Leather upholstery is standard, along with automatic climate control, steering wheel audio controls, illuminated visor vanity mirrors and high-intensity discharge (HID) xenon headlamps.For 2006, The INFINITI G35 receives optional Rear Active Steer for the G35 coupe. Several option packages have been upgraded: Premium packages now include a Bluetooth hands-free phone system. Projector-beam bi-xenon headlights are now standard on the coupe. Automatic coupes with the Sport Suspension Package now wear the same aero package as manual-transmission versions.
