There should be two litle groves on the clear part where the light shines through. Get a small flat blade screw driver and pop it out. Place a rag between the plastic and your screw driver cause it could damage the plastic

You can remove the head light and try to blow dry it.....but removing it aint so easy. If the car is still under warrenty take it back ot the dealer, obiously it has a seal leaking and water is finding its way in there.

check your idle control motor

plain and simple......yes...yes it does, so if your bluetooth or sat nav unit *BLEEP* themselves, good luck, sat nav unit costs a bit lol

Heard of a few problems with people purchasing aftermarket pads for the RX models. They complain of more brake squeal, worse feeling peddal etc. The reason the orginal pads run out so quick is because the pads use are a soft compound pad and usually only last about 20,000kms. Lexus have recently brought out a new brake pad for the RX models which is a lot better, lasts longer and dosent leave as much brake dust on your rims. Ring your dealership and ask for the upgraded brake pad set for your vehice.

If you are talking about the Service screen on the touch screen, dont mess around with it, its for technicians to diagnose problems with your units...nothing else! As for your LPS, only way i know of is via doing it at the dealership.

Nope, should be heaps of info on the net for it

Is it still under warranty? If so, take the car to a dealership, show them the problem and it should be replaced under warranty

changing your wheel size will alter your speedo readings.

Main rattle for the IS250 is the Dash, which is about a day fix job. Seat belt rattle? try turning the buckle around the right way. Never heard of the rear window rattle, so i suggest all of you that are "fearing" the rear window rattle, relax. As for the moon roof, im guessing its doing it when its open...wind will cause stuff to move around.
