The Sienna Limited Premium FWD’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Odyssey doesn’t offer pre-crash pretensioners.

For enhanced safety, the front and middle seat shoulder belts of the Toyota Sienna are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Honda Odyssey doesn’t offer height-adjustable middle seat belts.

The Sienna offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Odyssey doesn’t offer all-wheel drive.

The Sienna Limited Premium has a standard Bird’s Eye View Monitor to allow the driver to see objects all around the vehicle on a screen. The Odyssey only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the Sienna and the Odyssey have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.

The Sienna’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Odyssey’s standard rear power window switches have to be held the entire time to open or close them fully.

The Sienna has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The Odyssey has an automatic headlight on/off feature standard only on the EX/EX-L/Touring/Elite.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Sienna has standard extendable sun visors. The Odyssey doesn’t offer extendable visors.

The Sienna Limited has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Odyssey offers an automatic rear view mirror, but its side mirrors don’t dim.

The Sienna has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the Odyssey EX/EX-L/Touring/Elite.
