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 Ascent doesn’t offer a front passenger side knee airbag.
The Sequoia has a standard Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Ascent only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The Sequoia has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the Ascent Premium/Limited/Touring offers a blind spot warning system.
To help make backing out of a parking space safer, the Sequoia has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Only the Ascent Premium/Limited/Touring has a rear cross-path warning system.
Both the Sequoia and the Ascent 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, rearview cameras and available four-wheel drive.
The Toyota Sequoia weighs 1017 to 1755 pounds more than the Subaru Ascent. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
