Fu
nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed swiftly tothe set speed, the
limiter applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed limits, e.g. in built-up
areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving wi thwinter tyres fitted.
If yo ufa ilto adapt your driving style, the limiter
can neither reduce therisk of an accident nor
ove rride the la wsof ph ysics. It cannot take into
account road, weather or traf fic conditions. The
limiter is only an aid. You are responsible forthe
dis tance totheve hicle in front, forve hicle
speed, for braking in good time and forst ay ing
in lane.
Yo u can operate theva riable limiter with the
cruise control le ver.Yo u can store any road
speed abo ve20 km/h. You can also per form
settings while theve hicle is stationary if the
ve hicle has been star ted. Kickdown
If
yo u depress the accelerator pedal be yond the
pressure point (kickdown), the limiter is
switched topassive mode. The Limiter passive
message appears in the multifunction displa y.
Af ter completion of kickdown, theva riable lim‐
iter is activated again in thefo llowing situations:
R ifth e driven speed drops below thestored
speed.
R ifth estored speed is called up.
R ifyo ustore a new speed.

WARNING Risk of accident due to
unknown stored speed
If yo u call up thestored speed and this is
lo we rth an your cur rent speed, theve hicle
decelerates.
If yo u do not kn owthestored speed, the
ve hicle could decelerate unexpectedly. #
Take into account the tra ffic situation
before calling up thestored speed. #
Ifth estored speed is not known, store
th e desired speed again. Change into a lo
werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, you will make use of the braking ef fect
of the engine. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and wearing tooqu ickl y.
