Towing a trailer

Safe Driving with a Trailer

  • Always see the permissible towing capacity, vertical coupling load and rear-axle load.
    Please see the chapter "WEIGHTS" on page 341.
  • When connected, the trailer must always be horizontal behind the towing vehicle. If necessary, use a trailer with an adjustable drawbar.
  • When the vehicle is driven in the mountains, the engine output decreases as altitude increases.
    The maximum weights stated are the values at sea level. The total permissable weight of the car-trailer combination must therefore be reduced by 10 % for each increment of 3280 ft. (1000 meters) altitude. A fractional increment counts as the full 3280 ft. (1000 meters).
    Please take this into consideration when planning your route.

Distributing the load

  • Distribute the load in the trailer so that heavy objects are as close to the axle as possible.
    Always safeguard all objects against slipping and tie them down securely.
  • You should make the best possible use of the trailer coupling's rated vertical coupling load when loading the trailer, but never exceed it.

Tire pressure

  • Select the vehicle tire pressure for full load when towing a trailer.
  • Please see the chapter "TIRE PRESSURE FOR COLD TIRES 68 °F (20 °C)" on page 339.
  • Check the tire pressure of the trailer's wheels according to the manufacturer's instructions.

Door mirrors

  • If the width of the trailer obstructs your view of the traffic behind the trailer, you must have additional door mirrors fitted.

Headlights, lights

  • Always check the headlight adjustment before driving with a trailer.
    If necessary, correct with the headlight beam adjustment function.
  • Check whether the plug of the trailer is plugged into the towing vehicle and whether all lights function.

Driving with a trailer
When towing a trailer you must under all circumstances adapt your speed to prevailing road and driving conditions. Towing at excessive speed can result in loss of control. Observe country-specific laws for driving with trailers.

  • Carefully and gradually familiarize yourself with the handling and braking behavior of the car-trailer combination.
  • Do not drive with the towing vehicle empty and the trailer loaded.
    If this unfavorable combination is unavoidable, please drive especially slowly.
  • Bear in mind the different vehicle handling and size in situations such as braking, parking, cornering and overtaking, etc.
  • The driving stability of the car-trailer combination worsens as the speed increases. Therefore, drive especially slowly on downhill stretches and in the case of unfavorable road and weather conditions (such as wind).
  • Drive in an appropriately low gear on downhill stretches in order to make use of the engine braking effect.
  • Slow down immediately if the trailer starts to sway. Do not countersteer; brake if necessary.
    Never attempt to straighten out the car-trailer combination by accelerating.
  • Activate the off-road driving program when driving off on steep slopes.
  • Under no circumstances may people, animals or objects be in the space between the trailer and the towing vehicle when the vehicle is moving.
  • When reversing, bear in mind that ParkAssist is not active.
  • Always see the permissible towing capacity, vertical coupling load and rear-axle load.
    Please see the chapter "WEIGHTS" on page 341.


  • Please take into consideration that driving with a trailer places markedly greater stress on all vehicle components. Expert inspection and maintenance after every use are indispensable prerequisites for proper functioning and safety.
