Sienna gets only minor changes for 2005. Models ascend through CE, LE, XLE, and leather-trimmed XLE Limited. All have a 230-hp V6 and a 5-speed automatic transmission. Front-wheel drive is standard. All but the CE are available with all-wheel drive. Antilock brakes and a tire-pressure monitor are standard. AWD versions have run-flat tires. All Siennas have a tilt/telescope steering wheel, remote keyless entry, and rear air conditioning. The sliding side doors have power-down windows. A power right-side sliding door is optional for LEs. XLEs and Limiteds come with dual power doors, power liftgate, and--new for '05--dual power front seats (vs. driver only). Seating for seven is standard and includes 2nd-row buckets and a 60/40 split folding 3rd-row bench that folds into the floor. CE and LE can carry eight via an optional 2nd-row bench; its middle section is sized for a child-safety seat. Standard on Limited are front torso airbags and head-protecting curtain side airbags covering all three seating rows. Other models offer packages that group the airbags with various features. Limiteds and AWD Siennas have 17-inch wheels vs. 16s. Exclusive to Limiteds are standard xenon headlamps, front/rear-obstacle warning, and radar cruise control. A navigation system and rear DVD entertainment are optional for most Siennas.
