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 intercooler
performance when the outside tempera-
ture is high.
Water is sprayed for approximately 2
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.
CAUTION
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. Instruments and controls
