Collision Warning - Mercedes-Benz Vito 111 CDI/BlueTEC Operating Instructions Manual

Monitoring range of the sensors
Blind Spot Assist monitors the area up to 3 m
behind your vehicle and directly next to your
vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane.
Due to the nature of the system:
warnings may be issued in error when driving
R
close to crash barriers or similar solid lane
borders
warnings may be interrupted when driving
R
alongside long vehicles, for example lorries,
for a prolonged time
The two sensors for Blind Spot Assist are inte-
grated into the sides of the rear bumper. Make
sure that the bumper is free of dirt, ice or slush
in the vicinity of the sensors. The radar sensors
must not be covered, for example by rear-moun-
ted cycle racks or overhanging loads. Following
a severe impact or in the event of damage to the
bumper, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may otherwise not work prop-
erly.
Warning display
Blind Spot Assist is not active at speeds below
approximately 30 km/h. Vehicles in the moni-
toring range are then not indicated.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
approximately 30 km/h, warning lamp : lights
up red on the corresponding side. Warning
lamp : always lights up when a vehicle enters
the blind spot monitoring range from behind or
from the side. When you overtake a vehicle, the
warning only occurs if the difference in speed is
less than 11 km/h.
If you select reverse gear, Blind Spot Assist is
inactive.
The intensity of warning lamps : depends on
the brightness of the ambient light and is con-
trolled automatically.
