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

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.

Pe rm anent limi ter
If yo u wish tolimit the speed permanently to a
specific value (e.g. for driving on winter tyres),
yo u can set this speed with the permanent lim‐
iter.
Yo u do this by limiting the speed toava lue
between 160 km/h and 240 km/h in the multi‐
media sy stem (→ page193). Shortly before
the set speed is reached, it
appears in the multifunction displa y.When you

once theve hicle has been restar ted.

ise or unusual handling characteristics
While driving, pay attention tovibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tyres are damaged. If you suspect that a tyre is
defective, reduce your speed immediatel y.Stop
th eve hicle as soon as possible tocheck the
wheels and tyres for dama ge. Hidden tyre dam‐
age could also be causing the unusual handling

WARNING Risk of accident from dam‐
aged tyres
Dama ged tyres can cause tyre pressure loss.
As a result, you could lose cont rol of your
ve hicle. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. &
WARNING Risk of aquaplaning due to
insuf ficient tyre tread
Insu fficient tyre tread will result in reduced
tyre grip. The tyre tread is no longer able to
dissipate water.
This means that in heavy rain or slush the
ri sk of aquaplaning is increased, in particular
where speed is not adap tedto suit the condi‐
tions.
If th e tyre pressure is too high or too lo w,
tyres may exhibit dif fere nt le vels of wear at
dif fere nt locations on the tyre tread. #
Thus, you should regularly check the
tread de pth and the condition of the
tread across the entire width of all
tyres.
Minimum tread dep thfor:
R Summer tyres: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legally prescribed limit for
th e minimum tread dep thisreached. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, e.g.
prior toa long journey or driving off- road:
R Check the tyre pressure (→ page 402).
R Visual inspection of wheels and tyres for
damage.
R Check theva lve caps.
