Towing with all wheels on the ground
WARNING
Never turn the ignition switch to the “LOCK” position while the
vehicle is being towed because the steering wheel and the direc- tion of the wheels will be locked. Remember that the brake booster and power steering do not
function when the engine is not running. Because the engine isturned off, it will take greater effort to operate the brake pedal andsteering wheel.
CAUTION
If transmission failure occurs, transport your vehicle on a flat-
bed truck. For vehicles with automatic transmission, the traveling speed
must be limited to less than 20 mph (30 km/h) and the traveling
distance to less than 31 miles (50 km). For greater speeds and
distances, transport your vehicle on a flat-bed truck.

1. Chec k the transmission and d ifferential oil level s and ad d oil to
b ring it to the up p er level if nec essary.
2. Release the p arking b rake and p ut the transmissio n in neutral.
3. The ig nition switc h should b e in the “ACC ” p osition while the ve-
hic le is b eing towed .

10-2Exterior care
Washing
CAUTION
When washing the vehicle, the brakes may get wet. As a result,
the brake stopping distance will be longer. To dry the brakes, drive the vehicle at a safe speed while lightly pressing the brakepedal to heat up the brakes. Do not wash the engine compartment and areas adjacent to it.
If water enters the engine air intake, electrical parts or the power
steering fluid reservoir, it will cause engine trouble or faulty
power steering respectively.
The b est way to p reserve your vehic le ’s b eauty is freq uent washing .
Wash the vehic le at least onc e a month to avoid c on tamination b y road
g rime.
Wash d irt off with a wet sp ong e and p lenty of lukew arm or c old water. Do
not wash the vehic le with hot water and in d irec t s unlig ht.
Salt, c hemic als, insec ts, tar, soot and b ird d rop p i ng s should b e washed
off b y using a lig ht d eterg ent, as req uired . If you use a lig ht d eterg ent,
make c ertain that it is a neutral d eterg ent. Do not use strong soap or
c hemic al d eterg ents. All c leaning ag ents should b e p romp tly flushed
from the surfac e and not allowed to d ry there. Rins e the vehic le thor-
oug hly with p lenty of lukewarm water. Wip e the rema ining water off with a
c hamois or soft c loth. NOTE When having your vehicle washed in an automatic car wash, make
sure beforehand that the car wash is of suitable type. If the vehicle
is equipped with a rear/roof spoiler, it may be damaged by car washbrushes or other equipment.

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 it 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.

4. Pull out the d ip stic k ag ain and c hec k the oil lev el on it. If it is b elow
the lower level, ad d oil to b ring the level up to t he up p er level.
CAUTION
Use only engine oil with the recommended grade and viscosity.
If you c hec k the oil level just after stop p ing the eng ine, wait a few min-
utes for the oil to d rain b ac k into the oil p an b ef ore c hec king the level.
Just after d riving or while the eng ine is warm, the eng ine oil level
read ing may b e in a rang e b etween the up p er level a nd the notc h
mark. This is c aused b y thermal exp ansion of the en g ine oil.

Changing the oil and oil filter
Chang e the oil and oil filter ac c ord ing to the main tenanc e sc hed ule in
the “Warranty and Maintenanc e Booklet ”.
The eng ine oil and oil filter must b e c hang ed more freq uently than
listed in the maintenanc e sc hed ule when d riving on d usty road s,
when short trip s are freq uently mad e, or when d rivi ng in extremely
c old whether.
1. Warm up the eng ine b y letting the eng ine id le for ab out 10 minutes
to ease d raining the eng ine oil.
2. Park the vehic le on a level surfac e and stop the eng ine.
3. Remove the oil filler c ap .

4. Drain out the eng ine oil b y removing the d rain p l ug while the en-
g ine is still warm. The used oil should b e d rained into an ap p rop riate
c ontainer and d isp osed of p rop erly.
WARNING
Be careful not to burn yourself with hot engine oil.
5. Wip e the seating surfac e of the d rain p lug with a c lean c loth and
tig hten it sec urely with a new sealing washer after the oil has c om-
p letely d rained out.

Recommended grade and viscosity CAUTION
Use only engine oil with the recommended grade and viscosity.
Oil grade: API classification SJ or SH with the words “ENERGY

Cooling system
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33F ( –36 C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,
even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehic le emp loys an elec tric c ooling fan whic h is thermostatic ally
c ontrolled to op erate when the eng ine c oolant reac h es a sp ec ific tem-
p erature.
If the rad iator c ooling fan d oes not op erate even w hen the eng ine
c oolant temp erature g aug e exc eed s the normal op erat ing rang e, the
c ooling fan c irc uit may b e d efec tive. Chec k the fus e and rep lac e it if
nec essary. If the fuse is not b lown, have the c ooli ng system c hec ked
b y your SUBARU d ealer.
If freq uent ad d ition of c oolant is nec essary, there may b e a leak in the
eng ine c ooling system. It is rec ommend ed that the c ooling system
and c onnec tions b e c hec ked for leaks, d amag e, or lo oseness.
