Cadillac CTS blue flag warning on instrument cluster on Cadillac CTS

Some Cadillac CTS owners report experiencing confusion when a blue dashboard indicator warning light, such as a blue flag, appears on the instrument cluster. While these blue or green lights are generally informational and indicate normal operation of a system, some owners may misinterpret them as potential issues. It is important to note that these lights are designed to inform drivers about the status of various vehicle systems and are not typically associated with immediate malfunctions. Therefore, seeing a blue flag warning is likely just a notification and does not require immediate attention from the owner.
