The 2006 Toyota Sienna comes in four trim levels — CE, LE, XLE and top-of-the-line XLE Limited; CE and LE seat seven or eight. LE, XLE and XLE Limited are eligible for all-wheel drive. The CE includes ABS, a rear air conditioner, CD player, telescoping steering wheel, dual-sliding doors with power windows and keyless entry. The LE adds driver lumbar, cruise control, heated power mirrors, privacy glass, a roof rack and a fold-flat front-passenger seat — most of this is optional on the CE. The XLE includes alloy wheels, power-sliding doors, a power liftgate, auto headlamps, tri-zone automatic climate control, power-adjustable front seats and a removable center console. The XLE Limited trim level gets larger 17-inch wheels, rear disc brakes, stability control, adaptive cruise control, a moonroof, leather upholstery, heated front seats, a CD changer, a park-assist system and rear window shades. All-wheel-drive models automatically receive 17-inch wheels, run-flat tires, stability control and upgraded brakes. Options include a rear-seat entertainment system, navigation system and power-folding third-row seat.
