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.

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.

When you do checking or servicing in the engine
compartment while the engine is running
A running engine can be dangerous. Keep your fingers, hands, clothing, hair and tools away from the cooling fan, belts and anyother moving engine parts. Removing rings, watches and ties isadvisable.
Engine hood
WARNING
Always check that the hood is properly locked before you start
driving. If it is not, it might fly open while the vehicle is moving
and block your view, which may cause an accident and serious
bodily injury.

Checking the oil level
Check the engine oil level at each fuel stop.
HBB061BD
HBB004JA
1. Park the vehicle on a level surface and stop the engine.
2. Pull out the dipstick, wipe it clean, and insert it again.
3. Be sure the dipstick is correctly inserted until it stops with the
graphic symbol
on its top appearing as shown in the illustra-
tion.
4. Pull out the dipstick again and check the oil level on it. If it is belowthe lower level, add oil to bring the level up to the upper level.
CAUTION
Use only engine oil with the recommended grade and viscosity.
If you check the oil level just after stopping the engine, wait a few min-
utes for the oil to drain back into the oil pan before checking the level.
To prevent overfilling the engine oil, do not add any additional oilabove the upper level when the engine is cold.
In 2.5-liter-engine models, the dipstick has a notch above the upper level.
Just after driving or while the engine is warm, the engine oil level
reading may be in a range between the upper level and the notch
mark. This is caused by thermal expansion of the engine oil.
