Optitron is the name used by Lexus to describe its electroluminescent gauges and displays, and they are lit by bright white LEDs for excellent readability, day or night. Almost all of the needles illuminate, dominated by the large tachometer and speedometer needles. Every single switch on the car is lighted for ultimate convenience. A new thin-film-transistor (TFT) multi-information color display delivers as many as 13 information and setting displays during driving.

New four-spoke tilt-and-telescope leather-and-wood steering wheels (heated on the uplevel versions) feature redundant controls for audio, information, cruise control, radar cruise control option, telephone, and a new brake-hold feature. To use the brake-hold feature, just come to a stop, push down the brake pedal, touch the button on the steering wheel, and the brakes stay on regardless of vehicle attitude until you touch the gas pedal.

The center stack of controls is beautifully integrated, as is every single piece of interior trim, and though there are lots of buttons, they are clearly marked in large type and lighted, so there will be little confusion after a couple of drives. The navigation display is large and bright, and the graphics are crisp and sharp. An auxiliary input is provided for MP3 players, such as the Apple iPod. The standard sound system is a 276-watt, 10-speaker system that sounds wonderful until you try the optional Mark Levinson system, which we think is the single best automotive sound system on the market.

The new Lexus LS is a big, roomy and comfortable luxury sedan, with generous interior dimension and 18 cubic feet of trunk space, enough for four sets of golf clubs.

The 460L version offers more room of course, and the option of a luxurious rear-seat setup with two reclining heated bucket seats, a cool box, sunshades, additional climate ducting, and dual-zone rear HVAC control. Yet another configuration, the executive class seating package, adds a folding table and a right rear seat with a built-in ottoman section, shiatsu massager, an extra air bag, and a rear roof-mounted 9-inch DVD screen and two sets of wireless headphones. No car manufacturer this side of a $350,000 Maybach offers this kind of rear-seat setup.
