If driving behaviour becomes seriously erratic, the driver isalerted by means of an acous-tic signal combined with a sym-bol in the driver display and the message
Time for a break
soon?.
The warning is repeated after a time if driving ability does not improve.
NOTE
The function must not be used to extend a period of driving. Always plan breaks at regu-lar intervals, and make sure you are wellrested.
WARNING
An alarm should be taken very seriously, as a sleepy driver is often not aware of his/herown condition. In the event of an alarm or a feeling of tired- ness; stop the car in a safe manner as soonas possible and rest. Studies have shown that it is equally as dan- gerous to drive while tired as it is under theinfluence of alcohol.
WARNING
Driver Alert Control does not work in all situa- tions but is designed merely as a supplemen-tary aid. The driver always bears ultimate responsibility for ensuring that the vehicle is driven safely.

Limitations of Driver Alert Control
The Driver Alert Control (DAC) function may have limitations in certain situations.
In some cases, driving behaviour may not be affected, despite the driver being tired - e.g. whenusing the Pilot Assist function - with the resultthat the driver is then not given a warning fromDAC. For this reason, it is always very importantto stop and take a break in the event of theslightest sign of driver fatigue, regardless ofwhether DAC has given a warning. In some cases the system may issue a warning despite driving ability not deteriorating, for exam-ple:
• in strong side winds
• on rutted road surfaces.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.

Lane Keeping Aid
The function of lane assistance is to help the driver to reduce the risk of the car accidentallyleaving its own lane on motorways and similarmajor routes.
Lane assistance steers the car back into its lane and/or warns the driver with an acoustic signal orsteering wheel vibration. Lane Keeping Aid is active within the speed range 65-200 km/h (40-125 mph) on roads withclearly visible side lines. On narrow roads the function may be unavailable, in which case it goes into standby mode. Thefunction becomes available again when the roadis wide enough.
A camera reads the side lines of the road/lane.

.
Depending on settings, lane assistance acts in accordance with the following:
1. Steering assistance activated: When the car
is approaching a lane line, LKA will actively steer the car back into its lane by applying a slight torque to the steering wheel.
2. Warning activated: If the car is about to cross a lane line, the driver is warned by means ofan acoustic signal or vibration in the steeringwheel.
NOTE
When a direction indicator is switched on, there are no steering corrections or alertsfrom Lane assistance.
WARNING
Lane assistance is merely a driver aid and does not engage in all driving situations ortraffic, weather or road conditions. The driver always bears ultimate responsibility for ensuring that the vehicle is driven safelyand that applicable laws and road traffic regu-lations are followed.

Lane assistance does not intervene
Lane assistance does not engage on sharp inside curves.
In some situations, lane assistance allows lane lines to be crossed without intervening with eithersteering assistance or a warning - e.g. whenusing the direction indicators or cutting bends.
LimitationsIn certain demanding conditions lane assistancemay have difficulty helping the driver correctly. Insuch cases it is recommended to switch off thisfunction. Examples of such conditions are:• road works
• winter road conditions
• poor road surface
• a very “sporty” driving style •
poor weather with reduced visibility
• sharp edges or lines other than the lane lines
• roads with unclear or non-existent line mark- ings.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
