open for a few minutes to allow outside air to circulate
into the heated interior. This results in quicker cooling
by the air conditioner. Keep the windows closed during
the operation of the air conditioner for maximum cool- ing efficiency. T
Lubrication oil circulation in the refrigerant cir-
cuit
Operate the air conditioner compressor at a low en-
gine speed (at idle or low driving speeds) a few min-
utes each month during the off-season to circulate its
oil. T Checking air conditioning system before sum-
mer season
Check the air conditioner unit for refrigerant leaks,
hose conditions, and pro per operation each spring.
This check is best performed by your SUBARU dealer. T Cooling and dehumidifying in high humidity
and low temperature weather condition
Under certain weather conditions (high relative humid-
ity, low temperatures, etc. ) a small amount of water
vapor emission from the ai r outlets may be noticed.
This condition is normal and does not indicate any
problem with the air conditioning system. T
Air conditioner compressor shut-off when en-
gine is heavily loaded
To improve acceleration and gas mileage, the air con-
ditioner compressor is designed to temporarily shut off
during air conditioner operation whenever the acceler-
ator is fully depressed such as during rapid accelera-
tion or when driving on a steep upgrade. T Refrigerant for your climate control system
Your air conditioner uses ozone friendly refrigerant
HFC134a. Therefore, the me thod 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.

API Service label
1) Indicates the oil quality by API designations
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil
has fuel saving capabilities
In choosing an oil, you want the proper quality and vis-
cosity, as well as one that will add to fuel economy.
The following table lists the recommended viscosities
and applicable temperatures.
When adding oil, different brands may be used togeth-
er as long as they are the same API classification and
SAE viscosity as those recommended by SUBARU. SAE viscosity No. and applicable temperature
*: 5W-30 is preferred.
Engine oil viscosity (thickness) affects fuel economy.
Oils of lower viscosity pr ovide better fuel economy.
However, in hot weather, oil of higher viscosity is re-
quired to properly lubricate the engine. „ Recommended grade and viscosity

„ Oil grade and viscosityIf the vehicle is used in desert areas, in areas with very
high temperatures, or used for heavy-duty applica-
tions such as towing a trailer, use of oil with the follow-
ing grade and viscosities is recommended.

Cooling systemCooling system
Never attempt to remove the radiator cap until
the engine has been shut off and has cooled
down completely. Since the coolant is under
pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap is re-
moved.
yThe cooling system has been filled at the fac-
tory with a high quality, corrosion-inhibiting,
year-around coolant which provides protection
against freezing down to –33 °F (–36 °C). For
adding, use genuine SUBARU coolant or an
equivalent: a mixture of 50% soft water and 50%
ethylene-glycol basis coolant. Use of improper
coolants may result in corrosion in the cooling
system. It is important to maintain protection
against freezing and corrosion, even if freezing
temperatures are not expected. Never mix dif-
ferent kinds of coolant. y Do not splash the engine coolant over paint-

1. Park the vehicle on a level surface and stop the en-
gine.
2. Pull out the dipstick, wipe it clean, and insert it
again. 1) Upper level
2) Lower level
3. Pull out the dipstick again and check the oil level on
it. If it is below the lower level, add oil through the dip-
stick hole to bring the level up to the upper level.
Be careful not to spill manual transmission oil
when adding it. If oil touches the exhaust pipe,
it may cause a bad smell, smoke, and/or a fire.
If oil gets on the exhaust pipe, be sure to wipe
it off.

use. Removal of the rear differential protector is not re-
quired when checking the oil level.

use only clean fluid, and be careful not to allow
any dirt into the tank . And never use different
brands together. y Avoid spilling fluid when adding it in the tank.
y Be careful not to spill power steering fluid
when adding it. If power steering fluid touches
the exhaust pipe, it may cause a bad smell,
smoke, and/or a fire. If power steering fluid gets
on the exhaust pipe, be sure to wipe it off.
The power steering fluid expands greatly as its tem-
perature rises; the fluid level differs according to fluid
temperature. Theref ore, the reservoir tank has two dif-
ferent checking ranges for hot and cold fluids.
Check the power steering fluid level monthly.
1. Park the vehicle on a level surface, and stop the en-
gine. 1) Specified range
2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has been run:
Check that the oil level is between “HOT MIN” and
“HOT MAX” on the surface of the reservoir tank.
When the fluid is cool before the vehicle is run: Check
that the oil level is between “COLD MIN” and “COLD
MAX” on the surface of the reservoir tank.
3. If the fluid level is lower than the applicable “MIN”
line, add the recommended fluid as necessary to bring
the level between the “MIN” and “MAX” line.
If the fluid level is extreme low, it may indicate possible
leakage. Consult your SUBARU dealer for an inspec-
