What if you called a Lexus parts person and asked what the amp rating is of that particular fuse. It least you'd narrow down the choices.

Well it was a good idea but I called & the answer was "look in your owner's manual". I told them that info is not in my owners manual & was then told to make a service appointment lol.

Great idea RX400h. Thanks

The fuse descriptions are very cryptic, aren't they?

 

If there is no description in the Owners Manual I'd use the spare fuses and try the spares.  Go for the biggest one (30A green) first....

 

Finding the correct page in the OM is a challenge in itself. 🤢

Yes very cryptic. I guess I can just pull every fuse one by one to see if any are blown. 

As a follow-up I want to check the fuses but I cannot figure out which fuse it is. I added pics of the fuses & the diagram on the underside of the fuse box lid. Any help on choosing the right fuse to look for would be appreciated. Thanks 

Has anyone had an issue with their rear window defroster not working? If it is a DIY fix without taking it in under the warranty I would do it & could save that hassle of taking it to the dealer. Thanks

It looks like the method used on RX models in general includes these steps:

• Turn off your vehicle and disconnect the battery. Doing this will help prevent electrical mishaps or electrocution.  This should not be necessary if replacing the bulb, only.
• Open the trunk. This will allow you to access the trim paneling on your vehicle.
• Remove trim lining. Using the small flat head screwdriver, pop out the plastic rivets holding your vehicle’s trim liners in place.
• Remove tail light from the assembly. You can do this by pinching the connector and pulling out the bulbs of each tail light.

Thanks RX400h. I found a youtube video showing the process & got the job done yesterday.

Your signature lists a 2016 ES350. I thought that you posted in the wrong section - sorry.

Oh crap, sorry for that, I forgot to change car type. I changed cars in the last week to the RX350

Perhaps check out these videos.

Thanks for your reply RX400H but they do not apply to the RX. 

Has anyone done a DIY replacement of a rear turn signal bulb? If so any tips would be appreciated. Thanks

Maybe Lexus has found out that the built-in from Lexus is not nearly as good as what smartphones deliver. The CT has Lexus navigation, but not worth using.

My previous car was a 2016 Lexus ES350 & I know where you are coming from regarding their nav system.

Do not use the built-in navigation. It is crab.

Takes 10 times longer to enter address than google maps on phone.

Smartphone GPS is far more up to date.

For free.

Where Lexus charge and arm and white of the eyes just to update it.

Thanks for the reply Lexus-CT. I don't need to worry on using the Lexus nav because there is not one in this SUV. I must use either Android Auto or Apple CarPlay. I would never have guessed a newer model Lexus to not be equipped with a nav system but here we are.

Thanks RX400h, I don't pick it up until Monday but I will go through your link & studdy. 

Hi All

I am a proud new (to me) owner of a 2022 RX350 & am hoping to get some guidance on how to use google maps on the SUV screen. So here is my situation, I do not have a data plan on my cell phone. I do have Android Auto on my cell phone. I have downloaded some google maps using wifi onto my cell phone using the offline method. Has anyone here been able to sync their cellphone to the SUV screen & use the preloaded google maps for navigation? If yes would you please as best you can, give me step by step instructions on how you did this? I take possession on Monday & am hoping to get this done while sitting at the dealership parking lot. Thanks

Thanks john, that is the same as the manual I read. I did interpret it wrong though. As you show, I need to push the cruise control lever forward for one second to activate the constant speed mode. I thought (wrongly) that to change the mode I needed to push the on/off button for one second. 

So here is what I found. I went to a site that has an archive of owners manuals & entered Lexus RX350 & as luck would have it they did have a manual. The only question is for what year the manual is for but I'm thinking for my issue the manual has not changed regardless of the year. 

The RX350 does have two cruise control modes, one called "constant speed" mode & the second called "vehicle to vehicle distance control" mode. When you first turn the engine on the default mode will be the vehicle to vehicle distance control mode but it can easily switched to the constant speed mode by holding down for one second the cruise control button.

Only use cruise control when driving at night on highways without other traffic or very little.

Thanks for the tip. Do you know the answer to my above question? Thanks

Three settings allow you to approach a leading vehicle by varying lengths before the adaptive cruise engages.  I use the shortest setting (lets me get closer to a leading vehicle before it starts to slow me down to that vehicle's speed), but if that car is going too slow, I just disengage the cruise until I pass it. There is no way to completely turn the adaptive portion off independently.  In moderate to heavy freeway traffic, I just keep the cruise control turned off.

Thanks for your reply Frank. I asked the same question on another Lexus site & 2 replies said the adaptive option can be turned off? 

Hi

I am looking to buy a used 2022 RX350 & have a question on the cruise control. I believe this SUV has adaptive cruise control (please correct if wrong) but can anyone tell me if there is an option to turn the adaptive option off so the cruise control works without the adaptive option? I use cruise control extensively but I can not stand the adaptive option while on a 4 lane highway & would never buy a vehicle that has only adaptive cruise control. Thanks

The oil has to meet the ILSAC GF-5 Motor Oil Standard.
ILSAC GF-5 Motor Oil Standard - A Smarter Motor Oil (motortrend.com)

I'd take a look at some of the 0W-20 oils at Walmart to see which ones meet or exceed (GF-6) this standard. I'm fairly certain that most of them meet GF-6. 

Thanks for the info RX400h. 

The owner's manual says to use 6.4 quarts of 0w20 engine oil. Does that mean synthetic or just regular? Thanks

If you are having questions and want facts, Call a Lexus Parts department and verify the parts you need and there part numbers and cost. Then you can research for a better price.

Gotcha, Thanks

The wiring may be of different lengths. They may be the same sensors on a Toyota Camry of the same years  😉

Here is what I am referring to when I say they look different. Thanks

Straight forward job, One bolt to remove the sensor from the wheel hub, Follow the wire back to connector, Disconnect and reverse the procedure to install. 

Thanks for your reply dcfish. Are all 4 sensors identical? I have been googling the issue & am having trouble finding my exact model (2004 Lexus ES330). It seems on some models the front & back sensors are very different looking.  Thanks

I think I need to replace one or more wheel speed sensors & am looking for any tips that would make the job easier? Thanks

1. Stop the vehicle and turn off the engine

   Tire pressure reset process cannot be done while the vehicle is moving.

2. Adjust the cold tire pressure in all four tires recommended on the tire placard

   The tire placard located on the door panel

3. Turn the ignition key to the “ON” position without starting the engine

   If your vehicle has an ignition button, press the POWER button twice without touching the brake pedal

4. Look for the TPMS reset button and press the button until the tire pressure indicator Blinks slowly three times. (It may be under the dash near the gas or brake pedal.)
    
5. Wait for several minutes with the engine switch in the “ON” position, to allow the system to record each tire’s pressure, then turn the engine off.

   Done!

Thanks RX400h
