Intercooler water spray
switch (WRX-STI)
Pressing this switch causes water to be
sprayed into the intercooler. It can be
used to help maintain adequate intercool-
er performance when the outside temper-
ature 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, refill
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 (WRX-STI)$
section in chapter 11.
In cold weather (when you do not use
the intercooler 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.
