is caught under the cap, the CHECK ENGINE warning light may come on. Refer to the “Warning and indicator lights ” section lo-
cated in chapter 3.
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

than three. Under this condition, the vehicle operator should be
instructed to drive his/her vehicle for a few days to set the monitors and
return for an emission re-inspection.
Owners of rejected or failing vehicles should contact their Subaru
Dealer for service.
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.

The catalytic converter is installed in the exhaust system. It serves as
catalyst to reduce HC, CO and NOx in exhaust gases, thus providing
cleaner exhaust.
To avoid damage to the catalytic converter:
Use only unleaded gasoline. Even a small amount of leaded gasoline
will damage the catalytic converter. Never start the engine by pushing or pulling the vehicle.
Avoid racing the engine.
Never turn off the ignition switch while the vehicle is moving.
Keep your engine tuned-up. If you feel the engine running rough (mis-
firing, backfiring or incomplete combustion), have your vehicle checked
and repaired by an authorized SUBARU dealer. Do not apply undercoating or rust prevention treatment to the heat
shield of catalytic converter and the exhaust system.
Periodic inspections
To keep your vehicle in the best condition at all times, always have the
recommended maintenance services listed in the maintenance schedulein the “Warranty and Maintenance Booklet ” performed at the specified
time or mileage intervals.
Driving in foreign countries
When planning to use your vehicle in another country: Confirm the availability of the correct fuel. (Refer to the “Fuel require-
ment” section in chapter 7.)
Comply with all regulations and requirements of each country.

8-36Connection of trailer lights to your vehicle
’s electrical system requires
modifications to the vehicle ’s lighting circuit to increase its capacity
and accommodate wiring changes. To ensure the trailer lights are
connected properly, please consult your SUBARU dealer. Check for
proper operation of the turn signals, the brake lights and parkinglights each time you hitch up. n Tires
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load.
Use of the temporary spare tire when towing can result in failureof the spare tire and/or less stability of the vehicle.
Make sure that all the tires on your vehicle are properly inflated. OUTBACK: The recommended cold tire pressure under trailer
towing conditions is indicated on the tire placard located under thedoor striker on the driver ’s side. Adjust the rear tire pressure to the
recommended pressure shown on the tire placard when the tires
are cold. Normal pressure should be maintained in the front tires.Other models: It is recommended to inflate the rear tires to 3 psi
(20 kPa, 0.2 kg/cm 2
) above their normal operating pressure when
the tires are cold. Normal pressure should be maintained in the
front tires.
Trailer tire condition, size, load rating and proper inflation pressure
should be in accordance with the trailer manufacturer ’s specifications.
In the event your vehicle gets a flat tire when towing a trailer, ask a
commercial road service to repair the flat tire.
If you carry a regular size spare tire in your vehicle or trailer as a pre-
caution against getting a flat tire, be sure that the spare tire is firmly
secured.

12. Put on the spare tire. Replace the wheel nuts. Tighten them by hand.
13. Turn the jack handle counterclockwise to lower the vehicle.
14. Use the wheel nut wrench to securely tighten the wheel nuts to the
specified torque, following the tightening order in the illustration.
OM-H0377
The torque for tightening the nuts is 58 to 72 ft-lb (78 to 98 N-m, 8 to 10
kg-m). This torque is equivalent to applying about 88 to 110 lbs (40 to 50
kg) at the top of the wheel nut wrench. Never use your foot on the wheel
nut wrench or a pipe extension on the wrench because you may exceed
the specified torque. Have the wheel nut torque checked at the nearest
automotive service facility.
15. Store the flat tire in the spare tire compartment.

Towing
WARNING
Never tow AWD vehicles (both AT and MT) with the front wheelsraised off the ground while the rear wheels are on the ground, orwith the rear wheels raised off the ground while the front wheelsare on the ground. This will cause the vehicle to spin away due tothe operation or deterioration of the center differential.

If towing is necessary, it is best done by your SUBARU dealer or a com-
mercial towing service. Observe the following procedures for safety.
Towing and tie-down hooks
CAUTION
Use only specified towing hooks and tie-down hooks. Never
use suspension parts or other body parts for towing or tie-downpurposes. Never use the tie-down hook closest to the muffler under the
vehicle for towing purposes. Do not apply excessive lateral load to the towing hooks.

Maintenance schedule
The scheduled maintenance items required to be serviced at regular in-
tervals are shown in the
“Warranty and Maintenance Booklet ”.
For details of your maintenance schedule, read the separate “Warranty
and Maintenance Booklet ”.
Maintenance precautions
When maintenance and service are required, it is recommended that all
work be done by an authorized SUBARU dealer.
If you perform maintenance and service by yourself, you should familiar-
ize yourself with the information provided in this section on general main-
tenance and service for your SUBARU.
Incorrect or incomplete service could cause improper or unsafe vehicle
operation. Any problems caused by improper maintenance and service
performed by you are not eligible for warranty coverage. WARNING
Testing of an All-Wheel Drive vehicle must NEVER be per-
formed on a single two-wheel dynamometer or similar apparatus.Attempting to do so will result in transmission damage and inuncontrolled vehicle movement and may cause an accident or
injuries to persons nearby. Always select a safe area when performing maintenance on
your vehicle. Always be very careful to avoid injury when working on the ve-
hicle. Remember that some of the materials in the vehicle may behazardous if improperly used or handled, for example, batteryacid. Your vehicle should only be serviced by persons fully compe-
tent to do so. Serious personal injury may result to persons not
experienced in servicing vehicles.

11-4
Always use the proper tools and make certain that they are
well maintained. Never get under the vehicle supported only by a jack. Always
use a safety stands to support the vehicle. Never keep the engine running in a poorly ventilated area,
such as a garage or other closed areas. Do not smoke or allow open flames around the fuel or battery.
This will cause a fire. Because the fuel system is under pressure, replacement of the
fuel filter should be performed only by your SUBARU dealer. Wear adequate eye protection to guard against getting oil or
fluids in your eyes. If something does get in your eyes, thorough-
ly wash them out with clean water. Do not tamper with the wiring of the SRS airbag system or
seatbelt pretensioner system, or attempt to take its connectorsapart, as that may activate the system or it can render it inopera-tive. The wiring and connectors of these systems are yellow for
easy identification. NEVER use a circuit tester for these wiring. If your SRS airbag or seatbelt pretensioner needs service, con-
sult your nearest SUBARU dealer. Before checking or servicing in the engine compart- ment
Always stop the engine and set the parking brake firmly to pre-
vent the vehicle from moving. Always let the engine cool down. Engine parts become very
hot when the engine is running and remain hot for some time af-ter the engine is stopped. Do not spill engine oil, engine coolant, brake fluid or any other
fluid on hot engine components. This may cause a fire. Always remove the key from the ignition switch. When the
ignition switch is in the “ON” position, the cooling fan may oper-
ate suddenly even when the engine is stopped.
