WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
A chime or audio warning activates as a turn signal on warning if the turn signal remains ON for a specific distance traveled. The turn signal warning sounds when a turn signal remains active and the vehicle has traveled a distance of 1.2 km (0.75 mi).
The driver information center (DIC) turns the turn signal reminder OFF when the ignition switch or turn signal switch is turned to the OFF position.
