WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.

Instead of just warning the driver via the DIC when the vehicle tires are low, this feature provides audible and visual indication to the driver when they are putting air into the low tire to aid in achieving optimal tire pressure. The feature begins when the tire pressure telltale is illuminated for a low tire. When the driver starts to fill the low tire, the vehicle will flash the turn lamp of the corner that is being filled. This will provide feedback to the driver that a fill event is occurring. When the placard tire pressure is achieved, the vehicle will notify the driver with a single, short, horn chirp, similar to the one heard when locking the vehicle. The turn signal lamp of that corner will then stop flashing and become solid for a short period of time. If continuing to fill the tire and overfill occurs, the vehicle will notify the driver by sounding the horn three short chirps.
