If yo u wish tolimit theve hicle speed perma‐
nently toa specific value (e.g. for driving on win‐
te r tyres), you can set this speed with the per‐
manent 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 (→ page183). Shortly before
the set speed is reached, it
appears in the multifunction displa y.When you
confirm the message with %, display mes‐
sages no longer appear until you swit choff the
ve hicle. The speed will only be displa yed again
once theve hicle has been restar ted.
The permanent limiter does not switch topas‐
sive mode even du ring kickdown and the driven
speed remains below the set speed.

in there ar bumper. Parking Assist PARKTRONIC
indicates visually and audibly the dis tance
between your vehicle and an object.
Pa rking Assist PARKTRONIC is on lyan aid. It is
not a substitute foryo ur attention tothe sur‐
ro undings. The responsibility for safe manoeu‐
vring and parking remains with you. Make sure
th at there are no persons, animals or objects in th
e manoeuvring area while manoeuvring and
parking in/exiting parking spaces.
In thest andard setting, an intermit tent wa rning
to ne sounds from a di stance of appr oximately
0.3 m toan obs tacle. A continuous tone sounds
from a di stance of appr oximately 0.2 m. You can
set thewa rning tone in the multimedia sy stem
so that it will sound earlier at a greater dis tance
of appr oximately 1.0 m (→ page 201).
