running rough (misfiring, backfiring or incomplete
combustion), have your vehicle checked and repaired
by an authorized SUBARU dealer. yDo not apply undercoating or rust prevention treat-
ment to the heat shield of catalytic converter and the
exhaust system.
y Avoid fire hazards. Do not drive or park the
vehicle anywhere near flammable materials
(e.g. grass, paper, rags or leaves), because the
catalytic converter operates at very high tem-
peratures. y Keep everyone and flammable materials
away from the exhaust pipe while the engine is
running. The exhaust gas is very hot.
Periodic inspections
To keep your vehicle in the best condition at all times,
always have the recommended maintenance services
listed in the maintenance schedule in the “Warranty
and Maintenance Booklet” performed at the specified
time or mileage intervals.

Driving tips
Off road driving
Because of the AWD feature and higher ground clear-
ance, your SUBARU can be driven on ordinary roads
or off-road. But please keep in mind that an AWD
SUBARU is a passenger car and is neither a conven-
tional off-road vehicle nor an all-terrain vehicle. If you
do take your SUBARU off-road, certain common
sense precautions such as the following should be taken: y
Make certain that you and all of your passengers
are wearing seatbelts. y Carry some emergency equipment, such as a tow-
ing rope or chain, a shovel, wheel blocks, first aid kit
and cell phone or citizens band radio. y Drive carefully. Do not take unnecessary risks by
driving in dangerous areas or over rough terrain.y 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. y Do not drive across steep slopes. Instead, drive ei-
ther straight up or straight down the slopes. A vehicle
can much more easily tip over sideways than it can
end over end. Avoid driving straight up or down slopes
that are too steep.y Avoid sharp turning maneuvers, especially at higher speeds. y
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 fingers and
thumbs on the outside of the rim.y 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 firmness and ensure
that the bed of the stream is flat. Drive slowly and com-
pletely through the stream. The water should be shal-
low enough that it does not reach the vehicle’s under-
carriage. 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; regard-
less of its depth, it can wash away the ground from un-
der your tires, resulting in possible loss of traction and
even vehicle rollover. y Always check your brakes for effectiveness immedi-
ately after driving in sand, mud or water. Do this by
driving slowly and stepping on the brake pedal. Re-
peat that process several times to dry out the brake
discs and brake pads.y Do not drive or park over or near flammable materi-
als 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 the engine stops. This

could create a fire hazard. yAfter driving through tall grass, mud, rocks, 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.y Secure all cargo carried inside the vehicle and make
certain that it is not piled higher than the seatbacks.
During sudden stops or jolts, unsecured 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. y 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 between “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). y Never equip your vehicle with tires larger than those
specified in this manual. y Frequent driving of an AWD vehicle under hard-driv- ing conditions such as rough roads or off roads will ne-
cessitate more frequent replacement of engine oil,
brake fluid and transmission oil than that specified in
the maintenance 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 pre-
cautions such as those listed above is not eligible forwarranty coverage. y
Wash the vehicle’s underbody after off-road driving.
Suspension components are particularly prone to dirt
buildup, so they need to be washed thoroughly.
y Always maintain a safe driving speed accord-
ing to the road and weather conditions in order
to avoid having an accident on a sharp turn,
during sudden braking or under other similar
conditions.y Always use the utmost care in driving – over-
confidence because you are driving an All-
Wheel Drive vehicle could easily lead to a seri-
ous accident.

Driving tips
Winter driving „
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 re-
duce battery capacity. The battery must be in good
condition to provide enough power for cold winterstarts.
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 or glycerin.
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 anti-
freeze solution. Do not use engine antifreeze or other
substitutes because they may damage the paint of the vehicle. T
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 accelerator 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 periodically.

TParking in cold weather
Do not use the parking brake when parking for long
periods in cold weather since it could freeze in that po-
sition. Instead, observe the following:
1. Place the shift lever in “1” or “R” for manual trans-
mission vehicles, and in “P” for automatic transmissionvehicles.
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 covered with snow, or has been left
parked during a snowstorm, icing may 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.
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.
T Refueling in cold weather
To help prevent moisture from forming in the fuel sys-
tem and the risk of its freezing, use of an antifreeze ad-
ditive in the fuel tank is recommended during cold
weather.
Use only additives that are specifically designed for
this purpose. When an antifreeze additive is used, its
effect lasts longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used for an extend-
ed period, it is best to have the fuel tank filled to capac- ity. „ Driving on snowy and icy roads
To prevent skidding and slipping, avoid sudden brak-
ing, abrupt acceleration, high-speed driving, and
sharp turning when driving on snowy or icy roads.
Always maintain ample distance between your vehicle
and the vehicle ahead of you to avoid the need for sud-
den braking.
To supplement the foot brake, use the engine brake
effectively to control the vehicle speed. (Shift into a

the “Warranty and Maintenance Booklet”.)
Under no circumstances should a trailer be towed with
a new vehicle or a vehicle with any new powertrain
component (engine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles (1,600 km) of
driving. „
Maximum load limits
Never exceed the maximum load limits ex-
plained below. Exceeding the maximum load
limits could cause personal injury and/or vehi-
cle damage.
yAdequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. y Before towing a trailer, check the trailer total
weight, GVW, GAWs and tongue load. Make
sure the load and its distribution in your vehicle
and trailer are acceptable.
T Total trailer weight
Total trailer weight
The total trailer weight (trailer weight plus its cargo
load) must never exceed the maximum weight shown
below.

In case of emergency
Engine overheating
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 cool-
ant is under pressure. Removing the cap while
the engine is still hot could release a spray of
boiling hot coolant, which could burn you very
seriously.
If the engine overheats, safely pull off the road and
stop the vehicle in a safe place. „ If steam is coming from the engine
compartment
Turn the engine off and get everyone away from the
vehicle until it cools 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 compart- ment. Confirm that the cooling fan is turning. If the fan is not
turning, immediately turn the engine off and contact
your authorized dealer for repair.
3. After the engine coolant temperature has dropped,
turn off the engine.
If the temperature gauge stays at the overheated
zone, turn the engine off.
4. After the engine has fully cooled down, check the
coolant level in the reserve tank.
If the coolant level is below the “LOW” mark, add cool-
ant up to the “FULL” mark.
5. If there is no coolant in the reserve tank, add cool-
ant 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 the ra-
diator. After the pressure has been fully released, re-
move the cap by pressing down and turning it.
