In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sequoia are reminded to check the back seat if they opened the rear door before starting out. The XC90 doesn’t offer a back seat reminder.
The Toyota Sequoia 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 XC90 doesn’t offer a front passenger side knee airbag.
Over 200 people are killed each year when backed over by motor vehicles. The Sequoia has standard Parking Support Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The XC90 doesn’t offer backup collision prevention brakes.
Both the Sequoia and the XC90 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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 and available four-wheel drive.
The Toyota Sequoia weighs 535 to 1798 pounds more than the Volvo XC90. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
