Buick 2006 Lucerne - Manual (Page 155)

Outlet Adjustment
Use the levers located in the middle of the front outlets
to change the direction of the airflow and use the
shutoff wheels to adjust the amount of airflow.
You can adjust the rear seat outlet direction of the
airflow using the lever in the center of each outlet.
Operation Tips
• Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
• Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
• Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
Passenger Compartment Air Filter
The passenger compartment air filter traps most of the
pollen from the air entering your vehicle. Like your
vehicle’s engine air cleaner/filter, it may need to
be changed periodically. For how often to change the
passenger compartment air filter, see Scheduled
Maintenance on page 6-4.
The access panel for the passenger compartment air
filter is located under the hood near the windshield,
on the passenger’s side of the vehicle.
