DRIVER SUPPORT
Limitations of Distance Warning
The distance warning function may have limi-
tations in certain situations. The function is
only available in cars that can show informa-
tion on the windscreen with a so-called head-
up display*.
WARNING
A vehicle's size may affect the ability to
•
be detected, e.g. motorcycles, which
could mean that the warning lamp illu-
minates at a shorter time window than
set or that the warning is temporarily
absent.
Extremely high speeds can cause the
•
lamp to illuminate at a shorter time
window than that set due to limitations
in radar unit range.
NOTE
This function uses the car's camera and
radar units, which have certain general lim-
itations.

Cross Traffic Alert*
Cross Traffic Alert (CTA) is a driver support
109
that supplements BLIS 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.
* Option/accessory.
