Mercedes-Benz E-Class Estate 2021, Owner'S Manual

Page: 230 / 533

The driven speed is adjusted when the vehicle is
level with the tra c sign at the latest. In the case
of signs indicating entry into an urban area, the
speed is adapted according to the speed permit-
ted within the urban area. The speed limit display
in the Instrument Display is always updated when
the vehicle is level with the tra c sign.
If there is no speed restriction on an unlimited
stretch of road (e.g. on a motorway), the recom-
mended speed is automatically adopted as the
stored speed. The system uses the speed stored
on an unlimited stretch of road as the recommen-
ded speed. If you do not alter the stored speed on
an unlimited stretch of road, the recommended
speed is 130 km/h.
If Active Distance Assist DISTRONIC has been put
into passive mode by pressing the accelerator
pedal, only speed limits which are higher than the
set speed are adopted.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers (

Syst System limits em limits
The system limits of Tra c Sign Assist apply to
the detection of tra c signs (
/
page 238).
Speed limits below 20 km/h are not automatically
adopted by the system as the stored speed. Tem-
porary speed restrictions (e.g. for a certain time
or due to weather conditions) cannot be properly
detected by the system. The maximum permissi-
ble speed applying to a vehicle with a trailer is not
detected by the system.
Adjust the speed in these situations.

W WARNING ARNING Risk of accident due to Active
Speed Limit Assist adapting the vehicle's
speed
The speed adopted by Active Speed Limit
Assist may be too high or incorrect in some
individual cases, such as:
R
at speed limits below 20 km/h
R
in wet conditions or in fog
R
when towing a trailer
#
Ensure that the driven speed complies
with tra c regulations.
#
Adjust the driving speed to suit current
tra c and weather conditions.
FFunction of r unction of rout oute-based speed adapt e-based speed adaptation ation
When Active Distance Assist DISTRONIC is activa-
ted, the vehicle speed will be adapted accordingly
to the route events ahead. Depending on the drive
program selected, the vehicle negotiates a route
event ahead in an economical, comfortable or
dynamic manner. When the route event has been
passed, the vehicle accelerates again to the
stored speed. The set distance to the vehicle in
front, vehicles detected ahead and speed restric-
tions ahead are taken into account.
You can activate and deactivate route-based
speed adaptation in the multimedia system
(

page 228).
The following route events are taken into account:
R
Bends
R
T-junctions, roundabouts and toll stations
R
Turns and exits
