The myCadillac Mobile App enables you to use your smartphone to interact with your vehicle from wherever you are. You can remote start, unlock and lock your vehicle, view your fuel life and tire pressure and more on properly equipped vehicles.

Download the App

Throughout 2021 and beyond, the myCadillac Mobile App is being redesigned with a new personalized experience — and the updates to your home screen are just the start.

If you’d like to demo the app before you download it, check out the Connected Services Demo and select the Cadillac mobile experience. 


The app’s home screen simplifies your ownership experience with features that help keep you informed and in control. The features you’ll see depend on your service plan and how your vehicle is equipped.

  1. Tap the User icon (your initials) in the upper-left corner to access your Account information.

  3. Tap the Menu icon (three dots) in the upper-right corner to get help or schedule service.


If your vehicle and service plan support remote commands (e.g., engine start/stop), you’ll find them right on the app’s home screen.

  1. Tap and hold one of the remote command icons to start a request. The app will tell you to keep holding until the request is complete. It may take a few seconds.
