Important safety notes
If you fail to adapt your driving style, Active

Lane Keeping Assist can neither reduce the

risk of accident nor override the laws of phys-

ics. Active Lane Keeping Assist cannot take

account of road and weather conditions. It

may not recognize traffic situations. Active

Lane Keeping Assist is only an aid. You are

responsible for the distance to the vehicle in

front, for vehicle speed, for braking in good

time and for staying in your lane.
Active Lane Keeping Assist cannot continu-

ously keep your vehicle in its lane.

WARNING

Active Lane Keeping Assist cannot always

clearly detect lane markings.
In such cases, Active Lane Keeping Assist

can:

give an unnecessary warning and then

make a course-correcting brake application

to the vehicle

not give a warning or intervene

There is a risk of an accident.
Always pay particular attention to the traffic

situation and keep within the lane, especially

if Active Lane Keeping Assist alerts you. Ter-

minate the intervention in a non-critical driv-

ing situation.

The system may be impaired or may not func-

tion if:

there is poor visibility, e.g. due to insuffi-

cient illumination of the road, or due to

snow, rain, fog or spray

there is glare, e.g. from oncoming traffic,

the sun or reflections (e.g. when the road

surface is wet)

the windshield is dirty, fogged up, damaged

or covered, for instance by a sticker, in the

vicinity of the camera

the radar sensors in the front or rear bump-

ers or the radiator grill are dirty, e.g.

obscured by snow

there are no, several or unclear lane mark-

ings for a lane, e.g. in areas with road con-

struction work

the lane markings are worn away, dark or

covered up, e.g. by dirt or snow

the distance to the vehicle in front is too

small and the lane markings thus cannot be

detected

the lane markings change quickly, e.g.

lanes branch off, cross one another or

merge

the road is narrow and winding

there are strong shadows cast on the road

If no vehicle is detected in the adjacent lane

and there are broken lane markings detected,

no lane-correcting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel

passes over a lane marking. It will warn you by

means of intermittent vibration in the steer-

ing wheel for up to 1.5 seconds.
Lane-correcting brake application
If you leave your lane, under certain circum-

stances the vehicle will brake briefly on one

side. This is meant to assist you in bringing

the vehicle back to the original lane.

WARNING

A lane-correcting brake application cannot

always bring the vehicle back into the original

lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,

especially if Active Lane Keeping Assist warns

you or makes a lane-correcting brake appli-

cation.
