An optional Luxury Plus Package includes wood trim, perforated leather seating trim and heated and ventilated front seats, plus three-position memory for seats, steering wheel and outside mirrors, rain-sensing wipers, power tilt and telescopic steering column and auto-dimming outside mirrors.

Like all Lexus models, the IS offers its own version of the Mark Levinson® Premium Surround Sound Audio system, which is available in conjunction with the optional DVD touch-screen navigation system. This 14-speaker audio system features discrete 5.1 multi-channel playback with 7.1-channel speaker architecture. Its 10 amplifier channels provide 300 watts total output at 0.1 percent total harmonic distortion (THD). The Mark Levinson system plays conventional CDs and DVDs, plus MP3/WMA-formatted CDs. DVD movies can be viewed on the optional navigation system's color seven-inch touch screen when the parking brake is engaged.

The Lexus IS also offers a telematics system, Lexus Enform® with Safety Connect®, available by subscription. Complimentary one-year trial subscriptions are included on all purchases of new Lexus vehicles equipped with these features. Safety Connect is standard on all vehicles, while Lexus Enform with Safety Connect is on vehicles equipped with the optional Navigation system. The Lexus Enform and the Safety Connect response centers operate 24 hours a day, 7 days a week—every day of the year.

Lexus Enform vehicles are factory ready for subscriptions to a variety of innovative XM services including XM NavTraffic®, XM NavWeather™ and XM Sports and Stocks services. XM services require separate XM subscriptions. The XM Sports and Stocks service is included with an XM radio subscription. All XM services offer complimentary 90-day trial subscriptions.
