In most Audi models, fog lights activate once the headlights are on and you use the dedicated fog-light control. If your car doesn’t show a fog icon or button, check the owner’s manual for your exact model and year. This guide covers the common locations, how to operate them, and model-specific notes.
Where to find the fog light control
Fog light controls are located on or near the left-hand headlight switch in most Audis. The exact setup varies by generation, but the general idea remains the same: you either rotate the headlight dial to the fog symbol or press a dedicated fog button on the switch. If your vehicle has auto headlights, the fog function typically requires the headlights to be in a manual low-beam or auto low-beam position.
- Locate the headlight switch on the left side of the steering column. Look for a small symbol that resembles a headlamp with diagonal lines (the fog-light icon) on the dial or nearby button.
- Turn the switch to the fog-light position if your model uses a rotating dial with a fog symbol. You’ll usually need the low-beam setting active first.
- If there is a separate fog-light button, press it to toggle the front fog lights on or off. The dash will typically illuminate a corresponding fog-light indicator when active.
- Some models require pressing the stalk’s end or a different switch for fog lights; in those cases, refer to the specific vehicle manual for exact steps.
Front fog lights are normally designed to operate only when the headlights are on (low beams or auto mode with lights active). If the dash indicator does not show the fog-light symbol after following these steps, recheck the headlight position or consult the owner’s manual for your exact model.
Model variations and tips
Audis span many generations, and fog-light controls can differ slightly between trims and years. Here are common patterns you might encounter.
Newer Audi models (roughly 2015 onward)
In many 2015+ models, you will find a dedicated fog-light button integrated into the headlight switch. Steps are typically:
- Turn the ignition on and set the headlights to low beam or Auto with headlights active.
- Press the fog-light button or rotate the dial to the fog icon to enable front fog lights.
- Watch the instrument cluster for the fog-light indicator confirming activation.
Note: Some configurations may automatically enable fog lights in very low visibility when the fog switch is on, but others require manual activation as described above.
Always ensure you’re using fog lights only in appropriate conditions (dense fog, heavy rain, or mist) and switch them off when visibility improves to avoid glare for other drivers.
Older or base-trim Audis
Earlier models or trims without a dedicated fog-light button may require rotating the headlight dial to the fog symbol to engage front fog lights, with the low-beam position already active. If your model lacks a fog icon on the switch, consult the owner’s manual or a dealer for the exact method for your year and package.
- Front fog lights may be inactive if the car is in a mode that disables non-essential lights.
- Some models offer rear fog lights as a separate control, typically activated only when visibility is significantly reduced and usually in conjunction with the front fogs.
If you’re unsure about your specific Audi configuration, the quickest path to a definitive answer is to check the owner’s manual for your exact model and year or contact an authorized Audi service center.
Warnings and best practices
Fog lights are designed for reduced-visibility situations. They do not replace headlights and should be used appropriately to avoid blinding other drivers.
- Use front fog lights in fog, heavy rain, or snow, when visibility is reduced to a few hundred meters or less.
- Turn off fog lights once conditions improve to prevent glare for other road users.
- Do not use fog lights in clear nighttime conditions; many regions regulate fog-light use with penalties for improper use.
Rear fog lights, when equipped, should be used only in heavy visibility reductions and then turned off when conditions return to normal to prevent blinding drivers behind you.
Summary
To turn on Audi fog lights, ensure the headlights are on (low beam or Auto with lights active), then use the fog-light control—either by rotating the headlight dial to the fog icon or by pressing the dedicated fog-light button on the headlight switch. Model variations exist across generations, so if your car doesn’t follow the standard pattern, consult the owner’s manual or an Audi dealer to confirm the exact procedure for your year and trim. Remember to use fog lights only in appropriate conditions and switch them off when visibility improves.
