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 toava lue
between 160 km/h and 240 km/h in the multi‐
media sy stem (→ page196).
Shortly before the set speed is reached, it
appears in the multifunction displa y.When you

once theve hicle has been restar ted.
The permanent limiter does not switch topas‐
