• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is lim-ited in force, which means that it cannotalways help the driver to steer and keepthe vehicle within the lane.
• Pilot Assist is switched off if the powersteering is working with reduced power -e.g. during cooling due to overheating(see section "Speed-dependent steeringforce").
The driver can always correct or adjust steeringassistance provided by Pilot Assist by turning thesteering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be driven onflat roads. The function may not be able to main-tain the correct time interval to the vehicle aheadwhen driving down steep hills. The driver should be extra attentive and prepared to apply thebrakes.

Driver Alert Control
The Driver Alert Control (DAC) function is designed to help capture the driver becomeaware of erratic behavior, e.g. if the driver is dis-tracted or showing signs of fatigue.
The objective of DAC is to detect slowly deterio- rating driving behavior and is primarily intended tobe used on major roads. The function is notintended for use in city traffic. DAC is activated when the vehicle's speed exceeds 65 km/h (40 mph) and remains activeas long as speeds are above 60 km/h (37 mph).
A camera monitors the traffic lane's marker lines and compares the direction of the road with thedriver's movements of the steering wheel.
If the driving behavior becomes noticeably erratic, the driver willbe alerted by this symbol in theinstrument panel and the mes- sage
Time for a break
soon?.
If driving behavior does not improve but instead becomes even more erratic, the driver will bealerted by the same symbol in the instrument panel, an audible signal and the message
Time
for a break.
If the Rest Stop Guidance function is activated
in Sensus Navigation * when the Time for a
break warning is given, suggestions will also be
provided for suitable places to take a break.

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 indriving behavior, e.g.:
• in strong crosswinds
• on grooved road surfaces.
WARNING
In certain cases, driving behavior might not be affected despite the driver's fatigue – whenusing the Pilot Assist function – resulting inthe driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest sign of fati-gue, regardless of whether the DAC functionhas issued a warning or not.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".

) is designed to
actively steer the vehicle on freeways, highways and other major roads to help the driver reducethe risk of the vehicle unintentionally veering outof the lane.

Lane Keeping Aid is active at speeds between 65-200 km/h (40-125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavailable and go into standby mode. The function willbecome available again when the road becomessufficiently wide.
