Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your imme-
diate surroundings. You are always responsi-
ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there are no persons, animals or objectsint he area
in which you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in alimited manner:
R if the trunk lid is open
R in heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent light or LED
lighting (the display may flicker) R
if there is asudden change in temperature,
e.g. when driving into aheated garage in
winter
R if the camera lens is dirty or obstructed
R if the rear of your vehicle is damaged. In this
event, have the camera position and setting checked at aqualified specialist workshop
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, bicycle rack).

tAssist
General notes Blind Spo
tAssist uses aradar sensor system
to monitor the area sonboths ides of your
vehicle. It supports yo ufrom aspeed of
approximatel y20m ph (30 km/h). Awarning
display in the exterio rmirrors draws your
attentio ntovehicles detected in the moni-
tore darea. If youthen switch on the corre-
sponding turn signa ltochange lanes, yo uwill
also receive avisua land audibl ecollision
warning .For thi spurpose, Blind Spo tAssist
uses sensors in the rea rbum per.
Important safety notes Blind Spo
tAssist is onl yanaid.Itm ayfailto
detect som evehicles and is no substitute for
attentive driving. G
WARNING
Blind Spo tAssist does not react to:
R vehicles overtake ntoo closel yonthe side,
placing them in the blind spo tarea
R vehicles which approach with alarge speed
differential and overtake your vehicle
As aresult, Blind Spo tAssist ma ynot give
warning sinsuchs ituations. There is ariskof
an accident.
