WARNING
The Driver Alert Control function is sup-
plementary driver support intended to
facilitate driving and help make it safer –
it cannot handle all situations in all traffic,
weather and road conditions.
Driver Alert Control must not be used to
extend a period of driving. The driver
should plan in breaks at regular intervals
and make sure they are well rested.
Driver Alert Control is not a substitute for
the driver's attention and judgment. The
driver is always responsible for ensuring
the vehicle is driven in a safe manner, at
the appropriate speed, with an appropri-
ate distance to other vehicles, and in
accordance with current traffic rules and
regulations.
WARNING An alarm from Driver Alert Control should be
taken very seriously since a sleepy driver is
often not aware of their own condition.
If the alarm sounds or you feel fatigued:
Stop the vehicle safely as soon as possi-
ble and rest.
Studies have shown that it is just as danger-
ous to drive while tired as it is to drive under
the influence of alcohol or other stimulants.

Driver Alert Control (p. 370) 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.:
in strong crosswinds
on grooved road surfaces.
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.
It is therefore very important to always stop
and take a break at the slightest sign of fati-
gue, regardless of whether the DAC function
has issued a warning or not.
NOTE
The function uses the vehicle's camera unit,
which has some general limitations – see the
section "Camera unit limitations".

Camera limitations (p. 338) Lane Keeping Aid
Lane Keeping Aid (LKA 104
) is designed to
actively steer the vehicle on freeways, highways
and other major roads to help the driver reduce
the risk of the vehicle unintentionally veering out
of the lane.
Lake Keeping Assistance steers the vehicle back
into the lane and/or alerts the driver using vibra-
tions in the steering wheel.
Lane Keeping Aid is active at speeds between
65-200 km/h (40-125 mph) on roads with
clearly visible traffic lane marker lines.
On narrow roads, the function may be unavailable
and go into standby mode. The function will
become available again when the road becomes
sufficiently wide. A camera monitors the road/traffic lane's marker lines.

380 Steering assistance at risk of
collision
The Collision avoidance assistance function
is intended to help the driver reduce the risk of
the vehicle inadvertently veering from the traffic
lane and/or colliding with another vehicle or
obstacle by actively steering the vehicle back
into the lane and/or swerving out of the way.
Collision avoidance assistance consists of
three sub-functions:
Run-Off Mitigation with steering assistance
Steering assistance during collision risks
from oncoming traffic
Steering assistance during collision risks
from behind*
After the system has automatically intervened,
this text message will appear in the instrument
panel:
Collision avoidance assistance –
Automatic intervention
NOTE It is always the driver who must decide how
much the vehicle should be in control – the
vehicle can never take command.

WARNING
The "Steering assistance at risk of head-
on collision" subfunction is supplemen-
tary driver support intended to improve
driving safety – it cannot handle all situa-
tions in all traffic, weather and road condi-
tions.
Pilot Assist is only activated if there is a
high risk of collision – you must therefore
never wait for the function to intervene.
The function is not a substitute for the
driver's attention and judgment. The driver
is always responsible for ensuring the
vehicle is driven in a safe manner, at the
appropriate speed, with an appropriate
distance to other vehicles, and in accord-
ance with current traffic rules and regula-
tions.

The function may have limited functionality in
certain situations and not intervene, e.g.:

for smaller vehicles such as motorcycles
if more than half of your vehicle has moved
into the adjacent lane
on roads/lanes with indistinct or no side lane
markings
outside the speed range 60-140 km/h
(37-87 mph)
when the power steering works at reduced
power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").
Functionality may also be reduced in other situa-
tions, such as:
road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.
In these demanding driving conditions, the func-
tion may not be able to properly assist the driver.
In these situations, it is recommended that it is
turned off.
