Target speed
The target speed set by the driver is indicated by a red diode in the
speedometer.
If the speed setting is between two graduations on the speedom-
eter dial, the two closest diodes will both light up ⇒ fig. 143.
It is only possible to set target speeds ranging from 30 to 200 km/h.
This speed range is illuminated slightly by the diodes on the speed-
ometer dial.
Indicator lamp (symbol)
• No vehicle in front: The green indicator lamp ⇒ page 134,
fig. 144 shows that the adaptive cruise control system is in cruise
mode and that there is no vehicle in front. It maintains the stored
target speed.
• Vehicle in front: The green indicator lamp shows that the
system has detected a vehicle in front. The speed is adapted to the
vehicle in front. The adaptive cruise control system accelerates and
brakes the vehicle automatically.
• Driver intervention prompt: When the red indicator lamp
flashes , this is a warning for the driver to intervene. The driver
has to brake the vehicle with the foot brake. This warning lamp will
always appear when the adaptive cruise control system alone is not
able to brake the vehicle sufficiently to maintain a safe distance to
a vehicle in front. An audible alarm (warning tone) will also sound
when the lamp starts to flash. For further information on the driver
intervention prompt ⇒ page 138.
Note
• If you exceed the target speed by using the accelerator, the
driver intervention prompt will not be accompanied by a warning
tone. The indicator lamp shown in the speedometer will also switch
off if the target speed is exceeded.
• You can change the volume of the warning tone on the sound
system or MMI* ⇒ page 139, “Setting the warning tone volume and
driving program”.
