Park Assist (PAS1) behaves differently depending on which part of the vehicle is approaching an obstacle.
Front camera
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from the vehicle.
The Park Assist system's front sensors are automatically activated when the engine is started. They are active at speeds below 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 automatic transmission.
CAUTION
When installing auxiliary lights: Make sure these do not obscure the sensors – the auxiliary lights could be perceived as an obstacle.
Back
The warning signal has a continuous tone when the obstacle is less than approx. 30 cm (1 ft) from the vehicle.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear is engaged.
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 is backing up with a trailer connected to the vehicle's electrical system.
NOTE
When reversing with e.g. a trailer or bike carrier on the trailer hitch – without Volvo original trailer cables – the Parking Assist system may have to be turned off manually to prevent the sensors from reacting to these.
Side sensors
The warning signal will begin pulsating rapidly when the obstacle is less than approx. 25 cm (0.8 ft) from the vehicle.
Park Assist's side sensors are automatically activated when the engine is started. They are active 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 increases significantly, however, when the steering angle of the front wheel increases and depending on the position of the steering wheel, obstacles up to approx. 90 cm (3 ft) diagonally behind or in front of the vehicle can be detected.
