2017 VOLKSWAGEN JETTA warning light

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.
Coming Home/Leaving Home features (orientation lighting)

Leaving Home Action
Switch on: – Unlock the vehicle if the light switch is in the !54/ position and the low-light sensor registers darkness.
Switch off: – Automatically after preset delay period is over. – Lock the vehicle. – Turn the light switch to the / position. – Switch the ignition on.

The delay period can be adjusted in 10 second intervals and the function can be switched on and
off in the Lights & Vision menu ⇒  Volkswagen Information System.
If the Coming Home feature is switched on and the driver door is opened, no warning chime will sound to alert you that the lights are still on.
Instrument panel lighting and headlight range adjustment

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

WARNING
Unsuitable, worn, or damaged tie-down straps (elastic or non-elastic) can snap or come loose during braking or other maneuvers or in a collision. Objects secured with these straps can then come loose and fly through the passenger compartment, causing severe personal inju-ries or death.
x To help prevent baggage or other items from coming loose and flying around, always use suitable undamaged tie-down straps.
x Securely fasten the tie-down straps to the tie-downs.
x Loose or improperly secured objects in the luggage compartment can slide about sudden-ly and change the vehicle's handling.
x Secure even small and light objects. Loose objects in the luggage or passenger compart-ment can fly about during sudden braking maneuvers or in the event of an accident and in-jure occupants.
x Never exceed the maximum allowable load on the tie-downs when securing objects.
x Never secure a child restraint to the tie-downs.
WARNING
Elastic straps have to be stretched when being attached to the tie-downs in the luggage compartment. Hooks on these straps can cause serious personal injury if not handled properly and attached securely.
x Always protect eyes and face from injury from the hooks when attaching them to the tie-downs in the luggage compartment.
x Always hold the hooks on elastic straps firmly when attaching to the vehicle and do not let them snap back and hit you.
x First attach the hooks on the straps to the tie-downs at the rear seat backrest in the lug-gage compartment and then to the tie-downs near the loading edge of the luggage compart-ment. This way, if one of the hooks on the elastic straps snaps back, it will move away from you, decreasing the risk of personal injury.
The maximum load for the tie-downs is about 380 lbs. (172 kg).
For suitable straps and luggage stowage systems, please see an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

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.

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

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.
