Glad to hear that things are ok with your starter, at about 100,000 miles I switched to mobil one synthetic oil I have read that the lexus motor gets a lot of value from synthetic oil and it also takes half of the normal starting amps on the starter due to how well the oil lubricates the engine. I change my oil at 10,000 miles which is ok using synthetic oil I use 5w-30 weight. Something of interest mercedes, BMW,porsche and all Italian built sport cars use mobil one as the oil of choice since 2000 and some of them go 15000 miles before changing oil. Corvette has been using mobil one since around 1996 as factory fill.I was told that using synthetic oil it takes about half of the work load for the starter and the most wear on a motor is on startup. If any of the people who read these messages live in the cold climate mobile can still run free at 50 degrees below zero and still protect your motor. Starting your engine in the morning is the most wear it gets that is why all the german cars run synthetic oil from the factory to make them last and last.

I have a 98 LS400 that needs an upgrade on the Navigation system. I thought the upgrade is a hard-disk. Does anyone know whether the upgrade is a DVD or hard-disk and is that located in the truck on the passenger side? Thanks.

I have just learned from my local Lexus dealer that the latest NAV DVD version (2005) is available to upgrade my 2002 LS430. I know how to change out the DVDs but the dealership tells me that the vehicle's nav system has to be recalibrated as well. Is this for real or just a way of raising the price on the DVD?

Good advice on the Mobil One, I read most of the posts on the Starters that were failing. Lexus had a Recall out a few years ago on the 98,99 LS and it had to do with only the starter contacts. This is not a big Lexus problem. My first LS went 275000 miles and is still being driven by my friend and the starter has never been changed. I read on Club Lex that a Toyota certified Tech can change them in a half hour.

First I've heard of a "recalibration" needed. But there is a screen option for doing that, and the manual says hitting it and driving will do that, if necessary. But that is only necessary, after you install new tires.
I think your dealer is trying to get an extra $250 out of you to install it. I put mine in myself, and it works just fine - shows all the new streets in my town, etc. You can get them for $299 from Lexus-parts.com, and put it in yourself. Previous posts explain how to. It's painlessly easy. Takes 5 minutes. I did it on a coffee break at work.

I saw your message about the club lex toyota certified tech can change a starter in a lexus in about a half an hour. Maybe on the ES300 he can, but not the LS400. On the LS400 you have to take out the whole intake manifold and all the upper parts of the motor. A fast person could do it maybe 2-4 hours but if I am wrong on this where is the tech who can do it. Speaking of mobil one oil I run the synthetic mobil automatic transmission fluid in my lexus transmission I want to see if it makes a difference for making it last longer. BMW Mercedes, cadlliac,porsche and several other car manufactures are now using synthetic ATF in the transmission going 100,000 miles before changing the fluid. This should prove to be interesting if they hold up!!!!

Your LS auto trans was designed specifically to use the Toyota type auto fluid , it has specific friction modifiers for specific Toyota transmissions and not all Toyotas are to use it . Perhaps you should verify if Toyota recommends/oks this fluid in your Lexus . I know they recommend Mobil 1 motor oil for their engines ( saw a toyota promo at the dealer recently ) but their auto transmissions are a different story .

your are right the LS does use a type 4 fluid and since mine is a 91 LS the trans can still use mobil one auto trans fluid so far no problems I also put in a transmission cooler and a small power steering cooler to help keep down heat to these parts. As a salesman I spend 9-12 hours daily on the road including the south west desert and it really get hot there. I also pump the synthetic trans fluid every 20,000 miles just to make sure the trans always has fresh fluid as I do the power steering at the same time. As far as the engine oil I change it every 10-12 thousand miles since it is synthetic oil with no problems. My last toyota cressida went 400,000 miles same motor and trans using mobil one.A friend of mine pushed his 90 LS400 to 568,000 miles and still running using mobil one. And the car is still on the road past 600,000 miles with very few problems. There is a guy in the Southern California with 800,000 miles on a 90 LS400 same engine and 1 trans at 550,000 changed out now lets see some other car manufactures that can do that.
#1893 of 2081 94 LS 400 intergrated phone
Feb 04, 2006 (10:39 am)
My aunt has a 94 LS 400, and recently, the intergrated phone in the center console has been beeping. She got really annoyed, and thought that just cuting the cord would make it go away. Aparently, that didn't work. Now it beeps everytime she leaves the car. Anyone know why it's doing this? The car was bought in '99, from a dealer, and it wasn't known if the phone was ever activated. If I try and just disassemble the center console and unplug all the phone's components, will the beeping go away? Any diagrams/instructions on how to disassemble out there?

On the early LS the main phone unit which controls the center console handset is in the trunk on the LHS below the tool kit and behind the trim cover . The unit is locked in and mine came with a key to release . The key was in the center console .
