Limitations of Driver Alert Control
The Driver Alert Control (DAC) function may
have limitations in certain situations.
In some cases the system may issue a warn-
ing despite driving ability not deteriorating, for
example:
•
in strong side winds
•
on rutted road surfaces.
WARNING
In some cases, driving behaviour is not
affected despite driver fatigue – e.g. when
using the Pilot Assist* function – resulting
in the driver not getting a warning from
DAC.
It is therefore important to always stop and
take a break at the slightest feeling of fati-
gue, regardless of whether the function has
given a warning.
NOTE
This function uses the car's camera and
radar units, which have certain general lim-
itations.

Cross Traffic Alert*
101
Cross Traffic Alert (CTA) is a driver support
that supplements BLIS
102
and is designed to
help the driver detect traffic crossing behind
the car when it is reversing.
The auto-brake subfunction can help the
driver to stop the car in the event of a risk of
collision with an unobserved vehicle.
Examples of areas where CTA can assist the driver to
detect obstacles during reversing.
CTA is primarily designed to detect vehicles. In
favourable conditions it may also be able to
detect smaller objects, such as cyclists and
pedestrians.
The function is only active if the car rolls back-
wards or if reverse gear has been selected.
If CTA senses that something is approaching
from the side, this is also indicated with:
•
an acoustic signal - the sound is heard in
the left-hand or right-hand speaker
according to the direction from which the
object approaches.
•
an illuminated icon in the
Park Assist
System graphic on the screen.
•
an icon on the Park assist camera top
view.
Illuminated icon for Cross Traffic Alert in the Park
Assist System graphic on the screen.
If the driver does not observe the warning
from CTA and a collision is unavoidable, the
auto-brake function takes effect to stop the
car, after which the driver display shows an
101
Cross traffic alert when the car is reversing.
