The VDC warning light does not come on when the
ignition switch is turned to the “ON” position. y The VDC warning light remains on after the engine
has started and stays lit even when the vehicle speed
reaches about 8 mph (12 km/h).y The VDC warning light comes on while the vehicle
is running.y If the electrical circuit of the VDC system itself be-
comes faulty, the VDC warning light only comes on. At
this time, the ABS (Anti-lock Brake System) remains
fully operational.y The warning light comes on when the electronic
control system of the ABS/VDC system becomesfaulty.
The VDC system provides its ABS control through the
electrical circuit of the ABS system. Accordingly, if the ABS is inoperative, the VDC system also becomes un-
able to provide ABS control. As a result, the VDC sys-
tem becomes inoperative, causing the VDC warning
light to come on. Though both the VDC and ABS sys-
tems are inoperative in this case, the ordinary func-
tions of the brake system are still available. You will be
safe while driving with this condition, but you should
have your vehicle checked at a SUBARU dealer as
soon as possible.NOTE
If the warning light behavior is as described be-
low, the VDC system may be considered normal.y The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off.y The warning light remains on after the engine
has been started, but it goes out when the vehicle
speed reaches 8 mph about (12 km/h).y The warning light comes on during driving, but
it goes out immediately and remains off. „ Brake system warning light
yDriving with the brake system warning light
on is dangerous. This indicates your brake sys-
tem may not be working properly. If the light re-
mains on, have the brakes inspected by a
SUBARU dealer immediately. y If at all in doubt about whether the brakes are
operating properly, do not drive the vehicle.
Have your vehicle towed to the nearest
SUBARU dealer for repair.

ter the engine has started. y It comes on when the VDC system is deactivated
(by operating “VDC OFF” switch or in the standby state).
NOTE y The light may stay on for a while after the engine
has been started, especially in cold weather. This
does not indicate the existence of a problem. The
light should go out as soon as the engine has warmed up.y
The “VDC OFF” indicator light comes on when
the engine has developed a problem and the
CHECK ENGINE warning light is on.
The VDC system is probably faulty under any of the
following conditions. Have your vehicle checked at a
SUBARU dealer as soon as possible. y The VDC OFF indicator light does not come on
when the ignition switch is turned to the “ON” position. y The light does not go out even after several minutes
have passed (the engine has warmed up) after the en-
gine has been started. „ Security system status indicator
light (if equipped)
This light is found at the bottom center of the combina-
tion meter panel.
On vehicles equipped with a security system, it blinks
to show the driver the operational status of the security

3. Set the fan speed control dial at the highest speed. Automatic climate control system (if
equipped)
NOTE y
Operate the automatic climate control system
when the engine is running. y When the engine coolant is cold, for instance in
cold weather, the air flows through the windshield
defroster outlets and the blower runs at the lowest
speed to prevent cold air from blowing directly
against the driver and front passenger.y In the “AUTO” mode, if the air temperature in the
passenger compartment is cooled down to the
specified temperature, the air conditioner com-
pressor stops automatically. For efficient defog-
ging or dehumidifying in cold weather, press the
“A/C” switch on.y Even when cooling is not necessary, setting the
temperature much lower than the current outlet air
temperature turns on the air conditioner compres-
sor automatically and the “A/C” indicator light on
the control panel comes on.
The automatic climate control system automatically
controls outlet air temperature, fan speed, air flow dis-
tribution air-inlet control, and air conditioner compres-
sor operation. It activates when the “AUTO” switch is

“OUT.TEMP” switch. The outside air temperature will
be displayed for five seconds, and then the display au-
tomatically changes back to the inside air tempera- ture.
The display changes over from the inside air tempera-
ture to the outside air temperature as its normal indi-
cation if you keep the switch pressed for more than 2seconds.
NOTE y The outside air temperature display shows the
outside air temperature in a range from –22 to
131 °F (–30 to 55 °C).
y You can check the outside air temperature even
when the Automatic Climate Control is off. (The ig-
nition switch should be in the “ON” position.) y In the following cases, the display can indicate a
higher temperature than the actual outside air
temperature: – In direct sunlight
– When the vehicle is parked for a long period of
time with the engine kept running.
– During stop and go driving
T – Defroster switch

Efficient cooling after parking in direct
sunlight
After parking in direct sunlight, drive with the windows
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. „ Lubrication oil circulation in the refrig-
erant circuit
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. „ Checking air conditioning system be-
fore summer season
Check the air conditioner unit for refrigerant leaks,
hose conditions, and proper operation each spring.
This check is best performed by your SUBARU dealer. „
Cooling and dehumidifying in high hu-
midity 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 air outlets may be noticed.
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 con-
ditioner compressor is designed to temporarily shut off
during air conditioner operation whenever the acceler-
ator is fully depressed such as during rapid accerela-
tion 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
refrigerant are not covered under warranty.
