OnStar Advisors are also required to announce their presence immediately once they have established voice communication into a vehicle. View our privacy statement here.

Services Included

All model year 2014 GM vehicles have access to limited OnStar RemoteLink® Mobile App services.

Depending on the vehicle’s model year, Basic Plan services may include:

  • Limited OnStar RemoteLink® Mobile App Services: Lock and unlock your doors, remote start your vehicle (if equipped with factory remote start), honk your horn, and flash your lights. Not just near your vehicle – but anywhere you have a wireless connection. (MY 2014 and newer)
  • A monthly OnStar Diagnostics Report8: 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 vehicle is checking up on itself and updating you on a regular basis. (MY 2015 and newer)
  • 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. (MY 2015 and newer)
  • OnStar Destination Download: Never get lost again. Send directions to your in-vehicle navigation screen from your smartphone via your RemoteLink mobile app. (MY 2016 and newer)

Start Date

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.

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.

Hands-Free Calling quick Reference

For quick instructions at your fingertips, you can also check out our Hands-Free Calling e-booklet, featuring a printable quick guide.

Theft Alarm Notification

Theft Alarm Notification is a new feature within the Stolen Vehicle Assistance service from OnStar® available on compatible vehicles enrolled in the Security or Guidance plan.

Service plans

The Theft Alarm Notification is a new feature that is part of the Stolen Vehicle Assistance Service. This service is included in the Security and Guidance plans.

Vehicle compatibility

1. Confirm your vehicle is compatible for receiving Theft Alarm Notification by visiting or by speaking with an Advisor by pressing the blue OnStar button in your vehicle. You can also call (888) 4-ONSTAR.
2. Ensure you are enrolled in an eligible OnStar plan (Security or Guidance).
3. Set up your notification preference (e.g., phone, text message, email) for receiving Notification on or through an Advisor.
4. Every time you leave your vehicle, arm it by electronically locking your vehicle via the power door lock button, your vehicle key fob or by using the OnStar RemoteLink remote lock feature.

Unenrolling in Theft Alarm Notification

You can remove some or all your notification preferences via or through an Advisor.

Responding to a Theft Alarm Notification

If you receive a Theft Alarm Notification, you should contact OnStar® to check on the location of your vehicle. If your vehicle has been stolen or tampered with, contact local law enforcement to file a police report and let them know you have OnStar enabled. If your vehicle has been stolen, the authorities can work with OnStar to help locate your vehicle and, in some cases, use Remote Ignition Block™ or Stolen Vehicle Slowdown®, which are other features within the Stolen Vehicle Assistance service. If your alarm was accidentally triggered and there is no problem with your vehicle, we’d appreciate it if you would contact (888) 4-ONSTAR and select menu option three to report the alarm as accidental.

Responding to a stolen vehicle

If your vehicle has been stolen, contact your local law enforcement to file a police report and let them know you have OnStar enabled. The authorities can work with OnStar to help locate your vehicle and, in some cases, use Remote Ignition Block™ or Stolen Vehicle Slowdown®, which are other features within the Stolen Vehicle Assistance service. You should also contact (888) 4-ONSTAR and select menu option three to begin the Stolen Vehicle Assistance process. The OnStar advisor will ask you for the stolen vehicle report number and confirm if law enforcement is involved.

Responding to vehicle damage or property theft

Most insurance companies require a police report for vehicle damage or personal property theft. You should contact local law enforcement to file a report and then contact your insurance company. In addition, contact (888) 4-ONSTAR and select menu option three to report the incident.

Communication preference options

You can set a preference to receive Theft Alarm Notification by phone, text message or email — or all of the above. Visit to set your preferences. Standard texting rates may apply.

Setting communication preferences

To set your Theft Alarm Notification communication preferences, visit and log in to your account. You can set your Theft Alarm Notification preferences using the existing contact information on your account. You can change these preferences at any time on or through an Advisor.

Communication preference recipients

U.S. subscribers can have multiple individuals receive notifications. All recipients must be listed on the account with the necessary contact information. To add additional drivers to your account, press your blue OnStar® button or call (888) 4-ONSTAR to speak to an Advisor.

Not receiving notifications

There are a few limitations that can prevent the Theft Alarm Notification system from sending an alert, including:

  • A valid key was used to start the vehicle
  • The vehicle was towed away and is not equipped with a tilt sensor
  • The vehicle was not properly armed, meaning the doors were not electronically locked from either inside the vehicle, via the vehicle key fob or the OnStar RemoteLink mobile app
  • Your vehicle may not be equipped with the more advanced theft sensors, like glass-breakage or interior movement. You can check to see what features are available on your vehicle by visiting or by speaking with an Advisor by pressing the blue OnStar button in your vehicle. You can also call (888) 4-ONSTAR
  • You do not currently have an active OnStar Security or Guidance subscription
  • You do not currently have a preference set to receive a Theft Alarm Notification

Not receiving alerts when alarm sounds

If your alarm is sounding and you have not received an alert, you can visit and log in to your account to verify that you have an active subscription to the Security or Guidance plan and that your Theft Alarm Notification preferences are set up appropriately. You can also press your blue OnStar button or call (888) 4-ONSATR to speak to an Advisor who can check your account for you.

Receiving alerts when alarm does not sound

Some vehicles have a “key learning” theft trigger, which will not sound the vehicle alarm when activated. The “key learning” theft notification is triggered when someone has made a copy of a valid key. If you requested to have a duplicate key made, the duplication process will trigger a notification to you. If that’s not the case, you can call (888) 4-ONSTAR and select menu option three to speak to a Stolen Vehicle Advisor who can check to see what theft sensor was triggered for your notification.

Theft alarm triggers

The theft-deterrent system in your vehicle may be triggered in the following instances (optional feature across most 2014 and newer makes/models):

  • Key learning (copy of key made)
  • Forced entry alarm (door, trunk, hood)
  • Tilt/inclination
  • Interior movement
  • Charging Alarm (Electric Vehicles only)

You can check to see what features are available on your vehicle by visiting or by speaking with an Advisor by pressing the blue OnStar button in your vehicle. You can also call (888) 4-ONSTAR.

Keys used to access vehicle

If your key is used to access your vehicle, you would not receive a notification in that case. The system has no way to detect who is driving away with the real keys.

Arming vehicle correctly

For Theft Alarm Notification to be active, your vehicle must be armed, meaning it must be electronically locked via the power lock button inside the vehicle, your vehicle key fob or by using the OnStar RemoteLink® mobile app’s remote lock feature.

Turn-by-Turn Navigation

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.

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 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 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.

On-Demand Diagnostics

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.

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.

TTY equipment

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.

TTY-capable vehicles

OnStar TTY requires a model-year 2007 and newer vehicle purchase or lease with OnStar Generation 7.0 hardware. Please visit gmmobility.comfor 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.

Relay services

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.
