Try to avoid towing a loaded trailer with an unladen vehicle. If this cannot be avoided, drive extra slowly to allow for the unbalanced weight distribution.

Normally, you must not exceed 80 km/h when towing a trailer or caravan. However, if the trailer/caravan meets certain technical requirements1), you can drive at max. 100 km/h. Please observe any other regulations applicable in the country in which you are travelling.

The stability of the car and trailer is reduced with increasing speed. For this reason it is advisable not to drive at the maximum permissible top speed in unfavourable road, weather or wind conditions. This applies especially on a downhill gradient.

You should always reduce speed immediately if the trailer shows the slightest sign of swaying. Never try to stop the swaying by accelerating further.

Always brake in good time. If the trailer has an overrun brake, apply the brakes gently at first and then firmly. This will prevent the jerking that can be caused by the trailer wheels locking. Change down in good time before going down a steep hill so that you can use the engine braking effect to slow down the vehicle.

Swaying and pitching can be reduced by stabiliser aids. We recommend having stabiliser aids installed when towing trailers with a high trailer weight. They can be purchased and installed at a qualified workshop.

The ESC - in particular in conjunction with the trailer stabilisation system^* link► - makes it easier to stabilise a trailer if it starts to skid or sway. You should keep the ESC switched on at all times.

If you hitch up a trailer onto a vehicle with a factory-fitted towing bracket, the towing mode for the air suspension is switched on automatically. Operation of the air suspension is then restricted while the vehicle is moving. Should you want to deactivate the towing mode during your journey (if using a bicycle rack, for example), select the following on the infotainment system: MENU button > Car > left control button > Vehicle settings > Air suspension: trailer.

On vehicles with a retrofitted towing bracket, the towing mode is not switched on automatically. Switch on the towing mode before hitching up the trailer and switch it off again before unhitching the trailer.

In hot weather, keep an eye on the coolant temperature gauge link►. When climbing long hills with the engine running fast in low gear, the coolant temperature can increase. Reduce speed immediately if the LEDs light up at the top end of the scale.
