2010 Rx 450H - Just Bought It, Need Some Help!


Recommended Posts

Hope I'm posting in the right place. I just bought a ceritifed pre-owned 2010 RX 450h. I love it, but a couple of questions as I get to know the car.

1) The rain sensor seems to not work. I set the wipers to what on another car would be "intermittent" but the wipers never come on. Am I missing something, am I a dummy? Or should I just get the dealer to replace the sensor?

2) Any way to turn off the seatbelt warning chime?

Thanks for any help!

Sometimes on my '08 the rain sensor doesn't start unless I put the selector on the regular setting and let it sweep a couple of times. Then, when I move it back to rain sensor, it works.

Hi Jason and welcome to the LOC. We're glad your here.

Bob is right. For some strange reason, known only to some Lexus engineer who must be just hanging on for retirement, all Lexus models, including the 2005 ES330 I used to have, still have the same wiper system. I leave my wiper setting in the auto rain sensing mode. They will come on almost instantly with just a sprinkle. The only time I consistantly have to start the wipers manualy is when I get in the car after having shut it off. The wipers, again for an unknown reason, will not come on automaticaly. I have to put the lever down to the first manual stage and then they will operate perfectly.

As far as the seat belt warning chime, the answer is no. The seat belt warning chime is activated by sensors in the bottom seat cushion. I hope by way of asking your question that your implying you don't wear seat belts? I had a accident last October and was very glad I had mine on.

For the wiper rain sensor, I was much happier after disconnecting the rain sensor plug behind the rearview mirror. It now oprates like a normal car and I have control over the intermittent speed.

The best way to turn off the seatbelt chime is to wear your seatbelt!

wow thanks guys. I have the same problem as the OP on the Rx400H I have just bought. And I was going to ask them to replace the rain sensor. I will try that 'fix'

I believe the rain sensor only works if the droplets are moving on the windshield. If it a light drizzle or you're stopped at a stop light / stop sign / just starting up from park, the droplets may not be moving and the sensor will not "see" them.

I like the sensing wipers and use the variable rate control as needed.

The seat belt chime stops after a bit, if you like driving without seat belts.
