On two-tone models, the lower portions of the instrument panel and door trim panels are finished in a lighter shade for a more open feeling. Cloth and leather upholstery are offered. The ZX4 ST has unique woven fabrics or suede seating surfaces surrounded with leather trim.

A standard floor console houses the shifter, two cupholders, the parking brake, and controls for options such as traction control. An overhead console includes a sunglasses holder and a space for a garage door opener. Storage is also provided in the front doors, which feature molded-in bottle holders.

A CD player with MP3 capability is standard on all models. Models with the optional six-disc CD changer feature audio controls on the steering wheel.
