The crossover SUV GMC Terrain was designed as a replacement for the Pontiac Torrent after the brand was discontinued due to GMC restructuring.
The 2020 GMC Terrain owner's manual on this page opens up with an introduction then moves into the keys, doors and windows to ensure you can safely get in and out of the car.
The following chapters on seats and storage are not just for comfort but also for the safety of those inside the vehicle.
Next up the "Instruments and Controls" parts of the guide will show you what the warning lights that may be appearing in your Terrain are trying to tell you.
The latter part of the manual focuses on maintenance and caring for your car. Information such as tyre pressures and oil types are mentioned here along with what battery size to buy as a replacement.
