iUSA only:
This device has been approved by the FCC as
a" Vehicular Rada rSystem". The radar sensor
is intended for use in an automotive radar
system only. Removal, tampering, or altering
of the device will void any warranties, and is
not permitted by the FCC. Do not tamper with,
alter, or use in any non-approved way.
Any unauthorized modification to this device
could void the user’s authority to operate the

Monitoring range of the sensors
Blind Spot Assist monitors the area shown in the
diagramupt o118 in (3 m) behind and directly
next to your vehicle.
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-

case if the vehicles are driving on the inner side
of their lane.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similars olid lane
borders.
Rwarnings may be interrupted when driving
alongside long vehicles, for example trucks,
for aprolonged 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
as evere impact or in the event of damage to the
bumper, have the function of the radar sensors
checked at aqualified specialist workshop.
Blind Spot Assist may otherwise not work prop-
erly.
Warning display
Blind Spot Assist is not active at speeds below
