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‐

Shortly before the set speed is reached, it is
shown in the driver displa y.When you confirm
