Secondary functions are logically located, but sometimes the markings aren't instantly clear – such as the rear vent window symbols and the 4WD controls. Power seat adjustments are made on the seat base rather than the traditional Mercedes pictograms on the door panels. The cruise control is still on a left-hand stalk, while the turn signals, high-beam headlights, and wiper/washers for the front and rear are all grouped on a thick, sturdy stalk that is completely hidden from view by the steering wheel supports. The GL450 is equipped with an unconventional column shifter that is easy to get used to.
