Hi guys, Anton, you're right. Spoke with Lexus and as you say, its normal for the warning light to show because of the battery drain. Thanks a lot, all, sorted. Good Lexusing all!

Hi guys, Just reading your comments regarding your alternator problems on the IS220D/IS250 series. Anyone help with this? My problem is a little bit different than those above: my battery warning light stays on after I depress the engine switch twice (to ignition mode), when systems are checked. As soon as I start the car, the warning light goes off. Engine off, the battery voltage is 12.5v, engine running, no load (no lights on, etc) battery voltage is 13.25v. Any ideas?
