Driver support -> Cross Traffic Alert for Your Volvo Xc90 SUV 2020

DRIVER SUPPORT  
Cross Traffic Alert*71  
CTA is only active when the vehicle is moving  
backward or if reverse gear is engaged.  
ble, the auto brake function will intervene to  
stop the vehicle and a text will be shown on  
the instrument panel to explain why the vehi-  
cle was braked.  
Cross Traffic Alert(CTA) is a supplementary  
driver support system to BLIS72 that is  
intended to help the driver detect vehicles  
crossing behind the vehicle while backing up.  
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.  
WARNING  
The auto-brake subfunction can help the  
driver stop the car if there is a risk of collision  
with an unobserved vehicle.  
The function is supplementary driver  
support intended to facilitate driving  
and help make it safer – it cannot han-  
dle all situations in all traffic, weather  
and road conditions.  
an icon will illuminate in the Park Assist  
System graphic on the screen.  
an icon will appear in the Park Assist Cam-  
era's Top view.  
The driver is advised to read all sec-  
tions in the Owner's Manual about this  
function to learn of its limitations,  
which the driver must be aware of  
before using the function.  
Driver support functions are not a sub-  
stitute for the driver's attention and  
judgment. The driver is always respon-  
sible for ensuring the vehicle is driven  
in a safe manner, at the appropriate  
speed, with an appropriate distance to  
other vehicles, and in accordance with  
current traffic rules and regulations.  
Examples of areas in which CTA can help the driver  
detect obstacles while backing up.  
CTA supplements BLIS by detecting traffic  
crossing 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 pedes-  
trians or smaller objects such as bicycles.  
If the driver does not pay attention to the  
warning from CTA and a collision is unavoida-

changes in relation to the obstructing vehicle/  
object and its blind zone is reduced.  
Examples of further limitations  
The auto brake sub-function only detects  
vehicles in motion and may therefore not  
"see" and brake for e.g. stationary obsta-  
cles, a cyclists or a pedestrian.  
Dirt, ice and snow covering the sensors  
may reduce functionality and prevent the  
system from providing warnings.  
CTA is automatically deactivated if a  
trailer, bicycle holder or similar is con-  
nected to the vehicle's electrical system.  
The vehicle is parked very far into a parking space.  
For CTA to function effectively, bicycle  
holders, luggage racks or similar should  
not be mounted on the vehicle's towbar.  
The function uses the vehicle's camera and  
radar sensor, which has certain general  
limitations.

"blind" on one side of your vehicle.
