the maximum permissible speed for your vehicle/trailer combination.

General notes RDo not exceed the legally prescribed

maximum speed for vehicle/trailer combinations in the relevant country. This lowers the risk of an accident.

ROnly install an approved trailer coupling on

your vehicle. Further information on availability and on installation is available from any authorized Mercedes-Benz Center.

RThe bumpers of your vehicle are not

suitable for installing detachable trailer couplings.

RDo not install hired trailer couplings or

other detachable trailer couplings on the bumpers of your vehicle.

RIf you no longer need the ball coupling, remove it from the ball coupling recess. This will reduce the risk of damage to the ball coupling.

i When towing a trailer, set the tire

pressure on the rear axle of the towing

vehicle for a maximum load; see the tire pressure table in the fuel filler flap (Y page 419).

You will find installation dimensions and loads in the "Technical data" section (Y page 454). The maximum noseweight of the trailer drawbar on the ball coupling is 575 lbs(261 kg) for all models (except the model ML 350 BlueEFFICIENCY). The maximum noseweight of the trailer drawbar on the ball coupling is 529 lbs (240 kg) for the model ML 350 BlueEFFICIENCY. The actual noseweight may not be higher than the value which is given. The value can be found on the trailer tow hitch or trailer identification plates. The lowest weight applies. Please note that when towing a trailer, PARKTRONIC (Y page 213) and Blind Spot Assist (Y page 233) are only available with limitations, or not at all. i On vehicles without level control, the

height of the ball coupling will alter according to the load placed on the vehicle. If necessary, use a trailer with a height- adjustable drawbar.

Driving tips i Observe the information on ESP® trailer

stabilization (Y page 72) and on pulling away with a trailer (Y page 160).

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 maximum permissible speed is. Observe the legally prescribed maximum speed in the relevant country. For certain Mercedes-Benz vehicles, the maximum permissible rear axle load is increased when towing a trailer. See "Technical data" to find out whether this applies to your vehicle (Y page 455). If you

Towing a trailer

255

utilize any of the added maximum rear axle load when towing a trailer, the vehicle/trailer combination may not exceed a maximum speed of 60 mph (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 60 mph (100 km/h). When towing a trailer, your vehicle's handling characteristics will be different in comparison with when driving without a trailer. 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 or DISTRONIC PLUS.

This will use the braking effect of the engine, so that less braking will be required to maintain the 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 counter-steer. X Brake if necessary. RMaintain a greater distance from the

vehicle 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, decreases with increasing altitude.

Installing the ball coupling G WARNING If the ball coupling is not installed and secured correctly it can become detached while the vehicle is in motion and fall onto the road. There is a risk of accident and injury. Always install and secure the ball coupling as described. Before every journey, ensure that the ball coupling is secured with the bolt and the corresponding spring cotter. G WARNING If the ball coupling is not installed correctly or not secured with the bolt provided and the corresponding spring cotter, the trailer may come loose. There is a risk of an accident. Always install and secure the ball coupling as described. Before every journey, ensure that the ball coupling is secured with the bolt and the corresponding spring cotter. G WARNING If the ball coupling is not installed and secured correctly the trailer may come loose. There is a risk of an accident. Install and secure the ball coupling as described in the ball coupling installation instructions. Make sure that the ball coupling is installed and secured correctly before every journey.

If the ball coupling cannot be correctly mounted, remove the ball coupling. Under these circumstances, the ball coupling must not be used for trailer towing. If the ball coupling cannot be locked and the key cannot be removed, remove the ball coupling and clean it. If the ball coupling can still not be installed (locked) after it has been cleaned, remove the ball coupling. The trailer tow hitch must then not be used to tow a trailer, as safe operation cannot be guaranteed. Have the entire trailer tow hitch checked at a qualified specialist workshop.

Coupling up a trailer ! Do not connect the trailer's brake system (if featured) to the hydraulic brake system of the towing vehicle, as the latter is equipped with an anti-lock brake system. Doing so will result in a loss of function of the brake systems of both the vehicle and the trailer.

X Make sure that the automatic transmission

is set to position P.

X Apply the vehicle's electric parking brake. X Start the engine. X Vehicles with the AIRMATIC package:

select highway level.

X Vehicles with ADS: set ADS to AUTO or

COMF.

X Switch off the engine. X Close all doors and the tailgate. X Couple up the trailer. X Establish all electrical connections. X Check that the trailer lighting system is

working.

i Vehicles with the AIRMATIC package: with a trailer attached, the vehicle will always remain at highway level. When coupling up a trailer, please observe the following: RUnless highway level has been set

manually, the vehicle is automatically lowered to highway level. This is the case if a speed of 5 mph (8 km/h) is reached.

RHigh-speed level is not available. These restrictions apply to all accessories powered through a connection to the trailer power socket of your vehicle, e.g. a bicycle carrier.

Observe the maximum permissible trailer dimensions (width and length). Most U.S. states and all Canadian provinces require by law: RSafety chains between the towing vehicle and the trailer. The chains should be cross- wound under the trailer drawbar. They must

Towing a trailer

257

be fastened to the vehicle's trailer coupling, not to the bumper or the axle. Leave enough play in the chains to make tight cornering possible.

RA separate brake system for certain types

of trailer.

RA safety switch for braked trailers. Check the specific legal requirements applicable to your state. If the trailer detaches from the towing vehicle, the safety switch applies the trailer's brakes.

Towing a trailer There are numerous legal requirements concerning the towing of a trailer, e.g. speed restrictions. Make sure that your vehicle/ trailer combination complies with the local requirements not only in your area of residence but also at any location to which you are traveling. The police and local authorities can provide reliable information. Please observe the following when towing a trailer: RTo acquaint yourself with driving with a trailer and with the resulting changes to handling, you should practice cornering, stopping and backing up in a traffic-free location.

RBefore driving, check:

- Trailer tow hitch - Safety switch for braked trailers - Safety chains - Electrical connections - Lights

the wheels

RAdjust the exterior mirrors to provide an

unobstructed view of the rear section of the trailer.

RIf the trailer features electronically

controlled brakes, pull away the vehicle/ trailer combination carefully, manually

258 Towing a trailer

brake using the brake controller, and check the brakes for correct function.

RSecure any objects on the trailer to prevent the cargo from slipping when the vehicle is in motion.

RIf you couple up a trailer, regularly check the cargo for secure fastening and make sure that the trailer lamps and (if applicable) the trailer brakes are functioning correctly.

RBear in mind that the handling will be less

stable when towing a trailer than when driving without one. Avoid sudden steering movements.

RThe vehicle/trailer combination is heavier, accelerates more slowly, has a decreased gradient climbing capability and a longer braking distance. It is more susceptible to side winds and requires more careful steering.

RIf possible, avoid abrupt braking. Depress the brake pedal moderately at first, so that the trailer can activate its own brakes. Then increase the pressure on the brake pedal. RIf the automatic transmission continues to

shift back and forth between two gears when driving up or downhill, restrict the shift range. Select shift range 4, 3, 2, or 1. A lower gear and lower speed reduce the risk of engine failure.

RWhen driving downhill, shift to a lower gear

to utilize the engine's braking effect. Avoid continuous brake application as this may overheat the vehicle brakes and, if installed, the trailer brakes.

RIf the coolant temperature increases

dramatically while the air-conditioning system is switched on, switch off the air- conditioning system. Coolant heat can additionally be dissipated by opening the windows and by setting the

blower fan and the interior temperature to maximum.

RWhen overtaking, pay particular attention

to the extended length of your vehicle/ trailer combination. Due to the length of your vehicle/trailer combination, you will have to travel an additional distance beyond the vehicle you are overtaking before returning to the previous lane.

Decoupling a trailer G WARNING If you uncouple a trailer with the overrun brake engaged, you could trap your hand between the vehicle and the trailer drawbar. There is a risk of injury. Do not uncouple a trailer if the overrun brake is engaged. G WARNING Vehicles with level control: The vehicle is lowered as soon as you disconnect the trailer cable. This could result in your limbs or those of other people that are between the vehicle body and tires or underneath the vehicle being trapped. There is a risk of injury. Make sure that nobody is in the immediate vicinity of the wheel housings or under the vehicle when you disconnect the trailer cable.

! Do not disconnect a trailer with an

engaged overrun brake. Otherwise, your vehicle could be damaged by the rebounding of the overrun brake.

X Make sure that the automatic transmission

is set to position P.

X Apply the vehicle's electric parking brake. X Start the engine. X Close all doors and the tailgate. X Apply the trailer's parking brake.

Permissible trailer loads and drawbar loads Weight specifications Maximum permissible gross vehicle weight rating The gross trailer weight is calculated by adding the weight of the trailer to the weight of the load and equipment on the trailer. Permissible gross weight (all models except the ML 350 BlueEFFICIENCY): 7,198 lbs (3,265 kg). Permissible gross weight (ML 350 BlueEFFICIENCY): 6,613 lbs (3,000 kg). Permissible noseweight The maximum permissible trailer drawbar noseweight is the maximum weight with which the trailer drawbar can be loaded. All models (except the ML 350 BlueEFFICIENCY: 575 lbs (261 kg). ML 350 BlueEFFICIENCY: 529 lbs (240 kg). Limit for Mercedes-Benz-approved trailer couplings.

Loading a trailer RWhen loading the trailer, make sure that

neither the permissible gross weight of the trailer nor the gross vehicle weight is exceeded. The permissible gross vehicle weight is indicated on the identification plate on the B-pillar on the driver's side of the vehicle. You can find the maximum permissible values on the type plates of your vehicle and the trailer. When calculating how much weight the vehicle and trailer may carry,

pay attention to the respective lowest values.

RThe trailer drawbar load on the ball coupling must be added to the rear axle load to avoid exceeding the permissible gross axle weight. The permissible gross vehicle weight is indicated on the identification plate on the B-pillar on the driver's side of the vehicle.

i Mercedes-Benz recommends a trailer

load where the trailer drawbar noseweight accounts for 8% to 15% of the trailer's permissible gross weight.

i The weight of additional accessories,

passengers, and cargo reduces the permissible trailer load and drawbar load for your vehicle.

Checking the vehicle and trailer weight RTo check that the weights of the towing vehicle and the trailer comply with the maximum permissible values, have the vehicle/trailer combination (including the driver, passengers, and cargo with a fully laden trailer) weighed on a calibrated weighbridge.

RCheck the gross axle weight rating of the front and rear axles, the gross weight of the trailer and trailer drawbar load.

Removing the ball coupling X Remove the spring cotter. X Remove the bolt from the ball coupling

recess.

X Remove the ball coupling from the ball

coupling recess.

X Clean the ball coupling if it is dirty. Information on cleaning and care of the trailer tow hitch can be found at (Y page 374).
