Ensure the ignition is turned on.
Locate the headlight switch, which is usually positioned near the steering wheel.
Turn the headlight switch to the "Auto" position. This setting automatically turns on the daytime lights when the vehicle's ignition is on and the ambient lighting is bright.
The daytime lights will now be turned on. Please remember that the specific steps and controls may vary depending on the specific model and year of your BMW. It's always best to consult the vehicle's owner's manual for accurate and up-to-date instructions specific to your car.
