Pe
rm anent limi ter
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 toava lue
between 160 km/h and 240 km/h in the multi‐
media sy stem (→ page 200).
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.

The following function is countr y-dependent
and only available in conjunction with the
Driving Assi stance Package. When Dis
tance Assi stDISTRONIC is acti ve,the
function adju ststh e speed depending on the
ro ute events ahead. Depending on the drive pro‐
gram selected, theve hicle negotiates thero ute
eve nt ahead in a fuel-s aving, com fortable or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
st ored speed. The set dis tancetotheve hicle in
front, vehicles de tected ahead and speed restric‐
tions ahead are take n into account.
Ro ute-based speed adjustment can byconfig‐
ured in the multimedia sy stem (→ page 206).
Ro ute events ahead are:
R Bends
R T-junctions, roundabouts and tollst ations
R Turns and exits
% When theto llst ation is reached, Active Dis‐
ta nce Assi stDISTRONIC adopts the speed as
th estored speed.
Also, the speed is reduced if the turn signal to
ch ange lanes is swit ched on and one of thefo l‐
lowing situations is de tected:
R Turning off at junctions R
Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts
and sets of traf fic lights, as route-based speed
adap tation does not brake theve hicle toast and‐
st ill.
When route guidance is active, thefirs t speed

turn signal indica tor is switched on, the selected
ro ute is confirmed and fur ther speed adjustment
