Lane Keeping Assist
Function of Lane Keeping Assist
Lane Keeping Assist serves to protect you against
unintentionally leaving your lane. You are also
warned by a noticeable vibration in the steering
wheel and by the status symbol flashing in the
instrument cluster. Lane Keeping Assist is only an
aid and is not intended to keep the vehicle in the
lane without the driver's cooperation.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nise dangers ( page 155).
/
The function is available in the speed range
between 60 km/h and 200 km/h.
The warning is issued when the following condi‐
tions are met at the same time:
If Lane Keeping Assist detects lane markings.
R
If a front wheel drives over lane markings.

To ensure that you are warned only when neces‐
sary and in good time if you cross the lane mark‐

warns you accordingly.

R
bend.
the road has very wide lanes, e.g. a motor‐
R

the system detects solid lane markings.

The warning vibration occurs later under the fol‐
lowing conditions:
you are driving on a road with narrow lanes.
R
you cut the corner on a bend.

There is dirt on the windscreen in the vicinity
R
of the multifunction camera or the camera is
misted up, damaged or obscured.
No or several unclear lane markings are pres‐
R
ent for one lane, e.g. in a construction area.
If the lane markings are worn away, dark or
R
covered up.
If the distance to the vehicle in front is too
R
short and thus the lane markings cannot be
