3-10Instruments and controls/REV indicator light and buzzer (STI)
&Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON ”position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “Engine overheating ”F9-
12. REV indicator light and buz-
zer (STI)
The REV alarm system has the following functions. .
When the engine speed reaches the
level that was previously set, the REV
indicator light illuminates to inform you. At
this time, a buzzer also sounds if the
buzzer setting is activated. . Whenever the engine speed enters the
red zone of the tachometer, the REV
indicator light flashes.
If you press the trip knob, the odometer/
trip meter will show the engine speed that
has already been set.

3-34Instruments and controls/Front fog light switch
Front fog light switch (if equipped)
The front fog lights operate only when the
light switch is in the“”position.
However, the front fog lights turn off when
the headlights are switched to high beam.
To turn on the front fog lights, turn the front
fog light switch on the turn signal lever
upward to the “
”position. To turn off the
front fog lights, turn the switch back down
to the “OFF ”position.
The indicator light on the combination
meter will illuminate when the front fog
lights are illuminated. Wiper and washer
WARNING
In freezing weather, do not use the
windshield washer until the wind-
shield is sufficiently warmed by the
defroster.
Otherwise the washer fluid can
freeze on the windshield, blocking
your view.
CAUTION
. Do not operate the washer con-
tinuously for more than 10 sec-
onds, or when the washer fluid
tank is empty. This may cause
overheating of the washer motor.
Check the washer fluid level
frequently, such as at fuel stops.
. Do not operate the wipers when
the windshield or rear window is
dry. This may scratch the glass,
damage the wiper blades and
cause the wiper motor to burn
out. Before operating the wiper
on a dry windshield or rear
window, always use the wind-
shield washer.

tight for the accessory power
outlet, this can result in a poor
contact or cause the plug to get
stuck. Only use plugs that fit
properly.
. Use of an electric appliance in the
accessory power outlet for a long
period of time while the engine is
not running can cause batterydischarge.
. Before driving your vehicle, make
sure that the plug and the cord
on your electrical appliance will
not interfere with your shifting
gears and operating the accel-
erator and brake pedals. If they
do, do not use the electrical
appliance while driving. &
Use with a cigarette lighter (if equipped)
To use the accessory power outlet below
the climate control as a cigarette lighter
socket, purchase the cigarette lighter plug,
which is an optional accessory. A cigarette
lighter plug is available from your
SUBARU dealer.
The cigarette lighter operates only when
the ignition switch is in the “ON ”or “Acc ”
position.
To use the cigarette lighter, push in the
knob and wait a few moments. It will
automatically spring up when ready foruse.
WARNING
To avoid being burned, never grasp
the lighter by the end with the
heating element. Doing so could
result in injury and could also
damage the heating element.
CAUTION
. Do not hold the lighter pushed in,
because it will overheat.
. The electrical power socket lo-
cated in the center console is
originally designed to use a gen- uine SUBARU cigarette lighter
plug. Do not use a non-genuine
cigarette lighter plug in the sock-
et. Doing so may cause a short-
circuit and overheating, resulting
in a fire.
. If the socket is ever used for a
plug-in accessory such as a cell
phone, that may damage the
portion of the socket ’s internal
mechanism that causes a cigar-
ette lighter plug to “pop out ”
after its lighter element is heated.
Therefore, do not place a cigar-
ette lighter plug in a socket that
has been used, even once, to
power a plug-in accessory. Doing
so may cause the plug to stick
and overheat, creating a potential
fire hazard.

7-24Starting and operating/Limited slip differential (LSD) (STI)
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

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.
