• Do not exceed the legally prescribed maximum speed for vehicle/trailer combinations in the relevant country. This lowers the risk of an accident.
• Only install an approved trailer coupling on your vehicle.
  Further information on availability and on installation is available from any authorized Mercedes-Benz Center.
• The bumpers of your vehicle are not suitable for installing detachable trailer couplings.
• Do not install hired trailer couplings or other detachable trailer couplings on the bumpers of your vehicle.
• To reduce the risk of damage to the ball coupling, remove it from the ball coupling recess when not in use.

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 ().

You will find installation dimensions and loads in the "Technical data" section ().

The maximum noseweight of the trailer drawbar on the ball coupling is20. However, the actual noseweight must not exceed the value given on the trailer tow hitch or trailer identification plates. The lowest weight applies.

Use a drawbar noseweight as close as possible to the maximum permissible noseweight. Do not use a noseweight that is under the minimum permissible noseweight; the trailer may otherwise come loose. Missing values were not available at time of going to print. Note that the payload and the rear axle load are reduced by the actual payload.

Please note that when towing a trailer, PARKTRONIC () is only available with limitations, or not at all.

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 heightadjustable drawbar.
