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.
.
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.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter traps most of the dust and
pollen from the air entering the
vehicle. The filter will need to be
changed periodically. See
Maintenance Schedule on
page 11‑3.
Using the climate control system
without the passenger air filter
installed could let water or other
debris enter the system. This could
cause a water leak or noises. Make
sure a new air filter is installed after
removing the old one.
The passenger compartment air
filter is under the hood below the
windshield wiper arm and the
screen on the passenger side of the
vehicle. See Engine Compartment
Overview on page 10‑5 for more
information on location.
