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 ⇒ !

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

Lights and vision features

Adaptive Front Lighting System (AFS)
The Adaptive Front Lighting System (AFS) works only with the low beams switched on and only at speeds above about 6 mph (10 km/h). The swivel-mounted lamps automatically improve road illumina-tion during cornering.
In some models, the headlights will turn independently, even when driving straight ahead. They can adjust according to the weather conditions and the speed of the vehicle to better light up the road ahead. The bulbs return to their original position after a short period of time, depending on the vehicle speed.
On vehicles equipped with the Adaptive Front Lighting System, the feature is switched on and off via
the Assistants menu in the instrument cluster display ⇒ page 16, Volkswagen Information System.
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.
x If automatic headlights (!54/) are switched on, the low-beam headlights still may not be switched on in fog or heavy rain. You have to switch on the low-beam headlights yourself.
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.

Instrument panel lighting and headlight range adjustment

Fig. 81 To the left of the steering wheel: Thumbwheel to adjust instrument panel lighting 1.

Headlight range adjustment
For vehicles equipped with halogen headlights: The headlight range cannot be manually adjusted. If you believe the headlights are not properly adjusted or are not sure, have them checked immediately
by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility ⇒ .
For vehicles equipped with HID (Xenon) headlights: The headlights are equipped with an automatic leveling feature that automatically adjusts the headlight range to the vehicle loading condition once the
low beams are switched on ⇒ .
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
If the automatic leveling feature of the headlights does not work properly or at all, the head-lights could blind and distract other drivers. This can lead to a crash and serious personal injuries.
x Have headlight range adjustment checked immediately by an authorized Volkswagen dealer or an authorized Volkswagen Service Facility.
Interior and reading lights

The self-dimming feature can be switched on and off with the switch on the inside mirror (2) A or (2) B. When self-dimming is activated, the indicator light (1) is on.
There are two sensors in the interior mirror housing:
x One sensor on the side facing the interior to measure light from the rear of the vehicle ⇒ fig. 89 A
(3) or ⇒ fig. 89 B (3).
x One sensor on the side facing the windshield to measure light from the front of the vehicle ⇒ fig. 89 C (4).
If the ignition is switched on, the mirror automatically darkens depending on the amount of light shining into the vehicle from the rear.
The self-dimming feature is deactivated when you shift the transmission into reverse or switch on the interior lights or the reading light.
Do not attach external navigation devices to the windshield or in the vicinity of the self-dimming inside
mirror ⇒ .
WARNING
The illuminated display on an external navigation device can cause the self-dimming inside mirror to malfunction, which can result in crashes and serious injuries.
x Malfunctions in the self-dimming function can result in the inside mirror being unable to evaluate the exact distance of vehicles in the rear or other objects.
If the light striking the sensor is filtered or blocked (such as by a sunshade), the self-dimming inside mirror will not work properly or may not work at all.
Outside mirrors

Fig. 91 In the front doors: Rotary knob for the mechanically adjustable outside mirrors.

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 de-signed 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 per-missible 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.
