Intercooler water spray switch (WRX-

Pressing this switch causes water to be sprayed into

the intercooler. It can be used to help maintain ade-

quate intercooler performance when the outside tem-

perature is high.

Water is sprayed for approximately two seconds every

time the switch is pressed and then released.

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

(WRX-STi)" section 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.
