Emergency

OnStar’s Automatic Crash response feature is your backup plan should you be involved in an accident, at which point a specially trained OnStar Emergency Advisor will be immediately connected to your vehicle. They will send emergency responders to your exact location if you request help or can’t answer.

You can also reach this emergency service by pushing the red SOS button. OnStar is available 24/7 so you can rest assured that you will be taken care of in a crisis. No matter what happens on the road, OnStar is your link to emergency service providers.

Security

OnStar Security Protection is a great way to protect your vehicle in the event of auto theft. With Stolen Vehicle Assistance, OnStar will work with the police to recover it.

If you find yourself stranded somewhere with an empty gas tank or a flat tire, Roadside Assistance can be reached with the push of your OnStar button. Shortly after, OnStar will contact a nearby car dealership, towing service or gas station and will send them your exact location.

Navigation

With OnStar Navigation Assistance, you can plan out your route ahead of time and send it to your vehicle via OnStar Turn-by-Turn navigation and eNav. The eNav feature is designed for convenience since it completely eliminates the need to manually enter an address while driving. Instead, you can program and send directions to your vehicle before you get behind the wheel.

Connectivity

With OnStar Hands-Free Calling, you’ll be able to stay connected and focused on the road ahead. All you need to do is push the Voice Command button to make or take a call. Once you’ve pushed the button and said the phone number or stored name you’d like to contact, OnStar will connect you.

With the OnStar RemoteLink mobile app, you’ll be able to have reliable and easy calling on the go. Simply connect to your vehicle with the mobile app and you’ll be able to control certain features of your vehicle. This includes viewing real-time diagnostic information, and more.

Diagnostics

OnStar Diagnostics is a great way to know what exactly is going on with your vehicle. Diagnostic information is sent to you monthly via email reports. This ensures you know what’s going on with your vehicle in easy to understand language and images.

This feature also gives you the option to run a diagnostic report while you’re on the road. All you have to do is push a blue button and an OnStar Advisor will contact you and conduct a real-time check for you. While the diagnostic reports can be accessed at any time, OnStar will automatically run hundreds of checks and maintenance reviews on your vehicle’s main operating systems.
