signa l) is turned off.
The text message ... (three white dots) appears if a setting cannot be
implemented with the operat ing lever. The fol lowing are possible
reasons
• If you pu ll the control lever forward to resume speed but no
requested speed was set.
• I f you push the lever up to increase (or down to reduce) speed
when no speed has been set previously.

ment
A CC not a vailab le
The text message ACC not av ailabl e appears, for example, if the
temperature of the brakes is excessive . Adaptive Cruise Control is
t emporarily not availab le . A warning tone sounds as a rem inder.
A CC not available !
The text message ACC not av ailabl e! appears in the event of a
malfunction. Adaptive Cruise Control is turned off . A warning tone
sounds as a reminder. Have the system inspected by a qua lified
dea lersh ip.
ACC senso r blocked
The text message AC C s en so r blo cked appears when the ACC
System does not detect any objects over an extended time period .
For the time being, the distance to vehicles up ahead is not being
cont rolled . The ACC system is not switched off, so increased alert ­
ness is required. The following may be reasons for the text message
ACC sensor blocked:
• The ACC sensor is dirty. The ACC system is not react ing, or is not
reacting correctly, to vehic les traveling ahead.
• It is possible that you are driving on a road with very light traffic
without any thing at the side of the road (e.g. guard rai ls, traffic
s igns, trees). As soon as a vehicle is detected by the system again,
it returns to its control range and the text message d isappears .
The ACC sensor is located in the area under the front license plate .
I f there is a loss of operation due to heavy contamination, this area
should cleaned to restore proper operation.
AC C senso r bl ock ed!
The text message ACC sensor blocked! appears when the ACC
System can no longer guarantee safe detection of objects . Adaptive
cruise control is turned off . A chime sounds as a reminder.
To decide whether it is necessary to switch off t he ACC (ACC sensor
blocked!) or if it is only a temporary condition (ACC sensor blocked),
the system wi ll a lso takes into cons ideration the outside tempera -
ture and/or the windshield wiper operation .
