Complete Control At Your Fingertips

There’s an easier, more convenient way to interact with your vehicle, and you can do it from afar. The myChevrolet®, myGMC®, and myCadillac® Mobile Apps* allow you to lock and unlock your car in case you lose your keys, start the engine and the AC before you get in on those extra hot days, check charge status, fuel levels and vehicle health for stress-free drives, and locate your car with a tap so that you skip the carpark search. It’s the better way to maximize every drive.

Push Your Vehicle’s Capabilities

Transform every drive into a smart drive with the Vehicle Mobile App* - Start your vehicle, monitor health, check tire pressure, and enjoy the convenience of remote start.

Take Control

Remotely start or stop your properly equipped and activated vehicle* and start your AC before you get in for a cooler drive on hotter days. Lock and unlock the doors in case you locked your keys inside, or sound the horn and flash the lights, all from the carpark, sofa, or anywhere else you may be.

Check Your Vehicle Status

Your Vehicle Mobile App also keeps you on top of your vehicle's health. If you have trial or Bundle* or Connect plan*, you can get updates on your oil life, tire pressure (if properly equipped) and fuel level, so you have less things to worry about on the road. You can also get notified if your vehicle needs an oil change or is due for a service, and you can schedule the appointment with your preferred Dealer without making a call, for even more convenience.

Find Your Vehicle

Forgot where you parked? That’s not a problem with the Vehicle Mobile App. If you have the Remote Access* or Unlimited Access Plan*, you can use Vehicle Locate to pinpoint your vehicle's approximate location on a map with the touch of a button, saving you time and energy. You can also set arrival/departure notifications and boundary alerts for your vehicle so that you’re always in sync with its movements.
