Rear Collision Warning *63
The Rear Collision Warning 64
(RCW) function
can help the driver avoid rear-end collisions from vehicles approaching from behind.
The function can alert drivers of following vehi- cles of the risk of a collision by rapidly flashingthe turn signals. If, at a speed below 30 km/h (20 mph), the function detects that the vehicle is in dangerof being hit from behind, the seat belt tension-ers may tension the front seat belts. TheWhiplash Protection System will also be acti-vated in a collision. Immediately before a collision from behind, the function may also activate the brakes inorder to reduce the forward acceleration of thevehicle during the collision. However, thebrakes will only be applied if your vehicle isstationary. The brakes will be immediatelyreleased if the accelerator pedal is depressed. The function is automatically activated each time the engine is started.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.

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.
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 sensorsmay reduce functionality and prevent thesystem from providing warnings.
CTA is automatically deactivated if atrailer, bicycle holder or similar is con-nected to the vehicle's electrical system.
For CTA to function effectively, bicycleholders, luggage racks or similar shouldnot be mounted on the vehicle's towbar.

Park Assist front, rear and sides *
Park Assist behaves differently depending on which part of the vehicle is approaching anobstacle.
Front camera
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The Park Assist system's front sensors are automatically activated when the engine isstarted. They are active at speedsbelow 10 km/h (6 mph). The distance monitored extends approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Park Assist system is deactivated when the parking brake is used or when P
is selected on vehicles with automatictransmission.
CAUTION
When installing auxiliary lights: Make sure these do not obscure the sensors – theauxiliary lights could be perceived as anobstacle.
Back
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from thevehicle.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored extends approx. 1.5 meters (5 ft) behind the vehicle. The Park Assist system's rear sensors will be automatically deactivated if the vehicle isbacking up with a trailer connected to thevehicle's electrical system.
NOTE
When reversing with e.g. a trailer or bike carrier on the trailer hitch – without Volvooriginal trailer cables – the Parking Assistsystem may have to be turned off manuallyto prevent the sensors from reacting tothese.

Side sensors
The warning signal will begin pulsating rapidly when the obstacle is less than approx. 25 cm (0.8 ft) fromthe vehicle.
Park Assist's side sensors are automatically activated when the engine is started. They areactive at speeds below 10 km/h (6 mph). The distance monitored is approx. 25 cm (0.8 ft) out from the sides. The detection area of the side sensors increa- ses significantly, however, when the steeringangle of the front wheel increases anddepending on the position of the steeringwheel, obstacles up to approx. 90 cm (3 ft)diagonally behind or in front of the vehicle canbe detected.
