Page 95 of your owners manual: Cancelling the system Open any of the doors using an ignition key or wireless door lock remote control. This cancels the system completely and the starter circuit will be reactivated at once.

You can buy 2 master keys and the matching chip from Sewell Lexus in Texas for $273.60, not including shipping, if you register with an acceptable car forum member name: http://lexus.sewellparts.com 0 I registered with my clublexus member name. Replace the chip in the keyless entry receiver behind the trim on the left side of the trunk and you are good to go.

Either 6.5 or 7.5 "should" work but 7.5 is better in that it will put slightly more tread in contact with the road. My 2000 LS400 Platinum Series came standard with the same 16"x7" wheels that were standard on the 2001-2002 LS430. The aftermarket wheels I use in the winter with snow tires are 16"x7.5" and they work just fine. 6.5" wide 16" wheels are more appropriate for narrower tires. The 90-92 LS400 can with 205/65-15" tires on 15"x6.5" wheels. From 1993 through 2002, the standard tire size on the LS was 225/60-16" on 16"x7" wheels.

I have purchased parts from Sewell Lexus a number of times - in person, online and by telephone since around 1998. Sewell is located in Dallas, Texas is due south of where I live in Kansas which is probably why total cost including shipping is especially low for me. Sewell often gives additional discounts to those who register on the Sewell website with a car forum member name. I do not know if Sewell gives discounts to members of this forum but I do know that they give discounts to registered members of http://www.clublexus.com

In what regard to you want an opinion? Whether or not the brake kit from a U.S. specification car will fit your car? About the prices? Toyodiy.com does not sell parts. I have assumed that the prices they show are full retail prices although sometimes the prices make no sense at all.

About the best I can do is provide the instructions in case you don't have them: http://drivers.lexus.com/t3Portal/document/om/OM30441U/pdf/2_109.pdf I suppose you could disconnect the negative cable from your car battery for a few minutes to see if that puts the radio into "off" mode.

Installing either is not going to void your warranty. I've used roof, trunk lid and hitch mounted bike racks and the only type I would ever use, now that I know the advantages and disadvantages of each type, is a hitch bike rack. I actually can't think of any advantages of a roof or trunk lid rack, other than they can be the cheapest, but some people think roof racks are "cool". Trunk lid racks can do damage - sure had that happen. Roof racks are horribly noisy when driving at normal highway speeds, difficult to get bikes on and you always have to worry about forgetting the bikes are on top and trashing them by driving into a garage, etc. A hitch mounted rack puts all the noise behind you ... easy to put the bikes on ... can be used to hold a bike while you work on it. The same place I bought the trailer hitch for my LS has one for your HS: http://www.etrailer.com/hitch-2012_Lexus_HS+250h.htm Prices for hitch mounted racks are all over the map. My simple one is 22 years old probably cost less than $50 back then. Here's a photo with it on my LS.

Rotors can usually be machined back to like new if their thickness is within the acceptable range. I've driven something like a million miles in cars with disk brakes and I have yet to replace a brake rotor. OEM parts are usually the "safe" choice. Brakes are kind of important.

The height adjustable footrests, available for about the past seven years for several Lexus models in a number of countries, are still shown on the Lexus UK website as an available accessory for the LS460/LS600h: http://www.lexus.co.uk/range/ls/accessories/interior.aspx Try contacting a Lexus dealer in the U.K.

These transmissions don't really require much maintenance. I have the fluid in mine changed every 30,000 miles and I know that is overkill. Photos of both my previous and current LS400's are in my gallery: http://us.lexusowner...157&tab=gallery The 2000 is very nice and I was surprised that I found it more pleasant to drive than the 2012 LS460L AWD I test drove last fall. It's going to be hard to part with it but, as it's value falls, its becoming a fender bender away from being totaled out.

300,000 to 500,000 miles if the engine and transmission has been maintained properly with fluid changes and not abused. The engine and transmission will likely outlast the body. No oil changes and the engine could be "done" by 100,000 miles like any other engine. Other component failures are what are usually the end of these cars - worn interiors, electrical glitches, crashes and body damage that "total out" old cars. As nearly perfect as my 2000 LS400 is at 152,000 miles, it's just a minor crash away from being totaled for insurance purposes. When a car is this old, you alway have to be prepared to buy another.

I sold my 1990 LS400 in 2003 after driving it from new until 183,500 miles. I bought an off-lease 2000 LS400 earlier in 2003 at 38,000 miles and have driven it to about 152,000 miles. It is is remarkable condition. The 1998-2000 5-speed transmission and the similar 2001-2003 LS430 5-speed transmission may be the most reliable and trouble free transmissions Toyota has ever made. Does your 98 LS have a full maintenance history? Has it had occasional transmission fluid changes?

This may just be the nature of the beast. A number of people have complained about the transmission getting a little confused in a situation like slowing down, turning a corner and then accellerating. IMO, part of it is due to the engine's torque characteristic and transmission shift program which "remembers" the previous few shift cycles. I believe that most of it, however, is due to drivers not pushing the accellerator down and actually momentarily backing off the throttle before they apply it, confusing the transmission ECU and then lurching forward. I do this too occasionally. My suggestion is to drive a couple of similar 98-00 LS400's cars in similar situations. How many miles on your 98?

It is normal on the 1998-2000 LS400 when the transmission is cold. Mine does the same thing.

I have wondered why the more complete maintenance schedules have been removed from the Lexus owners website. The simple one now there says the spark plug change interval for the 2004 IS300 is 60,000 miles: http://drivers.lexus...nts/41e2smt.pdf As the previous poster said, the CEL could have been caused by a loose gas cap. The spark plug change interval is much shorter on at least some 6-cylinder models. The change interval of the iridium plugs on my LS is 120,000 miles and the original plugs looked good as new when I had it done.

Has this car ever ran properly? If it has, the "missing" resister isn't the problem - there were several subtle variations of the gen 1 LS400 and it's not unusual to see unused connectors under the hood on some of the variations. I could speculate about a couple of issues that could cause the problem you are having but I won't do that. Where the heck are you located? I'll bet my indie former Lexus dealer mechanic could figure this out in a few minutes.

Just use the exact same type of OEM spark plug - maybe the exact brand and model plug that your car came with. Assuming you are not going to drive this car to 240,000 miles, you will never have to be concerned with this again.

I would use OEM spark plugs. I had the oriiginal spark plugs in my 2000 LS400 changed 32,000 miles ago at 120,000 miles and the original ones appeared to be in excellent condition. The engine didn't run any differently before of after spark plugs were changed.

My Nakamichi did the same thing until the balance control was resoldered - both channels were fine for days at a time and then the right channel would be garbled or dead for days at a time. Surely it is not the same problem. Mine has worked perfectly since it was repaired in March 2008.

Nevermind my prevous post. My 2000 LS400 hard copy repair manuals clearly shows that your original radio is a standard Pioneer head unit. I happen to have an electronic version of the relevent section -- see the attachment. be-226.pdf

According to the photos I have, the radio on the right is a standard 98-00 LS400 Pioneer head unit. A guy who used to be active in this forum told me in a PM that he was going to put a Nakamichi faceplate on his 98 LS400 Pioneer radio so maybe that is what your situation is. Give me the part number from your original radio and I will check. Also maybe upload photos of the fronts of the radios.

My virus checker flags your "photo bucket" address as a malicious website. Post the photo on this forum. Are both your original and new radios Nakamichi? The Nakamichi and Pioneer head units are not interchangable. The plug-ins are in different places on the back of the head units according to the photos I have of the back of my 2000 LS Nakamichi head unit and the back of a 98-00 LS Pioneer head unit.

It's possible that the problem could be the fuel pump but don't just throw money at it. Diagnose the problem. Having the service manuals are priceless. There is a diagnostic procedure for just about everything.

Get the part number off the sticker on your new radio head unit and look it up on http://www.toyodiy.com to see which Lexus model it is really for. The part number for the 1998 LS400 Nakamichi head unit is 86120-50570 according to toyodiy.com. Post the part number if you can't figure it and and I or someone else will look it up for you.

The HVAC filter is on the left side near the accellerator pedal. The arrow in the attached diagram points at it.
