Preparing to drive
You should p erform the following c hec ks and ad justm
ents every d ay b e-
fore you start d riving .
1. Chec k that all wind ows, mirrors, and lig hts are c lean and unob -
struc ted .
2. Chec k the ap p earanc e and c ond ition of the tires. Also c hec k tires for
p rop er inflation.
3. Look und er the vehic le for any sig n of leaks.
4. Chec k that the hood , trunk and rear g ate are full y c losed .
5. Chec k the ad justment of the seat.
6. Chec k the ad justment of the insid e and outsid e mi rrors.
7. Fasten your seatb elt. Chec k that your p asseng ers have fastened their
seatb elts.
8. Chec k the op eration of the warning and ind ic ator lig hts when the ig ni-
tion switc h is turned to the “ON ” p osition.
9. Chec k the g aug es, ind ic ator and warning lig hts af ter starting the en-
g ine. NOTE Engine oil, engine coolant, brake fluid, washer fluid and other fluid
levels should be checked daily, weekly or at fuel stops.
Starting the engine
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. Ap p ly the p arking b rake.
2. Turn off unnec essary lig hts and ac c essories.

ind ic ator lig ht will flash on and off when this sys
tem ac tivates.
NOTE Slight twitching of the brake pedal may be felt when the VDC-sys-
tem operates; a small degree of vehicle or steering wheel shaking may also be noticed in this situation. These are normal effects of
VDC operation and are no cause for alarm. When driving off immediately after starting the engine, a short-
lived operation noise may be noticed coming from the enginecompartment. This noise is generated as a result of a check beingperformed on the VDC system and is normal. Depending on the timing of activation of the brakes, certain situa-
tions may occur just after driving off where the brake pedal seemsto exhibit a jolting motion. This too is a consequence of the VDCoperational check and is normal. Activation of the VDC system will cause operation of the steering
wheel to feel slightly different compared to that for normal condi-tions. Even if the vehicle is equipped with a VDC system, it is important
that winter tires be used when driving on snow-covered or icyroads. (All four wheels should be fitted with tires of the same sizeand brand). Furthermore, if snow chains are to be used, they shouldbe fitted on the front wheels. When a vehicle is fitted with snow
chains, however, the effectiveness of the VDC system is reduced
and this should be taken into account when driving the vehicle insuch a condition. It is always important to reduce speed when approaching a cor-
ner, even if the vehicle is equipped with VDC. All four wheels should be fitted with tires of the same size, type,
and brand; furthermore, the amount of wear should be the same for
all four tires. If these precautions are not observed and non-match-ing tires are used, it is quite possible that the VDC system will beunable to operate correctly as intended. Always turn off the engine before replacing a tire as failure to do
so may render the VDC system unable to operate correctly.

VDC system monitor
HB4010FB
nVDC OFF indicator light
The VDC OFF ind ic ator lig ht turns on initially when the ig nition key
is turned to the ON p osition; it sub seq uently turns off 6 sec ond s after
the eng ine is started . This lig ht turns on to ind ic ate that the VDC and TC S systems are in
non-op eration (read y) mod e. This d oes not c onstitut e failure of the
VDC system. NOTE When the engine is started on cold mornings and in other sim-
ilar circumstances, a certain amount of time may pass before the
VDC OFF indicator light turns off. This occurs because the
engine has not yet warmed up and is completely normal. The
light will turn off when the engine has reached a suitable operat-ing temperature. When an engine problem occurs and the CHECK ENGINE
warning light turns on, the VDC OFF indicator light will also turnon. Depending on the type of gasoline used, it may take sometime
before the light goes out after the engine has been started.
The following two situations c ould ind ic ate malfunc tion of the VDC
system; if either should oc c ur, have an authorized SUBARU d ealer
c arry out an insp ec tion of that system at the first availab le op p ortunity.

If at any time you suspect that exhaust fumes are entering the
vehicle, have the problem checked and corrected as soon as pos-
sible. If you must drive under these conditions, drive only with allwindows fully open. Keep the trunk lid or rear gate closed while driving to prevent
exhaust gas from entering the vehicle.
NOTE Due to the expansion and contraction of the metals used in the
manufacture of the exhaust system, you may hear a crackling soundcoming from the exhaust system for a short time after the enginehas been shut off. This sound is normal.
Catalytic converter
WARNING
Avoid fire hazards. Do not drive or park the vehicle anywhere
near flammable materials (e.g. grass, paper, rags or leaves), be-
cause the catalytic converter operates at very high temperatures. Keep everyone and flammable materials away from the ex-
haust pipe while the engine is running. The exhaust gas is veryhot.

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.

Engine oil
Checking the oil level
Chec k the eng ine oil level at eac h fuel stop .
HSB008BB
HBB004BA
1. Park the vehic le on a level surfac e and stop the eng ine.
2. Pull out the d ip stic k, wip e it c lean, and insert it ag ain.
3. Be sure the d ip stic k is c orrec tly inserted until it stop s with the
g rap hic symb ol
on its top ap p earing as shown in the illustra-
tion.
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.
To p revent overfilling the eng ine oil, d o not ad d a ny ad d itional oil
ab ove the up p er level when the eng ine is c old .

1. Chec k the c oolant level on the outsid e of the res ervoir while the
eng ine is c ool.
2. If the level is c lose to or lower than the “LOW ” level mark, ad d
c oolant up to the “FULL ” level mark. If the reserve tank is emp ty, re-
move the rad iator c ap and refill as req uired .
