How To Adjust The Cadillac Celestiq Smart Glass Roof Tint

The high-priced, massively customizable Cadillac Celestiq halo luxury sedan includes a huge selection of GM’s latest technology, some of it unique for the Celestiq at this point in time.
Now, GM Authority is putting the spotlight on how to operate the Cadillac Celestiq’s Smart Glass Panoramic Roof, which offers a high level of adjustability to the sunroof’s variable tinting.
Control over the Cadillac Celestiq Smart Glass Roof can be handled either using the switch on the right-hand side of the overhead console, or by using the virtual controls of the front or rear display screens. Using the screens, the user should navigate to the Control and Safety Menu and select the Tint option.
One choice is to let the Celestiq automatically change the tint as appropriate. The vehicle will sense the current light levels and set the Smart Glass roof to the darkest tint during the day and the lightest overnight by default. However, it’s also possible to change the tint as desired using the console or displays.
The Smart Glass roof has five tint levels, ranging from a nearly colorless tint that is close to completely clear to a dark tint. Depending on the options chosen, each of the panoramic roof’s panels can be set to a separate tint, or all can be given the same tint. The vehicle offers five different tint modes to choose from:
- Individual mode lets the occupants choose each panel’s tint level separately from 0 percent to 100 percent in 25 percent increments.
- All Clear mode sets all sunroof panels to 0 percent opacity.
- All Dark mode sets all sunroof panels to 100 percent opacity.
- Automatic mode lets the vehicle set tint as already described.
- Sync or Synchronous mode sets all panels to 50 percent opacity, with a gradient bar or slider then usable to adjust the tint.
Smart Glass achieves its results using nanotechnology, as GM Authority detailed in a previous article. The Cadillac Celestiq is the first GM production vehicle to feature Smart Glass tech, though it has appeared earlier in concept vehicles.
Beneath the sheet metal, the Cadillac Celestiq is underpinned by the GM BEV3 platform. Power is supplied by a 111 kWh battery pack. The Celestiq continues to feature a starting MSRP of $340,000 and is hand-built at the GM Global Technical Center in Michigan.
