The Suburban 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 XL’s blind spot costs extra.
To help make backing out of a parking space safer, the Suburban has standard Rear Cross Traffic Alert and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. GMC charges extra for Rear Cross Traffic Alert on the Yukon XL and the Yukon XL’s Rear Cross Traffic Alert does not include automatic braking.
Both the Suburban and the Yukon XL have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, 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 all wheel drive.
