Push your blue OnStar button in your vehicle to activate, change or renew services anytime. If you are enrolled in a trial plan, your paid OnStar service plan will be added to the time remaining in the trial.

If at any time you wish to cancel your OnStar service, push your blue OnStar button to speak with an Advisor or call 1.888.4ONSTAR (1.888.466.7827). If you let your service plan expire or choose to cancel it, your OnStar system will be deactivated. All services — including Automatic Crash Response and Emergency Services — will be shut off. Your vehicle won’t be able to connect with us for help, even in a crash.

You may transfer your OnStar service plan if:

• You have an active, customer-paid OnStar service plan and account.
• The primary driver does not change.
• The new vehicle is equipped with OnStar hardware.

If you still own the vehicle listed on your service plan, the plan cannot be switched to a different driver. Any service plan included with your vehicle purchase remains with the vehicle if it is sold or traded in with an active OnStar trial.
