The diesel left-hand-drive European model without head-protecting side airbags was tested by Euro NCAP. Australasian specifications may vary and therefore models sold in Australasia might provide different levels of protection to those described on this page. The right-hand-drive model can be expected to provide comparable occupant protection to the left-hand-drive model.
The tested model of Mercedes-Benz Viano was introduced in Australia during 2005. This 5-star rating applies to 4 cylinder Vianos with head-protecting side curtains that became standard in 2006. Further technical information is being sought about V6 variants. Dual front airbags, side airbags and head-protecting side curtains for the front seats are now standard equipment in Australia. Antilock brakes (ABS), electronic brake distribution (EBD) and electronic stability control (ESC) are also standard. Intelligent seat belt reminders are fitted to both front seats. The front seat belt buckles are mounted on the seats and the upper anchorages are adjustable. These features improve the fit of the seat belt. Pretensioners are fitted to the front seat belts to reduce slack in the event of a crash. Three point seat belts are fitted to all rear seats. These provide better protection than a two point (lap) seat belt.
5 Stars. The Viano scored 12.79 out of 16 in the offset crash test. The passenger compartment held its shape well. Protection from serious leg injury was marginal for the driver and passenger. The vehicle scored 15.87 out of 16 in the side impact crash test. There was a slight risk of serious chest injury for the driver. A further two points were earned in the optional pole test, which was conducted by ANCAP.
