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.
When using a 12-volt battery charger on the 12-volt AGM battery, some chargers have an AGM battery setting on the charger. If available, use the AGM setting on the charger, to limit charge voltage to 14.8 volts. Follow the charger manufacturer's instructions.
Stop/Start System
The vehicle has a Stop/Start system to shut off the engine to help conserve fuel. See Starting the Engine.
