Operation Manual

adaptive cruise control (ACC)140
Setting the driving program
In the Driving program menu you can select either dynamic,
standard or comfort according to your personal preferences.
Note
• We recommend you to leave the warning tone switched on. Even
when the warning tone is switched off, not every warning tone will
be deactivated.
• When you pass the key on to somebody else please remember to
make the other driver aware of the ACC settings.
• We recommend a minimum distance setting of DISTANCE 3
(factory default setting).
• When the ignition is switched off, the distance setting reverts to
the factory default DISTANCE 3. A qualified workshop can cancel
this function. In this case a default distance setting defined on the
sound system or MMI* is applied each time the engine is started.
System limitations
Applies to vehicles: with adaptive cruise control
General notes
The following situations could impair the function of the
radar sensor.
The adaptive cruise control is subject to given physical limits and
also has certain limits determined by the system itself. Under
certain circumstances the driver may feel that the ACC system is
responding unexpectedly or belatedly. For this reason, please
always give your full attention to road traffic and if necessary take
action yourself:
• When driving through bends ⇒ page 140.
• When vehicles in front are not in line with your vehicle
⇒ page 141.
• When other vehicles change lanes ⇒ page 141.
• When other vehicles are not clearly discernible ⇒ page 141
• When vehicles are stationary ⇒ page 142.
WARNING
The radar sensor's "field of vision" can be impaired by rain, snow
or a lot of water on the road. This results in vehicles in front not
being properly recognised or, in some circumstances, not being
detected at all. If necessary, take action yourself!
