All Siennas get standard front side airbags and curtain side airbags for 2006, and the top-line version is available with a power folding 3rd-row seat. Sienna comes in CE, LE, XLE, and leather-trimmed XLE Limited models. All use a 215-hp V6 and a 5-speed automatic transmission. All models are available with front-wheel drive and all but the CE are available with all-wheel drive. Standard seating is for seven via 2nd-row buckets and a 60/40 3rd-row bench that folds into a floowell. CE and LE can carry eight with an optional 2nd-row bench. Standard features include ABS, tilt/telescope steering wheel, and rear air conditioning. Power operation for the right-side sliding door is optional for LEs. XLEs and Limiteds come with dual power doors and a power liftgate. The curtain side airbags cover all seating rows; they previously were standard only on Limited models. Traction/antiskid control is standard on Limited and AWD models, optional otherwise. Limited exclusives include xenon headlamps, front/rear obstacle detection, and adaptive cruise control; these are joined for '06 by power folding door mirrors with turn signal lamps. The optional power 3rd-row seat is exclusive to the XLE Limited.
