WARNING Risk of accident due tounex‐
pecte d acceleration byDis tance Pilot
DISTRONIC
If Dis tance Pilot DISTRONIC no longer
de tects a vehicle in front, it may unexpect‐
edly accelerate tothe speed stored.
RThis speed may be too high for a turning
lane or an exit lane.
RIf driving in theright lane, this speed may
be so high that you pass vehicles driving
on the left (in count ries where tra ffic
drives on theright).
RIf driving in the left lane, this speed may
be so high that you pass vehicles driving
on theright (in countri es where traffic
drives on the left).
Alw ays carefully obser vethe tra ffic condi‐
tions and be ready tobrake at all times.
&
WARNING Risk of accident due toDis‐
ta nce Pilot DISTRONIC pulling away auto‐
matically
If Dis tance Pilot DISTRONIC pe rforms an
automatic driving-off procedure, theve hicle
may accelerate unexpectedl y.
Where necessar y,brake theve hicle yourself
and take evasive action.

WARNING Risk of accident due toSpeed
Limit Pilot adapting theve hicle's speed
The speed adop tedby the Speed Limit Pilot
may be too high or incor rect in some individ‐
ual cases, such as:
RInthewe t or in fog
RWhen towing a trailer
Ensure that the driven speed complies with
traf fic re gulations.
Re quirementsRThe vehicle's engine or must be switched on.
RThe electric parking brake must be released.
RPa rking Pilot is not being used topark the
ve hicle or toexit from a parking space.
RESP®must be switched on, but not inter ven‐
ing.
RThe transmission must be in positionD.
RThe driver door, front passenger door and the

Driving and pa rking

RIfth e sy stem de tects that there are no lane
markings, it uses theve hicle ahead as a ref‐
erence up toa speed of 80 mph(1 30 km/h).
RWhen the sy stem is actively steering, the
è symbol is shown in green in the multi‐
function displa y.
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 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 gr ayed out in the
multifunction displa y.
The sy stem may be impaired or may not function
in thefo llowing situations:
RIf th ere is poor visibility, e.g. due toinsuf fi‐
cient illumination of thero ad, or due tosno w,
ra in, fog or spr ay.
RIfth ere is glare, e.g. from oncoming traf fic,
dire ct sunlight or reflection from other vehi‐
cles (e.g. if thero ad sur face is wet).
RIfth e windshield is dirty, fogged up, damaged
or co vered, for ins tance byast icke r,in the
vicinity of the camer a.
RIf no, or se
veral, unclear lane markings are
present for one lane, e.g. in a construction
area.
RIf th e lane markings are wornaw ay, dark or
co vered up, e.g. bydirt or sno w.
RIfth e dis tance totheve hicle in front is too
small and the lane markings thus cannot be
de tected.
RIfth e lane markings change quickl y,e.g.
lanes branch off, cross one ano ther or
mer ge.
RIfth ero ad is nar rowand winding.
RIfth ere are highly variable shade conditions
on thero ad.
RIfth ere are obs tacles such as traffic guid‐
ance posts on the lane or projecting out into
th e lane. The sy
stem does not pr ovide assis tance in the
fo llowing conditions:
ROn very sharp bends.
RWhen towing a trailer.
RIfyo u actively change lane without switch ing
on the turn signal indicator.
RIfyo uswit chon the turn signal indicator and

Note s onSteering Pilot
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 your lane. Before changing lanes, make
sure that the neighboring lane is free (shoulder
view).

% The availability of thefo llowing function is

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 torque toinitiate the lane change.

WARNING Risk of accident when trans‐
porting vehicles with AIR BODY CON‐
TROL
The reduced damping forc es on theve hicle
being transpor ted can cause theve hicle/
trailer combination tostart toswing.
As a result, when transporting vehicles with
AIR BODY CONTROL theve hicle/trailer com‐
bination may start toskid. Consequentl y,yo u
could lose control of your vehicle.
There is a risk of accident and injur y.
