Sy
stem limitations
Te mp orary speed restrictions (e.g. for a cer tain
time or due towe ather conditions) cannot be
proper lyde tected bythe sy stem. The maximum
permissible speed applying for a vehicle with a
trailer is not de tected bythe sy stem. In these sit‐
uations you must adjust your speed yourself. &

speed
The speed adop tedby Active Speed Limit
Assi stmay be too high or incor rect in some
individual cases, su chas:
R Inthewe t or in fog
R When towing a trailer #
Ensure that the driven speed complies
with traf fic re gulations. #
Adjust the driving speed tosuit cur rent
traf fic and weather conditions. Fu
nction of route-based speed adaptation %
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
(/ page211).
Ro ute events ahead are:
R Bends
R T-junctions, roundabouts and tollst ations
R Turns and exits
R Traf fic jams ahead (only wi thLive Traf fic
( / page 358)) %
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 traf fic lights, as route-based speed adap ta‐
tion does not brake theve hicle toast andstill.
When route guidance is active, thefirs t speed
adjustment is car ried out automaticall y.Ifthe
turn signal indica tor is switched on, the selected
ro ute is confirmed and fur ther speed adjustment
is activated. 210
Driving and pa rking

When
the sy stem is actively steering, theè
symbol is shown in green in the multifunction
displa y.
If th e de tection of lane markings and vehicles
ahead is impaired, Active Steering Assist
switches topassive mode. The sy stem pr ovides
no support in this case. During the transition
from active topassive status, theè symbol is
shown as enlar ged and flashes yello w. Once the
sy stem is passive, theè symbol is shown as
gr ey inthe multifunction displa y.
Ste ering and touch de tection
The driver is requiredtokeep their hands on the
st eering wheel at all times and be able tointer‐
ve ne at any time tocor rect the course of the
ve hicle and keep it in lane. The driver must
ex pect a change from active topassive mode or
vice versa at any time. If
th e sy stem reaches a sy stem limitation or the
driver has not steered theve hicle for a consider‐
able period of time or has remo vedth eir hands
from thesteering wheel, the sy stem will,
depending on the situation, alert the driver
either with a visual warning or a visual and
acoustic warning. Display 1appears in the mul‐
tifunction displa y.
If th e driver does not steer theve hicle over a
long period, or has not take n hold of thesteering
wheel, a repeated warning tone sounds in addi‐
tion tothe visual warning message (depending
on the count ry). The
warning message does not appear or disap‐
pears if one of thefo llowing conditions are me t:
R The driver steers theve hicle.
R The driver presses a steering wheel button or
operates Touch Control.
Ac tive Steering Assist is only an aid. The driver is
re sponsible forth e dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane. Before changing lanes,
th e driver must make sure that the neighbouring
lane is free (glance over the shoulder).
Sy stem limitations
Ac tive Steering Assist has a limited steering tor‐
qu efo r lateral guidance. In some cases, the
st eering inter vention is not su fficient tokeep the
ve hicle in the lane or todrive past exits.
The sy stem may be impaired or may not function
in thefo llowing ins tances:
R In sno w,rain, fog, heavy spr ay, if there is
gl are, direct sunlight, greatlyvarying light
conditions, reflections or stro ng shado wson
th e car riag ew ay.
R Insuf ficient road illumination. 212

nction of the 360° Camera
The 360° Camera is a sy stem that consists of
fo ur cameras. The cameras co verth e immediate
ve hicle sur roundings. The sy stem assists you,
e.g. when parking or at exits with reduced visibil‐
ity.
The 360° Camera is only an aid. It is not a sub‐
st itute foryo ur attention tothe sur roundings.
The responsibility for safe manoeuvring and
parking remains with you. Make sure that there
are no persons, animals or objects etc., in the
manoeuvring area while manoeuvring and park‐
ing.
The sy stem evaluates images from thefo llowing
cameras:
R Reversing camera
R Front camera
R Two side cameras in the outside mir rors 226

Speed Limit Assi
stdetects speed limits wi th
multifunction camera 1and displa ys them in
th e instrument clus ter and optionally in the
head-up displa y.The camera also de tects speed
limits wi thare striction indicated byan addi‐
tional sign (e.g. in wet conditions). The sy stem
de tects stop signs, thereby pr eventing the
engine from being switched off bythe ECO
st art/ stop function.
Speed Limit Assist is only an aid. The driver is
re sponsible forke eping a safe dis tance tothe
ve hicle in front, forve hicle speed and for braking
in good time. The maximum permissible speed
also depends on factors su chasthero ad sur‐
fa ce and traf fic conditions. Wa
rning when the maximum permissible
speed is exceeded
The sy stem can warnyou if you unin tentional ly
exc eed the maximum permissible speed. Todo
th is, you can specify in the multimedia sy stem
by how much the maximum permissible speed
can be exceeded before a warning is issued. Yo u
can specify whe ther thewa rning is tobe just a
visual warning or an acoustic one as well.
