The front end is redesigned around a larger, more expressive grille, framed by an illuminated chrome surround. The headlights feature a star signature and incorporate the latest Digital Light technology, equipped with micro-LEDs that produce a beam that is 40% wider while reducing energy consumption by 50%.
At the rear, a decorative element visually connects the taillights, enhancing the vehicle’s width. This facelift also includes new body colors and alloy wheels up to 22 inches, including specific designs for the AMG line.

For off-road capabilities, the GLS offers dedicated functions such as the Free-Wheel mode to help extricate from sand and individual wheel height adjustment via the MBUX system.
