Official summary
SERVICE INFORMATION When the headlamp switch is set to the AUTO position, AND the fog lamp switch is turned ON, ... the fog lamps and headlamps are designed to come on, regardless of ambient lighting. If the customer would prefer that both the headlamps and fog lamps not come on during daylight conditions while in AUTO mode, perform the steps in this bulletin to disable the fog lamp override feature. See this bulletin for more detail.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
