DRIVER SUPPORT  
Driver Alert Control limitations  
Driver Alert Control (DAC) functionality may  
be reduced in certain situations.  
In certain situations, the system may provide a  
warning even if it has not detected a change in  
driving behavior, e.g.:  
Lane Keeping Aid  
Lane Keeping Aid (LKA89) is designed to  
actively steer the vehicle on freeways, high-  
ways and other major roads to help the driver  
reduce the risk of the vehicle unintentionally  
veering out of the lane.  
Lake Keeping Aid steers the vehicle back into  
the lane and/or alerts the driver using vibra-  
tions in the steering wheel.  
in strong crosswinds  
on grooved road surfaces.  
Lane Keeping Aid is active at speeds between  
65200 km/h (40125 mph) on roads with  
clearly visible traffic lane marker lines.  
WARNING  
In certain cases, driving behavior might not  
be affected despite the driver's fatigue –  
when using the Pilot Assist* function –  
resulting in the driver not getting a warning  
from DAC.  
A camera monitors the road/traffic lane's marker  
lines.  
On narrow roads, the function may be unavail-  
able and go into standby mode. The function  
will become available again when the road  
becomes sufficiently wide.  
It is therefore very important to always  
stop and take a break at the slightest sign  
of fatigue, regardless of whether the func-  
tion has issued a warning or not.  
The function uses the vehicle's camera and  
radar sensor, which has certain general  
limitations.  
Lane Keeping Aid steers the vehicle back into its  
lane.

DRIVER SUPPORT

Lane Keeping Aid does not intervene  
When the direction indicators/turn signals  
are activated, the Lane Keeping Aid does  
not provide any warning or intervene with  
steering.  
WARNING  
The function is supplementary driver  
support intended to facilitate driving  
and help make it safer – it cannot han-  
dle all situations in all traffic, weather  
and road conditions.  
Lane Keeping Aid alerts the driver using vibrations in  
the steering wheel.  
Lane Keeping Aid does not intervene in sharp inside  
curves.  
The driver is advised to read all sec-  
tions in the Owner's Manual about this  
function to learn of its limitations,  
which the driver must be aware of  
before using the function.  
Depending on the settings used, Lane Keep-  
ing Aid functions in different ways:  
In certain cases, such as when a turn signal is  
used or when "straightening out" an inside  
curve, Lane Keeping Aid will not provide steer-  
ing assistance or alerts.  
Assist enabled: When the vehicle  
approaches a lane marker line, the func-  
tion will actively steer the vehicle back into  
the lane using light pressure on the steer-  
ing wheel.  
Driver support functions are not a sub-  
stitute for the driver's attention and  
judgment. The driver is always respon-  
sible for ensuring the vehicle is driven  
in a safe manner, at the appropriate  
speed, with an appropriate distance to  
other vehicles, and in accordance with  
current traffic rules and regulations.  
Hands on the steering wheel  
Steering assistance with Lane Keeping Aid  
only functions if the driver's hands are on the  
steering wheel, which the system continu-  
ously monitors.  
Warning enabled: If the vehicle is about  
to move over a lane marker line, the driver  
will be alerted by vibrations in the steering  
wheel.  
If the driver's hands are not  
on the steering wheel, an  
audible signal will be given  
and a message will instruct  
the driver to actively steer the  
vehicle:  
There is also an option for activating steering  
assistance and alerts at the same time.
