CTA 82
is a supplementary driver support system
to BLIS 83
that is intended to help the driver
detect vehicles crossing behind the vehicle
while backing up. CTA overview.
CTA supplements BLIS by detecting traffic cross-
ing from the side, e.g. when backing out of a
parking space.
CTA is primarily designed to detect vehicles, but
in certain cases can also detect pedestrians or
smaller objects such as bicycles.
CTA is only active when the vehicle is moving
backward or if reverse gear is engaged. If CTA detects that something is approaching
your vehicle from the side:
an audible signal will sound from either the
left or right speaker, depending on which
side of your vehicle the object is approaching
from.
an icon will illuminate in the PAS 84
graphic
on the screen.
an icon will appear in the Park Assist Cam-
era's Top view. Illuminated CTA icon in the PAS graphic

WARNING
The Cross Traffic Alert function is supple-
mentary driver support intended to facili-
tate driving and make it safer – it cannot
handle all situations in all traffic, weather
and road conditions.
The responsibility for reversing the vehicle
safely and using good judgment always
rests with the driver.
Cross Traffic Alert is not a substitute for
the driver's attention and judgment. The
driver is always responsible for ensuring
the vehicle is driven in a safe manner, at
the appropriate speed, with an appropri-
ate distance to other vehicles, and in
accordance with current traffic rules and
regulations.

CTA 87
functionality may be reduced in certain
situations.
CTA does not function optimally in all situations
and has certain limitations. The CTA sensors, for
example, cannot "see" through other parked
vehicles or objects blocking the vehicle.
Below are a few examples of situations in which
CTA's field of vision may be initially limited and
approaching vehicles may therefore not be
detected until they are very close to your vehicle: 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. 86

Examples of further limitations
Dirt, ice and snow covering the sensors may
reduce functionality and prevent the system
from providing warnings. For additional infor-
mation, see the section "Recommended
maintenance for Cross Traffic Alert".
CTA is automatically deactivated if a trailer,
bicycle holder or similar is connected to the
vehicle's electrical system.
For CTA to function optimally, bicycle hold-
ers, luggage racks or similar should not be
mounted on the vehicle's towbar.

For optimal performance, it is important to
keep the areas in front of the sensors clean.
Do not attach any objects, tape or decals to
the surface of the sensors. Keep the marked area clean (on both the left and right
sides of the vehicle)

The CTA sensors are located on the inside of
each of the rear fenders/bumpers and are also
used by the BLIS 89
and Rear Collision Warning
functions.
CAUTION Repair of BLIS and CTA components or
repainting of the bumper may only be per-
formed by a workshop – an authorized Volvo
workshop is recommended.

Limitations of Run-Off Mitigation
with steering assistance
In certain demanding driving conditions, the
function may not be able to properly assist the
driver. In these situations, it is recommended
that it is turned off.
Examples of such situations include:
road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility
roads with indistinct or no lane markings
sharp edges or lines other than the lane's
side markings
when the power steering works at reduced
power, e.g. during cooling due to overheating
(see section “Speed-dependent steering
force”).
NOTE The function uses the vehicle's combined
camera and radar unit, which has certain gen-
eral limitations; see sections "Camera limita-
tions" and "Radar sensor limitations".

risks from oncoming traffic
This sub-function can help assist a distracted
driver who has not noticed that the vehicle is
veering into oncoming traffic. The function provides assistance by swerving your vehi-
cle back into your own lane.
Oncoming vehicles
Own vehicle
The function is active at speeds between
60-140 km/h (37-87 mph) on roads with clearly
visible traffic lane markings/lines.
If your vehicle is starting to veer from your own
lane and a vehicle is approaching from the oppo-
site direction, this function can help the driver
steer the vehicle back into its own lane.

from oncoming traffic (p. 383) Limitations of steering assistance
during collision risks from

The function may have limited functionality in
certain situations and not intervene, e.g.:

for smaller vehicles such as motorcycles
on roads that do not have clear lane mark-
ings
if more than half of your vehicle has moved
into the adjacent lane
outside the speed range 60-140 km/h
(37-87 mph)
when the power steering works at reduced
power - e.g. during cooling due to overheat-
ing (see section "Speed-dependent steering
force").
Functionality may also be reduced in other situa-
tions, such as:
road work
winter driving conditions
narrow roads
poor road surfaces
a very sporty driving style
bad weather with reduced visibility.
In these demanding driving conditions, the func-
tion may not be able to properly assist the driver. In these situations, it is recommended that it is
