Cornering
If the desired speed is too high for corner-
ing, it will be reduced slightly in the corner.
However, the system does not detect cor-
ners in advance. For this reason, moderate
your speed when cornering.
The system has a limited detection range.
Situations can arise on tight bends where a
vehicle driving in front will not be detected
or will be detected very late.
When your vehicle is approaching a bend,
the angle of the bend may cause the system
to respond temporarily to vehicles in the
other lane. A possible reduction in the vehi-
cle's speed by the system can be compensa-
ted for by briefly accelerating. When the ac-
celerator pedal is released again, the system
will resume control of the vehicle's speed.
Weather
The following restrictions may apply if the
weather or lighting conditions are unfav-
ourable:
– Impaired detection of vehicles.
– Brief interruptions when vehicles have
already been detected.
Examples of unfavourable weather or light-
ing conditions:
– Wet roads.
– Snowfall.
– Slush.
– Fog.
– Oncoming light.
Pay attention when driving and respond to
the prevailing traffic conditions. If neces-
sary, intervene actively, for example by
braking, steering or manoeuvring.
Engine power
The vehicle may drive slower than the de-
sired speed on gradients, if the engine
power is not sufficient.
Malfunction
A Check Control message is displayed if the
system has failed or has been automatically
deactivated.
The system may have limited functionality
in the following situations, for example:
– If an object has not been correctly de-
tected.
– In thick fog, wet conditions or snow.
– On sharp bends.
– If the field of view of the camera or the
windscreen is dirty or covered.
– With bright oncoming light.
– Up to 20 seconds after starting the en-
gine using the start/stop button.
– During the camera calibration process
immediately after vehicle delivery.
