Air filtration system Replace the filter element according to the
replacement schedule as follows. This
schedule should be followed to maintain
the filter ’ s dust collection ability. Under
extremely dusty conditions, the filter
should be replaced more frequently. It is
recommended that you have your filter
checked or replaced by your SUBARU
dealer. For replacement, use only a
genuine SUBARU air filter kit. For the
replacement schedule, refer to the “ War-
ranty and Maintenance Booklet ” .
CAUTIONContact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter:
. Reduction of the airflow through
the vents.
. Windshield gets easily fogged or
misted.
NOTE The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained. & Replacing an air filter 1. Remove the glove box.
NOTE We recommend that you take mea-
sures to protect the center console
with masking tape first, so that you
avoid scratching the center console
with the glove box.
(1) Open the glove box.
(2) Remove the damper shaft from the
glove box. 1) Stopper
(3) Push both sides of the glove box
inside to unlock the stoppers and then
pull down the glove box as far as it will
go.
(4) Pull out the glove box horizontally Climate control/Air filtration system

surfaces of the vehicle. Because
fuel may damage the paint, be
sure to wipe off any spilled fuel
quickly. Paint damage caused by
spilled fuel is not covered under
the SUBARU Limited Warranty.
. Always use a genuine SUBARU
fuel filler cap. If you use the
wrong cap, it may not fit or have
proper venting and your fuel tank
and emission control system
may be damaged. It could also
lead to fuel spillage and a fire.
. Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank
could cause damage to the en-
gine. Continuing to operate your
vehicle at an extremely low fuel
level may result in a reduction of
engine performance. State emission testing (U.S.
only) WARNINGTesting of an All-Wheel Drive model
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby.
CAUTION. At state inspection time, remem-
ber to tell your inspection or
service station in advance not to
place your SUBARU AWD vehicle
on a two-wheel dynamometer.
Otherwise, serious transmission
damage will result.
. Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of
the state inspection program or
its contractors or licensees.
California and a number of federal states have Inspection/Maintenance programs to
inspect your vehicle ’ s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle ’ s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine ’ s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed
to detect engine and transmission pro-
blems that might cause the vehicle emis-
sions to exceed allowable limits. OBDII
inspections apply to all 1996 model year
and newer passenger cars and trucks.
Over 30 states plus the District of Colum-
bia have implemented emission inspec-
tion of the OBDII system.
. The inspection of the OBDII system
consists of a visual operational check of
the “ CHECK ENGINE ” warning light/mal-
function indicator light (MIL) and an
examination of the OBDII system with an
electronic scan tool.
. A vehicle
passes the OBDII system
inspection if proper operation of the
“ CHECK ENGINE ” warning light is ob-
served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.Starting and operating/State emission testing (U.S. only)

Starting and operating/Remote engine start system (dealer option)
! Stopping the engine
Press and hold the lock button to stop the
engine with remote engine start system.
! Automatic engine shutdown
The remote engine start system will
automatically shut down or will not start
the engine under the following conditions.

violate state, provincial, or local laws and
regulations. Check the laws in your area to
determine which setting is permitted. & Entering the vehicle while it
is running via remote start 1. Unlock the vehicle doors using the
keyless access function. If the vehicle ’ s
doors are unlocked manually using the
key, the vehicle ’ s alarm system will trigger
(if the alarm system is armed prior to
activating the remote engine start system)
and the engine will turn off. Perform either
of the following procedures to disarm the
alarm system. Refer to “ Alarm system ”
F 2-25.

& Pre-heating or pre-cooling
the interior of the vehicle Before exiting the vehicle, set the tem-
perature controls to the desired setting
and operation. After the system starts the
engine, the heater or air conditioning will
activate and heat or cool the interior to
your setting.

placing battery of access key ” F 11-50.7-16

Driving tips/Periodic inspections
operates at very high tempera-
tures.
. 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 recom-
mended maintenance services listed in
the maintenance schedule in the “ War-
ranty and Maintenance Booklet ” per-
formed at the specified time or mileage
intervals.
Driving in foreign countries When planning to use your vehicle in
another country:
. Confirm the availability of the correct
fuel. Refer to “ Fuel requirements ” F 7-3.
. Comply with all regulations and re-
quirements of each country.

Driving tips/Driving precaution
conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles.
. Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located under the
door latch on the driver ’ s side.
. Frequent driving of an AWD vehicle
under hard-driving conditions such as
steep hills or dusty roads will necessitate
more frequent replacement of the follow-
ing items than that specified in the
“ Warranty and Maintenance Booklet ” .
– Engine oil
– Brake fluid
– Rear differential gear oil
– Manual transmission oil (MT mod-
els)
– Continuously variable transmission
fluid (CVT models)
– Front differential gear oil (CVT
models)
. There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to “ Towing ”
F 9-12. Driving precaution 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. Winter driving & Operation during cold
weather Carry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
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 after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.8-6
