Air Filter
Cabin Air Filtration
A particle filter cleans dust, soot, pol‐
len, and spores from the cabin air.
Active Carbon Filter
In addition to the particle filter, the ac‐
tive carbon filter reduces odors.
Filter service must be performed dur‐
ing regular service intervals.
Air Conditioning Regular
Operation
In order to ensure continuous efficient
performance, the air conditioning
must be run for a few minutes each
month, regardless of the weather and
time of year. The vehicle cannot be
operated with the air conditioning on
when the outside temperature is too
low.
General hints
Clear away any ice, snow, or leaves
from the air intake at the base of the
windshield; these could block the flow
of air into the vehicle.
Keep the path under the front seats
free of objects to help circulate the air
inside the vehicle more effectively.
Keep all vents open whenever possi‐
ble for best system performance.
Use of non-Saab approved hood de‐
flectors can adversely affect the per‐
formance of the system.
Service
For optimal cooling performance, it is
recommended you check the climate
control system each year, starting
three years after initial vehicle regis‐
tration, including:
■ Functionality and pressure test
■ Heating functionality
■ Leakage check
■ Check of drive belts
■ Clean condenser and evaporator
drainage
■ Performance check
