Both the Yukon XL and Sequoia have child safety locks to prevent children from opening the rear doors. The Yukon XL has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Sequoia’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Yukon XL (except SLE with front bench seat) has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Sequoia doesn’t offer front seat center airbags.
Full-time four-wheel drive is optional on the Yukon XL. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Sequoia.
A passive infrared night vision system optional on the Yukon XL Ultimate helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Sequoia doesn’t offer a night vision system.
Both the Yukon XL and the Sequoia have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front 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, blind spot warning systems, around view monitors, rear cross-path warning and available driver alert monitors.
