The new R-Class also scores heavily as a family car. Junior family members will benefit from the extraordinarily generous interior space, with room for up to three child seats in the second seat row. The two outside seats are fitted with ISOFIX child-seat anchorage points, which enable the seats to be anchored directly to the vehicle chassis. Even when installing a child seat on the front-passenger seat, the highest level of safety is provided: the optional child-seat recognition system automatically deactivates the front-passenger airbag as soon as it detects a child seat on the front-passenger seat. All you need is a special child seat equipped with a transponder (available from the Mercedes-Benz accessories range). As you see, not even a large family will stretch the R-Class to its limits.
