an additional four times. If the vehicle fails
to start after the additional attempts, the
remote engine start system will abort and
return to a non-activated state. &Remote start safety features
For safety and security reasons, the
system will fail to start and beep the horn
twice or shut down the engine during
remote start operation if any of the
following conditions occur. . The brake pedal is depressed before
the vehicle ignition switch is turned “on ”.
. The key was already in the ignition
switch.. The engine hood is opened.
. The vehicle ’s engine idle speed has
reached a level over 3,000 rpm.. The alarm is triggered by opening a
door or the rear gate.
NOTE . The security indicator light on the
combination meter will stop flashing
while under remote engine start opera-
tion, but the vehicle is still protected.. If the vehicle is entered during
remote engine start operation, the
system will not record entry in the
alarm history. &
Entering the vehicle while it
is running via remote start
1. Unlock the vehicle doors using the
remote keyless entry system. If the vehi-cle ’s doors are unlocked manually using
the key, the vehicle ’s alarm system will
trigger and the remote engine start system
will turn off. Inserting the key into the
ignition switch and turning it to the “ON ”
position or pressing the unlock button “
”
on the remote keyless entry transmitter
will disarm the alarm system. Refer to“ Alarm system ”F 2-15.
2. Enter the vehicle. Do not depress the
brake pedal.
3. Insert the key into the ignition switch
and turn to the “ON ”position. If the ignition
switch is accidentally turned to the“ START ”position, the system ’s “starter
anti-grind ”feature will prevent the starter
from re-cranking.
4. Depress the brake pedal. The remote
starter disengages, the vehicle ’s power
window features are re-enabled and the
vehicle will operate normally.
& Entering the vehicle follow-
ing remote engine start shut-down
An alarm trigger may occur if the vehicle is
opened by the remote keyless entry transmitter within a few seconds immedi-
ately following remote engine start shut-down. &
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
vehicle, the heater or air-conditioning will
activate and heat or cool the interior to
your setting. & Service mode
In service mode, the remote start function
is temporarily disabled to prevent the
system from unexpectedly starting the
engine while being serviced. ! To engage the service mode
Turntheignitionswitchtothe “ON ”
position, depress and hold the brake
pedal, then press and release the “
”
button on the remote engine start trans-
mitter three times. The system will pause
for 1 second and then flash the turn signal
lights and honk the horn three times
indicating that the system is in service
mode. When attempting to activate the
remote start system while in service
mode, the turn signal lights will flash and
the horn will honk two times and will not Starting and operating

Limited slip differential (LSD) (STI)
The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speeddriving.
CAUTION
. Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
. If one tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
. If you use a temporary spare tire
to replace a flat tire, be sure to
use the original temporary spare
tire stored in the vehicle. Using
other sizes will adversely affect
the LSD. Power steering
The power steering system operates only
when the engine is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
CAUTION
Do not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.
NOTE
Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble. Braking &
Braking tips
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
! When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing
the brake pedal to heat up the brakes. ! Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking. ! Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause

9-12In case of emergency
Engine overheating
WARNING
Never attempt to remove the radia-
tor 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 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 off the engine and get everyone
away from the vehicle until it cools down. & If no steam is coming from
the engine compartment
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to “Engine coolant ”F 11-12.
1. Keep the engine running at idlingspeed. 2. Open the hood to ventilate the engine
compartment. Refer to
“Engine hood ”
F 11-5.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If temperature gauge stays in the over-
heated zone, turn off the engine. Refer to“ Temperature gauge ”F 3-10.
4. After the engine has fully cooled down,
check the coolant level in the reservetank.
If the coolant level is below the “LOW ”
mark, add coolant up to the “FULL ”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 counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it. Towing
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following
procedures for safety.
WARNING
Never tow AWD models with the
front wheels raised off the ground
while the rear wheels are on the
ground, or with the rear wheels
raised off the ground while the front
wheels are on the ground. This will
cause the vehicle to spin away due
to the operation or deterioration of
the center differential.
