vehicle to a standstill,  the adapt.ive cruise contr o l 
will not be switched off automatically wh en  the

matically and  the adap tive cruise control will be 
switched off  if one of the following situations  occurs 
while the vehicle is stationary:

vehicles with automatic gearbox) 
After a stationary  phase, the  adaptive  cruise con
trol can start the vehicle  moving automatically as 
soon as the vehicle  in front  begins  to move again.

taking manoeuvre , the  adaptive  cruise control ac
celerates the  vehicle automatically and  thus re
duces the  distance to the  vehicle  in front.

automatically increase  the speed  to your set level 
and maintain  it.
