The driver is responsible forke eping a safe dis‐
ta nce totheve hicle in front, forve hicle speed
and for braking in good time.
Sy stem limitations
The sy stem may be impaired or may not function
in thefo llowing ins tances, forex ample:
RIn snow ,ra in, fog, heavy spr ay, if there is
gl are, in direct sunlight or in greatly varying
ambient light.
RThe windshield in the area of the camera is
dirty, fogged up, damaged or co vered.
RIfth era dar sensors are dirty or co vered.
ROn slippery roads, braking or accelerating
can cause the drive wheels tolose traction
and theve hicle could then skid.

uphill or downhill gradients.
Do not use Active Dis tance Assist DISTRONIC in
th ese situations.

RIfth eve hicle pulls away using Active Dis‐
ta nce Assist DISTRONIC.
RIfth estored speed is called up and is
considerably faster or slo werth an the

If th ere is no speed restriction on an unlimi ted
st re tch of road (e.g. on a highwa y),there com‐
mended speed is adop ted as thestored speed.
The sy stem uses the speed stored on an unlimi‐

If yo udo not alter thestored speed on an unlimi‐
te dstre tch of road, there commended speed is
80 mph (130 km/h).
If Ac tive Dis tance Assist DISTRONIC has been
put into passive modebypressing the accelera‐
to r pedal, only speed limits which are higher
th an the set speed are adop ted.
Ac tive Speed Limit Assi stcan be configu red in
th e multimedia sy stem (
→page 195).
Ac tive Speed Limit Assi stis only an aid. The
driver is responsible forke eping a safe dis tance
to theve hicle in front, forve hicle speed and for
braking in good time. The maximum permissible
speed also depends on factors such asthero ad
sur face and traf fic conditions. Sy
stem limitations
Te mp orary speed restrictions (e.g. for a cer tain
time or due towe ather conditions) cannot be
proper lyde tected bythe sy stem. The maximum
permissible speed applying for a vehicle with a
trailer is not de tected bythe sy stem. In these sit‐

Function of route-based speed adaptation
%
The availability of thefo llowing function is
countr y-dependent.
When Dis tance Assist DISTRONIC is acti ve,th e
function adju ststh e speed depending on the
ro ute events ahead. Depending on the drive pro‐
gram selected, theve hicle negotiates thero ute
eve nt ahead in a fuel-s aving, com fortable or
dynamic manner. When thero ute event has been
passed, theve hicle accelerates again tothe
st ored speed. The set dis tance totheve hicle
ahead, vehicles de tected ahead and speed
re strictions ahead are take n into account.
Ro ute-based speed adjustment can byconfig‐
ured in the multimedia sy stem (
→page 167).
Ro ute events ahead are:
RBends
RT-intersection, traf fic circles and tollst ations
RTu rns and exits
% When theto llst ation is reached, Active Dis‐
ta nce Assist DISTRONIC adopts the speed as
th estored speed.

Also,the speed is reduced if the turn signal to
ch ange lanes is switch ed on and one ofthefo l‐
lowing situations is de tected:
RTu rning off at intersections
ROn slowing-down lanes
ROn lanes adjacent toslowing-down lanes
The driver is responsible forch oosing theright
speed and observing other road users. This
applies in particular tointersections, traf fic cir‐
cles and sets of traf fic lights, as route-based
speed adap tation does not brake theve hicle toa

Speed adjustment is canceled in thefo llowing
cases:
RIf th e turn signal indicator is switched off
before thero ute event.
RIfth e driver depresses the accelera tor or
brake pedal during the process. Sy
stem limitations
Ro ute-based speed adaptation does not take
ri ght of wayre gulations into account. The driver
is responsible for complying with road traf fic
re gulations and driving at a suitable speed.
In dif ficult conditions (e.g. unclear roads, nar row
lanes, wetro ad sur faces, snow or ice) or when
driving wi tha trailer, the speed adjustment made
by the sy stem may not alw
ays be suitable. In
th ese sit

System limitations
Ac tive Steering Assist has a limited steering tor‐
qu efo r lateral guidance. In some cases, the
st eering inter vention is not suff icienttokeep the
ve hicle in the lane or todrive past exits. Active
St eering Assist cann otprov ide the driver with
st eering assis tance at traf fic circles, T-intersec‐
tions, intersections, tollst ations or turns, for
ex ample.
The sy stem may be impaired or may not function
