Cross Traffic Alert*
The Cross Traffic Alert (CTA) function with
auto brake may have limited functionality in
certain situations. Auto-brake is active at
speeds under 15 km/h (9.3 mph).
WARNING
The auto-brake sub-function can only
detect and apply the brakes for other mov-
ing vehicles – not for e.g. stationary obsta-
cles, cyclists or pedestrians.
CTA has certain limitations – The CTA sen-
sors, for example, cannot "see" through other
parked vehicles or objects blocking the vehi-
cle.
Below are a few examples of situations in
which CTA's field of vision may be initially lim-
ited and approaching vehicles may therefore
not be detected until they are very close to
your vehicle:
88 Warning for crossing traffic when the vehicle is backing up.
89 Warning for crossing traffic when the vehicle is backing up.
322
limitations
The vehicle is parked very far into a parking space.
In a diagonal parking space, CTA may be completely
"blind" on one side of your vehicle.
CTA's blind zone.
CTA's field of vision.
However, as you back your vehicle slowly out
of a parking space, CTA's field of vision
changes in relation to the obstructing vehicle/
object and its blind zone is reduced.
Examples of further limitations
The auto brake subfunction only detects
•
vehicles in motion and may therefore not
"see" and brake for e.g. stationary obsta-
cles, a cyclists or a pedestrian.
Dirt, ice and snow covering the sensors
•
may reduce functionality and prevent the
system from providing warnings.
CTA is automatically deactivated if a
•
trailer, bicycle holder or similar is con-
nected to the vehicle's electrical system.
For CTA to function effectively, bicycle
•
holders, luggage racks or similar should
not be mounted on the vehicle's towbar.
NOTE
The function uses the vehicle's radar sen-
sors, which have certain general limita-
tions.
