The previous Mazda3's cabin was starting to show its age, but the redesigned interior for 2010 features significant revisions that result in a contemporary cabin. The gauges have red illumination, and there's a dash-top screen that shows radio and air-conditioning settings. With the optional navigation system, the Mazda3 gets another screen for map information. The navigation system is operated by a cluster of buttons on the right side of the steering wheel.

With front bucket seats and a rear bench, the Mazda3 has room for five people. Interior features include:  

• Standard cloth seats
• Standard 60/40-split rear seat
• Standard CD stereo with auxiliary input jack
• Optional air conditioning
• Optional cruise control
• Optional remote keyless entry
