Air Conditioner Compressor Shut-Off When Engine Is Heavily Loaded; Refrigerant For Your Climate Control System; Air Filtration System (If Equipped); Replacing An Air Filter - Subaru 2008 Impreza Owner's Manual

& Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steep
upgrade.
& Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od of adding, changing or checking the
refrigerant is different from the method for
CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are
not covered under warranty.
Air filtration system (if
equipped)
If your vehicle's air conditioning system is
equipped with an air filtration system,
replace the filter element according to
the replacement schedule as follows. This
schedule should be followed to maintain
the filter's dust collection ability. Under
extremely dusty conditions, the filter
should be replaced more frequently. It is
recommended that you have your filter
checked or replaced by your SUBARU
dealer. For replacement, use only a
genuine SUBARU air filter kit.
Replacement schedule:
Every 12 months or 7,500 miles (12,000
km) whichever comes first
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter:
– Reduction of the air flow through
the vents.
– Windshield gets easily fogged or
misted.
Climate control
NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained.
