Speed Limit Info
Speed warning
Speed Limit Info
Principle
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 uses a camera near the in-
terior rearview mirror to detect road signs at
the edge of the road as well as overhead sign
posts.
General information
Another speed warning is given when the set
speed limit is exceeded again after it has drop-
ped by 3 mph/5 km/h.
Speed Limit Info shows the currently valid
speed limit in the instrument cluster and, if
necessary, the Head-up display.
Speed Limit Info may also show speed limits
that apply to routes that are not signposted if
the navigation system has current map data.
Activating/deactivating the speed
warning
To activate/deactivate the Speed Warning,
go through the menu as follows: Apps
menu / "Vehicle" / "Driving settings" / "Driver
Assistance" / "Safety and warnings" / "Speed
warning".
General information
Traffic signs with subplates are analyzed and
compared with the vehicle's on-board data.
The traffic sign will then be either displayed
or ignored depending on the situation in the
instrument cluster and the Head-up display.
Adjusting the speed
For Speed Limit Info to function correctly, cur-
rent map data for the country in which the ve-
hicle is operated must be downloaded.
1. To set the speed, go through the menu
as follows: Apps menu / "All" / "Driving
settings" / "Driver Assistance" / "Safety and
warnings" / "Speed warning".
For information on the current map version
and the driver assistance map, see “Driver as-
sistance map” under “Navigation system”.
2. Select the desired setting.
Without map data, the system is subject to
certain technical limitations. Traffic signs with
speed limitations are detected and displayed

Warning
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.
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.

exceeded or the permissible maximum speed
changes.

Speed control systems
Principle
The speed control systems provide assistance
while driving, for example, by limiting your
speed, maintaining your distance, or keeping
your vehicle in its lane.
These systems are operated using the buttons
on the steering wheel.

Principle
With the Cruise Control, the buttons on the left
of the steering wheel can be used to adjust
your set speed. The system maintains the set
speed. The system accelerates and brakes au-
tomatically as needed.
On the left side of the steering wheel,
repeatedly press the rocker button up

may not be possible to restore the selected
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 has been
detected ahead of you, the system requests
that the driver intervene by braking and mak-

Weather
Under unfavorable weather or light conditions,
Distance Control may be limited in the follow-
ing ways:
▷
▷
Poorer vehicle detection.
When Distance Control is on, if your set speed
is too high for a bend, your vehicle will be
slowed slightly in the bend. Because curves
may not be anticipated in advance, drive into a
curve at an appropriate speed.
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.
Distance Control has a limited detection range.
Situations can arise in tight curves where a ve-
hicle driving ahead will not be detected or will
be detected very late.
Drive power
Depending on the drive mode or drive power,
the vehicle may exceed or drop below the set
desired speed in some situations, e.g., when
driving uphill or downhill.
Assisted Driving Mode
Principle
Assisted Driving Mode enhances Distance
Control with Steering Assistance and lane
keeping. The system assists the driver in keep-
ing the vehicle within the lane. For this pur-
pose, the system executes supporting steering
movements, for instance when cornering.
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.
Assisted Driving Mode is operated using the
buttons on the steering wheel.
Depending on vehicle speed, Assisted Driving
Mode orients itself using the lane markings or
preceding vehicles.
Driving off
Your vehicle cannot drive off automatically us-
ing Distance Control in the following situations,
for example:
Sensors in the steering wheel detect whether
the steering wheel is being touched.
