with the curb or other road boundaries. Be par-
ticularly aware of other road users, e.g. cyclists,
that are directly next to your vehicle.
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 a lane marking, can be
corrected at any time if you steer slightly in the
opposite direction.
Distance Pilot DISTRONIC with Steering Pilot
cannot continuously keep your vehicle in lane. In
some cases, the steering intervention is not suf-
ficient to bring the vehicle back to the lane. In
such cases, you must steer the vehicle yourself
to ensure that it does not leave the lane.
The support provided by the system can be
impaired if:
there is poor visibility, e.g. due to insufficient
R
illumination of the road, or due to snow, rain,
fog or heavy spray
there is glare, e.g. from oncoming traffic, the
R
sun or reflections (e.g. when the road surface
is wet)
the windshield is dirty, fogged up, damaged or
R
covered, for instance by a sticker, in the vicin-
ity of the camera
there are no or several unclear lane markings
R
for one lane, e.g. roadworks
the lane markings are worn away, dark or cov-
R
ered up, e.g. by dirt or snow
the distance to the vehicle in front is too short
R
and thus the lane markings cannot be detec-
ted
the lane markings change quickly, e.g. lanes
R
branch off, cross one another or merge
the road is narrow and winding
R
there are strong shadows cast on the road
R
The system is switched to passive and no longer
assists you by performing steering interventions
if:
you actively change lane
R
you switch on the turn signal
R
take your hands off the steering wheel or do
R
not steer for a prolonged period of time
i
After you have finished changing lanes,
Steering Pilot is automatically active once
more.
Driving systems
Steering Pilot cannot provide assistance:
on very sharp corners
R
when towing a trailer
R
when a loss of tire pressure or a defective tire
R
has been detected and displayed
Observe the important safety notes on Distance
Pilot DISTRONIC ( page 176).
Y
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Steering Pilot is
then switched to passive. Distance Pilot
DISTRONIC remains active.
