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.
Ensure that the following weights are not exceeded:
The applicable permissible values that may not be exceeded can be found:
on the vehicle identification plate more.
You will find the values approved by the manufacturer on the vehicle identification plates and those for the towing vehicle in the "Technical data" section more
The vehicle/trailer combination:
Do not exceed the legally prescribed maximum speed for vehicle/trailer combinations in the relevant country. Before beginning the journey, check the trailer's documents for the maximum permitted speed. In Germany, the maximum permissible speed is 80 km/h (100 km/h in exceptional cases).
The turn signals on the trailer are only guaranteed to work when incandescent bulbs are used. You can obtain more information on the installation of trailer electrics at any qualified specialist workshop.
When towing a trailer, set the tyre pressure for the rear axle of the towing vehicle to the setting for a fully laden vehicle more.
The trailer tow hitch is one of the most important components on the vehicle with regard to road safety. Observe the notes on operation, care and maintenance in the manufacturer's operating instructions.
You will find information about installation dimensions and loads in the "Technical data" section more.
You thereby make use of the braking effect of the engine and do not have to brake as often 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.
Observe the notes on ESP® trailer stabilisation more.
The figures for the gradient climbing capabilities from a standstill refer to sea level. When driving in mountainous areas, note that the power output of the engine, and with it its gradient climbing capability, decrease with increasing altitude.
If you cannot remove the key, the ball coupling may be dirty.
On vehicles with a narrow bumper, put the ball coupling recess cover back in place on the vehicle. Push the catches out to the sides and make sure that the cover is secure more.
If the trailer is equipped with LED lamps, indicator lamps in the instrument cluster may light up or the display may show a corresponding error message. The trailer lighting is identified as being faulty even though it is in working order. The reason for the error message may be that the current has fallen below the minimum of 50 mA.
