Enjoy the ultimate ownership experience with your vehicle’s mobile app.

Your vehicle mobile app1 is among the most comprehensive of its kind, using OnStar to let you remotely control your vehicle from your smartphone. You can check your oil life, see where your vehicle is parked, start it up, lock or unlock it, and much more. With a properly equipped vehicle, your vehicle’s mobile app can enable you to:

  • Drive with confidence, because you can monitor oil life, tire pressure, remaining fuel, fuel efficiency and more.
  • Conveniently schedule service or maintenance through your Dealer.
  • Safely lock and unlock your vehicle or activate the horn and lights.
  • Stay warm in cold weather by remote starting or stopping your vehicle (if factory-equipped).
  • Get Roadside Assistance2 if you’re stranded, have a flat tire or need a tow truck.
  • Easily keep track of where you parked — the app can note the parking location, and you can set a timer to alert you when your meter is expiring.
  • Instantly access your vehicle’s owner’s manual.
  • Manage in-vehicle Wi-Fi® hotspot settings, including your hotspot name and password (if your vehicle is Wi-Fi–equipped).3
  • Get where you’re going easily — search for destinations and send the directions to your OnStar Turn-by-Turn Navigation system or send destinations to your vehicle’s in-dash navigation system (if equipped).4
  • Pinpoint your vehicle’s location on a map using the Vehicle Locate service.5
  • Contact an OnStar Advisor, your preferred Dealer, or the Dealer nearest you.

Standard for five years on eligible 2015 model year and newer vehicles. Some features require paid OnStar service.
