GMC Terrain: Vehicle Checks / Doing Your Own Service Work

It can be dangerous to work on your vehicle if you do not have the proper knowledge, service manual, tools, or parts. Always follow owner’s manual procedures and consult the service manual for your vehicle before doing any service work.
If doing some of your own service work, use the proper service manual. It tells you much more about how to service the vehicle than this manual can. To order the proper service manual, see Publication Ordering Information.
This vehicle has an airbag system. Before attempting to do your own service work, see Servicing the Airbag-Equipped Vehicle.
If equipped with remote vehicle start, open the hood before performing any service work to prevent remote starting the vehicle accidentally. See Remote Vehicle.
