The SLK has features the Z3 doesn't yet offer but probably will, like side airbags and a «
child seat recognition system» to keep the passenger - side airbag from firing; and standard features that are optional on the Z3, like traction control and leather upholstery.
Standard equipment includes new, fibre - reinforced roll - over bar, two - stage driver and front passenger airbags, headbags, thorax airbags, seat belt tensioner with degressive belt force limiters, NECK - PRO crash - active head restraints, automatic
child seat recognition, three - stage ESP ® and also ATTENTION ASSIST drowsiness detection.
The front passenger seat can additionally be fitted with automatic
child seat recognition, which dispenses with the previous transponder in favour of a weight mat.
The front passenger seat can also be fitted with automatic
child seat recognition, which now works by a weight mat, enabling any child seat to be used — the airbag is automatically deactivated when a child seat is fitted, and reactivated once it has been removed.
