Limiter
Function of the limiter
The limiter restricts the speed of the vehicle. To
reduce the speed to the set speed, the limiter
applies the brakes automatically.
You can limit the speed as follows:
R
Variable: for a short-term speed restriction,
e.g. in built-up areas
R
Permanent: for a longer-term speed restric‐
tion, e.g. in winter tyre mode
The variable limiter is operated using the corre‐
sponding steering wheel buttons (
/
page 243).
You can store any speed above 20 km/h up to
the maximum design speed or up to the set win‐
ter tyre limit. You can also perform settings
while the vehicle is stationary if the vehicle has
been started.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nise dangers (

page 230).
