• Driver Alert Control (p. 362) 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".

Driver Alert Control (p. 362) Lane Keeping Aid
Lane Keeping Aid (LKA 107
) 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.

Lane Keeping Aid alerts the driver using vibrations in the
steering wheel
108
. Depending on the settings used, Lane Keeping
Aid functions in different ways:
• With
Assist 109
activated: When the vehicle
approaches a lane marker line, LKA will
actively steer the vehicle back into the lane
using light pressure on the steering wheel.
• With
Warning 109
activated: If the vehicle is
about to move over a lane marker line, the
driver will be alerted by vibrations in the
steering wheel.
NOTE When the direction indicator is activated, the
Lane Keeping Aid does not provide any warn-
ing or intervene with steering.
WARNING •
The Lane Keeping Aid function is supple-
mentary driver support intended to help
improve driving safety – it cannot handle
all situations in all traffic, weather and
road conditions.
• 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. 108
The steering wheel vibrations vary. The more time the vehicle is over th\
e lane marker line, the longer the vibrations.
109 See "LKA assistance options" under "Activating/deactivating Lane Keeping\
Aid".

• a very sporty driving style
• bad weather with reduced visibility
• roads with indistinct or no lane markings

power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").

Park Assist Camera views
PAC can display a 360° panoramic view as well
as separate views for each of the other cameras:
rear, front, left and right.
360° view* The location of the cameras and their approximate fields
of vision.
The 360° view function activates all Park Assist
Cameras and all four sides of the vehicle are
shown in the center display at once to help the
driver see what is around the vehicle while
maneuvering at low speeds.
From the 360° view, each camera view can be
activated separately:
• Tap the screen to select the camera's field of
vision, e.g. in the area in front/above the front
camera. The active cameras will be indi-
cated by a camera symbol on
the vehicle symbol in the center
display.
If the vehicle is equipped with
Park Assist System*, the dis-
tance to detected obstacles will be illustrated by
fields in different colors. The cameras can be activated automatically or
manually. See "Starting the Park Assist Camera"
for more information.
Back
The rear camera
119
is located above the license plate.
The rear camera shows a wide area behind the
vehicle. On certain models, part of the bumper
and the towbar (if installed) may be visible. Objects on the center display may appear to be
leaning slightly. This is normal.
Front camera
The front Park Assist Camera
120
is located in the grille.
The front camera can be useful when pulling out
from areas with limited visibility, such as a drive-
way surrounded by a hedge. The front camera is
active at speeds up to 25 km/h (16 mph) and is
automatically turned off when the vehicle
exceeds this speed.
If the vehicle does not reach a speed of 50 km/h
(30 mph) and speed falls below 22 km/h
(14 mph) within 1 minute after the front camera
turns off, the camera will be reactivated. 119

Blind sectors There are "blind" sectors between the cameras' fields of
vision.
With 360° view selected, objects/obstacles may
not be detected if they are located in the "joints"
where the edges of the individual camera views
meet.
WARNING
Even if it seems as though only a fairly small
section of the screen image is obstructed, this
may mean that a relatively large sector is hid-
den and obstacles there may not be detected
until they are very near the vehicle.
Defective cameraIf a camera sector is dark and
contains this symbol, this indi-
cates that the camera is not
functioning properly.
See the following illustration for
an example. The vehicle's left-side camera is malfunctioning.
Dark camera sector
A dark camera sector may also be displayed in
the following situations, but without the defective
camera symbol:
• a door is open
• the tailgate is open
• a rearview mirror is folded in
Lighting conditionsThe camera image is automatically adjusted
according to the current lighting conditions. This means that the brightness and quality of the
image may vary slightly. Poor lighting conditions
may result in reduced image quality.

Recommended maintenance of the
Park Assist Camera
Each of the Park Assist Cameras, located above
the license plate, the grille and in both door mir-
rors, require a certain degree of maintenance.
Clean the camera lenses regularly using luke-
warm water and car washing detergent. Wash
gently to avoid scratching the lens.
NOTE Keep the camera lens free of dirt, snow and
ice to help ensure the best functionality. This
is particularly important in poor light condi-
tions.
