Catalytic converterWARNING
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.
HB3003BA
The catalytic converter is installed in the exhaust system. It serves as
catalyst to reduce HC, CO and NOx in exhaust gases, thus providing
cleaner exhaust.
To avoid damage to the catalytic converter: Use only unleaded gasoline. Even a small amount of leaded gasoline
will damage the catalytic converter. Never start the engine by pushing or pulling the vehicle.
Avoid racing the engine.
Never turn off the ignition switch while the vehicle is moving.
Keep your engine tuned-up. If you feel the engine running rough (mis-
firing, backfiring or incomplete combustion), have your vehicle checked
and repaired by an authorized SUBARU dealer. Do not apply undercoating or rust prevention treatment to the heat
shield of catalytic converter and the exhaust system.

Make certain that you and all of your passengers are wearing seat
belts. Carry some emergency equipment, such as a towing rope or chain, a
shovel, wheel blocks, first aid kit and portable phone or citizens bandradio. Drive carefully. Do not take unnecessary risks by driving in dangerous
areas or over rough terrain. Slow down and employ extra caution at all times. When driving off-
road, you will not have the benefit of marked traffic lanes, banked
curves, traffic signs and the like. Do not drive across steep slopes. Instead, drive either straight up or
straight down the slopes. A vehicle can much more easily tip over side-
ways than it can end over end. Avoid driving straight up or down slopes
that are too steep. Avoid sharp turning maneuvers, especially at higher speeds.
Do not grip the inside or spokes of the steering wheel. A bad bump
could jerk the wheel and injure your hands. Instead drive with your fin-gers and thumbs on the outside of the rim. If driving through water, such as when crossing shallow streams, first
check the depth of the water and the bottom of the stream bed for firm-
ness and ensure that the bed of the stream is flat. Drive slowly and com-
pletely through the stream. The water should be shallow enough that it
does not reach the vehicle ’s undercarriage. Water entering the engine air
intake or the exhaust pipe or water splashing onto electrical parts may
damage your vehicle and may cause it to stall. Never attempt to drive
through rushing water; regardless of its depth, it can wash away the
ground from under your tires, resulting in possible loss of traction and
even vehicle rollover. Always check your brakes for effectiveness immediately after driving
in sand, mud or water. Do this by driving slowly and stepping on the
brake pedal. Repeat that process several times to dry out the brakediscs and brake pads. Do not drive or park over or near flammable materials such as dry
grass or fallen leaves, as they may burn easily. The exhaust system is
very hot while the engine is running and right after engine stops. This
could create a fire hazard.

After driving through tall grass, mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper, rags, stones, sand, etc. adhering to
or trapped on the underbody. Clear off any such matter from the under-
body. If the vehicle is used with these materials trapped or adhering to
the underbody, a mechanical breakdown or fire could occur. Secure all cargo carried inside the vehicle and make certain that it is
not piled higher than the seatbacks. During sudden stops or jolts, unse-
cured cargo could be thrown around in the vehicle and cause injury. Do not pile heavy loads on the roof. Those loads raise the vehicle ’s
center of gravity and make it more prone to tip over. Cargo should be evenly distributed over the cargo bed. Keep heavier
items as low and far forward as possible. Loading the vehicle improperly
can deteriorate handling capability and contribute to loss of vehicle con-
trol. Be sure the cargo is secured properly. Unsecured cargo in the cargo
bed can be thrown around when driving on off-road. To prevent loose
cargo from entering the passenger compartment, always close the
switchback door while driving off-road. Always close the tailgate while driving off-road. Also remove the bed
extender (if so equipped) to avoid damage. If you must rock the vehicle to free it from sand or mud, depress the
accelerator pedal slightly and move the selector lever back and forth be-tween “D” and “R” repeatedly. Do not race the engine. For the best pos-
sible traction, avoid spinning the wheels when trying to free the vehicle. When the road surface is extremely slippery, you can obtain better
traction by starting the vehicle with the transmission in 2nd than 1st (both
for MT and AT). Never equip your vehicle with tires larger than those specified in this
manual. Frequent driving of an AWD vehicle under hard-driving conditions such
as rough roads or off roads will necessitate more frequent replacement of
engine oil, brake fluid and transmission oil than that specified in the main-
tenance schedule described in the “Warranty and Maintenance Booklet ”.
Remember that damage done to your Subaru while operating it off-road
and not using common sense precautions such as those listed above is

Winter driving
HB8046AA
Operation during cold weather
Carry some emergency equipment, such as tire chains, a window
scraper, a bag of sand, flares, a small shovel, and jumper cables.
Check the battery and cables. Cold temperatures reduce battery ca-
pacity. The battery must be in good condition to provide enough pow-
er for cold winter starts.
Use an engine oil of proper grade and viscosity for cold weather.
Heavy summer oil will cause harder starting.
Keep the door locks from freezing by squirting them with deicer orglycerin.
Forcing a frozen door open may damage or separate the rubber
weather strips around the door. If the door is frozen, use hot water to
melt the ice, and afterwards thoroughly wipe the water away.
Use a windshield washer fluid that contains an antifreeze solution. Do
not use engine antifreeze or other substitutes because they may dam-age the paint of the vehicle. n Before driving your vehicle
Before entering the vehicle, remove any snow or ice from your shoes

because that could make the pedals slippery and dangerous.
While warming up the vehicle before driving, check that the accelera-
tor pedal, brake pedal, and all other controls operate smoothly.
Clear away ice and snow that has accumulated under the fenders to
avoid making steering difficult. During severe winter driving, stop
when and where it is safe to do so and check under the fenders peri-
odically. nParking in cold weather
WARNING
Snow can trap dangerous exhaust gases under your vehicle. Keep snow clear of the exhaust pipe and from around your
vehicle if you park the vehicle in snow with the engine running.
Do not use the parking brake when parking for long periods in cold
weather since it could freeze in that position. Instead, observe the fol-lowing:
1. Place the shift lever in “1” or “R” for manual transmission vehicles,
and in “P” for automatic transmission vehicles.
2. Use tire stops under the tires to prevent the vehicle from moving.
When the vehicle is parked in snow or when it snows, raise the wiper
blades off the glass to prevent damage to them.
When the vehicle has been left parked after use on roads heavily cov-
ered with snow, or has been left parked during a snowstorm, icingmay develop on the brake system, which could cause poor braking
action. Check for snow or ice buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it, being careful not to damage
the disc brakes and brake hoses and ABS harness. n Refueling in cold weather
To help prevent moisture from forming in the fuel system and the risk
of its freezing, use of an antifreeze additive in the fuel tank is recom-
mended during cold weather.

nBefore starting out on a trip
Check that the vehicle and vehicle-to-hitch mounting are in good
condition. If any problems are apparent, do not tow the trailer. Check that the vehicle sits horizontally with the trailer attached. If
the vehicle is tipped sharply up at the front and down at the rear,
check the total trailer weight, GVW, GAWs and tongue load again,
then confirm that the load and its distribution are acceptable. Check that the tire pressures are correct.
Check that the vehicle and trailer are connected properly. Confirm
that. – the trailer tongue is connected properly to the hitch ball.
– the trailer lights connector is connected properly and trailer ’s
brake lights illuminate when the vehicle ’s brake pedal is pressed,
and that the trailer ’s turn signal lights flash when the vehicle ’s turn
signal lever is operated.– the safety chains are connected properly.
– all cargo in the trailer is secured safety in position.
– the side mirrors provide a good rearward field of view without a
significant blind spot.
Sufficient time should be taken to learn the “feel” of the vehicle/
trailer combination before starting out on a trip. In an area free of traf-
fic, practice turning, stopping and backing up. n Driving with a trailer
You should allow for considerably more stopping distance when
towing a trailer. Avoid sudden braking because it may result in skid-
ding or jackknifing and loss of control. Avoid abrupt starts and sudden accelerations. If your vehicle has a
manual transmission, always start out in first gear and release the
clutch at moderate engine revolution. Avoid uneven steering, sharp turns and rapid lane changes.
Slow down before turning. Make a longer than normal turning
radius because the trailer wheels will be closer than the vehicle
wheels to the inside of the turn. In a tight turn, the trailer could hit yourvehicle. Crosswinds will adversely affect the handling of your vehicle and

The temporary spare tire is smaller and lighter than a conventional tire
and is designed for emergency use only. Remove the temporary spare
tire and re-install the conventional tire as soon as possible because the
spare tire is designed only for temporary use.
Check the inflation pressure of the temporary spare tire periodically to
keep the tire ready for use. The correct pressure is 60 psi (420 kPa, 4.2
kg/cm 2
).
When using the temporary spare tire, note the following: Do not exceed 50 mph (80 km/h).
Do not put a tire chain on the temporary spare tire. Because of the
smaller tire size, a tire chain will not fit properly. Do not use two or more temporary spare tires at the same time.
Do not drive over obstacles. This tire has a smaller diameter, so
road clearance is reduced. When the wear indicator appears on the tread, replace the tire.

NOTE [Automatic transmission vehicle] Before driving your vehicle with the temporary spare tire, put a spare fuse inside the FWD connectorlocated in the engine compartment and confirm that the Front-wheeldrive warning light comes on. The all wheel drive capability of the
vehicle has now been deactivated. After re-installing the convention-al tire, remove the spare fuse from the FWD connector in order to
reactivate all wheel drive.

Engine overheating
WARNING
Never attempt to remove the radiator cap until the engine has been shut off and has fully cooled down. When the engine is hot,the coolant is under pressure. Removing the cap while the engineis still hot could release a spray of boiling hot coolant, which
could burn you very seriously.
If the engine overheats, pull off the road safely and stop the vehicle in asafe place. If steam is coming from the engine compartment
Turn the engine off and get everyone away from the vehicle until itcools down. If no steam is coming from the engine compartment
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compartment.
Confirm that the cooling fan is turning. If the fan is not turning, im-
mediately turn the engine off and contact your authorized dealer for
repair.
3. After the engine coolant temperature has dropped, turn off the en-gine.
If the temperature gauge stays at the overheated zone, turn the en-
gine off.
4. After the engine has fully cooled down, check the coolant level in
the reserve tank.If the coolant level is below the “MIN” mark, add coolant up to the
“MAX” mark.
5. If there is no coolant in the reserve tank, add coolant to the reserve
tank. Then remove the radiator cap and fill the radiator with coolant.
If you remove the radiator cap from a hot radiator, first wrap a thick
cloth around the radiator cap, then turn the cap counterclockwise
slowly without pressing down until it stops. Release the pressure from
