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.
