Maintenance and service

Maintenance and service
11-4
Always be very careful to avoid injury when
working on the vehicle. Remember that some of the materials in the vehicle may be hazard-
ous if improperly used or handled, for exam-ple, battery acid. Your vehicle should only be serviced by per-
sons fully competent to do so. Serious per-sonal injury may result to persons not experi-enced in servicing vehicles. Always use the proper tools and make cer-
tain that they are well maintained. Never get under the vehicle supported only
by a jack. Always use a safety stands to sup-port 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 per-
formed only by your SUBARU dealer. Ensure your eyes are free of oil and fluid, as
they can be harmful to your eyes. If you get one in your eyes, wash your eyes with clean
water. For your safety, you are wise to weareye protection.
Do not tamper with the wiring of the SRS
airbag system or seatbelt pretensioner sys-tem, or attempt to take its connectors apart,as that may activate the system or it can ren-der it inoperative. The wiring and connectorsof these systems are yellow for easy identifi- cation. NEVER use a circuit tester for these wiring. If your SRS airbag or seatbelt pretensionerneeds service, consult your nearest SUBARU
dealer. Before checking or servicing in the
engine compartment
Always stop the engine and set the parking
brake firmly to prevent the vehicle from mov- ing. Always let the engine cool down. Engine
parts become very hot when the engine is run-
ning and remain hot for some time after theengine is stopped. Do not spill engine oil, engine coolant, brake
fluid or any other fluid on hot engine compo-nents. 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 operate
suddenly even when the engine is stopped. When you do checking or servicing in the engine compartment whilethe engine is running
A running engine can be dangerous. Keep your fingers, hands, clothing, hair and toolsaway from the cooling fan, belts and any other
moving engine parts. Removing rings, watches and ties is advisable. Engine hood
To open the hood:

Drive belts
The alternator, power steering pump, and air condi-
tioner compressor depend on drive belts. Satisfacto-
ry performance requires that belt tension be correct.

To check belt tension, place a straightedge (ruler)
across two adjacent pulleys and apply a force of 22lb (98 N, 10 kg) midway between the pulleys by us- ing a spring scale. Belt deflection should be the
amount specified. If a belt is loose, cracked, or
worn, contact your SUBARU dealer.

check the wheel nuts again and retighten any nut that has become loose. Tire replacement
The wheels and tires are important and integral
parts of your vehicle ’s design; they cannot be
changed arbitrarily. The tires fitted as standard
equipment are optimally matched to the characteris-
tics of the vehicle and were selected to give the best
possible combination of running performance, ride
comfort, and service life. It is essential for every tireto have a size and construction matching those
shown on the tire placard and to have a speed sym-
bol and load index matching those shown on the tire
placard.
Using tires of a non-specified size detracts from
controllability, ride comfort, braking performance,
speedometer accuracy and odometer accuracy. It
also creates incorrect body-to-tire clearances and
inappropriately changes the vehicle ’s ground clear-
ance.
All four tires must be the same in terms of manufac-
turer, brand (tread pattern), construction, and size.
You are advised to replace the tires with new ones
that are identical to those fitted as standard equip- ment. For safe vehicle operation, SUBARU recommends
replacing all four tires at the same time. NOTE Unidirectional tires: Some tires have a specified direction of rotation. A tire of this type has an ar-
row or other mark on its side wall to indicate the direction of rotation. Install it in a manner the direction of rotation is correct when the vehicleis driven forward.
WARNING

All four tires must be the same in terms of
manufacturer, brand (tread pattern), construc-
tion, degree of wear, speed symbol, load indexand size. Mixing tires of different types, sizesor degrees of wear can result in damage to ve-
hicle’ s power train. Use of different types or
sized of tires can also dangerously reduce
controllability and braking performance andcan lead to an accident. Use only radial tires. Do not use radial tires
together with belted bias tires and/or bias-ply tires. Doing so can dangerously reduce con-
trollability, resulting in an accident.
