2017 VOLKSWAGEN JETTA service

High Intensity Discharge (HID) headlights provide bright, uniform lighting to help you see and be seen. The light comes from an electric arc between two electrodes in the gas-filled bulb. Over time, the electrodes can wear down and the gap between them will get wider. The HID lamp’s control unit then increases the voltage to keep the arc’s brightness constant. However, the commonly called “Xenon” bulbs will also ultimately burn out. Before they burn out, HID lamps can flicker. A message will then appear in the MFI. This is your reminder to see an authorized Volkswagen dealer or an authorized Volkswagen Service facility to check the headlights.

x Light switch in position  if the vehicle has no orientation lighting ⇒  Coming Home/Leaving Home features (orientation lighting).
WARNING
Daytime running lights are not bright enough to let you see ahead or be seen by others when it is dark.
x Always switch on the low-beam headlights at dusk or when it is dark and whenever the weather is bad or visibility is poor.
x Never use the daytime running lights to see where you are going. They are not bright enough and will not let you 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 with the daytime running lights. Unless the taillights are on, a vehicle cannot be seen by others in bad weather, at dusk, or when it is dark.
x Even if automatic headlights (!54/) are switched on, the low-beam headlights may still not come on by themselves in fog or heavy rain. You have to switch on the low-beam headlights manually.
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.
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.

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.

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
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

WARNING
New tires or tires that are old, worn or damaged cannot provide maximum control and brak-ing performance.
x Improper care and handling of tires and wheels can reduce driving safety and cause acci-dents and severe injuries.
x Install only radial tires of the same make, the same dimensions (tread circumference), and similar tread profile on all 4 wheels.
x New tires tend to be slippery and must be broken in. Always drive with special care for the first 350 miles (560 km) to help reduce the risk of losing control, a collision, and serious per-sonal injuries.
x Check tire inflation pressure regularly when the tires are cold and always maintain the prescribed tire pressure. Low tire pressure can cause tires to get too hot, resulting in tread separation, sudden loss of pressure, and blowouts. Tires with excessively low pressure flex (bend) more, which can cause the tire to overheat and fail suddenly without warning.
x Check tires regularly for wear and damage.
x Never drive with worn or damaged tires (for example, tires with punctures, cuts, cracks, blisters, or bumps). Driving with worn or damaged tires can lead to loss of vehicle control, sudden tire failure including blowouts and sudden deflation, crashes, and serious personal injuries.
x Have worn or damaged tires replaced immediately.
x Never exceed the maximum speed rating or the maximum load rating of the tires on your vehicle.
x The effectiveness of the driver assistance systems and the braking support systems de-pends on the tire traction.
x If you notice unusual vibration or if the vehicle pulls to one side when driving, always stop as soon as it is safe to do so and check the wheels and tires for damage.
x To reduce the risk of losing control, crashes, and serious personal injuries, never loosen the bolts on wheels with bolted rim rings.
x Never mount used tires on your vehicle if you are not sure of their past use. Old, used tires and wheels may have damage that cannot be seen that can lead to sudden tire failure and loss of vehicle control.
x Tires age even if they are not being used and can fail suddenly, especially at high speeds, causing loss of vehicle control, accidents, and severe personal injuries. Tires that are more than 6 years old can be used only in an emergency and even then only with special care and at low speed.
For technical reasons it is usually not possible to use wheel rims from other vehicles. Even wheel rims from the same model may not fit properly. Check with an authorized Volkswagen dealer or au-thorized Volkswagen Service Facility if necessary.
