Passenger Compartment Air Filter - Buick 2007 Terraza Owner's Manual

Rear Air Outlets
The outlet behind the left rear seat is the cold
air return outlet. Be sure to keep it free from
obstructions. Also, keep the area around the base
of the center instrument panel console, between
and under the front seats, free of objects that could
also obstruct airflow to the rear seating area.
For more information on how to use the main
climate control system, see Dual Climate Control
System on page 197. For information on
ventilation, see Outlet Adjustment on page 200.

Passenger Compartment Air Filter

Passenger compartment air, both outside and
recirculated air, is routed through a passenger
compartment filter. The filter removes most
particles from the air, including dust particles.
Reductions in airflow, which may occur more
quickly in dusty areas, indicate that the filter
needs to be replaced early. For how often to
change the air filter, see Scheduled Maintenance
on page 509.
The access panel for the passenger compartment
air filter is located in the back of the glove box.
To replace the filter, do the following:
1. Pull the tab located on the outer access
panel up and out.
