If all activation conditions are met, you can acti‐
va te Dis tance Pilot DISTRONIC du ring a jou rney
or while stationar y.When Dis tance Pilot
DISTRONIC is acti vated, a speed is stored which
th e driver can increase or reduce at any time.
The speed can be adjus ted between 20 km/h
and 200 km/h.
Ve hicles with the Driving Assistance Pack‐
age: The speed can be adju sted between
20 km/h and 210 km/h.
Ve hicles with Driving Assistance Package,
Pa rking Pilot and COMAND Online: Upto30
seconds af terst opping, theve hicle automatically
fo llo ws theve hicle ahead without the inter ven‐
tion of the driver. This is only possible if theve hi‐
cle is tr avelling on a mo torw ay or a high-speed
major road. If an obs tacle is de tected in front of
th eve hicle during the driving-off procedure, a
ta ke ove rwa rning is given. Acceleration is
re duced, the driver is given a visual and acoustic
wa rning and must stop theve hicle before reach‐
ing the obs tacle or take evasive action. Ve

Even if theve hicle in front lea vesth e de tection

DISTRONIC temp orarily maintains the cur rent

If yo u activate the turn signal indicator tochange
lanes, theve hicle will accelerate more briskly to
th e set speed under thefo llowing conditions:
R Distance Pilot DISTRONIC is acti vated.
R Ifth e driving speed is higher than 70 km/h. R
Ifth e driven speed drops below thestored

R Ifth e tra ffic situation in theove rtaking lane
permits a safe lane change.

DI STRO NIC also has the Speed Limit Pilot func‐
tion. This function can be confi gured inthe mul‐
timedia sy stem. If a change in the speed limit is
de tected and Dis tance Pil otDISTRONIC is acti va‐
te d, Dis tance Pilot DISTRONIC assumes this new
speed.
The driven speed is adap ted when theve hicle is

indicating entry into an urban area, the speed is
adap ted beforehand. The speed limit display in

St eering Pilot sy stem limits
St eering Pilot has a limited steering torque for
lateral guidance. In some cases, thesteering
inter vention is not su fficient tokeep theve hicle
in the lane.
If de tection of lane markings and vehicles ahead
is impaired, Steering Pilot switches topassive
mode. The sy stem pr ovides no support in this
case. During the transition from the active to
passive status theè symbol is shown as
enlar ged and flashes yello w. Once the sy stem is
passive theè symbol is gr eyed out in the
multifunction displa y.
The sy stem may be impaired or may not function
in thefo llowing situations:
R Ifth ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, or due tosno w,
ra in, fog or spr ay.
R Ifth ere is glare, e.g. from oncoming traf fic,

R If no, or se veral, unclear lane markings are
present for one lane, e.g. in a construction
area.
R Ifth e lane markings are wornaw ay, dark or
