Speed warning
Principle
The speed warning can be used to set a speed
limit. A warning will be issued when this speed
limit is exceeded.
Speed Limit Info
General information
Another warning occurs when the set speed
limit is exceeded again after it has dropped by
3 mph/5 km/h.
Speed Limit Info

Speed Limit Info shows the currently valid
speed limit in the instrument cluster and, if
necessary, the Head-up display.

Current speed limit.
Without map data, the system is subject to
certain technical limitations. Traffic signs with
speed limitations are detected and displayed
only. Speed limits due to entering towns/cities,
highway signs, etc., are not displayed. Speed
limits with extra traffic signs are always dis-
played.
Depending on the national-
market version, it is possible
to switch between the units of
measurement.
No data on current speed limit
available.

Safety information
Warning signals
Depending on the settings, an acoustic signal
sounds if the detected speed limit is exceeded
or the speed limit changes. The display also
flashes if the detected speed limit is exceeded.
Warning
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, or property damage. Adjust driv-
ing style to traffic conditions. Watch the sur-
rounding traffic situation closely, be ready to
take over steering and braking at any time,
and actively intervene where appropriate.
Settings
Individual settings can be configured for Speed
Limit Info, e.g., warnings issued if the speed is
exceeded or the permissible maximum speed
changes.

There is a risk of accident, injury, or property
damage. Only use the system if driving at
constant speed is possible.
Principle
With the Cruise Control, a set speed can be ad-
justed using the buttons on the steering wheel.
The system maintains the set speed. The sys-
tem accelerates and brakes automatically as
needed.
Warning
The set speed can be incorrectly adjusted or
called up by mistake. There is a risk of acci-
dent, injury, or property damage. Adjust the
set speed to the traffic conditions. Watch sur-
rounding traffic closely and actively intervene
where appropriate
General information

Distance Control
Principle
Using the Cruise Control, a desired speed and
a distance to a vehicle ahead can be adjusted
using the buttons on the steering wheel.
Warning
An unsecured vehicle can begin to move and
possibly roll away. There is a risk of accident,
injury, or property damage. Before leaving
the vehicle, secure the vehicle against rolling
away.
General information
The system maintains the set speed on clear
roads. The vehicle accelerates or brakes auto-
matically.
In order to ensure that the vehicle is secured
against rolling away, follow the following:
If a vehicle is driving ahead of you, the system
adjusts the speed of the vehicle so that the set
distance to the vehicle ahead is maintained.
The speed is adjusted as far as the given sit-
uation allows.

Set the parking brake.
On uphill grades or on downhill slopes,
turn the front wheels in the direction of
the curb.
â–·
On uphill grades or on downhill slopes,
also secure the vehicle, for instance with
a wheel chock.
The distance can be adjusted at several levels.
For safety reasons, it depends on the respec-
tive speed.
If the vehicle ahead of you brakes to a stand-
still and then drives off again within a brief pe-
riod, the system is able to detect this within the
given system limits.

System limits
If a vehicle driving ahead of you suddenly
merges into your lane, the system may not be
able to automatically restore the selected dis-
tance. It may not be possible to restore the se-
lected distance in certain situations, including if
you are driving significantly faster than vehicles
driving ahead of you, for instance when rapidly
approaching a truck. When a vehicle driving
ahead of you is reliably detected, the system
requests that the driver intervene by braking
and making an evasive maneuver, if needed.
System limits of the sensors
Additional information:
â–·
â–·
Cameras, refer to page 37.
Radar sensors, refer to page 38.
Detection range
The detection capability of the system and the
automatic braking performance are limited.
For instance, two-wheeled vehicles may not be
detected.
210
Driver assistance systems

Cornering
Weather
The following restrictions can occur under un-
favorable weather or light conditions:
â–·
â–·
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:
â–·
â–·
â–·
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.
