the selected distance of its own accord. In some
circumstances, it may also not be possible to re‐
store the selected distance if you are driving sig‐
nificantly faster than vehicles in front, for example
when rapidly approaching a lorry. If a vehicle is
clearly detected in front of you, the system
prompts you to intervene by braking, and if nec‐
essary by taking evasive action.
Cornering
If the desired speed is too high for cornering, it
will be reduced slightly in the bend. However, the
system does not detect bends in advance. For
this reason, moderate your speed when corner‐
ing.
The system has a limited detection range. Situa‐
tions can arise on tight bends where a vehicle
driving in front will not be detected or will be de‐
tected very late.
When your vehicle is approaching a bend, the
angle of the bend may cause the system to re‐
spond temporarily to vehicles in the other lane. If
the system responds by decelerating the vehicle,
you may compensate for this by accelerating
briefly. When the accelerator pedal is released
again, the system will resume control of the vehi‐
cle's speed.
Driving off
The vehicle cannot drive off automatically in
some situations, for example:
▷
On steep upward gradients.
▷
Before bumps or rises in the road.
In such cases, depress the accelerator pedal.
Weather
The following restrictions may apply if the
weather or lighting conditions are unfavourable:
▷
Impaired detection of vehicles.
▷
Brief interruptions when vehicles have already
been detected.
Examples of unfavourable weather or lighting
conditions:
▷
Wet roads.
▷
Snowfall.
▷
Slush.
▷
Fog.
▷
Oncoming light.
Pay attention when driving and respond to the
prevailing traffic conditions. If necessary, inter‐
vene actively, for example by braking, steering or
manoeuvring.
Engine power
The desired speed is also maintained on a down‐
hill stretch. The vehicle may drive slower than the
desired speed on uphill gradients if the engine
power is not sufficient.
In ECO PRO drive mode, it is possible that the
vehicle will intentionally drive faster or slower
than the desired speed setting in some situa‐
tions, for example on downward or upward gradi‐
ents.
