Lexus gives the LS 430 a midcycle freshening for 2004. Along with mild exterior revisions, the LS gets a number of new standard features, including a six-speed automatic transmission (with a manual-shift gate), adaptive headlights that swivel during turning maneuvers, knee airbags for the driver and front passenger and a moonroof. New options include the Pre-Collision system, which uses radar to detect an avoidable collision, and prepares for impact by tightening up the seatbelts, switching to sport mode on air suspension-equipped vehicles and activating maximum braking pressure. Among the other highlights are SmartAccess, which allows the driver to start up the LS without inserting a key; 18-inch wheels as part of the Sport Package; and a rear backup camera, expanded voice recognition functionality and Bluetooth hands-free phone compatibility on vehicles with the navigation system. An upgraded Mark Levinson stereo now offers seating position-optimized sound, and satellite radio is a new dealer-installed option.
