What is this for? on Lexus IS200

[Lexus_Sport]

Hi all,  

While checking all my fluids, came across this reservoir?  It says USE DOT 3 ONLY on it?

Your help is much appreciated

Is it not for your brake fluid, looks like brake master cylinder sitting under reservoir.

DOT 3 is one of many brake fluid designations, so would seem reasonable to say it's the brake fluid reservoir

The brake fluid should not be topped up as long as the level is between the low, and high markings.

The fluid level goes down as the brake pads ware, but when new pads are fitted the level will rise again. The fluid top should also not be removed unless you need to top up or replace the fluid as the fluid is hydroscopic (absorbs water readily from the atmosphere). This lowers it's boiling point, and causes internal corrosion of the brake system.

It should also be noted that brake fluid is a very good paint stripper so be very careful with handling it.

It isn't for the brakes, that is out of shot to the left of the photo.

That is for the clutch, which is hydraulically operated.
