heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is de-
signed to temporarily shut off during air
conditioner operation whenever the accel-
erator 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
method 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 re-
frigerant are not covered under warranty.
Air filtration system
If your vehicle ’s air conditioning system is
equipped with an air filtration system, re-
place the filter element according to the
replacement schedule shown in the fol-
lowing. This schedule should be followed
to maintain the filter ’s dust collection abili-
ty. Under extremely dusty conditions, the
filter should be replaced more frequently.
It is recommended that you have your fil-
ter checked or replaced by your SUBARU
dealer. For replacement, use only a genu-
ine SUBARU air filter kit.
Replacement schedule:
Every 12 months or 7,500 miles (12,000

face of the rear window glass.

FM reception
Although FM is normally static free, recep-
tion can be affected by the surrounding ar-
ea, atmospheric conditions, station
strength and transmitter distance. Build-
ings or other obstructions may cause mo-
mentary static, flutter or station interfer-
ence. If reception continues to be unsatis-
factory, switch to a stronger station.
Installation of accessories
Always consult your SUBARU dealer be-
fore installing a citizen band radio or other
transmitting device in your vehicle. Such
devices may cause the electronic control
system to malfunction if they are incorrect-
ly installed or if they are not suited for the
vehicle.
Do not use sharp instruments or
window cleaner containing abra-
sives to clean the inner surface of
the window on which the antenna is
printed. Doing so may damage the
antenna printed on the window.
