CONTROLS
Cornering
When the set speed is too high for a curve, the
speed is reduced slightly. Because curves may
not be anticipated in advance, drive into a curve
at an appropriate speed.
The system has a limited detection range. Situa‐
tions can arise in tight curves where a vehicle
driving ahead will not be detected or will be de‐
tected very late.
When you approach a curve the system may
briefly report vehicles in the next lane due to the
bend of the curve. If the system decelerates you
may compensate it by briefly accelerating. After
releasing the accelerator pedal the system is re‐
activated and controls speed independently.
Driving off
In some situations, the vehicle cannot drive off
automatically; for example:
▷ On steep uphill grades.
▷ In front of bumps in the road.
In these cases, step on the accelerator pedal.

Weather
The following restrictions can occur under unfav‐
orable weather or light conditions:
▷ Poorer vehicle detection.
▷ Short-term interruptions for vehicles that are
already recognized.
Drive attentively, and react to the current traffic
situation. If necessary, intervene actively, for in‐
stance by braking, steering or evading.
Drive power
The set speed is also maintained downhill. The
speed may not be maintained on uphill grades if
the drive power is insufficient.
In ECO PRO driving mode, the vehicle may ex‐
ceed or drop below the set desired speed in
some situations, for instance on downhill or uphill
grades.
Speed Limit Assistant
Principle
Speed Limit Assistant supports driving at the
speed limit. A suggested speed can be applied.
General information
When the systems in the vehicle, e.g., Speed
Limit Info, detect a change of the speed limit, this
new speed value can be applied for the following
systems:
▷ Manual Speed Limiter.
▷ Cruise control.
▷ Active Cruise Control with Stop&Go function
ACC.
The speed value is suggested as the new de‐
sired speed to be applied. To apply the speed
value, the corresponding system must be acti‐
vated.
