lowing:
R Driving with particular care
R Driving theve hicle in drive program ;
R Observing thege arshift recommendations The inner segment will light up and
the outer
segment will fill up when thefo llowing driving
st yle is adop ted:
R 1 Moderate acceleration
R 2 Gentle deceleration and rolling
R 3 Consis tent speed
The inner segment will not light up and the outer
segment will em pty when thefo llowing driving
st yle is adop ted:
R 1 Sporty acceleration
R 2 Heavy braking
R 3 Fluctuations in speed
The ECO display will show you when you ha ve
driven economically:
R The thre e outer segments are comple tely fil‐

R The speed is within a suitable range.
R The road's course is suitable, e.g. no steep
uphill or downhill inclines or tight bends.
R There is no trailer hitched up tothe trailer

Sy stem limits
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, you will make use of the engine's brak‐
ing ef fect. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐

Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads. R
On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for a short-term speed restriction,
e.g. in built-up areas
R Perm anen t:for a longer-term speed restric‐
tion, e.g. in winter tyre mode
Yo u can store any speed abo ve20 km/h up to

If speed limit change between 20 km/h and
13 0 km/h is de tected and the automatic adop‐
tion of speed limits is active, it will be automati‐
cally adop ted as thestored speed
(/ page 212).
The driven speed is adju sted when theve hicle is
le ve l with the traf fic sign at the latest. In the
case of signs indicating entry into an urban area,
th e speed is adap ted according tothe speed
permitted within the urban area. The speed limit display in
the Instrument Display is alw ays upda‐
te d when theve hicle is le vel with the tra ffic sign.
If th ere is no speed restriction on an unlimited
st re tch of road (e.g. on a mo torw ay),th ere com‐
mended speed is auto maticallyadop ted as the
st ored speed. The sy stem uses the speed stored
on an unlimited stre tch of road as there com‐
mended speed. If you do not alter thestored
speed on an unlimited stre tch of road, there c‐
ommended speed is 130 km/h.
If Ac tive Dis tance Assi stDISTRONIC has been
