GMC Terrain: Climate Controls / Air Vents

Use the louvers located on the air vents to change the direction of the airflow.

To open or close off the airflow:

• On the center air vents, move the slider knobs up or down.
• On the outer and rear air vents, move the slider knobs right or left.

Operation Tips

• Clear away any ice, snow, or leaves from air inlets at the base of the windshield that could block the flow of air into the vehicle.
• Clear snow off the hood to improve visibility and help decrease moisture drawn into the vehicle, which may improve long term system performance.
• Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively.
• Use of non-GM approved hood deflectors can adversely affect the performance of the system. Check with your dealer before adding equipment to the outside of the vehicle.
• Do not attach any devices to the air vent slats. This restricts airflow and may cause damage to the air vents.
