Tow with confidence.A heavy load calls for a robust tow bar. The X-Class towbar ensures your 4MATIC ute achieves its maximum 3.5t towing capacity (4MATIC only). The towbar’s intelligent wiring harnesses are seamlessly integrated into the vehicle’s on-board systems, while the ball is easily removed to reduce the length of the vehicle in non-towing environments. For those towing more than 750 kilograms, a trailer brake controller is recommended. It is a legal requirement when towing more than 2t.
