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 Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Ascent doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The Sequoia has a standard blind spot warning system that 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/Onyx/Limited/Touring offers a blind spot warning system.
To help make backing out of a parking space safer, the Sequoia has standard Rear Cross Traffic Alert and Parking Support Brake automatically engages the brakes to help avoid a collision. Only the Ascent Premium/Onyx/Limited/Touring offers Rear Cross Traffic Alert and the Ascent’s Rear Cross Traffic Alert does not include automatic braking.
Both the Sequoia and the Ascent have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 1030 to 1764 pounds more than the Subaru Ascent. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
