tsafety notes G
WARNING
Active Blind Spo tAssist is only an aid and may
detect vehicles/obstacles incorrectly or not
at all.
The system ma ybeimpaired or may not func-
tio nif:
R there is po orvisibility ,e.g. due to snow,
rain, fog or spray.
R the rear and/or front sensors are dirty.
Active Blind Spot Assist may not detect nar-
row vehi cles, such as motorcycles or bicycles,
or only detect the mtoo late. It can notd etect
vehicles which are overtaken at asmall dis-
tance and then enter th eblind spot area.
Active Blind Spot Assist cannot detect road

Active Blin dSpot Assist monitors cer tain
areas in the immediate vicinit yofyour vehicle.
Vehicles that approach and driv epast at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correc tyour course.
If the lanes are ver ywide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are drivin ginastaggered formation.
