2019 Chevrolet Colorado Owner’s Manual — Interior Mirrors

If equipped with OnStar, the vehicle may have three control buttons at the bottom of the mirror. See OnStar Overview 0 363.

To avoid accidental OnStar calls, clean the mirror with the ignition off. Do not spray glass cleaner directly on the mirror. Use a soft towel dampened with water.

If equipped, push the tab forward for daytime use and pull it rearward for nighttime use to avoid glare from the headlamps from behind.

If equipped, the mirror will automatically reduce the glare of the headlamps from behind. The dimming feature comes on each time the vehicle is started.
