Lane Keeping Aid - function
Certain settings can be made for the Lane Keep-
ing Aid (Lane Keeping Aid) function.
Lane assistance*
Lane Keeping Aid is one of the functions in the
Driver Alert System - sometimes also referred to
as LKA (Lane Keeping Aid).
WARNING
LKA is merely a driver's aid and does not
engage in all driving situations or traffic,
weather or road conditions.
Off & On
The function is intended for use on motorways
and similar major roads in order to reduce the
risk of the vehicle accidentally leaving its own
lane in certain situations.
The driver always bears ultimate responsibility
for ensuring that the vehicle is driven safely
and that applicable laws and road traffic regu-
lations are followed.
Lane Keeping Aid is active within the speed
range 65-200 km/h (40-125 mph) on roads with
clearly visible side lines. The function is temporar-
ily deactivated on narrow roads with less than 2.6
metres between the lane side lines.

then Lane Keeping Aid will actively steer the car
back into the lane with a slight steering torque in
the steering wheel.

deactivate the function. The button's lamp illumi-
nates when the function is switched on.
Some combinations of the selected equipment
leave no vacant space for an On/Off button in
the centre console - in which case, the function
is instead operated in the car's menu system MY
CAR (p. 113). Here, proceed as follows:
If the car reaches or crosses a side line then
