GMC Terrain: Vehicle Checks / Battery - North America
The original equipment battery is maintenance free. Do not remove the cap and do not add fluid.
Refer to the replacement number shown on the original battery label when a new battery is needed. See Engine Compartment Overview for battery location.
For replacement of the battery, see your dealer.
The vehicle has an Absorbed Glass Mat (AGM) 12-volt battery. Installation of a standard 12-volt battery will result in reduced 12-volt battery life.
