3 Months of added peace of mind—No added cost:
- Emergency services, your priority link to a live Advisor, 24/7
- Automatic Crash Response that can automatically alert an Advisor when your air bags deploy so help can be sent to your exact location. On most newer models, built-in crash sensors can also automatically alert OnStar, even if your airbags do not deploy, and send critical crash details.
- OnStar Vehicle Diagnostics3, an exclusive remote diagnostic check that sends you detailed e-mail results every month
- Even when you only kind of know where you're going, be sure you'll get there. Take advantage of built-in Turn-by-Turn Navigation4 and enjoy the convenience of voice-guided directions at the push of a button.
