NOTE
When taking your vehicle in for service,
it is recommended that you inform the
service personnel that your vehicle is
equipped with a remote engine startsystem. & Remote engine start trans-
mitter programming and pro-
grammable feature option
New transmitters can be programmed to
the remote engine start system in the
event that remote engine start transmitters
are lost, stolen or damaged. The remote
engine start system also has one pro-
grammable feature that can be adjusted
for user preference.
The remote engine start system can be
programmed to either make an audible
horn chirp upon remote start activation or not. Remote engine start transmitter pro-
gramming and feature programming can
be adjusted using the following procedure.
1. Open the driver
’s door (the driver ’s
door must remain opened throughout the
entire process).
2. Insert the key into the vehicle ’s ignition
switch and turn to the “ON ”position.
3. Locate the small black programming
button behind the fuse box cover, on the
driver ’s side left under the dashboard
panel.
4. Press and hold the black programming
button for 10 to 15 seconds. The horn will
honk and the turn signal lights will flash
three times to indicate that the system has
entered programming mode. At this point
you can proceed to either step 5 or step 6.
5. To program a remote engine start
transmitter: press and release the “
”
button on each transmitter. The horn will
honk and the turn signal lights will flash
one time to indicate a successful trans-
mitter learn each time the “
”button is
pressed. You can program up to eight transmitters.
6. To toggle the Horn Confirmation chirps
ON/OFF: depress and release the brake
pedal to toggle the feature. The horn will
chirp and the turn signal lights will flash
one time to indicate Confirmation Horn
Chirps are “OFF ”. The horn will honk and the turn signal lights will flash 2 times to
indicate Confirmation Horn Chirps are“
ON ”. Depressing the brake pedal repeat-
edly will toggle the feature ON or OFF
each time.
7. To exit the remote engine start trans-
mitter and feature programming mode,
turn the ignition switch to the “LOCK ”
position, remove the key from the ignition
switch and test operation of the remote
engine start transmitter(s) and horn con-
firmation feature.
& System maintenance
! Changing the batteries
CAUTION
. Do not let dust, oil or water get on
or in the remote engine start
transmitter when replacing the
battery.
. Be careful not to damage the
printed circuit board in the re-
mote engine start transmitter
when replacing the battery.
. Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them.
. There is a danger of explosion if

an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
. Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
The two 3-volt lithium batteries (modelCR-1220 ) supplied in your remote engine
start transmitter should last approximately
3 years, depending on usage. When the
batteries begin to weaken, you will notice
a decrease in range (distance from the
vehicle that your remote engine start
system operates). Follow the instructions
below to change the remote engine start
transmitter batteries.
1. Carefully pry the remote engine start
transmitter halves apart using a small flat-
head screwdriver.2. Remove the circuit board from the
bottom half of the case and slide the white
plastic battery holder out from under the
battery tab releasing the batteries. Re-
move the old batteries and replace with
new ones. Be sure to observe the (+) sign
on the old batteries before removing them
to ensure that the new batteries are
inserted properly (battery “+ ” should be
pointed away from the transmitter circuit
board on both batteries).
3. Carefully snap the case halves back
together, then test the remote engine startsystem.

Pull the switch rearward to reduce the
initial LSD torque. When the lowest posi-
tion of the driver’s control center differen-
tial indicator light illuminates, the initial
LSD torque will be minimum. Under this
condition, only the Mechanical LSD torque
will limit the differential action.
CAUTION
. Do not operate the control switch
when a wheel slippage occurs.
Wait until the wheelspin has been
brought under control.
. Under any of the following con-
ditions after setting to the man-
ual mode, pull the center differ-
ential control switch to minimize
the initial LSD torque: .
When a temporary spare tire is
installed
. When your vehicle is towed
. When the vehicle is stopped
with the manual mode se-lected
NOTE . A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cor-
nering more difficult. Remember this
when adjusting the initial LSD torque.
In general, higher initial LSD torque
settings assist driving on slippery
roads and lower settings for non-slip-
pery roads. When the vehicle is stuck
in snow or mud, setting the initial LSD
torque to the maximum will help to free
the vehicle.. The setting of the initial LSD torque
will remain even when the auto mode is
selected or the ignition switch is turned
to the “LOCK ”position. However, the
initial LSD torque will be minimized
when the battery is disconnected andreconnected.. During cornering or when making
turns (especially when going into the
garage), the rotational difference be-
tween the front and rear wheels may cause a braking effect accompanied by
vibration and noise. This does not
indicate a problem. The phenomenon
will disappear when setting the initial
LSD torque to the minimum.
In the auto mode, it controls the initial
LSD torque automatically. While in the
auto mode, this phenomenon some-
times occurs depending on the driving
condition, however, it does not indicate
a problem..
Use the center differential indicator
light only as a rough indication of the
initial LSD torque.. If you operate the center differential
control switch while quickly accelerat-
ing or turning a tight corner, you may
feel slight shocks. This is due to
differential action by the center differ-
ential and does not indicate a problem. & Temporary release
When the driver stops the vehicle and
pulls the parking brake lever after manu-
ally setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator on the combination meter
continues to show the driver ’s selected
initial LSD torque. When the driver re-
leases the parking brake lever, the initial
LSD torque set by the driver is restored. Starting and operating

8-6Driving tips
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 winterstarts.
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.
SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.
Washer Fluid Con- centration Freezing Temperature
30% 10.4 8F( 12 8C)
50% 48F( 20 8C)
100%
49 8F( 45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block thenozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.

brake suddenly and keep driving
straight ahead while gradually redu-
cing speed. Then slowly pull off the
road to a safe place. Otherwise an
accident involving serious vehicle
damage and serious personal injury
could occur.
Check the pressure for all four tires
and adjust the pressure to the COLD
tire pressure shown on the vehicle
placard on the door pillar on thedriver’s side. If this light still illumi-
nates while driving after adjusting
the tire pressure, a tire may have
significant damage and a fast leak
that causes the tire to lose air
rapidly. If you have a flat tire, replace
it with a spare tire as soon aspossible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
Do not inject any tire liquid or aerosol tire sealant into the tires, as
this may cause a malfunction of the
tire pressure sensors.
If the light illuminates steadily after
blinking for approximately one min-
ute, promptly contact a SUBARU
dealer to have the system inspected.
Jump starting
WARNING
. Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or thevehicle.
If battery fluid gets on you,
thoroughly flush the exposed
area with water immediately. Get
medical help if the fluid has
entered your eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and obtain immediate medicalhelp.
Keep everyone including chil-
dren away from the battery.
. The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting.
. Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
. Whenever working on or around
a battery, always wear suitable In case of emergency

eye protectors, and remove metal
objects such as rings, bands or
other metal jewelry.
. Be sure the jumper cables and
clamps on them do not have
loose or missing insulation.
Do not jump start unless cables
in suitable condition are avail-able.
. A running engine can be danger-
ous. Keep your fingers, hands,
clothing, hair and tools away
from the cooling fan, belts and
any other moving engine parts.
Removing rings, watches and
ties is advisable.
. Jump starting is dangerous if it
done incorrectly. If you are un-
sure about the proper procedure
for jump starting, consult a com-
petent mechanic.
When your vehicle does not start due to a
run down (discharged) battery, the vehicle
may be jump started by connecting your
battery to another battery (called the
booster battery) with jumper cables. &
How to jump start
1. Make sure the booster battery is 12
volts and the negative terminal isgrounded.
2. If the booster battery is in another
vehicle, do not let the two vehicles touch.
3. Turn off all unnecessary lights and accessories.
4. Connect the jumper cables exactly in
the sequence illustrated.

(1) Connect one jumper cable to the
positive (+) terminal on the discharged
battery.
(2) Connect the other end of the
jumper cable to the positive (+) term-
inal of the booster battery.
(3) Connect one end of the other
cable to the negative () terminal of
the booster battery.
(4) Connect the other end of the cable
to the strut mounting nut of the vehicle
with the discharged battery.
Make sure that the cables are not near
any moving parts and that the cable
clamps are not in contact with any othermetal.
5. Start the engine of the vehicle with the
booster battery and run it at moderate
speed. Then start the engine of the vehicle
that has the discharged battery.
6. When finished, carefully disconnect
the cables in exactly the reverse order. In case of emergency
