Limitations of Cross Traffic Alert

The Cross Traffic Alert (CTA) function may have
limitations in certain 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 obstructions.
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.
342
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 the driver slowly reverses the car,
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 deactivated when a trailer is con-
nected to the car's electrical system.
Sensors
The sensors for the CTA function are located
inside each corner of the rear wing/bumper. The
sensors are also used by the Blind Spot
Information (BLIS) function.
Keep this surface clean - also on the left-hand side.
To ensure optimal functionality, the surfaces in
front of the sensors must be kept clean.
Do not affix any objects, tape, labels or similar
within 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.
