In most Audi models, daytime running lights (DRLs) are automatic and illuminate whenever the ignition is on and the lighting control is set to Auto (or On, if Auto isn’t available). You typically do not need to manually switch DRLs on; they should come on during daytime driving once the car is started.
What DRLs are and how they work
Daytime running lights are a safety feature that keeps your Audi visible in daylight. In many modern Audis, DRLs use LED elements and turn on automatically when the engine is running. They are not the same as full headlights; they are designed to be lower-intensity and are intended for daytime visibility. Depending on the market and model, DRLs may dim or switch to low beams when lighting conditions require it.
Steps to ensure DRLs are active
The following steps help ensure DRLs illuminate during daytime driving.
- Start the engine or turn the ignition to the Run position.
- Rotate the headlight control to Auto (or to On if Auto isn’t available). In most Audi models, DRLs activate automatically when the switch is in Auto or when the engine is running with the switch in On.
- Check the exterior lights or the instrument cluster to confirm that DRLs are on.
When using Auto mode, DRLs should be on by day and may transition to full low-beam headlights as ambient light decreases or when required by the system.
What to do if DRLs don’t come on
If DRLs don’t illuminate as expected, try these checks. Note that DRL availability and behavior can vary by market and model.
- Verify the lighting control is set to Auto or On; ensure it isn’t set to Off or a parking-light setting.
- Check the vehicle’s MMI or instrument cluster for a Daytime Running Lights option and enable it if your model provides a configurable setting.
- Consult the Owner’s Manual or contact an Audi dealer for market-specific configurations or potential faults.
If you see a warning light or suspect a system fault, have the vehicle inspected by a qualified technician.
Market and model considerations
DRLs are standard in many regions and are designed to operate automatically. In some markets or for certain trims, there may be regional settings or dealer-programmed differences that affect DRL behavior. For precise instructions tailored to your Audi model year and country, refer to the owner’s manual or contact Audi support.
Summary
Most Audi daytime running lights automatically activate when you start the car and set the lighting control to Auto (or On). If DRLs don’t appear, check the lighting settings, consult the manual, or contact a dealer for model-specific guidance.
