In most Jetta models, you turn on the headlights with a control on the left side of the steering column or a dash-mounted dial; set it to Auto or On, and daytime running lights may activate automatically.
This guide covers the common lighting setups across Jetta generations, how to operate them, and what to do if the lights don’t come on as expected.
Locating the lighting controls
The exact arrangement varies by year, but you’ll typically find either a stalk on the left of the steering column or a dedicated dial on the dash near the headlight symbols.
Stalk-based controls (older and some mid-cycle Jettas)
Use this description for models where the headlight control is built into the left stalk with a rotating end or switch.
- With the ignition on, rotate the end of the stalk to the desired position: Off, Parking lights, or Headlights. If your model has an Auto setting, select Auto to enable automatic headlight operation based on ambient light.
- For high beams, operate the stalk according to your model’s design (often you push the stalk forward to activate high beams and pull it back to flash or momentarily toggle). If unsure, check the symbol on the stalk.
- Fog lights, if equipped, are usually activated by an additional ring on the headlight switch or a separate button—only when the headlights are on or in Auto mode, depending on the design.
Concerning this setup, remember that the exact actions can vary by year and trim; consult your owner’s manual if you’re unsure.
Dash-mounted controls (newer Jettas, including recent Mk7/Mk8)
Newer Jettas often place the primary headlight control on a dial or switch on the dash to the left of the steering wheel.
- Locate the rotary dial and turn it to Auto to let the system manage headlights in low light, or to On to illuminate the headlights manually. Off will switch all exterior lights off when the ignition is on.
- Daytime running lights (DRLs) typically illuminate automatically when the engine is running, so you may not see manual control needed for daytime lighting.
- Fog lights: If your vehicle has fog lights, the dial or a nearby button will include a fog symbol—activate them only when visibility is reduced and headlights are on.
Note that some trims may merge the fog light control with a separate switch or require a different sequence; again, the manual is the most reliable source.
Automatic headlights and safety features
Most modern Jettas support automatic headlights that turn on when it’s dark outside and switch off when you exit the vehicle. If you don’t see the lights coming on in low light, verify that Auto is selected and that the sensor on the windshield area is clean and unobstructed by snow, ice, or a sticker.
Troubleshooting common issues
If the lights won’t come on or behave unexpectedly, try these quick checks before calling service:
- Ensure the ignition is on and the headlights control is set correctly (Auto or On).
- Check fuses related to exterior lighting in the fuse box.
- Look for obstruction on the automatic light sensor or damaged wiring.
- If available, consult the vehicle’s owner’s manual for model-specific instructions.
When in doubt, contact a dealer or a qualified technician for safety-critical lighting issues.
Summary
Lighting controls in a Jetta vary by generation. Older models generally use a left-side stalk with a rotating headlight control, while newer models commonly employ a dash-mounted dial with an Auto setting for automatic headlights. Daytime running lights usually operate automatically, and fog lights are available on models equipped with that feature. If you’re unsure, refer to your owner’s manual or consult a Volkswagen dealer for model-specific guidance.
