Driver assistance systems
CONTROLS
Cornering
Weather
The following restrictions can occur under un-
favorable weather or light conditions:
▷
▷
Poorer vehicle detection.
Short-term interruptions for vehicles that
are already recognized.
Drive attentively, and react to the current sur-
rounding traffic situation. If necessary, inter-
vene actively, for instance by braking, steering
or making an evasive maneuver.
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.
Drive power
The set speed is also maintained downhill. The
speed may not be maintained on uphill grades
if the drive power is insufficient.
The system has a limited detection range. Sit-
uations can arise in tight curves where a vehi-
cle driving ahead will not be detected or will be
detected very late.
In ECO PRO driving mode, the vehicle may
exceed 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 ap-
plied.
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 decel-
erates you may compensate for it by briefly
accelerating. After releasing the accelerator
pedal the system is reactivated and controls
speed independently.
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.
Driving off
In some situations, the vehicle cannot drive off
automatically; for example:
Active Cruise Control with Distance Control.
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.
▷
▷
On steep uphill grades.
In front of bumps in the road.
In these cases, step on the accelerator pedal.

The system cannot serve as a substitute for
the driver’s personal judgment in assessing
the traffic situation. Based on the limits of
the system, it cannot independently react to
all traffic situations. There is a risk of acci-
dent, injury, and property damage. Adjust
driving style to traffic conditions. Watch the
surrounding traffic situation closely, be ready
to take over steering and braking at any time,
and actively intervene where appropriate.
▷
"Adjust manually": detected speed limits
can be applied manually.
▷
"Show anticipation": Depending on the
national-market version: current and up-
coming speed limits are displayed in
the instrument cluster without being ap-
plied.
▷
▷
"Show current limit": current speed lim-
its are displayed without being applied
in the instrument cluster.
"Off": depending on the national-market
version, Speed Limit Info and Speed

Warning
The set speed can be incorrectly adjusted or
called up by mistake. There is a risk of acci-
dent, injury, and property damage. Adjust the
set speed to the traffic conditions. Watch sur-
rounding traffic closely and actively intervene
where appropriate
