For enhanced safety, the front and second-row seat shoulder belts of the Toyota Sequoia have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The GMC Yukon doesn’t offer pretensioners for its second-row seat belts.
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 Yukon doesn’t offer knee airbags.
The Sequoia has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The Yukon doesn’t offer a whiplash protection system.
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 Yukon 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. A system to reveal vehicles in the Yukon’s blind spot costs extra.
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. GMC charges extra for Rear Cross Traffic Alert on the Yukon and the Yukon’s Rear Cross Traffic Alert does not include automatic braking.
The Sequoia’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Yukon doesn’t offer a driver alert monitor.
Both the Sequoia and the Yukon have standard driver and passenger frontal airbags, front side-impact 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.
