The Guardian app provides key OnStar safety services right on your smartphone, including:
The app also lets you invite up to seven loved ones to the "My Family" group. Everyone gets the safety services within the app as well as Location Status, which includes:
By using the sensors in your smartphone, including the accelerometer, the app can detect when you are in a moving vehicle. When a crash is detected on an Android device, the app can automatically connect you with an OnStar Emergency-Certified Advisor, who can contact First Responders and your Emergency Contact. When a crash is detected on an Apple® device, the app alerts an OnStar Emergency-Certified Advisor, who will then call your smartphone, requiring someone in the vehicle to answer the call. Advisors can also contact First Responders and your Emergency Contact.
Enabling location permissions within the app allow an OnStar Advisor to identify your smartphone’s location and contact First Responders for help, even if you can't ask for it.

The OnStar Guardian app, which is intended for use in vehicles only, uses sensors in your smartphone to determine if the smartphone is in a moving vehicle before it begins scanning to detect a crash event. The OnStar Guardian app then alerts an OnStar Emergency-Certified Advisor, who will call your phone and contact First Responders. Automatic Crash Response is a service that is embedded into your vehicle, utilizing built-in sensors to detect a crash and alert an Emergency-Certified Advisor. The in-vehicle Automatic Crash Response is available in any properly-equipped GM vehicle, while the OnStar Guardian app extends this service to any vehicle you drive, ride in or share.
Mobile Crash Response services are intended for use in vehicles only and can connect to an Advisor automatically on Android devices only. Service availability, features and functionality may vary by device and software.
Once you’re logged into the Guardian app, it will remain active and functional until you log out, even if you close the app or when it’s running in the background.
If you don't see notifications during your drive, you must enable notifications for the Guardian app in the system preferences on your device once the vehicle is parked.
If this action doesn’t resolve your concerns, please contact OnStar Technical Support at 1.877.558.8352. Please note that several device and app permissions are necessary for the Guardian app to properly function.
No. The OnStar Guardian app is a new app that gives you access to critical OnStar safety services through your smartphone in any vehicle and virtually anywhere you or your loved ones go.
The Guardian app is designed to use your smartphone’s sensors to detect a crash and alert an OnStar Emergency-Certified Advisor. The Advisor will call your phone and contact First Responders and provide them with your location. For Android users, the app can automatically connect to an Advisor even if you can't reach your phone.
If you have an emergency and have not been connected to an OnStar Emergency-Certified Advisor, you should always call 911 directly. If you are unsure how to proceed, you can connect to OnStar using the red Emergency button in the OnStar Guardian app.
Dialing 911 while you’re connected to an OnStar Advisor via the Guardian app may result in two calls being placed to 911 at the same time. This could cause confusion or a delayed response.
When a crash is detected, you will receive an automatic OnStar Guardian app notification on your smartphone. For Android devices, the notification will read: Connecting to an OnStar Emergency Advisor. A crash has been detected. For Apple devices, the notification will read: Crash detected. OnStar Emergency has been alerted. Additionally, on Android devices, you will hear an audible prompt notifying you that you are being automatically connected to an OnStar Emergency-Certified Advisor. On Apple devices, you will receive a call from the OnStar Advisor that you must answer.
Roadside Assistance provides you and any “My Family” member with help in any vehicle in which you're traveling. Services include assistance when you need a jump start, have a flat tire, are locked out or run out of gas. Towing is also available at an additional cost. Pricing for towing will vary by your location and distance of the tow.
Yes. If you are an OnStar Member, you and any "My Family" member can get help using the Guardian app in any vehicle in which you are traveling.
No. Members of “My Family” must have the app on their smartphone in order to get Roadside Assistance.
With the Guardian app, you and members of “My Family” can request Roadside Assistance while you’re traveling in any vehicle. Towing requests made through the Guardian app are an additional cost.
Roadside Assistance provided as part of the OnStar Safety & Security Plan is for a specific vehicle. Towing is included for that specific vehicle, when needed.
In your Guardian app, tap the Roadside icon on the home screen. This will connect you with an Advisor who will help find a local service provider to dispatch Roadside Assistance to your smartphone’s location.
OnStar Emergency-Certified Advisors can provide critical medical instructions in the event of an emergency. Our Advisors are trained by the International Academies of Emergency Dispatch® to handle situations such as shortness of breath, cuts, concussions, childbirth and other emergencies before help arrives.
Using the red Emergency button within the Guardian app, you can connect to an OnStar Emergency-Certified Advisor for assistance for yourself or on someone else’s behalf.
Should you encounter an emergency requiring law enforcement, EMS, fire or other emergency services, always call 911 first.
You can always push the blue OnStar button if you need help. An OnStar Advisor can assess your request and get you the right help. You can also push the blue OnStar button if you have questions about your account or the app. For an emergency situation, such as medical, push the red Emergency button.
Within the OnStar Guardian app, you can view and share device location information with members of “My Family.” Each member of “My Family” is visible by all other members of “My Family” on a map, and their location updates are visible.
Additionally, in an emergency, this feature allows an OnStar Emergency-Certified Advisor to identify your smartphone’s location and contact First Responders, even if you can’t ask for it.
Location accuracy is dependent on a number of factors, including your smartphone’s sensors, device permissions and operating system; your cellular service and connection to Wi-Fi; and overall interference from nearby buildings.
The only time an OnStar Advisor accesses your smartphone location and information from you or members of "My Family" is during an active OnStar Guardian app call. Your smartphone’s location information is shared with members of “My Family” via the Guardian app. Your smartphone’s location information is only shared with third parties (e.g., 911 dispatch centers, First Responders) when they are contacted to respond on scene.
OnStar takes protecting information very seriously. We maintain reasonable and adequate technical, administrative, and physical security and confidentiality measures designed to help protect your information from unauthorized access or acquisition. Consult the OnStar Guardian App Privacy Statement for more information.
Yes. OnStar uses your smartphone's location to identify the correct 911 dispatch center. First Responders are then sent to this location during an emergency.
If you don’t want other members of “My Family” to see your smartphone’s location, you can turn off “Location Sharing” in the Guardian app’s settings. By doing this, OnStar Advisors can still identify your smartphone’s location and contact First Responders, but members of “My Family” would not see it.
However, you should ensure Location Services on your smartphone’s device settings are set to “Always Allow” for the Guardian app. If these are not enabled, the Guardian app will not function properly.
You can use the OnStar Guardian app to invite up to seven people to join and be a part of your “My Family” group in the app. Each member of “My Family” receives all the app benefits at no cost to them, including Mobile Crash Response, Roadside Assistance, Location Status and Emergency Services.
To invite someone to “My Family,” navigate to the “My Family” section of the app menu and select the option to add a new member. A unique code is generated for your group that can be shared using your operating system’s sharing feature, such as sending through an SMS or via email. The same code can be shared with up to all seven people in the group, but it is only valid for 48 hours. A new code is generated if you select the sharing option at a later time.
An invitee should follow these steps:
1. Download the Guardian app on the App Store or Google Play.
2 Select the option indicating to “join with code.”
3. Enter the six-character code provided by the person who sent the invitation.
4. Proceed through the profile and app setup process:
• Enter your name and email address
• Create a password
• Accept terms
• Confirm email address
• Mobile phone verification
• Grant permissions
Yes. Each member of “My Family” must download the app to their individual smartphone in order to enjoy the Guardian app’s benefits and services.
Each person invited to “My Family” must create their own unique username and password for the app on their compatible smartphone. Members of “My Family” should not share credentials.
The OnStar Member will have the designation of “Family Manager,” which provides the administrative ability to add or delete people from “My Family.” This designation can be extended by the OnStar Member to any or all other members of “My Family.” However, only the OnStar Member will have rights to purchase, amend or cancel an OnStar plan.
You may leave a “My Family” group at any time by clicking on the three-dot display next to your name on the “My Family” screen and selecting the option to leave the group.
