Indeed. Most if not all wouldn't have spray booths etc. My local dealer subs out all sorts of work - paint/dents (both major work and smart repairs), wheel refurb, tyre fitting, wheel alignment, leather seat upholstery, windscreen fitting. But they would insist that genuine Lexus parts are used and up to Toyota repair standards.

The alarm siren has a battery backup. It is likely the battery is no longer holding charge and just consuming energy, and therefore the vehicle is constantly charging it.

The needles have been known to stick on the LS400 - a whack on top of the dash may free them.

If you don't have the service history book then I would sign up to My Lexus and add your vehicle. You should be able to see recent service history but you may find it incomplete or incorrect for early services as they weren't all put in a central database back in 2008. https://www.lexus.co.uk/owners/about-my-lexus/my-lexus-portal

I didn't think any UK Lexus vehicle had a panic button, although they are common in the US and other countries. Perhaps the key you have was a replacement not sourced by a Lexus dealer.

If you are in the EU, or your country adopts EU regulations, then the motor vehicle block exemption regulation prevents Lexus from withholding their initial 3 year manufacturer warranty provided any work performed was by a competent person using parts of similar quality to original - this is the reason why you don't have to use Lexus for servicing to maintain the initial warranty and it applies to repair work too. Lexus are required by law to make their special tools, repair manuals, diagnostic equipment and parts available to third party repairers. Having said that, you would be more confident that work carried out would be done correctly and with all original parts if you used a Lexus dealer - you need to decide if the extra cost of Lexus insurance is worth it.

1 - yes it can be disabled from the car directly. 2 - you would need to unlock the door using the mechanical key, open the bonnet and use the jump terminal to either use a jump starter or charge the battery. Using a jump starter to get into Ready mode and then letting the car charge the 12v battery is fine. 3 - The LBX is not at risk of the current method used to steal older Lexus models. No need to use Lexus insurance - they don't provide any benefits over other companies.

Only useful if you want to reduce sound or air pollution in an area later on in your journey. Otherwise, as you say, it is pointless and a very inefficient way to recharge the battery compared to plugging in.

That is normal. It will try and maintain the battery around 50% so you have capacity to store more energy if you are going down hill etc. and have enough spare energy to assist the petrol engine when needed.

Just depends what you want to store in there. Good to have the choice 👍

RTM 🤣

They are just there to help you navigate the controls. In your example you are in the driving assist settings page - here there are only two functions assigned to the 4-way control - if there is a dot there is no function. When you disable adaptive cruise control you get three dots as only one function is now available (video 4:04). These aren't user configurable - you cannot add functionality to the driving assist options page.

Not illegal just not recommended. All tyres have different characteristics under extreme conditions.

Yes, I believe it can only be displaying the vehicle’s speed via the wheel sensors not GPS.

No UK 400h cars have DRLs.

It won’t need reprogramming, I suspect the battery isn’t in correctly or it is flat (or possibly fake if it has come from eBay or Amazon). If you are sure it is working then press and hold unlock whist next to the car for 30+ seconds until the car responds.

VSC, not ASC. I don’t see why that would cause a battery drain, it would be powered off with the vehicle. Do not disable it, it is there is help you out in an extreme situation such as collision avoidance, not just wet weather grip, and is intrinsically linked to ABS. I suspect you have something else draining the battery. Possible the battery backup in the alarm system has failed and needs constant charging. I disagree. Using the vehicle daily, even for short runs is normally fine. It’s long periods of no use that is the issue. It would probably add up to an hour or more each week. My wife had a similar commute for a few years and her hybrids were fine.

Spoiler is bolt on. If you got a replacement lid from an IS200 that didn’t come with a spoiler then you would need to drill the holes.

Yes, for a series III IS250, but very few of those were sold. I suspect the ones you are seeing are from the series II (2006-2013) which would not be compatible.

Yes

On the face of it that sounds sensible. But marginal gains in multiple areas across 10,000s of vehicles adds up to quite a financial saving. There is also the space and weight saving that the smaller battery provides.

Not aware of a publicly available list of that detail.

They are different part codes but the new one shows as a substitution for the older code so should be compatible. I’ve not tried this myself so cannot confirm.

Not very rare, all series IV GS 450h F Sport vehicles in the UK have rear wheel steer.

What age?
