Outlet Adjustment; Passenger Compartment Air Filter - Chevrolet Optra 2005 Owner's Manual

Outlet Adjustment

Use the lever located in the center of each outlet to
change the direction of the airflow. For four-door models,
use the thumbwheel located next to the outlets to turn
them on and off. For five-door models, use the
thumbwheel located below the outlets to turn them
on and off.
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

Your vehicle may have a passenger compartment
air filter. It is located on the passenger side under the
glove box.
The filter traps most of the pollen from air entering the
module. Like your engine's air cleaner/filter, it may need
to be changed periodically.
