2017 VOLKSWAGEN JETTA high beam

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.

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.
