VOLKSWAGEN PASSAT 2015 B8 / 6.G Owners Manual

Trailer towing

WARNING
Improper use of the trailer hitch can cause accidents and injuries. An improperly installed, incorrect, or damaged trailer hitch can cause the trailer to separate from the towing vehicle and cause serious personal injuries.
x Only use an undamaged, properly mounted trailer hitch.
x Never repair or modify the trailer hitch.
x To reduce the risk of injury in rear-end collisions, and the risk to pedestrians and cyclists when the vehicle is parked, always remove the ball mount when you are not towing a trailer.
x Never install a “weight distributing” or “load equalizing” trailer hitch on your vehicle. The vehicle was not designed for these kinds of trailer hitches. The trailer hitch attachment can fail, causing the trailer to tear loose from the vehicle.
WARNING
Improper trailer towing can cause loss of vehicle control and serious personal injury.
x Driving with a trailer and carrying heavy or large things can change the way the vehicle handles, increase the distance it needs to stop safely, and cause accidents.
x Always secure the load properly with suitable and undamaged straps so that the load will not shift.
x Always adapt your speed and driving to the heavier load and the weight distribution in the vehicle. Take road, weather, traffic, and visibility conditions into account as well.
x Reduce your speed even more than you otherwise would when going downhill and under unfavorable load, weather, or wind conditions.
x Trailers with a high center of gravity tip more easily than trailers with a low center of gravi-ty.
x Always avoid sudden maneuvers and hard braking.
x Be especially careful when passing other vehicles.
x Reduce speed immediately if the trailer shows the slightest sign of swaying.
x Never try to stop the swaying by accelerating.
x Always obey speed limits. In some areas, the speed limits for vehicles towing trailers are lower than for vehicles without trailers. Never drive faster than 50 mph (80 km/h; under ex-ceptional circumstances 60 mph - 100 km/h) when towing a trailer. This applies even if the local speed limit is higher.
If you are driving a new vehicle or a vehicle with a new or rebuilt engine, do not tow a trailer
during the break-in period, about 600 miles (1000 km) ⇒  Parts, accessories, repairs and modifica-tions.
If you tow a trailer, your vehicle may need maintenance more often because of the extra load it has to move.
When you are not towing, remove the trailer hitch ball. This helps keep the trailer hitch from causing damage to your vehicle and to others if your vehicle is hit from behind.
Some models need a trailer hitch to tow or tow-start other vehicles. You may want to always carry the ball mount in the vehicle after it has been removed. Be sure to stow it securely.

Technical requirements

WARNING
x An improperly installed or incorrect trailer hitch can cause a trailer to separate from the tow vehicle and cause serious personal injuries.
x If you don't have to tow a trailer any more, remove the entire trailer hitch. Always seal all bolt holes to prevent water and deadly exhaust fumes from getting into the vehicle.
NOTICE
x If the trailer lights are not connected properly, the vehicle's electronics may be damaged.
x If the trailer uses too much electricity, the vehicle's electronics may be damaged.
x Never connect the electrical system for the trailer directly to the electrical connections for the rear lights or to any other unsuitable power sources. Use only a suitable connector to provide power to the trailer.
If you tow a trailer frequently, Volkswagen recommends having the vehicle serviced between the regular maintenance and inspection intervals because of the extra load it has to pull.
Hitching up and connecting a trailer

If the engine is switched off and accessories in the trailer are on and use electricity from the vehicle, the vehicle battery will be drained as long as the electrical systems of the vehicle and the trailer are connected.
Loading the trailer

WARNING
Exceeding the gross weight ratings for axle, tongue, vehicle, trailer or combined weight can cause accidents and serious personal injury.
x Never exceed the specified values.
x Never let the actual weights at the front and rear axles exceed the Gross Axle Weight Rat-ing. Never let the combined front and rear weights exceed the Gross Vehicle Weight Rating.
WARNING
Trailer loads that are not properly secured can shift when the vehicle is moving or braking and suddenly change the way the vehicle handles, causing accidents and severe injuries.
x Always load the trailer properly.
x Always secure the load properly with suitable, undamaged straps that can be tightened so that the load cannot shift.
Driving with a trailer

x Do not release the parking brake lever until the engine starts to move the vehicle forward. If your vehicle has an automatic transmission, you can also depress and hold the brake pedal for added braking and then let up on the brake pedal when you feel that the vehicle “wants” to move forward.
x Drive ahead slowly.
WARNING
Improper trailer towing can cause loss of vehicle control and serious personal injury.
x Driving with a trailer and carrying heavy or bulky items changes the way the vehicle han-dles and increases the distance it needs to stop safely.
x Always watch what is happening up ahead and around you. Brake earlier than you would if you were not towing a trailer.
x Always adapt your speed and driving to the heavier load and the weight distribution in the vehicle. Take road, weather, traffic, and visibility conditions into account as well.
x Reduce your speed even more than you otherwise would when going downhill and under unfavorable load, weather, or wind conditions.
x Drive especially carefully and accelerate gently. Always avoid sudden maneuvers and hard braking.
x Be especially careful when passing other vehicles.
x Reduce speed immediately if the trailer shows even the slightest sign of swaying.
x Never try to stop the swaying by accelerating.
x Always obey speed limits. In some areas speed limits for vehicles towing trailers are lower than for vehicles without trailers.
Ball mount

Fig. 120 Dimensions of the ball mount support.

These dimensions are important because they help determine the way that the forces that arise during towing are applied to the receiver and its attachments to the vehicle. If you buy a ball mount and ball, make sure that they meet the following specifications.
Ball mount dimensions
x The drop height (A) from the center of the ball to the center of the hole for the securing pin on the ball mount must be at least 1 inch (25.4 mm) and at most 27 /8 inches (73 mm).
x The pin-to-ball distance (B) from the center of the ball to the center of the hole for the securing pin on the ball mount must be no more than 7 inches (178 mm).
x The ball diameter must be no more than 17/8 inches (47.6 mm).
A ball mount and ball combination that does not meet these specifications can damage your vehicle
and may even fail in use ⇒ .
Never install a “weight distributing” or “load equalizing” trailer hitch on your vehicle. The vehicle is not
designed for this kind of trailer hitch ⇒ .
WARNING
An improperly installed or unsuitable trailer hitch can cause the trailer to separate from the towing vehicle and result in a major accident with serious personal injuries.
x Have any trailer hitch retrofit or other work on a trailer hitch done by a qualified workshop.
CAUTION
The ball mount sticks out behind the rear bumper and can cause injury to pedestrians and cyclists.
x To reduce the risk of injury in rear-end collisions, and the risk to pedestrians and cyclists when the vehicle is parked, always remove the ball carrier when you are not towing a trailer.
NOTICE
x Never use a ball larger than 17/8 inches (47.6 mm) on your vehicle. The vehicle was not designed to tow heavier trailers with a receiver larger than the specified ball. The increased loads can damage the attachment points for the trailer hitch.
x Never use an adapter to increase the size of the trailer hitch receiver from 17/8 inches (47.6 mm) to 2 inches (50.8 mm) or more than to tow a trailer that is heavier than the maximum permissible trailer weight that your vehicle can tow.
x You can use an adapter if required for the proper installation of a bicycle rack or other similar carrier as long as the maximum weight limits are observed. When using bicycle racks or similar carriers, make sure that the rear lights are not blocked.
x Only use trailer hitches that are approved by the hitch manufacturer for your vehicle and model.
