Intercooler water spray switch (WRX-
STi)
Pressing this switch causes water to be sprayed into
the intercooler. It can be used to help maintain ade-
quate intercooler performance when the ambient tem-perature is high.
Water is sprayed for approximately two seconds every
time the switch is pressed and then released.
NOTE "The intercooler water spray warning light comes
on when the water level in the tank has dropped to
the lower limit. If the warning light illuminates, re-
fill the tank with water. The tank is located on the
right-hand side of the trunk. For the tank refilling
method, refer to the “Intercooler water spray” sec-
tion in Chapter 11." In cold weather (when you do not use the inter-
cooler water spray), keep the tank half-empty or
below in case the water freezes. A larger amount
of water could break the tank if it froze.

Do not press the switch when the warning light
is illuminated. If the switch is kept pressed
when the tank is short of water, the water pump
motor could overheat.
Mirrors
Always check that the inside and outside mirrors are
properly adjusted before you start driving. !
Inside mirror
1) Tab
The inside mirror has a day and night position. Pull the
tab at the bottom of the mirror toward you for the night
position. Push it away for the day position. The night
position reduces glare from headlights.

!Auto-dimming mirror/compass (if equipped)
1) Left button
2) Auto dimming indicator
3) Photosensor
4) Right button
The inside electronic compass mirror has an anti-glare
feature which automatically reduces glare coming
from headlights of vehicles behind you. It also con-
tains a built-in compass." By pressing and releasing the left button, the auto-
matic dimming function is toggled on or off. When the
automatic dimming function is on, the auto dimming in-
dicator light (green) located to the right of the button will illuminate. "
By pressing and releasing the right button, the com-
pass display is toggled on or off. When the compass is
on, an illuminated compass reading will appear in the
lower part of the mirror.
Even with the mirror in anti-glare mode, the mirror sur-
face turns bright if the transmission is shifted into re-
verse. This is to ensure good rearward visibility during reversing. " Photosensors
The mirror has a photosensor attached on both the
front and back sides. If the glare from the headlights of
vehicles behind you strikes the mirror, these sensors

detect it and make the reflection surface of the mirror
dimmer to help prevent you from being blinded. For
this reason, use care not to cover the sensors with
stickers, or other similar items. Periodically wipe the
sensors clean using a piece of dry soft cotton cloth or
an applicator. "
Compass calibration
1. For optimum calibration, switch off all nonessential
electrical accessories (rear window defogger, heater/
air conditioning system, spotlight, etc.) and ensure all
doors are shut.
2. Drive to an open, level area away from large metal-
lic objects or structures and make certain the ignition
switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then re-
lease, and the compass will enter the calibration
mode. “CAL” and direction will be displayed.
4. Drive slowly in a circle until “CAL” disappears from
the display (about two or three circles). The compass
is now calibrated.
5. Further calibration may be necessary should out-
side. Influences cause the mirror to read inaccurately.
You will know that this has occurred if your compass
begins to read in only limited directions. Should you
encounter this situation, return to step one of the
above procedure and recalibrate the mirror. "
Compass zone adjustment
Compass calibration zones
1. The zone setting is factory preset to Zone 8. Refer
to the “Compass calibration zone” map shown above
or one attached to the end of this manual to verify that
the compass zone setting is correct for your geograph-ical location.
2. Press and hold the right button for 3 seconds then
release, and the word “ZONE” will briefly appear and
then the zone number will be displayed.
3. Press the right hand button repeatedly to cycle the
display through all possible zone settings. Stop cycling
when the correct zone setting for your location is dis-

to prevent unintentional operation.
The mirrors can also be adjusted manually. !
Outside mirror defogger (if equipped)
Manual climate control system Semi-automatic climate control system
The outside mirror defogger shares the switch with
rear window defogger.
The outside mirror defogger operates only when the
ignition switch is in the “ON” position.
To turn on the outside mirror defogger, push the
switch. To turn it off, push the switch again. The indi-
cator light located on the switch lights up while the out-
side mirror defogger is operating.
The defogger will automatically shut off after about 15
minutes. If the mirror clears before that time, push the
switch to turn it off. It also turns off when the ignition
switch is turned to the “ACC” or “LOCK” position. If de-

NOTE "You will find the notation “USE WITH ”
on the air flow control dial plate.
This is intended to remind you to set the air inlet
selection lever in the “ ” position when de-
fogging the windshield.
Defogging with the air inlet selection lever set in
the “ ” position provides better defogging
performance than in the “ ” position. " When the dial is placed in the “ ” or “ ”
position, the air conditioner compressor operates
automatically regardless of the position of the air
conditioner button to defog the windshield quick-ly.
However the indicator on the air conditioner but-
ton will not come on.
Also, you cannot stop the air conditioner com-
pressor by pressing the air conditioner button. !
Air conditioner button (if equipped)
