GMC Terrain: Service and Maintenance / Maintenance Schedule

Owner Checks and Services

At Each Fuel Stop

• Check the engine oil level. See Engine Oil.

Once a Month

• Check the tire inflation pressures. See Tire Pressure.
• Inspect the tires for wear. See Tire Inspection.
• Check the windshield washer fluid level. See Washer Fluid.

Engine Oil Change

When the CHANGE ENGINE OIL SOON message displays, have the engine oil and filter changed within the next 1 000 km/600 mi. If driven under the best conditions, the engine oil life system may not indicate the need for vehicle service for up to a year. The engine oil and filter must be changed at least once a year and the oil life system must be reset. Your trained dealer technician can perform this work. If the engine oil life system is reset accidentally, service the vehicle within 5 000 km/3,000 mi since the last service. Reset the oil life system when the oil is changed. See Engine Oil Life System.

On vehicles with diesel engines, it is recommended to drain the diesel fuel filter of water when the oil is changed or when the WATER IN FUEL CONTACT SERVICE message displays.

Air Conditioning Desiccant (Replace Every Seven Years)

The air conditioning system requires maintenance every seven years. This service requires replacement of the desiccant to help the longevity and efficient operation of the air conditioning system. This service can be complex. See your dealer.
