The Honda Odyssey has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Sienna doesn’t offer a front passenger side knee airbag.
Using vehicle speed sensors and seat sensors, smart airbags in the Odyssey deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Odyssey’s side airbags will shut off if a child is leaning against the door. The Sienna’s side airbags don’t have smart features and will always deploy full force.
The Odyssey has a standard Whiplash Mitigation Front Seat Design, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Mitigation Front Seat Design system moves the headrests forward to prevent neck and spine injuries. The Sienna doesn’t offer a whiplash protection system.
Both the Odyssey and the Sienna 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available rear parking sensors.
