In addition to 4MATIC permanent all-wheel drive, standard equipment includes a hill start assistant, and Downhill Speed Regulation). Standard equipment also includes COLLISION PREVENTION ASSIST and ATTENTION ASSIST driver drowsiness detection. The radar-based COLLISION PREVENTION ASSIST operates at speeds between 20 and 155 mph and recognizes when the distance to the vehicle in front is decreasing. It can also recognize stationary objects. If there is an imminent risk of a collision, the system emits a visual and acoustic warning to alert the driver and prepares Brake Assist for the most immediate possible braking response, which is initiated as soon as the driver applies the brakes.
A new option is the Power EASY-ENTRY system for access to the third seat row. The Parking Assist package for the GL350 BlueTEC and GL450 features PARKTRONIC with Active Parking Assist for automatic maneuvering in and out of parallel parking spots, plus the new surround view camera which uses image data from four cameras at the front and rear of the vehicle and in the exterior mirror casings to calculate a bird's eye view of the vehicle and its surroundings, and shows this and other perspectives on the large COMAND display. The On- and Off-Road package, available as an option for the GL450 and GL550, enhances handling and safety with six programs, delivering optimum driveline control across the most diverse conditions on the road and on rugged terrain.
