Yo u can choose between two settings.
RStandard: normal sy stem sensitivity
RSensitive: higher system sensitivity. The

Traf fic Sign Assist
Fu nction of Traf fic Sign Assist
Tr af fic Sign Assist detects traf fic signs using
multifunction came ra1. It assists youby dis‐
playing de tected speed limits and overtaking
re strictions in the instrument clus ter. Since
Traf fic Sign Assist also usesthe data
st ored in the navigation sy stem, it can update
th e display in thefo llowing situations without
de tecting traf fic signs:
RWhen theve hicle changes roads, e.g. slip
ro ad or mo torw ay ex it.
RWhen a village or town boundary is passed
which is stored in the digital map.
The camera also de tects traf fic signs wi tha
re striction indicated byan additional sign (e.g.
re lating towe t conditions).
Wa rning when the maximum permissible
speed is exceeded
The sy stem can warnyou if you unin tentionally
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. You
can specify whe ther thewa rning is tobe just a

ra dar sensors tomonitor the area up to130ft
(40 m) behind your vehicle and 10ft(3 m)
directly next to yourvehicle.
If a vehicle is de tected at speeds ab ove appr ox‐
imately 8 mph (12 km/h) and this vehicle subse‐
qu ent lyenters the monitoring range di rectly next
to yo urvehicle, thewa rning lamp in the outside
mir ror lights up red.
If a vehicle is de tected close to yourvehicle in
th e lateral monitoring range and youswit chon
th e turn signal indicator in the cor responding
direction, a warning tone sounds once. The red
wa rning lamp in the outside mir rorflashes. If the
turn signal indica torre mains on, all other de tec‐
te dve hicles are indicated only bytheflashing of
th ere dwa rning lamp.
If yo uove rtake a vehicle quickl y,no warning is
given.
0071 WARNING Risk of accident despite Blind
Spot Assist
Blind Spot Assist does notreact tovehicles
approaching and overtaking you at a greatly
di fferent speed.
As a result, Blind Spot Assist cannot warn
drivers in this situation.
00BBAlw ays pay careful attention tothe traf‐
fi c situation and maintain a safe dis‐
ta nce at the side of theve hicle.
Blind Spot Assist and Active Blind Spot Assi st
are only aids. They may failto detect some vehi‐
cles and are no substitute for attentive driving.
Alw ays ensure that there is suf ficient dist anceto
th e side forot her road users and obs tacles.
Sy stem limitations
The sy stem may be limited in thefo llowing situa‐
tions:
Rth e sensors are dirty or co vered
Rpoor visibility, e.g. due tofog, heavy rain,
snow or spr ay
Rnarrow vehicles, e.g. bicycles, are within the
monitoring range
Wa rnings may be issued in er ror when driving
close tocrash barr iers or similar solid lane bor‐
ders. Warnings may be inter rupte d when driving
alongside long vehicles, e.g. truc ks,fo r a pro‐
longed time.
Blind Spot Assist is not operational when reve rse
ge ar is engaged.
Fu nction of braking applications (Active
Blind Spot Assist)
If Ac tive Blind Spot Assi stdetects a risk of a side
impact in the monitoring range, a cours e-cor‐
re cting brake application is car ried out. This is
designed tohelp youav oid a collision.
The course-cor recting brake application is availa‐
ble in the speed range between appr oximately
20 mph (30 km/h) and 125mp h (200 km/h).
