How do I change the infotainment screen brightness while parked?

Start with the infotainment screen’s own settings menu rather than turning dashboard controls at random. Look for a path such as Settings, then Display, and an item called Brightness. For example, the 2016 Chevrolet Traverse manual places screen settings under Settings on the Home Page, then Display, and lists Brightness as adjustable. That example applies to that specified model and year, not every vehicle. [S1]

A practical sequence is:

1. Keep the vehicle parked while you look through the menus.
2. Open Settings, then look for Display, Screen, or a similar label.
3. Adjust Brightness a little at a time and check the result.
4. If you cannot find the control, check the owner’s manual index for “display brightness” or “screen settings.”

If your screen has no visible setting, don’t assume a particular knob or wheel controls it. The manual for your exact vehicle is the best guide to its controls.

Not necessarily. A brightness wheel may adjust the instrument cluster—the gauges and driver display—rather than the infotainment screen. Chevrolet’s display-customization guide describes a thumbwheel for cluster brightness on the vehicles it covers; it does not establish that the wheel changes infotainment brightness or that every vehicle has one. [S2]

To check without guessing, change the wheel slightly while parked and observe which display changes. If the gauges change but the central screen does not, return to the infotainment menus or consult the manual for a separate screen control. If several displays change, note exactly what responds so you can confirm the intended control in the manual. Don’t force a dial or switch if its purpose is unclear.

Check the display settings and the owner’s manual for terms such as “day,” “night,” “dim,” “automatic,” or “brightness.” A day/night setting might be presented as two values, while an automatic option may be listed by name; those are things to look for, not features to expect in every vehicle. The 2016 Traverse manual excerpt confirms an adjustable Brightness setting, but does not establish separate day/night or automatic screen-brightness settings. [S1]

Keep the distinction between the infotainment screen and the instrument cluster in mind. Chevrolet’s guide says the covered vehicles’ cluster brightness adjusts automatically in daylight and describes a nighttime thumbwheel behavior, but that information is about the cluster—not a universal infotainment-screen feature. [S2] If the manual doesn’t describe an option, the available information here cannot confirm that your vehicle has it.

Use the manual for the exact make, model, and year, and search its index for “brightness,” “display,” or “infotainment.” Menu wording can differ, so treat the Chevrolet example as an illustration of one menu path, not a universal set of instructions. If you still cannot identify the control, record what you see and ask a dealer or qualified service professional to point out the relevant setting.

Here is a copyable note:

“Vehicle: [year, make, model] Screen affected: [center infotainment screen / instrument cluster / other] Menu path tried: [what I opened] Setting labels shown: [exact wording] Control tested: [menu slider / wheel / other] What changed: [which display became brighter or dimmer] Question: Does this vehicle have separate day/night or automatic infotainment-screen brightness?”

This keeps the question focused and helps distinguish a screen setting from a cluster control. The cited examples do not establish which features your particular vehicle has; its manual or a knowledgeable service contact can confirm that.
