2006 Toyota Sienna Service and Repair Manual

This service and repair manual is written for the 2006 Toyota Sienna exactly as Toyota built it that year, from the 3.3L V6 (3MZ-FE) under the hood to the trim your van was sold as, so the specifications you work to are the ones Toyota released for this model year rather than a close approximation carried over from an adjacent one.

Known issues on the 2006 Sienna. Seven recalls are on federal record for this model year. Four of them are labeling recalls tied to load capacity: one because the GVWR is insufficient for the load carrying capacity of the vehicles; a second because incorrect load carrying capacity modification labels could result in the vehicle being overloaded; a third, from Southeast Toyota under Federal Motor Vehicle Safety Standard No. 110, covering tire selection and rims, because a driver may overload a vehicle which may increase the risk of a crash; and a fourth, from Gulf States Toyota under that same standard, where the recorded consequence is that this does not meet the standard requirements. A structure recall covers a cable that may break due to excessive corrosion, after which the spare tire may separate from the vehicle. Two seat recalls close the list: Access Options recalled vans built on Sienna chassis and equipped with VMI/RICON six-way power seat bases, where the seat occupant may be injured if the seat base pin were to break, and Southeast Toyota Distributors recalled seat heaters where, if damaged, the copper strand heating element may short circuit, increasing the risk of a fire. Owners have submitted 1,284 complaints for the year, and 116 technical service bulletins have been issued.

Tracing a front seat heater circuit, freeing a corroded spare tire cable, or checking the vehicle capacity weight on the tire and loading information label before you load the van up, you stay on Toyota's own procedure and the right specification for the 2006 Sienna.
