Trucks usually have the jack and lug wrench behind the seat or under the hood, with the spare tire under the bed.
Do n't forget to check the pressure of the spare tire.
Toyota also recalled some 2011 Siennas for possible corrosion of the cable holding the spare tire to the underside of the vehicle.
Siennas also suffered from the same spare tire cable corrosion issue as the 2009 model.
The labeling and spare tire cable corrosion issues that plagued the 2009 and 2010 Siennas also affected some 2008 models.
