Operation Tips

Clear away any ice, snow, or leaves from the
air inlets at the base of the windshield that
could block the ow of air into your vehicle.
Use of non-GM approved hood deectors can
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside the
vehicle better.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of
the pollen from the air entering your vehicle. Like
your vehicle’s engine air cleaner/lter, it may need
to be changed periodically. For how often to change
the passenger compartment air lter, see
Scheduled Maintenance on page 442.
The access panel for the passenger compartment
air lter is located under the hood near the
windshield, on the passenger’s side of the vehicle.
