Information on the permanent limiter
If th eve hicle should ne verexc eed a specific
speed (e.g. for driving in winter tyre mode), you
can set this speed with the permanent limiter.
Yo u do this by limiting the speed between
16 0 km/h and 240 km/h in the multimedia sys‐
te m (/ page179).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you
confirm the message, display messages no lon‐
ge r appear until you swit choff theve hicle. The
speed will only be displa yed again once theve hi‐
cle has been restar ted or if the set speed is
ch anged.
The permanent limiter does not swit chtopas‐
sive mode even du ring kickdown and the driven
speed remains below the set speed. Setting
