Cooling and dehumidifying in high humidity and low temperatureweather conditions
Under certain weather conditions (high relative hu-
midity, low temperatures, etc.) a small amount of wa-
ter vapor emission from the air outlets may be not-
iced. This condition is normal and does not indicate
any problem with the air conditioning system. 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 conditioner operation whenever
the accelerator is fully depressed such as duringrapid acceleration or when driving on a steepupgrade. Refrigerant for your climate control system
Your air conditioner uses ozone friendly refrigerant
HFC134a. Therefore, the method of adding, chang-
ing 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.

– CONTINUED –
Never turn off the ignition switch while the vehicle
is moving. Keep your engine tuned-up. If you feel the engine
running rough (misfiring, backfiring or incomplete
combustion), have your vehicle checked and re-
paired by an authorized SUBARU dealer. Do not apply undercoating or rust prevention
treatment to the heat shield of catalytic converter and the exhaust system.
WARNING
Avoid fire hazards. Do not drive or park the
vehicle anywhere near flammable materials
(e.g. grass, paper, rags or leaves), becausethe catalytic converter operates at very hightemperatures. Keep everyone and flammable materials
away from the exhaust pipe while the engine is running. The exhaust gas is very hot. Periodic inspections
To keep your vehicle in the best condition at all
times, always have the recommended maintenance
services listed in the maintenance schedule in the“
Warranty and Maintenance Booklet ” performed at
the specified time or mileage intervals.
