Volvo XC90: Driver support / Cross Traffic Alert limitations
(* Option/accessory.)
(Warning for crossing traffic when the vehicle is backing up.)
The Cross Traffic Alert (CTA) function with auto brake may have limited
functionality in certain situations. Auto-brake is active at speeds under 15 km/h
(9.3 mph).
WARNING
The auto-brake sub-function can only detect and apply the brakes
for other moving vehicles – not for e.g. stationary obstacles, cyclists or
pedestrians.
The function has certain limitations – the sensors, for example, cannot "see"
through other parked vehicles or objects blocking the vehicle.
Below are a few examples of situations in which the function'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, Cross Traffic Alert may be
completely "blind" on one side of your vehicle.
Blind zone.
The function'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.
Examples of further limitations
- The auto brake subfunction only detects vehicles in motion and may
therefore not "see" and brake for e.g. stationary obstacles, 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 connected to the vehicle's electrical system.
- For CTA to function effectively, bicycle holders, luggage racks or similar
should not be mounted on the vehicle's towbar.
NOTE
The function uses the vehicle's radar sensors, which have certain general
limitations.

Other information:
Park Assist (PAS1) may not be able to detect all conditions in
all situations and functionality may therefore be limited in certain cases.
The driver should be aware of the following limitations for Park Assist:
WARNING
The parking sensors have dead/blind spots where objects cannot be
detected...
The remote key contains a detachable metal key blade that can be used to activate
a number of functions and preform certain actions.
A Volvo workshop can provide you with the key blade's unique code, which is recommended
in case you need to order a new key blade...
