reversing, such as when reversing out of a park-
ing space.
CTA is primarily designed to detect vehicles. In
favourable conditions, it may also be able to
detect smaller objects, such as cyclists and
pedestrians.
CTA is only active during reversing and is acti-
vated automatically when reverse is selected at
the gearbox.
•If CTA detects something approaching from
the side, an acoustic warning signal sounds.
The signal comes from either the left or the
right speaker depending on which direction
the approaching object is coming from.
•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. 255).
Limitations
CTA does not perform optimally in all situations,
but has a certain limitation - for example, the CTA
sensors cannot "see" through other parked vehi-
cles 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 vehi-
cle/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 impossible
to provide warnings. CTA cannot detect haz-
ards if it is covered.
•CTA is deactivated when a trailer is con-
nected to the car’s electrical system.
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.
Maintenance
The sensors for the BLIS and CTA functions are
located inside the rear wing/bumper on each
corner of the car.
