i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
Important safety notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. Change into
al ower gear in good time on long and steep
downhill gradients. Take particular noteof
this when driving aladen vehicle. By doing so,
you will make use of the braking effect of the engine. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly. If you need
additional braking, depress the brake pedal
repeatedly rather than continuously.
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an
accident nor override the laws of physics.
SPEEDTRONIC cannot take into account
road, weather or traffic conditions. SPEED-
TRONIC is only an aid. You are responsible for
the distance to the vehicle in front,f or vehicle
speed, for braking in good time, and for stay- ing in lane.
If there is achange of drivers, advise the new
driver of the speed stored.
You can set avariable or permanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when driving with winter tyres
fitted i
The speed indicated in the speedometer
may differ slightly from the limit speed

R other vehicles changin glane
R narrow vehicles
R obstructions and stationary vehicles

At speedsofm ore than 60 km/h ,Steering

(left and right), only focusing on the vehicle in
front if detected lane markings are not pres-
ent.
If these conditions are not present, Steering

Important safety notes
If you fail to adapt yourd riving style,

DISTRONIC PLUS with Steering Assist and
Stop&Go Pilotd oes not detect road and traf-
fic conditions and does not detect all road
users. If you are following avehicle which is
driving towards the edge of the carriageway,
yourv ehicle could come into contact with the
kerb or other road boundaries. Be particularly
aware of other road users, e.g. cyclists, that
are directly next to yourv ehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g.
after intentionally driving over alane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilotc annot continuousl ykeep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehi-
cle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it
does not leave the lane.
The support offered by the system may be
impaired if:
R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R the windscree nisdirty, misted up, dam-
aged or covered, for instance by asticker,

R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highlyv ariable shade conditions
