Tire and Battery Care, when storing Sienna 2016 for 3 or more months
For the tires, put it up on blocks just enough to,keep,the tires off the floor, for the battery a float charger is the best too keep it active and not fry the battery, and it will help the vehicle to not loose any programming. I would also change the oil and filter and put some StaBil marine formula in the fuel tank and run it around the block just before setting it up.
