The IS models' luxurious cabin features intelligently designed displays and controls that are easy to see and use. Bright, clear Optitron gauges and smartly integrated metallic trim, or available Bird's-eye Maple trim, contribute to an elegant yet sporty environment. Premium interior materials and meticulous attention to detail convey the Lexus identity.

The multi-information display located within the speedometer integrates a trip computer and an oil-maintenance reminder and system warnings, all grouped in one convenient location. When equipped with the available Intuitive Park Assist (IPA), the display can show a car icon with the location and distance of objects detected near the bumpers.
