ECO Assist can function even more precisely if
th ero ute is adhered towhen route guidance is
active. The basic function is also available without
active route guidance. Not all information and
tra1c situations can be fore seen. The quality
depends on the map data.
ECO Assist is only an aid. The driver is responsible
fo rke eping a safe distance from theve hicle in
front, forve hicle speed and for braking in good
time. The driver must be ready tobrake at all
times ir respecti veof whe ther the system inter-
ve nes.
The system may be impai red or may not function
in thefo llowing situations:
R If visibility is poor, e.g. due toinsu1cient illu-
mination of thero ad, highly variable shade
conditions, rain, sno w,fog or heavy spr ay.
R Ifth ere is glare, e.g. from oncoming tra1c,
direct sunlight or re0ections.
R Ifth ere is dirt on the windscreen in the area of
th e multifunction camera or the camera is
misted up, damaged or obscured. R
Ifro ad signs are hard todetect, e.g. due to
dirt, snow or insu1cient lighting, or because
th ey are obscured.
R Ifth e information on the navigation system's
digital map is incor rect, insu1cient or out of
date.

The route-based operating-mode strategy is active

of thero ute is evaluated. This includes, e.g. road
type, speed limi tations and altitude data. The
hybrid system then adapts the operating

If a change in the speed limit of 20 km/h or more
is de tected and automatic adoption of speed lim-
its is activated, the new speed limit is automati-
cally adop ted as the stored speed (/ page 252).
The driven speed is adjusted when theve hicle is
le ve l with the tra1c sign at the latest. In the case
of signs indicating entry into an urban area, the
speed is adap ted according tothe speed permit-
te d within the urban area. The speed limit display in
the Instrument Display is alw ays updated when
th eve hicle is le vel with the tra1c sign.
If th ere is no speed restriction on an unlimited
str etch ofroad (e.g. on a mo torw ay),th ere com-
mended speed is automatical lyadop ted as the
stored speed. The system uses the speed stored
on an unlimited str etch ofroad as there commen-
ded speed. If you do not alter the stored speed on
an unlimited str etch ofroad, there commended
speed is 130 km/h.
If Ac tive Distance Assist DISTRONIC has been put
into passive mode bypressing the accelerator
pedal, only speed limits which are higher than the
set speed are adop ted.

individual cases, such as:
R at speed limits below 20 km/h

When Active Distance Assist DISTRONIC is acti va-
te d, theve hicle speed will be adap ted accordingly
to thero ute events ahead. Depending on the drive prog
ram selected, theve hicle neg otiates a route
ev ent ahead in an economical, comfor table or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
stored speed. The set distance totheve hicle in
front, vehicles de tected ahead and speed restric-
tions ahead are take n into account.
Yo u can activate and deactivate route-based
speed adap tation in the multimedia system
(/ page 241).
The following route events are take n into account:
R Bends
R T-junctions, roundabouts and toll stations
R Turns and exits
R Tra1c jams ahead (only with Live Tra1c Infor-
mation )
% When theto ll station is reached, Active Dis-
ta nce Assist DISTRONIC ado ptsth e speed as
th e stored speed.
Also, the speed is reduced if the turn signal indi-
cator tochange lanes is switched on and one of
th efo llowing situations is de tected:
R Turning o. at junctions R
Driving on slowing-down lanes
R Driving on lanes adjacent toslowing-down
lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tojunctions, roundabouts and
tra1c lights, as route-based speed adap tation
does not brake theve hicle toa standstill.
When route guidance is active, the /rst speed
