CTA is only active during reversing and is
activated automatically when the gearbox's
reverse position is selected.
•
If CTA detects something approaching
from the side, an acoustic warning signal
sounds. The signal comes from either the
left or the right-hand speaker, depending
on the direction from which the object is
approaching.
•
CTA also warns by illuminating the BLIS
lamps.
•
An additional warning is provided in the
form of an illuminated icon in the display
screen's PAS graphics (p. 240).
Limitations
CTA does not perform optimally in all situa-
tions, but has a certain limitation - for exam-
ple, the CTA sensors cannot "see" through
other parked vehicles or obstructing objects.
Here are some examples of when CTA's "field
of vision" may be limited from the beginning
and approaching vehicles cannot therefore be
detected until they are very close:

The car is parked deep inside a parking slot.
Blind CTA sector.
Sector where CTA can detect/"see".
In an angled parking slot CTA can be completely
"blind" on one side.
However, when the driver is slowly reversing
the car, the angle is changed in relation to the
vehicle/object that is blocking, at which the
blind sector rapidly decreases.
Examples of further limitations:
•
Dirt, ice and snow covering sensors can
reduce functionality and make it impossi-
ble to provide warnings. CTA cannot
detect hazards if it is covered.
•
Do not affix any objects, tape or labels in
the area of the sensors.
•
CTA is deactivated when a trailer is con-
nected to the car's electrical system.
IMPORTANT
Repair of the BLIS and CTA functions'
components or repainting the bumpers
must only be performed by a workshop -
an authorised Volvo workshop is recom-
mended.
