For enhanced safety, the front seat shoulder belts of the GMC Yukon XL are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X7 doesn’t offer height-adjustable front seat belts.
Both the Yukon XL and X7 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 X7’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 X7 doesn’t offer front seat center airbags.
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 X7 doesn’t offer a night vision system.
Both the Yukon XL and the X7 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, available all wheel drive and driver alert monitors.
