Limitations of Cross Traffic Alert
The CTA
66
function may have limitations in cer-
tain situations.
CTA does not perform optimally in all situations
but has some limitations. For example, the CTA
sensors cannot "see" through other parked vehi-
cles or obstructing obstacles.
Here are some examples of situations where
CTA’s "field of vision" may be already limited and
approaching vehicles cannot therefore be
detected until they are very close:
The car is parked deep inside a parking slot.
In an angled parking slot CTA may be completely “blind”
on one side.
Blind CTA sector.
Sector in which CTA can detect/“see”.
However, as your car slowly reverses, the angle it
makes with the obstructing vehicle/object
changes and the blind sector rapidly decreases.
Examples of further limitations:
Dirt, ice and snow covering the sensors may
reduce the functions and deactivate alerts.
CTA is automatically deactivated if a trailer,
bicycle rack or similar is connected to the
car's electrical system.
For optimal performance of CTA, no bicycle
rack, luggage carrier or similar should be
mounted on the car's towbar.
Sensors
The sensors for CTA are located inside each cor-
ner of the rear wing/bumper. The sensors are
also used by the BLIS
67
function.
Keep the surface clean - on both the left and right-hand
sides of the car.
To ensure optimal functionality, the surfaces
in front of the sensors must be kept clean.
Do not affix any objects, tape or labels in the
area of the sensors.
IMPORTANT
Repair of the BLIS and CTA functions' com-
ponents or repainting the bumpers must only
be performed by a workshop - an authorised
Volvo workshop is recommended.
