Call 1.888.4.ONSTAR (1.888.466.7827) with your OnStar account number or Vehicle Identification Number (VIN). You'll also need the date the vehicle was sold, traded, or "totaled."

OnStar's Refund Policy
Subscribers who request service cancellation will receive a refund for charges made within the previous 30 days. Hands-Free Calling purchases are non-refundable.

OnStar Basic Plan
Available on all OnStar-equipped model year 2015 GM vehicles in the US, the OnStar Basic Plan allows you to access certain services for five years, (beginning on the date the retail vehicle was delivered to the original customer) such as:
- RemoteLink Key Fob Services: Lock and unlock your doors, remote start your car (if equipped with factory remote start), honk your horn, and flash your lights. Not just near your car – but anywhere you have a wireless connection.
- OnStar Vehicle Diagnostics: Every month, your vehicle can run a check of your engine, transmission, antilock brakes and more and email you the results. You can relax knowing your car is checking up on its self and checking in with you on a regular basis.
- Dealer Maintenance Notification: Is it time for an oil change? A 60,000-mile checkup? You'll always know because OnStar will email your vehicle diagnostics report to the dealer, and the dealer will contact you to set up a service appointment.
Services Not Included
Without a paid OnStar plan, you will not have access to any other OnStar services such as Automatic Crash Response, Emergency Services, Crisis Assist, Stolen Vehicle Assistance, Turn-By-Turn Navigation, and OnStar Advisor support.
The five years of OnStar Basic service will begin on the date the vehicle was first purchased or leased. For example, if you buy a new Model Year 2015 vehicle equipped with OnStar, you will get the OnStar Basic Plan for five years from your delivery date, once accepting OnStar's terms and privacy statement.
If you buy a used Model Year 2015 vehicle equipped with OnStar, you are eligible for the OnStar Basic Plan services for the remaining balance of that original five-year period of time.
All OnStar-equipped Model Year 2015 GM vehicles in the U.S. are eligible for the OnStar Basic Plan, regardless of whether the vehicle is purchased or leased.
Subsequent owners of a used OnStar-equipped Model Year 2015 GM vehicle can opt-in for the remainder of the OnStar Basic Plan, if any of five-year period that starts on delivery of the vehicle to the original owner remains.

The RemoteLink mobile app is compatible with iOS® , select Android™3, BlackBerry®4 and Windows®6 devices. For a complete listing of devices, visit www.onstar.com. The list is the same for either mobile app option – RemoteLink mobile app or RemoteLink Key Fob Services.
Canceling your OnStar Basic Plan
Uninstalling the RemoteLink mobile application will not cancel the OnStar Basic Plan. To cancel the Basic Plan, please contact OnStar at 1.888.4ONSTAR. If you do not contact OnStar to cancel the Basic Plan, those services will remain available to you.

OnStar Hands-Free Calling is a voice-activated calling system built into your vehicle. Just press the Hands-Free Calling button, speak a number or saved name, and we will connect you while you stay focused on the road. You can purchase prepaid minutes online, push your blue OnStar button, or call 1.888.4.ONSTAR (1.888.466.7827).
When you purchase a new prepaid minute package, your existing minutes will rollover and be added to your purchased minutes. Purchased minutes are valid until their expiration date or when your OnStar service ends, whichever date comes first. You can also rollover any active unused minutes to a new OnStar-equipped vehicle. Just push your blue button or call 1.888.4ONSTAR (1.888.466.7827) to purchase or rollover minutes.
To check the number of minutes you have remaining, simply push the calling button. When OnStar responds with "OnStar ready," say "Minutes." When OnStar responds with "Please say verify or add," say "Verify." The system will tell you how many minutes you have left on your account.
Use of minutes
Hands-Free calling minutes are used only when you place or receive calls via the phone button, or access the Virtual Advisor for traffic, stock or other automated updates. Your minutes are never used when you push the blue OnStar or red emergency buttons, speak to an Advisor, or use Turn-by-Turn Navigation.
Receiving a call
When someone calls you in your vehicle, you will hear a ring and see the Green System Status light flashing. Simply press the phone button to answer. Press it again to end the call. Watch video
Your OnStar Hands-Free Calling number
To hear your OnStar Hands-Free Calling number, simply push the calling button in your vehicle. When you hear "OnStar ready," say "My number." If you don't hear your number, please push the blue button for an Advisor or call us at 1.888.4.ONSTAR (1.888.466.7827) and we'll provide it.
It's our policy to provide a local number for your vehicle. If you received a number that's not local, please contact us for a new local number.
If you're getting unwanted calls, you can ask an Advisor for a different Hands-Free Calling number. Please have your account number or Vehicle Identification Number (VIN) ready.
Voice Dialing Tips
If you're having trouble dialing, it may be necessary to emphasize certain sounds. Try these tips to improve dialing accuracy:
- If the system does not understand "zero", try "oh" and vice versa
- Try saying "oh" slower or faster
- On zero, emphasize "r" sound
- Emphasize the "n" sound at the end of the word
- Say the digit softer
- Emphasize the "t" sound at the beginning
The following tips may be helpful when using these commands:
- Emphasize the "l" sound to reduce confusion with the word call
- Emphasize the hard "k" sound
- When storing a number with a Nametag, use two words or two syllable words rather than one. For example "My Home" instead of "Home"
- If the system is having trouble understanding numbers when you dial, set up nametags to speed dial numbers you regularly call.

RemoteLink™ App Key Fob Services
If you have a 2014 OnStar equipped vehicle and use OnStar RemoteLink® mobile app during your OnStar trial or consecutive subscription, you'll keep access to the RemoteLink Key Fob Services (includes Remote Start, Remote Door Lock, and Remote Horn and Lights) for five years from vehicle delivery date. At this time, there are no plans to extend access to Key Fob Services to earlier model year GM vehicles.
OnStar RemoteLink Key Fob Services do not include any Emergency Services, Automatic Crash Response, Stolen Vehicle Assistance, Live Advisor Service, or Hands-Free Calling. If you sell your GM vehicle or wish to cancel use of Key Fob Services, you must contact OnStar at 1.888.4.ONSTAR. Subsequent owners will be able to activate the remaining term of the Key Fob Services by calling 1.888.4.ONSTAR (1.888.466.7827).
When RemoteLink Key Fob Services are active, location information is collected each time you use the app.
What to do if your vehicle is sold or otherwise transferred Please note it is your responsibility to notify OnStar if you sell or transfer a GM vehicle with active OnStar service, including RemoteLink Key Fob Services.

Cancelling your service cannot be done online or within the RemoteLink application.
OnStar RemoteLink® functionality for Chevrolet Volt
In addition to the RemoteLink™ app's standard capabilities, Chevrolet Volt drivers will be able to easily manage the capabilities of their electric vehicle with extended range including setting charge alerts, checking on current battery charge level and contacting a dedicated Volt advisor. For more information visit www.myvolt.com.
Remote commands for the Chevrolet Volt
The OnStar RemoteLink® mobile app will allow Volt owners to control a number of key vehicle functions and OnStar features from their mobile device. Drivers will be able to manage vehicle charging, read the state of battery charge and review vehicle history data such as odometer readings, miles per gallon and miles driven in EV mode. In addition, they will have the ability to perform traditional OnStar and key fob functionality such as door lock, unlock, and horn and lights. For more information visit www.myvolt.com.
Charge command status for the Chevrolet Volt
You will receive a message on the application when a command has been successfully sent to the vehicle. If in view of the vehicle, the dash LED will be solid when charging, flash when the charge is on delay, and blink quickly if the battery is full and the vehicle is still plugged in.
The smart grid and OnStar RemoteLink®
The OnStar RemoteLink® mobile app allows Volt drivers to manually select "grid friendly" mode. This allows the customer to select the time of day when they want their vehicle fully charged. Under typical circumstances, this would allow the vehicle to be charged at off-peak times and reduce the impact on the grid.
OnStar Turn-by-Turn Navigation provides voice-guided driving directions to you in your vehicle over your sound system, using Global Positioning System (GPS) technology to route you to your destination.
Navigation is available for all OnStar Directions & Connections subscribers traveling through our service areas. This covers approximately 98% of the U.S. population, and approximately 80% of the population in Canada.
Using Turn-by-Turn Navigation
To get directions, simply push the blue button and tell the Advisor where you want to go. Your Advisor will send detailed directions to the vehicle. These automated voice-guided directions take you to your destination with "turn tones," providing street names-and distances to each turn-along the way. The system even alerts you if you miss a turn, and gives a revised route to the destination.
Adjusting your route
You can easily modify your route with simple voice commands. Detailed instructions can be found on the Quick Reference Card in your OnStar manual.
Some popular commands:
"Cancel route" - Command to system to cancel receiving routes to a destination.
"Route preview" - Command to system to preview the route to destination.
"Repeat" - Command to the system to repeat the last maneuver.
Should you drive through an area where OnStar Turn-by-Turn Navigation is not available, push your blue button and an Advisor can provide live driving directions.
OnStar Vehicle Diagnostics
Use this valuable tool to keep tabs on vehicle maintenance. Most subscribers with OnStar-equipped 2004 model year or later vehicles are eligible for Vehicle Diagnostics at no additional charge. All you have to do is enroll.
Every month we'll send you an e-mail with information on the condition of your engine, transmission, antilock brakes, and more. Your customized report includes recommended actions to ensure proper maintenance.
Diagnostics for multiple vehicles
If you have multiple OnStar-equipped vehicles, each vehicle must be enrolled separately. You'll receive a separate email report for each one. There is no additional cost to enroll.
Make sure you receive your report
We recommend adding firstname.lastname@example.org to your address book so your diagnostics report will be accepted in your email inbox. Click here to find instructions for your specific email service provider.
Send the report to multiple addresses
We can send a Vehicle Diagnostics Report to multiple email addresses. If your GM vehicle is used by other drivers, you can ensure everyone is up-to-date on your vehicle's maintenance. To add email addresses to your account, call an Onstar Advisor at 1.888.4.ONSTAR.
If your "Check Engine" light comes on, or you have any concerns about your vehicle, just push the blue button. An Advisor can run an On-Demand Diagnostics check and tell you if there is a maintenance issue that requires your attention. There's no additonal charge for this service.
Updating your email address
If you need to change your email address, contact OnStar at 1.888.4.ONSTAR and press "2" to update personal information. Please provide the Advisor with your PIN and ask to update your email address. You can also press the blue button in your vehicle and ask an advisor to update your email address. Either way, it only takes a few minutes.
In November, 2002, the U.S. Federal Communications Commission (FCC) ruled that cellular carriers would no longer be required to support the analog cellular network as of early 2008. This ruling meant OnStar systems based solely on analog technology would not operate after 2008.
As a result, starting January 1, 2008, OnStar services in the U.S. and Canada became available only through equipment that operates on the digital network. OnStar subscribers with affected equipment were contacted about the Analog-to-Digital Transition. Vehicles manufactured prior to 2007 may have been affected by this ruling. To learn more, you can click the links below.

OnStar for hearing and speech-impaired subscribers
We offer in-vehicle TTY services, delivering OnStar services via text messages. A dial pad will also provide access to OnStar calling.
Dedicated TTY Advisor
With 24/7 connectivity to a dedicated TTY Advisor, you'll have the peace of mind of knowing that, when you need help, we can pinpoint your location and quickly contact emergency services on your behalf.
Eligible subscribers can request TTY equipment through their GM dealer. Most or all of the equipment cost can be reimbursed through the GM Mobility Reimbursement Program during the first year of ownership, subject to program rules. The use of OnStar services requires an active OnStar subscription.
OnStar TTY requires a model-year 2007 and newer vehicle purchase or lease with OnStar Generation 7.0 hardware. Please visit gmmobility.com for more information. At this time, OnStar TTY is not available in Canada because TTY is not supported by Canada's wireless carriers.
Using TTY in your vehicle
Once your TTY equipment is installed, OnStar services will be available to you based on your subscription plan (excluding OnStar Turn-by-Turn Navigation and Virtual Advisor). If you have the Directions & Connections subscription plan, driving directions and point-of-interest locations can be delivered via the TTY device. Please note, lengthy or intricate routes may be cumbersome.
Transferring TTY equipment
The TTY device may be transferred in and out of the vehicle. Damaged or misplaced equipment may prohibit communication with OnStar. Also, it is your responsibility to keep your TTY device fully charged. Please see your manufacturer's reference manual for instructions and details.
TTY in emergencies
Push the red emergency button to connect to a dedicated OnStar TTY Advisor who can locate your vehicle, find out what type of assistance you need, and call nearby emergency service providers who can dispatch appropriate emergency responders.
If you cannot answer, an OnStar Advisor will contact a nearby emergency services provider who will dispatch help to your determined location.
If you accidentallypush the red emergency button, you must disconnect within 10 seconds by pushing the phone button on the OnStar three-button system. If OnStar emergency does not receive a response, we will dispatch emergency services to your location.
You can also contact us with our dedicated TTY toll-free line, 1.877.248.2080. While email may be your primary mode of communication, it is absolutely necessary that you contact OnStar via telephone in emergency situations.
Using OnStar TTY to make phone calls
OnStar-equipped vehicles can make and receive TTY phone calls through the dealer-installed dial pad. For safety, this service is not available when your vehicle is moving. When you are in TTY mode, the phone button on the three-button OnStar system is disabled. To make calls, you must use the dealer-installed dial pad. OnStar's Shared Minutes plans are currently not available with the TTY system.
TTY to redial a call
Push the phone button on the dial pad to redial the last number dialed or received. Refer to the TTY manufacturer's owner's guide for details on functionality of the TTY device.
TTY to receive a call
When the vehicle is not moving, the green status light on the OnStar TTY Interface Module will blink when you receive an incoming personal call. To answer, push the phone button on the dial pad.
To call to another TTY user from your vehicle, you can dial direct using the dial pad provided. If you would like to make a personal call from your vehicle to a non-TTY user, you must use the relay service. You will not need the relay service to communicate with OnStar TTY Advisors, as they have TTY capability.
Ending a TTY call
If you are communicating with an OnStar TTY Advisor through the blue button, the Advisor will disconnect the call after your conversation ends. If you are on a personal phone call, use the phone button on the dial pad to end the call.
OnStar TTY when driving
OnStar services are meant to complement your driving experience while keeping you safe and protected. As a result, in order to maintain a safe driving environment, OnStar TTY services will work only when your vehicle is not moving. However, your red emergency button is always active.
OnStar TTY troubleshooting
Your TTY device is manufactured by an independent manufacturer and is covered by the manufacturer's warranty; it is not covered under the GM new vehicle limited warranty. All other parts are covered by the standard parts and labor warranty of your new vehicle.
If you are having problems with your TTY, make sure the status light next to your three-button OnStar system (located either in your rearview mirror or in your overhead console) is green.
- status light is not green-your vehicle's ignition turn off and then on. If the status light next to the three-button system does not illuminate, this may indicate a problem with your OnStar system.
- LEDs not illuminated-check that the TTY device is properly plugged in. Re-plug it into the TTY jack, and ensure the OTIM is set to TTY mode by pushing the mode button until the mode LED illuminates. If the lights are still not illuminated, please call OnStar via the TTY toll-free number, 877.248.2080 or visit your GM dealer.
- Garbled text -make sure the TTY device is fully charged. If it is fully charged, cellular connectivity issues may be affecting your call. In that case, please disconnect your call and try again in a few minutes.
TTY status lights
- Green: Your TTY system in the vehicle is ON and is ready to make or receive calls.
- Blinking Green: A call is in progress or there's an incoming personal call.
- Red: Your TTY device may not be functioning properly. Push the OnStar button to attempt to contact an OnStar Advisor for assistance. If you cannot contact us, please take your vehicle to your nearby GM dealership as soon as possible for diagnosis of the system.
