DI ST RO 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 Pilot DISTRONIC is acti va‐
te d, Dis tance Pilot DISTRONIC assumes this new
speed. The driven speed is adap
ted when theve hicle is
le ve l with the tra ffic signs. The speed limit dis‐
play in the Instrument Display is alw ays update d
when theve hicle is le vel with the tra ffic sign.
If th e Dis tance Pilot DISTRONIC has been put
into passive modebypressing the accelerator
pedal, only speed limits which are higher than
th e se t speed are adop

pla yed speed limit as the speed, pr ovided that:
RThe Speed Limit Pilot has been activated in
the multimedia sy stem and
RDis tance Pilot DISTRONIC has been acti va‐

If no speed limit is displa yed when the le ver is
operated, the speed set bythe driver is adop ted.

RSteering Pilot can be overridden at any time
by steering theve hicle yourself.
RIfth e sy stem de tects that there are no lane

Sy stem limitations of Steering Pilot
St eering Pilot has a limited steering torque for
lateral guidance. In some cases, thesteering
inter vention is not suff icienttokeep 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 shown as gr ayinthe

Fu nction of Active Lane Change Assi st
St eering Pilot is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay ‐
ing in lane. Before changing lanes, make sure
th at the neighboring lane is free (shoulder view). %
The availability of thefo llowing function is
countr y-dependent.
St eering Pilot remains active even if the turn sig‐
nal indicator is switched on. Steering Pilot then
assists the driver when changing lanes byapply‐
ing steering torques toinitiate the lane change.
Assis tance when changing lanes is pr ovided if all
th efo llowing conditions are me t:
RYou are driving on a free wayor high-speed
multi-lan emajo rro ad with multiple lanes in
th e direction of tr avel.
RThe neighboring lane is free and separated
bya broken lane marking.
RThe driven speed is between 50 mph
(80 km/h) and 110mp h(1 80 km/h).
RThe turn signal indicator is switched on for
longer than two seconds.
