System limits of the Lane-Keep-
ing S
ystem
Please refer to at the start of the
chapt
er on page 184.
Limits of the sensors
The Lane-Keeping System detects the road
lane markings by means of the camera be-
hind the windscreen.
Pay attention to the limits of the cam-
era → page 166. Always pay due at-
tention and intervene yourself if necessary.
Road lane markings not recognised, or
not recognised correctly
The Lane-Keeping System cannot recog-
nise all lane markings correctly. If road lane
markings are not detected or are incorrectly
detected as such, this can result in no sys-
tem assistance being provided or undesired
interventions by the Lane-Keeping System.
In addition to the situations described in
the section on the camera limits, this can
also happen in the following situations, for
example:
— If there are no road lane markings pres-
ent.
— If your driving style is very dynamic.
— When you are not driving on motorways
or good country roads.
— On poor roads or if there are road struc-
tures or objects.
— In the event of reflections and glare ef-
fects.
Always pay due attention and intervene
yourself if necessary and immediately over-
ride an undesired system intervention.
Switch o the Lane-Keeping System tem-
porarily if necessary.
Lane-Keeping System not ready to per-
form control interventions
The Lane-Keeping System is not ready to
perform control interventions under the fol-
lowing conditions (passive system status):
— The driving speed is less than around
60 km/h (around 35 mph) or more than
around 215 km/h (around 135 mph).
— The Lane-Keeping System has not de-
tec
ted a road lane marking.
— If the lanes are too narrow or in tight
bends.
— Temporarily if the driving style is very dy-
namic.
— If the driver vigorously steers the vehicle
to override a system intervention.
— If the Automatic Emergency Braking sys-
tem performs a control intervention.
The Lane-Keeping System is not ready to
perform control interventions on at least
one side in the following situations:
— If the direction indicator is switched on in
the direction of the planned lane change.
— On the inside of a bend that you are in-
tentionally driving through well to the in-
side.
Interference
WARNING
The eec
tiveness of systems can be ad-
versely aected if components and sys-
tems are retrofitted, e.g. by body builders.
On vehicles with add-ons or modifica-
tions, the correct operation of system can
then be impaired or adjusted. There is
a risk of accidents and serious or even fa-
tal injuries.
·
Have the second stage manufacturer
confirm that the systems are function-
ing properly.
