As the owner of a new GMC, you are automatically enrolled in the GMC Roadside Assistance
program for up to 5 years/60,000 miles, whichever occurs first, at no expense to you. GMC’s
Roadside Assistance toll-free number is staffed by a team of trained advisors who are available
24 hours a day, 365 days a year, to contact a service provider for light services (fuel delivery,
jump-starts, flat tire and lock-outs) or make arrangements to tow your vehicle to the nearest
GMCdealer for any repairs.

Roadside Assistance and OnStar

If you require roadside service and have a current OnStar service plan, press the OnStar button
and the vehicle will send your current GPS location to an OnStar Advisor who will speak to you,
assess your problem, contact Roadside Assistance and relay your exact location so you will get
the help you need.

To learn more about OnStar services, press the blue OnStar button, visit onstar.com, call
1-888-4-ONSTAR (1-888-466-7827), or refer to your Owner’s Manual.
