the time bei ng, the distance to vehicles up
ahead is not being controlled. The ACC system
is not sw itched off, so inc reased alertness is
required. The follow ing may be reasons for
the text message ACC Functiona lly limited:
- The ACC sensor is dirty. The ACC system is
not reacting, or is not react ing correct ly, to
vehicles traveling ahead .
- It is possible that you are driving on a road
with very light traffic without anyt hing at
the side of the road (e.g. guard ra ils, traffic
s igns, trees). As soo n as a vehicle is detected
by the system again, it retu rns to its contro l
range and the text message disappea rs.
The ACC sensor is located in the right front

loss of operation due to heavy co ntamination,
this area should clea ned to restore prope r op-
e rat ion.
