Special seat heating features
On the driver and the passenger side, the seat heating may resume at the setting that was set when the ignition was switched off. However, this feature only works if the key is not taken out of the ignition switch, or, for vehicles with Keyless Access, the driver door is not opened or the vehicle is not locked.
People suffering from a low level of perceived pain or a lowered awareness of pain as from medica-
tion, paralysis, or chronic illness (e.g. diabetes) should NEVER use the seat heating feature ⇒ !
The use of seat heating by persons with these conditions could result in burns to the back, buttocks, and legs that may take a long time to heal and may never heal completely. If you have any of these conditions, you should take regular breaks and get out of the vehicle, particularly on long trips. Consult your doctor for advice regarding your specific condition.
WARNING
Certain medical conditions, such as paralysis and diabetes, and certain medications can increase the risk of serious burns when the seat heating feature is switched on.
x Vehicle occupants who have a low level of perceived pain or a lowered awareness of pain can receive serious burns to the back, buttocks, and legs that take a long time to heal or may never heal completely.
x Never use the seat heating feature if you or your passengers are at risk of being burned because of a medical condition. Take regular breaks and get out of the vehicle, particularly on long trips. Consult your doctor for advice regarding your specific condition.
x Never let exposed skin remain in contact with the seat upholstery when the seat heating is being used.
WARNING
A wet seat can cause the seat heating to malfunction and increase the risk of serious burns.
x Always make sure the seats are dry before using the seat heating.
x Never sit on the seat with wet clothes.
x Never put damp or wet things including clothes on the seat.
x Never spill liquids on the seats.
NOTICE
x To help prevent damage to electrical and other parts in the seat, do not kneel on the front seats or apply concentrated pressure to a small area of the seat or backrest.

Daytime running lights (DRL)
Separate lamps are installed in the headlights or in the front bumper for the daytime running lights (DRL).
When the daytime running lights are switched on, only these separate lamps come on ⇒ .
The daytime running lights are switched on whenever the ignition is switched on and the light switch is in position /. The indicator light  or DRL may come on in the instrument cluster to indicate that the feature is active, Lights.
WARNING
Crashes and other accidents can happen when you cannot see the road ahead and when you cannot be seen by other motorists.
x Never use daytime running lights (DRL) to see where you are going. DRL are not bright enough to light up the roadway and be seen by other motorists. You will not be able to see far enough ahead for safety, especially at dusk or when it is dark. Always switch on the low-beam headlights at dusk or when it is dark.
x The taillights do not come on when the daytime running lights are switched on. A vehicle without taillights on cannot be seen by others in bad weather, at dusk, or when it is dark.
In cool or humid weather, the insides of the headlights, the rear lights, and turn signals can temporarily fog up. This is normal and does not affect the service life of the vehicle's lighting system.

WARNING
Headlights that are aimed too high because of the way the vehicle is loaded can blind and distract other drivers. This can lead to a crash and serious personal injuries.
x Always make sure the headlights are adjusted to loading conditions so that they do not blind others.

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

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 11/4 inches (32 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 11/4 inches (32 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 11/4 inches (32 mm) to 2 inches (50.8 mm) or more 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.

(F) 26.1 inches (663 mm)
(G) 40.9 inches (1040 mm)
WARNING
Improper or incorrect connections to the vehicle electrical system can cause malfunctions that affect the entire vehicle electrical system and cause accidents and serious personal injury.
x Never connect the electrical system of the trailer directly to the electrical connections of the rear lights or other unsuitable power sources. Use only a suitable connector to provide power to the trailer.
x Have any trailer hitch retrofit or other work on a trailer hitch done by a qualified workshop.
WARNING
