For enhanced safety, the front seat shoulder belts of the GMC Sierra 1500 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 Chevrolet Silverado Limited doesn’t offer height-adjustable seat belts.
Over 200 people are killed each year when backed over by motor vehicles. The Sierra 1500 offers optional Rear Cross Traffic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Silverado Limited doesn’t offer backup collision prevention brakes.
The Sierra 1500’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Silverado Limited and is only available on Silverado Limited LTZ/High Country.
Both the Sierra 1500 and the Silverado Limited have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available four-wheel drive, blind spot warning systems, around view monitors and rear cross-path warning.
