Worth knowing about the 2026 Sienna
- LED lighting. The low beam, high beam, fog light, front turn signal, brake light, tail light are sealed LED units with no user-replaceable bulb. A failure means replacing the assembly.
- Tire chains. The manual permits chains or cables, on the drive wheels only, fitted to the standard tire size. Chains for this size on Amazon →
- Tires. The owner's manual also lists P235/65R17 and P235/60R18 tires, and Toyota's 2026 release does not say which of the other grades use them.
- Torque. Tighten lug nuts to 76 ft-lbs in a star pattern with a torque wrench, and re-check after the first 50 miles. This figure is from the owner's manual; an impact gun will overshoot it.
- Roof load. The 150 lb roof limit is the dynamic figure for driving and includes the rack itself. It is not a limit for a rooftop tent when parked; the manual gives no static figure.
- Dimensions. Height is 69.7 in. with roof rails, and the XSE is 204.1 in. long.
