When the warning function is active and you pass
a traffic sign, the instrument cluster shows the
traffic regulations (speed limit and overtaking
restriction) for five seconds. The previous menu
then reappears automatically.
The wrong-way warning remains active if you
deactivate the warning function of Traffic Sign
Assist.
Blind Spot Assist
Function of Blind Spot Assist
Blind Spot Assist uses two lateral, rear-facing
radar sensors to monitor the area directly next to
and on the side behind the vehicle.
& WARNING Risk of accident despite Blind
Spot Assist
Blind Spot Assist does not react to either sta‐
tionary objects or vehicles approaching and
overtaking you at a greatly different speed.
Blind Spot Assist cannot warn drivers in these
situations.
Always pay careful attention to the traf‐
#
fic situation and maintain a safe dis‐
tance at the side of the vehicle.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nise dangers ( page 155).
/
If a vehicle is detected above speeds of approx‐
imately 12 km/h and this vehicle subsequently
enters the monitoring range directly next to your
vehicle, the warning lamp in the outside mirror
lights up red.
If a vehicle is detected close to your vehicle in the
lateral monitoring range and you switch on the
turn signal indicator in the corresponding direc‐
tion, a warning tone sounds. The red warning
lamp in the outside mirror flashes. If the turn sig‐
nal indicator remains switched on, all other
detected vehicles are indicated only by the flash‐
ing of the red warning lamp.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
approximately 20 km/h.
