Towing a trailer
When you attach a trailer, make sure you havecorrectly established the electrical connection.
This can be accomplished by checking the trailerlighting.
Towing a trailer
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. 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.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
You will find the values approved by the manu-facturer on the vehicle identification plates andthose for the towing vehicle under "Technicaldata" (Ypage 364).
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi-
cle/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.
!If you have a trailer tow hitch retrofitted,changes to the engine cooling system may benecessary, depending on the vehicle type.
If you have a trailer tow hitch retrofitted,observe the anchorage points on the chassisframe.
The installation of a trailer tow hitch is only per-missible if a towing weight is specified in yourvehicle documents. If this is not the case, thenthe vehicle is not approved for the towing of atrailer.

For more information, please contact a qualifiedspecialist workshop.
Please observe the manufacturer's operatinginstructions for the trailer coupling if a detach-able trailer coupling is used.
Couple and uncouple the trailer carefully. If youdo not couple the trailer to the towing vehiclecorrectly, the trailer could become detached.
Make sure that the following values are notexceeded:
Rthe permissible trailer drawbar noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towingvehicle
Rthe maximum permissible gross vehicleweight of both the towing vehicle and thetrailer
The applicable permissible values, which mustnot be exceeded, can be found:
Rin the vehicle documents
Ron the type plate for the trailer
Ron the vehicle identification plate
If the values differ, the lowest value applies.
When towing a trailer, your vehicle's handlingcharacteristics will be different in comparisonwith 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 circle
This could impair the handling characteristics.
When towing a trailer, always adjust your speedto the current road and weather conditions. Donot exceed the maximum permissible speed foryour vehicle/trailer combination.
Notes on towing a trailer
General notes
RDo not exceed the maximum permissiblespeed for vehicle/trailer combinations in therelevant country.
This lowers the risk of an accident.
ROnly install an approved trailer coupling onyour vehicle.
Further information on availability and oninstallation is available from any authorizedMercedes-Benz Center.
RThe bumpers of your vehicle are not suitablefor installing detachable trailer couplings.
RDo not install hired trailer couplings or otherdetachable trailer couplings on the bumpersof your vehicle.
RIf you no longer need the ball coupling,remove it from the ball coupling recess. Thiswill reduce the risk of damage to the ball cou-pling.
When towing a trailer, set the tire pressure onthe rear axle of the towing vehicle for a maxi-mum load; see the tire pressure table in the fuelfiller flap (Ypage 348).
Please note that when towing a trailer, the fol-lowing driving systems have limited availabilityor are not available at all:
RPARKTRONIC (Ypage 179)
RBlind Spot Assist (Ypage 193)
RActive Lane Keeping Assist (Ypage 200)
On vehicles without level control, the height ofthe ball coupling will alter according to the loadplaced on the vehicle. If necessary, use a trailerwith a height-adjustable drawbar.
You will find permissible trailer loads under"Technical data" (Ypage 364).
Driving tips
Observe the information on ESP®trailer stabili-zation (Ypage 71) and on pulling away with atrailer (Ypage 135).
The maximum permissible speed for vehicle/trailer combinations depends on the type oftrailer. Before beginning the journey, check thetrailer's documents to see what the maximumpermitted speed is. Observe the maximum per-missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-mum permissible rear axle load is increasedwhen towing a trailer. See the "Technical data"section to find out whether this applies to yourvehicle (Ypage 365). In the event of increasedrear axle load, the vehicle/trailer combinationmay not exceed a maximum speed of 60 mph(100 km/h) for reasons concerning the operat-ing permit. This also applies in countries in

You will find permissible trailer loads under"Technical data" (Ypage 364).
Loading a trailer
RWhen loading the trailer, make sure that nei-ther the permissible gross trailer weight northe permissible gross vehicle weight areexceeded. The permissible gross vehicleweight is indicated on the identification plateon the B-pillar on the driver's side of the vehi-cle.
You can find the maximum permissible valueson the type plates of your vehicle and thetrailer. When calculating how much weightthe vehicle and trailer may carry, pay atten-tion to the respective lowest values.
RThe trailer drawbar load on the ball couplingmust be added to the rear axle load to avoidexceeding the permissible gross axle weight.The permissible gross vehicle weight is indi-cated on the identification plate on the B-pil-lar on the driver's side of the vehicle.
Mercedes-Benz recommends a trailer loadwhere the trailer drawbar noseweight accountsfor 8% to 15% of the permissible gross trailerweight.
Additional accessories, passengers and loadreduce the permissible trailer load and nose-weight that your vehicle can tow.
Checking the vehicle and trailer weight
RHave the towing vehicle, including the driver,passengers and load, and completely loadedtrailer weighed on a suitable weighingmachine. This will allow you to ensure that theweights of the towing vehicle and trailer com-ply with the maximum permissible values.
RCheck the gross axle weight rating of the frontand rear axles, the gross weight of the trailerand trailer drawbar load.
