Driving tips
"
Keep your engine tuned-up. If you feel the engine
running rough (misfiring, backfiring or incomplete
combustion), have your vehicle checked and repaired
by an authorized SUBARU dealer. " Do not apply undercoating or rust prevention treat-
ment to the heat shield of catalytic converter and the exhaust system.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.

"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." 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 engine stops. This
could create a fire hazard. " After 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." 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. " 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). " Never equip your vehicle with tires larger than those
specified in this manual. " Wash the vehicle’s underbody after off-road driving.
Suspension components are particularly prone to dirt
buildup, so they need to be washed thoroughly." 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.

Trailer towing
Your vehicle is designed and intended to be used pri-
marily as a passenger-carrying vehicle. Towing a trail-
er puts additional loads on your vehicle’s engine, driv-
etrain, brakes, tires and suspension and has an ad-
verse effect on fuel economy.
If you do decide to tow a trailer, your safety and satis-
faction depend upon proper use of correct equipment
and cautious operation of your vehicle. Seek the ad-
vice of your SUBARU dealer to assist you in purchas-
ing a hitch and other necessary towing equipment ap-
propriate for your vehicle. In addition, be sure to follow
the instructions on correct installation and use provid-
ed by the trailer and other towing equipment manufac-
turers.
SUBARU assumes no responsibility for injuries or ve-
hicle damage that result from trailer towing equipment,
or from any errors or omissions in the instructions ac-
companying such equipment or for your failure to fol-
low the proper instructions. !Warranties and maintenance
SUBARU warranties do not apply to vehicle damage
or malfunction caused by trailer towing. If you use your
vehicle to tow a trailer, more frequent maintenance will
be required due to the additional load. (Refer to “Main- tenance schedule under severe driving conditions” in
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.
"Adequate size trailer brakes are required
when the trailer and its cargo exceed 1,000 lbs
(453 kg) total weight. " Before towing a trailer, check the trailer total
weight, GVW, GAWs and tongue load. Make
sure the load and its distribution in your vehicle

Maintenance and serviceMaintenance schedule
The scheduled maintenance items required to be ser-
viced at regular intervals are shown in the “Warranty
and Maintenance Booklet”.
For details of your maintenance schedule, read the
separate “Warranty and Maintenance Booklet”.Maintenance precautions
When maintenance and service are required, it is rec-
ommended that all work be done by an authorized
SUBARU dealer.
If you perform maintenance and service by yourself,
you should familiarize yourself with the information
provided in this section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could cause improper
or unsafe vehicle operation. Any problems caused by
improper maintenance and service performed by you
are not eligible for warranty coverage.
"Testing of an All-Wheel Drive vehicle must
NEVER be performed on a single two-wheel dy-
namometer or similar apparatus. Attempting to
do so will result in transmission damage and in
uncontrolled vehicle movement and may cause
an accident or injuries to persons nearby." Always select a safe area when performing
maintenance on your vehicle." Always be very careful to avoid injury when
working on the vehicle. Remember that some of

3.0-liter models
A) Upper level
B) Lower level
4. Pull out the dipstick again and check the oil level on
it. If it is below the lower level, add oil to bring the level
up to the upper level.
" Use only engine oil with the recommended
grade and viscosity. " Be careful not to spill engine oil when adding
it. If oil touches the exhaust pipe, it may cause
a bad smell, smoke, and/or a fire.
If you check the oil level just after stopping the engine,
wait a few minutes for the oil to drain back into the oil
pan before checking the level.
To prevent overfilling the engine oil, do not add any
additional oil above the upper level when the engine is cold.
In 2.5-liter-engine models, the dipstick has a notch
above the upper level.
Just after driving or while the engine is warm, the en-
gine oil level reading may be in a range between the
upper level and the notch mark. This is caused by ther-
mal expansion of the engine oil. ! Changing the oil and oil filter
Change the oil and oil filter according to the mainte-
nance schedule in the “Warranty and Maintenance
Booklet”.
The engine oil and oil filter must be changed more fre-
quently than listed in the maintenance schedule when
driving on dusty roads, when short trips are frequently
made, or when driving in extremely cold whether.
1. Warm up the engine by letting the engine idle for
about 10 minutes to ease draining the engine oil.

A) Rubber gaskets
3. After refilling the reserve tank and the radiator, re-
install the caps and check that the rubber gaskets in-
side the radiator cap are in the proper position.
" Be careful not to spill engine coolant when
adding it. If coolant touches the exhaust pipe, it
may cause a bad smell, smoke, and/or a fire. " Do not splash the engine coolant over paint-
ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
! Changing the coolant
Always add genuine Subaru cooling system condition-
er whenever the coolant is replaced.
Change the engine coolant and add genuine Subaru
cooling system conditioner using the following proce-
dures according to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
1. Remove the under cover.
A) Drain plug
2. Place a proper container under the drain plug and
