cause of the CHECK ENGINE warning light/malfunction indicatorlamp coming on could be a loose or missing fuel filler cap.Remove the cap and retighten it until it clicks. Make sure nothing
is interfering with the sealing of the cap. Tightening the cap will
not make the CHECK ENGINE warning light turn off immediately.It may take several driving trips. If the light does not go out, take
your vehicle to your authorized SUBARU dealer immediately.

CAUTION
Do not operate the washer continuously for more than ten se-
conds, or when the washer fluid tank is empty. This may cause
overheating of the washer motor. Check the washer fluid level fre-
quently, such as at fuel stops. Do not operate the wipers when the windshield or rear window
is dry. This may scratch the glass, damage the wiper blades and
cause the wiper motor to burn out. Before operating the wiper on
a dry windshield or rear window, always use the windshield
washer. In freezing weather, be sure that the wiper blades are not fro-
zen to the windshield or rear window before switching on thewipers. Attempting to operate the wiper with the blades frozen tothe window glass could cause not only the wiper blades to be
damaged but also the wiper motor to burn out. If the wiper bladeis frozen to the window glass, be sure to operate the defroster or
rear window defogger before turning on the wiper. If the wipers stop during operation because of ice or some oth-
er obstruction on the window, the wiper motor could burn outeven if the wiper switch is turned off. If this occurs, promptly stopthe vehicle in a safe place, turn the ignition switch to the “LOCK”
position and clean the window glass to allow proper wiper opera-tion. Use clean water if windshield washer fluid is unavailable. In
areas where water freezes in winter, use SUBARU Windshield
Washer Fluid or the equivalent. (See “Windshield washer fluid ”
section in chapter 10.)Also, when driving the vehicle when there are freezing tempera-tures, use non-freezing type wiper blades. Do not clean the wiper blades with gasoline or a solvent, such
as paint thinner or benzene. This will cause deterioration of thewiper blades.

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.

levels should be checked daily, weekly or at fuel stops.
Driving in foreign countries
When p lanning to use your vehic le in another c ountr y:
Confirm the availab ility of the c orrec t fuel. (Refe r to the “Fuel req uire-
ment ” sec tion in this c hap ter.)

When you feel the ABS system operating, you should maintain
constant brake pedal pressure. Do not pump the brake pedal
since doing so may defeat the operation of the ABS system.
The ABS system p revents the loc k-up of wheels whic h may oc c ur d uring
sud d en b raking or b raking on slip p ery road surfac es . This help s p revent
the loss of steering c ontrol and d irec tional stab il ity c aused b y wheel
loc k-up .
When the ABS system is op erating , you may hear a c h attering noise or
feel a slig ht vib ration in the b rake p ed al. This is normal when the ABS
op erates.
The ABS system will not op erate when the vehic le sp eed is b elow
ap p roximately 6 mp h (10 km/h).
ABS system self-checking
You may feel a slig ht shoc k in the b rake p ed al and hear the op erating
sound of ABS from the eng ine c omp artment just after the vehic le is
started . This is c aused b y an automatic func tional test of the ABS sys-
tem b eing c arried out and d oes not ind ic ate any ab n ormal c ond ition.

Always use the proper tools and make certain that they are
well maintained. Never get under the vehicle supported only by 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. Wear adequate eye protection to guard against getting oil or
other fluids in your eyes. If something does get in your eyes,
thoroughly wash it out with clean water. Because the fuel system is under pressure, replacement of the
fuel filter should be performed only by your SUBARU dealer. The SRS airbag has no user-serviceable parts. Tampering with
or disconnecting the system ’s wiring could result in accidental
inflation of the airbag or could make the system inoperative,
which may result in serious injury. The wiring harnesses of theSRS airbag system are covered with yellow insulation and the
connectors of the system are yellow, for easy identification. Donot use electrical test equipment on any circuit related to the SRSairbag system. For required servicing of the SRS airbag, see 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.
