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 shown below, the VDC system may be considered normal.The warning light comes on right after the engine is started but
goes out immediately, remaining off. The warning light remains on after the engine has been started,
but it goes out when the vehicle speed reaches 8 mph about (12km/h). The warning light comes on during driving, but it goes out im-
mediately and remains off. Brake system warning light
WARNING
Driving with the brake system warning light on is dangerous.
This indicates your brake system may not be working properly. If the light remains on, have the brakes inspected by a SUBARU
dealer immediately. If at all in doubt about whether the brakes are operating prop-
erly, do not drive the vehicle. Have your vehicle towed to the
nearest SUBARU dealer for repair.
This light has the following two functions: Parking brake warning
The light comes on with the parking brake applied while the ignition switch is in the “ON” position. It goes out when the parking brake is
fully released. Brake fluid level warning
This light comes on when the brake fluid level has dropped to near the “MIN” level of the brake fluid reservoir with the ignition switch in
the “ON” position and with the parking brake fully released.
If the brake system warning light should come on while driving (with
the parking brake fully released and with the ignition switch posi- (U.S.)

VDC (Vehicle Dynamics Control) OFF indicator light (if equipped)
This indicator light comes on when the ignition switch is turned ON
and goes out about 6 seconds after the engine has started. It comes on when the VDC system is deactivated (by operating “VDC
OFF” switch or in the standby state).
NOTE The light may stay on for a while after the engine has been
started, especially in cold weather. This does not indicate the exis- tence of a problem. The light should go out as soon as the enginehas warmed up. The “VDC OFF ” indicator light comes on when the engine has de-
veloped 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. The VDC OFF indicator light does not come on when the ignition
switch is turned to the “ON” position.
The light does not go out even after several minutes have passed (the
engine has warmed up) after the engine has been started. Security system status indicator light (if equipped)
This light is found at the bottom center of the combination meter panel. On vehicles equipped with a security system, it blinks to show the driver
the operational status of the security system. For detailed information, re-fer to the “Security system ” in Chapter 2.
Shift position indicator (for AT vehicles)
This indicator shows the position of the shift lever. Turn signal indicator lights
These lights show the operation of the turn signal or lane change signal.
If the indicator lights do not blink or blink rapidly, the turn signal bulb
may be burned out. Replace the bulb as soon as possible. Refer to the

nOUT.TEMP switch
To check the outside air temperature, push the “OUT.TEMP” switch.
The outside air temperature will be displayed for five seconds, and
then the display automatically changes back to the inside air temper-
ature.
The display changes over from the inside air temperature to the out-
side air temperature as its normal indication if you keep the switch
pressed for more than 2 seconds. NOTE You can check the outside air temperature even when the Au-
tomatic Climate Control is off. (The ignition switch should be in the “ON” position.)
In the following cases, the display can indicate a higher tem-
perature 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
n
— Defroster switch
To defrost or dehumidify the windshield and side window, push the
defroster switch “
”. When the “” switch is pushed, re-
gardless whether the air conditioner is operating or not, outside air is
drawn into the passenger compartment, the air conditioner compres-
sor turns on, air flow is directed towards the windshield and side win-dows, and the indicator light “
” on the control panel comes on.
After eliminating the fogging from the windshield, set the air condition- er back in the AUTO mode by pushing the “AUTO” switch or turn off
by pushing the “OFF” switch or “
” switch.

Operating tips for heater and air conditionerCleaning ventilator grille
HB5019BC
Always keep the front ventilator inlet grille free of snow, leaves, or oth-
er obstructions to ensure efficient heating and defrosting. Since the
condenser is located in front of the radiator, this area should be kept
clean because cooling performance is impaired by any accumulation
of insects and leaves on the condenser. 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 windowsclosed during the operation of the air conditioner for maximum cool-
ing efficiency. Lubrication oil circulation in the refrigerant circuit
Operate the air conditioner compressor at a low engine speed (at idle
or low driving speeds) a few minutes each month during the off-sea-
son to circulate its oil. Checking air conditioning system before 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 humidity and low tempera- ture weather condition
Under certain weather conditions (high relative humidity, low tempera-
tures, 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 conditioner com-
pressor is designed to temporarily shut off during air conditioner op-
eration whenever the accelerator is fully depressed such as during
rapid accerelation or when driving on a steep upgrade. Refrigerant for your climate control system
Your air conditioner uses ozone friendly refrigerant HFC134a. There-
fore, 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.
Air filtration system (if equipped) If your vehicle ’s air conditioning system is equipped with a optional air
filtration system, replace the filter element according to the replacement
schedule shown below. This schedule should be followed to maintain the
filter’ s dust collection ability. Under extremely dusty conditions, the filter
should be replaced more frequently. Since the filter element is a viscous
type, it is unnecessary to clean or wash the element. Have your filter
checked or replaced by your SUBARU dealer.
Replacement schedule: Every 12 months or 9,300 miles (15,000 km) whichever comes first
NOTE The filter can influence the air conditioning, heating and defroster performance.

State emission testing (U.S. only)
WARNING
Testing of an All-Wheel Drive vehicle must NEVER be performed
on a single two-wheel dynamometer. Attempting to do so willresult in uncontrolled vehicle movement and may cause an acci-
dent or injuries to persons nearby.
CAUTION
Resultant vehicle damage due to improper testing is not covered
under the SUBARU Limited Warranty and is the responsibility ofthe state inspection program or its contractors or licensees.
At state inspection time, remember to tell your inspection or service
station in advance not to place your Subaru AWD vehicle on a two-
wheel dynamometer. Otherwise, serious transmission damage willresult.
Some states have started using dynamometers in their state inspection
programs in order to meet their obligation under federal law to implement
stricter vehicle emission standards to reduce air pollution from cars. A
dynamometer is a treadmill or roller-like testing device that allows your
car’ s wheels to turn while the car remains in one place. Depending on
the severity of a state ’s air pollution problems, the states must adopt
either a “basic” or “enhanced” vehicle emission inspection test. Nor-
mally, a portion of the basic emission test consists of an emission
inspector inserting an analyzer probe into the exhaust pipe of an idling
vehicle for a short period of time. States with more severe air pollution
problems are required to adopt an enhanced vehicle emission test. This
test simulates actual driving conditions on a dynamometer and permits

7-8
more accurate measurement of tailpipe emitted pollution than the basic emission test.
The U.S. Environmental Protection Agency (EPA) and states using two-
wheel dynamometers in their emission testing programs haveEXEMPTED Subaru AWD vehicles from the portion of the testing pro-
gram that involves a two-wheel dynamometer.
There are some states that use four-wheel dynamometers in their testing
programs. When properly used, that equipment will not damage an AWD Subaru vehicle.
Under no circumstances should the rear wheels be jacked off the
ground, nor should the driveshaft be disconnected for state emission testing.
Preparing to drive
You should perform the following checks and adjustments every day be-
fore you start driving.
1. Check that all windows, mirrors, and lights are clean and unob- structed.
2. Check the appearance and condition of the tires. Also check tires for
proper inflation.
3. Look under the vehicle for any sign of leaks.
4. Check that the hood, trunk and rear gate are fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside and outside mirrors.
7. Fasten your seatbelt. Check that your passengers have fastened theirseatbelts.
8. Check the operation of the warning and indicator lights when the igni-
tion switch is turned to the “ON” position.
9. Check the gauges, indicator and warning lights after starting the en-gine. NOTE Engine oil, engine coolant, brake fluid, washer fluid and other fluid
levels should be checked daily, weekly or at fuel stops.

CAUTION
Do not operate the starter motor continuously for more than ten
seconds. If the engine fails to start after operating the starter forfive to ten seconds, wait for ten seconds or more before tryingagain.
Starting the engine for a manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Press the clutch pedal to the floor and shift the shift lever into neutral.
Hold the clutch pedal to the floor while starting the engine. The starter
motor will only operate when the clutch pedal is pressed fully to the floor.
4. Turn the ignition switch to the “ON” position and check the operation
of the warning and indicator lights. Refer to the “Warning and indicator
light” section (chapter 3).
5. Turn the ignition switch to the “START” position without depressing
the accelerator pedal. Release the key immediately after the engine has
started.
If the engine does not start within ten seconds, wait a while and then turn the ignition switch to the “START” position again while depressing the ac-
celerator pedal half way down.
6. Confirm that all warning and indicator lights have gone off after the
engine has started. The fuel injection system automatically lowers the
idle speed as the engine warms up.
